Most nuclear power plants<\/strong> operate a single-shaft turbine-generator<\/strong> that consists of one multi-stage HP turbine<\/strong> and three parallel multi-stage LP turbines<\/strong>, the main generator and an exciter. HP Turbine<\/strong> is usually a double-flow impulse turbine (or reaction type) with about 10 stages with shrouded blades and produces about 30-40% of the gross power output of the power plant unit. LP turbines<\/strong> are usually double-flow reaction turbines with about 5-8 stages (with shrouded blades and free-standing blades of the last 3 stages). LP turbines produce approximately 60-70% of the gross power output of the power plant unit. Each turbine rotor is mounted on two bearings, i.e., there are double bearings between each turbine module.<\/p><\/div><\/div>
