Abstract

1448071 Nuclear reactors SIEMENS AG 26 Feb 1974 [30 March 1973] 8699/74 Heading G6C In a nuclear reactor installation, especially one including a PWR, there is provided a first auxiliary coolant supply system whereby auxiliary coolant can be introduced into a steam generator, and/or a second auxiliary coolant supply system whereby auxiliary coolant can be introduced into the reactor core. In the embodiment shown, auxiliary coolant from a variety of alternative sources (such as a sump 19, fuel storage tank 60, pressurizer 30 and header tank 40) can be introduced, as appropriate to circumstances, via conduits and non-return valves, into: (1) an outlet chamber 12 of steam generator 10-through spray means 57-so as to enter "cold" legs 14, 14<SP>1</SP> which lead the coolant to the pressure vessel 1; (2) a "hot" leg 9-so as to debouch into a trough 27 above the core 5, the trough 27 having apertures for directing coolant against the inner surface of core container 4; (3) the space above the core, via pipes having spray apertures 55a directed towards the wall of an above-core structure 6; (4) into the core, via pipes 52; and (5) into the reactor building, via spray means 68. Water from tank 40 has to pass through a container 42 containing boric acid solution for effecting reduction of reactivity of the reactor. A plug-andsocket connection 51 enables easy removal of the pressure vessel cover 2 for fuel changing. Various elements of the different systems are described in detail.
