Abstract

FIELD: nuclear heat and power generating stations. SUBSTANCE: plant has housing 1 with auxiliary pipe connections 2-5, fuel element supports 6, liquid working medium circulating and sprinkling devices. Housing 1 has light-transparent walls 8 and incorporates lamps 9; waste liquid discharge pipe connection 4 communicates with microfilter 10 of chlorella compartment and for chlorella biomass, with disintegrator 11; for excess biomass of chlorella, microfilter 10 communicates with pyrolysis chamber 14 that has transport drive element 15, with upper drying part 16, and with lower pyrolysis drive element 15, with upper drying part 16, and with lower pyrolysis circuit 17; the latter has grate 18 of furnace 19 under it which communicates with fuel source 20 (for example, biomethane source) and with oxidizer source 21 (such as oxygen source); pyrolysis chamber 14 communicates with solid radioactive waste container 22 and for gas, with sprayers of housing 1. EFFECT: reduced surface radioactivity before transportation for recovery.

Claims

The invention relates to techniques for extracting fuel rods to reduce surface radioactivity before transportation for processing and can be used at nuclear thermal and power plants. The inventive installation of the exposure of the fuel rods contains a housing with technological pipes risers stacking fuel rods 7 devices for circulation and irrigation with a liquid working medium. The housing is made with translucent walls, equipped with lamps, and the drainage pipe is connected to the chlorella separation microfilter, and the chlorella biomass is disintegrated, and the chlorella excess biomass is connected to the pyrolysis chamber, including the drive unit, with the top drying part and lower pyrolysis branches, and under the latter there is a grate of a furnace connected to a source of fuel, for example, biomethane and a source of oxidizing agent, for example, oxygen, while the pyrolysis chamber TPO and the container, and a gas gun mounting the fuel elements shutter housing.
