Dear Mr. Kirsch:
Response to NRC Notice of Violation
Your letter of July 19, 1985 forwarded Inspection Report 85-16 and a Notice

Response to Notice of Violation
!
Violation B
10 CFR 50 Appendix B, Criterion V, and the Trojan Nuclear Plant Nuclear
'
Quality Assurance Frogram, Section 5.0, require in part that activities
,
affecting quality be prescribed by and accomplished in accordance with
l
documented procedures.
Plant safety procedure PS-3-30, " Trojan Holdout and Tagging Procedure",
!
Section VIII requires that when a clearance is released, the person
assigned to remove the danger tag shall ensure that the system is
'
returned to service and the tag removed and returned to the control
,
operator.
.
i
Contrary to the above, on June 28, 1985, danger tag number 4 of
'
clearance 85-1066 was on a drain valve off the "B" train. containment
spray header downstream of the containment penetration. The tag was
j
shown as cleared on the clearance sheet that had been filed in the
released clearance file.
,
t
This is a Severity Level IV violation.
Response
'
l
he o
caus was e o e error
Pla t S e y P ocedu e PS 3 30
requires that the person removing a clearance return the system to
service, remove the danger tags, and return the tags to the Control
,
Operator, who destroys them. However, when tags are cleared in con-
taminated areas, they are not returned to the Control Operator, but are
'
disposed of locally and the Control Operator informed that this has
occurred.
l
The operator who removed the clearance was interviewed and is confident
that he removed the tag on the drain valve off the "B" train Containment
'
spray header as part of releasing the clearance. This action was further
,
substantiated by a second operator who independently checked the system
i
lineup for other reasons during the same time period.
Since the tag was
potentially contaminated, the operator clearing it did not return it to
the Control Operator, but instead disposed of it in the Containment with-
out destroying it.
Based on interviews with Plant operators, it appears
that the tag was removed, but inadvertently dropped or discarded in the
i
vicinity of the valve. Other personnel passing through the area probably
}
noticed the tag and incorrectly replaced it on the valve. A review of
,
j
past practices has not identified any similar events or other problems
.

with the tagging program. Nevertheless, to help prevent future occur-
'
rences, PS-3-30 has been changed to provide personnel with specific
directions to destroy tags that cannot be removed from radiological
controlled areas when releasing a clearance.
In addition, the " Ready-for-Startup" valve lineup program was reviewed to
determine if it would have identified this problem. By the procedure,
following a refueling outage, valve lineups have been performed on all
locked valves and also on systems that have been in unusual operating
lineups or have undergone major maintenance activities. The Containment
Spray System had not met this criteria and did not receive a complete
prestartup valve lineup. As a result of this finding, the policy for
performing startup valve lineups was changed, and now valve lineups are
completed on all safety-related systems. A complete valve lineup was
performed on the Containment Spray System and several other systems. No
other discrepancies in valve position or clearances were identified.
In
the future, it will be required that valve lineups are performed on all
safety-related systems prior to startup from an extended outage.
All the above-identified corrective actions have been completed, and full
compliance with Plant procedures and programs has been achieved.
