Abstract
A nuclear power plant comprising a control building for receiving therein control instruments which make controls of the nuclear energy plant, a reactor building for receiving a nuclear reactor therein, a turbine building for receiving therein turbines and a generator which are driven by steam supplied from the nuclear reactor, said buildings being arrayed in a straight line, and scattering fragments-checking means disposed on the inner wall of a turbine casing, said means functioning so that when a turbine rotary body breaks and scatters, the scattering fragments may collide against it and have their rescattering directions limited.
Claims17
A nuclear power plant, comprising:
- a nuclear reactor;
- control means for controlling the functions of said nuclear reactor;
- means for generating steam from the heat generated by said nuclear reactor;
- turbine means for being driven by the steam generated by said nuclear reactor;
- and said turbine means comprising a rotor having a mounting disk carrying a plurality of blades and being mounted for rotation about a generally fixed axis, a turbine casing surrounding said rotor and being stationarily mounted, and deflection plate means mounted only on a minor segment of said casing within the trajectory that any broken blade and disk portions would travel by centrifugal force from said rotor to said nuclear reactor for deflecting said broken blade and disk portions traveling by centrifugal force toward said nuclear reactor through an obtuse angle to other trajectories away from said nuclear reactor;
- and as seen in a plane perpendicular to said axis, the surface of said plate means that faces inwardly towards said blades being substantially entirely formed throughout its extent so that tangents thereto form outwardly opening acute angles with respect to corresponding intersecting radii so as to deflect any broken particles traveling along trajectories that would otherwise lead them to said nuclear reactor.
