A simulated spent fuel storage tank for a nuclear power station, the simulated spent fuel storage tank comprising: a simulated storage tank, simulated spent fuel components accommodated in the simulated storage tank, and an electric heater, wherein the simulated spent fuel components are electrically connected to the electric heater by means of cables. The simulated spent fuel storage tank for a nuclear power station can be used for thermal property testing and operation training tests. The arrangement state and the thermal power of spent fuel components can be precisely simulated on the basis of the actual loading and storage quantity and the heat release quantity of the spent fuel components, and the thermal property testing of a spent fuel storage tank is achieved. Vacuum drying, automatic welding, and cutting and retrieval operations in a real heating environment can also be simulated, and a real spent fuel component load is simulated in order to perform storage tank transfer and storage operations, such that the skill level of operators can be improved, thereby preventing the occurrence of incidents caused by human factors.
