Abstract

951,896. Nuclear reactors. SOC. ANGLOBELGE VULCAIN S. A. Jan. 29, 1963 [Feb. 7, 1962], No.4795/62. Heading G6C. A nuclear reactor plant employing a pressurised liquid coolant/moderator circulated in a closed flow circuit which makes a pass through a reactor pressure vessel, is provided with a connection communicating the highest point within the pressure vessel with a confined volume containing a constant mass of gas which acts upon the free surface of the coolant/moderator liquid within the pressure vessel, the pressure of the gas being such that at minimum temperature the circuit is maintained in a primed condition. In the arrangement shown coolant/moderator circulates through the reactor core 1 from an inlet 3 to an outlet 4 and then flows through a heat exchanger 7 and pump 6 back to the inlet. The top of the pressure vessel 2 is connected by a small bore pipe 10 to a closed pressuriser compartment 11 for helium gas. In priming the circuit coolant is pumped into the pressure vessel from tank 18 through valve 16a until it reaches the level LWL. Valves 8, 9 and 16a are then closed, the reactor core is fuelled, the control rods are connected to their drives, and the pressure vessel is resealed. Valves in pipes 15a, 15b are opened to connect the pressure vessel and heat exchanger to a vacuum pump 15 which removes air from the circuit. The pressuriser compartment and pressure vessel are filled with helium from a high pressure supply 13, and pumping of the coolant from tank 18 is continued until the pressure vessel contains sufficient coolant to fill the rest of the circuit under cold conditions. Valve 8 is then opened to allow the circuit to fill, valve 9 is opened and pump 6 started; the reactor is started, and at full operating temperature the coolant will rise to the level HWL. When the reactor is shut down the coolant level falls again but the pressure of the helium gas maintains the continuity of the coolant through the whole flow circuit and the pump 6 can be kept running to dissipate shut-down heat. The coolant may be a mixture of light and heavy water.
