Questions & Answers

Q: Why did Finland decide to expand its nuclear power capacity?

Finland aims to reduce its reliance on foreign energy and achieve carbon neutrality by 2035. Expanding nuclear power capacity would provide a reliable and clean source of energy.

Q: What were the challenges faced during the construction of the OL3 reactor?

The OL3 project experienced delays, cost overruns, design defects, safety system issues, and contractual disputes. Despite these challenges, the reactor has received its operation license and is expected to begin commercial production in early 2022.

Q: How do countries currently handle radioactive waste from nuclear power plants?

Most countries store radioactive waste in pools or sealed dry storage facilities. However, this method requires ongoing mechanical and human intervention and is not a long-term solution.

Q: How does Finland's deep geological repository solve the problem of radioactive waste?

The Onkalo repository, based on the Swedish disposal method known as KBS3, uses boron steel canisters and corrosion-resistant copper capsules to permanently bury the spent fuel in individual holes filled with bentonite clay. No further intervention is required to contain the waste.

Summary & Key Takeaways

• Finland aims to reduce its reliance on foreign energy and achieve carbon neutrality by 2035 by constructing a third-generation pressurized water reactor (EPR), named OL3, and a deep geological repository for spent nuclear fuel.

• The OL3 project faced numerous delays and cost overruns but has received its operation license and is expected to begin commercial production in early 2022, providing 14% of Finland's energy needs.

• The deep geological repository, known as Onkalo, is a billion-dollar project that will permanently dispose of spent nuclear fuel in tunnels buried half a kilometer below ground, eliminating the need for long-term mechanical and human intervention.
