A former senior manager for a federal energy agency has admitted that the Chinese government paid him for nuclear technological information while working for the utility, court records unsealed Friday show. Ching Ning Guey has struck a deal to plead guilty to a charge of development of special nuclear material outside the U.S. The case, kept under seal for more than a year, is tied to an indictment announced earlier this month against a Chinese nuclear engineer and a Chinese-owned nuclear power plant alleging nuclear espionage.

Guey worked from 2010 to 2014 as a senior manager for the probabilistic risk assessment division of the Tennessee Valley Authority. Guey had access through his job to tightly controlled information about the development and production of special nuclear material, according to a plea agreement filed by Assistant U.S. Attorney Charles Atchley.
