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.”

A procedure exploiting time-dependent generalized perturbation theory applied to the nuclide field is proposed for cases of interest, namely for fuel burnup and buildup problems during the reactor life cycle and for sensitivity analyses of actinide production estimates. The numerical results so far obtained are indicative of the reliability of the proposed method.
