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.

Radioactive iodine gas is a problematic species in multiple nuclear energy–related applications. Therefore, it is highly desirable to develop an adsorbent that has a high capacity for iodine. In this investigation, the iodine adsorption capacity of high-purity magnesium oxide was investigated as a function of the calcination conditions. Differences in the magnesia substrates were characterized by scanning electron microscopy and X-ray diffraction, and the iodine adsorption capacity was determined using thermogravimetric analysis. The results indicate that the calcination temperature and time have a significant impact on the adsorption capacity, with longer times and higher temperatures having a negative impact. However, under the optimal calcination conditions identified in this study (550°C for 20 min), the high-purity magnesia was found to have an adsorption capacity >300 mg of iodine per gram of sorbent. This suggests that magnesia holds promise for nuclear applications where iodine gas adsorption would be beneficial.
