STARTUP AND SHUTDOWN OF THE PULSAR TOKAMAK REACTOR

Startup conditions are examined for a pulsed tokamak reactor that uses only inductive plasma current drive for startup, burn and shutdown. A zero-dimensional (profile-averaged) model that describes plasma power and particle balance equations is used to study several aspects of pl asma startup and shutdown, including optimization of the startup pathw ay tradeoff of auxiliary startup heating power versus startup time, vo lt-second consumtion, thermal stability and partial-power operations.
