Abstract
An in-core instrumentation system for a reactor module includes a plurality of in-core instruments connected to a containment vessel and a reactor pressure vessel at least partially located within the containment vessel. A reactor core is housed within a lower head that is removably attached to the reactor pressure vessel, and lower ends of the in-core instruments are located within the reactor core. The in-core instruments are configured such that the lower ends are concurrently removed from the reactor core as a result of removing the lower head from the reactor pressure vessel.
Claims20
A nuclear reactor plant, comprising:
- multiple nuclear reactor modules, each housing a reactor core;
- and
- a nuclear power building including multiple reactor bays each configured to house one of the multiple nuclear reactor modules, at least one refueling bay configured to disassemble and refuel the nuclear reactor modules, and a crane configured to transport the nuclear reactor modules between the reactor bays and the refueling bay.
A method for housing nuclear reactor modules within a nuclear reactor building, comprising:
- housing and operating the nuclear reactor modules in different reactor bays of the nuclear reactor building;
- operating a crane in the nuclear reactor building that transports the nuclear reactor modules between the different reactor bays and the refueling bay;
- and
- disassembling the nuclear reactor modules for refueling or maintenance in a refueling bay of the nuclear reactor building.
A nuclear reactor module, comprising:
- a reactor pressure vessel including a removably attached lower reactor vessel head configured to house a reactor core;
- and
- a containment vessel encapsulating the reactor pressure vessel and including a removably attached lower containment head configured to house the lower reactor vessel head, wherein the containment vessel and the encapsulated reactor pressure vessel are configured to be lifted and transported between a reactor bay and a refueling bay within a nuclear reactor building.
