摘要： A radioactive waste (zeolite to which Cs-137 was adsorbed) in a waste tank and a glass raw material (soda lime glass) in a glass raw material tank are supplied into a solidifying vessel. Graphite in a graphite tank is also supplied into the solidifying vessel. The solidifying vessel is filled with a mixture of the radioactive waste, glass raw material, and graphite and is then disposed in an adiabatic vessel. The radioactive waste and glass raw material in the adiabatic vessel are heated by thermal energy generated due to radiation emitted from Cs-137. The heat is transferred to the peripheral portion of the solidifying vessel through the graphite, raising the temperature of the peripheral portion. The glass raw material is melted and enters clearances among the radioactive waste, producing a vitrified radioactive waste. This radioactive waste solidification method can shorten a time taken to produce a vitrified radioactive waste.
摘要翻译： 在玻璃原料槽中的废液箱中的放射性废物（吸附有Cs-137的沸石）和玻璃原料（钠钙玻璃）供给到凝固容器中。 石墨罐中的石墨也被供应到凝固容器中。 固化容器中填充有放射性废料，玻璃原料和石墨的混合物，然后将其置于绝热容器中。 绝热容器中的放射性废物和玻璃原料由于由Cs-137发射的辐射而产生的热能被加热。 热量通过石墨转移到固化容器的周边部分，从而提高周边部分的温度。 玻璃原料熔化并在放射性废物中进入间隙，产生玻璃化的放射性废物。 这种放射性废物固化方法可以缩短产生玻璃化放射性废物所需的时间。

摘要： Higher-order vibration is controlled in an event that an impact load such as an aircraft impact is applied to a nuclear plant.
A higher-order vibration control device 1 is installed in a nuclear plant having a reactor containment vessel and a nuclear reactor building 3. The higher-order vibration control device 1 includes an impactor 1a, a housing 1b which receives the reaction force of the impactor 1a, and a locking mechanism 2. The impactor 1a is installed on a floor 31 of the nuclear plant so as to roll in a horizontal direction with respect to the floor 31. The housing 1b encloses the impactor 1a and guides rolling of the impactor 1a. The locking mechanism 2 restrains rolling of the impactor 1a. In the event that a flying object may possibly impact the nuclear plant, the locking of the locking mechanism 2 is released.-

摘要： A gas supply apparatus of the present invention includes: an operating valve that is placed in the middle of a piping for letting at least gas in a plant flow and that operates a valve main body by the gas flowing in the piping; a first electromagnetic valve 2A that is placed in the middle of the piping and that opens or closes a flow of the gas to the operating valve; and a gas supply source that supplies the first electromagnetic valve 2A with the gas. A gas discharge line of the first electromagnetic valve has a switching valve 3 placed therein and has a second electromagnetic valve 2C placed between the switching valve 3 and the gas supply source. The switching valve 3 switches between a gas discharge from the first electromagnetic valve 2A and a gas supply to the first electromagnetic valve 2A. When a power source is lost, the switching valve 3 is switched to connection to the gas supply source so as to supply the first electromagnetic valve 2A with the gas. At the time of a normal operation, the second electromagnetic valve 2C opens a gas discharge line side and closes a switching valve side, and when the power source is lost, the second electromagnetic valve 2C opens the switching valve side and closes the gas discharge line side. In this way, even when the power source is lost, an operating valve such as an air-operated valve can not only be operated remotely but also be operated safely by a remote operator.
