Project Pele is a mobile microreactor program using a two-phased approach to mitigate project and technical risk. Phase I is design and Phase II is construction. In Phase I (approximately 24 months), Department of Defense (DoD) intends to award multiple prime contracts. At the conclusion of Phase I, there will be a non-competitive down selection process to identify the team(s) for Phase II (approximately 24 months). Phase I awardees will work to develop a prototype design for a mobile microreactor and will produce programmatic design-to-build and risk reduction plans before a successive Phase II award.
