0 l0 h op ne e m. ~ _ _ __ _ =a: s ama,nm On January 16.

1986 at 1500, the Radiochemistry Department discovered that the or1 mary containment air sampling procedure dic not adecuately meet the requirements set forth in the Technical Speci f icat ionn.

The plant was in Operational Condition i

5 with the mode switch in shutdown curing an outage and all control rods inserted in the core Primary cont ainment was ooen at the time to perform plant modifications.

Plant Manacement was notified of the event and tne NRC was notified at 1437 the next day.

Technical Specification 3,11.2.1 requires that the containment air ce namoled and analyzed on a monthly basis for particulates, iocines anc noble gases.

However, in accordance with the sampling procedure, Sp74.020.04, the analysis was performcd by takinc an air samole downstream of the RMS skid (1D11*PNL-061)

I af t er cassing tnrouch a carticulate filter and a charcoal filter.

Tne samole is then placed in a Geli recorder for a

complete isotopic analycio.

Although the grab samples were

ov in and analyzed in accordance with the Tech Specs (as indicated in table 4.11.2.1.7) ttey die not fully meet the recuirements au w e the iocinec anc pa r1 I'cu l at es hac been fiitered out p'ic to the analysis.

This procedure nad been used for p r e v i o i, monthly somoling per Tech.

Spec.

3.11.2.1 and for swpling cova prior to anc curing purging ano venting as required by Tech.

Spec.

3.11.2.8.

The noble gas analysis was done au required.

Upon cisccvery of the event, grab air namples were taken and analyzed for oart i cul at es anc iodines in accordance with an approved st, tion prncedure, Sp

62. 20.01 (Airborne Activity Survey Tecnnicures ene Deteroination).

There is no safety signi ficance to tnis event, because the drywell air is continuously monitored.

Any t ime containment was purgec or vented, the air was exnausted through tne Reactor Builcing Ventilation Exhaust System (RDNVE) and was also sampled by the normal station vent monitors.

These are Particulate, Iodine and Ganeous (PIG) mon i t orn.

No abnovval readince have occurred.

The samoling and analysis was performed by radchemintry personnel in accordance with an approved station arocedure.

Sampl;ng and analysis for noble gases will remain the same, by procedure, but the station proce ure will be revised to change the method of sampling and analysis for particulates and iodines.

The existing filters (charcoal and part icu l at e) in the sample ukid will be roolaced with " grab sample" filters.

After the sample air passes throuch the filters for a specified collection time, the filters are removed and analyzed for particulaten and

iodines, ibis crocedure channe will be incorporated into t h:' procedura prior to 1

the performance of the next surveillance test as required b; the Technical Scecification.
