Docket No. 50-344 (Control Building)
Gentlemen:
P'trsuant to the Staff's commitment to provide weekly status reports on the status of resolution of open items and completion of the Staff's Safety Evaluation Report (SER) in the referenced proceeding, this constitutes such report for the week ending November 9, 1979.
During the past week, Staff Plant Systems Branch reviewers continued work on the revision to that portion of the SER dealing with the effects of the pro-posed modifications on safety-related systems and plant operation.
Completion of this revision is now dependent upon the filing by the Licensee of final, responsive answers to Staff questions 1-4 of September 14, 1979 and questions 1-7 of September 28, 1979, since the Plant Systems Branch review, raluation and SER revision has essentially progressed as far as is possible on the information (including draft responses to questions 1-3 of September 14, 1979 and questions 1-6 of September 28, 1979 submitted by the Licensee at the meeting with the Staff on October 18, 1979) provided by the Licensee to date.
In the structural area, both Staff structural reviewers and License structural personnel have devoted substantial time in the past week to analyses of the thin block wall problem which was briefly described in the Staff's status report of October 26, 1979 (more detailed information on that problem is being trans-mitted to the Licensing Board and parties in separate correspondence).
Speci-fically, Staff structural reviewers responsible for evaluation of the proposed Control Building modifications spent several days evaluating Licensee Event 0N 1510 072 791 060
a
. Report 79-15 which was filed on November 4, 1979 and which describes the block wall problem to the extent that the problem is understood at this time.
There were also several conference calls between the Staff and Licensee on this matter.
Insofar as the Staff was engaged in this evaluation, the continuing Staff review of the proposed Control Building modifications was impacted.
Sincerely,
' 'l,
r.
