  IFMIF will be an ac­cel­er­a­tor-based neu­tron source to test fu­sion can­di­date ma­te­ri­als. The En­gi­neer­ing Val­i­da­tion and En­gi­neer­ing De­sign Ac­tiv­i­ties 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 ful­fill the avail­abil­i­ty re­quire­ments, RAM 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.
