AP1000 nuclear power plant post construction erecting type heavy duty shielding gate erection technology

Abstract

Abstract:

Abstract:AP1000 nuclear power plant shielding gate is equipped as safety shielded tunnel between houses of nuclear island,but struggled with big gate size,high installation precision,restricted installation space.Simulating lifting & erection and special designed installation equipment and other measures was adopted.And two gates over barrier simultaneously erection,outdoor non support joint lifting and other unconventional erection plan was carried out.Heavy duty shielding gate erection was realized.This erection plan is appropriate for the erection of nuclear power plant post construction erecting type heavy duty shielding gates with restricted space,lifting failure.
