During the course of the W-130 Stabilization and Ventilation Project conducted at the Waste Encapsulation Storage Facility (WESF) unanticipated radiological events occurred which significantly delayed the completion of the Project. During the 4th grout lift for one of the hot cells an activated particle was transferred from the hot cell into the Temporary Ventilation System (TVS) ducting. This resulted in significant radiation levels in the WESF Canyon. An underlying cause to this event was inadequate planning during the early stages of project planning and integration of controls into design elements.

Lesson Learned: Incorporation of controls into project design early in the process is essential to the development of appropriate controls and work efficiency.
