SAFETY EVALUATION FOR VIRGIL C. SUMMER NUCLEAR STATION ,

Description of amendment request:

Currently,theVirgilC.SummerNuclearStation(VCSNS) Technical Specifications Surveillance Require'nent 4.8.1.1.2. (c), " Electrical Power Systems," requires that each diesel generator be demonstrated operable "by ,

obtaining a e. ample of fuel oil in eccordance with ASTM D270-1975 at least ,

once per 92 days and prior to the addition of new fuel oil to the storage 1 tanks...." The purpose of demonstrating the operability of the diesel t generators is to ensure that sufficient power will be available to supply the safety related equipment required for 1) the safe shutdown for the facility and 2) the mitigation and control of accident conditions within the facility.

The diesel fuel oil monitoring and analyses requirements delineated in Technical Specification 4.8.1.1.2 ensure that the quality of the oil meets the NRC guidelines on kinematic viscosity, water and sediment content, and specific gravity, per Regulatory Guide 1.137, Revision 1, " Fuel Oil Systems for Standby Diesel Generators" (October 1979).

The proposed amendment revises Surveillance Requirement 4.8.1.1.2 with respect to diesel fuel oil storage, monitoring, sampling, and analysis. This-proposed change replaces VCSNS Technical Specification Surveillance-Requirement 4.8.1.1.2(c) with the corresponding requirement in NUREG-0452,

" Standard Technical Specifications for Westinghouse Pressurized Water Reactors." Additionally, the revision adds a requirement to_ check for and remove any accumulated water in the fuel oil storage tanks every 31 days.

This requirement is also contained in NUREG-0452.

The following table exhibits the differences between current VCSNS Technical Specifications and the proposed revision (NUREG-0452): l t Current VCSNS Proposed Revision Technical Specifications (NUREG-0452) l

-Page 4 of-5 Basis For No Significan t Hazards Consideration: .

The proposed amendment has been reviewed and determined to involve no' '

significant hazards consideration. Operation of the Virgil C. Summer Nuclear Station in accordance with the proposed changes to the Technical i Specifications is evaluated with respect to the criteria of 10CFR50.92 as follows: j

1. The changes would not involve a significant increase in the probability or' .i consequences of any accident previously evaluated at VCSNS. No change to '

the design or function of any plant' system is proposed. The proposed standard for diesel fuel oil acceptability will assure that, from a fuel standpoint, the emergency Diesel Generator System (EDGS) will continue to '

functiontreliably and can continue to be credited for operation in those instances presently required in the Safety Analysis. The fuel. oil surveillance-program will continue to ensure that an adequate: supply of quality fuel oil is maintained onsite.

2. The changes would not create the possibility ~of a new or different kind of accident from any accident previously evaluated. No-change'in EDGS operation or reliability will' result from the proposed change in allowable fuel properties. The proposed change is limited to the sampl_ing and

-I analysis of diesel fuel oil, anc' will continue to ensure.that the fuel oil j at VCSNS meets the fuel oil requirements specif,ied in Regulatory Guide i 1.137, Revision 1. " Fuel-011 Systems for Standby Diesel Generators" _;

(October 1979).

3. The changes would not involve a significant-reduction in a margin of safety. .A comparison between acceptability standards for Grade No. 2 Diesel Fuel Oil between ASTM 0975-77 Table 1 and ASTM D975-81 Table 1 indicates no difference. The margin of safety at the Virgil C. Summer Nuclear Station will not, therefore,.be reduced by the proposed change.

The Nuclear Regulatory Commission has provided examples of amendments that are not likely_to involve a significant hazards consideration. Example (ii).-  ;

51 FR 7751 is as follows: '

"A change that constitutes an additional limitation, restriction, or control not currently included in the technical specifications." i SCE&G has determined proposed Surveillance Requirement 4.8.1.1.2.c to be similar to example (ii) since it is an additional control to ensure the j quality of available diesel fuel oil. '

Example (i), 51 FR 7751 is as follows: '

"A purely administrative change to technical specifications."

SCE&G has determined proposed Surveillance Requirements 4.8.1.1.2.h and-4.8.1.1.2.1 to be similar to example (i) since these requirements have been changed only in the relabeling of sections and constitute an editorial change in order to achieve consistency.
