SUMMARY

OF MEETING CONCERNING MODEL NO. MH-1A PACKAGE DESIGN Atendees NRC DOE Richard H. Odegaarden Charles Mauck Henry W. Lee Introduction g

On November 26, 1985, Department of Energy (D0E) met with the NRC staff to discuss two summaries of structural evaluations of the Model No. t1H-1 A cask.

Discussion DOE showed the NRC staff summaries of structural evaluations of the Model No. MH-1 A cask perfonned by SANDIA Laboratories and Westinghouse-Hanford. Both evaluations appeared to confinn the NRC staff position that the package seal would be lost following the accident condition of transport tests.

DOE plans to pursue the analysis with Westinghouse-Hanford. The contents of the fuel material will be taken into account including a limited amount of crude on the outside of the fuel plates and rods. The NRC staff expects a reasonable amount of success in DOE obtaining a NRC certificate for the cask.
