The solubility of helium and argon in liquid lead, bismuth, and their eutectic alloy at high temperatures

The “hole” model is used to calculate the solubility of inert gases of helium and argon, in heavy liquid-metal coolants of fast nuclear power reactors, such as lead, bismuth, and lead-bismuth eutectic, at temperatures up to $1000$ K and pressure of $0.1$ MPa. The relative error of the resultant calculation data is estimated.
