General Matter to build Kentucky enrichment plant under DOE lease
The Department of Energy’s Office of Environmental Management announced it has signed a lease with General Matter for the reuse of a 100-acre parcel of federal land at the former Paducah Gaseous Diffusion Plant in Kentucky for a new private-sector domestic uranium enrichment facility.

The effectiveness of an adaptive acceleration method is studied for the inner iterations in some neutron diffusion codes. The acceleration method can be easily incorporated in the process of the general first-order stationary linear iterations. The effectiveness is shown theoretically in the case when the iteration matrix is nonnegative definite. The numerical results of its applications to the successive over-relaxation and alternating direction implicit iterations are presented. It is shown to work effectively even when the fixed parameter of the iteration is not chosen optimally. Some variants of the acceleration method are also given.
