plant as a whole, have yet to be further studied and analysed. As the design of the various systems of a nuclear power plant is a very complex problem involving many factors, all of them should be taken together and considered in their totality. Though generally speaking, it is possible to design a PWR nuclear power plant by breaking it
breaking it down into over a hundred systems, yet the coordination of functions among systems, the matching of parameters, the choice of model for equipment, and the operation of the systems all have close and inseparable relations of their own. The addition or removal of a system must be done taking into account not only the functions of that system but also the consequences it
it will have on other systems and the whole plant. In other words, a conclusion can only be drawn after thorough
Therefore, analysis and argumentation.
