41. One promising alternative from this perspective is an accelerator-driven sub-critical reactor / subcritical reactor. 42. Related to the critical flow demarcation between subcritical flow and supercritical flow ( see also Froude number ). 43. Subcritical flow has a larger potential energy component, and supercritical flow has a larger kinetic energy component.44. This created a transition from subcritical flow conditions to supercritical flow conditions through the throat of the flume. 45. The DOE has not demonstrated that it cannot maintain the safety of the existing nuclear arsenal without subcritical experiments. 46. Over the past year, the " subcritical " experiments have increased employment and income a bit. 47. In related work, Kauffman and colleagues have examined subcritical , critical, and supracritical behavior in economic systems. 48. When the flow is subcritical , defined by a Froude number less than 1, the reach is mild. 49. Once the reach approaches subcritical conditions, with a Froude number less than one, the discharge gradually decreases. 50. These blocks help induce a hydraulic jump to establish subcritical flow conditions on the downstream side of the dam.
