v REVISION 0

GENERAL INFORMATION SECTION 1 GENERAL INFORMATION The Westinghouse Electric Corporation (Westinghouse) Test Reactor (WTR) is located on the Waltz Mill Site near Madison, Pennsylvania. The retired WTR is currently licensed under Nuclear Regulatory Commission (NRC) License TR-2. The balance of the Waltz Mill Site is licensed and operated under NRC License SNM-770.

Westinghouse is developing a detailed Decommissioning Plan (" Plan") to address the activities required to terminate the TR-2 License. It is considered reasonable and prudent that the activities i required for license termination are: removal of the remaining reactor vessel internal contents, the reactor vessel, and the biological shield. Following these decommissioning activities, l Westinghouse will be requesting transfer of the remaining residual radioactivity to the SNM-770 License. The Plan will describe these decommissioning activities and the required interfaces with the SNM-770 licensed site. ,

1 Prior to or during TR-2 license termination, the SNM-770 License will be amended to include the plans and costs for remediation of the structures, materials, and equipment transferred from the TR-2 License. Future use of these structures, materials, and equipment shall be in accordance with the SNM-770 license conditions and site procedures controlling occupational exposure and exposure to the public.

This document outlines the Plan being developed for the WTR, identifies the basic format /information to be provided and assumptions that will form the Plan. The Plan is being prepared using Draft Regulatory Guide DG-1005, " Standard Format and Content for Decommissioning Plans for Nuclear Reactors" (Ref.1) and the applicable regulatory requirements associated with 10 CFR 50.82(b). Although DG-1005 is still in draft form, it is considered appropriate for the development and general format of the Plan. The standard format of DG-1005 has been slightly altered for consistency with the Waltz Mill Facility SNM-770 Remediation Plan, previously submitted to the NRC on November 27,1996 (Ref. 2),

.s GENERAL INFORMATION '

1.2 DECOMMISSIONING OVERVIEW The Plan will describe the objectives, activities, and controls that will apply to the: )

decommissioning of the WTR. The ultimate objective is to terminate the TR-2 License. To 1 accomplish this, the following are the major decommissioning activities:  !

l

1. Remove the remaining reactor vessel internal contents, the reactor vessel, and_ the i biological shield.

2. Provide the NRC with sufficient documentation to demonstrate that license termination requirements have been met. This would include all documentation that is required for transfer of the remaining residual activity to the SNM-770 License.

Additionally, decontamination and dismantlement activities of other structures and equipment associated with TR-2 may be performed. These other activities will be performed as resources-are available and until such time as these areas are transferred to the SNM-770 License.

1.3 FACILITY AND SITE DESCRIPTION The Waltz Mill site is located approximately 30 miles southeast of Pittsburgh in Westmoreland County, Pennsylvania. The site is approximately 850 acres and is located about three miles west of the town of New Stanton between the towns of Madison and Yukon. The WTR facility is located in the northwest portion of the Waltz Mill site, north of the G Building. l l

The Waltz Mill site is operated by the Nuclear Services Division of the Westinghouse Energy Systems Business Unit. The WTR is maintained under NRC License Number TR-2 (Possession Only), encompassing the requirements of 10 CFR 50. The WTR license includes the reactor structure, reactor systems, the reactor containment building, the rabbit pump room, the sub-pile ,

room, the polar crane, the WTR portion of the transfer canal, and canal waters. j The WTR was a low pressure, low temperature, water cooled 60 MWt reactor housed in a cylindrical vapor containment structure. Since permanent shutdown in 1962, all fuel and some of the reactor internal contents have been removed from the reactor vessel and from the Waltz Mill site. The reactor vessel has been drained of all water and the vessel head is secured on the vessel. The Site, including the WTR facility, has been extensively characterized and is controlled to not pose a threat to the health and safety of the site worker or the general public.

CHOICE OF DECOMMISSIONING METHOD AND DESCRIPTION OF ACTIVITIES SECTION 2 CHOICE OF DECOMMISSIONING METHOD AND DESCRIFFION OF ACTIVITIES 2.1 DECOMMISSIONING METHOD Decommissioning, as described in this Plan, will be accomplished by removal and disposal of the remaining reactor vessel internal contents, the reactor vessel, and the biological shield. The balance of the WTR facility components and the remaining residual radioactivity will be transferred to the SNM-770 License. There are no radiologicallimits applicable to the transfer of structures, materials, and equipment to the SNM-770 License, other than the radioactive 1 materials possession limits specified in the SNM-770 License. Prior to the transfer, the SNM-770 License will be amended as necessary to include the remaining WTR associated radioactive

. material inventory. Additionally, any other document revisions required as a result of this

. transfer will be performed. Future use of these structures, materials, and equipment shall be j appropriately maintained in accordance with the SNM-770 license conditions and site procedures i controlling occupational and public exposure.

