BURST SLUG DETECTION MEANS FOR A LIQUID PHASE COLED NUCLEAR REACTOR COMPOSED OIF A VERTICAL REACTOR CELL HAVING FUEL RODS AND MEANS FOR CAUSING THE FLOW OF COOLING LIQUID IN SUCH CELL UPWARDLY PAST THE FUEL RODS THEREOF AND INTO THE UPPER PORTION OF SUCH CELL TO A PLACE OF DISCHARGE THEREFROM, SAID DETECTION MEANS COMPRISING MEANS FOR FEEDING A GAS CAPABLE OF ENTRAINING GASEOUS FISSION PRODUCTS CONTAINED IN THE COOLING LIQUID, INTO CONTACT WITH COOLING LIQUID CONTAINED IN A PORTION OF SUCH CELL LOCATED BETWEEN THE VICINITY OF THE TOPS OF THE FUEL RODS THEREOF AND THE UPPER END OF SUCH CEL, MEANS FOR CONDUCTING COOLING LIQUID FROM A POINT LOCATED BETWEEN THE FUEL ODS AND SAID PLACE OF DISCHARGE OF SUCH LIQUID FROM THE CELL, UPWARDLY PAST SUCH PLACE OF DISCHARGE AND THROUGH THE LEVEL OF THE COOLING LIQUID IN SUCH CELL TO AN ELEVATED POINT IN SAID CELL LOCATED SUBSTANTIALY ABOVE SUCH LIQUID LEVEL, AND FOR DISCHARGING THE THUS CONDUCTED COOLING LIQUID INTO THE CELL AREA ABOVE SUCH LEVEL, SAID FEEDING MEANS BRINGING THE GAS INTO THE CELL AT A PLACE LOCATED BETWEEN SUCH LEVEL AND SAID ELEVATED POINT SO THAT IS IS CONTACTED BY THE COOLING LIQUID MOVING FROM SUCH POINT TOWARD SAID LIQUID LEVEL, MEANS POSITIONED BETWEEN SAID ELEVATED POINT AND THE PLACE WHERE THE GAS IS BROUGHT INTO SAID CELL FOR CAUSING THE GAS AND LIQUID TO FLOW IN OPPOSITE DIRECTIONS IN SUCH INTIMATE RELATION AS TO ENABLE THE GAS TO ENTRAIN ANY GASEOUS FISSION PRODUCTS CONTAINED IN THE LIQUID, MEANS FOR WITHDRAWING THE GAS WITH ANY GASEOUS FISSION PRODUCTS ENTRAINED THEREIN FROM AN UPPER PORTION OF SUCH CELL SPACED ABOVE THE FUEL RODS THEREOF, AND MEANS FOR MEASURING THE ACTIVITY OF THE GASEOUS FISSION PRODUCTS IN THE WITHDRAWN ENTRAINING GAS.
