摘要： An improved position detecting apparatus for detecting the position of an underwater moving body loaded with an inspecting device is provided. The apparatus is such that it makes it possible to perform inspection of a structure in water quickly, reliably and with high precision. The improvements reside in that the apparatus comprises a light source and a corner cube mounted on the underwater moving body in combination to serve as a target, a follower device, which includes a visual sensor for catching light emitted from the light source, for automatically following the target, an underwater argon laser length measuring instrument for measuring a distance between a length measuring head integrated with the visual sensor and the corner cube, and a detector device for detecting the position of the underwater moving body on the basis of an azimuth angle of the target obtained by the follower device, a reference of one side of a triangle and the measured distance.

摘要： The present invention is a transport system for an inspection system that includes a flexible controller end effector for carrying inspection and gripping devices. The transport system includes a hollow flexible conduit through which control cables for the effector can pass unobstructed. A rotatable deflector assembly helps guide the end effector as it enters the steam generator using a rotatable deflector channel and an extension. A drive assembly provides axial movement control for the end effector allowing easy insertion and retrieval. The axial movement is provided by friction rollers coupled to an axial drive mechanism and mounted in a drive box. The drive assembly also provides orientation control to allow the end effector to be rotated by rotating the drive box which rotates the conduit held in place by the direction rollers. The drive assembly further provides two spatially fixed locations from which the axial and rotational motions can be provided. The flexible conduit is taken up from and gathered by a conduit basket outside the steam generator. The conduit basket includes a control assembly for controlling the end effector via the control cables passing through the hollow conduit.

摘要： An ultrasonic inspection system is disclosed having a skate remotely controlled from a main console for positioning an ultrasonic transducer. A transmission line is used to couple drive pulses from the main control console to the transducer. Each drive pulse is generated at the console by timing means for firing a first silicon-controlled rectifier (SCR) to discharge a precharged capacitor into the line, and for firing a second SCR to shunt discharge current from the capacitor to ground. The line is terminated at its input end by its characteristic impedance. The length of the line may be changed without requiring any change at the transducer or the pulse generating circuit, except that the size of the precharged capacitor may be varied to assure delivery of a pulse of desired amplitude to the transducer.

摘要： A nuclear reactor assembly includes a reactor pressure tank having a substantially cylindrical side wall surrounded by the wall of a cylindrical cavity formed by a biological shield. A rotative cylindrical wall is interposed between the aforesaid walls and has means for rotating it from outside of the shield, and a probe is carried by the rotative wall for monitoring the pressure tank''s wall. The probe is vertically movable relative to the rotative cylindrical wall, so that by the probe''s vertical movement and rotation of the rotative cylinder, the reactor''s wall can be very extensively monitored. If the reactor pressure tank''s wall fails, it is contained by the rotative wall which is backed-up by the shield cavity wall.

摘要： A remotely controlled method for the non-destructive inspection of the primary pressure containment means of a nuclear reactor, on the site of use, for the detection of degradation resulting from sustained exposure to radiation. This method utilizes dual probes operating on a send-and-receive basis, wherein an ultrasonic beam is sent into a thick vessel wall describing a Vlike path in the same. The transducers are fixed with respect to each other, and are transported about a programmed course in fixed relation to the vessel, so as to allow the beam to inspect 100 percent of the steel in such wall. If a defect was present in the steel, it would interfere with the path of the ultrasonic beam and a corresponding loss of energy would be detected and recorded. A comparison of the record of signals resulting from this inspection, with an established pattern of signals having its inception prior to service would indicate the initiation and propagation of a defect so that, if necessary, remedial procedures could be undertaken.

摘要： A nozzle repair method and a nuclear reactor vessel include: removing a trepanning portion (208) as a connection portion with respect to an in-core instrumentation cylinder (204) in a groove-welding portion (206); removing the in-core instrumentation cylinder (204) from a semi-spherical portion (66) as a lower end plate; forming a surface buttered-welding portion (210) by buttered-welding the surface of the groove-welding portion (206); forming a welding groove (212) by grooving the surface buttered-welding portion (210); inserting a new in-core instrumentation cylinder (204A) provided with a circumferential groove portion (204f) outside an instrumentation equipment guide passage (204d) into an attachment hole (203); and fixing the new in-core instrumentation cylinder (204A) by groove-welding the welding groove (212). Accordingly, since the nozzle welding area is suppressed to a predetermined range, the workability of the repair is improved.

摘要： A regulator apparatus for distributing a fluid may include a charging valve assembly and a flow multiplier assembly. In a recharge mode, a valve of the charging valve assembly is in an open position, and the fluid is received in a second cylinder of the flow multiplier assembly, causing first and second pistons of the flow multiplier assembly to move in a first direction. In a purge mode, the valve is in the seated position, and the fluid is received in a first cylinder of the flow multiplier assembly, causing the first and second pistons to move in a second direction, and discharging an outlet flow through an outlet of the flow multiplier assembly. The second cylinder may have a bore cross sectional area that is greater than a bore cross sectional area of the first cylinder. Apparatuses disclosed herein may be implemented in a circumferential sampling tool.
