Report: Constellation discusses TMI restart with Pa. officials
Constellation Energy is in talks with the governor’s office and state legislators about funding to restart a unit at Three Mile Island nuclear plant, Reuters has reported. The ongoing talks have been described as “beyond preliminary” by two sources.

Measurements are reported on the yield of neutrons from protons in the energy range from 7 to 17 MeV striking a stopping-length target of deuterium gas. This combination of beam and target is being investigated as an alternative to spallation for accelerator-driven transmutation technology with perhaps equivalent or lower energy cost per neutron. The concept includes neutrons produced from a cascade of reactions starting with the p + d reaction giving rise to subsequent fusion neutrons and neutrons from higher-order breakup reactions. In our application the incident proton energy is expected to be ~100 MeV so that most of the neutrons produced in these reactions will be higher-energy neutrons that can undergo multiplication in surrounding beryllium or lead. The results reported here for lower proton energies indicate that the expected fusion and higher-order breakup reactions have been observed, and they provide the basis for a measurement at 100 MeV to confirm the larger proton-induced cascade benefits expected at higher proton energies.
