Nuclear Installations Safety
Devoted specifically to the safety of nuclear installations and the health and safety of the public, this division seeks a better understanding of the role of safety in the design, construction and operation of nuclear installation facilities. The division also promotes engineering and scientific technology advancement associated with the safety of such facilities.

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 Z-IFE (inertial fusion energy) plant is a unique, inertial confined, fusion energy concept in which high yield targets will be ignited to fusion, yielding brief energy bursts in the 3 to 20-gigajoule range. The fusion reaction yields an energetic burst that consists principally of neutrons, X rays, and charged particles. The X rays rapidly attenuate in matter, causing the material to expand rapidly, thus generating a strong shock wave. This shock wave must be mitigated if the Z-IFE chamber is to last for a period of 30 to 50 years.ALEGRA simulations were conducted for a hypothetical Z-IFE chamber filled with argon gas and ionized by an X ray source. The calculations employed a set of sophisticated models, including Saha ionization, XSN and CDF opacities, bremsstrahlung radiation, linearized diffusion of X ray photons for a blackbody, fully-coupled magnetohydrodynamic models, electron thermal conduction, Spitzer thermal conductivity with cold material interpolation, and Mie-Gruneisen EOS.In order to obtain confidence in the results, a laser experiment from UCSD was simulated. In the experiment, laser photons were used to ionize argon gas. The simulations showed that ALEGRA quite successfully calculated the measured temperature, level of ionization, and spatial evolution of the argon plasma.
