K-Reactor Cold Standby Plan

New to Sjostrom, "K Reactor Cold Standby Plan, Revision 2," RRD-940039, dated... 

The BIO examines the hazards assodated with K-Reactor in the Cold Standby condition described in the K-Reactor Cold Standby Plan (reference 2). Tlie BIO also examines the D-Reactor and P-Reactor Disassembly Basins to ensure that die storage and handling of irradiated components in those basins and hazardous mat als in their Disassembly Areas are bounded by the analyses performed for the K-Reactor Disassembly Basin. 

The Basis for Interim Operation (BIO) document for K>Reactor in Cold Standby and the L- and P-Reactor Disassembly Barins was pr ared in accordance vrith the draft DOB standard for BIO preparatiott (dated October 16, 1993). The actives for tte BIO preparation process included hamd iden carion, hazard categorization, and a preliminary hazards analysis. These actmties, along with the review of the K-Reactor Safety Anafysis R rt (SAR), K-, and P>Reactor Technical Spedfications (TS), K-Reactor Cold Standby Plan, L-Reactor ( Id Shutdown Plan, P-Reactor Standby Plait, and other safety documents, were used to compile the BIO. 

The remaining equipment unU be deenergized, drained, laid vp, and mmntained in accordance with the K-Reactor Cold Standby Plan. Laid up equipment will not be removed unless the equipment removal is documented and readily replaceable.. Records during Cold Standby will be maintained in accordance wnth the requirements of the Cold Standby Plan. 

The K-Reactor Cold Standby Plan ef. 2-1) delineates the plant configuration to support Cold Standby. To achieve Cold Standby, sterns not required toi-support habitability or the extended storage of radionuclides will be placed in a lay-up condition. Since K-Reactor is in Cold Standby, no deliberate effort is planned to maintain plant equipment that would be required for a timely restart or to mamtain reactor process water system chemistry. The equipment is expected to deteriorate from its current condition (Ref 2-1). Equipment will not be removed or used as spare parts for other DOE complex needs until such time that DOE provides revised guidance. Records will be maintained in accordance with the requirements of the Cold Standby Plan (Ref 2-1). 

The K-Reactor Cold Standby Plan provides for the continued upkeq> of the equipment and components that will satisfy the Mowing (Ref 2-1) ... 

The latest safety documentation update for K-Reactor in Cold Standby is discussed in Section 4.0 of this BIO and-consists primarily of the K-Reactor Safety Analysis Report ef 3-5), the K-Reactor Technical Specifications (Ref. 3-6), and the K-Reactor Cold Standby Plan O f. 3-3). These documents provide for storage and handling of unirradiated fuel and irradiated components and storage and processing of contaminated moderator. The latest safety documentation for L-and F-Reactor Disassembly Basins is also discussed in Section 4.0 of this BIO. These documents consist mainly of the L- and P-Reactor T hnical Specifications, L-Reactor Cold Shutdown Plan, P-Area Standby Plan, and the Transfer Packages for 100-L and P Area Facilities. These documents provide for storage and handling of irradiated components.

The safety evaluation documents that are part of the authorization basis documents for K-Reactor in Cold Standby are the K-Reactor Safety Analysis Report (SAR) and the K-Reactor Cold Standby Plan. Tliese documents and their features are discussed below. 

In an April 19, 1993, letter (Ref. 4-10), DOE directed a change in the mission for K-Reactor from demonstrating and maintaining tritium production viabiliQr to placing K-Reactor in Cold Standby. Cold Standby is defined as that condition in which a staitup pability is maintained, but with no planned provision for restart, fri response to DOE s direction, WSRC issued the K-Reactor Cold Standby Plan (Ref. 4-11) which outlines WSRC s actions for placing K-Reactor in Cold Standby. The plan addresses the following ... 

