Dear Mr. Varga:
ASME CODE CASE N-133-2 SALEM GENERATING STATION UNIT NOS. 1 AND 2 DOCKET NOS. 50-272 AND 50-311 The purpose of this letter is to request, pursuant to the requirements of 10CFR50.55a(a)(3), that the NRC approve the use of ASME Code Case N-133-2 for use in the design and fabrication of replacement valves for the Salem Units 1 and 2 service water systems.
The replacement valves currently being purchased are Jamesbury Model 815L-ll-14RLMT which utilize alternate bolting material for the four bolts closest to the shaft on either valve face.
The use of alternate bolting material was approved in Code Case N-133-2 and represented the only change from Code Case N-133-1.
The use of Code Case N-133-1 has been approved by the NRC.
The replacement valves are of a more reliable design in that the use of Aluminum Bronze Alloy 954, as approved by Code Case N-133, is more resistant to erosion.
Maintenance of these valves is also easier to accomplish resulting in greater system availability.
The alternate bolting material was fabricated from Monel Alloy 400 utilizing material specification SB-164.
This material combines the mechanical and material properties necessary to assure structural integrity and limit galvanic corrosion.
For these reasons, PSE&G believes that the requirements of 10 CFR 50.55a(a)(3) have been satisfied and that the use of ASME Code Case N-133-2 is acceptable.
