Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

Nuclear energy tax credits remain—for now—in latest federal budget
The U.S. House of Representatives pulled an all-nighter this week to narrowly pass (by a vote of 215–214) a revised budget plan Thursday morning and send it to the Senate for a reconciliation vote of its own.
Nuclear advocates have been monitoring the latest language regarding tax credits that have been in place since 2021 to help drive deployment. Earlier versions of the bill called for phasing out the nuclear credits.
