A fast reactor initially loaded with a mixed oxide fuel with the composition of $U_{0\mathrm{.}85}P{u}_{0\mathrm{.}15}{O}_{1\mathrm{.}96}.$

Design burnup for this fuel is $8\%.$ Calculate the composition of metallic inclusions for a

specified point in the fuel characterized with the temperature of $2300K.($Hint: Consider

thermodynamical equilibrium and also charge balance$)$

$G_{\frac{M}{o}O}=-574+164(\frac{T}{{10}^3})k\frac{J}{m}$ole
