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.

El Salvador: Looking to nuclear
In 2022, El Salvador’s leadership decided to expand its modest, mostly hydro- and geothermal-based electricity system, which is supported by expensive imported natural gas and diesel generation. They chose to use advanced nuclear reactors, preferably fueled by thorium-based fuels, to power their civilian efforts. The choice of thorium was made to inform the world that the reactor program was for civilian purposes only, and so they chose a fuel that was plentiful, easy to source and work with, and not a proliferation risk.

To effectively reduce the probability of instrumentation and control (I&C) equipment aging failures in nuclear power plants, a preventive replacement aging treatment strategy should be adopted. A single failure–oriented and component aging sensitivity classification model is put forward to classify I&C equipment aging in nuclear power plants, and three methods for assessing I&C equipment life cycles (i.e., aging tests, standards and specifications, and failure data) are provided. Meanwhile, provided with the characteristic curves of I&C equipment aging failures in nuclear power plants, specific aging treatment steps are put forward, including (1) defining the scope of aging treatment in horizontal and longitudinal dimensions of signal flow direction and equipment composition; (2) determining the aging treatment implementation cycle by a life cycle margin setting method; (3) refining the aging treatment implementation process by division of four stages, namely, aged equipment classification, aging data management, aging treatment implementation, and aging testing feedback, to ensure reliable and safe operation of I&C equipment in nuclear power plants.
