Abstract

Abstract: The size of the LP cylinder of steam turbine of AP1000 unit in Sanmen Nuclear Power Company Limited is larger than general ones. So the deformation of its components increases relatively, and the problem of the deformation control after the cylinder was disintegrated must be considered. The deformation control technology in LP cylinder overhaul was introduced. The measurement result of the deformation shows that the technology is effective.

Key words: steam turbine, low pressure (LP) cylinder, deformation control technology, deformation, lifting jack, hydraulic pull rod
