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.

VERA—Virtual Environment for Reactor Applications—is a state-of-the-art Pressurized Water Reactor (PWR) core simulator using novel computational methods that integrate reactor physics, thermal hydraulics, and fuel performance into a single simulation platform. The goal of this workshop is to learn how to run the VERA core simulator for PWR analysis. The workshop will provide basic modeling demonstrations and exercises for pin, assembly, and full-core modeling.
The training will be conducted using computational resources at the Nuclear Computational Resource Center (NCRC) at Idaho National Laboratory (INL). Before the workshop, attendees are required to have an INL NRC account (https://inl.gov/ncrc/) and a license for VERA 4.3. Single-user licenses are available through the Radiation Safety Information Computational Center (RSICC) at Oak Ridge National Laboratory (ORNL). Workshop attendees may also have a valid license through an active government use agreement or commercial license agreement for VERA through ORNL.
