abstract:In mathematics, a nuclear operator is a compact operator for which a trace may be defined, such that the trace is finite and independent of the choice of basis (at least on well behaved spaces; there are some spaces on which nuclear operators do not have a trace).
France generates 80 percent of its electricity with nuclear, and its state-owned firms are world leaders: Paris-based EDF is the largest operator of nuclear power plants worldwide, while Areva is the largest provider of nuclear services and technology.
