  • Assembly of TSVs including mounting of actuators and assembly of counterweights, penstock equalization valve (PEV) lines, and 4-inch isolation valves for sealant placement
  • Installation of new penstock piping connections for emergency cooling water and fire water supply
  • Supply and installation of new service water, air vent, and drainage steel piping
  • Stainless steel hydraulic tubing
  • Miscellaneous steelwork
  • Concrete placement within old TSV operator pits with floor drains; including miscellaneous valves, piping materials, pipe supports, fasteners, gasket materials, etc.
