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.

A primarily analytical thermal analysis model is presented which allows for calculation of temperatures in fusion reactor first walls. The model utilizes input from plasma physics calculations coupling a 2-1/2 dimensional geometric analysis with a 1-dimensional heat conduction treatment to determine temperature profiles over the surface of and within the first wall. The results are primarily applicable to the steady-state operation of magnetic confinement devices such as tokamaks. Effects of wall geometry, toroidal curvature, and wall corrugation are considered in computing local power loadings from bremsstrahlung, cyclotron radiation, charged particles, and neutrons. Temperature solutions based on these loadings are developed by expanding into a MacLaurin series and utilizing the principle of superposition. A sequential calculation scheme is employed in lieu of traditional matrix methods in determining temperature distributions in composite walls. The model and corresponding solution methods are applied to three illustrative fusion reactor designs. Significant gains in accuracy are indicated over thermal analysis methods previously used.
