Inspection 50-289/85-25. '

, < ,' JDuringitheperiodfrombetober 18-25, 1985, members of the NRC TMI-l Restart e

TSt'aff conducted routine and'special-' safety inspections of operational activi-

.tiesJat.your-facility.' :The results of these~ inspections are documented'.in the '

enclosed inspection report. .'At'the conclusion of the inspection Mr.-R. Conte,

- of:myTstaff,! summarized the; inspection findings for you and other members-of_

<' [your, staff.(lOn balance, the findings were favorable. Of particular note was

'

lthe, continued ~highflevel of; performance of.the operations department-in the:

'

Juse'of"theiriskills to minimi.ze challenges to: safety systems.- However, the

.

results!in one area are of concern and' warrant our continued examination; and,-

,' '

tin another area, there was an apparent violation oferegulatory requiremente, ,

4 Of particular' concern to us'during this period were the circumstances that

a 's ' developed during and after a routine surveillance test of the pressurizer

1' +

< power operated relief valva (PORV)!during the midshift_on October 25, 1985.

The(issue's'of concern include-~(1) a: routine test that could not be completed ~ ,

7 :because-a portion of the test was:not conducted correctlyL (2) the unnecessary ,

aL Tcreation.of:both a deficiency sheet and an exception sheet as,a result of-that-

Jtestiand, subsequently,:throwingthesesheetsawayand(3)theconfusing

~ f

- _,' idocumentation#used to substantiate the shift supervisor's determination of

~

., ,

'

operability of;the -PORV. As a result of ourLwitnessing your retast, it was

'

clear-toTus within several hours that.the PORV.wasLin fact operable.throughout-

'the period except, of-course,'whileLit was'being tested. It/is'also clear to

Jus:that there was' prompt involvement by your senior management in th' retest.

.

'Our early involvement-in this process, however,' led to your discovery of the

t 1

,

'

1 exception land deficiency sheets that had been thrown away'. We are aware that

-

' ~ "the essential information on these' sheets also was'available on.other records ,

^ thatjyou had retained.  ;

Although we have no'immediate. safety-concern at this point .we are concerned.

,

' with the actions that took place.. Accordingly, we request that you provide us

1

. with a report containing your analysisiof this event. In-particular, yout-
