light water reactor fuel element with the spacers and on the top edge of the insulation glass distance frame randstegs sitting inside curved flag

摘要

A light water reactor (LWR) fuel element (1) has upper peripheral spacer grid tabs (23) with inwardly bent undersides inclin towards the fuel rods (7A, B). A LWR fuel element (1) has a spacer grid (9) with peripheral walls (15A, B) fitted, on their upper edges (17), with tabs (2 which face away from the coolant flow (3) and which have inwardly bent undersides extending into an interspace (25) between firs and second fuel rods (7B, 7A). The novelty is that part (27B) of the inwardly bent underside is bent at an angle towards the fir fuel rod (7B). Preferred Features: The inwardly bent underside has a second part (27A) which is bent at an angle towards the sec fuel rod (7A).
