- Part-tire Introduction A neeting was held at the request of Haste t'anagenent Group, Inc. at Silver Spring, fiaryland, on January 15, 1936, to discuss a proposed irradiated hardware cask.
Discussion Sentry Eouipment Corporation proposes to subnit to the !!RC the Fodel
?!o. S-36 cask to be used for the shipment of up to 30,000 ci of Co-60 in the form of irradiated hardware (450 thernal watts).
The stainless steel, lead shielded cask is 44.5" CD by 173".long with a 26" ID by 156" cavity. With the balsa wood inpact liniters, the overall package dinensions are 69" OD by 17'.
The inner shell is 0.6" thick followed by 6.3" thick lead, 0.8" concrete (thermal barrier),1.6" thick outer shell, and a 200 nil outer polished stainless steel surface. The lid is secured by 14,1.25" high strength bolts on a 28" bolt circle and is sealed with two silicone rubber 0-rings with a test port between the seals.

The Files '
2 tener briefly discussed the nethod of analysis of the package and Fenchworking of the calculational techniques based on 1/4 and 1/5 scale nodel test of the l'odel No. LK-100 spent fuel cask. The URC staff asked that the safety analysis report for the package address possi51e slap-down effects on the packaqe and expressed concern for the attachment of'the inpact liniters to the cask (possibility of the inpact limiters cominq off t! e cask during the 30-foot drop and puncture tests).
Sentry Equipment Corporation (a US conpany) indicated they would request approval of a previously approved 10 CFR Part 50 cuality assurance plan for the design and fabrication of packanes under the requirerents of 10 CFR Part 71.
An application nay be submitted sone tine this sunner. Our initial response would require about 3-4 nonths after the application is received.
