SUBJECT:
RELIEF REQUEST FOR APPROVAL FOR THE USE OF ALTERNATE EXAMINATION REQUIREMENTS FOR THE CALLAWAY PLANT INSERVICE INSPECTION PROGRAM (TAC NO. MA5219)
Dear Mr. Randolph:
By letters dated March 19 and June 18,1999 (ULNRC-03988 and -4055), you submitted a relief request for approval of Altemate Examination ISI-12A in accordance with 10 CFR 50.55a(a)(3) for the 1989 Edition of ASME Section IX, IWA-5242(a). The relief request is for Class 1 bolted connections inside the bioshield at Callaway Plant, Unit 1 (Callaway) for the remainder of the current 10-year inspection interval (Interval 2). The scope of the request was limited to components inside the bioshield. The letters provided the hardship and unusual difficulty due to unnecessary man-rem exposure that would be incurred by removing insulation inside the bioshield on systems borated for the purpose of controlling reactivity. The relief request was approved previously for refueling outage 9 for Callaway in the staff's letter of March 24,1998.
You stated that the projected dose from the radiation levels inside the bioshield to the personnel that would be involved in the visual VT-2 examination of bolted connections for components inside the bioshield is more than 5.8 person-rem which you considered excessive relative to the smallinspection effort. You have proposed an alternative to the requirement of removal of insulation for visual VT-2 examination of bolted connections during system pressure test of components.
The staff has determined that compliance to the applicable Code would result in hardship or unusual difficulty without a compensating increase in the level of quality and safety. Therefore, the proposed alternative is authorized pursuant to 10 CFR 50.55a(a)(3)(ii) for the current inspection interval 2 for Callaway. A copy of the related safety evaluation is enclosed.
Sincerely, (Or'iginal Signed by)
