20555 Attention:
Gentlemen:
Mr. Steven A.
Varga, Chief Operating Reactors Branch No.
1 Division of Licensing CYCLE 7 RELOAD REDESIGN FACILITY OPERATING LICENSE DPR70 UNIT NO.
1 SALEM GENERATING STATION DOCKET NO.
50-272 NFU 86-175 Salem Unit No.
1 completed its sixth cycle of operation on March 21, 1986.
During the reload, damage of a grid strap on each of two fuel assemblies was observed when the assemblies were removed from the core.
The ID' s of these assemblies are H60 and.H63.
They fell in symmetric positions in the cycle 7 design.
Two partially burned bundles CID's are F23 and F49> from the spent fuel pool replaced the two damaged bundles.
One assembly was moved to improve core symmetry.
These changes are included in the Salem Unit 1 Cycle 7 Core Loading Pattern Figure 1.
No other changes were made to the design.
PSE&G and Westinghouse made an evaluation of the loading pattern change for Cycle 7.
PSE&G concurs with the Westinghouse con-clusion that the new reload design does not change the design/
safety evaluations or conclusiqns of the original RSE.

Mr. Steven A.
Varga 6-13-86 Therefore, as previously stated in Reference 1, there are no unreviewed safety questions as defined by 10CFR50. 59 associated with the redesign for Cycle 7, and that an application for amendment to the Salem 1 operating license is still not required.

Mr. Steven A. Varga, Director PWR Project Directorate #3 Division of PWR Licensing A
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.
