Radiant to build first microreactor at Tenn. Manhattan Project site
Radiant Industries will build its first portable nuclear reactor at the site of the Manhattan Project in Oak Ridge, Tenn.
The land for Radiant’s new factory includes portions of the K-27 and K-29 Manhattan Project sites. The company plans to test Kaleidos, a 1-MW nuclear microreactor, in 2026, with first deployments expected soon after.

This work shows that summary statistics for fixed-source Monte Carlo problems sampled by batch are subject to more variability than are statistics sampled by individual histories. This is most pronounced when the number of batches used is small. Using individual histories, or a larger number of smaller batches, allows for better precision in estimating the variability of the underlying quantity being calculated when the histories are uncorrelated.
