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.

The electrolysis process is essential in the water detritiation subsystem using the combined electrolytic catalytic exchange process. A special experimental program was designed to characterize a modified HOGEN H Series industrial electrolyzer. The tritium amount transferred to hydrogen gas, the water enrichment factor, and the number of hours necessary to attain a steady-state regime were parameters of primary interest in the experiments. To minimize the necessary time for a steady-state regime, the holdup of the water electrolyzer was chosen as the minimum value allowed for safe and constant parameter operation in all experiments. The stationary regime was attained after 120 h, with an enrichment factor near 5, and an amount of 18% to 19% of tritium transferred from tritium-enriched water to hydrogen gas. These parameters were obtained in all three experiments, and the modeling software of isotope separation by electrolysis confirmed the results.
