How are nuclear submarine reactors cooled?

The hot water from the reactor heats a separate water circuit in the steam generator. That water is converted to steam and passes through steam driers on its way to the steam turbine. Spent steam at low pressure runs through a condenser cooled by seawater and returns to liquid form.

What is the purpose of coolant coolant pumps in a nuclear reactor?

The purpose of the reactor coolant pump is to provide forced primary coolant flow to remove and transfer the amount of heat generated in the reactor core. Nuclear power plants rely on cooling systems to ensure safe, continuous operation of the nuclear reactor.

Which metal is used as coolant in nuclear reactor?

Boron, often in the form of boric acid or sodium borate, is combined with water — a cheap and plentiful resource — where it acts as a coolant to remove heat from the reactor core and transfers the heat to a secondary circuit.

How much coolant does a nuclear reactor need?

High-temperature gas-cooled reactors In both variants, the coolant consists of helium pressurized to approximately 100 bars, or roughly 100 standard atmospheres.

What is the function of the coolant removal pump in nuclear reactors?

This pump removes the heat of the primary reactor coolant after the reactor is stopped and lowers its temperature. Also, it prevents expansion of the trouble at the time of the trouble of the coolant loss by injecting boric acid of the fuel replacement water pump into the reactor core.

What is a seawater pump in a nuclear power plant?

This pump has the intermediate characteristics of two lines, the primary reactor coolant and the seawater pump, and even if the primary reactor coolant leaks, it prevents radioactive water from being discharged outside. This pump sends water to each of the following equipment and cools them.

How does a nuclear power plant cool the reactor?

Pump for continuous re-circulation of nuclear furnace coolant (light water) to the steam generator to cool the thermal energy generated by the nuclear power At the time of the trouble of the primary cooling water loss or when the main steam pipe is broken, the reactor core is urgently cooled and boric acid is urgently injected.

What happens when the steam pipe breaks in a nuclear reactor?

At the time of the trouble of the primary cooling water loss or when the main steam pipe is broken, the reactor core is urgently cooled and boric acid is urgently injected. As a result, the reactor core is cooled and the fuel rod is kept in the allowable temperature.
