White And Red Commissioning

Mr. Cohen
To ask the Secretary of State for Defence if he will make a statement on the differences between white commissioning and red commissioning.

Mr. Aitken
White commissioning is the process of proving that new plant and facilities operate safely and satisfactorily using similar but non-radioactive materials. Red commissioning is the process of proving that the new plant facilities operate safely and satisfactorily using limited amounts of the actual radioactive materials.
