Workers Seek Shelter As Hanford Nuclear Complex Issues Leak Alert


By Alex Kimani - Dec 23, 2024, 



Workers at the Hanford nuclear site were ordered to take cover on Friday after a large holding tank with ammonia vapor was discovered to be leaking near the vitrification plant in the 200 East Area. Workers in that area were told to shelter in place with doors, windows and ventilation closed while other workers were told to avoid the 200 East Area. The Hanford Site is a decommissioned nuclear production complex operated by the United States federal government on the Columbia River in Benton County in the U.S. state of Washington

The 200 East Area has a vitrification plant, built and commissioned to treat the tank waste for disposal. The waste was left from the past production of plutonium from World War II through the Cold War for America’s nuclear weapons program. Today, there are 177 underground storage tanks on the Hanford Site, holding about 56 million gallons of highly radioactive and chemically hazardous waste.

The Hanford incident highlights the ongoing challenges of dealing with nuclear waste. Currently, there are thousands of metric tons of used solid fuel from nuclear power plants worldwide and millions of liters of radioactive liquid waste from weapons production sitting in temporary storage containers, some of which have begun leaking their toxic contents. Nuclear waste is notorious for the fact that it can remain dangerously radioactive for many thousands of years.

Thankfully, the world is now closer to finding a permanent solution to its nuclear menace: Finland has built the world’s first deep-earth repository where it will bury nuclear waste for 100,000 years starting 2026. Dubbed ‘‘Onkalo’’, the repository is entombed in a bedrock more than 400 meters below the forests of southwest Finland. The facility sits atop a warren of tunnels sited next to three nuclear reactors on the island of Olkiluoto, approximately 240 kilometers from the capital of Helsinki. The Onkalo project is based on the so-called “KBS-3” method developed by the Swedish Nuclear Fuel and Waste Management Company. KBS-3 is based on a multi-barrier principle whereby if one of the engineered barriers were to fail, the isolation of the radioactive waste is not compromised.

“Basically, the Onkalo project is that we are building an encapsulation plant and disposal facility for spent fuel. And it’s not temporary, it’s for good,” Pasi Tuohimaa, head of communications for Posiva, told CNBC via videoconference. Posiva is tasked with the responsibility of handling the final disposal of spent nuclear fuel rods at Onkalo.

Russia Expands Global Nuclear Footprint Despite Western Pushback

By Tsvetana Paraskova - Dec 23, 2024


Russia is looking to maintain its position as “one of the biggest builders of new nuclear plants in the world,” a top envoy of Russian President Vladimir Putin told the Financial Times in an interview published on Monday.

“We are building more than 10 different units around the world,” Boris Titov, Putin’s special representative for international cooperation in sustainability, told FT.

“We need a lot of energy. We will not be able to provide this energy without using . . . nuclear,” the official said.

This type of energy is safe and low-carbon, Titov added.

Russia currently has nuclear power plants under development and construction in countries such as China, India, Iran, Bangladesh, Egypt, and Turkey, among others.

Russia’s ambitions to boost its global influence in nuclear power fleets come as the West seeks to diminish its dependence on Russian nuclear fuel and technology.

Yet, the Western countries will need additional incentives and sanctions on Russia to reduce their dependence on the Russian supply of nuclear fuel, according to French company Orano, one of the top Western suppliers of enriched uranium.

“To entirely disconnect from Russia, we need new capacities, and industrial groups will only invest if they have long-term contracts,” Orano’s CEO Nicolas Maes told the Financial Times in an interview in October.

France’s Orano and Urenco, a consortium created in 1970 by the governments of Germany, the Netherlands, and the UK, are the main Western competitors of Russia’s state-owned nuclear energy firm Rosatom.

Europe has not sanctioned Rosatom or Russian nuclear fuel supplies as dozens of nuclear power stations in the eastern EU member states have been built by Russian companies and supplied with Russian nuclear fuel.

As many countries are now looking to nuclear power to cut emissions and reliance on imports of oil and gas, they would need to cut their dependence on enriched uranium from Russia.

But in order to reduce reliance on Russia, western contractors and suppliers would need visibility over the long-term demand, the chief executive of France’s Orano told FT.
