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 reliability of selected DIII-D vacuum components has been studied to give indications of how well the vacuum confinement would perform if a liquid wall experiment were operated on a device such as the National Spherical Torus Experiment (NSTX). Data from the DIII-D vessel and vacuum system are generally applicable to the NSTX because their designs are similar. The DIII-D has accumulated operating experience data over 15 years of operations, and DIII-D-specific reliability values are comparable to previous reliability estimates for vacuum components.
