METHOD FOR SERVICING NUCLEAR POWER PLANT WITH SELF-CONTAINED POWER UNITS Russian patent published in 1996 - IPC

FIELD: nuclear power engineering. SUBSTANCE: full-power operation of all power units of plant is performed in common space wherein power units are installed in in-line arrangement along space. Each reactor core is replaced by new one in other space whereto units are floated in turn by water from first space. Power unit with new core is brought to full power in first space whereto it is floated by water from second space over water area. Room for power unit conveyed into first space is cleared by displacing each unit aside towards exit to second space. EFFECT: simplified arrangement of nuclear power plant, reduced labour consumption for maintenance of power units without impairing their safety. 2 cl, 3 dwg
