Tesis doctoral de José Carlos Llopis Alvarez
This doctoral thesis presents the incorporation of realistic models of control systems, protections, permissive circuits, automatic signals and manual actions in a thermalhydraulic model based in relap. In order to develop this models has been used the internal components of relap, this is a new practice in the ambit of use thermalhydraulic codes best estimate. The thesis also supposes the imbricación of two initiatives that arose after the accident. Te thesis also supposes the imbrications of two ways that they were impelled after the accident of three miles island, unit 2: the development of emergency procedures operation and the impulse of the codes best estimate. Is possible to use realistic models for the verification of these procedures. A methodology of work has been established, in the first place in standardizing the models of control components that assures a behaviour near the reality makes sure and in addition reduces the user effect. The control models of the npp vandellí²s ii and ascó i & ii have been developed from de design logic planes and a functional verification of such has been made. For the model of the npp ascó i & ii the extension of the validation has been two transitory and for the npp vandellí²s ii has been five transitory. It is exposed how with these models design improvements can be proposed, fundamentally of control, and other applications in areas of formation and operation and its use for validation of simulators of training of operators, preparation of emergency manoeuvres and verification of design criteria. The examples of design improvement that appear they have its origin in the analysis of transitory with undesired reactor trips or some variable of plant approaches the trip set point. With the reduction of the probability of reactor trip an improvement in the availability of the plants can be obtained and also to contribute to the security. Also one is the process of confluence of the models the npp vandellí²s ii and ascí i
