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 risk assessment of potential events at Susquehanna Steam Electric Station (SSES) is described wherein a loss of cooling occurs in a spent-fuel pool (SFP). This evaluation was performed as part of the evaluation of potential generic issue 93-01, regarding the safety impact of incidents involving the loss of SFP cooling (SFPC). The analysis investigates allegations and concerns identified in a Title 10, Part 21 Code of Federal Regulations (10 CFR 21) report filed by two former contract employees, who alleged that SSES has design deficiencies associated with SFPC that make it susceptible to unsafe conditions. The evaluation estimates the likelihood of a loss-of-SFPC event at SSES and the associated probability of the SFP heating up to nearboiling conditions. The evaluation also includes an assessment for such near-boiling events for their contribution to core damage and an estimate of order-of-magnitude core damage frequency. The analysis addresses SSES plant conditions that existed prior to the 10 CFR 21 report and also current plant conditions. Data for this analysis were obtained from the SSES licensee and from other relevant data sources, including probabilistic risk assessment information. Background for the evaluations performed, the methodology used in the evaluation, the data and modeling used for the analyses, the analysis techniques and results, and conclusions are presented.
