Ignalina NPP: One More Step Taken Toward the Start of Spent Nuclear Fuel Discharge

Января 25, 2016

The Ignalina Nuclear Power Plant (INPP) commenced another important stage in implementation of project B1 (Interim Spent Nuclear Fuel Storage Facility, ISFSF): cold trials of the equipment for handling of spent nuclear fuel at Units.

Cold trials are tests whereon all future actions on operation are rehearsed without the use of radioactive material. Full functioning, intercompatibility of the equipment and its compliance with the design documents are checked in order to approve the ISFSF conformity with the requirements of the normative documents of the Republic of Lithuania.  

The Cold Trials Programme was agreed with the State Nuclear Power Safety Inspectorate (VATESI).

The modified crane and one of the casks for spent nuclear fuel storage will be used for the trials implementation.

“The following actions with the cask will be performed without the use of radioactive waste: cask transfer to the service station in the Storage Pools Hall, cask preparation for loading, dummy fuel loading to the cask, cask sealing, cask leakage test and preparation for transportation to the storage facility,” said Director of INPP Decommissioning Department Sergej Krutovcov.

The completion of cold trials at the Units is planned for end of June.

Successful completion of the cold trials at the Units is one of the conditions to obtain VATESI license for the ISFSF operation, which would allow starting preparation for the final stage of the project, i.e. hot trials (using spent nuclear fuel).

The completion of hot trials is planned in summer 2017 followed by start of ISFSF industrial operation in autumn 2017.

Project B1 is financially supported by the Ignalina International Decommissioning Support Fund (IIDSF) managed by the European Bank for Reconstruction and Development. Assembly of Contributors governing IIDSF consists of European Commission, Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Luxembourg, Netherlands, Norway, Poland, Spain, United Kingdom, Sweden and Switzerland.
