SAFETY CULTURE

All of TVO’s employees, suppliers, and subcontractors are committed to an uncompromising safety culture.

According to the safety culture, all factors that affect the nuclear power plant’s safety receive attention in proportion to their significance and are given priority in decision-making. Continuous improvement and appropriate safety culture are inherent features of all day-to-day work. In day-to-day work, the safety culture refers to the STAR principle.

In practical work, safety culture refers to e.g. the STAR principle. The STAR approach means that employees should always first Stop and Think, and only then Act, and finally Review whether everything went as it should have. TVO encourages its employees to report defects, and aims to maintain a low threshold for such reporting.

Safety culture principles:
  • Follow the approved procedures and instructions without compromise
  • Make sure that you and others use safe working practices and work under safe conditions
  • Stop and think before you act, and review the consequences of your actions
  • Report all problems and deficiencies without delay
  • Maintain an atmosphere where reporting can be done freely and without blame
  • Question practices and develop operations in the spirit of continuous development


Towards the highest safety culture level

The status of safety culture is at TVO reviewed through extensive self-assessments which have been carried out since 2004. In March 2017, a self-assessment of the functionality and coverage of the safety leadership system and the safety culture was completed at TVO. It is performed every four years. According to the assessment, TVO’s safety culture is on level two on IAEA's three-level scale, i.e., the maintenance of safety is based on proactivity and initiative. TVO has a safety culture programme in place aiming at achieving the highest development level of the safety culture defined by IAEA, that of a learning organisation.
