Dear Mr. Shelton:
This refers to the inspection conducted by Messrs. J. F. Smith, M. P. Huber
and G. D. Replogle of this office on April 19 through 29, 1993. The
inspection included a review of activities for your Davis-Besse Nuclear Power
i
Plant. At the conclusion of the inspection, the findings were discussed with
'
those members of your staff identified in the enclosed report.
The areas examined during the inspection are identified in the report.
These
areas consisted primarily of a review of the Davis-Besse Nuclear Power Plant's
program for inservice testing of pumps and valves established in response to
Generic Letter 89-04 and of the activities regarding the performance of check
valves. Within these areas, the inspection consisted of a selective
examination of procedures and representative records, observations, and
interviews with personnel.
No violations of NRC requirements were identified during the course of this
inspection.
As discussed in Paragraph 2.b.(4) of this report, an unresolved item was
identified regarding the test acceptance criteria for the auxiliary feedwater
pumps. The acceptance criteria did not appear to include margin to account
for gage inaccuracies and allowable differences in flow settings. This issue
is of concern because the testing is used to demonstrate the operability of
the pumps. With respect to this concern, we request that you respond in
writing within 30 days of the date of this letter.
This respanse should
,
address corrective actions taken to resolve the matter and any impact on
)
previous tests.
In accordance with 10 CFR 2.790 of the Commission's regulations, a copy of
this letter, the enclosed inspection report, and your response to the
unresolved item will be placed in the NRC Public Document Room.
