Title:
CONSTRUCTION METHOD FOR STEAM GENERATOR OF TWO-LOOP TYPE PRESSURIZED LIGHT WATER REACTOR AND REVERSE DISPLACEMENT SYSTEM THEREFOR FOR CONSTRUCTION OF REACTOR PIPE
Document Type and Number:
WIPO Patent Application WO/2017/099457
Kind Code:
A1
Abstract:
The present invention relates to a construction method for a steam generator of a two-loop type pressurized light water reactor and a reverse displacement system therefor for construction of a reactor pipe, in which the amount of welding shrinkage can be controlled when a high-temperature pipe is connected between the reactor and the steam generator, so as to remove an influence of a residual load on a steam generator support, thereby effectively preventing a heat-transfer pipe from being damaged by frictional resistance and vibration caused by thermal expansion when a reactor facility is operated. The construction method of the present invention comprises: a step for mounting a plurality of hydraulic devices on a forged anchor plate and a bearing plate; a step for mounting a sliding base on the hydraulic devices; a step for setting and aligning a steam generator on the sliding base; a step for connecting pipes of the steam generator through welding; and a correction step for identifying the displacement of the sliding base through displacement sensors after the mounting of the sliding base and then reversely displacing the sliding base by the displacement thereof by means of the hydraulic devices.
