Dear Mr. Reed:
SUBJECT:
NRC INSPECTION REPORT 50-237/91032; 50-249/91035
This ref e~s to the special safety inspection conducted by
Ms~ V. P. Lougheed and Mr. G. M. Nejfelt of this office on
October 28 through November 12, 1991.
During this inspection,
we evaluated activities at your Dresden Nuclear Power station,
Units 2 and 3, as authorized by NRC Operating Licenses
We discussed our findings and
conclusions with Messrs. J. Kotowski and L. Gerner, as well as
others of your staff, at the conclusion of the inspection on
November 12, 1991..
Areas examined during the inspection are identified* in the
report.
This inspection specifically examined the events
surrounding the faiiure of the.local leak rate test for
containment drywell purge valve 3-1601-24.
Additionally, your
local leak rate testing program was reviewed.
Within these
areas,- the inspection consisted of selective examinations of
. procedures and representative records, interviews with personnel,
and observation of activities in progress.
Based on the results of this inspection, one apparent violation
was identified and is being considered for escalated enforcement
action in accordance with the "General Statement of Policy.and
Procedure for NRC Enforcement Actions" (Enforcement Policy) ,
.10 CFR Part 2, Appendix C (1991).
The apparent violation
involved the inoperability of containment isolation
valve 3-1601...;24 during the last operating cycle on Unit 3,. from
February 11, 1990, until September 8, 1991.
During this time
period, the valve was required to be operable by Technical
Specification 3.7.D.
The root cause of the valve being*
inoperable was due to a maintenance error which occurred during
valve operator work the previous operating cycie.
This
maintenance error was not discovered at
~AA2030117 911127

the time because a local leak rate test was not performed
following the maintenance.
The failure to prescribe and perform
a local leak rate test as part*of the post-maintenance testing
was partially due to the use of *informal communication between
the maintenance groups and the local leak rate test group as to
when these tests were required.
Accordingly, no Notice of Violation is presently being issued for
this inspection finding.
Please be advised that the number and
characterization of apparent violations described in the enclosed
inspection report may change as a result of further NRC review.
You will be advised by separate correspondence of the results of
our deliberations on this matter.

apparent violation is required at this time.
