Abstract
1434384 Nuclear reactors SIEMENS AG 11 July 1973 [14 July 1972] 33134/73 Heading G6C In a nuclear reactor installation, a spray system has outlets within the reactor pressure vessel for the purpose of cooling melted core material. The reactor is a gas- (e.g. helium) cooled fast breeder. In one embodiment (Fig. 1) fuel elements are secured by means of a holding device 10 comprising tubes 12 through which coolant gas normally is fed towards the core 4. The coolant circulates within the concrete pressure vessel 2, as indicated by arrows 16, so as to pass in heatexchange relation with a steam-generator 15. The lower part of the shield 3 within the vessel 2 forms a tank 20 which receives core material, should this fuse, and prevents accumulation of a critical size. Water is sprayed into the vessel 2 via the tubes 12 in the event of core meltdown, the steam generated passing to the generator 15; a one-way valve ensures continuance of the (arrowed) flow pattern. A larger tank 25 is provided to receive debris should the core melt its way through the base of tank 20 and the vessel wall supporting the latter; additional cooling means may be provided in tank 25. Should steam not be routed through the steamgenerator 15 as described, it may be released into the interior of the steel containment 1 and heat removed therefrom by water emanating from an external sprinkler system 28. In another embodiment (Fig. 2) water can be sprayed into tank 20 from lines 30, 31 within the vessel 2. After passing through the steamgenerator 15, excess steam can pass to the exterior of the vessel 2 via an aperture 36 to give up heat to the surrounding steel containment.
