NUCLEAR REGULATORY COMMIS$10N '3 of W ASHINGTON, D. C. 20555 JUN 101975 Docket Nos- 50-416 and 50-417 Applicant: Mississippi Power & Light Company Facility : Grand Gulf Nuclear Station Units 1 and 2
SUMMARY
OF MEETINGS HELD ON JUNE 3 AND 4, 1975 TO~ DISCUSS DESIGN BASIS LOADING AND DESIGN METHODS FOR THE GRAND GULF MARK III CONTAIhMENT.
A meeting was held on June 3,1975 at the Bechtel Power Corporation offices in Gaithersburg, Maryland and on June 4, 1975 at the NRC offices in Bethesda, Maryland. The purpose of the meetings was to; l) establish the capability of containment structures (including I-beams and steel gratings) to accept loads in excess of the current design specification, and 2) establish the degree of uncertainty associated with the current design load
' specification. The discussions were centered around the clarification and expansion of information presented in the applicant's April 23, 1975 Contain-ment Structures Design and Loading Report. An attendance list is provided in the enclosure.
The June 3, 1975 session was devoted to a discussion of the design methods used by the architect engineer (Bechtel) to factor suppression pool dynamic loads into the Grand Gulf containment structures design. The capability of the structure to withstand loads in excess of the current specification was j examined using revised design methods acceptable to the NRC staff. Various load combinations in addition to those presented in the applicant's April 23, 1975 Report were examined.
It was concluded that there is substantial design margin, at least a f actor I of two, in the junction between the containment foundation and the dryvell wall to accept loads induced by suppression pool swell and impact on struc-ures above the pool. The junction between the containment wall and founda-tion is not sensitive to impact loads on structures above the suppression pool.

The design of the traveling incore probe (TIP) station (approx. 6' above the pool) has no margin at present, however, the applicant indicated its inten-tion to lower the bottom of the station into the pool and thereby substan-tially reduce the loading. Wide flange beams and grantings at approximately the same elevation have some margin under conditions of plastic deformation and are capable of being strengthened.
An analysis by the applicant of the steam tunnel (approx.15' above the pool) shows that the floor could withstand a triangular load profile of 50 psid peak for 50 msec. The applicants were unable to provide an acceptable basis for the 15 psid load specified for this structure and will be required to provide an acceptable basis for the final design load or relocate the structure.
The HCU floor (approx. 24' above the pool) is supported by steel I-beams attached to the containment and drywell wall with brackets. There is approx- ,
imately a 50% design margin in the bracket design using a plastic-elastic analysis technique. The NRC staff was unable to determint. that this analysis technique is acceptable at the meeting and will require additional information.
The HCU floor design has no existing margin but is capeble of being strength-ened.
. The June 4, 1975 session was devoted to examining the design loads specified by the applicant and the uncertainties associated with the specification.
The applicant was unable to support its load specification to the NRC staff's satisfaction due to the limited test data base and uncertainties in their methods of interpreting the test data. The NRC staff was able to develop a conservative load specification for valves, pipes. I-beams, and small compo-nents and the applicant was offered the option of designing to this specifica-tion or waiting to provide additional test data to support its existing design 1 loads.
The meeting was concluded with the applicant's agreement to inform the NRC in the next several days of its intentics toi 1) Use a more conservative design load profile, or 2) provide additional test cata to support the design load profile currently being used, or 3) relocate or modify the affected structures.
