Norway’s Halden reactor takes first step toward decommissioning
The government of Norway has granted the transfer of the Halden research reactor from the Institute for Energy Technology (IFE) to the state agency Norwegian Nuclear Decommissioning (NND). The 25-MWt Halden boiling water reactor operated from 1958 to 2018 and was used in the research of nuclear fuel, reactor internals, plant procedures and monitoring, and human factors.
NUCLEAR AND EMERGING TECHNOLOGIES FOR SPACE (NETS-2024) PLENARY SPEAKER
Randy Bell is a senior project leader at The Aerospace Corporation working in space nuclear power and propulsion. Prior to Aerospace, he served in DOE and NNSA in nuclear engineering and nuclear nonproliferation from 1991 through 2020, during this time he led research programs developing technical methods to detect and characterize weapons proliferation. Mr. Bell was the manager of Space and Remote Sensing Systems where he oversaw several small satellite programs and many advanced airborne remote sensing efforts. He headed NNSA’s Office of Nuclear Detonation Detection where he was responsible for production of operational satellite payloads as well as seismic and atmospheric detonation detection technology. Subsequently he was the Director of the Comprehensive Nuclear Test Ban Treaty’s International Data Centre where he led operation of the multinational nuclear test detection system and coordinated nuclear test monitoring activities among all Treaty member countries. Before DOE, Mr Bell was a US Navy Fast Attack Submarine Officer and continued in the reserves in numerous assignments related to national space systems. He has master’s degrees in physics from George Mason University, and computer science from Johns Hopkins University, and a B.S. in mathematics from the University of Rochester.
