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.

A He-cooled divertor concept for DEMO has been pursued at Forschungszentrum Karlsruhe within the framework of the EU power plant conceptual study. The design goal is to achieve a DEMO-relevant heat flux of at least 10 MW/m2. The HEMJ (He-cooled modular divertor with multiple-jet cooling) was chosen as the reference concept. It employs small tiles made of tungsten, which are brazed to a thimble made of tungsten alloy W-1%La2O3. The W finger units are connected to the main structure of ODS Eurofer steel by means of a transition piece. The divertor modules are cooled by helium jets (10 MPa, 600°C) impinging onto the heated surface of the thimble. In cooperation with the Efremov Institute a combined helium loop & electron beam facility (60 kW, 27 keV) was built in St. Petersburg, Russia, for experimental verification of the design. Technological studies were performed on manufacturing of the W finger mock-ups. The results of high heat flux (HHF) tests till now confirm the divertor performance required. The knowledge gained from these experiments and some aspects on the design improvement are discussed in this contribution.
