Cp&L Carolina Power & Light Company SERIAL: NLS-85-403 MAR 'l 71986 Director of Nuclear Reactor Regulation Attention: Mr. Dan Muller, Director BWR Project Directorate #2 Division of BWR Licensing United States Nuclear Regulatory Commission Washington, DC 20555 BRUNSWICK STEAM ELECTRIC PLANT, UNIT NOS.1 AND 2 DOCKET NOS. 50-325 & 50-324/ LICENSE NOS. DPR-71 & DPR-62 REQUEST FOR LICENSE AMENDMENT REACTOR COOLANT SYSTEM LEAK DETECTION INSTRUMENTATION

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 of the Technical Specifications (TS) for the Brunswick Steam Electric Plant, Units I and 2. The proposed revisions delete reactor coolant system leakage detection instrument tag numbers that are not part of the equipment used to monitor reactor coolant system leakage.

DISCUSSION The requested TS changes delete Tag Numbers G16-FY-K600 and G16-FY-K602 from the instrumentation tag numbers associated with (1) the primary containment sump flow integrating system referenced in TS 4.4.3.1.b and (2) the drywell and equipment drain sump flow system referenced in TS 4.4.3.2.a. Tag Numbers G16-FY-K600 and G16-FY-K602 specify square root converters that only provide an input to a flow recorder. These square root converters do not provide an input to the sump monitoring systems encompassed by the TS referred to above. The flow recorder is not used to satisfy the TS requirements for containment sump flow monitoring (i.e., reactor coolant system leakage detection), therefore, the flow recorder is not listed in the TS. Since the square root converters are not associated with indicators or recorders required by the TS, the tag numbers associated with these components should be deleted from the TS.

SIGNIFICANT HAZARDS ANALYSIS The Commission has provided standards for determining whether a license amendment request involves a significant hazards consideration (10 CFR 50.92(c)). A proposed amendment to an operating license involves no significant hazards consideration if op)eration of the facility (f involve a significant in accordance increase with the in the probability or proposed consequences amendment would not 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 reviewed the changes enclosed in accordance with 10 CFR 50.92 and determined that the requested amendment does not: \

Mr. D. Muller Prge 2 fp ,

1. Involve a significant increase in the probability or consequences of an accident previously evaluated because the deletion of the tag numbers for the square root converters does not affect the operability of containment sump monitoring equipment required by the TS. These square root converters only provide an input to recorders which are not required by the TS.

2. Create the possibility of a new or different kind of accident than previously evaluated because the proposed changes will not modify or alter an existing. plant system. The proposed changes simply delete references to tag numbers for components that are not associated with recorders or indicators required by the TS.

3. Involve a significant reduction in the margin of safety because the proposed changes do not affect the operability or setpoints of existing equipment required by the TS nor the capability to monitor containment sump flow for detection of excess reactor coolant system leakage.

The proposed changes are administrative revisions to delete the tag numbers for the square root converters. Based on the reasons above, CP&L has determined that the proposed changes involve no significant hazards consideration.

ADMINISTRATIVE INFORMATION The proposed Brunswick-1 TS pages are provided in Enclosure 1; the proposed Brunswick-2 TS pages are provided in Enclosure 2. Carolina Power & Light Company has evaluated this request in accordance with the provisions of 10 CFR 170.12 and determined that a license amendment application fee is required. A check for $150 is enclosed in payment of this fee.