The WTR facility is only part of the Waltz Mill site and the TR-2 non-power reactor license essentially forms a regulatory " island" on the SNM-770 site. The entire site, including the remaining WTR facility, will eventually be decommissioned and the SNM-770 License terminated. It is considered prudent and reasonable that, following decommissioning activities, the remaining residual radioactivity be transferred to the SNM-770 License.

Precedent for transferring the residual radioactivity to the SNM-770 License has already been established by Amendments Numbers 3,4, and 6 to the TR-2 License. These Amendments transferred previous WTR facilities to the SNM-770 License (Truck Lock Building, Process Building, and WTR Basins).

2.2.1 DecommissioninF Objectives The objective of this Decommissioning Plan is to remove the TR-2 reactor vessel internal  ;

i '

contents, the reactor vessel, and the biological shield, to the point where remaining structures are clearly not a " reactor" anymore, and then request transfer of the remaining residual radioactivity and WTR facilities from the 10 CFR 50 license to the SNM-770 License. Westinghouse would

• then request termination of the 10 CFR 50. Decommissioning will be by removal, dismantlement, decontamination, release of clean items and disposal of contaminated waste.

Dismantlement and decontamination may also be performed on other equipment and structures  ;

2 within the containment building as resources permit.  !

I 2.2.2 Decomminianing Activities ,

The general activities needed to complete the Plan objectives are:

• . Remove the remaining reactor vessel internal contents, the reactor vessel, and the biological shield.

• Prepare the decommissioning generated material for release or disposal; either

decontaminate and release as non-radioactive waste, or package for transport as radioactive waste. 1 1 . Ship all radioactive waste off-site to a licensed waste processor or disposal facility. In the event that no acceptable licensed disposal facility is available, waste may be retained j or, after processing, returned to the site for interim storage.

• Define the residual radioactivity remaining and prepare the necessary amendments to the

( SNM-770 license.

l . Request transfer of the remaining residual radioactivity and WTR facilities to the SNM-l 770 License.

• Request termination of the 10 CFR 50 license.

]

l

, The Plan will include examples of decontamination techniques, equipment and materiais which may be used, a schedule, special training requirements for workers, radiation protection and occupaticaal safety and health practices. Selection of decommissioning methods will be heavily infic.snced by worker and public ALARA considerations. A list of WTR facilities, planned t remedial activities and estimated worker exposure (person-rem) will be presented in Table 2-1.

i

, Work plans will address issues such as asbestos or other known hazards in the work areas. The decommissioning methods will utilize the most economical means to minimize the volume of hazardous, radioactive and mixed waste in consideration of ALARA. For cost-effective

! decommissioning, contaminated equipment, materials, etc., may be decontaminated, allow' mg l release for unrestricted use, or packaged for transport and processing or disposal at a licensed l

sequence of activities.

De Plan will provide a description of each of the areas covered by the TR-2 License. I The Plan will address removal of the reactor vessel internal contents, the reactor vessel,= and the '

i biological shield. Additionally, the Plan will address the required decommissioning for each area listed in Table 2-1. l 2.2.3 Decommissioning Methods i s

i Decommissioning methods are et on the area to be remMintM, the type and extent of l radionuclides, and the decommissioning objective. Contaminated areas will fall into one or more i

't of the following categories for decommissioning:

1.- Remove and dispose of as radioactive waste  ;

.2. Decontaminate for unrestricted release  !

I Each WTR area will be evaluated to determine the best method for decommissioning. Criteria to be considered in the evaluations include: availability of a licensed disposal facility; the cost -

of decontamination versus the cost of processmg and/or disposal; radiological and occupational

hazards involved; and current or planned site operations.

Removal of structures, equipment and components can be achieved using proven  !

mechanical / thermal cutting and demolition equipment. Mechanical methods such as diamond wire cutting, saw cutting, concrete scabbling, the use of jackhammers, and machining may be .

utilized. Thermal methods such as metal cutting with an oxy-acetylene torch, plasma arc cutting, or oxy-lance cutting methods may be utilized. .;

2.2.4 Decommi==ianine Schedule l i

The WTR Decommissioning Project is currently scheduled from January 1998 to 2003. He i L project schedule assumes NRC approval of the Plan by November 1997. See Figure 2-1, entitled i j "WTR Decommissioning Schedule."

i' l Changes to the schedule may be made at Westinghouse's discretion as a result of resource allocation, availability of radioactive waste burial sites, interference with ongoing Waltz Mill j operations, ALARA considerations, the potential for depositing radionuclides on adjacent i facilities, further characterization measurements and/or temporary on-site radioactive waste storage operations.

