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 prototype of an in-line vacuum-distillation sodium sampler has been successfully tested in the nonradioactive secondary sodium system at EBR-II. A 125-g sample of sodium is distilled in ∼3 h at an absolute pressure of 5µ and a temperature range of 675 to 700°F. Sample size is reproduced to better than 1%. The sampler is used to determine nonvolatile trace-metal and sodium-compound concentrations in the ppb-ppm range. Results of tests with the prototype are being used to design a model for installation in the radioactive EBR -II primary sodium system.
