On November 28, CNNC officially released its 'Yanlong' pool-type low-temperature heating reactor, which has been independently developed to provide district heating.
With the advent of the northern heating season, while the heating needs of ordinary people, while heating coal-fired heating north of the haze aggravates the contradiction, to find a new alternative coal-fired clean energy has become imperative.As a safe and clean energy, How to use nuclear energy for district heating has gradually entered the people's vision.
After years of research and development, on November 28, CNNC formally released its 'Yanlong' pool-type low-temperature heating reactor, which is independently developed and can be used to realize district heating in Beijing. According to estimates, a 400MW (1MW = 1000KW) 'Low-temperature heating reactor, heating construction area of up to about 20 million square meters, equivalent to 200,000 three-bedroom.
On the same day, as the first step in the three-step development strategy of swimming pool-based low-temperature heating reactor demonstration demonstration demonstration project commercial promotion, CNNC's heating demonstration project started by China Institute of Atomic Energy-swimming pool light water reactor (49-2 heaps) to achieve safe heating over 168 hours, with the provision of heating for some of the IAEA office building (two nuclear power plant area office building and a 49-2 pile plant, the overall heating area of about 10,000 square meters) , Functional demonstration and practical training capabilities.This fully verified the feasibility and safety of swimming pool heap heating, but also marks the nuclear group made significant progress in the field of nuclear energy heating technology for the follow-up pool type low temperature heating reactor model design R & D provides a strong technical support.It is understood that China Nuclear Group has set up a nuclear energy heating technology research center.
With the success of the "Yanlong" model release and the demonstration of 49-2 Heater Heating demonstration, CNNC will further accelerate the implementation of demonstration projects.
Nuclear Group will be swimming pool-type low-temperature heating reactor model, code identified as 'Yanlong' and 'DHR-400'. The pile developed in Yanzhao earth, used in Yanzhao earth (extending to the northern city), and belongs to the nuclear group The self-developed "Dragon" series of reactor models, so named as' Yan Long 'and' DHR-400 '(District Heating Reactor)' is the district heating reactor, '400' refers to the reactor thermal power 400MW.
'Yanlong' is a safe, economical and environment-friendly heap developed by CNNC for more than 50 years of safe and stable operation of the swimming pool research reactor in northern cities. The principle is to place the reactor core In the depths of an atmospheric pool, the hydrostatic pressure at the outlet of the core is used to increase the water temperature at the outlet of the core to meet the heating requirements, and the heat is transferred to the heating circuit through two stages of exchange, which transfers the heat to millions of households.
As a mature and safe reactor, Yanlong owns notable features of zero melting, zero emission, easy retiring and less investment. Based on the multi-channel safety barrier of the reactor, the pressure is increased High isolation circuit to ensure radioactive isolation from the hot network.Pool type low temperature heating reactor siting flexible, inland coast can be, very suitable for northern inland.Cool-type low temperature heating reactor life of 60 years in the economy , The heat price is far better than the gas, and coal-fired, cogeneration is economically comparable. Reactor decommissioning thoroughly, the site can be achieved green reuse.
