Division Spotlight
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

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.

The tritium burnup fraction fburnup can strongly affect the design of a fusion reactor since it influences the size of the tritium reprocessing plant, the on-site tritium inventory, and hence, the licensing requirements and cost of the entire plant. In this paper a simple analytic expression for fburnup is derived and then applied to typical parameters proposed for three possible fusion devices: ARIES-AT, FDF, and ITER. We find that for these parameters the burnup fraction is most strongly affected by the global recycling coefficient (through the global replacement time) and the fueling efficiency. The latter term may be the most easily influenced by plant design, such as by high-field-side pellet injection, for example. Because of the hotter edge plasmas in these devices compared to present-day tokamaks, the recycling coefficient will be lower, reducing the tritium burnup fraction. While this may not adversely affect ITER, which is limited to 400-s pulses for the inductive scenario, the tritium reprocessing for nearly continuous operation of devices such as ARIES-AT must be carefully considered in the overall plant design.
