With regards to matters discussed in sections 6.1 and 6.2 of the enclosed in-
spection report, we are concerned about the apparent untimely notification and
reporting of the potential problems with the 4160 volt fast bus transfer
scheme. That problem was determined to be reportable on November 27, 1989 as
a result of a reportability evaluation form initiated on October 20, 1989. We
note the comprehensive analysis and assessment of the problem by your corporate
,
engineers. However, it appears that the discovery of the condition occurred by
July 6,1989, when engineering reviews were completed sufficient to conclude
that there was a real, albeit low, probability of an event.
Our inspector discussed these concerns with your station management and was
told that a similar issue was noted by Northeast Utilities management and was
being addressed.
You are requested to respond to this concern.
Please submit
to thi', office, within thirty days of the date of this letter, a written state-
ment or explanation in reply, including; (1) your assessment of when the fast
transfer problem should have been reported and (2) the steps which have or will
be taken to assure the timely notification and reporting of events or condi-
tions as required by 10 CFR 50.72 and 10 CFR 50.73.
The response directed by this letter and the accompanying Notice is not subject
to the clearance procedures of the Office of Management and Budget as required
by the Paperwork Reduction Act of 1980, PL-96-511.
Your cooperation with us in this matter is appreciated.
Sincerely,
