We discuss a high-density fusion reactor which utilizes a flow-through
Z pinch magnetic confinement configuration. Assessment of this reacto
r system is motivated by simplicity and small unit size (few hundred M
We) and immunity to plasma contamination made possible at high density
. The type reactor discussed here would employ a liquid Li vortex as t
he first wall/blanket to capture fusion neutrons with minimum induced
radioactivity and to achieve high wall loading and a power density of
200 w/cm(3).
