摘要： PURPOSE: To drastically improve the solvent recovery rate and to save the solvent consumption by arranging a capacitor for condensing and liquefying an evaporated solvent contained in exhaust gas in the case of an exhaust dry process in a discharge line and recovering the solvent which is condensed and liquefied by a condenser with a recovery means. CONSTITUTION: The condenser 11 is disposed between a fan 3 and a filter 2 and the exit side of the capacitor 11 is connected to a moisture separator 12. The condenser 11 is arranged at a position to be the discharge line of an opening circuit in case a three-way valve 7 is changed-over to a discharge side. Besides, the condenser 11 is a low temp. condenser which is cooled to 0 deg.C or below by a freezer like a secondary condenser 5 and is set to be operated in the case where the cross valve 7 is changed-over to the discharge side. The condenser 11 arranged between the filter 2 and the fan 3 condenses and liquefies the solvent which is discharged from a washing drum together with evaporated air, the solvent is stored in a new liquid tank 13 through the moisture separator 12 and, the quantity of the solvent to be discharged to the air together with evaporated air is reduced.

摘要： PROBLEM TO BE SOLVED: To shorten a construction process for the diaphragm floor of a reactor containment vessel. SOLUTION: Components for the diaphragm floor of a reactor containment vessel are assembled around a built-in beam 34 so as to include a diaphragm liner 85, they are changed into a module in the same arrangement as a set state, and the module 51 is carried into the reactor containment vessel by using a large lifting machine so as to be set on cradles 44, 45 which are installed on both a pedestal 11 at a reacor pressure vessel and a reactor-containment- vessel outer wall 13. In addition, when reinforced concrete is executed, a concrete placing operation is performed so as to be divided into a plurality of operations in the thickness direction, and a first concrete placing load is supported by the built-in beam 34 while the diaphragm liner 85 is connected to the built-in beam. After the first concrete has been solidified so as to generate its strength, a second concrete placing operation and subsequent placing operations are repeated, and placing loads in the operations are supported surely by the previously solidified concrete and by the built-in beam 34.

摘要： PURPOSE: To take out distillation residues and to reduce a residual amount by newly installing a different container for receiving the distillation residues containing moisture. CONSTITUTION: The distiller 13 of a second stage is attached to a residual exit pipe side from the distiller 7 of a first stage. For the distiller 13, in order to easily take out solid residues inside, for instance, a container 12 is put in the distiller 13 and a structure capable of taking out the container 12 is attained. Residual liquid waste condensed to a certain degree in the distiller 7 is made to flow in from an entrance pipe 15 to the distiller 13. Then, by putting in heating steam from a steam entrance pipe 16 and discharging it from a steam exit pipe 17, the injected residual liquid waste is heated and vaporized and steam is discharged from the steam exit pipe 14, made to enter a capacitor 8 and liquefied. The residual waste made to flow in is solidified and made into powder in the container 12. Thereafter, by detaching a distiller bottom plate 18, the container 12 containing the solidified residue is taken out.

摘要： PROBLEM TO BE SOLVED: To reduce the construction process of a nuclear power plant that accompanies the installation of a reactor pressure vessel base by using the module which is composed of a cylindrical reactor pressure vessel(RPV) base and components arranged and provided in the cylindrical inner space united with the reactor pressure vessel base. SOLUTION: The inside and outside of a pedestal 1 of an RPV 4 are made of a cylindrical steel plate that also plays a role of the form for placing concrete to fully withstand vibration by supporting the load of the RPV 4, and a high-strength concrete is filled into the space between them. By suspending a module at an installation position for setting, the pedestal 1 of the RPV 4 can be installed all at once and succeeding constructions of a diaphragm and a reactor storage container can be speeded up. Also, with the mounting surface of the RPV 4 of the pedestal 1, a deformation dimension due to a distortion when a module is manufactured by welding is adjusted to a regular height by cutting and machining the upper surface of a trestle 13, so that a height adjustment when assembling the RPV 4 to the pedestal 1 of the RPV 4 can be drastically reduced and hence the construction process of a nuclear power plant can be reduced.
