          Radioactive Waste  Waste Incidental to Reprocessing  Disposal Process  WIR LocationsNDAA Section 3116 Waste Incidental To Reprocessing (WIR) at The Idaho National Laboratory (INL) in Idaho – Idaho Nuclear Technical and Engineering Center (INTEC) Tank Farm Facility (TFF)
**INL INTEC TFF in Butte County, Idaho**

			**Operator:** U.S. Department of Energy**Docket Number:** PROJ0735**Tank Description**: Eleven larger and four smaller stainless steel tanks**Waste Volume**: each larger tank capacity of approximately 1.14x106 Litres (300,000 gallons), each smaller tank capacity of approximately 1.14x105 Litres (30,000 gallons), and total capacity of 15 tanks approximately 1.29x107 Litres (34,200,000 gallons)Under Section 3116(b) of the Ronald W. Reagan National Defense Authorization Act for Fiscal Year 2005 (NDAA), the U.S. Nuclear Regulatory Commission (NRC), in coordination with the NDAA-Covered State monitors the U.S. Department of Energy (DOE) disposal actions to assess compliance with the NRC regulations in Title10 of the *Code of Federal Regulations* (10 CFR) Part 61, "Licensing Requirements for Land Disposal of Radioactive Waste," Subpart C, "Performance Objectives (POs)." The NDAA-Covered States are currently Idaho (ID) and South Carolina (SC).

The Idaho National Laboratory (INL) Site is an approximately 2,305 square kilometer (km)2 (890 square mile (mi2)) location owned by the U.S. Government that is in southeastern ID. The Idaho Nuclear Technical and Engineering Center (INTEC) is located approximately 29 km (18 mi) from the nearest INL Site boundary.

There are 15 waste storage tanks at the INL INTEC Tank Farm Facility (TFF). In addition, there are interconnecting transfer piping, and secondary containment components for the transfer piping. Placed into service between 1953 and 1966, the 11 larger tanks (i.e., designated as WM-180 – WM-190) are approximately 15.2 meters (m) (50 feet (ft.)) in diameter and 6.4 – 7.0 m (21 – 23 ft.) in height. Nine of the larger tanks are constructed of Type 304L stainless steel and the other two (i.e., WM-180 and WM-181) are constructed of Type 347 stainless steel. The four smaller stainless steel below-grade storage tanks (i.e., WM-103 – WM-106) were constructed on reinforced concrete pads in 1954 and removed from service in 1983. Those four smaller tanks are horizontal cylinders approximately 3.5 m (11.5 ft.) in diameter and 11.6 m (38 ft.) in length. All 11 of the larger tanks are housed in concrete vaults approximately 13.7 m (45 ft.) below grade, while the 4 smaller tanks have no vaults.

The DOE began cleaning the tanks in 2002. Currently, waste retrieval and grouting were completed for 7 of the 11 larger tanks (i.e., WM-180 – WM-186), all 4 of the smaller tanks, and the associated ancillary equipment for those 11 cleaned-out tanks. Four of the larger tanks (i.e., WM-187 – WM-190) have not yet been cleaned. The DOE assumed that those four tanks will be cleaned as efficiently as the other seven larger tanks were cleaned. Three of those four tanks are considered 100 percent (%) full and one is maintained as a spare, considered to be about 20% full. After the bulk sodium-bearing waste is transferred from each of those four tanks, the DOE plans to initiate waste removal operations to reduce the residual tank waste heels to the maximum extent practical. After cleaning activities are completed for all four of those tanks and their ancillary equipment, the DOE plans to stabilize the INL INTEC TFF by filling the tank system with grout and then closing the INL INTEC TFF at some future time.
