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.

Fusion reactors will require specially engineered structural materials that will simultaneously satisfy the harsh conditions, such as high thermomechanical stresses, high heat loads, and severe radiation damage, without compromising on safety considerations. The simulation of 14.7-MeV protons and 3.6-MeV α-particles irradiation processing using different fusion structural materials, such as graphite, titanium, zirconium, molybdenum, tantalum, and tungsten, was studied. The open-source three-dimensional computer simulation code SRIM (2013 version) was used to determine the protons and α-particles penetrability into the target material as well as the range dependence of the protons and α-particles energies. The protons and α-particles distribution range and their trajectories in the target materials were determined. The effect of the target materials’ atomic mass on the 14.7-MeV protons and 3.6-MeV α-particles penetration range was determined. Also, the phonons and ionization of the target materials induced by these irradiated particles were studied.
