 Recent Projects: MCE projects for commercial and quality levels:
Composed of six large components, the M3 Mixing Test Platform is 36 feet long, 24 feet wide and stands more than 12 feet tall fully assembled. When operational, the WTP will use PJMs to mix the waste being processed through the Pretreatment (PT) Facility and High-Level Waste (HLW) Vitrification Facility. Mixing is essential to the waste treatment process to ensure the movement of waste from vessel to vessel and to prevent solids from settling to the bottom of the vessels. The M3 Mixing Test Platform will be used to confirm the effectiveness of pulse jet mixers (PJMs), an essential waste mixing technology that will be used to process tank waste for treatment in the WTP at the U.S Department of Energy's (DOE) Hanford Site in southeastern Washington State. The M3 Mixing Test Platform is being built in response to a comprehensive independent review of WTP conducted by the External Flowsheet Review Team (EFRT) in 2006. The team was composed of fifty experts from national laboratories, universities, the nuclear waste complex, the chemical processing industry and the glass industry, including members from the National Academy of Engineers and the National Academy of Science. The EFRT recognized the operability of the PJMs but felt further confirmatory testing was needed to ensure the PJMs provided the necessary mixing for the WTP. The platform testing being conducted by the Energy Solutions/NuVision Engineering/MCE team will resolve one of the last technical issues identified. The work involves designing, building and testing of mixing systems under prototypic configurations that represent the actual deployment of some of the Waste Treatment Project process vessels. |
