The short answer

Lazar states 223 grams of element 115 were needed as reactor fuel and names three specific project codenames (Galileo, Sidekick, Looking Glass) run out of S-4. Element 115 (moscovium) is a real but entirely synthetic superheavy element, first produced via nuclear fusion reactions in a Dubna/JINR-Oak Ridge-Livermore collaboration and formally named in 2016; per Oak Ridge National Laboratory, it has only ever been generated one atom at a time, arising as a decay product of element 117 in accelerator experiments, not synthesized or isolated directly in bulk.

// THE CLAIM · ON TAPE
In fact, you need 223 grams machined into a wedge like this. The program out at S-4 consisted of three projects, Project Galileo, Project Sidekick, and Project Looking Glass.

What the evidence says 01 / RECORD

Lazar has claimed since 1989 that a 223-gram, stable sample of element 115 fueled a reactor at S-4, and that the site ran three projects he named Galileo, Sidekick, and Looking Glass. Element 115 (moscovium) is a real but entirely synthetic superheavy element, first produced via nuclear fusion reactions in a Dubna/JINR-Oak Ridge-Livermore collaboration and formally named in 2016; per Oak Ridge National Laboratory, it has only ever been generated one atom at a time, arising as a decay product of element 117 in accelerator experiments, not synthesized or isolated directly in bulk. Its most stable known isotope corresponds to an atomic weight of 289, matching the figure on Los Alamos National Laboratory's periodic table entry, whose listed physical properties are explicitly labeled as theoretical predictions rather than measurements, since no macroscopic quantity of the element has ever existed to measure. No stable, weighable quantity of element 115, let alone 223 grams, has ever been produced or documented by any laboratory. The Galileo, Sidekick, and Looking Glass project names, like the 223-gram figure, exist only in Lazar's own testimony and interviews going back to 1989; no government document, physicist, or S-4 colleague has ever independently corroborated them, and no verified record places Lazar in a physicist role at any such facility. The claim is unsupported by physical evidence and contradicted by the established properties of the real element it invokes.
