US-based Holtec International has completed the production and acceptance tests for 20 HI-Storm casks and one multi-purpose MPC-31 canister for spent nuclear fuel from VVER-1000 reactors in Ukraine, state-owned nuclear operator Energoatom said.The equipment will be used at Ukraine’s national centralised storage facility for spent nuclear fuel located in the Chernobyl exclusion zone, Energoatom said.The Ukrainian company said the equipment batch comprises the second phase of a contract between Energoatom and Holtec, which was signed in 2005, but whose implementation was delayed because of “political reasons” among others.
