The objective of this study is to support operators' work
especially in the control rooms of power plant. The
exemplified process is a pressurised water (nuclear)
reactor (PWR). The man process interface is an
information system that covers information refining,
information presentation, information system handling,
and process control. The emphasis in this study is on the
organisation and presentation of information and on the
alert function that is part of the information system.
Another goal is to design the alert function so as to
radically reduce the number of alarms during plant
shutdown, e.g. during the refuelling or maintenance
period and during a disturbance. Further, the
experimental validation of CFMS (Critical Function
Monitoring System), developed by Combustion Engineering,
Inc. in the USA is described briefly. The validation was
made at the Loviisa training simulator in the autumn of
1982. CFMS is a safety-related functional alarm system.
The functional decomposition of information has turned
out to be successful and it is helpful in designing
displays. Preliminary criteria for designing displays,
the structure of the information presentation system, and
the illustration of main interactions are presented.
General practical ideas on designing the alert function
seem very promising.
Preliminary results of the CFMS validation are presented.
Further, some ideas are presented on how to carry out the
analysis and how to make such validations in the future.
A new idea for the evaluation of core safety is
presented, based on control theory concepts.
