Throughout the year the Welding Research Council publishes bulletins which are final reports from projects sponsored by the council, important papers presented before engineering societies, and other reports of current interest which are not published in Welding Research. A large number of the published bulletins are pertinent for vessel designers.

The counsel and assistance of the members of the Pressure Vessel Research Committee of the Welding Research Council and the work of N. Murayama of the Nippon Steel Company, who performed much of the research as part of his graduate program at Lehigh University, is gratefully acknowledged. 

A. The material used to manufacture the flywheel of the reactor coolant pump motor will be produced by a commercially acceptable process that minimizes flaws, such as the vacuum melt and degassing process. This provides adequate fracture toughness properties under reactor operating conditions. The acceptance criteria for flywheel design will be compatible with the safety philosophy of the Pressure Vessel Research Committee (PVRC) of the Welding Research Council (WRC) primary coolant pressure boundary criteria as appropriate considering the inherent design and functional requirement differences between the pressure boundary and the flywheel. 

Since the compressive loads in Section II, Part D do not account for time dependent loads, the Welding Research Council (WRC) published Bulletin 443 for calculating design limits for elevated temperature buckling based on theory as well as factors from Section III, Division 1- Subsection NH. Bulletin 443 presents equations for cylinders under axial compression as well as external pressure, and spheres under external pressure.
