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 capture cross sections of 240Pu and 242Pu were measured in the energy range from 10 to 90 keV. The capture cross sections of both 197Au and 238U were chosen as standards. Neutrons were produced via the 7Li(p,n) reaction with the Karlsruhe 3-MV pulsed Van de Graaff accelerator. Capture events were detected by a Moxon-Rae detector. The high neutron flux available at flight paths as short as ∼10 cm offers a signal-to-background ratio one order of magnitude better than obtained in previous experiments. The cross-section ratios could therefore be determined with a total statistical and systematic uncertainty of 4 to 10% for 240Pu and 6 to 10% for 242Pu. The results agree with previous data, while discrepancies to the evaluated files ENDF/B-IV and KEDAK 3 were found (up to 30% for 240Pu and up to 50% for 242Pu).
