If there's an emergency and you lose all the power to your nuclear power plant, the little blower stops blowing, the frozen plug of salt melts, and the liquid fluoride fuel inside the reactor drains out of the vessel, through the line and into another vessel called a drain tank.
Se há uma emergência e perdemos toda energia da planta nuclear, esse gás para de circular, a tampa de sal congelada derrete, e o combustível de fluoretos líquidos do reator escoa dessa para outra câmara chamada tanque de drenagem.
