Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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 computerized systems model of a heavy-ion fusion (HIF) reactor power plant is presented. The model can be used to analyze the behavior and projected costs of a commercial power plant using an induction linear accelerator (Linac) as a driver. Each major component of the model (targets, reactor cavity, Linac, beam transport, power flow, balance of plant, and costing) is discussed. Various target, reactor cavity, Linac, and beam transport schemes are examined and compared. The preferred operating regime for such a power plant is also examined. The results show that HIF power plants can compete with other advanced energy concepts at the 1000-MW(electric) power level [cost of electricity (COE) ∼50 mill/kW-h] provided that the cost savings predicted for Linacs using higher charge-state ions (+3) can be realized. The induction Linac driver is still a major component of the total capital cost (43%), but it no longer appears that large 4000-MW(electric), $5 billion (1984) power plants will be required to make the economics of HIF look favorable. More importantly, the results also indicate that there are several different combinations of target and reactor cavity options that lead to COEs within 10% of the overall minimum. The induction Linac's higher efficiency (>20%) is able to compensate for changes in target concept (gain) and cavity type with minimal change in COE. The potential cost reductions and apparent flexibility identified by this study together with the established performance data base from present-day accelerators are leading to renewed interest in induction Linacs for near-term target development applications.
