USDOE Problems With [Not] Storing Nuclear Waste

Although they are nearly at the final depth, the work thus far has been primarily to construct the 4-km long access tunnel. The facility is not scheduled to accept the nuclear waste until 2020 but […]

As the U.S. continues to fight over hurdles for its Yucca Mountain Nuclear Waste repository, Finland is on track to become the first country with a permanent storage facility for spent fuel rods from nuclear reactors. Their Onkalo tunnel, on the western coast of Finland will eventually stretch for 5-km (2-miles) and reach a depth of 500-m (1,600-ft) in solid granite bedrock. Once at depth a grid of horizontal tunnels will be constructed. Vertical storage holes will be excavated in these horizontal shafts, and the spent rods, encased in steel cannisters with copper corrosion protection, will be placed on layers of bentonite clay. The clay will cushion the cannisters and protect them against long term geologic movement. The clay also serves as a barrier to water, swelling in its presence to seal off any cracks or conduits for water that could potentially transport nuclear contamination in the distant future if the primary measures of protection are compromised. The tunnels will eventually be backfilled with bentonite and rock. The facility is projected to open in approximately 15 years at a cost of about 3 billion euros. The projected life of the facility is through 2100.  Links after the break. (Illustration by BBC)

Apparently the French are working on their nuclear waste storage facility, they already have a research laboratory constructed about 1/2-km underground. The actual repository will come on line around 2025 and be one of the […]
