    摘要: Two turning roller devices (4) are provided side-by-side in an X-axis direction along an axial position of a cylindrical container (2) to be manufactured, which is disposed in a horizontally-long orientation. Skids (5) including recessed parts (11) configured to receive the cylindrical container (2) are provided outside the two turning roller devices (4) while being supported by jack-up stands (7) including jacks (6). Each turning roller device (4) includes a function capable of changing an interval between two rollers (9). Welding work and non-destructive inspection work on the cylindrical container (2) in the circumferential direction are performed by rotating the cylindrical container in the circumferential direction on the rollers (9) with the interval decreased in each turning roller device (4). A pressure proof test is performed on the cylindrical container (2) passed from the turning roller devices (4) onto the skids (5) on the jack-up stands (7) with the interval between the rollers (9) increased in each turning roller device (4). Thereby, operation time and costs are reduced, and work quality is prevented from deteriorating due to the worsening of the working posture.

    摘要: A containment vessel (3) has an inner shell (17) covering a reactor pressure vessel (2), and also has an outer shell (18) forming an outer well (19) which is a gas-tight space covering the horizontal outer periphery of the inner shell (17). The inner shell (17) has a first cylindrical side wall (4a) which surrounds the horizontal periphery of the reactor pressure vessel (2), a containment vessel head (6) which covers the upper part of the reactor pressure vessel (2), and a first top slab (5a) which connects in a gas-tight manner the periphery of the containment vessel head (6) and the upper end of the first cylindrical side wall (4a). The outer shell (18) has a second cylindrical side wall (4b) which surrounds the outer periphery of the first cylindrical side wall (4a), and also has a second to slab (5b) which connects in a gas-tight manner the vicinity of the upper end of the second cylindrical side wall (4b) and the first cylindrical side wall (4a). In an accident of the nuclear reactor, without relying on an external power source, the release of particulate radioactive materials to the environment can be suppressed and the pressure in the containment vessel can be limited to a design pressure or below.

    摘要: A containment vessel for containing a reactor pressure vessel (2) and steam generators (3) has a main containment vessel (7), a diaphragm (9), a pressure suppression chamber (12), LOCA vent pipes (15). The reactor pressure vessel (2) contains a reactor core (1) of a pressurized water reactor. The diaphragm (9) partitions the main containment vessel (7) into an upper vessel (10) and a lower vessel (11). The pressure suppression chamber (12) has a suppression pool (13) to store water (14) and gas phase of the pressure suppression chamber (12) communicates with the upper vessel (10). The LOCA vent pipes (15) connect the pressure suppression chamber (12) to the lower vessel (11). All of the equipment and piping that constitute the reactor pressure boundary, including the reactor pressure vessel (2), the steam generators (3), a cold leg pipe (4) and a hot leg pipe (5), are contained in the lower vessel (11).
