Abstract: Gamma-ray sensing probes operating under the Cerenkov effect measure the burnup of spent nuclear fuel assemblies. The probes include an optical fiber that reacts to gamma rays coming from the spent nuclear fuel assembly and emit light via the Cerenkov effect. A scatterer surrounds the optical fiber to increase the light emitting efficiency of the optical fiber by the Compton electron scattering. A collimator composed of shielding material surrounds the scatterer. The collimator has a slit groove which is open in one direction for directing the gamma rays from the spent fuel assembly to the scatterer.

Abstract: Provided are a gamma-ray sensing probe using the Cerenkov effect, and a system for identifying the burnup of a spent nuclear fuel assembly using the gamma-ray sensing probes, wherein the system is established using the gamma-ray sensing probe including: an optical fiber reacting to gamma rays coming from the spent nuclear fuel assembly by the Cerenkov effect and emitting light by itself; a scatterer surrounding the optical fiber to increase light emitting efficiency of the optical fiber by the Cerenkov effect; and a collimator configured to surround the scatterer and composed of a shielding material, the collimator having a slit groove which is open in one direction, whereby the burnup of the spent nuclear fuel assembly can be accurately determined.

Abstract: Provided are an apparatus for supplying amine, including: transfer pipe through which amine is transferred; a heat wire which heats the amine that flows through the transfer pipe; a temperature control sensor which controls the temperature in the transfer pipe; and a product recovery valve which recovers product resulting from thermal decomposition of the amine, and a method for supplying amine using the same. The apparatus and method for supplying amine are capable of economically and effectively supplying amine utilizing the thermal decomposition properties of the amine, and may be used to supply amine, for example, to circulating water for power plants.

Abstract: Provided is a physical and chemical cleaning method, including introducing nitrogen gas, liquid nitrogen or dry ice into a cleaning solution containing at least one selected from the group consisting of water, monoethanolamine (ETA), dimethylamine (DMA), NH3, ethylenediaminetetraacetic acid (EDTA), diethylenetriaminepentaacetic acid (DTPA) and N2H2 to remove sludge. The physical and chemical cleaning method is capable of removing sludge, generated or deposited on the substrate surfaces, surfaces of constitutional parts, or gaps in various systems and instruments, more effectively. The physical and chemical cleaning method may be applied to cleaning of steam generators, boilers, heat exchangers, or the like, used in atomic power stations.

Abstract: Provided is a method for recovering high-concentration and high-purity amine from amine-containing waste water generated from nuclear power plants and thermal power plants. The method includes: capturing amine and concentrating waste water using a cation exchange resin; separating amine from the concentrated amine-containing waste water; and carrying out further separation of amine via distillation. The method may be applied to treat amine, which causes an increase in biochemical oxygen demand (BOD) and total nitrogen concentration, drastically at the time of its generation from waste water of nuclear power plants and thermal power plants. In this manner, the method may prevent an increase in load of existing waste water treating plants and avoid a need for modifying the equipment in the existing plants.

Abstract: Advanced treatment method and system of ethanolamine-containing wastewater are disclosed, which perform physicochemical and biological treatment processes. The method regenerates cation exchange resin that captures ethanolamine discharged from a nuclear power plant or a thermal power station, concentrates the ethanolamine-containing wastewater to reduce the volume of the wastewater, and then treats the highly concentrated ethanolamine-containing wastewater through biological decomposition and denitrification processes. The system for treating ethanolamine-containing wastewater performs the physicochemical process (ion-exchange and resin regenerations) where the waster is concentrated, and then applies the biological process to the small amount of wastewater highly concentrated. The physicochemical process is composed of exchanging ions and eluting/concentrating ethanolamine using sodium hydroxide.
