Shallow pool type nuclear energy low-temperature heating reactor device and running method thereof

Abstract

The invention discloses a shallow pool type nuclear energy low-temperature heating reactor device and a running method thereof, relates to the technical field of nuclear energy low-temperature heatingreactors and aims to solve the technical problem that the safety and the economy of a conventional swimming pool type low-temperature heating reactor are not ideal and required to be improved. The shallow pool type nuclear energy low-temperature heating reactor device comprises an in-pool main circulating water pump and an in-pool main heat exchanger arranged in a shallow pool; the in-pool main circulating water pump is arranged at the head end of a primary circuit, an inlet of the in-pool main circulating water pump is communicated with the shallow pool, and an outlet is connected with an inlet of a reactor core; an outlet of the reactor core is connected with a primary circuit water inlet in the lower end of the in-pool main heat exchanger. The shallow pool type nuclear energy low-temperature heating reactor device and the running method thereof disclosed by the invention have the benefits that as the full immersion type in-pool main circulating water pump and the in-pool main heatexchanger are adopted, the possibility of large loss of a heat carrying agent in the reactor can be naturally eliminated; as the in-pool main circulating water pump is arranged at the head end of theprimary circuit of the reactor, the pressure in each of the reactor core and the primary circuit, the reactor core outlet temperature, the thermal safety margin of the shallow pool low-temperature heating reactor and the heat transfer capacity of each of the reactor core and the main heat exchanger can be improved under the action of pressurization of the in-pool main circulating water pump.

Description

technical field [0001] The invention relates to the technical field of nuclear energy low temperature heating reactor, in particular to a shallow pool type nuclear energy low temperature heating reactor device and an operating method thereof. Background technique [0002] With the continuous improvement of my country's urbanization and people's living standards, urban central heating is developing rapidly. The heating area in the north has developed to 17 provinces, municipalities and autonomous regions, and the heating population has exceeded 700 million. At present, most of the central heating in cities across the country still relies on combined heat and power generation and regional boiler rooms. The fuel used is mainly directly burned coal. The annual heating consumption of coal has exceeded 500 million tons, and the combustion products are directly distributed at low altitude in densely populated areas. Emissions are one of the main reasons for the frequent inter-provi...
