    摘要: In an indirect cycle nuclear reactor, a size of the reactor containment vessel is decreased by removing decay heat inside the reactor pressure vessel without using any active component to improve the economic feasibility. A main steam pipe communicating with a heat exchanger of the indirect cycle nuclear reactor is branched in a position upstream of a main steam isolation valve to connect the branched pipe to a heat exchanger in a pressure suppression pool through an isolation valve. A feed water pipe is also branched in a position upstream of an isolation valve to connect the branched pipe to the heat exchanger through the isolation valve. Decay heat is dissipated from the heat exchanger into the pressure suppression pool, and condensed water condensed by heat dissipation is returned to the heat exchanger to cool the inside of the pressure vessel. Heat in the pressure suppression pool is transferred from a condensing type heat exchanger to a heat dissipater outside a containment vessel to be dissipated to the outside of the containment vessel.

    摘要: In a plant equipment comprising apparatus of a plurality of systems and control means for switching the systems and changing capacities of the apparatus, an apparatus of each system bas a rated capacity which is 1/N of a capacity of the whole equipment, and the plant equipment is constituted of (N+1) systems. In conditions of normal operation, all the (N+1) systems are operated at capacities less than the rated capacity through the control means. During normal operation, when one system is inspected, or when an abnormality occurs in one system, this system is stopped by the control means. Capacities of apparatus in N of the systems which are operated are increased to the rated 1/N capacity through the control means, and operation is continued with a structure of 1/N capacity.times.N systems. When the maintenance of apparatus in the stopped system is finished, the stopped system is restarted, so as to operate all of the (N+1) systems at capacities less than the rated capacity again.

    摘要: A sheet supply apparatus supplies a sheet such as an X-ray sheet film from a cassette to a recording device. The sheet supply apparatus has at least a pair of rollers for gripping and feeding a sheet, a feeding mechanism for feeding a sheet from a storage cassette and supplying the sheet along a feed path to the pair of rollers, a tilt correcting mechanism having for correcting the sheet out of a tilted condition with respect to a direction transverse to the feed path, and a position correcting mechanism for displacing the pair of rollers in the direction while the pair of rollers is gripping the sheet, to correct the sheet positionally with respect to the direction. The feeding mechanism has suction devices movable into the feed path for attracting the sheet under vacuum, and the tilt correcting mechanism has at least a pair of stoppers movable into the feed path for engaging a leading end of the sheet to correct the sheet out of the tilted condition. The sheet supply apparatus also has a drive mechanism for displacing the suction devices and the stoppers between the feed path and respective positions outside of the feed path.
