REQUEST FOR ADDITIONAL INFORMATION REGARDING INTERIM INSPECTION REQUIREMENTS FOR REACTOR PRESSURE VESSEL HEAD (TAC NOS. MB7752 AND MB7753)
Dear Mr. Katz:
By letter dated February 18, 2003, you responded to the Nuclear Regulatory Commission (NRC) Order dated February 11, 2003, regarding interim inspection requirements for reactor pressure vessel head. In reviewing that submittal, the NRC staff raised three groups of questions which were transmitted to your staff by a publicly available e-mail (Accession No. ML030570009). On February 26, 2003, the NRC staff held a conference call with your staff to discuss those questions and agreed that only the first group of questions (reproduced below) needed to be formally conveyed.
What is the justification that coverage up to 0.75 inches above the weld will provide an adequate level of quality and safety? In other words, provide justification that increasing the scope of inspection to 2 inches above the J-groove will not provide an increase in quality and safety. Are there residual stress data that indicates that 0.75 inches is a sufficient level above the weld, or is there any other basis that demonstrates an acceptable level of quality and safety for the restricted inspections?
Your staff indicated that you can respond on or before March 15, 2003.
Sincerely,
/RA/
