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.

Cross sections were measured for the first time in the 5.4- to 10.6-MeV energy range for the 90Zr(n,p)90mY, 91 Zr(n,p)9lmY, 92Zr(n,p)92Y, 90Zr(n,a)87mSr, 94Zr(n,α)91Sr, and 96Zr(n,2n)95Zr reactions. The quasi-monoenergetic neutrons were produced via the 2H(d,n)3He reaction using a deuterium gas target at a variable energy compact cyclotron. Use was made of the activation technique in combination with high-resolution gamma-ray spectroscopy. Some trends in the excitation functions are discussed.
