X-energy raises $700M in latest funding round
Advanced reactor developer X-energy has announced that it has closed an oversubscribed Series D financing round of approximately $700 million. The funding proceeds are expected to be used to help continue the expansion of its supply chain and the commercial pipeline for its Xe-100 advanced small modular reactor and TRISO-X fuel, according the company.

NAÏADE 1 shielding experiments were performed in the shielding laboratory at the Commissariat à l'Energie Atomique (French Atomic Energy Commission) in Fontenay aux Roses during the period 1965-1970. These experiments consisted of studying either the pure thermal neutron attenuation or the fission neutron attenuation in various materials such as water, iron, graphite, concrete, and multilayer shields. A reassessment of the experimental results was made between 2003 and 2005, and the results were evaluated again during the period 2007-2008. For each experimental configuration, the fission neutron source of a converter was calculated by using the TRIdimensionel POLYcinétique (TRIPOLI-4) Monte Carlo code. A part of the experimental results has been compared to the results of TRIPOLI-4. This work will be continued to analyze other benchmarks with integration into the Shielding INtegral Benchmark Archive Database (SINBAD).
