Post-Deactivation Surveillance and Maintenance Planning
Post-Deactivation Surveillance and Maintenance
Planning
Dependence of
End-Points Planning on S&M Planning
One of the key elements of end-point planning is knowing what the
post-deactivation S&M activities will be so that conditions can be
established to support them. The post-deactivation S&M plan specifies the
surveillance, inspection, and maintenance of the facility in the deactivated
state. It should address the activities, the locations in which they will be
conducted, and their frequency. Part of the S&M planning is deciding which
spaces must be accessed and which equipment must be operated. This should be
agreed upon with the organization that will receive the facility for subsequent
S&M and, where needed to meet a stakeholder, regulatory, and tribal nations
commitment.
DOE
G 430.1-2, IMPLEMENTATION GUIDE FOR SURVEILLANCE AND MAINTENANCE DURING FACILITY
TRANSITION AND DISPOSITION
addresses excess facility S&M.
A preliminary Post-Deactivation S&M Plan should be developed to support the
End-Points Description and Criteria. Conditions will determine the S&M
requirements, but the cost of meeting certain end-point criteria must be
balanced against the cost of the S&M. In some cases, it may be necessary to
perform life-cycle-cost analysis to determine the final end-point.
It would be imprudent to await a complete, final, detailed S&M plan before
end-point planning. Indeed, in some cases, S&M plans may be constrained by
what can be accomplished during deactivation. Thus, developing an S&M plan
can become an iterative effort with deactivation end-point planning. However,
it is important for purposes of end-point planning that a preliminary S&M
plan be written as soon as possible during deactivation, even if the full
details cannot be specified.
Another important reason for early preparation of the S&M plan is that
people who have operated and maintained the facility have considerable
knowledge and are in good position to recommend what the activities should be.
Thus, developing the plan in the early stages should be a cooperative effort
between the deactivation organization and the receiving organization.
Primary Surveillance
Concerns
Under the presumption that many facilities will be deactivated to a passive
state, the primary concerns for surveillance are related to:
-
| 1) |
animal intrusion |
| 2) |
structural integrity degradation |
| 3) |
water in-leakage |
| 4) |
contamination migration |
| 5) |
unauthorized personnel entry |
In addition, for facilities where there is intrinsic economic value and for
which the ultimate disposition is likely to be to commercial or private
entities, theft protection becomes important. This is not likely to be the case
for old, radioactively contaminated facilities.
Typical Post-Deactivation
S&M Plan Contents
The contents of a Post-Deactivation S&M plan will vary in scope and content
from project to project. In general, the plan should address:
-
Routine S&M activities.
-
Deviations from the S&M routine, special inspections, and activities
conducted infrequently.
-
Unusual situations or unsatisfactory conditions.
Typical contents of the post-deactivation S&M plan are:
-
Introduction - Define the envelope and buildings in the facility that is
subject of the S&M plan. Provide a plot plan type sketch or drawing to
indicate the scope. Describe any unusual situations such as portions of a
building that may remain operational and managed by a different organization.
-
Purpose - Briefly outline the specific objectives of the post-deactivation
S&M phase. Objectives can relate to contamination control, physical
security, hazard isolation, preservation of economic assets, and others. The
specific types of activities are addressed later. The planned level of effort
to conduct S&M should be stated - for example, effort minimized to the
degree feasible.
-
Background (optional) - Appropriate if there are special circumstances that
might affect the S&M plan. For example, modifications to the authorization
basis and safety category of the facility. If a reference to the operating
background of the facility is to be included, it would be better to rely on
other documents for this purpose and to refer to them, rather than write new
documents solely for purposes here.
