! Technical Specification.6.4.1 riquiraa ths station b2 opsrated and maintained in f

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 sloop. isolation valve for-the decay heat removal system, to open on demand from its 4
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.
3)
' Corrective steps which have'been taken and.the results achieved:
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.
