Tennessee fusion regulations take effect
On June 9, Tennessee became the first U.S. state to implement its own regulatory framework for nuclear fusion machines. It’s a notable step in the rapidly developing field of fusion regulation, and will help Tennessee prepare to regulate Type One Energy’s proposed commercial fusion power plant near Oak Ridge.

The following drafts are open for public comment:
ANS-2.36-202x, Accident Analysis for Aircraft Crash into Reactor and Nonreactor Nuclear Facilities [proposed new standard]
This standard’s broad reactor and nonreactor nuclear facility applicability provides the user the requirements and guidance to evaluate and assess the significance of aircraft crash risk on nuclear facility safety and provides a framework of stepwise increases in analytical sophistication aimed to demonstrate that an aircraft crash either does or does not exceed a risk level of concern equivalent to other generally applied sources of risk from the operation of nuclear facilities.
Comment deadline: June 20, 2026 (comments received after this date will not be accepted)
ANS-8.22-202x, Nuclear Criticality Safety Based on Limiting and Controlling Moderators [revision of ANSI/ANS-8.22-1997 (R2021)]
This standard provides criteria for limiting and controlling moderators in operations with fissile materials. This standard applies to those operations that depend on moderator control for maintaining subcritical conditions. This standard does not apply to concentration control of fissile materials.
Comment deadline: August 10, 2026 (comments received after this date will not be accepted)
Projects at ballot have completed drafts that have been issued for subcommittee or consensus committee ballot/concurrent public review. Before proceeding, all comments must be considered.
