Public Service Electric and Gas Company P.O. Box 236 Ha.ncocks Bridge, New Jersey 08038 Nuclear Department November 22, 1982 Director of Nuclear Reactor Regulation U.S. Nuclear Regulatory Commission 7920 Norfolk Avenue Bethesda, MD 20014 Attention:
Mr. Steven A. Varga, Chief Operating Reactors Branch 1 Division of Licensing INOPERABLE COMPONENT COOLING WATER HEAT EXCHANGER NO. 2 UNIT SALEM GENERATING STATION DOCKET NO. 50-311 The No. 22 Component Cooling Water Heat Exchanger (CCHX) was rendered inoperable at 0700 hours0.0081 days <br />0.194 hours <br />0.00116 weeks <br />2.6635e-4 months <br /> on November 20, 1982, due to a tube leak in the heat exchanger.
The unit was operating in MODE 1 at approximately 70% of rated thermal power.
Technical Specification 3.7.3 requires that No. 22 CCHX be returned to Operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, or the unit be placed in hot standby within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in cold shutdown within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.
The CCHX tube leakage has been repaired; but the discovery of deteriorated internals in valve 22SW127, a flow controller for No. 22 CCHX, has necessitated additional repair time.
The valve internals have been repaired and the valve is being re-installed.
It appears, however, that final reassembly and testing may not be completed such that the heat exchangers can be declared operable within the allotted 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
PSE&G therefore requests that Technical Specification 3.7.3 be amended on a one-time basis to permit operation for an additional 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> with the No. 22 CCHX rendered inoperable.
Specifically it is requested that a footnote be added to Technical Specification 3.7.3 to read as follows:

The Energy People 95*2169 (4M) 3*82
Director of Nuclear Reactor Regulation U.S. Nuclear Regulatory Commission 11/22/82 "The time for completion of repairs to the No. 22 Component Cooling Water Heat Exchanger shall be extended from 0700 hours0.0081 days <br />0.194 hours <br />0.00116 weeks <br />2.6635e-4 months <br /> on November 23, 1982 to 0700 hours0.0081 days <br />0.194 hours <br />0.00116 weeks <br />2.6635e-4 months <br /> on November 24, 1982.
If repairs are not completed by that time, the unit shall be placed in HOT STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, and in COLD SHUTDOWN within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />."
The granting of this extension poses no undue risk to the health and safety of the public, since No. 21 CCHX been determined to be operable in accordance with Technical Specification surveil-lance requirements and one exchanger is capable of removing the maximum heat removal load during normal full power operation or in hot standby mode.
Availability of only one Component Cooling Heat Exchanger affects the rate of plant cooldown, but does not affect the ability to cool down.
Further, greater than design heat removal capacity exists as actual Service Water inlet temperatures are approximately 54°F compared to design operational temperatures of 85°F.
This change involves a single safety issue and therefore is determined to be a Class III amendment.
A check in the amount of $4,000 will be forwarded shortly.
Your prompt and favorable consideration of this request will be appreciated.
Very truly yours,
