The capsule has a hollow sheath (8) in which a radioactive body, e.g. a damaged nuclear fuel pin, can be encapsulated and end sealing plugs (9, 10), which have vent holes (13, 22) which are sealed by valves (14, 23) held closed by springs (15, 24). Also claimed are: (a) a fuel element for a nuclear reactor where the above capsules can be inserted into the spacer grids; and (ii) a process for assembling the above capsules. |
