A full draft of a new supplement to the AISC Specification for Safety-Related Steel Structures for Nuclear Facilities (ANSI/AISC N690-12) is now available for public review. Comments are due by January 19.

Developed by an AISC Adhoc Subcommittee under Task Committee 12—Nuclear Facilities Design and ultimately approved by the AISC Committee on Specifications, the supplement incorporates a new appendix providing requirements for the design and construction of steel-plate composite walls.
