A two phase PVRC project is generating guidelines for evaluation of pressure vessel components in accordance with the elastic stress categories of the ASME B and PV Code design by analysis methods in Section III NB and Section VIII Div. 2. The focus is on correlating three-dimensional finite element result to the stress categories. The First phase addressed the global issues; providing six recommendations which identify four areas to be studied in Phase 2. This current paper summarizes work-in-progress within PVRC, the findings and conclusions are currently under review within PVRC. The second phase of the PVRC project includes ten example problems. Seven of these have been analyzed by finite element and the results assessed; the remaining three are in progress. This paper summarizes the geometries, scope, and findings for three of the example problems. The first is a cylinder-to-cylinder juncture; the second is a small nozzle at an angle to the shell; the third is a radial nozzle. Emphasis is on establishing locations for the SCLs, including checking the validity of the SCLs.
