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 method of forming one-dimensional networks that are equivalent to two-dimensional wave propagations with fluid-structure interactions was developed. The method was verified by analysis of the simple shaker for a computational experiment by the use of the MULTIPLEX code for one-dimensional hydraulics with fluid-structure interactions. By applying the method of network formation, the Fritz-Kiss experiment was subsequently analyzed. In the latter case, the computed in-water frequency was 17.39 Hz, in good agreement with the measured value, 17.0 Hz. Thus, the MULTIPLEX code was verified for analyses of two-dimensional systems with application of the network model.
