New Fuel Elements - Inspec t ion After I r r a d i a t i o n

Proposals have been received from two vendors. Since detai ls of method of opera t ion w i l l a f fect the complexity of the equipment, the s u b j e c t of a s u i t a b l e compromise between c o s t and convenience w i l l be more fully explored w i t h the vendor af ter the order i s placed . New Fuel Elements - Shipping Casks

The r a i l r o a d c a r requirements f o r shipping long casks were d i s - cussed with the SRP and SROO t r a f f i c departments, I n view of . the concentrated load of over 70 tons, it has been concluded that l25-ton well-type cars should be used. It is e x p e c t e d , t h a t t h e - r a i l r o a d s w i l l supply these cam, of which the ACL'now has two on order .

I n view of the c a r capaci ty , the p o s s i b i l i t y of shipping the casks immersed i n tanks of water is being inves t iga t ed . There would be a fre3ght saving estimated to exceed $200,000 a year with Mark VI-A elements, s ince the casks could be f u l l y loaded with 50 elements versus an average of only 30 elements w i t h a i r - cooled casks, There would a l s o be a reduct ion i n the requi red number of casks. Freight f o r Mark V I would be a l i t t l e greater i n the water-immersed case because even air-cooled casks can be f u l l y Loaded w i t h Mark V I .

The hazard of melt ing f u e l i s somewhat greater f o r a water- immersed cask i n the event of an acc ident i n which the cask fa l l s on i t s side o r upside down, s ince i n t h i s case pressure from b o i l i n g could cause rapid loss of water from the cask. With the cask upright, l o s s from b o i l i n g would be slow enough t o a l low 24 hours o r more f o r emergency measures before danger of melt ing f u e l , The p e r t i n e n t f a c t s and f i g u r e s have been presented t o the AEC f o r recommendation, Meantime, the cask i s being designed with f i n s for a i r cooling, and quota6ions w i l l be requested both with and without f i n s .
