Ariz. governor vetoes “fast track” bill for nuclear
Gov. Katie Hobbs put the brakes on legislation that would have eliminated some of Arizona’s regulations and oversight of small modular reactors, technology that is largely under consideration by data centers and heavy industrial power users.

Time-of-flight measurements of the fast-neutron angular flux spectrum in CH2 and LiH spheres have been made to test shielding calculations. The spheres were excited with an isotropic photofission neutron source. Measurements were compared with discrete ordinates and Monte Carlo calculations. The major calculational difficulty was found to be the representation of the zero-degree flux in the discrete ordinates program.
