摘要： PROBLEM TO BE SOLVED: To achieve a continuous process for continuously synthesizing an oligomer by sufficiently progressing the concentration and condensation of a raw material in the oligomer synthesis using a hydroxy carboxylic acid as the raw material.
SOLUTION: Lactic acid is continuously transported from a lactic acid feeder 1 to a lactic acid-concentrating device 2, and water is evaporated by heating. The concentrated lactic acid is continuously transported to a concentrated lactic acid-condensing device 3, and the condensation reaction is progressed by heating/reduction of pressure. The oligomer is continuously discharged from the concentrated lactic acid-condensing device 3, and transported to to a depolymerization device 4. Steam is condensed and removed by condensation devices 7, 8. The lactic acid-concentrating device 2 and the lactic acid-condensing device 3 are horizontal type polymerizers, and the reaction products flow in the horizontal direction from the inlet side to the outlet side while keeping piston flow properties by the difference of heads. The vapor lactide generated at the depolymerization device 4 is recovered by a lactide-recovering device 6.

摘要： PROBLEM TO BE SOLVED: To improve the efficiency of decomposing organic matter without increasing the size of the apparatus. SOLUTION: Raw water is irradiated with an ultraviolet rays emitted from an ultraviolet source 3 (which, like an Ar-F excimer source, emits at least an ultraviolet rays of a wavelength in the range of 190-210 nm) in an ultraviolet irradiation tank 2. Benzene-ring-containing organic matter (such as aromatic polymers) contained in the raw water can be decomposed. When a pump 12 runs, the water is sent from the tank 2 to an ion exchange resin tower 6. The ion exchange resin in the tower 6 adsorptively removes ions from the water. The effluent water is further sent to a filter 7 to be stripped of a particulate component. The ultraviolet rays having the above wavelength can avoid being absorbed by water and can directly decompose the benzene-ring-containing organic matter. Further, the amount of H2 O2 formed can be reduced, and the deterioration of the ion exchange resin can therefore be suppressed.

摘要： PROBLEM TO BE SOLVED: To reduce the consumption of raw material gas and to reduce running cost in the treatment of waste liquid by circulating air after aeration to mix the same with the raw material gas. SOLUTION: Raw material gas is supplied to an ozone generator 2 from an oxygen cylinder 1 and a part of oxygen is changed to ozone in the ozone generator 2 by the silent discharge of the raw material gas. The formed ozone gas is injected in the waste liquid supplied to an aeration tank 3 through an air diffusing pipe 4 to perform aeration. Herein, an injector 7 is used in the suction and mixing of air after aeration. Negative pressure is generated in a circulating line 5 corresponding to the flow velocity of the raw material gas and a part of air after aeration is guided to the injector 7 to be mixed with the raw material gas. The mixing ratio of the raw material gas and the circulated air is adjusted by a damper 6. Excessive air is discharged from a vent piping 8. By this constitution, the injection amt. of ozone in the waste liquid is made constant and, when operation is performed so that the mixing ratio of the raw material gas and circulated air becomes 1:1, the raw material gas can be conserved to 1/2.

摘要： PROBLEM TO BE SOLVED: To extend life of a melting tank used for a melt processing device of radioactive waste. SOLUTION: A melting tank 4 having an openable lid 15 is surrounded by a ring-shape coil 1. Magnetic cores 7A and 7B locate above the central axis of the melt tank 4. The magnetic core 7A is placed inside the lid 15 and the magnetic core 7B is placed outside the melting tank 4 and the bottom end of the tank 4. Electric conductive solid heating medium 14 is charged in the melting tank 4 and incombustible solid waste 17 of metal waste such as pipes and components generated from a reactor power station is thrown in the melting tank 4. Owing to induction magnetic field generated by current to the coil 1, the incombustible solid waste 17 is melted. By placing the magnetic core 7A and 7B, the magnetic field distribution in the melting tank 4 becomes low in the side wall part of the tank 4 and high in the position apart from the side wall of the tank 4 to the center. So the temperature in the side wall part in the tank lowers and the life of the melting tank 4 is prolonged.

摘要： PURPOSE: To restrain the deterioration of a solidified body caused by Ettringite generation and to prevent anion containing a radioactive nuclide from exuding to the outside of the solidified body by adding salt containing a large anion to a solidifying material. CONSTITUTION: A radioactive waste liquid and a swelling inhibitor are respectively supplied to a waste liquid supply tank 6 from a waste liquid supply tank 8 and a swelling inhibiting material supply tank 9, agitated by an agitator 11 and then supplied to a kneading device 1. After an adsorbent is added to a solidifying material from an anion adsorbent supply tank 12, and the solidifying material is supplied from a supply tank 4 to the kneading device 1. After the material is kneaded into a paste by the keading device 1, it is poured into a filling container 3. Large anions such as an iodic acid ion, a perrhenium acid ion, a periodic acid ion and so on are added in the salt form to the solidifying material. The anions are linked with calcium and aluminum. Thus, the generation of a Ettringite compound having large expansibility can be restrained and the deterioration of a solidified body can be restrained.

摘要： PURPOSE:To highly accurately detect leakage gas without sampling by enclosing helium gas labeled by a small quantity of labeled gas in a sealing vessel and optically detecting the gas leaked into a housing tube from the sealing vessel by a sensor attached to the housing tube. CONSTITUTION:For instance, a sail quantity of carbon monoxide is enclosed in a sealing vessel 2 enclosing used fuel 1 as labeled gas together with helium gas of good heat conduction. In the case where a hole is opened in the sealing vessel 2 by corrosion or the like, helium gas containing carbon monoxide is leaked in the inside of a housing tube 3. Since carbon monoxide absorbs an infrared ray in the neighborhood of wavelength of 5.5mum and an absorption coefficient is very large, the infrared ray not exceeding the wavelength of 5.5mum is transmitted from a detection part 8 to a sensor 6. If a quantity of attenuation is measured in the inside of the housing tube 3, leakage can be detected in high accuracy. Thereby radiation leakage can be monitored in high accuracy without performing troublesome sampling.
