Division Spotlight
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

TerraPower begins U.K. regulatory approval process
Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.
TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.

Apparent excess heat is observed in light water electrolytic cells containing a variety of nickel cathodes, a platinum anode, and an electrolyte of K2CO3 in H2O. High-accuracy calorimetric measurements show apparent excess heat in the range of 15 to 37% of input power if a 100% Faraday efficiency is assumed for H2 and O2 gas release. The H2 and O2 gases released during electrolysis are recombined in a vessel external to the cell, and the quantity of recombined H2O is compared with the quantity of H2O expected from 100% efficient electrolysis. The measured Faraday efficiency is shown to be significantly <100%, and conventional chemistry can account for the entire amount of observed apparent excess heat to within an accuracy of better than 0.5%.
