• '[ violation- '

y ; w v. .: ~

pt  ! Technical Specification .6.4.1 riquiraa ths station b2 opsrated and maintained in f j ecordancejwith approved procedures. Operations Management Procedure (OMP).2-3.

K_-  ? Reactor' Operator' logs states that/significant. abnormalities which occur wil1~be 2notedjin thejlog': Examples include malfunction-of any equipment normally operated ifrom the control room.-.;0MP 2-2, Unit Supervisor's Log Book, states that'significant

~

cbnormalities which occur will be explained in greater detail than in the Reactor

> 0perator 's : log'.

Contrary to the above,1on: October 15, 1985, neither the Reactor Operator or Unit

Supervisor's log contained an entry discussing the failure of valve 3LP-2, the 4

sloop. isolation valve for-the decay heat removal system, to open on demand from its icontrol room handswitch.when _it was desired to place the decay heat removal system

. ?in service.g Though the valve was opened 55 minutes later and decay heat removal was

.maintainedf through the. steam generators,- failure to log the item or to write a work

)crder provided no indication to management of possibly-needed maintenance or imodification.

This' is a. Severity Level IV violation- (Supplement I) .

p

' Response

'1) Admission or denial of the alleged vioiation: --

- This violation is correct as stated; however,-the last sentence erroneously implies that management was unaware of the. problem with valve 3LP-2. An Assistant Operating Engineer was in the Control Room when the valve failed to

. operate from the switch and was aware of this failure. A station Work Request

- was issued to repair the problem.

~

(2)' ? Reasons 1for the violation-if admitted:

During past plant operations, some valves (particularly secondary system valves)-

have occassionally failed to-open immediately from the Control Room switches.

- One of the common techniques for freeing these valves from their closed seats has_been to manually override the torque switch from the breaker while operating the switch until the seats are cleared.. When this technique was necessary

. on 3LP-2 the personnel involved 'did not consider it a significant abnormality and therefore did not enter it into the log. '

' Corrective steps which have'been taken and.the results achieved:

3) 4

~ The individuals involved were counseled, including the stressing of the importance p of compliance with Operations Management Procedures concerning log entries.' The appropriate information concerning 3LP-2 was written as a late entry in the RO and SRO Logs. '

4 Corrective steps which will be taken to avoid further violations:

<>. ( 4)-

~ w' '

- a' The importance of proper' log entries has been and will continue to be stressed to

' E all licensed Operations person'nel. This will~ be accomplished through crew meetings

, . and, through- the use of :a training package on this ' subject issued for review by all ~

1:

licensed Operators.

5) - Date when full compliance will be' achieved:

Actions noted in (4) above will be completed by February 23, 1986.
