Starting from Project 728 in early 1970s，shanghai nuclear power industry，walked through the initiating and expanding stage，and has realized a leaping development after more than 40 years hard way. In this paper，we review the way we walk through，and divide the development history of Shanghai Electric nuclear power industry into three stages：hard starting，speeding development and promotion. Shanghai Electric has realized an independent development road of nuclear power equipment manufacturing from 300MW，600MW to 1000MW by combination of R&D and technology introduction.
