SUBJECT:

Calvert Cliffs Nuclear Power Plant Unit Nos.1 & 2; Docket Nos. 50-317 & 50-318 Generic Letter 83-28, Item 1.2, Post-Trip Review -

REFERENCES:

(a)

Conference call between NRC Staff ano BG&E Staff on January 6,1986, concerning Post-Trip Review at Calvert Cliffs (b)

Letter from Mr. A. E. Lundvall, Jr., to Mr. D. G. Eisenhut, dated

_November 5,1983, Generic Letter 83-28 Gentlemen:

Reference (a) was convened to permit discussions concerning the NRC Staff review of our response to Generic Letter 83-28, Item 1.2.

We informed your staff in Reference (a) that Attachment 4 to Reference (b) has been discovered to be now incorrect.

We agreed to submit an updated Attachment 4 to replace that transmitted in 1983.

Accordingly, we have enclosed an updated Attachment 4. This shows the current list of process parameters in the Technical Support Center Computer. In addition, the new attachment identifies our expected additions to the list.' Please note that the items marked with asterisks were part of the original list of inputs. The updated attachment now reflects the true status ar.d our current intentions.

We understand that with this information you will be able to closecut item 1.2 of Generic Letter 83-28.
