Abstract

PURPOSE:To simplify a device by starting a buffer operation just before the full insertion position of a control rod and measuring the buffer time by using position detecting reed switches just before the full insertion position and a full insertion position detecting reed switch. CONSTITUTION:The position detecting reed switches 101 are operated successively from below by a magnet 31 to continuously detect the position of the control rod 7 at the time of a scram. The top end face of a drive piston 8 comes into contact with the bottom end face of a buffer piston 102 right after the reed switch 101 of '01' just before the full insertion position '00' of the control rod 7 turns on. The buffer operation is then inserted. Whether the buffer operation is normal or not is then detected by measuring the time t1 until the '00' position detecting reed switch 101 turns on and off. The reed switches for measuring the buffer time are saved and the device is simplified by constituting the mechanism in such a manner.
