| Event Description | The following information was provided by the licensee via mail:
It was determined that the Urenco United States of America (UUSA) safety analysis did not analyze for stacked, criticality safe (CSA) containers when not in an engineered storage array. This potentially results in an inadequate analysis. Urenco USA stores CSA containers in isolation on the floor and spaces them 60 centimeters apart, prior to performing IROFS [Items Relied on For Safety] 58a mass determination and placing a container in an array. However, an analysis has not determined whether dropping a container, or stacking a container, onto another container stored in this way, could result in exceeding the Code of Federal Regulations Title 10 Part 70.61 requirements. Currently, there are no containers stacked in this way. Urenco USA has stopped all work regarding moving the containers in areas affected by accident sequence DS1-9. The plant is in a safe and stable condition. |
