NRC v. Texas: Supreme Court weighs challenge to NRC authority in spent fuel storage case
The State of Texas has not one but two ongoing federal court challenges to the Nuclear Regulatory Commission that could, if successful, turn decades of NRC regulations, precedent, and case law on its head.

Studies have been performed to evaluate the isotopic neutron source 252Cf for neutron radioraphy. By special methods of fine tuning it is possible to obtain neutron radiographs that can be compared with those obtained from a nuclear reactor facility using very low collimation (gadolinium foil converter, medium resolution film, 1:25 collimator ratio). The 252Cf exposure necessary for this quality neutron radiograph is 1 mg for 100 h (or 10 mg for 10 h, etc.). A neutron source, 244Cm-Be, expected to become available as a by-product of the nuclear power program, provides neutron radiographs similar in quality to those from 252Cf.