-
Description of Surveillance and Maintenance Activities - This section
should address the areas of surveillance and maintenance listed in DOE G
430.1-2, Section 5.3. This is the key part of the S&M plan and is likely to
be the most extensive. Example sections are:
| 1) |
Facility Operations |
| 2) |
Facility Maintenance |
| 3) |
Quality Assurance |
| 4) |
Radiological Controls |
| 5) |
Hazardous Material Protection |
| 6) |
Health and Safety/Emergency Preparedness |
| 7) |
Safeguards and Security |
| 8) |
Cost and Schedule |
-
Regulatory Compliance - Describe how regulations applicable to the specific
facility configuration and conditions, as well as any special agreements with
the State and/or Tribal Nations, are to be addressed during post-deactivation
S&M mode.
-
References - List references that have specifically been used for the
post-deactivation S&M planning. Do not refer to general documents, such as
regulations or DOE orders, unless there is some unique aspect of the
post-deactivation S&M Program that is a direct implementation requirement.
Example of a
Post-Deactivation S&M Plan
The post-deactivation S&M plan for the UO3
facility at Hanford is provided as an example. The reader is advised to
judiciously review the contents and ensure appropriate application prior to
use. (For example, much of this may not be needed for a relatively simple
facility. A checklist might suffice.) Also not that this example is
several years old and some of the organization and document references may no
longer exist.
UO3 FACILITY SURVEILLANCE AND MAINTENANCE PLAN
I. Introduction
This document describes the surveillance and maintenance (S&M) plan for the
UO3 Plant after deactivation is complete, up to the initiation of
decommissioning. The S&M activities will be integrated into the
decommissioning work and phase out as decommissioning is completed.
A tailored approach was used to determine which elements of the various DOE
orders apply to the UO3 Plant during the S&M period. Since the UO3 Plant
has been reclassified from a nuclear facility to an industrial facility and
will be unoccupied, many of the elements do not apply.
The S&M plan includes the following sections:
-
Introduction
-
Background
-
Purpose
-
Transition Activities

Progress Reports
The UO3 Facility is shown in Figure 1 (in original, not included in this
handbook) and for the purpose of this S&M plan is defined as follows:
-
The 224-U building, 224-UA building, 272-U building, 2715-U, 2715-UA, 2716-U,
203-U, 203-UX, UNH truck pad, the waste shed, six 100,000 gallon tanks in the
211-U tank farm, 211-U 307 Pump Pit, 211-U Acid Loading Station, the 207-U
Retention Basin, and 207-U Sample Shack.
The 2714-U building and T-hopper storage pad which were part of the UO3
Facility when it operated will not be transferred to the EM-40 program until
later since the UO3 powder from previous campaigns is still stored in T-hoppers
on the pad and depleted UO3 from previous campaigns is stored in drums inside
the 2714-U building. This area will be deactivated and transferred to EM-40
later along with the PUREX Plant.

II. Purpose
The purpose of this S&M plan is to describe the S&M program for the UO3
Facility from the time that deactivation is complete up to initiation of
decommissioning. The S&M program will be phased into operational activities
when decommissioning begins. The S&M plan may need to be upgraded as
preparations are made for decommissioning.
The number of people that have access to the facility will be kept to a minimum
during S&M. This minimizes the safety requirements that must be met for the
facility that in turn minimizes the cost of the S&M program.
Specific objectives of the S&M program for the UO3 facility are as follows:
| 1) |
Ensure adequate containment of contamination. |
| 2) |
Provide physical safety and security control. |
| 3) |
Maintain the facility in a manner that will minimize
potential hazards to the public. |
| 4) |
Provide a mechanism for the identification and
compliance with applicable environmental, safety, and health requirements. |
III. Background
The UO3 Plant was used to convert uranyl nitrate hexahydrate solution from the
PUREX Plant into a solid UO3 powder. The UO3 Plant processing schedule was
determined by the PUREX uranium product inventory buildup. The last operating
campaign was completed in June 1993. Deactivation of the facility began as soon
as the campaign was finished in preparation for transfer from the DOE EM-60
program to the EM-40 program. At that time, surveillance and maintenance
responsibilities for the UO3 Plant will be transferred from Westinghouse
Hanford Corporation (WHC) to Bechtel Hanford Incorporated (BHI).
