LOTUS 2.0 (MFC-1765) is the next development phase of the Laboratory for Operation and Testing in the United States. LOTUS 2.0 will be designed and constructed at the current location of MFC-1727. MFC-1727 will be excessed or disposed of in the CFA landfill. The objective is to design and construct a flexible, secure, and general-purpose research facility to support advanced reactor experiments up to a steady state power of 500 kWt that will utilize Safeguards Category I materials. LOTUS 2.0 will feature a large, flexible Experiment Area (EA) and supporting spaces, and shall meet NDC-3 structural requirements to ensure resilience and enable potential future nuclear applications.
