eVinci™ Microreactor

Westinghouse is currently developing the eVinci Microreactor, a next-generation, very small modular reactor for decentralized remote applications

The eVinci microreactor’s innovative design is a combination of space reactor technologies and 50+ years of commercial nuclear systems design, engineering and innovation. The eVinci microreactor aims to create competitive and resilient power with superior reliability and minimal maintenance, particularly for energy consumers in remote locations. Its small size allows for standard transportation methods and rapid, on-site deployment in contrast to large, centralized stations. The reactor core is designed to run for three or more years, eliminating the need for frequent refueling.

The key benefits of the eVinci microreactor are attributed to its solid core and advanced heat pipes. The heat pipes enable passive core heat extraction, allowing autonomous operation and inherent load following capabilities. These advanced technologies together make the eVinci™ microreactor a pseudo “solid-state” reactor with minimal moving parts.

eVinci™ Microreactor Mobile Nuclear Power Plant

While the eVinci microreactor design is transportable, the eVinci microreactor designed for government usage allows for mobile operations utilizing standard military transportation vehicles and containers. The nature of the design will allow the reactor to be rapidly transported to sites as needed to create an abundant and resilient power supply to support advanced defense systems.

Key Attributes of eVinci Microreactor:

  • Transportable energy generator
  • Fully factory built, fueled and assembled
  • Delivers combined heat and power – 5 MWe and up to 13MWt
  • 8+ years of full power operation prior to refueling
  • Target less than 30 days onsite installation
  • High speed load following capability
  • High reliability and minimal moving parts
  • Capable of autonomous operation
  • Near zero Emergency Planning Zone with small site footprint
  • No spent fuel or waste storage on site
  • Simplified decommissioning and remediation
