SUBJECT:
INSPECTION REPORT N05. 50-327/88-13 AND 50-328/88-13 - INTEGRATED
DESIGN INSPECTION FOLLOW-UP
This letter forwards the results of an inspection of the corrective actions
performed by TVA in response to the findings of the Integrated Design
Inspection (IDI) conducted in TVA's Knoxville offices between February 1 and
February 19, 1988.
During this inspection, the team reviewed both the specific
and generic corrective actions associated with the IDI findings that remained
open following our previous inspection that was documented in NRC Inspection
Report 50-327/87-74 and 50-328/87-74
It should be noted that although all
,
the IDI findings are indicated as closed, several findings involved licensing
issues which must be resolved by TVA with NRC's Office of Special Projects.
These items then are no longer considered IDI issue's and are closed only for
the purpose of this report.
IDI findings requiring resolution by the Office
of Special Projects are so indicated in the issue-specific sumaries contained
in Appendix A to the enclosed report.
In addition, for many of the IDI findings
a substantial portion of the corrective actions has been deferred by TVA until
after the restart of Sequoyah Unit 2.
In each such instance, the NRC has
reviewed and agrees with the TVA post-restart decision for completion of
corrective action.
Such IDI findings were closed by the team by verifying
that the necessary post-restart corrective actions have been entered on TVA's
Corporate Comitment Tracking System (CCTS).
The CCTS is used by TVA to track
regulatory comitments and is being relied on by the NRC to provide an
auditable trail to assure that the corrective actions are completed in a,
timely manner.
During the IDI exit meeting on September 11, 1987, the NRC made several general
observations that were programmatic in nature.
Thes'e related to:
(1) lack of
timely implementation of changes to operating procedures resulting from design
changes; (2) lack of timely corrective action; (3) lack of system integration
and (1) weakness in the design verification process.

The NRC considers that TVA has taken responsible corrective actions to
alleviate the above programatic concerns.
However, it is not possible to
assess the effectiveness of these procedural and organizational changes at
this time. The impact of these changes depends largely on their diligent
implementation by TVA and can only be assessed after they have been implemented
for a sufficient period of time. The NRC recomends that the TVA management
periodically evaluate the effectiveness of their corrective actions to the
NRC's programatic concerns to assure themselves that the corrective actions
are being properly implemented and more importantly, are producing the desired
end results.
The NRC also recomends that TVA periodically review their CCTS
to assure that the committed corrective actions are implemented in a timely
manner.
In accordance with 10 CFR 2.790(a), a copy of this letter and the enclosure
will be placed in the NRC Public Document Room.
Should you have any questions concerning this inspection, please contact me or
Mr. Eugene Imbro, (301) 492-0954.
Sincerely,
