NRC proposed rule for licensing reactors authorized by DOE, DOD
Nuclear reactor designs approved by the Department of Energy or Department of Defense could get streamlined pathways through the Nuclear Regulatory Commission’s commercial licensing process should applicants wish to push the technology into the civilian sector.
A proposed rule introduced April 2 by the NRC would “improve NRC licensing review efficiency, where applicable, by explicitly establishing by regulation an additional means for reactor applicants to demonstrate the safety functions of their reactor designs, and thus, would contribute to the safe and secure use and deployment of civilian nuclear energy technologies.”

In a recent effort to produce fissile material in the blanket of a fusion-fission hybrid reactor.1,2 it is expected that the wave heating might enhance the fusion reaction rate by a factor of 5 in the experimental reactor and by a factor of 2 in the demonstration reactor. Therefore, Fokker Planck equation with ICRH has been solved to obtain the non-maxwellian distribution function for deuterons. It is pointed that Krapchev's paper3might lead to an overoptimistic result due to the improper reaction cross-section formula which is supposed to be applied only for low energy cases. Using the correct cross-section formula4, the calculations show that it is necessary to invoke other kind of non-maxwellian distribution function. Nonequipotential magnetic surfaces5in H-mode may cause such non-maxwellian distribution function.
