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.

INL’s new innovation incubator could link start-ups with an industry sponsor
Idaho National Laboratory is looking for a sponsor to invest $5 million–$10 million in a privately funded innovation incubator to support seed-stage start-ups working in nuclear energy, integrated energy systems, cybersecurity, or advanced materials. For their investment, the sponsor gets access to what INL calls “a turnkey source of cutting-edge American innovation.” Not only are technologies supported by the program “substantially de-risked” by going through technical review and development at a national laboratory, but the arrangement “adds credibility, goodwill, and visibility to the private sector sponsor’s investments,” according to INL.

Induced radioactivity characteristics of vanadium alloys irradiated with 14 MeV neutrons were investigated. Short and long 14 MeV irradiation modes were employed to distinguish the characteristic of radioisotopes according to their half-lives. Radioactivities in several different V-alloy samples were measured by the γ-ray spectrometry. Along with the radionuclides induced in the major constituents, those from impurities were simultaneously identified by the activation analysis. The decay profiles of the induced radioisotopes were compared with the calculation using the comprehensive activation cross section libraries of FENDL/A-2,.0 and JENDL-ACT96. From the ratios of calculation and experiment (C/E), it was proved that the FENDL/A-2.0 and JENDL-ACT96 are adequate to predict the dominant radionuclide in V, Ti, and Cr. However, there was significant underestimation for activation products of impurities of Si, Fe, Ni, Nb and possibly Mo. In particular, the amounts of Nb impurity, which ranges from 70 to 100 ppm, is almost the same as that of the chemical analysis.
