Tank Farms at the Savannah River Site

Section 3116 of the Ronald W. Reagan National Defense Authorization Act for Fiscal Year 2005 authorizes the Secretary of Energy, in consultation with the Nuclear Regulatory Commission, to reclassify certain waste from reprocessing spent nuclear fuel from high-level waste to low-level waste if it meets the criteria set forth in Section 3116.  A Waste Determination Basis (WD Basis) provides the analysis to document the Secretary's determination to manage the residuals as low-level radioactive waste.

The Savannah River Site has several facilities managed under Section 3116. The F-Area Tank Farm (FTF) WD Basis covers 20 tanks remaining to be closed in the FTF and the H-Area Tank Farm (HTF) WD Basis will cover all 29 HTF tanks.

Several technical documents describing the facility and how it will be closed in a safe and low risk manner are issued for each facility. These documents estimate the future risk to a member of the public over thousands of years based on assumptions regarding how well DOE is able to clean the tanks and what estimated residuals remain. These facilities are also regulated by the State of South Carolina and Environmental Protection Agency, Region IV and other documents are submitted to the regulators for approval prior to any final actions taken. Also, prior to closure of the tanks, actual samples are analyzed and compared to the estimates in the technical documents and the long-term risks are re-evaluated to verify that there is no additional risk to the public based on final residuals. These documents are submitted to the regulators to gain their approval to close the tanks.

NRC issued their consultative Technical Evaluation Report (TER), on October 27, 2011, and it is available on the NRC electronic reading room at http://www.nrc.gov with an ADAMS accession number of ML112371715. Also, available on the NRC electronic reading room, are the NRC Request for Additional Information (RAI) with the DOE responses to those RAIs.

A National Environmental Policy Act (NEPA) Record of Decision (ROD) was supplemented to reflect that the tanks are being closed under the requirements of Section 3116 in addition to those requirements in DOE Order 435.1. This is the only decision modified by this supplemental ROD.  A copy of the NEPA Supplement Analysis is available on the web site, http://www.srs.gov/general/pubs/envbul/nepa1.htm.
