Over 60,000 tons of spent nuclear fuel are stored across Europe (excluding Russia and Slovakia), most of
which in France (Table 1). Within the EU, France accounts for 25 percent of the current spent nuclear fuel,
followed by Germany (15 percent) and the United Kingdom (14 percent). Spent nuclear fuel is considered
high-level waste. Though present in comparably small volumes, it makes up the vast bulk of radioactivity.
