Review of IEC/ISO international standard related to HMI design for control rooms on NPP

The improvement of Human-Machine Interface (HMI) design for control rooms on nuclear power plants (NPP) has been accomplished work wide, especially after the TMI-2 accident. The design process and guidelines are standardized in IEC60964 and supplemental standards by IEC (International Electrotechnical Commission) as international standard. On the other hand, ISO (International Standard Organization) issues ergonomic standards in HCI (Human Computer Interaction) for general industrial use. ISO11064 series are the process oriented standards specify procedures and processes to be followed. IEC60964 and supplemental standards have been effectively used and the design process required in IEC 60964 is the basis of the design process of ISO11064-1. However, IEC60964 is under revision, for example, to make technological update for taking into account the computerized control rooms, and to improve the human factor requirements. The revised version will consistent with the other IEC standards and similar standards or guidelines of another bodies. For hardware and software of computerized I and C system, a series of international standards have been systematically developed. In Japan, Japan electric association is developing industry association level guideline for the human-machine interface designs of the computerized main control rooms of nuclear power plants, as well as regulatory agencies of nuclear power plants in Japan are preparing technical basis for reviewers of control rooms of nuclear power plants. In this paper, we present the review of not only the state of international activities for revising IEC60964 and the state of ISO11064 series, but also the state and relationship to the related standards.
