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.

Idealized equilibrium expansion calculations were made to determine the characteristics of UO2 vapor bubbles produced under sodium in the capacitor discharge vaporization experiments at the Oak Ridge National Laboratory. These characteristics are the quality of the vaporized UO2, it vapor density, and the bubble diameter. A parametric study was made over the range of initial and final states expected to occur in the experiments to determine the effects of losing arbitrary amounts of energy and of vaporizing arbitrary amounts of sodium. The results are sufficiently general to be of use in estimating bubble characteristics for a hypothetical core disruptive accident in a liquid metal-cooled fast breeder reactor.
