| titleOfInvention | Shroud tank and fill pipe for a boiling water nuclear reactor |
| abstract | A shroud tank (60) and fill pipe (66) for a boiling water nuclear reactor (2) of the type having a reactor vessel (38) containing a saturated water coolant inventory, a reactor core (36) for heating water to generate a steam/water mixture, a steam separator (34) for classifying said steam and water from the steam/water mixture, and standpipes (37) for conveying the steam/water mixture from the core (36) to the steam separator (34). The shroud tank (60) is disposed inside the reactor vessel (38) overlying the reactor core (36) and circumscribing the standpipes (37). The shroud tank (60) has an open top, a closed bottom, and a plurality of drain holes around its bottom periphery. During normal reactor operation, the shroud tank (60) is supplied with cold water coolant which is continuously introduced at relatively low flow rates into the shroud tank through the fill pipe (66). The drain holes are sized to minimize the outflow of cold water coolant during normal operation. During a loss of coolant accident, the drain holes release cold coolant to cool the reactor core (36) when the "hot" coolant level drops below the drain holes. Because of the substitution of cold coolant, the amount of reactor coolant lost because of flashing during depressurization is reduced. The reduction of lost coolant permits relaxation of the volume, height, containment, and primary emergency core cooling requirements for the reactor. |
