SUMMARY

OF MEETING ON V0GTLE DESIGN LIVE LOAD HELD JULY 23, 1986 The staff met with the applicant and its representatives on July 23, 1986, to discuss use of 25% of the design live load in combination with earthquake loads for design of Category I structures at Vogtle. Participants are listed in Enclosure 1.

The staff and applicant discussed resolution to staff's questions which were transmitted to the applicant in a letter dated July 10, 1986. Topics of discussion included a listing of all structures for which 25% of live load was used, definitions of maximum design live load and anticipated live load, with justification for adoption of such criteria.

The applicant indicated that the following actions would be taken and submitted for staff review: (1) clarification of the FSAR definition of " design live load," particularly including definitions of " pre-fuel load live load" and the

" post-fuel load live load," (2) clarification of the FSAR table to correlate the "L" value in the table with the written definition, and (3) responding to the staff's July 10, 1986, request for additional infonnation on this subject.

The staff and the applicant also had a brief discussion on July 29, 1986, to review several calculations regarding floor panel frequency sensitivity to variations in live load magnitude. This information is summarized for the six structures of concern in Enclosure 2.
