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 neutron average total cross section of thorium has been measured near 24 keV in an accurate transmission experiment using the time-of-flight method and the iron-filtered-beam technique. The measured average total cross section is 14.933 ± 0.041 b. The computer codes BABEL and MCROSS were used to stochastically calculate average cross sections near 24 keV from several sets of resonance parameters. The average total cross section calculated from the Forman et al. data set is in good agreement with the experimental results, but the cross section calculated from the ENDF/B-IV data set is 16% lower than the measured value. The major part of this 16% discrepancy is attributed to too small a nuclear scattering radius in the ENDF/B-IV data set.
