supercritical

(ˌsuːpəˈkrɪtɪkəl)
adj
1. (General Physics) physics (of a fluid) brought to a temperature and pressure higher than its critical temperature and pressure, so that its physical and chemical properties change
2. (Nuclear Physics) nuclear physics of or containing more than the critical mass
ThesaurusAntonymsRelated WordsSynonymsLegend:
Adj.1.supercritical - (especially of fissionable material) able to sustain a chain reaction in such a manner that the rate of reaction increases
critical - at or of a point at which a property or phenomenon suffers an abrupt change especially having enough mass to sustain a chain reaction; "a critical temperature of water is 100 degrees C--its boiling point at standard atmospheric pressure"; "critical mass"; "go critical"

In contrast with the U.S., which is home to just one ultra-supercritical coal-fired power plant, of China's 100 most efficient coal plants, 90 are ultra-supercritical and 10 are supercritical. Ultra-supercritical plants are considered the gold standard in efficiency and emissions reduction, subcritical plants are the least efficient, and supercritical plants fall in the middle of the two.
