UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D,C. 2055&4001 January 13, 1995.
Hr. B. Ralph Sylvia Executive Vice President, Nuclear Niagara Mohawk Power Corporation Nine Hile Point Nuclear Station P.O.
Box 63
- Lycoming, NY 13093
SUBJECT:
NINE MILE POINT NUCLEAR STATION, UNIT NOS.
1 AND 2 (NHP-1 AND NMP-2),
APPROVAL OF CODE CASE N-498-1 AS AN ALTERNATIVE TO THE REQUIRED HYDROSTATIC PRESSURE TEST (TAC NOS.
H90232 AND H90233)
Dear Hr. Sylvia:
By letter dated August 18, 1994, Niagara Mohawk Power Corporation (NHPC) requested approved to use American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASHE Code)
Case N-416-1 in lieu of performing the Code-required hydrostatic pressure test for welded repairs or installation of replacement items by welding and ASME Code Case N-498-1 in lieu of performing the required 10-year pressure test at NMP-1 and NHP-2.
NRC approval for NHPC to use ASHE Code Case N-416-1, with certain provisions, was issued by our letter and attached safety evaluation dated October 18, 1994.
- However, as stated in our October 18, 1994, letter, the NRC staff's review of ASHE Code Case N-498-1 was incomplete at that time and, therefore, use of ASHE Code Case N-498-1 was not then approved.
The staff has now completed its review of the proposed use of ASME Code Case N-498-1 at NMP-1 and NHP-2.
Based on the information submitted, NHPC's alternative (ASHE Code Case N-498-1) is authorized pursuant to 10 CFR 50.55a(a)(3)(ii) since compliance with the specified requirements of Section XI of the ASHE Code would result in hardship or unusual difficultywithout a compensating increase in the level of safety and quality when applied to pressure testing at both NHP-1 and NHP-2.
NHPC's alternative, use of ASHE Code Case N-498-1, is authorized until such time as this code case is published in a future revision of Regulatory Guide 1.147.
At that time, if NHPC intends to continue to implement this Code
- case, NHPC is required to follow all provisions in ASHE Code Case N-498-1 with limitations issued in Regulatory Guide 1. 147, if any.
