Design and construction innovations relative to size, construction sequence, and testing are presented to show how they provided maximum schedule flexibility to permit the containment vessel and shield building to be built on schedule despite serious delays caused by AEC licensing hearings. These innovations consisted of: (1) sufficient additional volume to preclude field stress relieving; (2) two-stage construction permitting simultaneous erection of the steel vessel and concrete of the vessel bottom head; (3) use of sufficient winter protection; and (4) elimination of the initial bare-vessel test with a single combined integrated leak rate test and structural integrity test conducted at the end of the overall plant construction.
