    摘要: According to an embodiment, a pressurized water reactor plant has a primary system which includes: a reactor vessel for housing a reactor core which is cooled by a primary coolant, a single steam generator, a hot leg pipe for connecting the reactor vessel and the steam generator, cold leg pipes, at least two primary coolant pumps, and a pressurizer for pressurizing the primary coolant pressure boundary in which the primary coolant flows. The plant also has: a passive cooling and depressurization system which is a primary depressurization means for equalizing the primary system pressure to the secondary system pressure at the time of a tube rupture accident of the steam generator, and a reactor containment vessel containing the primary system and cooling the primary system by air cooling. Thus, a compact pressurized water rector with high economic efficiency, safety, and reliability can be provided.

    摘要: Illumination devices (7a) and (7b) which irradiate light having a wavelength of 1.1 μm or less are arranged on a front surface and a rear surface of a cover (8) of a dicing device (1). After a wafer is placed on a dicing stage (3), when the wafer is diced by a blade (4a) attached to a spindle (5), light is irradiated on an entire surface of an upper surface (element forming surface) of the wafer by the illumination devices (7a) and (7b). At this time, an illuminance of light on the wafer is set at 70 lux or more and 2000 lux or less. By this means, during a dicing operation, an area to be a light-shielded area by the spindle (5) or the like is not present on the wafer.

    摘要: A containment vessel has an inner shell covering a reactor pressure vessel and an outer shell forming an outer well which is a gas-tight space covering the horizontal outer periphery of the inner shell. The inner shell has a first cylindrical side wall surrounding the horizontal periphery of the reactor pressure vessel, a containment vessel head which covers the upper part of the reactor pressure vessel, and a first top slab connecting in a gas-tight manner the periphery of the containment vessel head and the upper end of the first cylindrical side wall. The outer shell has a second cylindrical side wall surrounding the outer periphery of the first cylindrical side wall, and also has a second to slab connecting in a gas-tight manner the vicinity of the upper end of the second cylindrical side wall and the first cylindrical side wall.
