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.

Two types of heterogeneous blanket systems were tested to estimate a design margin for neutronic calculations. One system simulates a multi-layered beryllium/lithium-oxide blanket, and the other does water coolant channels in a Li2O blanket. For both systems the tritium production rate (TPR), reaction rate and neutron spectrum were measured. Those measurements were performed by NE213 and Li-glass scintillators, Li-foil and Li2O zonal block scheme for TPR, activation foils for reaction rate and proton recoil proportional counters for spectrum. In addition, gamma-ray heating was measured by spectrum weighting function technique using NE213 scintillator. Precise distribution measurements near the material boundary were performed especially by directly stacking the irradiation samples in the test blanket region to minimize a perturbation for the measurement.
