Abstract

The invention discloses an integral low-temperature nuclear heat reactor with the circuit equipment adopting integral arrangement and belonging to the low- and medium-parameter pressurized-water reactor, wherein, a reactor core adopts the mature nuclear power plant fuel component and control rod component; a main heat exchanger is of integral coil type; a voltage stabilizer is a built-in nitrogen partial pressure control voltage stabilizer; coolant circulation is completed by a built-in jet apparatus and the equipment of an external drive circuit; the drive circuit and the equipment and a main circuit auxiliary system are arranged at the circumference of a reactor pressure vessel; a containment vessel consists of a reactor body containment vessel and a reactor top containment vessel; the reactor body containment vessel which is a structure combined by a reactor vault of reinforced concrete structure and a casing of steel structure is connected with a sealed refueling water storage pool through a pipe and a valve. The thermal power of the reactor can be selected between 50MW and 500MW at will and the outlet temperature of the reactor can be selected between 100 DEG C to 200 DEG C according to application, requirement and power.

Description

technical field [0001] The invention belongs to a nuclear reactor, in particular to a low-temperature nuclear heating reactor. Background technique [0002] When nuclear energy is used as a clean energy source for urban district heating, due to nuclear safety requirements, reactors must be built near densely populated cities. In recent decades, countries around the world have conducted a lot of exploration and applied research on nuclear energy district heating. Although there are many types of low-temperature heating nuclear reactor designs at home and abroad, they have not been widely accepted due to their economy and safety. application and development. Therefore, seeking a reactor type with high safety and reliability, simple operation and low construction and operation costs is the key to the widespread application of nuclear energy heating. [0003] At present, nuclear energy is mainly used as a heat source for urban district heating, seawater desalination and indust...
