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.

Framatome signs contracts with Sizewell C
French nuclear developer Framatome is slated to deliver key equipment for Sizewell C Ltd.’s two large reactors planned for the United Kingdom’s Suffolk coast.
The agreement, reportedly worth multiple billions of euros, was announced this week and will involve Framatome from the design phase until commissioning. The company also agreed to a long-term fuel supply deal. Framatome is 80.5 percent owned by France’s EDF and 19.5 percent owned by Mitsubishi Heavy Industries.

A general physical approach and simplified algorithm have been developed that allow utilities to choose their strategy for treatment of the most dangerous long-lived fission products (either to incinerate under neutron flux or to store in underground repository) as well as to assess the overall neutron consumption needed for their incineration in a fast neutron spectrum. It has been demonstrated that if nuclear power can solve transuranic (TRU) waste transmutation problems and be able to incinerate the most toxic long-lived nuclides, such as Tc, I, and Cs (it demands ~0.15 n/fission for all these nuclides without isotopic separation), then the long-term radiotoxicity in the underground repository will not exceed the initial radiotoxicity of uranium fuel. This is one of the most important criteria of the radiologically clean nuclear power concept. Hence, apart from TRU transmutation problems, the emphasis is now on long-lived fission product incineration.
