From September 30th to October 4th, the relevant departments of the central environmental impact assessment department and the Ministry of waste disposal went to Czech to participate in the International Atomic Energy Agency (IAEA) technical cooperation project.

The visit was mainly carried out among the uranium mines and research institutes owned by DIAMO, a state-owned enterprise in Czech. They visited the water treatment facilities of Pribram uranium mine, the Pribram uranium Museum, the National Laboratory of nuclear, chemical and biological protection and related laboratories, the underground laboratory of the rhodna uranium mine and the hydrometallurgy plant of dnroxinka, Caim. In situ leaching and related groundwater separation and treatment projects.

With the end of the Second World War and the cold war between the Soviet Union and the United States, extensive uranium mining activities came to a close in Czech, instead of a large amount of time and money needed to repair the environment. According to the introduction, deemmer applies to the government every year for the budget, mainly used to control the groundwater pollution and environmental problems caused by the early uranium mining. It is estimated that the groundwater treatment cost of a single leaching uranium mine (about 27km2) is about 18 billion yuan, and is expected to take 30 years to complete. Experts from deemer also introduced their experience in environmental remediation and site remediation.

Central personnel visited the UAV detection, underground laboratory nuclide migration settings, environmental remediation technology and equipment and other content exchange, the Czech's attention on the retired regulations, requirements of the regulatory system, retired management funds management mechanism and underground laboratory research projects and environmental monitoring of tailings and other content with deemer staff in-depth discussions.

This visit will provide engineering experience for the decommissioning of nuclear facilities in China, and provide reference for the subsequent development and revision of the regulations and standards for decommissioning of nuclear facilities.
