  • The report summarizes the findings of a U.S. Department of Energy workshop on “Corrosion Issues of Relevance to the Yucca Mountain Waste Repository”. The workshop was held on July 29-30, 2003 in Bethesda, MD, and was co-sponsored by the Office of Basic Energy Sciences and Office of Civilian Radioactive Waste Management. The workshop focus was corrosion science relevant to long-term prediction of materials performance in hostile environments, with special focus on relevance to the permanent disposal of nuclear waste at the Yucca Mountain Repository. The culmination of the workshop is this report that identifies both generic and Yucca Mountain Project-specificmore » research opportunities in basic and applied topic areas. The research opportunities would be realized well after the U.S. Nuclear Regulatory Commission’s initial construction-authorization licensing process. At the workshop, twenty-three invited scientists deliberated on basic and applied science opportunities in corrosion science relevant to long-term prediction of damage accumulation by corrosive processes that affect materials performance.« less
  • Two of the most widely used corrosion protection systems for steel in reinforced concrete are epoxy-coated steel and calcium nitrite. In severe exposures to deicing or marine environments engineers often require more than one protection system, referred to as a ``Belts and Suspenders`` approach. In this work the performances of calcium nitrite and epoxy-coated reinforcing bars in combination and alone are documented after several years of accelerated testing in good quality concretes. The data show that calcium nitrite definitely improves the performance of epoxy-coated reinforcing bars, even when they are severely damaged as might occur due to poor handling ormore » concrete placement. Undamaged epoxy-coated reinforcing bars had similar performance to calcium nitrite and the combination system was an improvement.« less

  • Performance assessment calculations are required for high level waste repositories for a period of 10,000 years. The Siting Guidelines require a comparison of sites following site characterization and prior to final site selection to be made over a 100,000 year period. To perform the required calculations, a detailed knowledge of the physical and chemical processes that affect waste form performance will be needed for each site. This paper will review the factors that affect the release of radionuclides from spent fuel under repository conditions, summarize our present state of knowledge, and suggest areas where more work is needed to supportmore » the performance assessment calculations. 17 refs., 5 figs., 3 tabs.« less
