ASME STP-NU-037

ASME STP-NU-037 – Operating Condition Allowable Stress Values in ASME Section III Subsection NH

The current operating condition allowable stresses provided in ASME Section III, Subsection NHwere reviewed for consistency with the criteria used to establish the stress allowables and with theallowable stresses provided in ASME Section II, Part D. It was found that the So values in ASME IIINHwere consistent with the S values in ASME II-D for the five materials of interest. However, itwas found that 0.80Sr was less than So for some temperatures for four of the materials. Only valuesfor alloy 800H appeared to be consistent with the criteria on which So values are established. Withthe intent of undertaking a more detailed evaluation of issues related to the allowable stresses inASME III-NH, the availabilities of databases for the five materials were reviewed and augmenteddatabases were assembled.
