Abstract

A control room for a nuclear power plant including two or more nuclear reactor units includes a central workstation providing monitoring capability for both nuclear reactor units, a first operator at the controls (OATC) workstation in front of and to one side of the central workstation providing monitoring and control capabilities for the first nuclear reactor unit, a second OATC workstation in front of and to the other side of the central workstation providing monitoring and control capabilities for the second nuclear reactor unit, and a common control workstation directly in front of the central workstation providing monitoring and control capabilities for systems serving both the first nuclear reactor unit and the second nuclear reactor unit. The central and common control workstations do not provide control capabilities for either nuclear reactor unit. The common control workstation does not include any control capabilities that must be performed by a licensed operator.

Claims (31)

1. A control room for monitoring and controlling a nuclear power plant including a first nuclear reactor unit and a second nuclear reactor unit, the control room comprising:

a central workstation providing monitoring capability for both the first nuclear reactor unit and the second nuclear reactor unit;

a first operator at the controls (OATC) workstation in front of and to one side of the central workstation providing monitoring and control capabilities for the first nuclear reactor unit but not for the second nuclear reactor unit;

a second OATC workstation in front of and to the other side of the central workstation providing monitoring and control capabilities for the second nuclear reactor unit but not for the first nuclear reactor unit;

a first manual safety panel (MSP) located to the one side of the central workstation providing safety-related monitoring information and manual controls for the first nuclear reactor unit; and

a second MSP located to the other side of the central workstation providing safety-related monitoring information and manual controls for the second nuclear reactor unit,

wherein the central workstation, the first OATC workstation, the second OATC workstation, the first MSP and the second MSP are disposed in the control room.

2. The control room of claim 1 wherein the central workstation does not provide control capabilities for the first nuclear reactor unit and does not provide control capabilities for the second nuclear reactor unit.

3. The control room of claim 1 further comprising:

a common control workstation directly in front of the central workstation providing monitoring and control capabilities for systems serving both the first nuclear reactor unit and the second nuclear reactor unit;

wherein the common control workstation is disposed in the control room with the central workstation, the first OATC workstation, and the second OATC workstation.

4. The control room of claim 3 wherein the common control workstation does not include any control capabilities that must be performed by a licensed operator.

5. The control room of claim 1 further comprising:

a common control workstation directly in front of the central workstation providing monitoring and control capabilities for common control systems defined as systems a failure of which does not require manual intervention of an OATC for at least a minimum time interval greater than or equal to one hour.

6. The control room of claim 1 further comprising an office associated with the central workstation, the office being disposed in the control room with the central workstation, the first OATC workstation, and the second OATC workstation.

7. The control room of claim 6 further comprising a conference room, the conference room being disposed in the control room with the office, the central workstation, the first OATC workstation, and the second OATC workstation.

8. The control room of claim 1 further comprising vertical panels including monitoring displays but not control inputs, the vertical panels being disposed in the control room with the central workstation, the first OATC workstation, and the second OATC workstation.

9. A nuclear power plant comprising:

a first nuclear reactor unit including a nuclear reactor core comprising fissile material disposed in a pressure vessel;

a second nuclear reactor unit including a nuclear reactor core comprising fissile material disposed in a pressure vessel; and

a control room as set forth in claim 1 .

10. The nuclear power plant as set forth in claim 9 , wherein there is a single control room and a single central workstation disposed in the control room.

11. A nuclear power plant comprising:

a first nuclear reactor unit including a nuclear reactor core comprising fissile material disposed in a pressure vessel;

a second nuclear reactor unit including a nuclear reactor core comprising fissile material disposed in a pressure vessel;

a third nuclear reactor unit including a nuclear reactor core comprising fissile material disposed in a pressure vessel;

a fourth nuclear reactor unit including a nuclear reactor core comprising fissile material disposed in a pressure vessel; and

a control room as set forth in claim 1 , wherein the control room further includes:

a third OATC workstation in front of and to the one side of the central workstation providing monitoring and control capabilities for the third nuclear reactor unit but not for the first, second, or fourth nuclear reactor units; and

a fourth OATC workstation in front of and to the other side of the central workstation providing monitoring and control capabilities for the fourth nuclear reactor unit but not for the first, second, or third nuclear reactor units;

wherein the central workstation, the first OATC workstation, the second OATC workstation, the third OATC workstation, and the fourth OATC workstation are disposed in the control room.
