qs> some doubt about the Commission's sincerity in promoting con- struction of reactors by industry. Mr, w.urray referred to the probable completion of the Shippingport reactor in 1957-t:ree years after construction began-aad said he vould like the stalf to consider the feasibility of establishing 1960 as completion date for third round reactors. Vir. Vance suggested that it might be more desirable to consider establishing a deadline for commencing the con- struction of reactors under the third round rather than a completion date, He pointed out that some reacters can be constructed in three years while others will take five years to construct. The Commissioners requested that the staff consider establishing both a deadline for commencing construction of reactors and a deadline for their compietion as well as the earliest feasible dates for these deadlines. Mr, murray then said he believed it would be advisable to include in third round contracts an option under which AEC may purchase the plant if it were not proceeding satisfactorily. Mr, Strauss requesied that the staff include consideration of this suggestion in their study. The Commissioners then approved in principle and as revised by the above discussion, the proposals set forth in AEC 152/74 for the nuclear power program. 7.
