SUBJECT: ENGINEERING INSPECTION AT WATERFORD 3 (NRC INSPECTION REPORT NO.
50-382/96-202)
Dear Mr. Sellman:
On October l'0,1996, the U.S. Nuclear Regulatory Commission (NRC) completed an
engineering inspection at .terford 3. The enclosed report presents the
results of that inspecti The primary objective of tha inspection was to
conduct a safety system n.actional review of the component cooling water
system (CCWS), auxiliary component cooling water system (ACCWS), and their
support systems. The inspection team also evaluated your safety assessment
and corrective action processes, design control programs and procedures, and
engineering support for the station. At the exit meeting on October 10, 1996,
the inspection team discussed its findings with you and members of your staff.
Subsequently, on October 15 and 21, 1996, conference calls were held between
members of the NRC staff and your staff to discuss issues associated with
tornado missile protection and emergency diesel generator surveillance
testing.
Overall, the team determined that the Waterford 3 engineering staff
demonstrated good technical competence and familiarity with plant operations.
However, the team noted deficiencies in the implementation of design control
programs and procedures, and weak technical evaluations in support of plant
operations. The technical evaluations or calculations to support the design
bases were not always available. In some cases, the actual design values were
inconsistent with those stated in the final safety analysis report (FSAit).
The team identified weaknesses in both original design and recent engineering
work. However, none of these issues resulted in system inoperability.
Through its walkdo,m, the inspection team identified components that may not
be protected from tornado missiles. The team was concerned that your staff
had previously identified this issue but the corrective actions did not
adequately address the conditions. This issue indicated a lack of
understanding of the design basis of the plant. We understand that your staff
performed operability evaluations for continued operation. We also understand
that you have committed to implement plant modifications to correct the /
unprotected cables and conduit installations by December 16, 1996, and to }9'
perform a comprehensive review of the design and licensing bases for tornado

missile protection for Waterford 3 by January 31, 1997. These actions are j
described in Entergy's correspondence (W3F1-96-0188) to the NRC dated
. October 21, 1996.
The 10 CFR 50.59 evaluations for the plant modifications were generally
adequate. However, the team identified examples of inadequate 10 CFR 50.59
evaluations performed in support of calculations, licensing document changes
and condition reports.
The team determined that earlier root cause and operational experience
engineering evaluations did not prevent problem recurrence. However, recent
'
evaluations were effective in identifying and correcting problems. In some
cases, followup and corrective actions for degraded or non-conforming
conditions were not always timely or thorough in addressing the problem areas.
Many good issues were identified through the safety system self-assessments of
,
the ultimate heat sink and emergency feedwater (EFW). However, the self-
assessments did not identify many of the issues raised by the team.

No response to this letter is required. The NRC Region IV Office will issue
any enforcement actions resulting from this inspection. In accordance with 10
'
CFR 2.790(a), a copy of this letter and its enclosure will be placed in the

NRC Public Document Room. If you have any questions about this inspection,
please contact the NRC Project Manager, Mr. C.P. Patel, or the inspection team
