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.

A review of workforce trends in the nuclear community
The nuclear community is undergoing a moment of unprecedented interest and growth not seen in decades. The passage of the bipartisan Infrastructure Investment and Jobs Act and the Inflation Reduction Act are providing a multitude of new funding opportunities for the nuclear community, and not just the current fleet. A mix of technologies and reactor types are being evaluated and deployed, with Vogtle Units 3 and 4 coming on line later this year, the Advanced Reactor Demonstration Projects of X-energy and TerraPower, and NuScale’s work with Utah Associated Municipal Power Systems to build a first-of-a-kind small modular reactor, making this is an exciting time to join the nuclear workforce.

The helium cooled ceramic reflector (HCCR) test blanket module (TBM) has been designed to be installed in ITER and to verify the tritium production and the heat extraction in Korea. Lithium, beryllium, and graphite are used as a breeder, a neutron multiplier, and a reflector, respectively, which called as breeding zone (BZ) including cooling plate. The BZ was operated with the highest temperature in the TBM due to the nucler heating not only in breeding material but also structure. The margin to the allowable temperature for the breeder is very small in the current conceptual design of HCCR TBM. In the present study, feasible methods were investigated to lower the maximum temperature of the BZ. The thermal resistance and the effect of each factor were studied with a conventional CFD code, ANSYS-CFX v14.5. It is found that the thermal resistance related to the pebble beds layer was main factor to determine the breeder temperature, and the installation of the cooling fins could reduce the heat transfer resistance and lower the maximum temperature of breeder about 80°C.