The purpose of the deactivation project was to establish a passively safe and
environmentally secure configuration for the UO3 Facility and preserve that
configuration for a ten year horizon. When deactivation is completed, the plant
will be unoccupied, empty of portable equipment and furniture, and locked.
A hazards classification evaluation was done for the UO3 Facility in a
deactivated state. The evaluation determined that the facility could be
reclassified from a nuclear facility to an "other industrial facility" with no
hazardous waste activities when deactivation is completed. The determination
was based on the fact that nearly all radioactive material and hazardous
materials have been removed. The hazards classification evaluation was done per
DOE-EM-STD-5502-94, Hazard Baseline Documentation, and reported in
WHC-SD-CP-HC-004, UO3 Building Hazards Classification - Deactivated State.
The UO3 Plant Final Safety Analysis Report
, SD-CP-SAR-002, will be archived when deactivation is completed since an FSAR
is not needed for industrial facilities.
During deactivation, the UO3 Facility was stabilized so that when it is
transferred to the EM-40 program, only a minimal effort would be required for
S&M activities. All process equipment, instrumentation, and HVAC systems in
the UO3 Facility were shut down. During S&M, the buildings will be
unoccupied and there will be only quarterly monitoring of the facility
condition. The building doors and the gates in the perimeter fence will be
locked to limit access. The facility will be entered only for quarterly
surveillance or to correct deficiencies identified during the surveillance
entries.
The following activities have been completed to isolate source material and
mitigate contamination migration:
-
Process ventilation stacks were isolated (capped or blanked).
-
All water sources have been isolated to the individual buildings. The main
underground headers will be blanked after facility transfer to ensure no
in-leakage occurs.
-
Heating, Ventilation and Air Conditioning (HVAC) have been sealed to reduce the
potential migration of contamination and to keep water and small animals out.
-
Miscellaneous wall penetrations were sealed.
-
Electrical power was disconnected and in the case of 224-U and 224-UA, lighting
was installed or modified to allow safe performance of the surveillance.
-
All drains to the sanitary sewer were sealed thus isolating the buildings from
the sanitary sewer.
-
The main incoming steam to the UO3 facility has been shut off and the main
isolation valve lock/tagged closed. KEH Utilities will remove the valve during
the scheduled spring outage. This valve removal has been added to the
Post-Transition Punchlist.
-
All sumps and floor drains were sealed and either plugged or grouted.
-
The trench that runs from 224-UA to 224-U (C-cell) was tied into the 207-U
retention basin pipe for routing of storm water buildup from the backside
contamination zone areas to the 207-U basins for solar evaporation.
-
All sinks and toilets were removed and sealed.
-
Blind flanges and blanks were used to isolate pipes containing UO3 powder from
the process system.
-
The cover plates on the 203-U enclosure trench were replaced with grating to
assist in evaporation of storm water.
-
All "no access" doors and large roll up type doors were sealed using an
expansion foam.
-
Door sweeps were repaired and/or verified to be in good condition to minimize
potential vermin infestation.
IV. Transition Activities
The UO3 Facility will be officially transferred from the DOE EM-60 program to
the EM-40 program by a Memorandum of Agreement. The UO3 facility will be
accepted "as is" by EM-40 except for a few elements of the deactivation
endpoint criteria that have not been met at the time of transfer. These items
have been placed on a punchlist and will be finished after deactivation is
complete using EM-60 funding. The details of how the work will be completed
will be addressed in the Memorandum of Agreement.
Endpoint criteria for deactivation activities have been defined in
WHC-SD-WM-TPP-052, UO3 Deactivation End-Point Criteria
. Documentation that the endpoint criteria have been met is provided by the
signatures on endpoint criteria tracking sheets. The tracking sheets have been
signed by both the UO3 Plant Deactivation Management (WHC) and Decommissioning
Projects, Inactive Facilities Surveillance and Maintenance (BHI).
