Abstract: A travelling spent resin incepting device was developed to assure the timely and safe emission of radioactive spent resin. The device has some characteristics such as travelling, integration etc., and the function of the device can be achieved with severe environment. 3D analysis model of the device was built in the development process with ANSYS code which is a finite element analysis software, modal and response spectrum analyses were carried out, and stress intensity of the device by different loads under designed condition was obtained, and stress strength assessment for the device structure based on RCC-M was also carried out. The results indicate that the strength of the device satisfies requirements of the RCC-M level O rule under designed condition, and the spent resin reception and safe transport for the device were verified by experiments.
