摘要
PURPOSE: A thermal shock preventing apparatus with a condensed water-mixing storage tank is provided to re-collect steam discharged when a main steam safety valve is open, thereby utilizing the steam for condensate water flowing inside a steam generator. CONSTITUTION: A thermal shock preventing apparatus includes a steam generator(100), a steam supplying pipe(120), a condensate water tank(110), a condensate water collecting pipe(130), a bypass pipe(400), and a mixing storage tank(300). The steam supplying pipe collects discharged main steam. A heat exchanger(200) is built in the condensate water tank. The heat exchanger condenses the collected steam. The condensate water collecting pipe supplies condensate water, which is generated from the condensed steam, as makeup water to the steam generator. The bypass pipe is installed on the end portion of the condensate water collecting pipe. The bypass pipe supplies the condensate water to the steam generator. The mixing storage tank stores hot water, and restrains the generation of thermal shocks in the steam generator.
