Reportable occurrences at nuclear reactors and their causes

Reports on reportable occurrences at nuclear reactors are submitted to the Nuclear Regulatory Commission (NRC), and these reports are accessioned and reviewed by the Nuclear Safety Information Center at Oak Ridge National Laboratory. A list of reportable occurrences during September and October 1977 which involved reactor shutdowns is presented. Included in the list are occurrences at operating research reactors and commercial power reactors. Only those occurrences involving reactor shutdowns are listed
