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.
Director
Princeton Plasma Physics Laboratory
Steven Cowley, a theoretical physicist and international authority on fusion energy, became the seventh Director of the Princeton Plasma Physics Laboratory (PPPL) on July 1, 2018 and Princeton professor of astrophysical sciences on September 1, 2018. Prior to that he was president of Corpus Christi College and professor of physics at the University of Oxford in the United Kingdom (2016-2018). Cowley was chief executive officer of the United Kingdom Atomic Energy Authority (UKAEA) and head of the Culham Centre for Fusion Energy from 2008-2016. He earned his doctorate at Princeton University in astrophysical sciences in 1985 and was a staff scientist at PPPL from 1987 to 1993. From 2011-2016 he was a member of the UK Prime Minister's Council on Science and Technology. He is a Fellow of the Royal Society and of the Royal Academy of Engineering, and was knighted by the Queen of England in June 2018 for his role in fusion science.