Post-Transition Punchlist items from the endpoint criteria will be completed
after facility transfer using EM-60 funding. The items are listed below and
described briefly in the paragraphs that follow.
| 1) |
Closure of QUEST item TTA-90-0000-A/BMPF-8. |
| 2) |
Application of a sealant to the 224-UA building roof to
verify the building structural integrity for a minimum of five years. |
| 3) |
Removal of dangerous and mixed waste drums from the
90-day waste storage pad. |
| 4) |
Isolation of the main raw and sanitary water headers to
the UO3 Plant at the most consolidated point upstream from the facilities and
drain lines. |
| 5) |
Isolation of steam at the most consolidated point
upstream from the facilities and drain lines. |
| 6) |
Supply lighting electrical supply drawings as part of
the turnover package. |
| 7) |
Complete TPA milestone M-80-00-T02. This milestone
requires the facility to be deactivated and transferred to EM-40. |
All QUEST items have been closed except item TTA-90-0000-A/BMPF-8. The DOE is
required to verify closure of this item.
The roofs of buildings 224-U, 224-UA, and 272-U were inspected during 1994 and
the 272-U roof was coated with weather tight sealant as recommended after the
inspection. Application of sealant to the 224-UA roof was also recommended, but
it was not finished before deactivation was completed since the sealant cannot
be applied in cold weather. Roof repairs will be completed in the spring of
1995 (funded by EM-60).
Radioactive mixed waste was generated at the UO3 Plant from decontamination
work on the loadout pads right up to completion of deactivation. The waste
drums containing paint residues from the loadout pads and some containing oil
must be sampled and the waste characterized before the drums can be shipped
from UO3 Plant. A few drums of radioactive mixed waste may still be on the
90-day storage pad when deactivation is complete. WHC personnel will retain
responsibility for inspection, characterization, and shipment of the waste
drums using EM-60 funding.
The raw water and sanitary water supplies to the 224-U, 224-UA and 272-U
buildings were isolated outside the buildings as deactivation proceeded.
However, blanking of the main supply header to the UO3 facility will not be
completed until later since water is needed until deactivation activities are
nearly completed. Permanent isolation of the raw water headers to the UO3
Facility requires excavation down to the buried headers and installation of
blanks at a number of locations. This work will not be finished until after
deactivation is completed due to the magnitude of the effort involved and the
possibility that the work will be slowed by inclement weather. This work will
be completed in the first half of CY-95 using EM-60 funding.
The main incoming steam isolation valve to the UO3 facility has been locked
closed (with vent/drain lines open downstream). Kaiser Engineers Hanford (KEH)
Utilities will remove the valve and install blind flanges during the 200 West
area steam outage scheduled for the spring of 1995.
Electrical lighting field work is complete, however the applicable drawings
have not been updated to reflect current configuration. This will be done after
deactivation is completed.
Historical records for the UO3 Facility will be turned over to BHI at the time
of facility transfer. These records will be stored by BHI for reference during
both the S&M period and when decommissioning activities begin. These
records will include the following as a minimum:
-
Endpoint criteria tracking sheets
-
Deactivation work plans
-
Deactivation log books
-
Final radiation surveys
-
Unusual Occurrence Reports
-
Essential and general drawings of the facility
-
Correspondence and backup information to support the endpoint criteria
completion
-
S&M procedure
-
Safety analysis documentation
-
Facility emergency plan information
-
Chemical/hazardous substance inventory
-
Fire hazards analysis
-
Final inventory of special nuclear material
V. Description of Surveillance and Maintenance Activities
This section describes the surveillance and maintenance activities for the UO3
Facility. It is divided into the eight areas of surveillance and maintenance
that are outlined in the DOE EM-40 Decommissioning Resource Manual
(circa 1993.)
