Proposed rules on ALARA, reactor licensing revamp introduced by NRC
A proposed rule from the Nuclear Regulatory Commission would update radiation protection regulations and remove “as low as reasonably achievable” (ALARA) language without changing specific radiation exposure limits that are based on the linear no-threshold (LNT) model of low-dose radiation health effects. A second proposed rule would reform reactor licensing, safety oversight, and siting practices with changes the agency said are the most significant in years.
The NRC unveiled the two proposed rules on July 1 and published them in the ADAMS public document library the same day. The rules have not, at this writing, been published in the Federal Register, but once they are, each rule will be open for public comment for 45 days.

The Mirror Advanced Reactor Study (Mars) considers two blanket designs: A high temperature helium (1000°C) and lead lithium cooled blanket for synthetic fuels production as well as a simplier lead lithium cooled blanket for electrical power production. These blankets employ fundamentally different maintenance concepts for yearly replacement. A method for replacing this synfuel blanket has been developed and time of removal estimated, Methods for blanket disassembly and preparation for off-site shipment have also been developed and are presented.
