Embodiment Construction
[0025] The technical solution of the present invention is to adopt a flat core, reduce the ratio of reactor core height to diameter, expand the volume and surface area of the reactor core fuel solution, facilitate the escape of radiation decomposition gas, and reduce the cavitation coefficient and The surface release rate of the fuel solution for radiolysis gases (hydrogen and oxygen) prevents sharp fluctuations in reactor power; controls the specific power of the core, and adds ruthenium metal ions to the core fuel solution to catalyze H 2 o 2 Decompose, avoid UO 4 Precipitation occurs, and HNO is added after the hydrogen-oxygen recombiner in the reactor gas circuit 3 Nitrogen from radiolysis is directly converted to HNO 3 device and automatic continuous HNO supplementation 3 system that makes the reactor fuel solution HNO 3 Stable concentration, avoid HNO 3 A drop in concentration causes UO 2 +2 Hydrolysis and precipitation ensure the uniform stability of the fuel s...
