Dear Mr. Shiffer:
Center)
A. Singh R. Serbu R. Fell J.
Wing W. Brooks H. Gi1 pin L. Chandler J. Milhoan Your letters of January 28, 1986 (DCL-85-019 and 020) provided additional information regarding your proposed spent fuel pool reracking, as requested by the staff.
Based on the staff visit on January 27, 1986 to the Joseph Oat Company, designer and manufacturer of the spent fuel racks for the Diablo Canyon Nuclear Power Plant, we have determined that further information regarding the structural analysis is required for the staff to complete its review.
The information is identified in the enclosure.
We plan to discuss your response to our request in a meeting with you on February 20, 1986 in Bethesda, Maryland.
Sincerely,
/s/SVarga

ENCLOSURE REQUEST FOR ADDITIONAL INFORMATION DIABLO CANYON NUCLEAR POWER PLANT, UNITS I AND 2 SPENT FUEL POOL RERACKING (Continued) 26.
With respect to the computer code DYNAHIS discuss specific efforts performed to verify that the code provides realistic seismic responses of the fuel racks when subjected to a set of complex loading conditions and geometric constraints.
For example, indicate if experimental data were used as a basis for demonstrating the validity of the code.
Provide a discussion of the assumptions and limitations which are unique to the code.
27.
Selected load combination cases, relative geometries of various fuel
- racks, and directions of seismic motion were considered in the fuel rack analyses.
Discuss in detail how this approach bounds the significant cases of fuel rack load geometry conditions to ensure the structural integrity and functionality of the racks.
