On 4-20-92, contrary to Technical Specification (TS) 4.1.2.2.a.l, the seven-day test to prove the operability of the boration flow paths from the refueling water storage tank and the boric acid storage tank was not performed as scheduled. The test is accomplished by cycling each testable power-operated or automatic valve in the flow path through at least one complete cycle of full travel. The missed surveillance was identified on 4-24-92. The surveillance procedure was immediately performed. All test acceptance criteria were met. The missed surveillance occurred as a result of personnel error during the review process.

The findings of this event were reviewed with the involved personnel by their supervisors.

Unit two (U-2) in mode six at OX power.

Descri tion of Event On 4-20-92, the 1-OHP 4030.STP.002V (Boration System Valve Position Verification and Testing) surveillance procedure was not performed to satisfy the Technical Specification (TS) surveillance requirement 4.1.2.2.a.l for TS 3.1.2.2 (Reactivity Control Systems Flow Paths - Operation). TS 4.1.2.2.a.l requires at least once per seven days that the boration flow paths from the refueling water storage tank (RWST) (EIIS/CB-TK) and the boric acid storage tank (BAST) (EIIS/CB-TK) be proven operable by cycling each testable power-operated or automatic valve in the flow path through at least one complete cycle of full travel.

The missed surveillance procedure was discovered by an Operations Department Engineer on 4-24-92, The surveillance test was last performed on 4-13-92.

The TS action statement was entered at 1255 hours0.0145 days <br />0.349 hours <br />0.00208 weeks <br />4.775275e-4 months <br /> and the 1-OHP 4030.STP.002V surveillance procedure was started, completed, and reviewed by 1314 hours0.0152 days <br />0.365 hours <br />0.00217 weeks <br />4.99977e-4 months <br /> on 4-24-92. A review of the completed surveillance noted that the surveillance acceptance criteria were satisfied and the action statement was exited at this time.

On 4-20-92, the involved Unit Supervisor (Senior Reactor Operator) reviewed the 1-OHP 4030.STP.002V paperwork completed during his shift. Following this review, the Unit Supervisor recorded the completed sections of the 1-OHP 4030.STP.002V surveillance procedure in the Master Surveillance Schedule.

While recording the completed sections of the surveillance procedure just reviewed, the Unit Supervisor incorrectly recalled that the weekly surveillance section of the procedure had been completed and signed off the weekly surveillance procedure as complete.

Following the performance of the surveillances listed on the schedule, the Operations Department Engineering Section conducts a review of the completed surveillance paperwork. During this surveillance paperwork review, the engineers identified on 4-21-92 that the 1-OHP 4030.STP.002V weekly surveillance procedure sheets were missing.

Although the engineers identified that the weekly surveillance was apparently in grace due to the missing paperwork, the engineers did not pursue further why the surveillance procedure had not been completed. This was based on the engineers'ast experience had shown that the control room operators also track incomplete surveillances and pursue the completion of a surveillance before the grace period expires.

Cause of Event The cause for the missed surveillance was personnel error. The Unit Supervisor developed a mind set during the surveillance review that the surveillance was completed and therefore signed off the surveillance procedure as complete on the schedule.

In addition, the engineers had a mind set that control room operators record and track surveillances in grace and that the control room operators were aware that the surveillance had not been completed, or that the paperwork must have been routed to the engineers and had not arrived. Therefore, the engineers did not pursue further the completion of the surveillance.

A~nal sls Technical Specification (TS) 4.1.2.2.a.l (Reactivity Control Systems Flow Paths - Operating) requires at least once per seven days the boration flow paths from the refueling water storage tank (RWST) and the boric acid storage tank (BAST) to be proven operable by cycling each testable power-operated or automatic valve in the flow path through at lease one complete cycle of full travel. The failure to perform the surveillance is a violation of Technical Specification 3.1.2.2 and is reportable under 10 CFR 50.73 (a)(2)(i)(B).

Following the identification of the missed surveillance, the 1-OHP 4030.STP.002V surveillance procedure was performed to satisfy the requirements of TS 4.1.2.2.a.l. A review of the completed surveillance noted that the requirements of the surveillance procedure were met. Therefore, it is concluded that the valves tested by the surveillance procedure would have performed their safety function if required during the time period from the last completed surveillance procedure on 4-13-92 and the surveillance procedure performed on 4-24-92.

Based upon the above analysis, the failure to perform the surveillance procedure within the grace period is not considered to have created a significant safety concern, nor did the missed surveillance create a significant hazard to the health and safety of the general public.

Corrective Action

1. Following the identification that the portion of the 1-OHP 4030.STP.002V surveillance procedure had not been performed, the 1-OHP 4030.STP.002V surveillance procedure was satisfactorily completed.
