08-13-82 Facility:

Salem Generating Station, Unit 2 Public Service Electric & Gas Company Hancocks Bridge, New Jersey 08038 IDENTIFICATION OF OCCURRENCE:

Reactor Coolant System Chemistry - Missed Surveillance.

This report was initiated by Incident Report 82-234.

CONDITIONS PRIOR TO OCCURRENCE:

Mode 1 - Rx Power 82% - Unit Load 890 MWe.

DESCRIPTION OF OCCURRENCE:

At 1015 hours0.0117 days <br />0.282 hours <br />0.00168 weeks <br />3.862075e-4 months <br />, August 17, 1982, it was reported to the operating shift, that the Reactor Coolant System (RCS) Chemistry Surveillance due on August 13, 1982, at 1810 hours0.0209 days <br />0.503 hours <br />0.00299 weeks <br />6.88705e-4 months <br />, had not been completed until 0001 hours1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />, August 14, 1982.

The Chemistry Analyst had performed

'the other tests, but failed to perform the oxygen analysis on time.

Therefore, between 1810 hours0.0209 days <br />0.503 hours <br />0.00299 weeks <br />6.88705e-4 months <br />, August 13, 1982, and 0001 hours1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />, August 14, 1982, the conditions of Technical Specification Limiting Condition for Operation Action Statement 3.4.7a were applicable.

DESIGNATION OF APPARENT CAUSE OF OCCURRENCE:

The cause of this occurrence was oversight by the Chemistry Analyst.

ANALYSIS OF OCCURRENCE:

The limitations on RCS chemistry ensure that cerrosion of the Reactor Coolant System is minimized, and reduce the potential for RCS leakage or failure due to stress corrosion.

Maintaining chemistry within the steady state limit provides adequate corrosion protection to ensure the structural integrity of the RCS over the life of the plant.

As noted, the chloride and flouride analyses had been performed within the time specified by the surveillance requirement, only the oxygen analysis had been missed.

The oxygen analysis performed prior to this occurrence and the analysis performed at 0001 hours1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />, August 14, 1982, showed dissolved oxygen concentration to be less than 5 ppb.

J

LER 82-081/03L

ANALYSIS OF OCCURRENCE:The steady state limit for dissolved oxygen is.1 ppm or less.

The reactor coolant hydrogen concentration, which would have been depleted in the presence of dissolved oxygen, was shown to be within specification prior to and after this occurrence.

Hence, it can be assumed that dissolved oxygen concentration was below the specified steady state limit for the duration of this occurrence.

Therefore, this occurrence involved no risk to the health and safety of the general public.

As noted, chemistry was shown to be within the Technical Specification limits, however, the surveillance requirement was not performed within the time limit specified.

Therefore, this occurrence constituted operation in a degraded mode and is reportable in accordance with Technical Specification 6.9.1.9.b.

Action Statement 3.4.7a requires:

With any one or more chemistry parameter in excess of its steady state limit, but within its transient limit, restore the parameter to within its steady state limit within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or be in at least 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 />.

CORRECTIVE ACTION

As noted, the surveillance was performed and dissolved oxygen concentration was shown to be below the specified limit.

The Chemistry Supervisor counseled the analyst on the implications of this occurrence.

Written guidance was given to all chemistry analysts stressing the importance of this surveillance and its frequency requirements.

FAILURE DATA:

Not Applicable.
