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.

We use molecular dynamics simulations to study the irradiation-induced point-defect clustering kinetics in CeO2 as a surrogate for UO2, the most widely used nuclear fuel. Remarkably, the cluster-formation mechanism involves a partial self-healing response of the perfect crystal to the radiation-induced defects, by spontaneous creation of new point defects with negative formation energy. These "structural" defects neutralize the cluster by screening its long-range Coulomb potential, thereby localizing the damage. The observation of a similar lattice response in MgO and UO2, in spite of very different types of clusters involved, suggests that this partial self-healing screening behavior may be intrinsic to all ionic crystals.
