The invention provides an irradiation surveillance sample positioning, clamping and cutting method. The irradiation surveillance sample positioning, clamping and cutting method comprises the steps that a hand wheel on a horizontal moving arm is rotated after positioning is completed, and a whole cutting assembly is driven through a lead screw mechanism to move forwards and backwards till a front-back positioning sensor gives an alarm; a hand wheel on a vertical box of a cross rotating and moving mechanism is rotated, and a whole middle moving body is driven through the lead screw mechanism to move downwards, so that the cutting assembly on the horizontal moving arm is driven to move downwards till an up-down positioning sensor gives an alarm; after up-down positioning is completed, a cutting assembly hand wheel is rotated, a plug pin is inserted into a irradiation surveillance sample positioning hole till a plug pin positioning sensor gives an alarm; and after plug pin positioning is completed, the cutting assembly hand wheel is rotated, a clamping mechanism on the cutting assembly is driven to act, so that an irradiation surveillance sample box is clamped, and a cutting head is started after the irradiation surveillance sample box is clamped. The invention further provides an irradiation surveillance sample positioning, clamping and cutting device.
Description
technical field [0001] The invention relates to the field of maintenance of nuclear power plant equipment, in particular to a device for positioning, clamping and cutting samples for irradiation supervision and a method thereof. Background technique [0002] During the operation of the nuclear power plant, during the whole life cycle of the reactor pressure vessel, it is necessary to regularly sample the radiation supervision samples to verify the state of the pressure vessel. According to the radiation surveillance program, the irradiation surveillance samples need to be taken out from the reactor for testing on a regular basis, in order to verify that the reactor pressure vessel can maintain structural integrity under both normal and accident conditions. Under such a high radiation dose, it is impossible for people to position and hold the radiation supervision sample at close range. In order to ensure the sampling of the radiation supervision sample, it is necessary to us...
