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.

Kentucky legislature sends nuclear bills to governor
Kentucky’s Republican-majority legislature passed a bill this past week that could bring nuclear energy to the “coal-is-king” state as lawmakers broadly seek solutions to reduce carbon emissions. The bill went to Democratic Gov. Andrew Beshear on Monday for final approval.

As an important means of safety research in nuclear power plant, thermal hydraulic test verification has attracted the attention of many countries such as United States, Russia, France, Japan, South Korea and other advanced countries in nuclear field. In the 30 years of research and development of nuclear power plants in China, a large number of thermal hydraulic tests have been carried out. This article investigated the thermal hydraulic test facilities and China's thermal-hydraulic overall effect tests. China's three major nuclear power groups have built and operated several thermal hydraulic verification test facilities, but the objects and contents of these test facilities are targeted only for specific reactor types, and there are deficiencies in the systematization and universality of thermal hydraulic verification capabilities. Some universities in China have also carried out thermal hydraulic verification of some nuclear power plants. However, these types of test facilities are small in size and are not suitable for engineering verification. Therefore, in terms of test facilities in China, we still need to design and construct test facilities that can both meet the need of the active and passive systems, and make up the inadequacies of the thermal hydraulic verification of the primary loop system and the safety system.
