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.

The one-speed neutron transport equation with anisotropic scattering is investigated by the method of partial-range Legendre-polynomial analysis. It is found that appropriate conditions on the spatial moments can be specified by suitable integral operations of the partial-range polynomials. A numerical test suggests that such an analysis does possess potential merit for calculating some neutron transport parameters to a high degree of accuracy even in a low order approximation.
