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.

NC State celebrates 70 years of nuclear engineering education

The Department of Nuclear Engineering at North Carolina State University has spent the 2020–2021 academic year celebrating the 70th anniversary of its becoming the first U.S. university to establish a nuclear engineering curriculum. It started in 1950, when Clifford Beck, then of Oak Ridge, Tenn., obtained support from NC State’s dean of engineering, Harold Lampe, to build the nation’s first university nuclear reactor and, in conjunction, establish an educational curriculum dedicated to nuclear engineering.
The department, host to the 2021 ANS Virtual Student Conference, scheduled for April 8–10, now features 23 tenure/tenure-track faculty and three research faculty members. “What a journey for the first nuclear engineering curriculum in the nation,” said Kostadin Ivanov, professor and department head.

The occurrence of a steam explosion for advanced light water reactors (LWRs), whether within or below the reactor pressure vessel in the cavity, is analyzed to determine the possible hazard to structures as a result of dynamic explosion pressures. In current LWRs, in-vessel steam explosions have been determined not to pose a risk-significant threat, while ex-vessel explosions are considered in safety analyses. In advanced LWRs, such analyses are important to demonstrate that such structures will maintain their integrity so that core debris coolability is possible. This paper presents an approach to calculate the dynamic pressures from a steam explosion using the TEXAS-V model and evaluate its effects on surrounding structures using ANSYS. Scenarios for advanced LWRs are reviewed, and a severe accident scenario is used as an example to present our methodology. Such evaluation methods should be considered in future safety studies and be verified with direct comparison to data for energetic fuel-coolant interaction, such as those provided from past KROTOS tests or with current experiments in the international SERENA project.
