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.

To obtain the probability distribution of the burst waiting time of neutron initiation in a multiplying assembly, a method that simulates the neutrons that induce a persistent fission chain is introduced in this paper. By this simulation method, neutron initiation experiments performed on Godiva-II and CFBR-II at a reactivity above prompt critical and performed on Godiva-I at a reactivity above delayed critical are studied. The probability density function of the burst waiting time of these experiments is calculated, and the results agree well with those of the experiments. Based on this simulation algorithm, the strength of the delayed neutron source changing with time is also calculated, which helps in the understanding of these neutron initiation experiments conducted on the pulse reactor.
