The distributing orderliness of formed shell thickness has been found by analyzed data of shell thickness after forming. Then, based on the nuclear safety and economics, the cause of over-size on spherical shell clad steel plate thickness of AP1000 accumulator tank during the pressed forming is analyzed in terms of design and manufacture. The evaluation on safety of accumulator tank, and the improvement technical measures are presented for avoiding the over-size issue: on the one hand, the forming technique is optimized by test and simulation calculation; on the other hand, the nominal thickness of propriety shell shall be decided by calculation.
