The solubility of Helium in lead-lithium eutectic alloy

چکیده
The helium production rates in liquid metals (Pb-Li eutectic alloy, LLE and others) Blanket Breeders (BB) are nearly mol-to-mol linked to tritium intimately associated with the compulsory requirement of high self-sufficiency next fusion reactors. When is oversaturated solubility limit exceeded, atoms can nucleate form bubbles. presence bubbles within channels could have severe impact on diverse BB designs, particular transport permeation its recovery. Even though He an inert gas assumed be insoluble, Henry’s constant (KH) a metal not zero. very low KH difficulties measure it has historically driven absence basic data. A semi-empirical correlation proposed providing (i.e.: constant) based Kumar’s cohesion model using available thermo-physical experimental data for lithium, sodium, potassium, mercury. expression lead–lithium is: KHat.fr.Pa-1=5.99·10-4exp(-1.16·δk)exp-54.23/RT, being constant; T [K], R [8.314 10-3 kJ mol−1 K−1] δk cohesive parameter. From justified value 18.2 MPa1/2 values range from 1.14·10-17 1.35·10 -15 at.fr.Pa−1 temperatures between 350 870C. should integrate nuclear material database systems design.

Critical temperature of the lead–bismuth eutectic (LBE) alloy
Liquid metals such as Bi and Pb and Pb–Bi eutectic alloy are serious contenders for use as coolant in LMFBRs in lieu of sodium due to a number of attractive characteristics (high density, low moderation, low neutron absorption and activation, high boiling point and poor interaction with water and air, etc.). Analysis of hypothetical accidents is of relevance to predict the catastrophe involving...
متن کاملOxygen-iron interaction in liquid lead-bismuth eutectic alloy.
Iron released by steel corrosion was found to be a key impurity in reactions with dissolved oxygen in liquid lead-bismuth eutectic alloys. The iron-oxygen-magnetite equilibrium was characterized, allowing the quantification of phenomena that are important for long-term operation of lead-alloy based installations such as corrosion rate control and management of precipitates.

3.2 Enthalpies, entropies (solid and liquid state) – free energy and entropy of mixing The heats of formation of six solid Pb-Bi alloys have been measured at 400 K in a liquid lead solution calorimeter by P. Roy, et al. They found that these alloys obey Kopp’s law of additivity and the heats of formation are therefore temperature independent. The lead and bismuth used in these experiments were ...
متن کاملCavity mediated strain localization and overall ductility in eutectic tin-lead alloy
A combined experimental and numerical study is undertaken to examine the effects of pre-machined holes on strain localization and overall ductility in eutectic tin-lead alloy. Thin-sheet specimens with equal-sized holes aligned in the tensile loading direction are used. The tensile tests were performed at room temperature with a nominal strain rate of 0.001 s . The specimen, containing one hole...
