After recalling the entry of nuclear energy into energy production in France, the paper emphasizes the evolution of techniques applied in the designing of French nuclear power plants and describes the means employed for reducing costs per kwh of EDF2 and EDF3 compared with EDFl: the electric power per ton of urarium varies from 493 kw/ ton for EDFl to 970 kw/ton for EDF3. For this purpose the thermal and electric power of units are changed, respectively, from 290 Mw(t) for EDFl to 1200 or 1600 Mw(t) for EDF3 and from 28 to 250 Mw. The results are obtained by an improvement in neutronic characteristics, developments in nuclear fuel technology, and simplification of the system of charging the reactor, with an increased means of maintenance; the EDF2 heat-exchangers have been so designed as to increase the unit power of the elements, which will attain 9 Mw(t), as against 3 for EDFl. For EDF3 an advance project forecasts a thermodynamic layout with only one pressure stage. A description is given of the burst-slug detection systems, and an appendix gives a detailed comparative table of EDFl, EDF2, and EDF3 plant characteristics. (auth)
