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.

A technique has been developed for detecting defective SiC layers in silicon carbide-pyrolytic carbon coated fuel particles. The outer coating of carbon is burned off at 800°C, and the particles are pressurized at 1000 lb /in.2 in a mercury porosimeter. Mercury is forced through any defects in the SiC layer and into the porous carbon. The particles are examined by a low-voltage microradiographic technique. Defective particles were detected in some batches of coated fuel particles.
