An offshore, floating, moored, nuclear power generating and multi-purpose platform is disclosed. In a preferred embodiment, the invention is a spar platform with multi-purpose, topside decks, attached to a submerged dry tank that further includes: reactor generator deck(s), power plant main control deck, and central plant deck, that are all integrated within a watertight ballast hull. The invention further includes cells that are modular for facilitating factory assembly and ultimate construction in a shipyard environment. Reactor vessels are typical naval nuclear reactor having a time tested outstanding safety record. A plurality of reactor generator modules operate independently and collectively. Multipurpose topside decks house vessel command, crew, and any ancillary and co-generation equipment. The present invention, constructed in a multi-path manufacturing process, provides exceptional economic, environmental, sustainability, security, safety, and operational benefits to users.

The systems and methods generally include a nuclear power plant unit assembled in a shipyard from a plurality of structural modules, each of the structural modules having manufactured components for use in power production when moored or fixed to a floor at least one of in and proximal to at least one of an offshore marine environment, a river environment and a coastal marine environment. The nuclear power plant unit is subdivided into at least one arrangement of structural modules that includes an electrical interface for one of transmitting electrical power generated by the nuclear unit and powering a system of the unit, a communications interface for communications internal or external to the unit, a user interface that is configured to permit a user to access a system of the unit, and a network interface for data communications to or from the unit.

An offshore, floating, moored, nuclear power generating plant and multi-purpose platform is disclosed herein. In a preferred embodiment, the invention consists of a spar or cell spar platform with multi-purpose, all weather topside decks, attached to a submerged dry tank that further includes: reactor generator deck(s), power plant main control deck, and central plant deck, that are all integrated within a watertight ballast hull. The invention design further includes cells that are modular for facilitating factory assembly and ultimate construction in a shipyard environment. Reactor vessels are typical naval nuclear reactor having a time tested outstanding safety record. A plurality of reactor generator modules are interconnected and operate independently and collectively and are transmitted by a plurality of high voltage direct current (HVDC) submarine cables through a transformer to the electrical grid. Multipurpose topside decks house vessel commend, crew, and any ancillary and co-generation equipment. The present invention, constructed in a multi-path manufacturing process, provides exceptional economic, environmental, sustainability, security, safety, and operational advantages over the current art of power generation.

Systems and methods for utilizing nuclear-based marine craft to generate electricity for external or grid usage are disclosed. In accordance with some embodiments, the system may include a nuclear-based marine craft having a propeller shaft and an electrical generator coupled external to the marine craft and configured to transmit generated electricity. In accordance with some other embodiments, the system may include a nuclear-based marine craft having a nuclear reactor and a turbine, a dock or barge having its own turbine and electrical generator, a steam outlet pipe connecting the nuclear reactor to the dock or barge turbine, and a steam inlet pipe connecting the dock or barge turbine back to the nuclear reactor, whereby heated steam from the nuclear reactor spins the dock or barge turbine, which then powers the electrical generator on the dock or barge to generates electricity.

Some embodiments relate to refueling a power generator installed in an integrated monopile system. A bottom end of the integrated monopile system is installed in an earthen substrate. The integrated monopile system includes a cavity containing the power generator. Refueling steps may include: installing a refueling platform over a top end of the integrated monopile system, the refueling platform comprising a crane system configurable over the cavity of the integrated monopile system; exposing the cavity of the integrated monopile system to the crane system of the refueling platform by opening a lid on or in the top end of the integrated monopile system; lowering, by the crane system, a new fuel assembly into the cavity of the integrated monopile system; separating, via the crane system, the power generator from a fuel storage container; and removing spent fuel from slots of the fuel storage container.
