GLE gets incentives, draft EIS
The governments of Kentucky and McCracken County have granted preliminary approval to Global Laser Enrichment for a comprehensive incentive package to support the development of the North Carolina–based company’s planned Paducah Laser Enrichment Facility in the western part of the state. The performance-based incentive package would provide as much as $98.9 million in tax incentives and other economic incentives—provided that GLE reaches the required thresholds in investments and job creation.
In addition, the Nuclear Regulatory Commission, in cooperation with the U.S. Army Corps of Engineers, has completed a draft environmental impact statement (EIS) in response to GLE’s application to construct and operate the PLEF. Members of the public can submit comments on the draft EIS by May 11 for consideration by the NRC.

We present a nonlinear acceleration algorithm for a transport criticality problem. The algorithm combines the well-known nonlinear diffusion acceleration (NDA) algorithm with a recently developed, Newton-based nonlinear criticality acceleration (NCA) algorithm. The algorithm first employs NDA to reduce the system to scalar flux, then NCA is applied to the resulting drift-diffusion system. We apply a nonlinear elimination technique to eliminate the eigenvalue constraint equation from the Jacobian matrix. Numerical results show that the algorithm can reduce the CPU time by a factor of 30 to 400 compared to traditional power iterations (PIs) combined with standard source iterations and by a factor of 3 to 5 compared to application of NDA combined with inner PIs.
