NRC proposes changes to its rules on nuclear materials
In response to Executive Order 14300, “Ordering the Reform of the Nuclear Regulatory Commission,” the NRC is proposing sweeping changes to its rules governing the use of nuclear materials that are widely used in industry, medicine, and research. The changes would amend NRC regulations for the licensing of nuclear byproduct material, some source material, and some special nuclear material.
As published in the May 18 Federal Register, the NRC is seeking public comment on this proposed rule and draft interim guidance until July 2.

The second Egyptian Research Reactor, ET-RR-2, went critical on November 27, 1997. The National Center of Nuclear Safety and Radiation Control has the responsibility for the evaluation and the assessment of the safety of this reactor. The purpose of this paper is to present an approach to the optimization of the fuel element plate, in which every target is considered as a separate objective to be optimized. Multiobjective optimization is a powerful tool for resolving conflicting objectives in engineering design and numerous other fields. The fuel element plate is designed with a view to improve reliability and lifetime, and it is one of the most important elements during the shutdown. In this paper, we present a conceptual design approach for the fuel element plate, in conjunction with a genetic algorithm to obtain a fuel plate that maximizes a fitness value for optimizing the safety design of the fuel plate.
