This failure is a violation of

. Technical Specification 4.LB.2. The block valves were declared inoperable until the required surveillance testing was satisfactorily *accomplished. Since. the** PORVs-** remained operable throughout the period, the health and safety of. the.

public were not

affected. . The cause of the event was personnel error. A Task Team was formed to review this and similar events, and appropriate corrective* action is being taken. This event is being reported pursuant to 10CFR50.73(a)(2)(i)(B).

fil.GNIFICANT SAFETY CONSEQUENCES AND IMPI,ICATIONS ..

The remotely operated block* valves are designed to provide*. a .

positive shut off capability should a PORV become inoperable.

The PORVs

remained operable throughout . this period; therefore, the health and safety of the public were not affected.

3.0 ~USE OF THE EVENT The event was caused

by personnel error. The Engineering Testing Department . is charged with the responsibility for preparation, coordination, and maintenance of the periodic test scheduling and tracking program for the

station.

Schedullng 1s accomplished by preparmg a master planning schedule for surveillance items for which a known frequency exists. This schedule covers testing coming* due during the following month and 1s distributed

to implementing _departments one to two weeks prior to the beginning of the. month. Also provided at this time are the individual scheduling data sheets for each NRC ""'1t> :wlA IS.S9l

sur-veillance test

which is to be performed.

Each scheduling sheet delineates the acceptable time window. during which the test: is to be .performed. After the test has been performed, the

_filk~d out sheet 1s attached to the completed test procedure and provides a means to feed back information to* the *Engi_neering Testing Department. This information

is used to update the sch,eduling and tracking program.

In this instance, a new PORV block valve surveillance pro,:;edure was prepared in December 1990. The - new procedure did n'ot appear on the January 1991 master. schedule because it was approved subsequent to the promulgation of the master planning schedule. The new procedure was not added to the January schedule. because of administrative error.

Normally, Engineering Testing also distributes a Daily Periodic Test Report - for surveillance tests with scheduled date,

fate date, and days late tabulated. This report is generated on a dail-~ basis for overdue surveillance tests and on a weekly

basis

for pending surveillance tests with an interval of quarterly or greater. Because of a management decision to change the permissible "grace period" during which a surveillance could be accomplished from +/-25% to * +25%/-0%, a maJor reprogrammrng .effort was taking place in the Engineering Testing Department. Because of this added

work load, the weekly reports were not issued from late December, 1990, until early February, 199L When the issuance of the weekly report was resum~d on February 12, 1991, it showed the PORV

block valve surveillance due on February 14. This notification faile~I to alert the department responsible for the test. The daily overdue report dated February 15, *1991 showed the test as one day overdue. Although the subsequent daily_ and weekly reports

showed the surveillance as overdue, no action was taken by the implementing department until March 7.

The block valves were declared inoperable and a one-hour action statement was entered to restore operability or clos_e the block valves and remove power (re: Technical Specification 3.1.A.6.c). The appropriate surveillance testing was performed

satisfactorily, the block valves were declared operable, and the action statement was exited.

5.0 ADDITIONAL CORRECTIVE ACTION(S}

A task team was farmed to address this missed surveillance and other recent similar events at the station.

6.0 ACTIONS TO PREVENT RECURRENCE The task team's review found that current administration of the surveillance test program was adequate and complied with station administrative directives. The Team also found that certain improvements could be made, including increased supe:rvisory involvement, strengthened scheduling and tracking practices at the departmental level, and better communications between Engineering Testing and other departments. Accordingly, departments which perform surveillance testing will be required to review their internal administrative practices and take appropriate actions to strengthen their controls over the scheduling and tracking of surveillance testing. In addition, an administrative process which will provide prompt feedback to the Engineering Testing Department upon completion of surveillance testing will be evaluated.
