Gentlemen:
Subject:
Special Inspection 50-213/85-15 (June 14-26, 1985)
This inspection of the Haddam Neck Plant reviewed the circumstances and corrective
actions related to your identification of design change control deficiencies in
Plant Design Change Request (PDCR) No. 713, Process Computer Replacement, and to
the potential inoperability of control room fire protection equipment caused by
this ongoing modification.
The findings were discussed with Messrs. E. Mroczka
and R. Graves of your staff.
The inspection identified Violations related to the design review and safety
evaluation for the process computer replacement project, and to the onsite review
committee review of these modifications.
Please reply to these matters in accor-
dance with the enclosed Appendix A.
We note that inadequate attention to detail at several levels of the aesign review
process appears to have been a factor in the violations cited in this inspection.
We also note that your corrective action after identification of design review
process failures in the process computer modifications may not have been prompt
enough to prevent recurrence of similar violations and that your response to the
reported inoperability of three control room smoke detectors failed to promptly
restore those detectors to a fully operable condition.
We fully recognize that
your subsequent evaluation concluded that your original classification of detector
inoperability was conservative, and that the control room fire detection system
actually remained operable.
Nevertheless, your actions based on the best informa-
tion available at the time could have resulted in a needlessly prolonged period
of system inoperability.
Consequently, in addition to your reply to the violations
noted above, please include your evaluation of the effectiveness of your corrective
action programs in these instances and any further measures you have planned or
completed to improve your performance in this regard.
Your cooperation with us is appreciated.
Sincerely,
,0riginal Signed By i
