In 2025, France may also have one of the first long-term geological repositories for radioactive waste. The country has about 44,300 cubic meters of the troublesome stuff now, 2,300 of which is high-level waste.
Declan Butler reports for Nature:
The high-level waste includes the radioactive fission products caesium-134, caesium-137 and strontium-90, and minor actinides such as curium-244 and americium-241. Most nuclear fuel in France is reprocessed to extract useful uranium and plutonium, and to concentrate the waste. Although this high-level material comprises just 0.2% of France’s nuclear waste by volume, it accounts for 95% of its total radioactivity.
At about 1,000 sites around the country, France holds nuclear waste of various classifications, managing the materials according to their radiation levels and half-lives. For instance, there are disposal sites in Soulaines (for low- and medium-level radioactive substances with shorter half lives) and east of Paris, the Morviliers site holds very low-level wastes.
Butler takes a tour of the on-site laboratory for a future subterranean storage space for high- and medium-level wastes. The facility would exist about 1,600 feet underground near the town of Bure, encapsulated in 150-million-year-old rock (that according to French geologists hasn’t moved around much in the last 20 million years nor is expected to anytime soon). Testing the rock, a type of clay, and their containment technology, ANDRA’s, the French National Radioactive Waste Management Agency, lab research bill comes in at around $130 million each year.
