UPDATE- the technical details and proposed timeline are provided in the next nextbigfuture article
The team published its reactor design and cost-analysis findings last spring and will present results Oct. 17 at the International Atomic Energy Agency's Fusion Energy Conference in St. Petersburg, Russia.
The UW's design is known as a spheromak, meaning it generates the majority of magnetic fields by driving electrical currents into the plasma itself. This reduces the amount of required materials and actually allows researchers to shrink the overall size of the reactor.
New Energy and Fuel reports the concept entails a recently discovered imposed-dynamo current drive (IDCD) and a molten salt (FLiBe) blanket system for first wall cooling, neutron moderation and tritium breeding. The feasibility of the energy generating system is made possible from newly available materials and an ITER-developed cryogenic pumping system - See more at:
The Dynomak will have very high neutron wall loading and FLiBe blanket which offers most attractive blanket power density, which is also an economic metric for power plant considerations. Imposed-Dynamo Current Drive (IDCD) perturbs and sustains a stable spheromak equilibrium, avoiding severe confinement quality limitations apparent in previous dynamo-driven experiments. IDCD enables energy efficient current drive when compared to conventional current drive methods, further reducing the recirculating power fraction
