A well-known regulatory requirement is to ensure the presence of a sufficient number of qualified workers. The industry has been successful in defining and maintaining adequate staffing to meet the requirements to deal with design basis situations. However, beyond design basis situations present additional challenges related to the novelty and unpredictability of at least some aspects of the situation, as well as to their potential complexity and level of risk. While the “number” aspect of the required staff is important, the “competency” aspect for beyond design basis situations deserves particular attention. Historically, individual competency profiles, both technical and non-technical, have been defined based on predictable conditions. It is however unclear if additional or different competencies are required to handle beyond design basis situations. Further, additional questions exist regarding the design of the supporting training apparatus and strategy that will be used to increase a group’s resilience in those adverse conditions.
