Based on the basic parameter of NAC-STC spent fuel transport container, the model of spent fuel transport container, 17×17 spent fuel component of pressurized water reactor and simple mannequin, is constructed by MCNP code, and the equivalent dose of motorman and worker is calculated respectively. Results show that equivalent dose of motorman whose distance from spent fuel transport container impact limiter to himself is one meter is 1.82 mSv/a, that equivalent dose of worker whose distance from spent fuel transport container center to himself...
