Who’s in the running for DOE Nuclear Lifecycle Innovation Campuses?
Today is the Department of Energy’s deadline for states to respond to a request for information on proposed Nuclear Lifecycle Innovation Campuses. Issued on January 28, the RFI marks the first step toward potentially establishing voluntary federal-state partnerships designed to build a coherent, end-to-end nuclear fuel cycle strategy for the country, including waste management, according to the DOE.

An exact infmite-series solution to the one-speed neutron transport equation in spherical geometry is presented. The analysis is based on a partial-range variant of the spherical harmonics formalism and admits arbitrary directional discontinuities in the vector flux. Numerical results are presented to illustrate the appearance of discontinuities in the flux associated with an absorbing sphere.
