STEAM GENERATOR OF A INTEGRAL REACTOR HAVING HEAT TRANSFER TUBE COMPOSED WITH HELICAL TUBES AND STRAIGHT TUBES

摘要

The present invention is a one-piece steam reactor is equipped with a heat pipe that is mixed with a straight pipe and a spiral pipe is arranged in a straight pipe heat pipe is mixed to improve the space utilization efficiency in order to minimize the space loss generated in the steam generator for the integral reactor equipped with a spiral heat pipe It is about a generator. An integrated reactor steam generator having a heat pipe mixed with a straight tube and a spiral tube according to an embodiment of the present invention is disposed inside the reactor vessel, at least one body having a tubular shape; A heat transfer tube having a plurality of spiral tube shapes disposed in an annular structure inside the main body; An inner tube forming a flow path independent of a region in which the spiral tube-shaped heat transfer tube is disposed; A heat pipe having a plurality of straight pipes disposed at an inner position of the inner pipe; A pair of headers to which end portions of the spiral tube type heat transfer tube and the straight tube type heat transfer tube are connected; And a cap coupled to both ends of the main body and having a plurality of holes formed therein so that the primary system flows into the main body and the inner tube. By the above configuration, the present invention can make full use of the non-utilized space in which the heat exchange (heat transfer) is not performed in the integrated reactor, and increase the effective heat transfer area (area) to improve the efficiency of the nuclear reactor, This can be done more efficiently, reducing the size of the reactor.
