THE HIGH-YIELD LITHIUM-INJECTION FUSION-ENERGY (HYLIFE)-II INERTIAL FUSION ENERGY (IFE) POWER-PLANT CONCEPT AND IMPLICATIONS FOR IFE

In the High-Yield Lithium-Injection Fusion-Energy (HYLIFE) ppwer plant design, lithium is replaced by molten salt. HYLIFE-II [Fusion Technol. 25, 5 (1994)] is based on nonflammable, renewabie-liquid-wall fusion target chambers formed with Li2BeF4 molten-salt jets, a heavy-ion driver, and single-sided illumination of indirect-drive targets. Building fusion chambers from existing materials with life-of-plant structural walls behind the liquid walls, while still meeting non-nuclear grade construction and low-level waste requirements, has profound implications for inertial fusion energy (JFE) development. Fluid-flow work and computational fluid dynamics predict chamber clearing adequate for 6 Hz pulse rates. Predicted electricity cost is reduced about 30% to 4.4⊄/kWh at 1 GWe and 3.2⊄/kWh at 2 GWe. Development can be foreshortened and cost reduced by obviating expensive neutron sources to develop first-wall materials. The driver and chamber can be upgraded in stages, avoiding separate and sequential facilities, important features of a practical IFE power plant are ignition and sufficient gain in targets; low-cost, efficient, rep-ratable driver; and low-cost targets. © 1995 American Institute of Physics.