t The WTR began operations in 1959, initially operating at a power level of 20 MWt. The WTR operated in support of commercial contracts in which various materials were inserted into the ,

. core and removed at the end of a 21-day fuel cycle. Additional capabilities, such as the rabbit i facilities, allowed specimens to be inserted into the core and withdrawn during reactor

- operations, iMt of the 21-day fuel cycle.

l During the operating life of the WTR, a core disruption occurred in April,1960. Over the six months following this event, repairs and modifications were made and the reactor was returned to service in December 1960. De WTR was permanently shut down in March 1%2 3.1.2 Current Radialonical Statue of Facility Following fint.1 shutdown of the WrR in March 1%2, all spent fuel was removed from the site and shipped to Idaho. Unirradiated fuel (new fuel in storage) was returned to vendors, and

!- irradiated specimens were returned to experimenters or disposed of as radioactive waste. He

! reactor facility was partially dismantled, but not completely decontaminated. Some of the l equipment and tooling was left in the transfer canal and reactor internals remained in the pressure ,

vessel, ne reactor head was reinstalled and secured in accordance with standard procedures.  ;

The vessel and primary coolant system were drained and filterud ventilation (pr.ssive) was  ;

established. All doors were sealed or secured to prevent unauthorized entry.  !

l During 1993, a complete radiological characterization of the remaining WTR structures and components was conducted. He primary objective of this effort was to provide sufficient

, radiological information to develop the WTR Decommissioning Plan and support realistic cost i benefit analysis to assess decontamination and decommissioning options.

I l Numerous measurements and samples were obtained and analyzed to characterize the extent of  ;

neutron activation, the radioactivity present on the internal surface of components, piping, etc.,

and the extent of fixed and transferable radioactivity present on internal and external surfaces of the WTR structures and systems. This included the radioactivity present in the WTR transfer canal water, in the canal sediment, and on the surfaces of the canal walls and components / materials present in the transfer canal. l i

j De Decommissioning Plan will provide a summary of the radiological characterization of major l- WTR structures and systems.  ;

I l 3.2 RADIATION PROTECTION PROGRAM 1 i 'Ihe responsibility for the site radiation program rests with the Radiation Safety Officer and Radiation Safety Committee, as established for the SNM-770 license.

1 The Waltz Mill radiation protection program will ensure that all activities conducted within radiologically controlled areas during the Facility Decommissioning Project comply with -

regulatory requirements. Radiological hazards will be monitored and evaluated on a routine basis to maintain radiation exposures and the release of radioac+ive materials to unrestricted areas as far below specified limits as reasonably achievable.

l The radiation protection program will be integrated into all decommissioning project work activities, and each element of the program will be defined and implemented by approved policies, procedures and guidelines.

The Waltz Mill Radiation Protection (RP) Manual describes the essential elements of the

program. It provides the responsibilities, authorities and qualifications, administrative policies, 4

program objectives and standards to implement the radiation protection program. Included in the RP manual is the commitment of management to incorporate ALARA principles and philosophy into all radiological work activities. This commitment will ensure that the occupational radiation exposures for individual and collective doses and the releases of radioactive effluents are F ALARA.

s Established health physics (HP) procedures will provide guidance for performing specific tasks and the application of methods used to maintain a radiologically safe working environment. HP procedures specify the types ofinstrumentation and the methods to be employed when performing surveys and obtaining samples. Examples of typical HP procedures for surveillance include:

• Radiation, surface and airborne radioactive material surveys

• Identification and posting of radiation, high radiation, surface and airborne radioactivity i areas

!

• Access controls for radiation, high radiation, surface and airborne radioactivity areas

• Hot particle area posting and control i

. Protective clothing selection, issue, donning and removal

• Protective clothing collection, claming, survey and reissue '

i

• Personnel radioactivity monitoring ud decontamination ,

[

• Radiological protection incidents and reports 4

• Radiation protection smveillance, ey aation and assessment programs  ;

The decommissioning project may involve work activities which are not normally performed l during site operations at Waltz Mill. To ensure the current Waltz Mill radiation protection program is adequate to protect the health and safety of the workers during the decommissioning project, a review of the current program has been performed. As necessary, program l enhancements will be implemented prior to the start of decommissioning activities. l 3-2 REVISION 0

. i PROTECTION OF OCCUPATIONAL AND PUBLIC HEALTH AND SAFETY j 3.3 RADIOACTIVE WASTE MANAGEMENT This section addresses the technologies, equipment, and procedures to be implemented for the management of radioactive waste during the project. These technical approaches are based upon experience and address facets of planning, decontamination, packaging, storage, transportation, j volume reduction or beneficial reuse, and final disposition of the waste materials, while minimizing secondary wastes (i.e., wastes created by decontamination or dismantlement activities) and radiation exposure.

