Determinación de las restricciones de operación de un sistema de tiro térmico helicoidal durante un accidente de pérdida total de refrigerante

Abstract

In the present work the heat transfer processes applied to nuclear safety were studied for the development of thermal firing equipment that could act as the fuel chamber of a fixed bed nuclear reactor (FBNR). To guarantee the reliability of the software used, the reliability index was established. It was established that the difference of temperatures obtained by means of real experimentation and by means of virtual experimentation have a centered leptokurtic distribution with a mean value of 1.4 ° C and a standard distribution (2σ) of 1.0 ° C. The probability of occurrence of an accident of these characteristics was determined by the tie - tie model, with the main emphasis on the generation of an event tree that established the different exit scenarios in the event of a possible eventuality in conjunction with its probability of syncope. The determined scenario was the case in which there is no flow of water inside the thermal draft equipment and that the water shield surrounding it is dry, with a probability of occurrence of 2.5 × 10-6%
