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.

An autoclave and a water treatment and monitoring system simulating the secondary side of a steam generator are used to investigate the hideout phenomena of sodium chloride in a tube-support-plate crevice. The primary-side heating tube is simulated by an internal heater. The experiments are performed at 1 atm pressure. The effects of heat flux, bulk concentration, crevice width, and the presence of a porous medium are investigated. It is found that the solute concentrates heavily near the upper end of the crevice. This concentration distribution in the axial direction is confirmed by a model developed in a parallel study. The hideout rate increases with increasing heat flux and bulk concentration. The concentration level in the crevice at a given time increases with increasing heat flux and bulk concentration and with decreasing crevice width. The presence of a porous medium in the crevice significantly enhances the concentration effect.
