Designers and Builders Viewpoint on the Safety of Nuclear Power Plants.

Taking a pressurized light water reactor as an example, the authors point out how the various safety rules serve as a guide to the constructor of a nuclear power station at each stage, from its designing to its first operating. The successively review: the three shields place between the fissionable material and the environment; the study of the core of the reactor; the conception of systems (of control, of protection, of servitudes); the designing and construction of pressure vessels; the trial runs; the equality of the research and realization which is the best guarantee for the safety of the nuclear plants.
