DOE fast tracks test reactor projects: What to know
The Department of Energy today named 10 companies that want to get a test reactor critical within the next year using the DOE’s offer to authorize test reactors outside of national laboratories. As first outlined in one of the four executive orders on nuclear energy released by President Trump on May 23 and in the request for applications for the Reactor Pilot Program released June 18, the companies must use their own money and sites—and DOE authorization—to get reactors operating. What they won’t need is a Nuclear Regulatory Commission license.

A conceptual study is presented for a substantial upgrade of the Frascati Tokamak Upgrade (FTU) up to B = 8 T, I = 6 MA, and R [approximately equal to] 1.3 m to study burning plasma (BP) issues in deuterium plasmas operating up to an equivalent DT gain close to Q = 2 in the ELMy H-mode and to Q = 5 with an internal transport barrier (ITB). The effect of alpha particles is simulated by ~1 MeV fast 3He minority heating produced by ion cyclotron resonance heating (20 MW). Thanks to the high-density values ([approximately equal to]4 × 1020 m-3), the FT3 plasmas are characterized by short electron-ion equipartition time (60 ms in the ELMy H-mode scenario) and slowing-down time (44 ms), with respect to the energy confinement time of ~340 ms, a feature characteristic of BP experiments but not always satisfied with present tokamak devices. Advanced scenarios at 5 T with fully noninductive current drive can be investigated with a steady-state current density profile achieved in <5 s. The aim of FT3 is to prepare ITER operation and to provide a test bed for the development of the ITER auxiliary system and diagnostics. Elements of the scientific program are as follows: the investigation of energetic particle collective effects, optimization of H-mode scenarios, development of improved H-mode scenarios and scenarios with ITBs, magnetohydrodynamic and transport studies in ITER-relevant conditions, and study of edge plasma dynamics. FT3 can use all the existing facilities available in Frascati and could be constructed in ~5 yr.
