Abstract

A gas leak determination device according to an embodiment comprises an absolute pressure information acquisition unit, temperature information acquisition unit, temperature correction factor calculation unit, conversion unit, and determination unit. For each gas section, the absolute pressure information acquisition unit acquires absolute pressure information indicating the absolute pressure of the gas section. The temperature information acquisition unit acquires temperature information indicating a tank surface temperature. For each gas section, the temperature correction factor calculation unit calculates a temperature correction factor for correcting the temperature of the gas section on the basis of the temperature information acquired during a prescribed period and the absolute pressure information acquired during the prescribed period. The conversion unit converts the absolute pressures of the gas sections into absolute pressures at a prescribed standard temperature on the basis of the absolute pressure information and the temperature correction factors calculated by the temperature correction factor calculation unit. The determination unit determines whether there is a gas leak of insulating gas from a tank on the basis of the absolute pressures at the prescribed standard temperature that have been arrived at through conversion by the conversion unit.

Even when a radiation detector contacts a pipe arrangement or another member that is an object to be monitored, the damage of the detector is prevented without impairing the detection performance. An inside-tube-wall radioactive contamination monitor comprises: a rod-like light guide bar having a polygonal cross-section; a plurality of scintillators secured to the outer circumferential surface of the light guide bar; a net-like protective tube worn so as to cover the outer circumference of the scintillators with a space between the surfaces of the scintillators and the tube; and a guide portion attached to an end of the net-like protective tube, supporting an end of the light guide bar, and having a shape the diameter of which decreases as approaching the end. The monitor includes: a photoelectric conversion unit coupled to the base end of the net-like protective tube and incorporating a photoelectric conversion element; and a signal processing unit connected to the photoelectric conversion unit.

Abstract

Provided are a radioactive contamination monitoring device and a radioactive contamination monitoring method for enabling easy detection of radiation from an object to be monitored in a little surrounding space.  The radioactive contamination monitoring device comprises a radiation detection unit, a photoelectric conversion unit for converting the light generated in the radiation detection unit to electricity, and a signal processing unit connected to the photoelectric conversion unit.  The radiation detection unit includes a quadrangular prism-shaped light guide bar having a rectangular cross-section and a scintillator attached only to two adjacent side faces of the four side faces of the light guide bar.

Abstract

Disclosed is an installation method of equipment, wherein efficiency in installation work of equipment such as an ECCS pump is enhanced. The method comprises the steps of: preparing in advance a pit can unit, in which an upper side frame, a pit can, various reinforcing bars including longitudinal reinforcing bars for reinforcing the upper side frame and the pit can, and an anchor plate supporting mechanism are integrated; and installing the pit can unit on an MMR with a lower side frame therebetween. Furthermore, an anchor bolt unit is arranged on the anchor plate supporting mechanism after primary concrete is installed, and then relative positional relation of each foundation bolt to the pit can is corrected by using a template. Secondary concrete is installed in the state where the positional relation is corrected. Thereafter, an ECCS pump is carried into the pit can and secured through each foundation bolt having the bottom side thereof buried, thus completing installation of the ECCS pump.

Abstract

The ease with which a mobile in-core instrumentation system can be maintained is improved without hindering passage through an access tunnel which has an indexing device of a traversing in-core probe (TIP) system installed therein. An installation unit for an indexing device provided in the TIP system comprises a base on which is mounted the indexing device of the mobile in-core instrumentation system which is used in an atomic reactor; a holding unit which holds the base in the access tunnel formed inside an atomic reactor containment vessel so that the base is suspended; and a hoisting mechanism which raises and lowers the base held by the holding unit together with the indexing device.

Abstract

A penetrating hole serving as a temporarily constructed drainage facility is provided in a floor slab of a building under construction, and the penetrating hole includes a generally cylindrical funnel part opened in the floor surface of a room. A connection pipe is communicated with the bottom part of the funnel part, and a hose guide pipe is inserted into the bottom end of the connection pipe part. A flange part is so provided at the lower end part of the hose guide pipe as to be substantially flush with the ceiling surface of a room on the lower story.

Abstract

A temporary drainage facility for draining rainwater flowing into a story under construction to the outside while a building of a plurality of stories is constructed comprises flexible drain collecting hoses connected to penetrating holes formed in the floor slab of the story under construction, settling containers disposed on the floor slab of the installed floor of the building and connected to the drain collecting hoses, a drain pit which is formed on the lowermost story of the building and which accumulates the water discharged from the sand precipitation containers through drain hoses, and drain pumps installed in the drain pit. The water collected in the drain pit is discharged to the outside of the building by the drain pumps.

Abstract

A marking tool for a benchmark comprises a marking plate the upper surface of which is formed flat and on the upper surface of which a bench mark is marked, a stud which is extended from the rear surface of the upper surface of the marking plate and is buried in a structure such as the floor of a building or the like to fix the marking plate, and an outer peripheral flange which is provided around the marking plate and buried in a paint layer applied onto the structure. In such a state that the marking plate is disposed on the structure of the building, the upper surface of the marking plate is so disposed as to be equal to or lower in height level than the upper surface of the paint layer applied onto the structure.
