Abstract: EP--88572 A System for monitoring abnormal transient conditions in a pressurised water nuclear reactor installation includes a display for reactor operating parameters which has both static and dynamic display facilities. The dynamic display is continuously updated and superimposed on the static display following sequential sampling of the operating parameters. - Used for monitoring a limited number of specific operating conditions in a pressurised water nuclear reactor, such as reactor coolant system hot leg and cold leg temps. and the saturation temp. of the secondary side of the steam generator. A sequential controller continuously monitors parameters so that any transients are promptly displayed on a pressure-temp. graph. Should any of the parameters move outside a post trip window on the graph, the power platn operator can select immediately the procedure to correct the condition and bring the power plant back into normal operating range. EPAB- EP--88572 B System for monitoring abnormal transient conditions in a pressurised water nuclear reactor installation includes a display for reactor operating parameters which has both static and dynamic display facilities. The dynamic display is continuously updated and superimposed on the static display following sequential sampling of the operating parameters. - Used for monitoring a limited number of specific operating conditions in a pressurised water nuclear reactor, such as reactor coolant system hot leg and cold leg temps. and the saturation temp. of the secondary side of the steam generator. A sequential controller continuously monitors parameters so that any transients are promptly displayed on a pressure-temp. grapth. Should any of the parameters move outside a post trip window on the graph, the power platn operator can select immediately the procedure to correct the condition and bring the power plant back into normal operating range. (18pp Dwg.No.0/10) - EP--88572 B A system for monitoring abnormal transient conditions in a pressurised water nuclear reactor installation, which system comprises display means for displaying a plurality of reactor operating parameters, characterised in that the display means comprises means (12) operative to provide a static display including an area indicative of a normal pressure-temperature operating region, and means operative to provide a dynamic display representing at least one of the reactor operating parameters, which dynamic display is superimposed on the static display and falls within the static display area so long as the steam supply system of the installation is within normal operating limits thereby providing an indication of normal operation, and in that means (26) is provided for sequentially sampling the operating parameters to permit continuous updating of the dynamic display.
