October 6. 1982 Page 1 of 3 FORT ST. VRAIN NUCLEAR GENERATING STATION PUBLIC SERVICE COMPANY OF COLORADO 16805 WELD COUNTY ROAD 19 1/2 PLATTEVILLE, COLORADO 80651-9298 REPORT NO. 50-267/82-039/03-L-0 Final IDENTIFICATION OF OCCURRENCE:

An internal audit identified several instances of nonperformance of required surveillance testing of fire barrier penetration seals which had been disturbed by System 21 modifications.

This is contrary to the requirements of LCO 4.10.4 and is reportable per Fort St.-

Vrain Technical Specification AC 7.5.2(b)3.

EVENT

DESCRIPTION

Fort St.

Vrain Technical Specification SR 5.10.4 states that " Fire Barrier Penetration Seals shall be visually inspected:

.. (b)

Immediately following any maintenance which disturbs the retardant material, to verify seal is returned to its previous condition."

The purpose of this inspection is to verify that the fire barrier penetration seals are in compliance with LC0 4.10.4 requirements.

In

addition, LCO 4.10.4 requires a

" continuous fire watch" to be posted on either side of a seal if it is disturbed by maintenance.

On October 6, 1982, during the performance of a Quality Assurance audit of Change Notices and Controlled Work Procedures, it was determined that the requirements of LCO 4.10.4 and SR 5.10.4 had not been met during and after modifications associated with System 21.

CAUSE

DESCRIPTION:

The Controlled Work Procedure Manual (CWPM) was not adequately clear in requiring that a continuous fire watch be posted during fire barrier penetration seal maintenance and that SR 5.4.10.4.b-X must be performed following such maintenance.

CORRECTIVE ACTION:

The Controlled Work Procedure Manual is to be revised to explicitly identify the requirements of LCO 4.10.4 and SR 5.10.4 in the Controlled Work Procedure planning phase.

s REPORTABLE OCCURRENCE 82-039 ISSUE O Page 2 of 3 All fire barrier penetration seals will be identified and inspected.

The " Fire Penetration Seals Annual Inspection," SR 5.10.4.A-A, will be reviewed to verify that all existing seals are included in the surveillance test.

No further corrective action is anticipated or required.
