Dear Mr. Williams:
SUBJECT:
FORT ST. VRAIN - LICENSEE EVENT REPORT 86-017
We have followed the events reported by you in Licensee Event Report (LER)
No. 50-267/86-017 submitted by your letter dated May 3, 1986 (P-86349). This
LER was subsequently evaluated by Oak Ridge National Laboratory (0RNL) under
contract to the NRC Office for Analysis and Evaluation of Operational Data.
We have reviewed ORNL's evaluation and concluded that these events raise
concerns about the sensitivity of Fort St. Vrain's helium circulation system to
off-site grid transients. A copy of our preliminary safety evaluation on these
events is enclosed.
As a result of our preliminary evaluation, the staff concludes that a more
formal review of your actions to resolve this problem would be desirable.
Therefore, you are requested to provide us with a status repo:t on actions
taken to correct the problems reported in LER No. 50-267/86-017. This status
report should address the concerns raised in our preliminary evaluation and be
provided within 60 days of the date of this letter.
The information requested in this letter affects fewer than 10 respondents;
therefore OMB clearance is not required under P.L.96-511.
Sincerely,
Original signed by
