Americium-241 has been produced in small quantities in nuclear reactors for decades, and many kilograms of 241 Am have been accumulated by now. [4]: 1262 Nevertheless, since it was first offered for sale in 1962, its price, about US$1,500 per gram of 241 Am, remains almost unchanged owing to the very complex separation procedure.

The critical masses of the two readily available isotopes, 241 Am and 243 Am, are relatively high – 57.6 to 75.6 kg for 241 Am and 209 kg for 243 Am. [97] Scarcity and high price yet hinder application of americium as a nuclear fuel in nuclear reactors.

The most important isotopes of these elements in spent nuclear fuel are neptunium-237, americium-241, americium-243, curium-242 through -248, and californium-249 through -252. Plutonium and the minor actinides will be responsible for the bulk of the radiotoxicity and heat generation of spent nuclear fuel in the long term (300 to 20,000 years in ...
