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.

This 4-hour workshop explores best practices in shielding analyses with the SCALE code system, for neutron and photon particle transport, material activation, and source term generation. Participants will learn how to simulate activation of materials, generate fission sources, and use a variance reduction method (CADIS or FW-CADIS) to estimate a dose rate calculation for a microreactor. They will also learn how to utilize SCALE’s graphical user interface to design and visualize the geometry of the model, investigate simulation results, and overlay mesh tally results onto the geometry.
Agenda:
No prior SCALE experience is required for this workshop. Participants are encouraged to bring their laptops with SCALE 6.3.1 installed. SCALE 6.3.1 can be requested from RSICC (rsicc.ornl.gov/Default.aspx). Participants without a SCALE 6.3.1 license or without a laptop may still attend the demonstration. The workshop material (presentations, input and output files for the demos) will be made available to all participants. Information about SCALE can be found here: www.ornl.gov/scale
