The Enormous Task of Nuclear Waste Storage

“The Koeberg spent fuel pool storage capacity in South Africa  is currently over 90% full. (These) pools will reach (their) capacity by April 2020,” Eskom, the South African utility, told Reuters in a statement on Nov. 25, 2019.  Koeberg produces about 32 tonnes of spent fuel a year. Fuel assemblies, which contain radioactive materials including uranium and plutonium that can remain dangerous for thousands of years, are cooled for a decade under water in spent fuel pools.

In 2016,  Eskom paid an estimated 200 million rand ($13.60 million) for an initial batch of seven reinforced dry storage casks from U.S. energy company Holtec International to help keep Koeberg running beyond 2018.  Eskom now has nine new unused casks on site, each with an individual capacity of 32 spent fuel assemblies, with another five expected to be delivered soon.

The 14 casks should ensure there is sufficient storage in the spent fuel pool until 2024, Eskom said, ahead of a tender for an extra 30 casks….Anti-nuclear lobby group Earthlife Africa said South Africa could not afford the social, environmental and economic costs associated with nuclear waste.  “We have a ticking bomb with high-level waste and fuel rods at Koeberg,” said Makoma Lekalakala, Earthlife Africa’s director.

What to Do with 56 000 Drums of Nuclear Waste: Japan

At least 1.9 trillion yen ($17.12 billion) will be needed for the planned scrapping of 79 nuclear facilities, including the failed Monju prototype fast-breeder reactor, according to the Japan Atomic Energy Agency (JAEA).

However, the JAEA’s estimate, released on Dec. 26, 2018 does not include maintenance expenses for the facilities nor costs to deal with leftover uranium and plutonium, meaning the actual tally could increase by hundreds of billions of yen.  State subsidies account for the bulk of the JAEA’s budget, so taxpayers will likely foot most of the bill.  The agency plans to shut down 79 of its 89 nuclear facilities, including research reactors and test buildings, over 60 to 70 years due to aging and the huge costs needed for their continued operations under stricter safety standards.

According to the JAEA’s estimate, the cost to decommission the Tokai spent nuclear fuel reprocessing plant in Ibaraki Prefecture will be 770 billion yen.  But the overall cost would reach nearly 1 trillion yen if expenses on dealing with highly radioactive liquid waste, which is left after plutonium is extracted from spent fuel rods at the plant, are included.

The problem-plagued Monju prototype fast-breeder reactor in Tsuruga, Fukui Prefecture, cost taxpayers more than 1 trillion yen ($8.82 billion) despite running for only 250 days during its two-decade operation. ..But the JAEA currently has no plan on how to handle plutonium stored at the facilities. In addition, no decision has been made on what to do with radioactive waste from the 79 facilities that could fill more than 560,000 200-liter drums.
