A radial flow reaction turbine is a turbine that uses water pressure to run a generator at high speed and produce electricity. 

Here's some information about radial flow reaction turbines:
In a radial flow turbine, the working fluid flows radially relative to the shaft.
The fluid enters the turbine near the center of the rotor and flows outward towards the periphery.
The curved blades deflect the fluid, causing it to change direction and imparting a force on the blades that causes them to rotate.
The area of spiral structure gradually decreases because as discharge decreases correspondingly area also decreases. So, runner will rotate with constant velocity.
 

Guide vanes are placed around the runner to regulate the flow and to provide shock less entry at inlet to runner.
Radial-flow turbines have very high energy extraction capability in one single stage.

There are two types of inward-flow radial turbines: the cantilever and the mixed-flow types.
The radial-inflow turbine, or inward-flow radial turbine, is used for smaller loads and over a smaller operational range than the axial turbine.
The Francis turbine is a radial inward flow turbine and is the most popularly used one in the medium head range of 60 to 300 m.
