The specialist workshop entitled “Reactor Core and Containment Cooling Systems: Long-term Management and Reliability (RCCS-2021)” was organised by the Nuclear Energy Agency (NEA) as part of the activities of the Working Group on Analysis and Management of Accidents (WGAMA) of the Committee on the Safety of Nuclear Installations (CSNI).
The activity was co-ordinated by the French Institut de radioprotection et de sûreté nucléaire (IRSN) and attracted 188 experts from more than 28 countries representing regulatory organisations, reactor designers, operators, consultancies, engineering companies, technical support organisations (TSOs) and research establishments.
The workshop was organised as a follow-up to NEA activities on establishing a knowledge base for long-term core cooling reliability (NEA, 2013) and on the long-term management and actions for a severe accident in a nuclear power plant (NEA, 2021). It aimed at providing an update on recent developments related to practices for maintaining the core and containment cooling functions in the long term, following an accident in a nuclear power plant, with the intent of including most recent upgrades as well as lessons learnt from the Fukushima Daiichi accident.
