Study on Planeness Deviation of Bottom Steel Liner in Nuclear Power Plant Containment during Construction

In this paper, the method of planeness deviation analysis in the construction stage of the bottom steel liner is adopted to calculate the bottom steel liner of different sizes, the limit value of the planeness deviation of the bottom steel liner of different sizes is obtained. Calculation results are compared and the analysis shows that the planeness deviation in the bottom steel liner is related to the size of the block. Different planeness deviations can be used according to different block schemes.
