NRC provides timeline update on rules, meeting EO deadline
Last May, President Trump issued Executive Order (EO) 14300, “Ordering the Reform of the Nuclear Regulatory Commission,” which mandated that the NRC review and overhaul its rules within 18 months of the EO being issued.
At a public meeting on Thursday, NRC officials shared details and an overview of the rulemaking process, saying that they were on target to have these rules ready by the November 23 deadline.

A new nonlinear coarse-mesh rebalance (CMR) method is developed and tested to accelerate the one- and two-dimensional discrete ordinates neutron transport calculations. The method is based on rebalance factors that are angular dependent and defined on the coarse-mesh boundaries only. Unlike the conventional CMR method that is only conditionally stable, Fourier analysis and numerical tests show that this coarse-mesh angular dependent rebalance (CMADR) method is unconditionally stable for any optical thickness, scattering ratio, and coarseness and that the acceleration is very effective in most cases.
