## Abstract

An advanced control room complex for a nuclear power plant, including a discrete indicator and alarm system (72) which is nuclear qualified for rapid response to changes in plant parameters and a component control system (64) which together provide a discrete monitoring and control capability at a panel (14-22, 26, 28) in the control room (10). A separate data processing system (70), which need not be nuclear qualified, provides integrated and overview information to the control room and to each panel, through CRTs (84) and a large, overhead integrated process status overview board (24). The discrete indicator and alarm system (72) and the data processing system (70) receive inputs from common plant sensors and validate the sensor outputs to arrive at a representative value of the parameter for use by the operator during both normal and accident conditions, thereby avoiding the need for him to assimilate data from each sensor individually. The integrated process status board (24) is at the apex of an information hierarchy that extends through four levels and provides access at each panel to the full display hierarchy. The control room panels are preferably of a modular construction, permitting the definition of inputs and outputs, the man machine interface, and the plant specific algorithms, to proceed in parallel with the fabrication of the panels, the installation of the equipment and the generic testing thereof.

## Claims

### Claim 1

A method for installing a multi-panel, computer driven console in the control room of a nuclear power plant in which a plurality of major plant functions are performed, at least two of the panels having plant-specific algorithms for processing plant operating parameters and distinct indicator, alarm and control system man-machine interfaces pertaining to a respective two major plant functions comprising the steps of:
(a) installing at least two generic panels in the control room, wherein each generic panel includes a generic hardware configuration and a generic software configuration which has generic parameter processing algorithms, which together define a generic man-machine interface for each of said at least two major plant functions;
(b) testing the generic panels with test parameters to confirm the interaction of the generic hardware configuration with the generic software configuration;
(c) outside the control room and in parallel with at least one of the steps (a) and (b), preparing a plant specific software configuration which has plant specific parameter processing algorithms;
(d) after steps (b) and (c), integrating the plant specific software configuration with the generic panels in the plant control room to define final panels; and
(e) testing the final panels to confirm the interaction of the generic hardware configuration with the plant specific software configuration, which together provide the plant-specific man-machine interface.

### Claim 2 (depends on 1)

The method of claim 1, wherein the generic hardware configuration includes substantially vertical wall means having cut-outs, and step (a) includes installing a display screen device in each cut-out and connecting computer means to the display screen devices for processing and displaying digitized data on the display screen devices.

### Claim 3 (depends on 2)

The method of claim 2, wherein step (b) includes interactively generating images on said display screen devices in response to variations in the test parameters.

### Claim 4 (depends on 2)

The method of claim 2, wherein the step (a) is preceded by the step of fabricating each panel wall with the same number and size of said cut outs.

### Claim 5 (depends on 4)

The method of claim 4, wherein the alarm system interfaces include the display of a multiplicity of alarm tile and the indicator system interfaces includes the display of a multiplicity of operating parameter values; and
the step (d) of integrating includes employing screens dedicated to display the alarm tile of the plant-specific alarm system in wall cut-outs that are the same size as the cut-outs containing screens dedicated to displaying operating parameter values in the plant-specific indicator system.
