PURPOSE: To provide a fuel assembly in which generation of eutectic is suppressed without splitting the plate while allowing highly accurate bending work and high degree of burn-up is realized by increasing the number of fuel element grids.
CONSTITUTION: A resilient supporting plate 15 has right and left bent side faces 15R, 15L which are spot welded at the edges thereof, i.e., welding points L1, L2 or R1, R2, to a round cell 8. Each of the bent side faces 15R, 15L is provided with two openings 16R, 16L at substantially same height as the plate contact part 13A of a spring member 13. Consequently, the plate contact part 13A is inserted, at the end thereof, into the opening 16L when the spring member 13 is shifted to the left and into the opening 16R when the spring member 13 is shifted to the right.
