摘要: Fuel assembly for a pressurized water nuclear reactor, comprising peripheral zone (1) consisting of first group rods (2) containing mainly enriched uranium oxide and central (4) second (5) plutonium or depleted in fissile uranium. The the are spaced sufficiently so that neutrons slowed down to thermal region. by distance which is appreciably smaller produced this high-energy invention applies, particular, reactors with spectral shift.
