Dear Mr. O'Reilly:

LICENSE NO. DPR-70 DOCKET NO. 50-272 REPORTABLE OCCURRENCE 76-21/3L Pursuant to the requirements of Salem Generating Station Unit No. 1 Technical Specifications, Section 6.9.1, we are submitting Licensee Event Report for Reportable Occurrence 76-21/3L. This

• report is required within thirty*(30) days of tJ;ie occurrence.

Sincerely yours, p~

Report Number: 76~il/3L Report Date: 1.6/76 Occurrence Date: 12/10/76

!tacility -Salem Generating Station Public Service Electric & Gas Company .

Hancocks Bridge, New Jersey 08038 IDENTIFICATION OF OCCURRENCE:

Boron Injection Tank. Inoperable.

CONPITIONS PRIOR TO OCCURRENCE: .

• Mode 3 operation, Plant pressure 2235 psig, Plant temperature 547°F.

pESCRIPTION OF OCCURRENCE:

On 12/10/76; at 5:45 AM, the Chemistry Technician reported the Boron Injection Tank sample analysis for boron concentration was 19~899 ppm.

This value*is below the minimum concentration of .20,100 ppm as specified in Tech Spec L.C.O. paragraph 3.5.4.l(b). The Shift Supervisor imple-mented Technical Specification Action Statement for L.C.O. paragraph 3.5.4.1 and requested additional samples be taken and analyzed. At 10:00 AM,* on 12/10/76, the Chemistry Technician reported the re-analysis indicated the Boron Injection Tank boron concentration was 20,540 ppm.

Technical Specification Action Statement was cancelled.

DESIGNATION OF APPARENT-CAUSE OF OCCURRENCE:

Personnel error in analyzing the boron concentration of the Boron Injec-tion Tank. . The Chemistry Technician did not run a duplicate analysis as stated in the procedur~ to verify the first sample analysis.

ANALYSIS OF OCCURRENCE:

Improper sampling analytical techniques declared the Boron Injection Tank inoperable. SuQsequent sample analysis verifieq proper boron concentra-

. tion in the Boron Injection Tank. At no time was there any hazard to the general public or site personnel.

CORRECTIVE ACTION:

The Chemistry Technician was re-instructed on sample analytical tech-niques and procedural instructions which requires duplicate analysis to be performed. ...

FAILURE DATA:

This is the second failure of this type.

EVEN! DESCRIPTION (Continued)

~

• l and requested additional samples be taken and analyzed. At 10:00 AM, on 12/10/76, the* Chemistry Technician reported the re-analysis indicated that the Boron Injection Tank boron concentration was 20,540 ppm. Technical Specification Action Statement was cancelled.

The Boron Injection Tank is a passive component common to both ECCS subsystems and therefore, no redundant component exists. This is the second occurrence of this type. (76~21/3L).

CAUSE DESCRIPTION (Continued) instructions to perform duplicate analysis.
