Packaging of intermediate level nuclear waste

Packaging of low level nuclear waste

Application to the storage of packages of nuclear waste or dangerous and/or fragile materials.

A LILW-SL package consists of 15-20% radioactive waste and 85% encapsulation.

Preferably, the object that is to be probed is a radioactive waste packet having a thick absorbent concrete container.

Nearly 80,000 packages of nuclear waste have been processed by bituminisation since 1966.

It includes surface facilities, for receiving and preparing the waste parcels, and underground structures located around 500m deep in a layer of argillite rock, for storing the waste parcels.

Today, the site no longer receives waste and is in the process of closing.

The pipe is used to stabilize the borehole and then to receive the waste containers.

This cross-section of the E-EV-SE vitrified waste store in the Hague illustrates the principle of harnessing natural convection to cool vitrified waste packages located in shafts.

50,000 of these bituminous waste packages are in principle to be disposed of in the Cigéo project facility.

Orano will also transport the final waste component packages to a designated storage site.

ASN considered that priority should be given to “efforts to neutralise the chemical reactivity of bituminous waste packages.
