Here is a recap of recent industry happenings:
Supply chain contract signed for Aurora
Oklo, the California-based developer of the Aurora Powerhouse sodium-cooled fast-neutron reactor, has signed a contract with Siemens Energy that is meant to de-risk supply chain and production timeline challenges for Oklo. Under the terms, Siemens will design and deliver the power conversion system for the Powerhouse, which is to be deployed at Idaho National Laboratory.
John Graham joined ANS in 1970. He was a Fellow and served as treasurer before becoming the 41st president of the Society. He was active in the Aerospace Nuclear Science and Technology Division, as well as the Nuclear Installations Safety Division.
He was been engaged in nuclear safety for 60 years, including ongoing work with the Pacific Nuclear Council on promotion of peaceful uses of nuclear technologies, since 1997. Graham began a career with Westinghouse in 1969 as Manager of Nuclear Safety at Westinghouse Advanced Reactors Division, Madison, Wisc., with responsibility for safety of the Clinch River Breeder Reactor in Tennessee, among other projects. In 1985, he became the Licensing Manager for the Basalt Waster Isolation Project.
After he left Westinghouse, he was named the Director of Nuclear Safety for Atomic Energy of Canada Limited (AECL) until 1992, when he became vice-president of British Nuclear Fuels (BNFL). He also worked for the U.K. Atomic Energy Agency as a senior scientist and for the Atomic Energy of Canada Research for British Nuclear Fuels as a Director of Safety. He was a recognized Fellow at Westinghouse.
He earned a BS in mathematics from the University of Wales, with graduate work at the University of Illinois and the University of London.
He wrote Fast Reactor Safety in 1971 and authored 25 other books.
