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.

We had first developed APR1400 simulator with the form of emulation to perform HFE V&V of the MMIS in the construction phase of Saewool 1&2 nuclear power plant. And then APR1400 simulator was developed gradually reflecting design change and transformed into the APR1400 training simulator, and finally contributed to the acquisition of the operating license. But if MMIS related problem or MMIS design change happens in the digitalized MMIS in the plant operation phase, we need to perform MMIS V&V including control logic and MMI function through the most similar testbed. But plant MMIS cannot be fully tested with the limited condition of the emulated simulator. We have come up with new method to perform operator training and MMIS V&V simultaneously. Accordingly, we adopted virtual Distributed Control System (DCS) to implement plant MMIS in the APR1400 training simulator. This virtual DCS has the same control logic and MMI function as plant is provided. Three types for simulator operation will be provided. First mode is hybrid mode which is implemented with the form of emulated MMI and real plant control logic implemented with virtual DCS for operators’ training as well as control logic V&V. Second mode is emulation mode which is implemented with the form of emulated MMI and control logic. Final mode is stimulation mode which is fully implemented with the form of real plant MMIS including control logic and MMI function. This approach provides opportunity that complex control logic such as NSSS Process Control System can be validated before real control logics are applied in plant MMIS and improves coping capability of operator due to operator’s training in the same environment as plant. Application of this method can reduce plant transient state and unexpected plant event through the resolution of MMIS fault in advance.
