| HRA Challenges in New Nuclear Power Plant Designs |
|---|
| Digital instrumentation and control systems are being added to operating nuclear power plants (NPP), and included in the designs of the next generation of NPPs. Further, the newer advanced reactors are not only incorporating digital systems, but they are also increasing the amount of automation to improve plant safety and to decrease the reliance on human operators. In each of these cases, advancements in system design such as instrumentation, controls, automation, and data collection have significantly altered the human-machine interface. Human factors insights related to tasks, procedures, training, and allocation of functions help to improve safety and reliability. Operating experience with NPPs and other systems tells us that in addition to improvements, the design is not guaranteed to be free from errors. In order to evaluate the effectiveness of these improvements in the digital I&C systems, a human reliability analysis (HRA) as part of a risk assessment can provide insights into what is likely to go wrong and the consequences of errors. For the first generation of power plants in the USA, the risk assessment and HRA were developed after the plants were built and operating. In order to further improve the safety and reliability of new plants, an approach that combines these two disciplines during the design and pre-operational phase is recommended. This paper outlines the concept for this approach, discusses advantages and potential disadvantages of digital instrumentation, controls, automation, and data collection systems, and recommends a technology neutral approach to applying HF and HRA techniques to improve NPP safety and reliability. A number of challenges in todays’ HRA and HF processes and methods are discussed, and also the way in which these challenges might change in future new designs. |
