RAMI Approach for ITER

ITER is an experimental nuclear device with an ambitious scientific and technological programme. To be able to reach its objectives an assessment of the technical risks has to be performed. The RAMI approach is one of the main stages of the technical risk control and it focuses on the operational functions required by the operation of ITER rather than on physical components. The ITER RAMI Process presented in this document, along with elements of the analysis performed on the Tokamak Cooling Water System provided as examples, consists of four major steps: (1) performing functional analysis, (2) analyzing initial failure modes, effects and criticality, (3) initiating risk mitigation actions to ensure compatibility with RAMI objectives, (4) integrating as RAMI requirements.
