Sentences with phrase «efficient fast reactors»

The resource gains would be modest, whereas the long - term waste problem would remain, and the entire effort would delay for only a short time the need for efficient fast reactors.

Not exact matches

In its efforts to develop safer, cheaper, and more efficient nuclear reactors, the Idaho National Laboratory has researched half a dozen next - generation reactor designs; these two (the sodium - cooled fast reactor and the very - high - temperature reactor) are the most promising.

While fast reactors are up to 200x more resource efficient, they require 3x or more fissile atoms to start up initially.

Each dollar spent on a new reactor buys about two to ten times less carbon savings and is 20 to 40 times slower, than spending that dollar on the cheaper, faster, safer solutions that make nuclear power unnecessary and uneconomic: efficient use of electricity, making heat and power together in factories or buildings («cogeneration»), and renewable energy.

Replacement of the current thermal variety of nuclear fission reactors with nuclear fission fast reactors, which are 100 times more fuel efficient, can dramatically extend nuclear fuel reserves.
