摘要： A recombination apparatus is provided to an off-gas system of a boiling water nuclear plant. An off-gas system pipe connected to a condenser is connected to the recombination apparatus. A catalyst layer filled with a catalyst for recombining hydrogen and oxygen is disposed in the recombination apparatus. The recombination catalyst has a percentage of the number of Pt particles whose diameters are in a range from more than 1 nm to not more than 3 nm to the numbers of Pt particles whose diameters are in a range from more than 0 nm to not more than 20 nm, falling within a range from 20 to 100%. The condenser discharges gas containing an organosilicon compound (ex. D5), hydrogen, and oxygen, which is introduced to the recombination apparatus. Use of the above recombination catalyst can improve the performance of recombining hydrogen and oxygen more than conventional catalysts and the initial performance of the catalyst can be maintained for a longer period of time.

摘要： An object of the invention is to prevent a human error, greatly reducing man-hours and to securely identify a core. To achieve the object, a request for a serial number is first made via a conductor of a core from a recognition unit that functions as a master to a recognition unit that functions as a slave. Next, the recognition unit as the slave reads a serial number for an IC tag and transmits the serial number via the conductor of the core. The recognition unit as the master receives the serial number transmitted from the recognition unit as the slave and collates the serial number and a serial number stored in an IC tag. It is ascertained by the collation that the conduction of the core is correctly made and it is displayed on a display of the recognition unit as the master and others that no disconnection on the way and no error in selecting an end of wiring are caused.

摘要： An ultrasonic inspection method and an ultrasonic inspection device allow three-dimensional inspection data and three-dimensional shape data to be appropriately positioned on a display screen and allow a defect echo and a shape echo to be quickly identified even when information on the relative positions of a probe and an object to be inspected is not provided. The ultrasonic inspection data that is generated from the waveforms of ultrasonic waves received by an ultrasonic probe is compared with a plurality of ultrasonic propagation data pieces calculated by a ray tracing method on the basis of the three-dimensional shape data on an object to be inspected. The position of the three-dimensional inspection data or the three-dimensional shape data is moved relative to the other data position on the basis of the comparison results, thereby displaying the three-dimensional inspection data and the three-dimensional shape data while overlapping each other.

摘要： A core of a light water reactor has a plurality of fuel assemblies. The fuel assemblies include a plurality of fuel rods in which a lower end is supported by a lower tie-plate and an upper end is supported by an upper tie-plate. The fuel rods form plenums above a nuclear fuel material zone and have a neutron absorbing material filling zone under the nuclear fuel material zone. Neutron absorbing members attached to the upper tie-plate are disposed between mutual plenums of the neighboring fuel rods above the nuclear fuel material zone. The neutron absorbing members have a length of 500 mm and are positioned at a distance of 300 mm from the nuclear fuel material zone. Even if the overall core is assumed to become a state of 100% void, no positive reactivity is inserted to the core.

摘要： An electric power plant, e.g., a boiling water reactor nuclear power plant supplies steam generated in a nuclear reactor to a high-pressure turbine and a low-pressure turbine. The steam discharged from the low-pressure turbine is condensed with a condenser. Water generated with the condenser, used as feed water, flows through a feed water pipe, is heated with a low-pressure feed water heater and a high-pressure feed water heater, and then supplied to the nuclear reactor. The steam extracted from the high-pressure turbine is supplied to the high-pressure feed water heater. The steam extracted from the low-pressure turbine is compressed with a steam compressor, and the steam whose temperature has been increased is then supplied to the high-pressure feed water heater. The feed water to be directed to the nuclear reactor is heated in the high-pressure feed water heater by both the steam extracted from the high-pressure turbine and the steam compressed with the steam compressor. Because the feed water is heated by both the extracted steam and the compressed steam in the high-pressure feed water heater, the amount of plant service power consumed by the steam compressor can be reduced. Therefore, it is possible to increase thermal efficiency in the electric power plant when increasing the power output.

摘要： A steam separator comprises an outer main swirler and an inner auxiliary swirler which is smaller than the main swirler. The swirlers are provided so as to be concentric on the inner wall at the lower side of the first stage inner cylinder. In the steam separator, when the gas-liquid two-phase flow which flows in the vicinity of the axial center of the first stage inner cylinder passes the auxiliary swirler, it is separated into steam and water by the centrifugal force. The separated water (droplets) is introduced into the main swirler. When the separated water (droplets) passes the main swirler, it is separated at the inner wall side of the first stage inner cylinder by the centrifugal force.Pressure loss in a steam separator is reduced and steam separation capability is increased without increasing the moisture from the steam separator.

摘要： An ultrasonic measurement method and an ultrasonic measurement apparatus are capable of performing an inspection for a short time with a high SN ratio and a small variation (that depends on an inspection direction) in sensitivity in a process for detecting a defect in all directions at 360 degrees using a matrix array sensor without performing mechanical scanning in all directions, while reducing noise that is caused by a bottom surface echo. An element selecting circuit selects a group of a plurality of ultrasonic transducer elements for transmission from among ultrasonic transducer elements that constitute a two-dimensional array sensor so that the ultrasonic transducer elements for selected for transmission are arranged in line symmetry with respect to a first line symmetric axis to set the group selected for transmission. The element selecting circuit selects a group of a plurality of ultrasonic transducer elements for reception so that the ultrasonic transducer elements selected for reception are arranged in line symmetry with respect to a second line symmetric axis that is perpendicular to the first line symmetric axis to set the group selected for reception. A transmitting element selector selects, as transmitting elements, the ultrasonic transducer elements set by the element selecting circuit. A receiving element selector selects, as receiving elements, the ultrasonic transducer elements set by the element selecting circuit.
