Zusammenfassung:FIELD: nuclear power engineering; assembling pressurized-water reactor core. ^ SUBSTANCE: pressurized-water reactor core is assembled so that when bent fuel elements are installed at core edge, they are respectively positioned with their convex part facing outside. Forces developed when reactor is running enlarge smaller clearances between fuel elements at the sacrifice of larger ones and prevent bending of fuel elements. ^ EFFECT: greatly reduced economic losses caused by fuel element bends. ^ 6 cl, 13 dwg
