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 variety in the design of laser targets experimented at CEA requires versatile and adaptable target assembly stations. Even if assembly technician know-how remains essential and indispensable, automation appears to be a valuable solution to improve productivity and target quality [Carlson et al., Fusion Sci. Technol. Vol. 70, p. 274 (2016); Lee et al., Fusion Sci. Technol., Vol. 59, p. 227 (2011); and Schmidt, Fusion Sci. Technol., Vol. 55, p. 290 (2009)]. Given the variety of target designs, automation is investigated essentially as an operator support on some specific and repetitive tasks. The gluing of the laser entrance hole membrane on gas targets is a typical example. CEA has developed an automated station dedicated to this specific operation. The main objectives are to increase productivity and reduce sensibility to operator know-how. A concept prototype (for a single holhraum) has been designed and successfully tested and the implementation of multiple devices on the station is about to begin. This paper gives a complete presentation of the station and of the developments achieved.
