| event text = The Hematite Decommissioning Project (HDP) is excavating burial pits containing enriched uranium. HDP has established criticality safety controls to ensure the safe handling of the buried waste as it is excavated. These controls involve redundant surveys and visual inspections at the time of excavation. These controls failed to identify an item upon excavation that was 400,000 ncpm [net counts per minute] on contact and had dimensions of 6 inches or greater. Instead, the item was identified and placed in criticality safety controls (collared drum) after it had reached the Waste Holding Area. | | event text = The Hematite Decommissioning Project (HDP) is excavating burial pits containing enriched uranium.

The item appeared to be a crushed container, estimated at 10 gal. in original size, and had contents primarily consisting of gloves and plastic. After the contents were removed, the empty container was confirmed to have only contamination that was below the threshold of criticality safety controls. The detailed assay of the contents was 22 g of U-235, which does require criticality safety controls. | The item appeared to be a crushed container, estimated at 10 gal. in original size, and had contents primarily consisting of gloves and plastic.
