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
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.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

The JET Active Gas Handling System (AGHS) consists of a number of interlinked processing systems for recovery of the radioactive tritium, its purification, separation from the other hydrogen isotopes, storage and recycling to the JET machine. To meet the stringent safety requirements and the multiplicity of monitoring, control and operational tasks, a plant-wide process control system was designed to integrate all tritium related functions. The AGH Control system is based on an industrial Distributed Control System (DCS) by Fischer & Porter which was tailored to the specific sequential/batch, closed loop and coordinating needs of the plant. Approximately 3600 Input Output (I/O) points are interfaced to the front-end consisting of 16 processors linked via a dual Ethernet Highway network and fast (0.1 s) 4-loop controllers. Three identical console processors support 6 screens which can access any point of the plant. The system has data-links to PLC's, analytical instrumentation and the JET CODAS network. It was installed in a dedicated control room in 1990 and is now being tested and commissioned. This paper describes the design of the system, the selection of the DCS hardware and the special emphasis which was put on the preparation of the software requirements and documentation.
