An underwater electricity production module includes an elongated cylindrical casing, which includes an integrated electricity generation unit having a nuclear boiler. The generator is connected to an external electricity distribution station by electrical cables. The nuclear boiler is placed in a dry chamber of a reactor compartment associated with a chamber forming a safety water storage reservoir of the reactor. At least a radial wall of the reservoir chamber is in a direct heat exchange relationship with a marine environment that surrounds the underwater electricity production module in which the underwater electricity production module is submerged.

Submerged electricity production module

This underwater electricity production module includes an elongated cylindrical box, which includes a reactor compartment and an electricity production unit. The reactor compartment includes a reservoir chamber and a dry chamber. A nuclear reactor is located in the dry chamber. The reservoir chamber forms a safety water storage reservoir. At least a radial wall of the reservoir chamber is in a direct heat exchange relationship with a marine environment that surrounds the cylindrical box. The nuclear reactor includes a nuclear boiler which includes a pressurizer connected through a depressurizing valve to the reservoir chamber.

An underwater electricity production module includes an elongated cylindrical box, which includes a reactor compartment, which further includes a reservoir chamber and a dry chamber; an electricity production unit including a reactor container, the reactor container being placed in the dry chamber in a reactor pit having a first lower portion; and a circumferential wall including a first part delimiting the reservoir chamber, the first part being in a direct heat exchange relationship with water of the marine environment surrounding the elongated cylindrical box. The reservoir chamber has a second lower portion connected to the first lower portion through a water inlet duct placed along the circumferential wall. The reactor pit has a first upper portion connected to a corresponding portion of the reservoir chamber through a water return duct.

Electricity production module

An underwater electricity production module includes an elongated cylindrical box, which includes a reactor compartment and an electricity generator compartment. The reactor compartment includes a reservoir chamber and a dry chamber. A nuclear reactor is located in the dry chamber. The reservoir chamber forms a safety water storage reservoir. At least a radial wall of the reservoir chamber is in a direct heat exchange relationship with a marine environment that surrounds the cylindrical box. The reservoir chamber and the dry chamber can be placed in fluid connection. A seawater inlet is formed in a radial wall of the receiving compartment. A duct connects the seawater inlet to the dry chamber. A quenching valve is in the duct. Opening of the quenching valve allows the dry chamber, and thus the nuclear reactor, to be quenched with seawater.
