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 system of neutron-lean tandem mirror satellite reactors using the deuterium-3He (D-3He) fuel cycle has been assessed. The 3He fuel is produced via a breeder reactor, also based on the tandem mirror reactor (TMR) concept. The TMR concept was selected because, for the satellite reactors, the fusion energy is mostly in charged-particle form, so efficient, direct energy conversion can be used. For the breeder, the TMR gives a higher maximum achievable support ratio than other concepts give. The optimum satellite operating temperature was found to be ∼75 keV. The safety and cost of the satellite/breeder system were assessed. The D-3He fuel cycle becomes particularly attractive if the deuterium-deuterium (D-D) reaction can be suppressed by nuclear spin polarization. For perfect D-D reaction suppression, this would allow immediate hands-on maintainability of reactor components and allow for reduction in the magnet dimensions, since the shield would no longer be required. For no D-D reaction suppression, ∼3% of the fusion power will be in neutrons. This will then require the use of ∼40-cm shielding, along with activation concerns. Hands-on maintenance f or the satellite reactor is possible even without D-D reaction suppression, if low-activation materials are used. The radioactivity level of the 3He breeder is comparable to that of a deuterium-tritium reactor. The cost of electricity for the system, including the fuel costs, is estimated f or this system.
