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.

TerraPower begins U.K. regulatory approval process
Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.
TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.

As part of the U.S. DOE Office of Fusion Energy Nuclear Data Needs program, we have continued assessment of the nuclear data needs for the development of fusion energy. We have identified and reviewed the high priority elements whose neutron emission data are needed for a near-term fusion ignition facility and fusion power reactor designs for demonstrating the scientific and engineering feasibilities of fusion energy. We found that most of the elements identified here are lacking experimental data from 6 to 15 MeV except hydrogen, lithium, beryllium, and copper. A list of high priority dosimetry cross sections was developed that includes some 29 reactions, including 6 reactions recommended by the plasma diagnostic group of PPPL. Of these 29 reactions, 18 cross sections were chosen to be included in the ENDF/B-VI dosimetry files. The activation cross sections needed for elements to be used in the near-term ignition device and future power reactors were compiled. These cross sections were prioritized according to their activation levels and half-lives of their activation products. All these cross sections are going to be included in the END/B-VI activation files.
