SURVEY OF PIPING FAILURES FOR THE REACTOR PRIMARY COOLANT PIPE RUPTURE STUDY

摘要

An industrial piping failure survey covering 701 contacts in electric utilities, petroleum refineries, chemical processing, marine applications, architect-engineers, component manufacturers, piping fabricators and erectors, insurance companies, and others was conducted as part of the Reactor Primary Coolant Rupture Study. The total of 315 replies received, when combined with published failure cases, provided 399 failure case histories of interest to the study. The term, "failure" was defined as any defective condition encountered during start-up, testing, and/or service that required repair or replacement corrective action.
