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.

Two types of heterogeneous blanket systems were tested to estimate a design margin for neutronic calculations. One system simulates a multi-layered beryllium/lithium-oxide blanket, and the other does water coolant channels in a Li2O blanket. For both systems the tritium production rate (TPR), reaction rate and neutron spectrum were measured. Those measurements were performed by NE213 and Li-glass scintillators, Li-foil and Li2O zonal block scheme for TPR, activation foils for reaction rate and proton recoil proportional counters for spectrum. In addition, gamma-ray heating was measured by spectrum weighting function technique using NE213 scintillator. Precise distribution measurements near the material boundary were performed especially by directly stacking the irradiation samples in the test blanket region to minimize a perturbation for the measurement.
