Monitoring safety

Fennovoima’s safety culture has been continuously monitored since 2008.

Fennovoima’s internal audits include safety culture as one of the audited elements. Questionnaires are used to collect employees’ views on safety culture. All teams evaluate annually how the safety culture principles are realized in daily work. These findings are summarized and reported to management, and corrective actions are taken when needed.

Safety observations

Safety observations are openly shared in Fennovoima. In order to ensure that all observations relevant to nuclear safety are reported and acted upon, a new Observation feature was implemented in our integrated data management system during 2016. All personnel at Fennovoima may report any issue they consider important for development of operations, have the observation investigated, and get feedback on it. All types of observations (non-conformities, safety concerns and initiatives) can be made anonymously in the new system.

The aim of the observation system is to facilitate organizational learning and employee involvement. A safety concern can be reported if a person feels an issue is not getting the attention warranted by its significance. This issue can concern e.g. human resources, legal issues, project management, engineering, nuclear safety, security, occupational health and safety, or safety culture in general. This process supports good safety culture by giving a legitimate route for reporting and by increasing transparency in the organization.

All observations are processed

The observations are evaluated and processed without delay, at the organizational level appropriate to their significance, and any improvements carried out are communicated appropriately.

In 2016, a total of 18 concerns were received and handled. Two main apparent cause categories underlying the concerns were communication and collaboration, and processes and procedures. The concern process, and safety culture development in general, was also monitored by the independent Nuclear Safety Committee. Safety culture is also followed in Fennovoima’s management reviews.


Nuclear Safety Assessment

Nuclear Safety Assessments compare the characteristics and performance of the plant, systems, equipment, structures, working methods and quality management to the requirements set for them. Through Safety Assessment, insight into the current level of performance and the adequacy of safety requirements is established.

Nuclear Safety Assessment is performed for all documents constituting or affecting the overall safety case of the plant. The overall safety case is the collection of arguments and evidence for the nuclear safety of the plant and is based on the plant technology, the organization and the site.


Nuclear Safety Committee

The Nuclear Safety Committee (FNSC) convenes on a regular basis to handle safety-related topics and issue recommendations thereon, as required in the Government Decree on the Safety of Nuclear Power Plants (717/2013). The FNSC provides advice to the CEO and the management of Fennovoima on all topics related to nuclear safety.

The FNSC has the following specific tasks for the licensing phase of the Hanhikivi 1 nuclear power plant:

  • with its experience, to ensure that nuclear safety is taken into account in the development of the organization and management system
  • with its leadership, to promote development of good nuclear safety culture
  • with its networks, to assist in adoption of best practices in nuclear safety management
  • with its knowledge, to support in addressing technical development and nuclear licensing issues, which have nuclear safety aspects
  • with its expertise, to provide comments on plans, manuals, reports and other documents having nuclear safety relevance

The members of the Nuclear Safety Committee are: Ami Rastas (chairman), Juhani Hyvärinen, Kirsi Kavonius-Hietanen, Peter Tuominen, Gabor Vamos and Timo Äikäs.
