Marine pressurized water reactor and primary side non-kinetic waste heat removal system thereof

Abstract

The invention discloses a marine pressurized water reactor and a primary side non-kinetic waste heat removal system thereof. The primary side non-kinetic waste heat removal system of the marine pressurized water reactor comprises a water tank, a cooler and a condensation loop, wherein the water tank is arranged on the inner wall of a containment outer hull, and fresh water is stored in the water tank; the cooler is arranged in the water tank, and the position of the cooler is higher than that of a reactor pressure vessel in the vertical direction; the condensation loop comprises an output pipeline and an input pipeline; the output pipeline is used for conveying a coolant in the cooler to the reactor pressure vessel for realizing heat exchange, the input pipeline is used for conveying the coolant, subjected to heat exchange, back to the cooler for cooling. When a whole ship has a power failure accident, an electromagnetic valve is automatically opened, and a condensing agent is enabledto circulate along the condensation loop; if the electromagnetic valve is not opened accidentally, a hand valve can be opened manually, and the condensing agent is enabled to circulate along the condensation loop, so that the safety of a reactor is maintained.

Description

technical field [0001] The invention relates to a ship power system, in particular to a ship pressurized water reactor and a primary side non-kinetic waste heat discharge system thereof. Background technique [0002] The exploitation of offshore resources and the improvement of the living environment of islanders all face the problem of energy shortage. Ships equipped with small pressurized water reactors can provide safe and effective energy supply for offshore oil exploitation, and are also suitable for high-power ships and seawater desalination. New energy is of great significance. [0003] However, when the pressurized water reactor nuclear power ship loses power on board (including the loss of emergency power supply), the main pump shuts down, the coolant flow rate of the reactor pressure vessel drops sharply, and at the same time, the feedwater on the secondary side of the steam generator is lost, causing the steam generator The heat transfer capacity decreases, and t...
