On January 2, 1998, while Point Beach Nuclear Plant (PBNP) Unit 1 was operating at 98 percent power and Unit 2 was in a cold shutdown condition, Wisconsin Electric determined that five pressure tests required by the Gection XI pressure test program that had not been conducted were in fact missed surveillances. The pressure testing was completed on January 3, or prior to returning equipment associated with the tests to operable status.

The cause of the missed surveillances was inadequate procedural control to assure completion in accoraance with the requirements of the Pressure Test Program. Procedure changes will be completed to set test frequency requirements.

Event Description

^

On September 16, 1996 five ASME Section XI tests wers discovered which were not completed in accordance with the Pressure Test Program.

These were documented on a condition report (CR 96-840) at that time. As a recult of that condition report a corrective action was assigned to perform the tests prior to the end of the interval which ends for Unit 1 on November 30, 2000 and for Unit 2 on September 30, 2002.

On November 4, 1997 an additional condition report (CR 97-3730) was created to occument the operability of the systems associated with the original condition report. On January 2, 1998, while Point Beach Nuclear Plant (PBNP) Unit 1 was operating at 98 percent power and Unit 2 was in a cold shutdown condition, Wisconsin Electric determined that the five pressure tests required by the Section XI pressure test program that had been identified in 1996 were in fact missad surveillances.

The following 40 month pressure tests were not performed within the required frequency and their last completion date prior to January 3, 1998 is listed:

Functional Test of the Gol Emergency Diesel Generator Air Start System (February 7, 1990)

Functional Test of the G02 Emergency Diesel Generator Air Start System (August 17, 1989)

Inservice Test of the Waste Gas System (Deceraber 7, 1991 and September 19, 1991) i Inservice Test of the Unit 1 Boric Acid Tanks and Transfer Piping (April 1, 1987 and April 15, 1987)

Functional Test of the Unit 2 RWST and Associated Piping (September 19, 1989)

The first three of the missed pressure tests were completed on January 3.

The remainder were tested prior to returning equipment associated with the tested systems to operable statua.

Causes

The cause of the missed surveillances was inadequate procedural control to assure completion in accordance with the requirements of the Pressure Test Program.

Corrective Actionst 1.

The Functional Test of the Unit 2 RWST and Associated Piping was completed on November 6, 1997.

An operarility determination addressing the romaining systems was complete.n accord 6nce

As discussed above, after determination that the missed tests were in fact missed surveillances, the pressure testing of the following systems wara completed on January 3, 1998:

7 Functional Test of the G01 Emergency Diesel Gcnerator Air Start System Inservice Test of the Waste Gas System Inservice Test of the Unit 1 Boric Acio Tanks and Transfer Piping The last two inspections were not completed within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of determining these tests were required, and appropriate systems were dec1cred inoperable.

No Technical Specification actions r-"ded to be entered.

4.

The Functional Test of the G02 Emergency Diesel Generator Air Start System was completed on January 23, 1998.

5.

The procedures which control the frequency of those tests will be revised to include these pressure tests by June 1, 1998.

i 6.

The following procedures will be reviewed for revision to requ re the 40 month pressure testing to be performed in conjunction with IT-600, IT-17 and IT-1075 as discussed below.

These revisions or new procedures will be implemented by June 1, 1998.

Component and System Description The primary purpose of the G01 and G02 air start systems is to provide a tank with a nominal working pressure of 175 psi to the starting system for the emergency diesel generators.

Each unit has its cwn independent starting system, including two banks of three air storage tanks.

The pressure test for these systems is performed via a Preventive Maintenance / Surveillance Test "ork Order, li l

nx1 af more om os requad, vee eHmonalreques of NRC form 36eN (17) 55 The viste gas system includes the gan decay tank and associated piping.

This test has been performed in the past by a now discontinued procedure.

The pressure test on this system will now be performed once each 40 months in conjunction with IT-600, " Waste Gas System Gaseous Leak Checks ( Annual). "

The Unit 1 boric acid tanks and transfer piping pressure tast was performed by a now discontinued procedure.

The test will. tow be conducted once each 40 months in conjunction with IT-17, Boric Acid Transfer Pumps and Valves (Quarterly)."

The functional tost of the Unit 2 RWST and associated piping was conducted by a now discontinued procedure.

The test will now be conducted in accordance with IT-1075, "40 month Functional Pressure Test of Refueling Water Storage Tank Piping."

Safety Assessment

Each of the systems ic a system required for the safe operation of Point Beach or response to an accident.

The pressure test program is designed to detect any evidence of leakage.

The frequency for each test in this case was 40 months.

The most recent tests showed no evidence of unacceptable Itakage.

Therefore, there was no probability of failure of these systems to perform their safety function during the period of failure to test.

None the less each of these systems would have exhibited some dagradation during their normal Technical Specification surveillances or preventctive maintenance.

No degradation of a type which would have been specifically sought out was discovered during the Technical Specification surveillances or preventative maintenance.

Therefore the haalth and safety of the public or plant personnel was not compromised by these missed surveillances.
