Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

Hinkley Point C gets over $6 billion in financing from Apollo
U.S.-based private capital group Apollo Global has committed £4.5 billion ($6.13 billion) in financing to EDF Energy, primarily to support the U.K.’s Hinkley Point C station. The move addresses funding needs left unmet since China General Nuclear Power Corporation—which originally planned to pay for one-third of the project—exited in 2023 amid U.K. government efforts to reduce Chinese involvement.

The cross section of the 58Ni(n, p)58Co reaction was determined by the activation method for neutron energies from 3 to 4.8 MeV. Neutron fluxes were measured with a laboratory-fabricated proton recoil telescope consisting of a radiator, an evacuated cell, and a surface barrier detector. The absolute efficiencies of the telescope for different neutron energies have been interpreted by Monte Carlo calculation as well as by a direct integration method. The fraction of activations induced by neutrons following single elastic scattering to those without scattering in the nickel sample was also calculated by a Monte Carlo program. The neutron attenuation through the nickel sample was also considered. Major sources of error in the cross-section determination are summarized and discussed. The total error was estimated to be 4 to 5%.
