New research published in PNAS Nexus reveals that Nazi Germany's WWII nuclear program lacked sufficient uranium and heavy water to achieve criticality in their B8 pile reactor, contradicting Werner Heisenberg's later claims. The study was partly inspired by Timothy Koeth's discovery of one of only 14 known surviving uranium cubes used by German scientists, which he received as a mysterious gift in 2013.
Background
During WWII, Allied physicists feared Nazi Germany would develop nuclear weapons first. The German nuclear program, led by Werner Heisenberg, ultimately failed, but historians have long debated whether it was due to scientific error, sabotage, or insufficient resources. This research provides new empirical evidence on the resource constraints.
