ABSTRACT:
5. A grid structure for a nuclear reactor fuel assembly comprising a plurality of connecting members forming [at least one] longitudinally extending [opening] peripheral and inner fuel element openings through each of which openings at least one nuclear fuel element extends, said connecting members forming wall means surrounding [said] each peripheral and inner fuel element opening, a pair of rigid projections .Badd.longitudinally spaced from one another .Baddend.extending from a portion of said wall means into [said] each peripheral and inner opening for rigidly engaging [said] each fuel element, respectively, yet permit individual longitudinal slippage thereof, and resilient means .Badd.formed integrally on and from said wall means and .Baddend.positioned in [said] each peripheral and inner opening in opposed relationship with said projections and located to engage said fuel element to bias the latter into engagement with said rigid projections, respectively.
