The surveillance requirements applicable to lower voltage circuit breakers provide assurance of breaker reliability by testing at least one representative sample of each manufacturer's brand of circuit breaker. Each manufacturer's molded case and metal case circuit breakers are grouped into representative samples which are then tested on a rotating basis to ensure that all breakers are tested.
If. wide variety exists within any manufacturer's brand of circuit breakers, it is necessary to divide that manufacturer's breakers into groups and treat each group as a separate type of breaker for surveillance purposes.

SUMMER NUCLEAR STATION TECHNICAL SPECIFICATIONS Description of Amendment Reauest The Virgil C. Summer Nuclear Station (VCSNS) Technical Specifications (TS) is being revised to remove TS 3/4.8.4.2, MOTOR OPERATED VALVES THERMAL OVERLOAD PROTECTION AND BYPASS DEVICES,pertheguidance of the improved Westinghouse Standardized Technical Specifications. The proposed TS change request (9. 30R) will remove the Limiting Condition for Operation, the Surveillance Requirements, and Table 3.8 2; and will also revise the Bases for Electrical Power Systems.
The intent of the surveillance tests in TS 3/4.8.4.2 is to assure the operability of the motor operated valves (MOVs) thermal overload protection and/or bypass devices.
This specification details the activities addressed by FSAR Appendix 3A to comaly with Regulatory Guide (RG) 1.106, " Thermal Overload Protection for Electric IEotors on Motor-Operated Valves", and is a repetition of material contained in plant procedures. Additionally, activities of this specification are not presented in the improved Westinghouse Standardized Technical Specifications. Therefore, the removal of this section will be consistent with the Nuclear Regulatory Commission and industry efforts to simplify TS. The removal of Table 3.8-2 is also consistent with actions described in Generic Letter 91-08, " Removal of Component Lists from Technical Specifications".
The Bases for this TS (Bases 3.4.8.4) is being revised to remove the discussion on MOV thermal overload protection and/or bypass devices.
Safety Evaluation The proposed amendments to TS 3/4.8.4 involve no substantiative changes to SCE&G s commitment in FSAR Appendix 3A to comply with RG 1.106, only format l
changes due to its relocation from TS to plant procedures.
The periodic testing required by RG 1.106, which is currently in TS Surveillance Requirements 4.8.4.2, will be maintained and controlled in plant procedures.
4 Additionally, the list of MOVs with thermal overload protection and/or bypass devices currently in Table 3.8-2 will be maintained and controlled in plant i
procedures. Continual surveillance will ensure that the reliability of these components are maintained.
Pursuant to the above information, the proposed TSCR does not involve a reduction in margin of safety since the changes do not have an adverse impact on containment 4
integrity, systems or components important to safety or any other desi There is also no un, reviewed safety question involved with the TSCR. gn feature.

SUMMER NUCLEAR STATION TECHNICAL SPECIFICATIONS Description of Amendment Reauest The Virgil C. Summer Nuclear Station (VCSNS) Technical Specifications (TS) is being revised to remove TS 3/4.8.4.2, MOTOR OPERATED VALVES THERMAL OVERLOAD PROTECTION AND BYPASS DEVICES, per the guidance of the improved Westinghouse Standardized Technical S?ecifications. The proposed TS change request (TSCR) will remove the Limiting Conc.ition for Operation, the Surveillance Requirements, and Table 3.8-2; and will also revise the Bases for Electrical Power Systems.

Therefore, the removal of this section will be consistent with the Nuclear Regulatory Commission and industry efforts to simplify TS. The removal of Table 3.8-2 is also consistent with actions described in Generic Letter 91-08, " Removal of Component Lists from Technical Specifications":
The Bases for this TS (Bases 3.4.8.4) is bein g revised to remove the discussion on MOV thermal overload protection and/or bypass c evices.
Basis for No Significant Hazards Consideration Determination South Carolina Electric & Gas Company (SCE&G) has evaluated the proposed changes to the VCSNS TS described above agamst the Significant Hazards Criteria of10 CFR 50.92 and has determined that the changes do not involve any significant hazard for the following reasons:
1.
The probability or consequences of an accident previously evaluated in the FSAR is not significantly increased.
The removal of TS 3/4.8.4.2 from TS in no way impacts the accident analysis of the FSAR. Compliance of10CFR50, as aaplies to Regulatory Guide 1.106, will be maintained and controlled throu
' ant procedures with changes evaluated through 10 CFR 50.59 rather than throu amendments. Therefore, the probability or consequences of a previously ev uated accident has not been increased.
- ' ' Document Control D:sk AttachmentIII TSP 940007 RC.95-0184 Page 2 of 2 2.
The possibility of an accident or a malfunction of a different type than any previously evaluated is not created.
The proposed TSCR does not necessitate physical alteration of the plant nor changes
~
in parameters governing normal 11 ant operation. Therefore, the change does not create the possibility of a new or c ifferent kind of accident or malfunction.
3.
The margin of safety has not been significantly reduced.
The removal of TS 3/4.8.4.2 and Table 3.8-2 will not diminish the existing thermal 1
overload protection and/or bypass devices operability and testing requirements.
They will be maintained and controlled in plant procedures, and changes will be subject to 10 CFR 50.59 review. Therefore, the margin of safety has not decreased.
Pursuant to 10CFR50.91, the preceding analyses provides a determination that the proposed TSCR poses no significant hazard as delineated by 10CFR50.92.
