Beschreibung
Zusammenfassung:	FIELD: nuclear power engineering. ^ SUBSTANCE: proposed fuel assembly designed to perform dual function of energy liberation and neutron flux control in pressurized water reactors, especially VVER-440 ones, has fuel bundle whose uranium dioxide mass is 69.16 to 159.25 kg; outer and inner diameters of fuel element are 6.00 / 10-3 to 8.00 / 10-3 m and 5.09 / 10-3 to 6.79 / 10-3 m, respectively, for bundle of 174 to 216 fuel elements, or uranium dioxide mass in bundle is 88.67 to 149.53 kg; outer and inner diameters of fuel element are 7.80 / 10-3 to 8.79 / 10-3 m and 6.62 / 10-3 to 7.47 / 10-3 m, respectively, for bundle of 132 to 168 fuel elements. ^ EFFECT: reduced fuel element unsealing probability, enlarged power variation range, improved heat absorption capability. ^ 7 cl, 5 dwg
