Carolina Power & Light Company NOV 2 51985 SERIAL: NLS-85-177
. Director of Nuclear Reactor Regulation Attention:
Mr. D. B. Vassallo, Chief Operating Reactors Branch No. 2 Division of Licensing United States Nuclear Regulatory Commission
' Washington, DC 20555 BRUNSWICK STEAM ELECTRIC PLANT, UNIT NOS.1 AND 2 DOCKET NOS. 50-325 & $0-324/ LICENSE NOS. DPR-71 & DPR-62
- REQUEST FOR LICENSE AMENDMENT MECHANICAL VACUUM PUMPS
Dear Mr. Vassallo:
SUMMARY
In accordance with the Code of Federal Regulations, Title 10, Parts 50.90 and 2.101, Carolina Power & Light Company (CP&L) hereby requests a revision to the Technical
~ Specifications (TS) for the Brunswick Steam Electric Plant, Unit Nos. I and 2. The proposed change relocates a footnote from item 1.c.1 of Table 3.3.2-1 to item 1.c.1 of Table 4.3.2-1 to ensure that required surveillance testing of mechanical vacuum pumps is identified.
DISCUSSION Currently, footnote d from item 1.c.1 of Table 3.3.2-1 indicates that upon receipt of the high radiation trip signal from the main steam line, the mechanical vacuum pumps are tripped. The proposed amendment deletes footnote d from Table 3.3.2-1 and adds it to item 1.c.! of Table 4.3.2-1 to indicate that surveillance testing is required to verify the main steam. line high radiation trip of the mechanical vacuum pumps. In addition, the foonote has been revised to include verification of the mechanical vacuum pump line valve closing.
SIGNIFICANT HAZARDS The Commission has provided standards for determining whether a significant hazards consideration exists (10 CFR 50.92(c)). A proposed amendment to an operating license for a facility involves no significant hazards consideration if operation of the facility in accordance with the proposed amendment would not: (1) involve a significant increase in the probability or consequences of an accident previously evaluated; (2) create the possibility of a new or different kind of accident from any accident previously evaluated; or (3) ~ involve a significant reduction in a margin of safety. Carolina Power & Light Company has determined that:
(1)
The requested amendment does not involve a significant increase in the probability or consequences of an accident previously evaluated because relocating the footnote from the LCO table (Table 3.3.2-1) to the surveillance table
-(Table 4.3.2-1) does not require the modification or revision to any plant configuration, system function, operating parameters or setpoints.

Mr. D. B. Vassallo
- Pa~ge 2 (2)
The requested amendment does not create the possibility of a new or different kind of accident than previously evaluated for the same reasons as already discussed by item (1) above.
(3)
The requested amendment does not involve a significant reduction in a margin of safety. The proposed TS does not change any surveillance testing requirements; it only clarifies and highlights the need for verifying that the mechanical vacuum pump will trip and the mechanical vacuum pump line valve will close on main steam line monitor high radiation isolation signal during the surveillance test for the main steam line radiation monitor. Therefore, the margin of safety is maintained.
Based on the above, CP&L has determined that the proposed change meets the criteria of 10 CFR 50.92(c) and, therefore, does not involve significant hazards consideration.
ADMINISTRATIVE INFORMATION The proposed Brunswick-1 and Brunswick-2 TS pages are provided in Enclosures 1 and 2.
Carolina Power & Light Company has evaluated this request in accordance with the provisions of 10 CFR 170.12 and has determined that a license amendment application fee is required. A check for $150 is enclosed in payment of this fee.
