The Utah Low Level Radioactive Waste Disposal Process (15 KB) chart tracks the waste acceptance and disposal process for LLRW shipped to EnergySolutions for land disposal at its Clive facility.
Each waste generator is required by the:
- Nuclear Regulatory Commission (NRC);
- state in which the generator is located; and,
- the Division of Radiation Control (DRC) Generator Site Access (GSA) permit,
to accurately record the radioactivity levels of individual radioactive isotopes present in the waste material. The generator is also required to characterize waste for purposes of disposal. Waste must be packaged, labeled, and placarded according to the U.S. Department of Transportation (USDOT) and GSA requirements. State and federal regulations require the generator to properly classify waste intended for disposal as Class A, B, or C. The generator completes a Waste Profile Form that it must send to EnergySolutions for approval prior to shipment. Once the generator finalizes the waste shipment documents and receives approval to ship its waste to the Clive facility, it sends a waste manifest to Clive three days before shipping. EnergySolutions runs calculations based on the information in the manifest to ensure the waste has been properly classified and enters this pre-shipment data into it’s Electronic Waste Information System (EWIS).
Utah and the NRC have adopted the applicable USDOT transportation requirements for shipments of low-level radioactive waste.
Waste Arrival and Acceptance at Disposal Facility
DRC is present during sampling and inspection of waste arriving at the Clive facility. This includes visually inspecting waste containers for physical defects and potential leaks. Both DRC and EnergySolutions take an exposure rate measurement and contamination wipes to determine compliance with USDOT requirements and values listed on the manifest. Inspectors check shipping papers to ensure that the manifest is complete and consistent with pre-shipment information. The DRC samples the waste (if required) once the shipment has been taken to the restricted area and can be managed safely.
DRC requires EnergySolutions to have an approved waste characterization plan that includes sampling frequencies for incoming waste. DRC is frequently present during this sampling. Samples are sent to independent labs, which in turn send the results to DRC. The waste is held at EnergySolutions until the lab results come back. If the waste is greater than Class A, it is returned to the generator. If the waste meets Class A requirements, it is disposed of at the Clive facility.
