Method for extracting spherical fuel elements from a pebble bed reactor, and extraction device for carrying out this method

摘要

In a method for the dosed extraction of spherical or similar fuel elements from a pebble bed reactor, the fuel elements are withdrawn from the interior of the reactor, piled up and finally extracted individually. In order for it to be possible to extract these fuel elements in a simple way and without a large space requirement, the fuel elements (5, 14, 28) are deflected, after being withdrawn, and subjected to a resistance such that self-retention gives rise to a pile whose surface is at least partially freely accessible.
