  • Summary

    Chapter 4 focuses on the problematic nature of Navajo uranium and coal development following the end of World War II. By not revealing the dangers involved and holding back information on the value of the resources, the U.S. government facilitated particularly destructive forms of development while failing to ensure the tribe received fair compensation. The current reliance of the Navajo Nation on extractive industries for jobs and government revenue can be traced, in part, to the inequities in bargaining position and legal authority over the land that surround the mining agreements approved by the tribe in the early part of the self-determination period.

  • The characteristics of a fast ignition heavy ion fusion (FIHIF) power plant are preliminarily evaluated. The reactor chamber consists of two sections: The upper smaller part is the microexplosion section proper; the lower bigger part is the condensation section, in which sprayed jets of coolant are injected. The first surface of the blanket is of generally accepted wetted porous design. The coolant is lithium-lead eutectic with an initial surface temperature of 820 K. The mass of the evaporated coolant just after the explosion is evaluated as 4 kg. Computation of neutronics results in blanket energy deposition with maximum density of the order of 108 J/m3 at the first wall. The heat conversion system consisting of three coolant loops provides a net efficiency of the FIHIF power plant of 0.37.
