Reactor-core isolation cooling system with dedicated generator

A nuclear reactor complex comprising:

• a dual-phase nuclear reactor, said nuclear reactor including a reactor pressure vessel, a reactor core within said reactor pressure vessel, and recirculation means for circulating fluid within said reactor pressure vessel and through said core to transfer heat generated by said core;
• a main turbine for converting phase-conversion energy stored by vapor into mechanical energy for driving a generator, said turbine being coupled to said reactor via a vapor line during normal operation;
• a main generator for converting said mechanical energy into electricity, said main generator being mechanically coupled to said main turbine via a drive shaft;
• a fluid reservoir external to said reactor;
• a reactor core isolation cooling system with several components at least some of which require electrical power, said components including
• an auxiliary pump for pumping fluid from said reservoir into said reactor pressure vessel,
• an auxiliary turbine for driving said pump, said auxiliary turbine being couplable to said reactor pressure vessel during blackout conditions for receiving vapor therefrom,
• control means for regulating the rotation rate of said auxiliary turbine so as to regulate the rate at which said auxiliary pump pumps fluid into said reactor pressure vessel,
• cooling means for cooling said control means, said cooling means having a input for receiving electrical power, and
• an auxiliary generator coupled to said auxiliary turbine for providing at least a portion of the electrical power required by said components during a blackout condition.
