ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

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 Laser Megajoule (LMJ) Cryotarget Positioner (PCC) will be used to set cryogenic targets in the vacuum chamber centre of this experimental facility for fusion by inertial confinement. In the French concept, only the targets will be transferred at cryogenic temperature to the PCC, using a Cryotarget Transfer Unit (UTCC). Some of the specifications are very ambitious. Indeed, the targets must be transferred automatically between those cryorobots, at a temperature between 20 K and 29 K. Then, they have to be cooled carefully by the PCC to the triple point (TP) of deuterium-tritium mixture at a rate of 0.5 mK/min. Just below the TP they have to be regulated with an accuracy of +/- 2 mK. Eventually, the DT mixture has to be set 1.5 K below the TP.Scale one prototypes of the cryostats have been built at the Low Temperature Laboratory (SBT) in CEA-Grenoble, France, to deal with specific issues: cryogenic contact resistances, fine cryogenic temperature regulation, test of the feasibility of various thermodynamic paths, 6 degrees of freedom robot positioner, vision control of the transfer and automation. This paper presents the results obtained with these prototypes regarding topics specific to cryogenic transfers, followed by very fine regulation of temperature around 20 K and by dynamic quenching just before the laser shot.
