The Hanford Site in Washington state stores millions of gallons of high-level radioactive waste in 28 double-shell tanks. The tanks are buried underground to enhance radiation shielding. The space between the primary tank and the steel liner can be used to allow inspection of the inaccessible regions of these vessels.Nuclear power plant containment vessels have large, inaccessible regions that cannot be inspected by conventional techniques. Inaccessible regions often are encased in concrete, soil or sand, or hidden behind equipment attached to a wall. Similar constraints affect the inspection of double-shell tanks designed to store nuclear waste, illustrated in Figure 1, that have an inaccessible region at the tank bottom where the primary shell is supported by the secondary shell. Present methods to monitor the integrity of these vessels primarily rely on partial inspections of accessible areas or estimation of corrosion rates; however, these approaches cannot account for nonuniform localized corrosion or cracking.Go to ArticleShare:LinkedInTwitterFacebook
Sponsored ContentI&C vendor insights: safety digital technology selection to win the energy marketNuclear NewsRadICSRadICS-based RPS-ESFAS systemCommercial nuclear power plants in the United States (U.S.) face tough competition from sources of alternative generation (e.g., solar, wind, etc.), cheap natural gas, especially in the unregulated market. It is recognized that 35 percent of the U.S. nuclear power plants, representing 22 percent of U.S. nuclear capacity, are at risk of early closure due to economic factors. Plant operators have been reluctant to adopt modern digital technologies for safety-related systems even though these technologies offer many benefits to improve safety and reliability, as well as achieve operating cost reductions.Go to ArticleShare:LinkedInTwitterFacebook

Sponsored ContentA simple, revolutionary approach to waste packagingNuclear NewsWaste ManagementCentral Research LaboratoriesBy Rob Weber, Projects and Proposals Manager, Central Research LaboratoriesAddressing Current ProblemsBag-out operations can pose many issues to the TRU waste handling and disposal process. Among these are operator and facility safety, operational time, excess waste volume, and increased shipping costs to a waste repository.Historically, removing hazardous waste from gloveboxes has involved using bags for primary containment. This bag-out method can prove tedious, repetitive, and time-consuming to ensure it follows all required safeguards to transfer waste without breaching containment. Layers of bags, yards of tape, and multiple filters are all added to the waste stream to transfer hazardous waste safely from the glovebox into a disposal drum.Go to ArticleTags:central research labsdisposalwasteShare:LinkedInTwitterFacebook
