摘要： The emergency core cooling structure according to the present invention is provided with a water storage container (32) which holds therein emergency cooling water to be supplied to a core region (2) in a nuclear reactor in case of an emergency, for example, when the primary cooling water flows out from a reactor vessel (1), so as to maintain the temperature of the emergency cooling water in the upper portion of the water storage container (32) in a level higher than the level of that of the emergency cooling water in the lower portion thereof, the lower portion of the water storage container, which is filled with the low-temperature cooling water, being communicated at all times with the core of the nuclear reactor by a means (4, 35; 22, 41; 19, 35, 41) which has substantially no movable member. When the primary cooling water flows out, so that the pressure in a reactor vessel (1) decreases, the emergency cooling water in the high-temperature region is boiled to expand to cause the low-temperature emergency cooling water in the lower portion of the water storage container (32) to be raised, the resultant low-temperature emergency cooling water being supplied to the core region (2).

摘要： PURPOSE: To process by means of NC machine tools and lower the cot by making the inside of a shroud head with which a stand pipe is to be welded have a flat structure. CONSTITUTION: A shroud head 1 of a BWR is made to have a flat structure. With that structure, a connecting work of a stand pipe to connect a steam separator 2 with a shroud head 1 and a machining work of a through hole of the shroud head become easy. Consequently, processing by NC machine tools, etc., is made possible. Also, edge finishing of the through hole can be machined and thus the cost can be lowered. Furthermore, as for the power of the steam separator 2, since the length of all stand pipes 3 can be made the same, the pressure losses due to the flows of water-steam two-phase currents become equal, so that all of the stand pipes 3 have a uniform power.

摘要： PURPOSE:To meet the fluctuation of demanding side by a method wherein the excessive amount of heat of an incinerator is reserved in an accumulator to supply it to a heat load by discharging it in accordance with necessity. CONSTITUTION:A waste heat boiler 3 is heated by the waste heat 2 of an incinerator 1 to generate steam while the steam is supplied to a steam turbine load 10, thermal loads 17, 18, a heat accumulator 6 and a supplying refuge heater 7. When the load of the thermal loads 17, 18 and the steam turbine 10 is absorbed and there still is excessive amount of heat, the steam is poured into an accumulator 6 to store heat. When the load of the thermal loads 17, 18 and the steam turbine 10 can not be absorbed even under a condition that a reducing valve 8a, a fine regulating reducing valve 8c and a valve 8d are opened and the shortage of the amount of heat is generated, the heat, accumulated in the accumulator 6, is supplied to the thermal loads 17, 18 by opening the reducing valve 8b of a pipeline 6p to suffice the shortage of heat. According to this method, the utilizing efficiency of recovery heat is improved.

摘要： PURPOSE:To increase a generating amount per a unit area by high-efficiently collecting generating units utilizing natural energy, e.g. solar light, light collection heat collection postheat generation, a wind power, a wave power, tidal power, and installing the generating unit installed off-shore (in the vicinity of coastal line). CONSTITUTION:A power generating system utilizing solar light is constituted such that solar light 1 is collected to a heat pipe 3 by means of parabola reflection mirror 2, heat is transmitted to a high temperature tank 5, and a liquid metal 4 in the tank 5 is heated to approximate 600 deg.C. Since an electrode 8 of a thermoelectric conversion element 7 at the lower part of the tank 5 is immersed in holding water 10 (cooled by sea water to a temperature of approximate 20 deg.C) in a hydrogen manufacturing electrolytic cell 9, a high temperature difference is exerted on the element 7 to generate a power. In a wind power generating system, by receiving wind 12, the reflection mirror 2 itself is rotated, and the rotation force thereof is transmitted to a generator 14 through a gear 13. In a wave power generating system, a power is generated by vertical movement of. a floating body 9 on which the two solar light utilizing and the wind power generating systems are placed. In a tidal power generating system, an impeller 22 is rotated by means of a tidal current 21 to generate a power by a generator 23. The AC power thereof is regulated in a regulating device 35.
