The areas examined during the inspection are identified in the-

observations, and interviews withLpersonnel.

The~ violation of 3 0 CFR 50,
'
Appendix B,
Criterion XI is of concern'because failure to
promptly evaluate test data could1 result.in relying on'MOVsnthat
may not function properly when called upon.
Though you_are still_
in the' process of validating your methodology for extrapolation
of test.results to-design basis conditions, you are expected to
perform an engineering evaluation of the_-test results-and VOTES
traces to look_for any anomalies-and to-determine whether enough
margin exists at test conditions to assure operability at design
basis conditions.
You are required to respond to this letter and should follow the
instructions'specified in the enclosed Notice when preparing your
'
response.
In your response, you should document ~the specific
actions taken and any additional actions you plan to prevent
