3.3 auxiliary control <operating> systems operating systems that are installed outside the control room such as local-to-plant control points and local-to-plant shutdown systems 3.4 control room staff group of plant personnel stationed in the control room, which is responsible for achieving the plant operational goals by controlling plant through human machine interfaces Note 1 to entry: Typically, the control room staff consists of supervisory operators, and operators who actually monitor plant and plant conditions and manipulate controls but also may include those staff members and experts who are authorized to be present in the control room, e.g. during long lasting event sequences. 3.5 control room system integration of the human-machine interface, the control room staff, operating procedures, training programme, and associated facilities or equipment which together sustain the proper functioning of the control room 3.6 controls devices which the operator uses to send demand signals to control systems and plant items Note 1 to entry: Controls as defined in this document (i.e. devices used for control actions) hold a different meaning from the one defined in the IAEA safety Glossary and are not replaceable. 3.7 design basis accident postulated accident leading to accident conditions for which a facility is designed in accordance with established design criteria and conservative methodology, and for which releases of radioactive material are kept within acceptable limits [SOURCE: IAEA Safety Glossary, 201 6] 3.8 design extension conditions postulated accident conditions that are not considered for design basis accidents, but that are considered in the design process of the facility in accordance with best estimate methodology, and for which releases of radioactive material are kept within acceptable limits. Design extension conditions include conditions in events without significant fuel degradation and conditions with core melting
3.1 2 functional analysis examination of the functional goals of a system with respect to available manpower, technology, and other resources, to provide the basis for determining how the function may be assigned and executed 3.1 3 functional goal performance objectives that shall be satisfied to achieve the corresponding function 3.1 4 hierarchical goal structure relationship between a functional goal and sub-functional goals structured in a hierarchical order 3.1 5 high-level mental processing human act to process and/or interpret information to obtain reduced abstract information 3.1 6 human-machine interface interface between operating staff and I&C system and computer systems linked with the plant. The interface includes displays, controls, and the Operator Support System interface 3.1 7 I&C system system, based on E/E/PE items, performing plant I&C functions as well as service and monitoring functions related to the operation of the system itself Note 1 to entry: The term is used as a general term which encompasses all elements of the system such as internal power supplies, sensors and other input devices, data highways and other communication paths, interfaces to actuators and other output devices. The different functions within a system may use dedicated or shared resources. Note 2 to entry: The elements included in a specific I&C system are defined in the specification of the boundaries of the system. Note 3 to entry: According to their typical functionality, IAEA distinguishes between automation and control systems, HMI systems, interlock systems and protection systems.

3.1 8 job set of tasks which are operationally related. The tasks within a job should be coherent with regard to required skill, knowledge and responsibility 3.1 9 job analysis analysis identifying basic requirements which a job imposes on the control room staff structure, the operating procedures and training programme 3.20 local control points local control facilities points (or facilities) located outside the control room where local operators perform control activities 3.21 local operators operating staff that perform tasks outside the control room 3.22 operating procedures set of documents specifying operational tasks it is necessary to perform to achieve functional goals 3.23 operating staff plant personnel working on shift to operate the plant Note 1 to entry: The operating staff includes the control room staff, maintenance engineers, etc.
