EPR核电站安全壳内部换料水池天花板的焊接

摘要

Taishan EPR nuclear in - containment refueling water storage tank ( IRWST ) adopts one - side welding with back formation welding process, which is the first time used in the construction field of stainless steel pool in the nuclear power station. The problems and solutions in the welding procedure and welding process for the IRWST pool ceiling were introduced, which will offer a good pattern for welding works of the nuclear power station stainless steel pool in the future.%台山EPR核电站安全壳内部换料水池(简称:IRWST水池)采用单面焊双面成形焊接工艺,该工艺属世界核电站不锈钢水池建造领域首次采用.简要介绍了IRWST水池天花板的焊接工艺和焊接过程中出现的问题与解决措施,希望对以后核电站不锈钢水池的焊接起到一定的借鉴作用.
