![]() ![]() The only difference on the operating pressure side is that the PWR operates at about 16 Mpa. ![]() Since that time the number has increased steadily to 200 by 1981 and 225 by the end of 1983.

Major references are given for the reader in order to acquire detailed information about relevant areas. As part of the design requirements, this paper dilates upon fabrication, inspection and quality control procedures. The appendices to this paper support the main analysis. A full description of the computer program SWEL and the results is given in this paper. Safety factors for various zones of this vessel have been plotted so as to clearly indicate the vulnerable areas. Results obtained from the analysis have been fully corroborated with those available from published data. ![]() The analysis and the specially developed computer program SWEL have been applied to the proposed steel vessel for SIZEWELL 'B'. Service loads, overloads and dynamic load conditions are included. A three-dimensional elasto-plastic-fracture finite element analysis has been developed. (Receired ) Abstract-This paper attempts to present analysis and design of steel pressure vessels for Pressurised Water Reactors (PWR).
