Occurrence Date:

1/10/77 e 12/28/76 Facility:

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

No. 11 and No. 12 Boric Acid Storage Tanks Inoperable.

CONDITIONS PRIOR TO OCCURRENCE:

Operational Mode 5, Reactor Power 17.5%, 85 mWe, Plant Pressure 2235 psig, Plant Temperature 552°F.

DESCRIPTION OF OCCURRENCE:

On 12/28/76, the Chemistry Foreman reported that No. 11 and* No. 12 Boric Acid Storage Tank sample analysis for boron concentration to be 19,946 ppm and 19,968 ppm, respectively.

These values being be-low the minimum concentration o~ 20,100 ppm as specified in Technical Specifications L.C.O. paragraph 3.1.2.8, the Shift Supervisor imple-mented Technical Specifications action statement for L.C.O. 3.1.2.8.

The Operations Department batched one batch of boric acid and had the Chemistry Department resample.

The results indicated No. 11 at 20,335 ppm and No. 12 at 20,281 ppm.

Technical Specifications action statement was cancelled.

DESIGNATION OF APPARENT CAUSE OF OCCURRENCE:

The cause of this occurrence was personnel error in analyzing the boron concentration of the Boric Acid Storage Tank.

ANALYSIS OF OCCURRENCE:

_Improper sampling analytical techniques declared the Boric Acid Storage Tanks inoperable.

Batching and resampling verified proper Boron concentration in No. 11 and No. 12 Boric Acid Storage Tanks.

At no time was there any hazard to the general public or site per-sonnel.

CORRECTIVE ACTION:

All Chemistry personnel were re-instructed on sample techniques and procedural instructions which requires duplicate analysis to be per-formed.

FAILURE DATE:

This is the third report of this type.

Equipment indentification not applicable.
