Abstract: The invention provides an accumulator which can reduce the number of the parts of the pressure fluctuation absorption mechanism at the liquid expanding time, can simplify assembling and can reduce a cost of the parts. The accumulator has a seal holder which is provided in a bellows cap, and a plate-like seal which is retained by the seal holder. The seal holder is provided with an inward flange-like outer peripheral side engagement portion, and the seal is provided with an outward projection-like inner peripheral side engagement portion which is arranged in an outer peripheral surface of a seal main body and is made of a rubber-like elastic body engaging with the outer peripheral side engagement portion. The bellows cap moves to a position where liquid pressure and gas pressure are balanced with the seal seating on a seat surface due to difference in pressure receiving area.

Abstract: A method of shutting down a nuclear reactor may include compressing a scram gas that is in fluid communication with a scram accumulator. The scram accumulator defines a chamber therein and contains bellows within the chamber. The bellows are configured to hold a scram liquid in isolation of the scram gas. The scram gas exerts a compressive force on the bellows in a form of stored energy. The method may additionally include releasing the stored energy in response to a scram signal such that the scram gas expands into the chamber of the scram accumulator to compress the bellows and expel the scram liquid from the scram accumulator to insert control rods into a core of the nuclear reactor.

Abstract: In an accumulator having an accumulator housing which is provided with an oil port connected to a pressure piping of equipment, and an inner portion of the accumulator housing being sectioned into a gas chamber filling with gas and a fluid chamber communicating with the oil port by a bellows and a bellows cap, the bellows cap seals the fluid chamber by coming into contact with a seal on the basis of movement in a stroke in the case that a pressure of the pressure piping is decreased, and the seal is retained by a seal retaining portion which is provided in an inner peripheral side of the seal. In the accumulator, a seal diameter of the seal is set to be larger than an effective diameter of the bellows at a position where the seal comes into contact with the bellows cap.

Abstract: An accumulator has a seal member retained to a port hole side of a bellows cap via a seal holder. The seal member comes into contact with a seal portion so as to occlude a liquid chamber in the case that an operation of a device stops and the pressure within a pressure piping is lowered. The seal member moves in a direction that the bellows cap moves away from the seal portion while being in contact with the seal portion when the liquid confined in the liquid chamber thermally expands in a state in which the liquid chamber is occluded. The seal member is obtained by attaching a flexible portion constructed by a rubber-like elastic body to an outer peripheral surface of a rigid plate, and the flexible portion allows relative movement of the bellows cap by shear deformation on the basis of engagement with the seal holder.

Abstract: In order to provide an accumulator equipped with an emergency safety mechanism that is capable of being activated at a lower pressure than when a rupture disk is disposed on part of the circumference of the peripheral surface of a stay, the accumulator has an emergency safety mechanism that immediately releases pressure inside a housing to an oil port side when the inside of the housing reaches a high temperature and high pressure in an emergency such as a fire. The emergency safety mechanism allows a fluid chamber and the oil port to communicate via a first pressure release flow passage, which is formed due to a seal holder provided with recesses and projections on part of the circumference being seated on a seating surface, and a second pressure release flow passage formed due to a rubber-like elastic body of the seal disappearing as a result of the high temperature.
