United States of America [Experiences from international projects on the decommissioning of both large and small facilities]. Annex V

Numerous lessons learned were identified and implemented during the course of these projects: — Produce a clearly defined scope of work and set of goals, which demands a thorough planning process. — Assign decision authority and individual accountability to complete project tasks. — Use a flexible work plan structure (e.g. work stage modules) to allow project plans to be easily modified to address new discoveries and changing site conditions. — Perform pre-entry briefings to help ensure that personnel understand and effectively execute their responsibilities. — Plan and perform work using clear, effective, closed loop communications, which is essential for success (i.e. communicate, communicate, communicate!). — Conduct crew briefings to emphasize stop work authority and attention to detail, for example, donning/doffing techniques and performing detailed PPE inspections before each entry and during cutting/repackaging operations to prevent cross-contamination. — Monitor floor and airlock contamination levels within the enclosure to verify that the contamination does not spread, and apply fixatives as needed. — Install a portable frisker at the step-off pad to survey the employee's shoes for contamination. — Frequently change or replace temporary sticky pads on the floor in the work areas to minimize buildup of radioactive contamination. — Install a camera to critique work practices within the containment enclosure. — Use an HEPA vacuum cleaner to remove debris. — Have backup equipment (e.g. an air distribution box) available in the event of a malfunction
