The invention relates to the technical field of cables for nuclear power stations, and discloses a modified crosslinked polyethylene insulated anti-radiation power cable for a nuclear power station in order to solve the problems that in the prior art, an insulating layer of a power cable for a nuclear power station needs irradiation crosslinking, the preparation process is complex, and the production period is long, and the modified crosslinked polyethylene insulated anti-radiation power cable for the nuclear power station comprises a cable core which comprises a plurality of conductors. The surface of each conductor is wrapped with an insulating layer, the space between the conductors is filled with filler, and the filler is sequentially wrapped with a flame-retardant belt and a sheath layer. The cable can meet the use standard of a power cable for a nuclear power station, and is good in radiation aging resistance and high temperature aging resistance and long in service life; and irradiation crosslinking is
