FIELD: nuclear power engineering. SUBSTANCE: fuel element with elongated fuel-element can 2 has locking body 12 that in one locking position attained due to turning of cladding 6 about longitudinal axis enters slot 16 in cross-section of can 2 on inner side of elongated can 2 and that is protected against spinning in this locked position due to locking element 18 which is, essentially, retaining body mounted on locking body 12 for radial displacement of can 2 and provided with retaining drilling on wall of can 2 or it may be made in the form of retaining body mounted on locking body 12 for longitudinal displacement of can 2 and provided with retaining notch 22 on final edge of can 2 or with retaining slot 21 on inner side of can 2. EFFECT: improved design. 1 dwg |
