There has been some recent coverage of the Dynomak nuclear fusion project in IEEE Spectrum and other sources over the last few days.
Nextbigfuture had extensive coverage of the Dynomak over 6 weeks ago. Dynomak makes the claim that they will be cheaper than coal power. The Dynomak is priced out at about $2.7 billion for a 1 gigawatt nuclear reactor. Nuclear fission reactors in China are lower than that cost and China's coal plants tend to be cheaper. China is developing a follow on to pressure water reactors which is the super-critical water reactors. The supercritical water reactor might be commercially ready around 2025 and could be about $1.5 to 2 billion for a 1 gigawatt nuclear reactor. The Canadian Terrestrial Energy molten salt reactor could have its first commercial scale unit in 2020 and could eventually be less than 1 cent per kilowatt hour.
Nextbigfuture had an updated summary of the prospects for commercial nuclear fusion. Below is a new update.
The Dynomak reactor system is the possible realization of economical fusion enabled by Imposed-Dynamo Current Drive (IDCD). IDCD could enable a spheromak commercial fusion development path.
• High CD (Current drive) efficiency improves over the tokamak.
• 30% CD efficiency enables the spheromak with high TBR and economically competitive with coal.
The HIT-SI, a cold (~10-20 eV) concept exploration experiment, has demonstrated such efficient sustainment with adequate confinement. (Reaches stability beta-limit with current drive power) IDCD.
The Steady Injective Helicity Injection method has achieved 90 kA toroidal current and current gains approaching 4.
NIMROD simulations of a bigger and hotter HIT show fluctuations may not break flux surfaces of stable equilibria
