Dear Dr. Jens:
SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION IN FERMI 2 FSAR As a result of our continuing review of the Final Safety Analysis Report (FSAR) for the Enrico Femi Atomic Power Plant Unit 2, we have developed the enclosed requests for additional infomation.
Please amend your FSAR to comply with the requirements listed in the enclo-sure. Our review schedule is based on the assumption that the additional information will be available for our review by June 1,1980.
If you cannot meet this date, please infom us within 7 days after receipt of this letter so that 6:e may revise our scheduling.
Sincerely, 4
J n F. Stolz, Chi ight 83ter Reactors Branch No.1 Division of Project Management

130-10 130.0 STRUCTURAL ENGINEERING BRAftCH 130.7 Provide the following information regarding high density fuel storage.
1.
In Section 9C.1 it is stated that the high density spent 1
fuel and storage racks replace the original spent fuel storage racks.
Provide in a list those characteristics which affect the structural design of the fuel racks and fuel pool and their parameters, differentiating the origi-nal and the replacement design.
2.
Provide the names of the codes and standards used in the design of the fuel racks and fuel pool liner.
3.
Indicate the loads, load combinations and acceptance criteria used in the design of the fuel rack and fuel pool liner, how the fuel racks are seismically designed, and the basic considerations used in the design and con-struction of the fuel pool liner as a leaktight membrane.
4.
As a result of replacement, there is an appreciable increase in the applied load to the fuel pool concrete floor.
Indicate what modifications, if any, are to be made to the concrete fuel pool.
5.
It is stated that the storage rack structure is designed to withstand the impact from a fall weight with 2,000 FT-LB kinetic energy.
Indicate on what basis this 2,000 FT-LB kinetic energy was established, and in what position the fall weight is assumed to drop on the storage rack.
6.
Indicate if there is any possibility that the shipping cask may drop into the fuel pool and what design considerations are given to the fuel pool design.
