The Ukraine Nuclear Power Plant: What Canadians should know

The Zaporizhzhia Ukraine Nuclear power plant

The Ukraine nuclear power plant in Zaporizhzhia is an important global issue.  It is the largest nuclear power plant in Europe, and contains 6 nuclear reactors.  The power plant is currently under Russian control since March 2022.  Because of the unstable situation of the war of the Ukraine, there has been worldwide concern regarding the safety of this nuclear plant.  If there was an explosion there, an area of up to 30,000 square kilometers around the plant could be effected.

As a precaution,  in August 2022, Global Affairs Canada distributed potassium iodide pills to to Kyiv and diplomats in the surrounding area.

Why Canadians should take notice

In May of 2023 the Nuclear Regulators’ Association  released this statement regarding the Ukraine Nuclear powerplant in Zaporizhzhia:

“We, the members of the International Nuclear Regulators’ Association (INRA), comprising the national nuclear regulators from Canada, France, Germany, Japan, the Republic of Korea, Spain, Sweden, the United Kingdom and the United States, continue to be gravely concerned about the ongoing conflict in Ukraine and the potential serious impacts on the safety and security of its nuclear power plants and facilities.

Consistent with the statement we released in September 2022, INRA members continue to fully support the efforts of the Ukrainian nuclear regulator to maintain safe and secure nuclear facilities. The International Atomic Energy Agency (IAEA) has fulfilled an essential role in ensuring that accurate and up-to-date information is available on the status of the nuclear facilities, and INRA members remain committed to providing support to the IAEA to enable it to maintain its programme of assistance and assurance monitoring in Ukraine.

We commend the courage, dedication and extraordinary efforts of workers who have placed themselves at risk to ensure the continued safety of nuclear facilities in Ukraine. We stand in solidarity with the Ukrainian nuclear regulator, its operator and the people of Ukraine.” –source

The focus on the Ukraine nuclear power plant has highlighted the need to bolster precautions here in Canada. Canada has its own nuclear facilities located in British Columbia, Ontario, and New Brunswick. The Canadian Nuclear Safety Commission (CNSC),  sets strict standards for the safe operation of nuclear facilities and the handling of nuclear materials. Plans are in place to deal with the potential effects of an uncontrolled release of radioactivity, including direct exposure or eating contaminated food. Potassium Iodide pills are recommended for residents in the proximity of these plants.

Potassium Iodide Pills

Potassium iodide pills are a medication that contains stable iodine in the form of potassium iodide. They are commonly used in nuclear emergency situations or during radiation exposure to protect the thyroid gland from radioactive iodine.

During a nuclear incident or release of radioactive materials, such as a nuclear power plant accident or nuclear detonation, there is a risk of releasing radioactive iodine into the environment. The thyroid gland is particularly sensitive to absorbing radioactive iodine, which can lead to thyroid cancer and other thyroid-related health issues.

By taking potassium iodide pills, the thyroid gland becomes saturated with stable iodine, which helps to block the absorption of radioactive iodine. The stable iodide competes with the radioactive iodine, preventing it from being taken up by the thyroid gland and reducing the risk of radiation-related thyroid damage.

Conclusion

The Ukraine nuclear power plant situation serves as a reminder of the potential risks involved with these facilities. Countries worldwide, including Canada, have dedicated efforts to establish robust safety protocols, ensuring the secure operation of nuclear facilities and the responsible handling of nuclear materials. Measures like potassium iodide pills serve as vital tools during nuclear emergencies to protect vulnerable populations from harmful radioactive exposure. As technology advances and global cooperation strengthens, the commitment to nuclear safety remains steadfast, reaffirming the collective responsibility to harness the benefits of nuclear energy while mitigating potential risks. Through a combination of vigilance, innovation, and informed decision-making, the international community can continue to promote nuclear safety and pave the way for a safer, sustainable, and more secure nuclear future.
