Vistra’s Perry nuclear plant approved for license renewal
Texas-based Vistra Corporation has announced that its license renewal application for the Perry nuclear power plant was approved by the Nuclear Regulatory Commission. The plant first connected to the grid in 1986 and is still operating under its original 40-year license, which was set to expire next year.

Design analyses and tradeoff studies for the bulk shield of the Tokamak Fusion Core Experiment (TFCX) were performed. Several shielding options were considered to lower the capital cost of the shielding system. Optimization analyses were carried out to reduce the nuclear responses in the TF coils and the dose equivalent in the reactor hall one day after shutdown. Two TFCX designs with different toroidal field (TF) coil configurations were considered during this work. The materials for the shield were selected based upon trade-off studies and the results from the previous design studies. The main shielding materials are water, concrete, and steel balls (Fe1422 or Nitronic 33). Small amounts of boron carbide and lead are employed to reduce activation, nuclear heating in the TF coils, and dose equivalent after shutdown.
