Glass strategy: Hanford’s enhanced waste glass program
The mission of the Department of Energy’s Office of River Protection (ORP) is to complete the safe cleanup of waste resulting from decades of nuclear weapons development. One of the most technologically challenging responsibilities is the safe disposition of approximately 56 million gallons of radioactive waste historically stored in 177 tanks at the Hanford Site in Washington state.
ORP has a clear incentive to reduce the overall mission duration and cost. One pathway is to develop and deploy innovative technical solutions that can advance baseline flow sheets toward higher efficiency operations while reducing identified risks without compromising safety. Vitrification is the baseline process that will convert both high-level and low-level radioactive waste at Hanford into a stable glass waste form for long-term storage and disposal.
Although vitrification is a mature technology, there are key areas where technology can further reduce operational risks, advance baseline processes to maximize waste throughput, and provide the underpinning to enhance operational flexibility; all steps in reducing mission duration and cost.

This paper reports the results of in situ cable testing performed at the Oyster Creek Nuclear Generating Station in September 2016 to assess the aging condition of a number of cables as installed in the plant. Despite having been in service for over 40 years, our results found that these cables still met their qualification criteria, were in good working condition, and could continue to serve the plant for the foreseeable future. Some degradation in the cable insulation was noted but not as much as one would expect after more than 40 years of service in a nuclear power plant. Specifically, test results revealed that 10% of cables exhibited a noticeable degree of degradation, 30% were only slightly degraded, and the remaining 60% were essentially unaffected by aging. In the case of jacketed cables, which were assessed using walkdowns performed by the plant’s personnel, almost all aging and degradation were limited to the jacket material while the underlying cable insulation was largely unaffected. This is consistent with laboratory test results, which have shown that jacket material, especially Neoprene and Hypalon, degrade much faster than cross-linked polyethylene (XLPE) and other materials that are used for primary cable insulation.
