Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

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.

An extensive program of experimental work has been performed at the TNO Prins Maurits Laboratory on the quenching of hydrogen/air flames in various geometries on a medium scale by partial inertization. The main parameters investigated were the composition of the gas mixture and the measure of obstruction of the flow field in order to vary the degree of turbulence. The fuel concentration was varied between equivalence ratios of 0.25 and 1.00. The influence of carbon dioxide and nitrogen addition was investigated during separate trials. Both inert gases were added up to 30 vol% in the various geometrical arrangements. On the basis of an initial study by Sherman et al., a basic methodology has been developed for the estimation of explosion effects of hydrogen/air/inert mixtures. The method is a simplification of the actual processes during the experiments and is therefore only indicative. It is intended to be used by those who are not expert in the field. Knowledge of the gas composition can be used to safety advise applications on a large scale, on the basis of four conservatively chosen regimes of explosion severity.
