Idaho National Laboratory Lead or Lead-Bismuth Eutectic (LBE) Test Facility - R&D Requirements, Design Criteria, Design Concept, and Concept Guidance

Abstract

SUMMARYThe Idaho National Laboratory Lead-Bismuth Eutectic Test Facility will advance the state of nuclear technology relative to heavy-metal coolants (primarily Pb and Pb-Bi), thereby allowing the U.S. to maintain the pre-eminent position in overseas markets and a future domestic market. The end results will be a better qualitative understanding and quantitative measure of the thermal physics and chemistry conditions in the molten metal systems for varied flow conditions (single and multiphase), flow regime transitions, heat input methods, pumping requirements for varied conditions and geometries, and corrosion performance. Furthering INL knowledge in these areas is crucial to sustaining a competitive global position.This fundamental heavy-metal research supports the National Energy Policy Development Group's stated need for energy systems to support electrical generation.

The Choice of Coolants in Accelerate Driven System

“…The outlet temperature changes with the pipe length of the different secondary coolant could be computed by formula (5). The coolant absorbs heat Q from the heat source when the temperature of the heat source is higher than the coolant, the maximum work made by the reversible heat engine is the heat exergy [10] .…”

“…Still, there are some experiment circuit choose low pressure water, for example XT-ADS and ICE [4] . The United States of America [5] carried out a lot study on ADS, most of them are focussed on the material test and device build. There are more and more scientific research institutions begin to research ADS, but the documents published about the secondary coolant in ADS are rarely seen.…”
