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.

Charpy impact specimens, one third the size of standard specimens in all dimensions have been tested for a variety of steels and the data have been compared to standard specimen data. The absorbed energy curves are qualitatively similar for both specimen types, and quantitative evaluations of dynamic yield strength and cleavage fracture stress are similar as well. However, differences in constraint between standard and subsized specimens must be accounted for, and these differences are influenced by the flow behavior of the test material.
