Abstract
IFMIF (International Fusion Materials Irradiation
Facility) will be an accelerator-based neutron source to
test fusion candidate materials. The Engineering
Validation and Engineering Design Activities (EVEDA)
of IFMIF are aimed to deliver the complete engineering
design file of this major facility.
Achieving a high level of availability and reliability is a
key point for IFMIF mission. A goal of 70% of
operational availability has been established. In order to
fulfil the availability requirements, RAM (Reliability,
Availability and Maintainability) has to be considered
during the engineering design phase. This paper
summarizes the methodology developed and the proposed
process aimed at including RAM in the design of IFMIF,
as well as the activities performed in this framework.
Overall RAM specifications have been defined for
IFMIF project. RAM methodology dealing with RAM
design guidelines, reliability database and RAM
modelization has been developed. As a first step for the
iterative process of RAM analysis of IFMIF design, a
fault tree model based on a new reliability database has
been performed with Risk Spectrum®. The result is a first
assessment of the availability and first allocation of RAM
requirements.
