Abstract:
Neutron diffraction method was used to measure the residual stress of the aluminum weld of the retired reactor, and the effect of irradiation on the residual stress of aluminum weld was studied. Test result indicates that the maximum residual stress is located in the heat affected zone, the greater the reactor irradiation dose, the greater the oscillation of the residual stress of aluminum weld center from compressive stress to tensile stress. At the position far away from the weld position, the strain of the irradiated samples is not zero.
