From Capitol Hill: Nuclear is back, critical for America’s energy future
The U.S. House Energy and Commerce Subcommittee on Energy convened its first hearing of the year, “American Energy Dominance: Dawn of the New Nuclear Era,” on January 7, where lawmakers and industry leaders discussed how nuclear energy can help meet surging electricity demand driven by artificial intelligence, data centers, advanced manufacturing, and national security needs.

The tokamak systems code (SuperCode) is used to identify lower-cost ITER options. Superconducting coil, lower-cost options are found by: (1) reducing the ITER technical objectives (e.g., driven burn and lower wall load), (2) using more aggressive physics (advanced physics) assumptions (e.g., higher shaping, better confinement, higher beta, etc.), and (3) more aggressive engineering assumptions (reduced shield/gaps and inductive requirements). Under ITER nominal physics assumptions, but designing for a driven Q = 10 operation results in ∼30% cost reduction if the required neutron wall load is dropped to 0.5 MW/m2. Assuming advanced physics guidelines leads to cost savings of up to 40% in an ignited device with a major radius as low as R = 5.5 m. Designing this device for Q = 10 results in additional cost savings of 10%. If reduced inboard shield and scrapeoff is assumed, and no inductive capability is required, machine size and cost benefits tend to saturate at about R = 5 m and 50% of the ITER-EDA cost.
