Heating of the first waste vitrification melter at the Department of Energy’s Hanford Site was paused after operators identified an “abnormal condition with the startup heater power supplies,” the DOE’s Office of River Protection (ORP) said. Heat-up of the 300-ton melter, which will be used to vitrify Hanford’s low-level radioactive tank waste, was initiated on October 8.

As the Department of Energy's Hanford Site prepares for around-the-clock operations for tank waste disposal, workers at the site's 242-A Evaporator are upgrading equipment used to remove water from the tank waste and the systems that transfer waste to and from large underground containers. The upgrades will also extend the evaporator’s service life.
