The long-term disposal of
plutonium waste remains a significant challenge for the nuclear industry and policymakers worldwide.
长期处置钚废物仍然是全球核工业和政策制定者面临的一大挑战。
Due to its ability to sustain a chain reaction,
plutonium is used as fuel in certain types of nuclear reactors, such as fast breeder reactors.
由于其能够维持链式反应的能力，钚被用作某些类型核反应堆（如快中子增殖反应堆）的燃料。
Researchers continue to study the chemical and physical properties of
plutonium to improve understanding of its behavior in various environments.

It is meant to be used alongside fissile materials such as recycled plutonium and uranium.
The International Atomic Energy Agency said work on the use of thorium as a fuel for nuclear power began at about the same time that the first studies on uranium and plutonium started.
He believes China aims to move from conventional nuclear power reactors to a "fully closed nuclear fuel cycle based on fast breeder reactors, spent fuel reprocessing and the use of recycled plutonium fuel".
他认为，中国的目标是从传统的核能反应堆转向“基于快中子增殖反应堆、乏燃料后处理和循环利用回收钚燃料的完全闭式核燃料循环”。
"If that is the case, Hibbs said other countries may follow in projecting that nuclear power will be sustainable for centuries and that the risks associated with an industrial-scale "plutonium economy" are socially, economically, environmentally and politically acceptable.
