Occurrence Date: 03-17-83 i . Facility:- Salem Generating ' Station Unit 2-

-Public~ Service Electric &' Gas ~ Company Hancock's Bridge, New Jersey 08038 $

JDENTIFICATION"OF OCCURRENCE:-

Missed Sample - PlantJVent Weekly Iodine--and Particulate Activity.

t Thisireport was initiated by Incident Report 83-056.

CONDITIONS PRIOR TO' OCCURRENCE:.

Mode 6 RX Power 0 Unit Load 0 MWe.

' DESCRIPTION OF OCCURRENCE:

At 1500 hours0.0174 days <br />0.417 hours <br />0.00248 weeks <br />5.7075e-4 months <br />, March.17, 1983, while conducting routine sampling-of

~

+

gaseous radioactive waste,=it was discovered that the sample pump for the-iodine / particulate collection devices-was de-energized.

Investigation revealed that the pump was supplied-by theEsame breaker  ;

as the pump for. Radiation Monitor R-41. The breaker 1had been; tagged out at 2111 hours0.0244 days <br />0.586 hours <br />0.00349 weeks <br />8.032355e-4 months <br />, March 11, 1983, for implementation ofJa-design.

. change of Monitor.R-41. Due to the'resulting inoperabilityHof the

• F collection devices, the iodine and particulate samples for the week of -i March 10.to. March 17, 1983, were not representative of-gaseous

effluents.

At 2030 hours0.0235 days <br />0.564 hours <br />0.00336 weeks <br />7.72415e-4 months <br />,- March .17,1983, a temporary power 1 feed to the collection device sample pump was installed and the pump was 3

re-energized. No detectible: gaseous releases occurred during the-interval in which the collection devices were -inoperable; c no Environmental Technical Specification (ETS) limits were exceeded.

' APPARENT ~CAUSE-OF OCCURRENCE:

Further investigation of the incident revealed that the collection device pump was not'on the list of loads'off the No. 2B West Valve and .

L Miscellaneous:230V Vital Control Center, which, supplied both-pumps.

The-fact that power.would be removed from the pump was.therefore not

apparent to the operator researching the tagging request.

ANALYSIS OF OCCURRENCE:

! Proper operation of the; plant vent iodine and particulate collection j devicesJis necessary to meet sampling requirements of-the ETS Limiting Condition for Operation 2.3.4e. The requirements provide assurance >

'that. radioactive-materials-released in' gaseous waste effluents are .

properly. controlled and monitored in accordance with plant design criteria. . Sampling data provides the basis for routine' reports and 1 evaluation of radioactive materials' released in gaseous effluents.

LER 83-004/04L ANAliSI OF OCCURRE'NCE: (cont'd)

Information obtained from daily analysis'of data'from the Plant Vent Monitor 2R16 substantiated that no detectible release of radioactive

material: occurred during-the period in question. The occurrence-

-therefore involved no adverse impact on :the environment.

Section15.4 of- the ETS requires:

If a limiting _ condition for operation is exceeded, remedial action-as-permitted by.the.ETS shall be taken until the condition can be' met, an investigation shall be conducted by the SORC, and a report shall be submitted.in accordance with ETS Section 5.6.2.

CORRECTIVE ACTION:

L As noted, an alternate power feed to the coll'ection device sample pump was provided. Daily surveillance of the pump will be conducted.until the normal' power source is restored. Completion of an LER and the SORC review of the document comply with-the requirements of ETS Section 5.4. An estimate of the radioactivity-released based on

-similar weekly samples will lue made to include in the composite data

,i for the routine effluent report, in compliance with the specification.

The incident will'be addressed in a weekly Operations Department directive, to insure that operators are aware that the breaker also' feeds the collection device and that the device is necessary for ETS sampling requirements. The Tagging. Request and Inquiry System will be revised to print'out a note directing notification of the Chemistry Department when the breaker is tagged open. . Finally, the problem will be addressed as-part of a broader Operations Department effort to provide additional information on panel and breaker loads. This effort is-currently in progress; Engineering Department assistance with implementation will'bo provided as necessary.
