Three-region restructured fuel, with given thermal characteristics, may be represented by an effective conductivity integral function Y(T). For any fuel surface temperature Ts and linear heat generation rate q, the maximum fuel temperature Tv is found from the relation Yv - Ys = q. Region radii and molten fuel fraction appear in the groups qR2/R and qF as functions of Yv - Ye.
