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.

Nuclear fusion between deuterons under ambient conditions has been observed in the metal cathode of an electrolysis cell with an electrolyte of heavy water. The evidence for the fusion reaction is derived primarily from the detection of a low level of 2.45-MeV neutrons presumably from the neutron branch of the deuterium fusion reaction. However, the estimated fusion energy yield associated with the neutron output is insufficient to account for the majority of the reported energy gain if the neutron-proton branch of the deuterium fusion reaction remains about equal to ambient conditions. The excess energy gain may arise from an unobserved chemical reaction or an unfamiliar nuclear reaction. Reported evidence of an excess of 4He in the vicinity of the cathode may indicate that a 4He branch from the deuterium fusion reaction may proceed at ambient conditions through internal electron conversion without a large release of gamma rays. These issues are explored, and attempts are made to provide physical mechanisms and explanations for the cold fusion experimental observations.
