Dear Mr. Check:

MEETING

SUMMARY

POR CLINCH RIVER BREEDER REACTOR PLANT (CRBRP) NUCLEAR STEAM SUPPLY SYSTEM (NSSS) COMPONENT DEGRADATION MONITORING MEETING.

NOVEMBER 8, 1982 The CRBRP project and the Nuclear Regulatory Commission staff held discussions on the component degradation monitoring program. The project committed to a component degradation monitoring program, which includes a loose parts monitoring system. contains a listing of CRBRP project commitments on component degradation monitoring; Enclosure 2 is the meeting attendance list; and is the meeting agenda and the meeting handouts.

Sincerely.

SUMMARY

  • AS A RESULT OF THE LPM DISCUSSIONS WITH THE NRC ON FEBRUARY 24,1982, THE PROJECT UNDERTOOK A DETAILED REVIEW OF THE PLANT C

SYSTEMS AND COMPONENTS 4-

  • THE REVIEW INDICATED THERE WAS A POTENTIAL FOR GENERATION OF LOOSE PARTS
  • THE PROJECT DETERMINED IT WOULD BE BENEFICIAL TO INCLUDE A COMPONENT DEGRADATION MONITORING PROGRAM IN THE CRBRP

~

~

  • THE REVIEW ALSO INDICATED THAT DUE TO i

LOWER FLUID VELOCITIES, DETECTION CRITERIA WOULD NEED TO BE DEVELOPED FOR CRBRP-1
