When new information is learned, an ethical duty exists to analyze previous assumptions and update our understanding. As nuclear systems can be catastrophic if miscalculated, it is crucial to account for all safety aspects including the computers running the machines and the thermodynamic limitations of the universe.A literature review reveals no published Landauer analysis (E ≥ kBT ln(2)) applied to nuclear reactor control systems. The physics capabilities of the computers controlling these reactors have never been analyzed against the capabilities being promised. With the connection of information-mass-energy equivalency m(T) = kBT ln(2)/c², a review of all technology and their energy-consuming counterparts must be performed, and behaviors adjusted based on the new understandings revealed.The Infoton Landauer safety report demystifies the complexity of Quantum Information Science and Nuclear Energy for the everyday reader with a line-by-line breakdown of the math and full explanations. The analysis covers fusion and fission nuclear systems, plasma thermodynamics, environmental impacts, resource and rare earth dependencies, computational requirements, and verifiability of claims from the energy industry.
