e Pubhc Service Electric and Gas Company Thomas J. Mariin 80 Park Plaza, Newark, NJ 07101 201430-8316 Mailing Address: P.O. Box 570, Newark. NJ 07101 Vica President Engineering and Construction August 18, 1983 Dr. Thomas E. Murley, Administrator U.S. Nuclear Regulatory Commission Office of Inspection and Enforcement Region I 631 Park Avenue King of Prussia, Pennsylvania 19406

Dear Dr. Murley:

NRC IE BULLETIN NO. 83-05, DATED MAY 13, 1983 "ASME NUCLEAR OODE PUMPS AND SPARE PARTS MANUFACTURED BY THE HAYWARD TYLER PUMP COMPANY (HTPC)"

HOPE CREEK GENERATING STATION The subject NRC Bulletin has been reviewed by our Engineer-ing and Hope Creek Operations Departments. The information and actions noted below apply only to the referenced safety related pumps or spare parts that were manufactured by the HTPC between 1977 and 1981 inclusive.

The answers listed below correspond to the numbers in the bulletin.

la. Attachment 1 is a list of affected ASME code pumps and service applications.

Ib. As the Inservice Testing Program (IST) is developed, the NRC's concerns and the HTPC expanded commissioning and inspection requirements (Attachment 3), including the 48 hour5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> endurance test, will be addressed in the appropriate IST's and individual Detail Test Proce-dures (DTP's) for the referenced pumps.

The Inservice Inspection (ISI) requirements for HCGS safety related pumps are being developed per the guidelines and requirements of ASME Section XI, 1977 Edition with Addenda through the summer 1978. Spe-cific tests and test requirements are outlined in the Hope Creek Pump Data Sheets being developed by South-west Research Institute (SWRI).

Ltr. to Dr. T. E. Murley 8/18/83 lc. Public Service has committed to performance tests in the Hope Creek FSAR. Attachment 2 compares these with the NRC recommended tests. The comparison shows three (3) deficient areas; pump to motor alignment, manual shaft rotation, and pump temperature checks. The latter two items will be incorporated as outlined in the Hayward Tyler test procedure (Attachment 3). For the pump to motor alignment we take exception to the tolerance of .002 inch. The tolerance should be based on the type of coupling used and the motor speed. The tolerances and procedures outlined in the instruction manuals and the 13th edition of The Hydraulic Insti-tute Standards will be followed when performing the pump to motor alignment.

Id. General requirements and procedures for the hydro-static testing of system piping are contained in Specification 10855-P-590(Q), " Technical Specification for Hydrostatic Testing of ASME Section III and ANSI B31.1 Piping Systems" and in Specific Work Plan / Pro-cedure SWP/P-P-4, " Leak Testing of Piping Systems" (available at the HCGS job site). Detailed test pro-cedures in the form of marked up drawings and test report forms will be prepared and implemented at the time of the test operation.

2a. The Maintenance Procedures for HCGS which will address the HTPC expanded commissioning and inspection requirements (Attachment 3) and installation of replacement parts (Attachment 4) are:

MD-CM.ED-001(Q) - Fuel Pool Cooling Pump Overhaul and Repair.

l MD-CM.GB-002(Q) - Chilled Water Circulation Pumps Overhaul and Repair.

M D-CM . BC-00 3 ( Q ) - HTPC ECCS Jockey Pump Replacement, Overhaul and Repair.

2b. See item lb for inservice test requirements.

l 2c. See Item Ic for performance test requirements.

2d. See Item ld for plan of ASME Code System pressure test.
