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 study was conducted on the cross flow and mixing between water flowing in two semiopen channels. Measurements were made of the quantity of heat transferred between the hot and cold channels in a square array of parallel rods to determine the correlation between the ratio of the overall effective diffusivity for heat e to the kinematic viscosity v and the flow Reynolds number Re. The result e/v = 0.0061 Re0.98 is in general agreement with previous results, but contains numerical coefficients not previously obtained for the present geometry.
