Reactor internal for power expansion of pool type low temperature heating reactor

Abstract

The invention belongs to the technical field of pool type low temperature heating reactors, and particularly relates to a reactor internal for power expansion of a pool type low temperature heating reactor. The reactor internal is disposed in a reactor pool and includes a reactor core base fixed at the bottom of the pool, a lower hanging basket disposed above the reactor core base, an intermediatehanging basket detachably and replaceably disposed above the lower hanging basket and an upper hanging basket detachably and replaceably disposed above the intermediate hanging basket. The upper hanging basket is used for arranging a driving line for controlling a rod driving mechanism, the intermediate hanging basket is used for arranging a control rod guide barrel, and the lower hanging basketis used for arranging the reactor core. The reactor core can change power by adjusting the number of internal fuel assemblies and simulation assemblies, to meet different power requirements. The reactor internal further includes a plurality of loop systems communicated with the reactor core and a blind plate for blocking the loop system. The reactor internal can expand the power of a reactor according to urban heat supply demand and is simple in structure, redundant loop transformation is not required, the cycle of the heating reactor into use is shortened, and the economy is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of a swimming pool type low temperature heating reactor, and in particular relates to a reactor internal component for power expansion of a swimming pool type low temperature heating reactor. Background technique [0002] Nuclear energy heat supply is a way to centralize heat supply to surrounding cities with the energy generated by nuclear fission as the heat source. Compared with traditional heat sources, it can significantly reduce pollution emissions, and the heat supply is safe and reliable. It will effectively improve my country's energy structure and alleviate the increasingly serious The tense energy supply situation in China has positive significance for protecting the environment, protecting people's health, and alleviating the pressure on coal burning. [0003] There are three main types of cryogenic heating reactors designed and constructed at present: shell type pressurized type, pool type pressu...

Problems solved by technology

The design power of the first two types of reactors is generally larger, and the thermal power reaches 200-600MW (megawatts). According to the calculation of the urban heating network load, a 200MW heating reactor can satisfy 100,000 households with a 100m2 2 The three-bedroom, equivalent to 10 million m 2 , which can satisfy most large and medium-sized cities. Many small and medium-sized cities and industrial areas in China are in urgent need of low-temperature heat sources. The economics and market expansion of nuclear heating