A. Facility Operations
During the S&M period, the UO3 plant will comply with the applicable
sections of the DOE order for S&M of inactive DOE Facilities. Surveillance
activities at the UO3 Plant will be conducted in accordance with WHC-CM-6-8, Hanford
Restoration Operations Administration
, Section 1.1, "Surveillance and Maintenance" (or equivalent BHI procedure).
All operating equipment inside the UO3 plant perimeter fence will be shut down
by the time deactivation is completed. Facility operations will be limited to
the following activities:
-
Environmental monitoring of the 207-U Basin area
-
Quarterly entries into the yard areas and the 224-U and 224-UA buildings for
surveillance
-
General housekeeping activities
The 207-U basins collect runoff from the roofs of the 224-U and 224-UA
buildings and adjacent concrete pads. The outlets from the basins have been
isolated and the accumulated water will be allowed to evaporate. The
Operational Environmental Monitoring Program (OEMP) will continue to monitor
the air and soil in the vicinity of the basins. This is done to show compliance
with the National Emission Standards for Hazardous Air Pollutants (NESHAP)
requirements for monitoring and estimation of emissions from diffuse and
fugitive sources. The monitoring will be done using the existing equipment and
is funded by the current environmental monitoring program.
The quarterly surveillance entries of the UO3 Facility will consist of a
walk-through of the yard areas, building 224-U, and building 224-UA to check
for any indication of structural defects, roof deterioration, posting
deficiencies, water intrusion, animal or insect intrusion, hazardous conditions
or unlabeled containers. Entries into the process cells will require a minimum
of three people including one health physics technician. The S&M procedure
will provide direction for the surveillance entries and include data sheets to
document observations.
General housekeeping activities including tumbleweed removal and sand cleanup
from outdoor contamination areas will be required during the S&M period.
B. Facility Maintenance
Since the deactivated UO3 Facility has been reclassified from a nuclear
facility to an industrial facility, a Maintenance Implementation Plan was not
required by the DOE Order 4330.4B. Maintenance activities will be covered by
the maintenance program described in WHC-CM-6-8, Section 1.1, "Surveillance and
Maintenance," or the BHI equivalent.
Since there will be no operating process equipment or HVAC system at the UO3
Facility, very little routine maintenance will be required. The only electrical
equipment that will be maintained is the lighting circuits in the 224-U and
224-UA buildings. The power to the lighting circuits will only be switched on
for surveillance entries. Defective light bulbs will be replaced during
surveillance entries. Repairs to the lighting circuitry will be made when
necessary.
Periodic inspections for roof and structural integrity will be the most
frequent maintenance activity.
The roofs of buildings 224-U, 224-UA, and 272-U were inspected by a structural
assessments senior engineer on September 9, 1994. The following actions were
recommended:
| 1) |
Re-inspect the 224-U roof at an interval of four years. |
| 2) |
Re-inspect the 224-UA roof at an interval of one year. |
| 3) |
Re-inspect the 272-U roof at an interval of two years. |
| 4) |
Seal the roofs of the 224-UA and 272-U buildings with
an elastomer protective barrier to prevent in-leakage. |
| 5) |
Perform an annual membrane inspection on the 224-U
building. |
| 6) |
Provide additional sealing material to all the pitch
pans on the 224-U building roof to prevent in-leakage. |
Items 1, 2, 3, and 5 are included in the surveillance and maintenance (S&M)
procedure. The roofs of the 272-U and 224-UA buildings have been (or will be)
sealed with an elastomer protective barrier as recommended in Item 4. If
application of the protective barrier is not completed at the time of facility
transfer, it will be completed in the spring of 1995 using EM-60 funding. Item
6 was completed as part of deactivation.
In addition to the roof inspections, structural assessments will be performed
on the 224-U, 224-UA, and 272-U buildings every five years as recommended by
the structural assessments senior engineer.
Roof repairs or replacement approximately every 20 years is the largest
maintenance activity anticipated. Building demolition will be evaluated as an
alternative to roof repairs.
