Ongoing initiatives in the nuclear industry seek to enhance the safety and improve the economic competiveness of existing nuclear power plants. These initiatives include efforts on developing Accident Tolerant Fuel (ATF), Diverse and Flexible Coping Strategy (FLEX), extending the Terry Turbine Systems (i.e., Reactor Core Isolation Cooling [RCIC]/Turbine-Driven Auxiliary Feedwater [TDAFW]) Operating Band, and the development of the passive cooling systems (e.g., the Dynamic Natural Convection [DNC] system being developed by NuVision and DYNAC Systems). All of these have the potential to offer longer time windows (i.e., coping time) for operator mitigating actions, and better human reliability to implement required actions during plant abnormal operation or severe accident conditions. Longer coping time should permit effective utilization of the FLEX equipment and accompanying mitigating strategies during postulated events. The collective changes resulting from these initiatives aggregately contribute to plants that are more resilient to off-normal events. The benefits of enhanced resilient plants are envisioned to be the following:
The safety and risk benefits of these technologies have to be quantified such that the investment on these technologies can be monetized in order to achieve cost reduction. Various efforts are going on in the national labs, academia, and the industry to quantify the risks and benefits of these technologies. Since different approaches, assumptions, data, and computer codes are used by different stakeholders, the evaluation of these technologies may result in varied conclusions in terms of the expected risk reduction and safety and economics improvements. Consequently, there is a need to "harmonize" the analysis methods wherever possible.
The primary objectives of this workshop will be to:
The expected outcome of this workshop is a characterization and understanding of methods and modeling approaches that will contribute to the enhanced resilience of NPPs and permit plant operators to enhance safety and economic performance.
The specific topics to be covered in this workshop include the following:
