The NEA Specialist Workshop on Advanced Measurement Method and Instrumentation for Enhancing Severe Accident Management in a Nuclear Power Plant addressing Emergency, Stabilisation and Long-term Recovery Phases (SAMMI-2020) was held online from 7 to 9 December 2020 and hosted by the Japan Atomic Energy Agency (JAEA). Considering lessons learnt from severe accidents (SAs) that have occurred in commercial nuclear power plants, this workshop aimed to gather and summarise advanced measurement methods and instrumentation dedicated to severe accident management (SAM) at nuclear power plants, along with revised SA guidance based on instrumentation survivability insights in order to prevent, mitigate and recover from SAs in existing and future nuclear power plants. The workshop considered further advanced measurement methods and instrumentation that are necessary for long-term recovery phases to prepare for the decommissioning of an SA-damaged nuclear power plant.
