PWR-2 DEPLETION STUDIES

Technical Report ·
OSTI ID:4813178
Use of a synthesis depletion technique has provided esti mates of the lifetime behavior of the three-dimensional nuclear characteristics of PWR-2. Both the radial and axial portions of this technique indicate core lifetimes of the order of 10,000 EFPH. A substantial amount of core power is derived from the natural UO/sub 2/ in the blanket, amounting to an average of to 2000 deg F 47% over core lifetime. Of this amount, a significant portion at end of life is produc by the plutonium isotopes, amounting to to 2000 deg F 30% of total co power. Throughout most of core life the limittng threedimensional power densities do not exceed 2.7 times the seed average. Of the initial seed loading of 336 kg of U-235, 138 kg of U-235 are depleted to achieve core life (auth)
