Nuclear safety is paramount in the Hanhikivi 1 project

Nuclear technology and safety culture go hand in hand in ensuring the safety of a nuclear power plant. While confirming the safety by technical design, we also develop of our safety culture in compliance with the shared safety principles established for the Hanhikivi project.

The reliable operation of a nuclear power plant is ensured by successful plant design and careful maintenance and operation. The primary objective of the Hanhikivi 1 plant design is to prevent operational disturbances during normal operation. However, the nuclear power plant is designed to be used safely under all foreseeable operating conditions from normal daily operation to nuclear power plant outages and in the event of a severe accident.

The main safety systems of the Hanhikivi 1 plant, such as emergency cooling systems, will use both active and passive safety systems. Passive cooling systems use only natural forces, for example, gravity, to function and thus do not require any electricity or other external energy sources to maintain operation. In addition, Hanhikivi 1 will include, for example, a core catcher used for the management of severe reactor accidents, programmable I&C systems, and a reactor containment building resistant to the collision of a large commercial aircraft.

Hanhikivi 1 plant's safety is comprehensively assessed at various stages

A positive safety assessment by the Finnish Radiation and Nuclear Safety Authority is a prerequisite for the construction permit for the Hanhikivi 1 nuclear power plant and the commencement of construction of the power plant. During construction, Fennovoima and the Finnish Radiation and Nuclear Safety Authority will monitor the construction of Hanhikivi 1 and its safety at all stages. The plant will be constructed in accordance with safety requirements using approved plans and procedures.

The safety of Hanhikivi 1 is being assessed as a whole before the operating license is granted, and the power plant may not be used until the Finnish Radiation and Nuclear Safety Authority has determined that the plant and the operational organization meet the set safety requirements.

In the Hanhikivi 1 project, there are strict requirements for the supply chain

An extensive supply chain is involved in constructing the Hanhikivi 1 nuclear power plant and manufacturing the plant components. Therefore, ensuring safety is also paramount in supply chain management.

Deliveries that are important for safety are subject to a higher number of requirements that are stricter than the requirements set for deliveries with no nuclear safety significance. Such deliveries can only be acquired from suppliers who have prerequisites for operations that meet the statutory safety requirements and have adopted audited quality management and quality assurance procedures.

Safety culture is essential for nuclear safety

Good safety culture is about respecting safety, having the right understanding of safety and dangers, being alert, bearing your responsibility, and ensuring that there are good prerequisites for working, among other things. Structural and technical factors in the organization also influence the safety culture.

Fennovoima, RAOS Project, and Titan-2 are continuously developing their own safety culture and cooperating closely on the Hanhikivi peninsula to develop the safety culture in the project area. The common goal is clear: a nuclear power plant that is safe and functional in all respects. Therefore, we develop and evaluate a safety culture throughout the life cycle of the Hanhikivi 1 project.
