SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT NO.120 TO FACILITY OPERATING LICENSE NO. OPR-72 1
FLORIDA POWER CORPORATION, ET AL.
CRYSTAL RIVER UNIT NO. 3 NUCL EAR GENERATING PLANT DOCKET NO. 50-302 INTRODUCTION By letter dated June 12, 1989, Florida Power Corporation (FPC or the licensee) requested an amendment to the Technical Specifications (TS) appended to Facility Operating License ho. DPR-72 for the Crystal River Unit No. 3 Nuclear Generating Plant (CR-3). The proposed amendinent would allow the licensee to use an improved method to calculate containment leakage rate.
EVALUATION The CR-3 TS on containment leak rate testing are intended to duplicate the requirements of Appendix J to 10 CFR Part 50.
On November 15,1988,. Appendix J was revised to allow an alternative method, known as the Mass Point Method, to calculate containment leakage rate.
The Mass Point Method involves calculation of air mass at various times, and the plotting of mass against time. A linear regression line is then plotted through the mass-time points using a least sqbares fit.
The sitpe of this line is divided by its intercept, and the result is multiplied by an appropriate constant to obtain leakage rate. This method has been incorporated in a new ANSI standard (ANSI /ANS-56.8-1981) and has been reviewed and approved by the Commission.
The CR-3 TS refer to containment leakage rate testing by methods in use before the approval of the Mass Point Method. Specifically, they require testing in accordance with ANSI N45.4-1972. Therefore, in order to reflect the current 10 CFR Part 50 requirements, the TS must be revised such that references to this older ANSI standard for leakages testing are removed. This change will not relieve the licensee of requirements to comply with applic6ble regulations.
It will simply allow the use of an additional methodology that has been incor-porateo into the regulations for general industry use.
SUMMARY
Based on our review, the changes proposed in this request are adequate and acceptable.
