TVA’s Sequoyah nuclear powerplant needs a new generator. This is going to result in one of the largest cargos to be loaded on a barge floating upstream on the Tennessee River through the locks at TVA’s Chickamauga Dam.
Due to a mistake made back when the lock and dam was built back in the late ’30s we’ve got a reaction going on between the concrete and the aggregate used to build the lock which means it is constantly being repaired. Year after year we hear about more funds being approved for repair to the lock. The lock really needs to be replaced.
