A pulsed fusion reactor potentially influences many commercial plant design provisions. Provisions related to turbine fatigue performance are among those considered important. They are evaluated by varying several design/operating parameters, separately and in combination, to present tradeoffs among them. These parameters include pulse length and capacity of the thermal storage system. A very simple and fast running temperature/stress representation of the turbine is used for evaluations. Results for wet-steam turbines indicate that requirements for thermal storage are quite large (steam flow between 40 and 80% of full steam flow). Modeling assumptions, design options, and important operating considerations are highlighted.
