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.

Webinar: MC&A and safety in advanced reactors in focus
Towell
Russell
Prasad
The American Nuclear Society’s Nuclear Nonproliferation Policy Division recently hosted a webinar on updating material control and accounting (MC&A) and security regulations for the evolving field of advanced reactors.
Moderator Shikha Prasad (CEO, Srijan LLC) was joined by two presenters, John Russell and Lester Towell, who looked at how regulations that were historically developed for traditional light water reactors will apply to the next generation of nuclear technology and what changes need to be made.

The goals for hydrogen control in nuclear power plants are to design countermeasures that allow operators to avoid deflagration-to-detonation transition (DDT) and to ensure the survivability of equipment. These goals could be achieved by using a quenching mesh. Flame arrest tests are carried out using a quenching mesh with a 0.3-mm gap distance. When the quenching mesh is installed between compartments, the quenching mesh plays a role in flame quenching below 1.8 bars of the initial pressure and less than ~1.6 m/s of the flame velocity. Therefore, if the quenching mesh is properly installed in the containment, the flame could be arrested within the mesh boundary, resulting in the prevention of DDT and the survivability of equipment. Flame-quenching criteria are suggested using the expansion ratio, the initial air pressure, and the flame velocity.
