Septs ber :5, 1979 Page three Revisions :o PGE-lC20 are :ot inte:ded to include detailed infor:2:1on af the type provided in response to NRC Staff questions, but only to assure tha: POE-1020 re:21:s consistent with all such infor=atioc, as well as vi:h any 1:for:ation developed during refine =ent of design and cc:structica details.

We expect to sub=it both PGE-1020 and our answers to NRC Staff ques-ti:ns as exhibits a: the Phase II hearing, as we sub=itted eqtfivalen:

docu=ents as exhibits at the Phase I hearing. Although we are applying our best effo rt to assure that PGI-1020 and the answers to NRC S:aff questions are fully consisten:, it is our intent tha: the answers to :he NRC S:aff cues: ions govern in the unlikely even: that any inconsistencies inadverten:ly arise.
