Description

The cold neutron production of hydrogenous materials was studied, taking into account their radiation resistance, for the conceptual design of a cold neutron source for the RA-3 reactor.Low spontaneous release of chemical energy was found in mesitylene.Libraries for hidrogen in mesitylene were generated using the NJOY nuclear processing system and the resulting cross sections were compared with experimental data.Good agreement between measurements and calculations was found in those cases where data are available.New calculations using the RA-3 geometry and these validated libraries will be performed

Abstract (Spanish)

Se estudio la produccion de neutrones frios, considerando como parametro importante la resistencia a la radiacion, en distintos materiales moderadores hidrogenados para el diseno conceptual de una fuente fria de neutrones para el reactor RA-3.Dentro de los materiales estudiados el mesitileno es el que reduce el riesgo de liberacion espontanea de energia quimica.Se generaron bibliotecas de hidrogeno en mesitileno utilizando el sistema de procesamiento de datos nucleares NJOY y se compararon las secciones eficaces resultantes con datos experimentales.Se encontro un buen acuerdo entre valores calculados y experimentales, en aquellos casos en los que existen datos disponibles.Con estas bibliotecas validadas se prev. iniciar los calculos con la geometria del reactor RA-3
