    Increasing critical heat flows in VVER-1000 model fuel assemblies by inserting additional spacing lattices

    One way to increase the margin to critical heat transfer is investigated – closer lattice spacing on the axial section of a fuel assembly with the minimum margin to critical heat emission. Experiments were per...
