Method can detect harmful salts forming in nuclear waste melters

A new way to identify salts in nuclear waste melters could help improve clean-up technology, including at the Hanford Site, one of the largest, most complex nuclear waste clean-up sites in the world. Researchers used two detectors to find thin layers of sulfate, chloride and fluoride salts during vitrification, a nuclear waste storage process that
