摘要： A sludge lance for a tube and shell steam generator that has a central divider plate that extends substantially the length of a central tube lane substantially bisecting a hand hole through which the tube lane can be accessed. The sludge lance has a nozzle with a spring biased, reciprocally movable plunger that extends against the divider plate and is locked in position by a stream of high pressure cleaning fluid that traverses the nozzle and exits through jets to clean sludge from between the tubes. An alignment tool with a swing arm indexes the jets to assure they are properly aligned with the tube rows and spaced from the divider plate.

摘要： A miniature sludge lance for a steam generator in a pressurized water nuclear reactor is provided. The sludge lance is structured to enter the steam generator via an inspection opening and has a body sufficiently thin to fit between adjacent tubes. The sludge lance rail has at least two types of nozzle assemblies that may be attached thereto. One nozzle assembly rotates and another nozzle assembly translates in a vertical direction. A drive assembly, a mounting assembly, an oscillation assembly, and flow straighteners are also provided.

摘要： Provided area cleaning apparatus and an associated method of using the disclosed apparatus wherein the apparatus utilizes one or more nozzles configured to provide a coherent stream of one or more cleaning fluids for removing accumulated fine particulate matter, sludge, from surfaces. The nozzles may be sized, arranged and configured to provide coherent streams that maintain the initial stream diameter for a substantial portion of the maximum dimension of the space being cleaned. The apparatus and method are expected to be particularly useful in the cleaning of heat exchangers incorporating a plurality of substantially vertical and narrowly spaced tubes by directing cleansing streams along a plurality of intertube spaces.

摘要： An apparatus for use with a search device and a foreign object extrication device in a steam generator includes a router having two conduits for routing the search and extrication devices, and a positioning mechanism for positioning the conduits. The extrication device may include a cable having a pushing mechanism for pushing a foreign object within the steam generator and a hook mechanism for pulling the foreign object. Alternatively, the extrication device may include a loop mechanism for pulling. The extrication device may include a cable having a slotted end for pushing. Alternatively, the cable may have an anvil for pushing. The router may include a guide tube interconnected with the first conduit for guiding the search device from the tube lane into a selected one of the tube rows of the steam generator and another guide tube interconnected with the second conduit for guiding the extrication device from the tube lane into the selected tube row. Alternatively, the two guide tubes may guide the search and extrication devices into the annulus. The router may also include an attachment for removably attaching the guide tubes to the conduits. Alternatively, the apparatus may be adapted for use with a sludge lancing system in a steam generator having a first half and a second half separated by a tube lane. The apparatus may include a router having four conduits for routing the search device and the extrication device from the tube lane into the two halves. Alternatively, the router may have four conduits for routing the search and extrication devices into two halves of the annulus of the steam generator. Alternatively, the router may have two conduits for positioning by the positioning device, two guide mechanisms for guiding the search and extrication devices, and a connection mechanism for removably connecting the two conduits to the two guide mechanisms. The connection mechanism may include two Y-conduits for two conduits and four guide tubes.

摘要： An apparatus and process for making the fibrous structure, having three four, and more regions. The process is similar to known papermaking techniques, but comprises the additional steps of applying a differential pressure to selected regions of the fibrous structure which are not coincident with the regions of the fibrous structure defined by the apparatus in prior steps of the papermaking process. The selective application of noncoincident differential pressure to selected regions of the fibrous structure may result in densification or dedensification of such regions.

摘要： An automated sludge lance and method is described for cleaning sludge from tubes in a steam generator. The lance guide and waterlance are moved inside the steam generator to direct a fluid between the tubes to effectively clean sludge from the tubes. The remote control system is mounted outside the steam generator where it is readily serviceable. The automated sludge lance and method can be used in the no-tube-lane, in the annular chamber, or in combination.
