Abstract

A system for servicing a nuclear reactor module comprises a crane operable to attach to the nuclear reactor module, wherein the crane includes provisions for routing signals from one or more sensors of the nuclear reactor module to one or more sensor receivers.

First claim

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. A method of servicing a nuclear reactor module, comprising:
decoupling one or more sensors of the nuclear reactor module from a first signal receiver, wherein the one or more sensors are positioned within a reactor vessel of the nuclear reactor module during operation of the nuclear reactor module for monitoring one or more parameters of the operation of the nuclear reactor module;
after decoupling the one or more sensors from the first signal receiver, coupling the one or more sensors of the nuclear reactor module to a second signal receiver; and
after coupling the one or more sensors to the second signal receiver, moving the nuclear reactor module from a reactor bay to a servicing area.

2. The method of claim 1 , additionally comprising displaying a representation of at least one signal from the one or more sensors of the nuclear reactor module on a display located within the servicing area.

3. The method of claim 2 , additionally comprising displaying the representation of the at least one signal from the one or more sensors of the nuclear reactor module on a display located in a reactor operator area.

4. The method of claim 1 , wherein the coupling further comprises transmitting signals from the one or more sensors of the nuclear reactor module through a conduit located on a crane coupled to the nuclear reactor module to the second signal receiver.

5. The method of claim 1 , wherein the one or more sensors include a first sensor and a second sensor, and wherein the decoupling and coupling occur in a sensor-by-sensor manner wherein
the first sensor is decoupled from the first signal receiver and coupled to the second signal receiver, and
after the first sensor is coupled to the second signal receiver, the second sensor is decoupled from the first signal receiver.

6. A method of servicing a nuclear reactor module, comprising:
decoupling a first sensor of the nuclear reactor module from a first signal receiver;
coupling the first sensor to a second signal receiver;
comparing a signal level from the first sensor received by the first signal receiver with a signal level from the first sensor received by the second signal receiver,
after coupling the first sensor to the second signal receiver, decoupling a second sensor of the nuclear reactor module from the first signal receiver;
coupling the second sensor to the second signal receiver; and
moving the nuclear reactor module from a reactor bay to a servicing area.

7. The method of claim 6 , wherein decoupling the second sensor from the first signal receiver includes decoupling the second sensor after determining that the signal level from the first sensor received by the first signal receiver approximates the signal level from the first sensor received by the second signal receiver.

8. The method of claim 1 , further comprising continuously monitoring the nuclear reactor module during the moving using the second signal receiver.

9. A method of servicing a nuclear reactor module, comprising:
decoupling one or more sensors of the nuclear reactor module from a first signal receiver, wherein the first signal receiver is connected to a reactor bay interface panel proximate a reactor bay, and wherein the one or more sensors are positioned within a reactor vessel of the nuclear reactor module during operation of the nuclear reactor module for monitoring one or more parameters of the operation of nuclear reactor module;
after decoupling the one or more sensors from the first signal receiver, coupling the one or more sensors of the nuclear reactor module to a second signal receiver, wherein the second signal receiver is connected to a crane interface panel attached to a crane for movement together with the crane; and
after coupling the one or more sensors to the second signal receiver, moving the nuclear reactor module, by using the crane, from the reactor bay to a servicing area.

10. The method of claim 9 , wherein decoupling the one or more sensors comprises disconnecting a cable from the reactor bay interface panel, the cable having a connector at an end of the cable external to the nuclear reactor module, the cable operable to convey signals from the one or more sensors located within the nuclear reactor module, the cable further being selectively attachable to and detachable from the reactor bay interface panel.

11. The method of claim 9 , wherein the crane interface panel is operable to accept the one or more signals from the one or more sensors within the nuclear reactor module when the one or more sensors are decoupled from the reactor bay interface panel and coupled to the crane interface panel.

12. The method of claim 9 , wherein decoupling the one or more sensors comprises disconnecting a cable from the reactor bay interface panel, the cable having a connector at an end of the cable external to the nuclear reactor module, the cable operable to convey signals from the one or more sensors located within the nuclear reactor module, the cable further being selectively attachable to and detachable from the reactor bay interface panel, and further wherein the crane interface panel is operable to accept the one or more signals from the one or more sensors within the nuclear reactor module when the cable is disconnected from the reactor bay interface panel and attached to the crane interface panel.

13. The method of claim 12 , wherein when the cable is detached from the reactor bay interface panel and attached to the crane interface panel, the connector and the crane interface panel move together with the crane when the crane is operating to move the nuclear reactor module.

14. A method of servicing a nuclear reactor module, comprising:
terminating signal communication between one or more sensors of the nuclear reactor module and a first signal receiver, the first signal receiver being provided in a first interface panel positioned proximate a reactor bay, and wherein the one or more sensors are positioned within a reactor vessel of the nuclear reactor module during operation of the nuclear reactor module for monitoring one or more parameters of the operation of the nuclear reactor module;
after terminating the signal communication between the one or more sensors and the first signal receiver, initiating signal communication between the one or more sensors of the nuclear reactor module and a second signal receiver, the second signal receiver being provided in a second interface panel, the second interface panel being attached to a device operable to move the nuclear reactor module; and
after initiating the signal communication between the one or more sensors and the second signal receiver, moving the nuclear reactor module together with the second interface panel from the reactor bay to a servicing area.

15. The method of claim 14 , wherein terminating the signal communication between one or more sensors comprises disconnecting a cable from the first interface panel.

16. The method of claim 15 , wherein the cable includes a connector at an end of the cable external to the nuclear reactor module, the cable operable to convey signals from the one or more sensors located within the nuclear reactor module, the cable further being selectively attachable to and detachable from the first interface panel.

17. The method of claim 16 , wherein initiating the signal communication between the one or more sensors comprises connecting the cable to the second interface panel.

18. The method of claim 17 , wher
