Analysis of ASME Boiler, Pressure Vessel, and Nuclear Components in the Creep Range

Maan H. Jawad, PhD, is President of Global Engineering and Technology in the United States, a firm that offers engineering consulting to the pressure vessel, power, petrochemical, and nuclear industries. Previously, he served as Director of Engineering at the Nooter Corporation that fabricates pressure vessels for the boiler, petrochemical, and nuclear industries. Robert I. Jetter has over 50 years of experience in the design and structural evaluation of nuclear components and systems for elevated temperature service. He participated in and directed design of early sodium cooled reactors and space power plants through all the US LMFBR programs. He currently consults on the development and application of elevated temperature design criteria for advanced nuclear applications.
