A conceptual design strategy for liquid-metal-wall inertial fusion reactors

Abstract

The liquid-metal-wall chamber has emerged as an attractive reactor concept for inertial fusion energy conversion. The principal feature of this concept is a thick, free-flowing blanket of liquid metal used to protect the structure of the reactor. The development and design of liquid-metal-wall charters over the past decade provides a basis for formulating a conceptual design strategy for such chapters. Both the attractive and unattractive fea tures of a DV chanter are enumerated, and a design strategy is fornulated which accomo dates the engineering constraints while crinimizing the liquid-aetal flow rate. !

Experimental Study on Condensation Heat Transfer on Surface of Liquid Jet

“…(; Re,K,Pr,p,p,J.,c 11 ) ' ' ' ( 2) which is based on the physical insight that the intensity of heat transfer is determined by turbulent thermal diffusion and surface disturbances. It has been found from the data that St increases with increasing Pv with all other variables being kept constant.…”

Experimental and numerical investigation of shock wave propagation through complex geometry, gas continuous, two-phase media

“…The jets are packed roughly in a hexagonal geometry, and the total blanket thickness, including the volume between jets is 1.6 meters. The required thickness is determined by the maximum neutron depositions per atom (dpa) that the vessel wall material can sustain during the 30 year reactor lifetime [Monsler and Meier, 1981]. The fall height from the orifice plate to the surface of the lithium pool at the bottom of the vessel is nominally 8…”
