SUBJECT:
FIRST TEN-YEAR INTERVAL INSERVICE INSPECTION PROGRAM PLAN - REQUEST TO USE ASME SECTION XI CODE CASE N-416-1, SOUTH TEXAS PROJECT, UNITS 1 AND 2 (STP) (TAC NOS. M98294 AND M98295)
Dear Mr. Cottle:
By letter dated March 26, 1997, Houston Lighting & Power Company (HL&P) submitted a request for approval to allow use of ASME Section XI Code Case N-416-1, " Alternative Pressure Test Requirement for Replacement Items by i
Welding, Class 1, 2 and 3,Section XI, Division 1," at STP. ASME Code Case N-416-1 allows system leakage testing at normal operating pressure and temperature in lieu of hydrostatic pressure testing for welded repairs or installation of replacement items by welding.
I The Nuclear Regulatory Commission staff has evaluated the information provided and concludes that compliance with the Codt. hydrostatic testing requirements for welded repairs or replacements of Code Class 1, 2 and 3 components would result in hardships without a compensating increase in the level of quality and safety. Accordingly, ilL&P's proposed alternative to use Code Case N-416-1 is authorized for STP pursuant to 10 CFR !.0.55a(a)(3)(ii) provided that the additional surface examinations are performed on the root pass layer of butt and socket welds on the pressure retaining boundary of Class 3 components when the surface examination method is used in accordance with Section III, as proposed.
4 Use of Code Case N-416-1, with the additional surface examination as noted above, is authorized for the duration of the current ten-year inservice s
