Pressurised water cleaning apparatus

The above is of application in pressurised water reactor assemblies.

The invention is suitable for assemblies that are intended for pressurised water reactors.

The water-transfer device (8) for pressure water is outwardly connected with a pressure pipe (3).

The pressure in a system under pressure, in particular in the pressuriser of a pressurised water reactor, may thus be relieved even down to zero.

The invention relates to a fuel element (4) for a pressurised water nuclear reactor.

In the upper part of the pressure vessel of a pressurized-water reactor, the coolant is stored in a reservoir (10) from where it is taken out at one side and which it enters through a grid plate (5) against which the heads of the fuel elements (2) rest.

These are predominantly boiling-water and pressurized-water reactors.

A check valve for a fire hydrant system is configured to allow fluid to flow in a direction from a pressurized water supply to a fire hydrant and to restrict fluid from flowing from the fire hydrant to the pressurized water supply.

  Also provided is a reactor container (11), in which a pressurized water reactor (12) is housed.

A consaw (100) with integrated pressurised water feed is described.

All the water outlets are connected to a common pressurised water supply.

Arrangement for relieving the pressure in the safety vessel (1) of a nuclear power station with a pressurized water reactor or a boiling water reactor in the event of malfunction.

As a projection agent, compressed air or water underpressure is used for underwater working conditions.
