TVO’s corporate social responsibility policy and its practical implementation through the responsibility program form the core of the company’s social responsibility efforts. The goals and actions included in the responsibility program support not only the strategic goals of TVO, but also the aspects of TVO’s operations revealed in the materiality matrix as important for stakeholders.

The significance of responsibility issues to the business activities of TVO and the decision-making processes of the stakeholders is assessed on a regular basis by means of a materiality assessment which is used to identify the aspects affecting responsibility that are the most important for TVO's stakeholders and business activities. Based on the materiality analysis updated in 2016, for TVO the most important aspects of responsibility include a safety culture of a high standard, a good work community, safeguarding the shareholder value, and the supply of electricity to the Finnish people as well as a positive impact on the climate.

The objective TVO has defined for itself is to develop the work community and the safety culture at the same time it implements actions designed to increase the shareholder value. These three essential aspects of responsibility form TVO's responsibility programme which also provides the framework for other daily development and HR efforts. The continuous improvement of the safety culture, the safeguarding of the shareholder value and the development of a good work community are still improvement areas in the 2017 responsibility programme.

The achievement of the goals defined in the programme is reported to the Management Group of TVO Group and to the employees yearly in connection with responsibility reporting. The results are also posted on TVO's Internet site. The results are also posted on TVO's Internet site. The fourth of TVO's material aspects of responsibility, the production of electricity to the Finnish people and a favourable impact on climate, is reported on a yearly basis in connection with responsibility reporting.

A total of 2,602 safety observations were made in Olkiluoto in 2017. Observations have been made by the personnel of TVO Group as well as contractors.

TVO completed in March 2017 a self-assessment of theeffectiveness and coverage of the safety management system, and safety culture. The assessment is carried out every four years. According to the assessment, safety culture at TVO is on level two of the three-level scale.

The activities included in the action plan for occupational safety were executed in compliance with the plan. The accident frequency rate (accidents / one million working hours) is 2.2 in Olkiluoto. This rate does not cover the OL3 worksite, as the Consortium's accidents are reported by the Consortium.
