RIC panel discusses pathway to fusion commercialization
Fusion leaders at the Nuclear Regulatory Commission’s annual Regulatory Information Conference discussed the path forward for regulating the burgeoning fusion industry. The speakers discussed government and private industry initiatives in the United States and United Kingdom, with a focus on efforts shaping the near-term deployment of commercial fusion machines.
A recurring theme was the need to explain the difference between fission and fusion. Representatives from the Department of Energy and Type One Energy highlighted this as an important distinction for regulators, as it will allow fusion to undergo its own independent maturation process for developing standards and regulations in the same way that fission has. Lea Perlas, Fusion Program director at the Virginia Department of Health, said that confusion between fission and fusion has been a common cause for misplaced concerns among community members surrounding Commonwealth Fusion Systems’ proposed fusion plant site near Richmond, Va.

In this study, the critical heat flux (CHF) in subcooled flow of Freon-113 through short vertical tubes has been investigated. In addition, the concept of local tangential flow injection has been studied as a means of CHF enhancement. The data without tangential injection (axial flow) indicate that there is an effect of heated length in the limit of very short tubes. The CHF data obtained with tangential injection show as much as 67% enhancement in CHF over axial flow data at the same conditions. In addition, it has been shown that local tangential injection could be utilized in non-uniform heating situations.
