Introduction

- A meeting was held at the request of the Department of Energy (DOE) at Silver l

Spring, Maryland, on February 18, 1987, concerning the proposed shipment of the Shippingport Reactor Yessel.

Discussion

]

I The staff met with the DOE to dis ing for the shipment of the Shippingport Reactor Yessel and'N r

ank from Shippingport, PA to Hanford, WA. The package will weigh approximately 930 tons and is about 17.5 t

feet in diameter by 43 feet long andGNdG00Nily would be transported by barge.

The decay heat load would be less than 100 watts.

The bottom of the reactor vessel is dished and the neutron: shield tank exter.ds i

slightly above' tis ' location of the fuel assemblies. The-reactor vessel will J

be: transported without fuel. assemblies present.-

'A one-inch thick lifting skirt has been added and welded around the upper j p section of the reactor vessel between the outer neutron shield tank and the top p'

lifting beam' configuration. The reactor-head is held in place by'20 short head l

1 bolts and.16 long (6-inch diameter) bolts extending from the sidefof the reactor, through; the reactor vessel lid to the lifting beam conffirJration.'

~7 f The entire package would contain about 6,500 ci of Co-60, Fe-55 and Ni-63.-

~

(.

Almost(all.the material is activation products in the thermal shield, core

' barrel,'and filler plates. No fissile or fission products are present.. Total

.)

surface contamination is about 7.2 ci of Co-60. Attempts. to remove the surface contaminaticd were only possible with electro-polishing. Basically, all J

1 radioactive material is non-dispersible.

3 There was'some q'uestion as to whether the package would be classified LSA Type A.or a Type B package.- In either case, the package should be shown to I

meet the general and normal conditions of transport.. The staff suggested that t.

model testing and analysis be used to demonstrate the adequacy of the packaging.

1 Escape of radioactive material.is not considered significant due to the

.i nondispersibility of the contents. ' More information is needed to assess the a

significance of external radiation.

DOE intends to submit an application for this package later this-year. The application would include the acceptance tests, maintenance program and operating procedures for the package.

Our initial' review would require between 3 and 4 months.
