Deep Fission to break ground this week
With about seven months left in the race to bring DOE-authorized test reactors on line by July 4, 2026, via the Reactor Pilot Program, Deep Fission has announced that it will break ground on its associated project on December 9 in Parsons, Kansas. It’s one of many companies in the program that has made significant headway in recent months.

This work presents the results of measurements of the effective thermal conductivity of Li2O and Be pebble beds using a hot wire method1. Also, preliminary results for a binary bed using Al2O3 pebbles are presented. The measured value for an Al2O3 single packing bed showed good agreement with Schulunder's correlation2 and Hall-Martin's correlation3 with a contact area fraction of 5 × 10−5. The value of the contact area fraction in this study showed consistency with that reported by Dalle Donne et al.4. Results for the binary bed of Al2O3 (0.3 mm and 3 mm) pebbles showed good agreement with the same correlation using the same value of contact area fraction. The measured value of the effective thermal conductivity for an Li2O bed using 1 mm pebbles agreed with the correlation using a value of 4.9 × 10−3 for the contact area fraction. The measured values of the effective thermal conductivity for 0.6 mm and 1mm Be pebble beds showed consistency with the correlation using 1 × 10−4 for the contact area fraction.
