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.

Plutonium-238 in contaminated trash and equipment contained in steel drums was determined by measuring, with a Nal(Tl) detector, the intensity of the 765-keV gamma ray from the decay of 238Pu. By gamma-ray stripping, the contributions of higher energy gamma rays to the 76S-keV gamma-ray photoelectric peak could be subtracted, despite the large amount of scattering material present in the drum. The transmission of the 765-keV gamma ray inside the drum was determined by measuring the transmission through the drum of the 765-keV gamma ray from external 238Pu standard sources. The uncertainty in the measurements is ±28% at the 95% confidence level when the drum contains ≥0.180 g of 238Pu.
