Report Date: 12/20/77 Cccurrence Date- 12/28/76 Facility: Salem Generating Station Public Service Electric & Gas Company Hancocks Bridge, New Jersey 08038 i

IDENTIFICATION OF OCCURRENCE:

No. 11 and 12 Boric Acid Storage Tanks Inoperable CONDITIONS PRIOR TO OCCURRENCE:

Operational Mode 1, Reactor Power 17.5%

DESCRIPTION OF CCCURRENCE:

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 of 20,100 ppm as specified in Technical Specifications LCO paragraph 3.1.2.8, the Shif t Supervisor imple-mented Technical Specifications action statement for LCO 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:

Review of operating records failed to identify the cause for the apparent dilution. Chemistry records confirm the low boron concen-tration and batching results correspond to the expected increase in boron concentration.

ANALYSIS OF CCCURRENCE:

Technical Specification Action Statement "A" for LCO 3.1.2.8 states that with the boric acid storage system inoperable, restore the storage system 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 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 borated to a shutdown margin equivalent to at least li AK/K at 200*F; restore the boric acid storage system to operable status within the next 7 days or be in cold shutdown within the next 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />. The boric acid storage system was returned to operable status within the 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> allowed by LCO 3.1.2.8, therefore, Technical Specification compliance was achieved.

- .LER 76-30/03L , 12/20/77 CORRECTIVE ACTION:

l Operations Department personnel re-established the boron concentration in the Boric Acid Storage tanks and chemical analysis confirmed operability.
