NRC to add new items to categorical exclusions list
The Nuclear Regulatory Commission has identified five categories of action to add to its list of categorical exclusions to reduce its documentation work under National Environmental Policy Act (NEPA) procedures.
These revisions are included in the final rule, “Categorical exclusions from environmental review,” which was published in the Federal Register on March 30. The final rule will become effective on April 29.

The second in a series of experiments using the High Temperature Lattice Test Reactor has been completed and provides information on the temperature dependence of k∞ for a 233UO2-232ThO2-C fuel mixture. The infinite medium multiplication factor was found to decrease by 0.0350 ± 0.0015 from 20 to 1000°C. This result provides direct information necessary in the design of the control system and in the safety analysis for advanced high temperature gas cooled reactors.
