SUBJECT:
SOUTH TEXAS PROJECT, UNITS 1 AND 2 - FIRST 10-YEAR INTERVAL INSERVICE INSPECTION PROGRAM PLAN - RELIEF REQUEST RR-ENG-24 I
(TAC NOS. MA4826 AND MA4827)
Dear Mr. Cottle:
^
By letter dated February 24,1999, STP Nuclear Operating Company (STPNOC) submitted a request for relief from. the ASME Section XI Code Table IWC-2500-1. This table includes a requirement that a surface examination be performed on essentially 100 percent of the length of each weld of one pump casing among each group of multiple Class 2 pumps.'
The Nuclear Regulatory Commission staff has evaluated the information provided and concludes that the Section XI cxamination requirements for the subject welds are a hardship and an unusual difficulty on STPNOC without a compensating increase in the level of quality
- and safety. Furthermore, the staff concludes that STPNOC's proposed alternative and previous
)
)
inspection results provide reasonable assurance of structuralintegrity of the subject welds.
Therefore, STPNOC's proposed alternative contained in relief request RR-ENG-24 is authorized pursuant to 10 CFR 50.55a(a)(3)(ii). Our related safety evaluation is enclosed.
Sincerely, ORIGINAL SIGNED BY
- Robert A. Gramm, Chief, Section 1
