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.

Cross sections of the 58Ni(n,p)58Co, 51Co(n,p)59Fe, 51V(n,α)48Sc, and 59Co(n,2n)58Co reactions and isomer ratios for the 58Ni(n,p)58Co reaction were measured for some neutron energies between 9 and 14 MeV. Neutron spectrometry, with an NE-213 scintillation detector, of the beams from the D(d,n)3He reaction was used to evaluate the activation induced by breakup neutrons on natural nickel, cobalt, vanadium, and aluminum-monitor targets. The results are compared with earlier measurements and with theoretical calculations performed with the aid of the GNASH code (Hauser-Feschbach model including pre-equilibrium corrections).
