Abstract

The invention provides a structure for suppressing flow vibration of an instrumentation guide tube, comprising a tube configured to be in a hollow upper core support column between an upper core supporting plate and an upper core plate in a reactor vessel; and a front end nozzle configured to be at a lower end of the upper core support column, wherein the lower end part of the instrumentation guide tube is from up to down successively goes into the tube, the front end nozzle and an opening part on the upper core plate to be inserted into the core, wherein the at least a lower part of the tube side is provided with a lower part hole; the instrumentation guide tube is pressed on an inner circle surface by the pressure difference between the inner side of the lower part hole and the cooling materials on the outer side.

Description

[0001] This application is a divisional application, the application number of its parent application is: 200880005834.4, the application date: 2008.02.22, the name of the invention: the flow vibration suppression structure of the measuring instrument conduit. technical field [0002] The present invention relates to a flow vibration suppressing structure of a gauge conduit inserted into a core. Background technique [0003] When a neutron detector is installed in the core of a pressurized water reactor (PWR), the detector is guided into the core through a gauge guide inserted into the core. In addition, as a method of inserting the gauge conduit into the core, the bottom insertion method of inserting the gauge conduit from the bottom to the top of the reactor vessel has been used previously, but in the current technology, the method of inserting the gauge conduit from the top of the reactor vessel to the top is being considered. An upper insertion method that inserts the ga...
