On October 28, 1987, representatives of the staff and NNECO met to discuss. ,

proposals for placino a post-LOCA heat removal variable and containment hydrogen concentration on.the SPDS. Enclosure 1 is a list of attendees. The' highlights of the discussion are summarized as follows:

1. The NNECO proposed that a post-LOCA heat removal variable will be 'l directly accessible from a single function key within the SPDS core cooling critical function via a plant process computer (PPC) display. 3 I

2. The NNECO proposed that containment hydrogen concentration will be 1 directly accessible from a single function key within the.SPDS containment critical safety function via a PPC display.

)

3. The staff stated that although'the proposed modifications met the license condition for these variables, the proposals.did not meet the' ,

guidelines of NUREG 0737 Supplement 1 because, as proposed, the variables I are not continuously displayed when they are available.

j
