I* g r

When project s t a t u s was attained f o r the MSHE, it was thought desirable t o have the major components for the s a l t circulating systems made by i n d u s t r i a l fabricators who were experienced i n producing reactor components such a s nuclear code vessels, heat exchangers, reactor containment vessels, etc. Engineering drawings and specifications, welding qualification procedures, and inspection procedures were prepared which were consistent with t h i s approach. Requests for bids on the reactor vessel, rabiator, heat exchanger, and the several s a l t storage tanks were sent out t o several companies considered t o have the greatest amount of experience i n nuclear component fabrication. After these companies had reviewed the drawings and speci f i c a t i o n s , a prebid conference was held a t which representatives of these cmpanies were briefed on the properties and fabricability of INOR-8 and interpretations of the specifications were made, i f unclear t o any prospective bidder.