C. Quality Assurance
The UO3 Plant will be included in the quality assurance program described in
WHC-CM-6-8, Section 2.0 "Hanford Restoration Quality Assurance Program Plan,"
or the BHI equivalent.
D. Radiological Controls
During the S&M period, the UO3 plant will comply with the applicable
sections of DOE Order 5480.11, Radiation Protection for Occupational Workers.
Radiological control activities will be conducted as described in HSRCM-1 Hanford
Site Radiological Control Program, WHC-CM-1-6 Radiological Control
Program, WHC-CM-4-11, ALARA Program
, or the BHI equivalent to these documents.
The following paragraphs describe how specific elements of radiological control
will be implemented at the UO3 Facility during the S&M period.
D.1 External and Internal Radiation Exposure Control and Dosimetry
Radiological conditions at the UO3 Plant will be assessed and Radiation Work
Permits prepared prior to each quarterly surveillance entry. The radiation work
permit will specify protective clothing, respiratory protection requirements,
and the activities that are permitted during the surveillance entry.
D.2 Air Monitoring
A program has been established to monitor radon levels inside the 224-U and
224-UA buildings. For each quarterly surveillance entry, Radiological
Protection personnel will enter the area to collect the radon monitors. The
information from the monitors along with contamination smears will be used to
determine the respiratory protection and clothing requirements.
D.3 Radiological Monitoring and Contamination Control
Health Physics Technicians will assess the radiological conditions in the UO3
Facility for each quarterly entry as described earlier. They will also
accompany surveillance personnel on the quarterly surveillance walk-through of
radiation zones to monitor radiological conditions and to check for the spread
of contamination. During these surveillance entries, personnel will check for
evidence of animal or insect intrusion that may result in contamination spread.
D.4 Radiological Protection Record Keeping
Historical radiation survey data and other radiological records will be turned
over to BHI at the time of facility transfer. These records will be stored by
BHI for reference during both the S&M period and when decommissioning
activities begin.
D.5 Radiological Area Boundaries, Postings, and Controls
Radiological area boundaries are posted and controlled at the UO3 Facility as
required by the above listed documents. The postings will be checked during the
quarterly surveillance entries. There are no fissile materials present in the
UO3 Facility, nor any high or very high radiation areas.
E. Hazardous Material Protection
All hazardous waste was removed from the UO3 Facility during deactivation or
will be removed within 90 days following generation and staging on the 90-day
pad. The following hazardous materials will remain at the UO3 Facility during
the S&M period:
-
Mercury switches and lead/silver solder that are part of instrumentation in the
control room, switchgear room and other locations. All visible mercury switches
have been removed, but others remain inside equipment.
-
Solidified uranyl nitrate hexahydrate in the drain lines from the ED-6
concentrator and TK-X-19 (no more than 15 gallons).
-
Dioctyl phthalate (DOP) contamination in the HEPA filters left in the 224-UA
loadout room and on the 224-UA roof.
-
Approximately 2 liters of solidified UNH in the concrete-lined 203-U riser pit
(30 feet below grade).
-
Potential PCB or DOP bearing ballasts in the remaining light fixtures.
-
Asbestos insulation on piping and vessels.
The abandoned 270-W tank located under the 2715-UA building will remain as is.
The tank contents, if any, are unknown at this time. The WHC Tank Waste
Remediation organization has taken responsibility for this tank and will
perform a safety investigation and assessment in the future. Tank Waste
Remediation Support (WHC) and EM-40 will need a separate agreement for access
and work control associated with investigation of the 270-W tank contents.
The hazardous wastes described above will remain in the UO3 Facility through
the S&M period. The wastes will be identified in WHC-SD-DD-HIE-002, Hanford
Surplus Facilities Hazards Identification Document
, or the BHI equivalent. During the quarterly surveillance entry, personnel
will check for friable asbestos, unidentified/unlabeled containers, and suspect
hazardous materials.
