Tests for Process Control During Treatment of Low and Medium Radioactive Waste in Practise

Objective

Total waste treatment process from waste release up to interim/final storage has to be controlled. Continuous process control is preferable to verification just before storage because of its higher reliability, traceability and the possibility for corrections of the system.

This research project refers to the development of test methods which are necessary to control the process of conditioning of radioactive waste. The emphasis lies upon measurement techniques and operations.

On the basis of the international exchange of information between the partners recommendations will be formulated with respect to standard testing methods and procedures where specific quality systems can be based on.

This research project refers to the development of test methods necessary to control the process of conditioning radioactive waste. The emphasis lies upon measurement techniques and operations. On the basis of the international exchange of information between the partners, recommendations will be formulated with respect to standard testing methods and procedures which specific quality systems can be based on. The study incorporates a description of waste pretreatment, cementation, packaging, transport and preparation for storage of low and medium wet radioactive waste from nuclear power plants in Belgium, Germany and the Netherlands and the corresponding quality actions and requirements. A literature survey was also made of chemical and radiological characterization methods.
Work programme:

The decisive elements for process control are tests and procedures to check if the criteria are met. Therefore, in this research project test methods and procedures are being developed with respect to the chemical, radiological and mechanical/physical properties of radwaste.

The main topics to be addressed are covered in the following subject headings :
Inventory of Process descriptions of waste treatment
Chemical characterization
Radiological qualification test methods
Mechanical and physical qualification tests
Validation of test methods and evaluation

There is also a close co-operation with CEA/CEN and Taylor Woodrow.
