The present invention provides a bottom closure of a reactor pressure vessel and a preparation method therefor. The bottom closure of a reactor pressure vessel comprises a bottom closure body and a porous coating applied on the outer wall surface of the bottom closure body. An end portion of the bottom closure body is connected to a barrel section of a reactor pressure vessel. According to the bottom closure of the reactor pressure vessel and the preparation method therefor in the present invention, the critical heat flux density of the outer wall surface of the reactor pressure vessel is increased, thereby facilitating the implementation of an in-vessel molten material retention technology and improving the safety of nuclear power plants even in severe accident scenarios.
