SUMMARY
OF MEETING HELD ON AUGUST 21, 1975.WITH MARK II OWNERS AND ARCHITECT-ENGINEERS On August 21, 1975 representatives of certain of the above - named Mark II Owners, Sargent & Lundy, Bechtel, Stone & Webster, Burns & Roe, and the NRC staff met in Bethesda, Maryland. The primary purpose of the meeting was to discuss load factors and load combinations proposed by the Mark II Owners and their architect-engineers for assessing the capability of Mark II containment structures to accomunodate safety / relief valve (SRV) leads (LOCA loads are still being evaluated by G. E. and were not to be discussed.) An attendance list and copies of some of the tables and figures used in presentations made at the meeting are enclosed.
Messrs. Crawford and Bergstrom of Sargent & Lundy made presentations.
Some of the major points made were:
- 1. The SRV load is a major load which was not considered in the original design of Mark II containments.
- 2. The SRV load has been added to the load combinations, and load factors associated with other loads in the load combinations are being reassessed (and reduced where possible to allow inclusion of the SRV loads without design modifications.)

- 3. Present plans are to combine the SRV loads with the small- and intermediate-break LOCA loads but not with the large-break LOCA loads. (GE is assessing the time sequences of the LOCA and SRV loads to see if the SRV and large-break IDCA loads should be combined.)
- 4. Current philosophy is to include conservatism in the load rather than in the load factor.
Representatives of the NRC staff asked a' number of questions, many of which cannot be answered until after the Preliminary Forcing Function Report is completed and design assessments are made of individual containment designs.
The Mark II owners were advised not to allow the schedule for submittal of required information to the NRC staff to begin to slip. They were also advised that reductions in the margins presently included in the design of the containments or in the conservatism presently included in the load factors and load combinations presented in their PSAR's could be viewed as modifications to the principal architectural and engineering criteria for design included in their PSAR's and necessitate amendment of their construction permits.
