20555 Gentlemen:
REVISED RESPONSE TO GENERIC LETTER 89-13, SERVICE WATER PROBLEMS AFFECTING SAFETY RELATED EQUIPMENT SALEM GENERATING STATION DOCKET NOS. 50-272 AND 50-311 Public Service Electric and Gas Company (PSE&G) responded to this Generic Letter (GL) on January 26, 1990.
Based on further review and partial implementation of committed actions, we are revising our previous plan.
Our previous plan can not be justified from a cost-benefit standpoint.
This letter does not seek approval for relaxation of previous commitments; it describes changes to our previous plan that fully meet the GL requirements.
GL item 2 required a test program to verify the heat transfer capability of all safety related heat exchangers cooled by service water.
GL Enclosure 2 describes acceptable alternate actions, such as frequent regular maintenance, for meeting this requirement.
We intend to use alternate methods when heat transfer testing is impractical due to heat exchanger design, inadequate heat load or statistical significance of test results.
Our GL response stated that "the alternative test method will require the recording and trending of important system parameters."
We are including inspection and cleaning as another alternate test method option.
Inspection and cleaning (if necessary) will be used for Room Coolers and Chiller Condensers, instead of heat transfer testing.
Our initial GL response stated that, "All of the safety-related heat exchangers cooled directly by service water will be inspected as part of the inibial test program, with the exception of the Containment Fan Coil Units (CFCU).
A sample of CFCU water boxes will be inspected during the initial inspection program."
We intend to test all CFCUs during the initial test program.
Only those heat exchangers exhibiting unsatisfactory test results will be inspected and possibly cleaned.

AUG 3 1 1990 Although not specifically stated in our initial response, we intend to inspect components included in our existing inspection program per the established schedule (i.e., this is not considered the initial test program).
Should you have any questions concerning this transmittal, please contact us.
Sincerely, C
