Chornobyl NPP has started transportation of spent nuclear fuel from Interim Storage Facility for Spent Fuel (ISF-1) and Interim Spent Nuclear Fuel Dry Storage Facility (ISF-2)

On September 10, as part of «hot» tests the first batch of 9 spent fuel assemblages was transported to the Spent Nuclear Fuel Dry Storage Facility of the «dry» type ISF‑2 which was loaded the day before from the «wet» type ISF-1 Storage Facility for Spent Fuel.

The transportation of spent nuclear fuel takes place within the framework of a separate permit for the commissioning of a nuclear installation - Spent Nuclear Fuel Storage Facility (ISF-2) which was provided by the State Nuclear Regulatory Inspectorate.

«The start of «hot» tests and transportation of spent nuclear fuel to ISF-2 is an important event that was expected not only by Ukraine, but also by our international partners who support our country during the decommissioning of the Chornobyl nuclear power plant and transformation The Shelter Object into environmentally friendly system. I would like to thank once again all the relevant Ukrainian institutions for their efficient and coordinated work, the donors of the Nuclear Safety Account of the European Bank for Reconstruction and Development for financial support and the contractors who worked in quarantine conditions. I wish the staff of the Chornobyl NPP a successful and, most importantly, safe conduct of «hot» tests», - said the Minister of Environmental Protection and Natural Resources of Ukraine Roman Abramovskyi.

The Minister also added that security is the most important aspect that must be observed during any activity. And the commissioning of the «dry» type will allow to safely store spent nuclear fuel of the Chornobyl nuclear power plant for the next 100 years.

As noted by Volodymyr Peskov, Acting General Director of ChNPP the beginning of the «hot» tests was preceded by long preparatory work on both ISF-1 and ISF-2. The management of spent nuclear fuel in both storage facilities and its transportation is a set of rather serious interconnected operations, and the «hot» tests themselves are an important technological process that will now be performed with real spent assemblages, not their simulators.

Transportation is carried out by a special container car which additionally performs the function of biological protection of personnel from radiation exposure. It takes about ten years to transport all the spent nuclear fuel which is now stored in the «wet» type ISF-1 Storage Facility.

All operations carried out in ISF-2 are new, and the handling of fuel assemblages directly at the new storage is quite complex and includes cutting, repacking, drying, pressurization in a special case and further horizontal placement in a dry concrete module for storage.
