| event text = Double Contingency Protection: Double contingency protection for the ADU Bulk Blending System is assured by (1) preventing moderator from becoming available to a bulk container, and (2) preventing moderator from entering a bulk container. The first contingency did not occur because the moderator was never available to a bulk container. Moderator is prevented from entering a bulk container by preventing high moisture polypaks from being dumped into the bulk container. The polypaks are processed through a scan and dump interlock, which prevents unacceptable polypaks from being dumped. The software malfunction left less than previously documented double contingency protection for the system. In accordance with Westinghouse Operating License (SNM-1107), paragraph 3.7.3 (c.5a), this event satisfies the criteria for a 24-hour notification. | | event text = Double Contingency Protection: Double contingency protection for the ADU Bulk Blending System is assured by (1) preventing moderator from becoming available to a bulk container, and (2) preventing moderator from entering a bulk container.
