Pro-activity and continuous improvement are TVO values. Nothing is so good that it cannot be improved, and pro-activity helps prevent malfunctions.

TVO pursues a policy of systematic long-term planning. Ways of improving equipment, procedures and instructions are constantly being actively sought, and any shortcomings observed are corrected or eliminated.

TVO keeps the OL1 and OL2 units in a condition as good as new while also systematically developing them to conform to current requirements.
