Abstract
The utility model belongs to piping system and piping layout of a nuclear reactor system, and particularly relates to a reactor coolant expansion or shrinkage compensation pipeline in the nuclear reactor system. The reactor coolant expansion or shrinkage compensation pipeline in the nuclear reactor system comprises a reactor container with a reactor core, a filler neck for connection of the pipelines, a voltage stabilizer and a hot water pipe, wherein the filler neck of the voltage stabilizer is arranged at the lowest point of the voltage stabilizer, the hot water pipe is arranged between the reactor container and the voltage stabilizer, the top of the hot water pipe is located at a first height and higher than the reactor container, and the bottom of the hot water pipe is located at a second height and is higher than the bottom of the reactor pressure container. The reactor coolant expansion or shrinkage compensation pipeline has the advantages of being directly used for connecting the reactor container and the voltage stabilize and achieving a very good volume compensation effect; and a corresponding connector can be arranged on the hot water pipe according to the need.
Description
Technical field
The invention belongs to piping and the piping arrangement of nuclear reactor system, be specifically related to reactor coolant expansion or shrinkage-compensating pipeline in a kind of nuclear reactor system.
Background technology
Operation both at home and abroad at present or the nuclear power apparatus of building again adopt decentralized to arrange mostly, the fluctuation pipe is a kind of piping that connects trunk line and voltage stabilizer, because integrated reactor does not have trunk line, can't be as the decentralized nuclear power apparatus hot arc by being connected to reactor coolant loop and the fluctuation pipe between voltage stabilizer realize cubage compensation.
Need to propose fluctuation pipe and method for arranging thereof that a kind of novel characteristics that are applicable to integral reactor and advanced nuclear power plant require for this reason.
Summary of the invention
The purpose of this invention is to provide a kind of pipeline for the expansion of nuclear reactor system reactor coolant or shrinkage-compensating, between the reactor vessel of voltage stabilizer and reactor core, the reactor coolant medium flows between two back and forth at this, thus realization response reactor coolant media expansion or shrink the cubage compensation that produces.
The present invention realizes like this, in a kind of nuclear reactor system, reactor coolant expands or the shrinkage-compensating pipeline, and it comprises a reactor vessel with reactor core, is used for the pressure inlet of connecting tube, voltage stabilizer, be provided with the voltage stabilizer pressure inlet in its minimum point, hot-water line is between above-mentioned reactor vessel and voltage stabilizer, the top of hot-water line is on the first height, higher than reactor vessel, the bottom of hot-water line is on the second height, higher than the bottom of reactor pressure vessel.
Described hot-water line constantly to downward-extension, arrives a position of reactor pressure vessel from voltage stabilizer, and the middle part of this hot-water line is provided with one and carries out the stub (tube) of interface with other system.
Described hot-water line is provided with some bendings and continuous tilt.
Advantage of the present invention is that it is directly used in coupled reaction heap container and voltage stabilizer, arrives good cubage compensation effect; Simultaneously can as required, corresponding interface be set on hot-water line.
