Specifies functional analysis and assignment procedures (FA and A, sometimes calles allocation of functions) for the design of the control-room system for nuclear power plants and gives rules for developing criteria for the assignment of functions. Supplementary to IEC 60964, which applies to the design of the control-room for nuclear power plants. Provides specific requirements to carry out functional analysis and assignment required in 3.1 and 3.2 of IEC 60964, and therefore supersedes the guidance given in A.3.1 and A.3.2 of IEC 60964. Applies to the design of new control-rooms or backfits to existing control-rooms.
