in depth, and test temperatures ranged from 32 to 196$sup 0$F. Flaws in the test vessels ranged from 1.20 to 5.30 in.
All the eight vessels tested were loaded to failure by internal hydraulic pressure. The cylindrical regions of the test vessels were fabricated from either A508 class 2 forging steel or A533, grade B, class 1 steel plate. = ,Įight 6-in.-thick 39-in.-OD steel pressure vessels containing carefully prepared and sharpened surface cracks have been tested to provide an improved quantitative basis for evaluating the safety margins against fracture of nuclear reactor pressure vessels.
