l Although your emergency core cooling systems generally satisfy our requirements with regard to long-term cooling, the system configurations have not been specifically evaluated to show that significant changes in chemical concentrations would not occur during the long tem after a loss-of-coolant accident (LOCA) and these potential changes have not been specifically addressed by appropriate operating procedures.
Accordingly, you should review your system capabilities and operating procedures to assure that boron precipitation would not compromise long-term core cooling capability following a LOCA. This review should consider all aspects of your design including component qualification in the LOCA environment in addition to a detailed review of operating procedures. You should examine the vulnerability of your design to single failures that would result in any significant boron precipitation.
You should submit this evaluation and associated operating procedures within 30 days of receipt of this letter. These procedures should be promptly effected to assure that boren precipitation would not interfere with the ability of your facility to confom to Criterion (5) of 10 CFR 50.46(b). We will inform you as to the acceptability of your evaluation and associated operating procedures.
While solute concentrations may be subject to control through operating procedures, equipment modifications may be required or desirable to simplify such procedures. Your submittal should include a plan for completing such modifications within six months of the date of this letter.
This request for generic infomation was approved by GAO under a blankt.t clearance No. B-180225 (R0072); this clearance expires July 31, 1977.
Sincerely, l
