Available in PDF, EPUB and Kindle. Book excerpt: Due to significant delays in constructing and operating the Waste Treatment Plant, which is needed to support retrieval of waste from Hanford's single shell tanks (SSTs), SSTs may now be required to store tank waste for two to three more decades into the future. Many SSTs were built almost 70 years ago, and all SSTs are well beyond their design lives. Recent examination of monitoring data suggests several of the tanks, which underwent interim stabilization a decade or more ago, may be leaking small amounts (perhaps 150-300 gallons per year) to the subsurface environment. A potential leak from tank T-111 is estimated to have released approximately 2,000 gallons into the subsurface. Observations of past leak events, recently published simulation results, and new simulations all suggest that recent leaks are unlikely to affect underlying groundwater above regulatory limits. However, these recent observations remind us that much larger source terms are still contained in the tanks and are also present in the vadose zone from historical intentional and unintentional releases. Recently there have been significant improvements in methods for detecting and characterizing soil moisture and contaminant releases, understanding and controlling mass-flux, and remediating deep vadose zone and groundwater plumes. To ensure extended safe storage of tank waste in SSTs, the following actions are recommended: 1) Improve capabilities for intrusion and leak detection. 2) Develop defensible conceptual models of intrusion and leak mechanisms. 3) Apply enhanced subsurface characterization methods to improve detection and quantification of moisture changes beneath tanks. 4) Maintain a flux-based assessment of past, present, and potential tank leaks to assess risks and to maintain priorities for applying mitigation actions. 5) Implement and maintain effective mitigation and remediation actions to protect groundwater resources. These actions will enable limited resources to be applied to the most beneficial actions. A systems-based approach will support extended safe storage of tank waste, reduce the risks from tank leaks, and protect human health and the environment.

Download or read book Functions and Requirements for Single shell Tank Leakage Mitigation written by and published by . This book was released on 1994 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document provides the initial functions and requirements for the leakage mitigation mission applicable to past and potential future leakage from the Hanford Site's 149 single-shell high-level waste tanks. This mission is a part of the overall mission of the Westinghouse Hanford Company Tank Waste Remediation System division to remediate the tank waste in a safe and acceptable manner. Systems engineering principles are being applied to this effort. A Mission Analysis has been completed, this document reflects the next step in the systems engineering approach to decompose the mission into primary functions and requirements. The functions and requirements in this document apply to mitigative actions to be taken regarding below ground leaks from SST containment boundaries and the resulting soil contamination. Leakage mitigation is invoked in the TWRS Program in three fourth level functions: (1) Store Waste, (2) Retrieve Waste, and (3) Disposition Excess Facilities.

Download or read book Atomic Days written by Joshua Frank and published by Haymarket Books. This book was released on 2022-10-11 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: Once home to the United States's largest plutonium production site, the Hanford Nuclear Reservation in Washington state is laced with 56 million gallons of radioactive waste. The threat of an explosive accident at Hanford is all too real—an event that could be more catastrophic than Chernobyl. The EPA designated Hanford the most toxic place in America; it is also the most expensive environmental clean-up job the world has ever seen, with a $677 billion price tag that keeps growing. Huge underground tanks, well past their life expectancy and full of boiling radioactive gunk, are leaking, infecting groundwater supplies and threatening the Columbia River. Whistleblowers, worried that the worst is ahead, are now speaking out, begging to be heard and hoping their pleas help bring attention to the dire situation at Hanford. Aside from a few feisty community groups and handful of Indigenous activists, there is very little public scrutiny of the clean-up process, which is managed by the Department of Energy and carried out by contractors with shoddy track records, like Bechtel. In the context of renewed support for atomic power as a means of combating climate change, Atomic Days provides a much-needed refutation of the myths of nuclear technology—from weapons to electricity—and shines a spotlight on the ravages of Hanford and its threat to communities, workers and the global environment.
Download or read book Hanford Site Single shell Tank Roadmap written by and published by . This book was released on 1991 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Hanford Site Single-Shell Tank Roadmap covers the near-term waste management activities to ensure safe interim storage of 140 million liters of waste. It also addresses the environmental restoration activities to close the 6 single-shell tank operable units, which include 149 single-shell tanks. These tanks were constructed starting in the 1940's. Sixty-six tanks have leaked or are assumed to be leaking. This Roadmap has highlighted the need for integrated planning and resource allocation. The June 1990 Five-Year Plan did not address the tank safety concerns that evolved since its publication. Potential impacts to Tri-Party Agreement milestones for characterization, stabilization and isolation, technology development/demonstration, and closure will be examined in greater detail to strengthen the technical decision basis and to minimize consequences. The Roadmap indicates the advantage of accelerating characterization programs, technology evaluations, and supplemental environmental impact statement preparation. Working with regulators and expanded public outreach programs are essential to successful completion of this activity.
