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.

A simple expression is given for the isothermal reversible work of formation of a vapor lens at a liquid-liquid interface, and necessary conditions derived in terms of the spreading coefficients of the two liquids on each other. The magnitude of the interfacial tension is found to be crucial to the satisfaction of these conditions, and an approximate expression of Fowkes enables an estimate of a criterion in terms of the contributions of the London dispersion forces to the interfacial tensions. A two-step mechanism for the UO2-Na system is also postulated.
