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.

Cameron Tracy(CISAC), Stanford University
Cameron Tracy will introduce the Environmental Chemistry sessions with a discussion of "The Sociotechnical Challenges of the Geologic Disposition of Weapons Plutonium." Permanent disposal of weapons plutonium in a geologic repository could reduce global nuclear risk, but burying plutonium—and ensuring that it stays buried—is a major technical and political challenge. This talk will outline obstacles to disposal, progress to date, and potential paths forward.
