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 solid solubility and diffusion of plutonium in aluminum were studied at 600°C. Cylindrical diffusion couples were prepared by coextrusion, and consisted of a core of 7 weight % plutonium-93% aluminum alloy clad with aluminum. Quantitative autoradiography was utilized to determine the solid solubility, while metallographic measurement furnished data for calculation of a diffusion coefficient.
