This report presents the results of a literature survey of cracking of alloy 600 components in PWR plants. Alloy 600 cracking of S/G tubes and/or plugs has been previously addressed. This report focuses on incidents occurring primarily in the pressurizer region. It documents these problems and recommends utility actions to address the issue of PWSCC of alloy 600 components in the primary system. Cracking problems have occurred both domestically and abroad. Information provided for each event includes plant, affected component, date of incident, plant date of commercial operation, detection method, outcome, remedial actions, and number of components cracked. Incidents are reported for US plants including San Onofre Nuclear Generating Station Unit 3, St. Lucie Unit 2, Arkansas Nuclear One Unit 2, and Calvert Cliffs Unit, and for Electricite de France. 38 refs., 21 figs., 3 tabs.
