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.

Experiments were performed to determine the likelihood of a vapor explosion when injecting an inert gas (nitrogen) and a coolant (water) into a pool of molten metal (tin) in a large-scale chamber (~20 kg fuel). The injection flow rates of the water and nitrogen gas were the principal experimental variables, with average water flow rates up to 0.05 × 10-3 m3/s and gas flow rates ranging from 0.33 × 10-3 to 1.67 × 10-3 m3/s. Of 35 successful experiments, 11 resulted in an explosive interaction, as determined by audible signals, videotape, and accelerometer data. The main objective of the investigation was to determine the existence of a boundary between explosive and nonexplosive regions in the water-gas flow rate plane: Such a boundary was indeed identified and approximated by a straight line. Two experiments in which explosive interactions were obtained in the low water/gas flow regions after a relatively long time of coolant injection (~5 to 10 s) demonstrate the hitherto undervalued importance of the temporal variable.