F. Health and Safety/Emergency Preparedness
A hazards assessment was conducted to determine the need for emergency planning
at the UO3 Facility per DOE Order 5500.3A. The hazards assessment was reported
in WHC-SD-PRP-HA-001, Rev. 2, UO3 Plant Hazard Assessment
. The assessment concluded that there is negligible risk to people outside the
facility from the residual material at the UO3 Facility. Nearly all radioactive
materials and hazardous materials have been removed. However, the T-hopper
powder storage (which will not be transferred to the EM-40 program until later)
can threaten the safety of personnel at the deactivated UO3 Plant and at U
Plant.
Since the UO3 Facility will not be occupied and the residual material in the
facility presents negligible risk to people outside, an emergency plan is not
required.
A fire hazard analysis (FHA) was completed for the UO3 Facility per DOE Order
5480.7A, Fire Protection. The FHA, WHC-SD-WM-FHA-003, Fire Hazards
Analysis for the Uranium Oxide (UO3) Facility
, concluded that all fire suppression and alarm systems could be deactivated.
All known fire hazards and substantial amounts of combustible materials have
been removed from the facility. Two fire hydrants located on opposite sides of
the building complex provide adequate fire protection water supply to the
facility.
During the quarterly surveillance entry, personnel will check for excess
combustible materials, electrical hazards, occupational hazards, and
housekeeping deficiencies.
G. Safeguards and Security
Since the deactivated UO3 Facility no longer has accountable quantities of SNM,
vital equipment, or classified information, DOE Order 5632.2A, Physical
Protection of Special Nuclear Material and Vital Equipment and DOE
Order 5480.5 Safety of Nuclear Facilities
do not apply to the UO3 facility during S&M. It has been reclassified from
a Nuclear Facility to the "Other Industrial Facilities" category. However,
access to the facility will be controlled to prevent radiation exposure or
injury to personnel.
Access to the fenced areas and buildings of the UO3 facility will be controlled
by BHI Decommissioning Projects, Inactive Facilities, which will have
possession of the security keys to unlock gates and doors. Access will be
limited to personnel who have current training or are escorted by trained
personnel. Access Control for the UO3 Plant and other excess facilities is
described in WHC-CM-6-8, Hanford Restoration Operations Administration
, Section 1.3, "Surplus Facilities Access Control" or BHI equivalent.
Physical access control to buildings 224-U, 224-UA, 272-U, nearby smaller
buildings and the adjacent yard area at the UO3 Plant is provided by a 8' high
chain link fence topped by 3 strands of barbed wire. Vehicle access gates are
located in the SW and NE sides of the perimeter fence. A pedestrian gate is
located near the west corner. All of the gates in the perimeter fence will be
locked when the UO3 Facility deactivation is completed. The doors to all the
buildings inside the fence will also be locked or sealed to provide additional
access control.
The 211-U tank farm is cordoned off with magenta and yellow chain with
applicable radiological status postings, but is not fenced. There are no
intrusion alarms at any of the UO3 Facilities.
There will not be any routine security patrols within the perimeter fences of
the UO3 facility. Hanford Patrol will continue to provide routine security
patrols in the vicinity as part of their patrols throughout the 200 West area.
H. Cost and Schedule
A brief description and work breakdown structure for the UO3 Facility
surveillance and maintenance activities are given below. The air and soil
monitoring around the 207-U basins is not included in the cost breakdown
because it is not funded out of the Surplus Facilities budget. The
Post-Transition Punchlist activities that will be finished after facility
deactivation is completed also are not included since those activities are part
of the PUREX/UO3 Deactivation Project. That work will be funded by the
deactivation project except for the steam valve removal that is part of a
planned steam valve replacement.
The EM-60 program through FY-95 will fund the UO3 Facility surveillance and
maintenance work. Starting in FY-96, it will become part of the EM-40 program.
Four surveillance entries will be made each year on a quarterly basis beginning
in February 1995.
