Company E. C. Simpson Public Service Electric and Gas Company P.O. Box 236, Hancocks Bridge, NJ 08038 609-339-1700 Senior Vice President - Nuclear Engineering OCT 2 6 1995 LR-N95165 United States Nuclear Regulatory Commission Document Control Desk Washington, DC 20555 Gentlemen:

ASME CODE CASE N-539 SALEM GENERATING STATION UNIT NOS. 1 & 2 HOPE CREEK GENERATING STATION FACILITY OPERATING LICENSE NOS. DPR-70, DPR-75 & NPF-57 DOCKET NOS. 50-272, 50-311 & 50-354 Public Service Electric and Gas Company (PSE&G) requests approval, in accordance with the requirements of 10CFR50.55a(a) (3), to use American Society Of Mechanical Engineers (ASME) Code Case N-539, "UNS N08367 (Cast Alloy CN-3MN) in Class 2 and 3 Valves,Section III, Division 1 11 (Copy Attached)_

for Salem Generating Station Unit Nos. 1 and 2 and Hope Creek Generating Station.

The use of this Code Case is not presently referenced in NRC Regulatory Guide 1.84, "Design and Fabrication Code Case Acceptability -

ASME Section III Division 1 11,

Revision 30 dated October, 1994.

Code Case N-539 provides the ANSI B16.34 requisite pressure-temperature ratings of the UNS N08367 materials, necessary for the use of this material in the construction of ASME Class 2 and 3 valves.

The UNS N08367 materials include SA-351 (Casting), SB-564 (Forging) and SB-688 (Plate).

These materials are ASME approved materials for Class 2 or 3 component construction, and have been incorporated for use in ASME Section III, Editions and Addenda and Code Cases that have been previously endorsed by the NRC.

However, prior to this code case, the UNS N08367 materials had never been assigned a pressure-temperature rating for specific use in valve construction.

The use of this material is desirable for valve construction because of its corrosion resistance properties.

Further, it is compatible with the piping materials that have been recently used in the Hope Creek and Salem Service Water System replacements.

The use of UNS N08367 materials in conjunction with the ANSI B16.34 pressure-temperature ratings per Code Case N-539 does not introduce any conditions that would compromise existing levels of safety or quality at either Salem or Hope Creek.
