Abstract
A power plant including a steam turbine, and a steam turbine exhaust duct configured to deliver uncontaminated fluid from the steam turbine to downstream components of the power plant. The steam turbine exhaust duct includes a steam turbine exhaust duct isolation valve selectively configured to prevent fluid communication between the steam turbine exhaust duct and the downstream components of the power plant, and a steam turbine exhaust duct vent with a steam turbine exhaust duct vent valve. The steam turbine exhaust duct vent is configured to deliver contaminated fluid from the steam turbine exhaust duct to a fluid sink upon opening of the exhaust duct vent valve.
