The first ever HI-STORM FW (Flood & Wind) cask loading campaign came to a successful conclusion on October 23, 2015 at Tennessee Valley Authority’s (TVA) Browns Ferry nuclear plant when the 12th cask was safely placed in long term storage on the Independent Spent Fuel Storage Installation (ISFSI) pad. The loading of the MPC-89 multi-purpose canister (MPC) marked the first use of the world’s highest capacity and heat load canister for a BWR site storing 89 BWR assemblies. A total of 1,068 spent fuel assemblies were placed into dry storage during this evolution, setting the record for the highest number of fuel assemblies ever loaded in a single loading campaign at an operating reactor site. As a result, Browns Ferry removed a total of 342.49 kW from its three spent fuel pools, as part of its efforts to manage the spent fuel pool temperatures. Most importantly, all twelve (12) canisters were loaded safely, with zero incidents, and ahead of schedule. Holtec’s site services team, with superb support from TVA, showed significant improvements in dose performance throughout the campaign by focusing on ALARA (As Low As Reasonably Achievable) principles, resulting in 6.5 mRem of accumulated crew dose per assembly on the final cask. |
