Scalable production of nuclear battery alpha emitters using fusion neutrons

J. F. Parisi

Nuclear batteries powered by alpha decay have been deployed successfully for over 60 years, on a worldwide Pu supply of kilograms per year. We show that the 14 MeV neutrons…

Enhanced alpha channeling with spin-polarized fuel

J. F. Parisi, A. Diallo, J. W. S. Cook

The nuclear spin state of deuterium-tritium (D-T) fuel sets both the D-T fusion cross section and the emission direction of the fusion-born alphas and neutrons. We show two ways th…

Self-subsidizing Mercury Remediation with Fusion Reactors

J. F. Parisi, J. Azad

Fusion reactors can permanently remediate mercury by using it as a neutron multiplier: each (n,2n) reaction reduces the neutron number towards Hg which quickly decays int…

Isotope Production in Fusion Systems

J. F. Parisi, J. A. Schwartz, S. E. Wurzel +2

Fusion systems producing isotopes via neutron-driven transmutation can achieve economic viability well before reaching energy breakeven. Incorporating carefully selected feedstock…

Isotope Production in Muon-Catalyzed-Fusion Systems

J. F. Parisi, A. Rutkowski

Producing valuable isotopes with high-flux high-energy neutrons generated by muon-catalyzed fusion (CF) reactions could substantially improve the economic prospects for muon-ca…

Persistence of Deuterium and Tritium Nuclear Spin-Polarization in Presence of High-Frequency Plasma Waves

J. W. S. Cook, H. Ali, J. F. Parisi +2

We present first-principles numerical calculations of the depolarization rate of spin-polarized deuterium and tritium nuclei in realistic tokamak plasmas, driven by resonant intera…
