Nuclear reactor. [PWR]
Patent
·
OSTI ID:7355942
Coolant fluid within the nuclear reactor described is fed under pressure to the lower end of the guide tubes. Control rods are disposed within the guide tubes and are movable hydraulically by means of the pressure transmitted from the lower end of the guide tubes. This pressure supports the control rods and tends to move them up, out of the guide tubes and out of the adjacent core. As a result of this arrangement, in event of malfunction or accident causing a loss of pressure, the control rods are not withdrawn from the guide tubes but, instead, are further inserted into the guide tubes and into the core. 6 claims, 9 drawing figures.
