<p>1,198,090. Reactors. COMBUSTION ENG. Inc. 28 Dec., 1967 [29 Dec., 1966], No. 58877/67. Heading G6C. An arrangement for the removal of steam arising from the rupture of the pressure vessel 10 of a water-cooled reactor disposed in shielding 14 within a containment 12, comprises connecting the space within the containment to one or more condensers 16 through pipes 18 and normally-open valves 20, the condensers having spray nozzles 26 connected through a normally-closed valve 30 to a water storage tank 24. Should the vessel 10 burst the rise in pressure in containment 12 causes automatic opening of the valve 30 to condense steam entering the condensers 16. The condensate may return to the pressure vessel through the pipes 18 or may be removed through pipes 34. The atmosphere in the containment 12 is circulated through a valve 38, pump 36, refrigerator 47, filtering means 40, pipe 42 and valve 44. When the radioactivity of this atmosphere has sufficiently decreased as detected by monitors 48, the atmosphere is discharged through a stack by opening valve 46 and closing valve 44.</p> |
