Abstract

This paper discusses the causes of AP1000 Steam Generator（SG） tube sheet underclad cracking.Base metal weldability,hydrogen influence,welding techniques and weld residue stresses are all discussed in details in contributing to the underclad cracking problems.Feasible and realistic improvement plans are proposed for the AP1000 SG tube sheet cladding,including the controlling forging procurement,welding process and cladding techniques.
