A safeguards system for pebble-bed reactors is described and explained in detail using the example of the 300 MW(e) THTR-reactor. Continuous loading and unloading of the core during the operation is typical for this reactor. In order to reduce the inspection effort, the system will be based on extensive application of containment and surveillance measures. Material balance will be carried out by means of automatic counting of the fuel element pebbles to be introduced into the core and those leaving the core. Building construction measures will ensure that all fuel elements will have to pass the pebble counter at the entrance and exit of the reactor. The continuous operation of the facility and the counter will provide a continuous supervision of the physical inventory.