In developing the radioactive waste management program, the following elements will be considered:

• Location and availability of disposal facilities

• Potential for off-site release during decommissioning operations

• Preventing contamination of uncontaminated areas Use of existing facilities to support the waste packaging operations Methods of approach related to waste type, waste class, and impact on safety

. Cost effectiveness Logical approach to decommissioning operations

• Ensuring that the occupational exposures are maintained ALARA Minimizing the impact on the health and safety of the general public Maintaining flexibility for waste management to allow for unexpected wastes and changes in available technology

• Minimization of radioactive waste

. Quality Control On-site packaging or processing of radioactive waste will be performed in designated areas.

Except for lead shielding, no sources of mixed waste have been identified. To reduce or avoid the generation of mixed wastes, project management will control the use of any chemical or other  ;

substance that could become a mixed waste concern.

l If mixed wastes are generated during decommissioning, they will be classified and stored on-site until declassified or disposed. These materials will be managed according to Subtitle C of RCRA, while assuring consistency with NRC handling, storage and transportation regulations.

The details of the radioactive waste management program will be provided in the l Decommissioning Plan.

PROTECTION OF OCCUPATIONAL AND PUBLIC HEALTH AND SAFETY 3.4 ACCIDENT ANALYSIS The Decommissioning Plan will include analysis of a postulated credible decommissioning MMt scenario (s) considered to produce worst-case consequences to offsite individuals. The

, scenario (s) will be selected such that consequences bound those that could be associated with expected decommissioning conditions, off-normal occurrences, and decommissioning accidents.

De quantity of radioactivity postulated to be released will be documented, along with dose  !

consequences. The objective of the bounding decommissioning accident analysis is to show that decommissioning of the WTR facility and areas can be accomplished with no threat to the general public.

PROPOSED FINAL SURVEY SECTION 4 PROPOSED FINAL SURVEY The WTR decommissioning activities will result in the removal of the reactor biological shield, vessel and internal components. Also, decontamination and dismantlement activities of other structures and equipment associated with TR-2 may be performed under the provisions of the WTR Decommissioning Plan. After removal of the reactor vessel internal contents, the reactor '

vessel, and the biological shield, all remaining residual radioactivity and WTR facilities will be transferred to the SNM-770 License where it will be addressed by the SNM-770 Remediation Plan. Upon completion, no materials covered by the 10 CFR 50 license will exist.

The method for determining that the WTR facility has met the decommissioning objectives and prerequisites for license termination will be an independent verification that the reactor vessel internal contents, the reactor vessel, and the biological shield have been removed.

l SECTION 5 i

FUNDING Westinghouse has established one Financial Assurance Mechanism that encompasses all of the Westinghouse facilities that hold NRC licenses. The FinnMel Assurance Mechanism established by this approach meets all the requirements of the NRC's decommissioning financial assurance regulations contained in 10 CFR 50. Appropriate updates have been submitted to the NRC to maintain adequate levels of financial assurance.

In March of 1996, Westinghouse submitted to the NRC a revision to the Financial Assurance Mechanism for Decommissioning its NRC licensed facilities (Ref.1). This submittal addressed the Westinghouse Test Reactor, NRC License Number TR-2. This submittal was reviewed by

~ the NRC staff and found to be in compliance with the regulations (Ref. 2).

TECHNICAL AND ENVIRONMENTAL SPECIFICATIONS SECTION 6 <

TECHNICAL AND ENVIRONMENTAL SPECIFICATIONS 4 .

4 nis section of the Decommissioning Plan will identify the technical and environmental specifications appropriate for the WTR decommissioning. The WTR technical specifications will 1 be consistent with 10 CFR 50.36(c)(6), which provides for case-by-case development of technical specifications for non-power reactors that are not authorized to operate.

Limiting conditions for operation and surveillance requirements will be identified for any equipment or facility features rehed upon in the Wt analyses provided in Section 3.4. The

. Applicability of any such requirements will be defined to be "self-deleting" as remediation activities progress. This self-deleting feature permits surveillance or inspection actions to be discontinued after they are no longer needed, without having to revise the technical specifications.

l

, Administrative controls in the current Waltz Mill site materials license, SNM-770, will be adopted or adjusted as appropriate for WTR remediation activities. Current administrative 4 controls include provisions for:

• Review Committee membership and responsibilities

• Procedure and program requirements

• Radiation protection program requirements .

• Effluent release controls

• Radioactive waste management

Environmental monitoring and sampling requirements will be identified, consistent with the current program for the Waltz Mill site. Current requirements are identified in materials license SNM-770'. This program periodically monitors the air, water, soil, sediment, and other representative environmental samples. This section will identify any changes in environmental i measurement frequency, sample location, or sample type that may be required as a result of WTR decommissioning activities.
