The main activities of Everclean Environmental Engineering Corporation (EEEC) include the transportation, storage, treatment, and disposal of radioactive waste from nuclear power plants.[1]

Along with the China Nuclear Energy Industry Corporation (CNEIC) and Guangdong Nuclear Power Joint Venture Company (GNPJVC), EEEC was part of a joint venture responsible for the transportation of spent fuel casks from the Guangdong Daya Bay Power Plant in Guangdong province to the Lanzhou Nuclear Fuel Complex in Gansu province, a distance of roughly 4,000 km.[2] The Lanzhou Nuclear Fuel Complex is the site of a centralized waste storage facility and pilot-scale commercial reprocessing plant. In 2009, Everclean Corporation was criticized by China’s National Nuclear Safety Administration (NNSA) after an audit found that the company changed the route for the transportation of Guangdong Daya Bay spent nuclear fuel without proper authorization or adequate analysis of the possible consequences.[3]
