NN Asks: What did you learn from ANS’s Nuclear 101?
Mike Harkin
When ANS first announced its new Nuclear 101 certificate course, I was excited. This felt like a course tailor-made for me, a transplant into the commercial nuclear world. I enrolled for the inaugural session held in November 2024, knowing it was going to be hard (this is nuclear power, of course)—but I had been working on ramping up my knowledge base for the past year, through both my employer and at a local college.
The course was a fast-and-furious roller-coaster ride through all the key components of the nuclear power industry, in one highly challenging week. In fact, the challenges the students experienced caught even the instructors by surprise. Thankfully, the shared intellectual stretch we students all felt helped us band together to push through to the end.
We were all impressed with the quality of the instructors, who are some of the top experts in the field. We appreciated not only their knowledge base but their support whenever someone struggled to understand a concept.

Mechanical, thermal and neutronics design aspects of the toroidal field coil centerpost (CP) for a spherical torus based volumetric neutron source (ST-VNS) are presented. It is being investigated with support of a DOE-SBIR under the direction of TSI Research Inc. of Solana Beach, CA. The ST-VNS is to provide a test bed for developing nuclear technologies, as well as qualifying blanket designs for future fusion reactors. The device is scoped to be capable of staged operation with a neutron wall loading range of 0.5–4.0 MW/m2 as the physics and engineering design assumptions are raised from modest to aggressive levels. Margins in the design are ensured, since operation at 2 MW/m2 neutron wall loading will satisfy the mission of the VNS. The device has a naturally diverted plasma with a major radius of 1.1m, a minor radius of 0.78 m for an aspect ratio of 1.4, an elongation of 3, a triangularity of 0.6 and can be driven with neutral beams (NB) or radio frequency (RF). It utilizes a single turn; unshielded normal conducting CP made of dispersion strengthened (DS) Cu that is 15.5 m long and has a diameter of 0.55 m at the midplane. Resistive heating at the start of operation is 153 MW and increases to 178 MW after three full power years. The effect of transmutation in the Cu causes an increase in the resistivity, producing a shift in the CP current towards the center. The results of this shift on power distribution are reported.
