The Chernobyl NPP has begun transportation of spent nuclear fuel from the wet storage (ISF-1) to the dry storage (ISF-2), the press service of the State Agency for the Management of the Exclusion Zone reports.

“Today, within hot tests, the first batch of nine spent fuel assemblies, which had been loaded the day before from the ISF-1 wet storage, was transported to the ISF-2 dry spent-fuel storage. The transportation of spent nuclear fuel takes place within separate permit for commissioning of a nuclear storage ISF-2, which was provided by the State Nuclear Regulatory Inspectorate of Ukraine,” the statement reads.

The commissioning of a dry storage facility will make it possible to reliably store spent nuclear fuel from the Chernobyl NPP for the next 100 years.

To Volodymyr Peskov, ChNPP Acting General Director, the beginning of the hot tests was preceded by many long-term preparations both at ISF-1 and ISF-2.

Transportation is carried out by a special container car, which additionally performs the function of protecting personnel from radiation exposure. It will take about ten years to transport all the spent nuclear fuel, which is now stored in the ISF-1.

“All operations carried out in ISF-2 are of a new-type, and handling of spent fuel assemblies at the new storage facility is quite complicated and includes cutting, repackaging, drying, sealing in a special case with further horizontal placement in a dry concrete storage module,” the message reads.
