The design of steel sections according to the requirements in the American Society of Mechanical Engineers (ASME) specifications, Rules for the Construction of Nuclear Power Plant Components, Section III – Subsection NF has been implemented and the steel design page has been updated to allow the design parameters to be defined and assigned.

Post analysis steel design code checking requirements for the required ASME NF code can be selected by entering the Design | Steel page and setting the ASME code / year in the Current Code option in the Steel Design - Whole Structure dialog:

The method for selecting design parameters and assigning them to the members to change them from the default values is exactly the same as for all other steel design codes.  Additionally, choosing members that are to be checked or selected for maximum utilization follows exactly the same method as for all other steel design codes. 

For more information on the technical requirements of this design code, including the full set of parameters and default values, see the new section in the D1.L. American Codes - Steel Design per ASME NF Codes.
