Analysis of the stability of the instrumented fuel temperature type flip, for operation times between 0 and 72 H at 1 MW (Final report of the project); Analisis de la estabilidad de la temperatura del combustible instrumentado tipo flip, para tiempos de operacion entre 0 y 72 H a 1 MW

Abstract

It was found that the behavior of the temperature of the three thermo pars of the instrumented fuel of the Reactor in operations in stationary state to 1 MW is stable. For times of operation minor to 3 h, the standard deviations are of the order of 0.5%, while it stops operations with more duration to 3 h, the presence of the poisons for fission has an important effect being obtained standard deviations until of 2.7% for 72 h in continuous operation to 1 MW. During the outburst stages and court of the reactor, the found deviations standard were of 30%. It was not rhythm some in the small ones fluctuations that it presents the temperature of the thermo pars of the fuel. After a detailed analysis of the temperature response of the fuel in different positions of the core, it was selected to the position C-6 at 180 for the relocation of the instrumented fuel so that it has a pursuit but appropriate of the temperature during operations in stationary state and in pulse mode. It was found that the influence that its present the control bars on the temperature of the Flip fuel in the rings C and  More>>
