ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

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 singular-eigenfunction-expansion method and the principle of invariance are combined to reduce the two-half-space Milne problem to a regular computational form in the two-group isotropic scattering model. The method used here consists in considering a problem of two contiguous half-spaces with surface sources at the interface. The problem is equivalent to the Milne problem in the sense that the expansion coefficients are to be determined from the same equation. The emergent distributions are obtained from coupled regular integral equations. The expansion coefficients can then be obtained using the halfrange orthogonality relation of the eigenfunctions. Numerical results are reported for light-water media.
