Condenser extraction steam line expansion joint (bellows assembly) degradation is an unanticipated problem many older stations must pass to ensure their ability to operate reliably and cost effectively. The uncertainty of bellows assembly integrity is unexpectedly developing into a major concern for many utilities facing the upcoming challenges of utility degradation. The Dresden Nuclear Station recently accomplished a major industry milestone by completing the first phase of a two-part effort to replace its Unit 2 extraction steam bellows assemblies during a 41-day refueling outage. The first phase, consisted of a large-scale replacement of 24 vertical bellows assemblies, is discussed.
