摘要： Core debris generated during a molten reactor core in a reactor containment vessel penetrating the reactor containment vessel is configured to be caught by a core catcher located beneath the reactor containment vessel which has a main body having first stage cooling water channels and second stage surrounded by cooling fins extending radially. The number of the second stage cooling channels is larger than that of the first stage cooling channels. Cooling water is supplied from a cooling water injection opening and distributed to the first cooling water channels at a distributor. An intermediate header is formed between the first and the second cooling water channels, and the cooling water is distributed to the second cooling water channels uniformly.

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.
