Staff Fluid Systems Engineer

At Radiant Systems Inc in the IT Staffing space, Global Software and Services Excellence Through Intellectual Capital and Innovation.

Radiant, a leader in portable, mass-produced nuclear microreactors, today announced that the U.S. Department of Energy (DOE) has granted approval of its DOE Authorization Request for Kaleidos (DARK). This documentation submitted by Radiant is designed to meet the intent of a Preliminary Documented Safety Analysis (PDSA), and approval allows Radiant to keep on track to start up its first reactor this summer. This approval, the first granted for a full-power test, closes out the second of three nuclear safety document submittals in DOE’s new Authorization Pathway for Nuclear Facilities, paving the way towards reactor startup at the National Reactor Innovation Center’s (NRIC) Demonstration of Microreactor Experiments (DOME) facility at Idaho National Laboratory (INL). Radiant’s Kaleidos microreactor is designed to deliver reliable power in mission-critical environments, supporting both national security and commercial energy resilience objectives. The DARK approval reflects close collaboration between Radiant, DOE, and INL to establish a repeatable, efficient regulatory model for advanced nuclear deployments. With this milestone complete, Radiant is now preparing for the final documented safety analysis submittal, and readiness review, leading to authorization and startup of its first reactor at INL this summer.
