DRIVEN-TYPE AUXILIARY CONDENSER IN NUCLEAR POWER PLANT

PROBLEM TO BE SOLVED: To provide a driven-type auxiliary condenser in a nuclear power plant that prevents vibration and shock waves from being generated, by preventing steam from being mixed with water re-entering a steam generator in a process for removing core decay heat (or residual heat) with a...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a driven-type auxiliary condenser in a nuclear power plant that prevents vibration and shock waves from being generated, by preventing steam from being mixed with water re-entering a steam generator in a process for removing core decay heat (or residual heat) with a driven type method even if power supply is interrupted when an accident occurs.SOLUTION: A driven-type auxiliary condenser in a nuclear power plant comprises: a steam generating unit that causes supplied water to vaporize by heating with heat being generated when a nuclear reactor is operated; a water-cooling type heat exchange unit that is connected to the steam generating unit and inside which cooling water is stored so that steam supplied from the steam generating unit is cooled down and condensed; and a steam-water separation tank whose one side is connected to the water-cooling type heat exchange unit and whose other side is connected to the seam generating unit, and that is provided so that only water can be supplied to the steam generating unit by separating water from steam even if water and steam are mixed and entered from the water-cooling type heat exchange unit.