The K-Reactor Cold Standby Plan summarizes activities required to align and maintain the structure systems, and components of K-Reactor in Cold.Standby. The plan pro des for the continued upkeq of equipment and components that are required fi)r the following ... 

Since K-Reactor is in Cold Stimdby, no ddiberate effort is planned to maintain plant equipment that would be required solely for a timely restart or to maintain primaiy system cnemistiy. The K-Reactor Cold Standby Plan does not indude provisions for a planned recovery and restaiting K-Reactor. 

The K Reactor Cold Standby Plan specifies the Conduct of Operatioa programs which will continu as-is, be Modified, or be terminated as the result of the new mission of the K>Reactor. The diteria for di shioning the programs and the results of the evaluation presented in the plan supemede a WSRC letter to DOE, dated April 13, 1993, concerning the disposition of K-Reactor programs (Ref 4 15). 

SRS has an extensive DOE Order compliance program which is part of the K Reactor Cold Standby Plan, L-Reactor Cold Shutdown Plan, ai the Transfer Pack e for lOOrP Area Facilities (Ref 5-1, 5-2, S-3). These plans consist of the following ... 

As delineated in the K-Reactor Cold Standby Plan, L-Reactor Cold Shutdown Plan, and the P-Area Standby Plan (BjtC 6-48,6-49,6-62) fire hazards were significantly reduced in Cold Standby of K-Reactor and Cold Shutdown of L- and P-Reactors due to systems being drained of flammable liquids, tranrieot combustibles being removed, and work being reduced inside K-, L-. and P-Reactors. Nonessential batteries were, removed from the areas and nonessentiai systems were de-energized. The fire patrol has been replaced by operators utilizing operator round sheets (Ref 6-63, 6-7, and 6-8). Fire protection is supported by the currently installed fire water system... 

The K-Reactor Cold Standby Plan identifies an extensive DOE Order Compliance Program at SRS. A review of the Orders applicable to K-Reactor in Cold Standby identified that WSRC is not in compliance in 17 cases and has one additional Order in which the conq>Iiance status is under assessment or is otherwise pending. There were 13 CSAs and 4 exemption requests identified which are relevant, to the L- and P-Reactor Disassembly Basins. The relevant DOE Orders in which the Disassembly Areas are not in compliance are primarily of a generic or programmatic nature. In general, these noncompliances are not judged to increase the hazard level which currently exists. In addition, they do not ... 

The K-Reactor Cold Stubby Plan discusses the environmental impact of the transition of K-Reactor to Cold Standby, lids plan is a supplemoit to aiteinative 3 of the Reactor Operations Environmental Impact Statement for continued operation of K-Reactor discussed in the Final Environmental Impact Statement (Ref 4-I4V The plan >ecifies the environmental programs and activities vridch vriU continue and the monitoiing and sampling equipment vddeh will be maintained operable in the tranrition period and during Cold Sta by. 

A K Reactor Cold Standl>y Plan (Ref 2>1) developed by Westinghouse Savannah River Company (WSRC) outlines plant configuration, organization staffing, sutvdllances, environmental controls, emergen pr aredness, radiolo cal characterization, security, safety, and habitability activities required to achieve Cold Standby. 

At the Savannah River Site (SRS), K-Reactor b in Cold Standby lit which a startup capability is maintained, but no planned provision for restart Cold Standby operations be the continued stor and handling of unirradbted foel and hia ed components and the storage and processlng of contaminated modnator. Also, the L> and P-Reactor Disassembly. Basins will continue to store and handle irradiated conqioiMots. 

As noted in Section S.O of this BIO, K-Reactor in Cold Standby will nuiintain a startup capability but with no planned provision for restart. Cold Standby operations in K-Reactor will be the continued storage and handling of unirradiated fuel and iitadiated components and the storage and processing of contaminated moderator. L- and P-Reactor Disassembly Basins continue to store and handle irradiated components in their Cold Shutdown status. As such, the current site and reactor order compliance status is applicable to this expanded use.
