ONDRAF/NIRAS has set up a management system designed to guarantee that the general public and the environment are protected against the potential hazards arising from radioactive waste. The primary objective of this system is to guarantee safety. With this aim in mind, the system is based on two principles: containment of radioactive materials to prevent them from being dispersed into the environment, and shielding against ionising radiation. Both of these principles are applied at every stage of the management process.

The management system of ONDRAF/NIRAS includes two aspects :

an integrated system;
an acceptance system.


An integrated system

This system covers all aspects of management ranging from the origin of waste to its transport, processing, interim storage and long-term management.

Schematically, this integrated system can be represented as follows :


Decommissioning Inventory Enriched fissile materials Inventaris Inventaris Ontmanteling

Limiting, sorting, identifying Reduce the volume Processing Interim storage Long-term management Transporting


An acceptance system

The safety of radioactive waste management not only depends on the quality of the design and construction of the processing, temporary storage or disposal infrastructure, but also on the quality of the waste accepted by ONDRAF/NIRAS. In order to be managed safely, both in the short and the long term, the waste transferred to ONDRAF/NIRAS must meet certain specific requirements.

To that end, ONDRAF/NIRAS has developed an acceptance system (*) that consists of the following three stages:

The drawing up, by ONDRAF/NIRAS, of acceptance criteria ;
The qualification, by ONDRAF/NIRAS, of the processing/conditioning and storage facilities, including the measuring facilities and methods used to characterize the waste ;
The acceptance, by ONDRAF/NIRAS, of the radioactive waste in accordance with the acceptance criteria.

(*) This acceptance system has been certified according to the international ISO 9001:2000 standard.
