1 Scope
This document establishes requirements for the human-machine interface in the main
control rooms of nuclear power plants. The document also establishes requirements
for the selection of functions, design consideration and organization of the human-machine interface and procedures
which are used systematically to verify and validate the functional design. These
requirements reflect the application of human factors engineering principles as they
apply to the human-machine interface during plant operational states and accident conditions (including design basis and design extension conditions), as defined in IAEA SSR-2/1 and IAEA NP-T-3.16. This document does not cover special
purpose or normally unattended control points, such as those provided for shutdown
operations from outside the main control room or for radioactive waste handling, or
emergency response facilities. Detailed equipment design is outside the scope of this
document.
The primary purpose of this document is to provide functional design requirements
to be used in the design of the main control room of a nuclear power plant to meet
operational and safety requirements. This document also provides functional interface
requirements which relate to control room staffing, operating procedures, and the training programmes which, together with the human-machine interface, constitute the control room system.
This document is intended for application to new control rooms whose conceptual design
is initiated after the publication of this document. If it is desired to apply it
to an existing control room, special caution must be exercised so that the design
basis is kept consistent.
