Embodiment Construction

[0056] figure 1The lower part of the steam generator is shown in , denoted by reference numeral 1 , which comprises the hemispherical wall of the water tank 2 . This hemispherical wall is welded to the tubular plate 3 in which the ends of the tubes in the manifold 4 are connected. The inside of the water tank 2 is divided into two parts by a diaphragm 5 .

[0057] On each side of the partition 5 , the wall of the tank 2 is pierced with an opening, at which a pipe 6 is connected to connect the two lines of the primary circuit (not shown).

[0058] With the tube 6 it is possible to ensure the supply of pressurized water to one part of the tank and the other part of the tank to recover the pressurized water that has circulated inside the tube in the manifold 4 of the steam generator 1 .

[0059] The walls of the tank 2 are also pierced with manholes 7 leading to each compartment separated by partitions 5 . Such as figure 2 As seen in , the pipe 6 connected at the opening thr...

Abstract

The invention relates to a sealed stopper (10) for an opening in a junction tubing (6) between a housing and a pipe that comprises a fixation ring. The stopper (10) includes a rigid lid (11) and a sealing assembly (20) carried by said lid (11) including a passive annular seal (25) with at least one inner annular chamber (26), a first static annular seal (30), a second static annular seal (35), and a flat annular seal (40) ensuring the tightness of the opening in said tubing.

Description

technical field [0001] The present invention relates to a sealing plug for an opening in a junction pipe between a vessel and a pipeline, and more particularly, the present invention relates to a sealing plug for connecting a water tank of a steam generator of a pressurized water nuclear reactor to one end of a primary circuit A sealing plug for the opening of the tube. [0002] The invention also relates to a method of sealing an opening in a junction pipe between a container and a pipeline by means of such a plug. Background technique [0003] Pressurized water nuclear reactors include steam generators that ensure that the feed water is warmed and vaporized by the heat transferred by the pressurized water used to cool the reactor core. [0004] A pressurized water reactor includes a steam generator on each of its main branches. The steam generator has a main section through which pressurized water circulates to cool the reactor, and a secondary section that receives feedw...
