Abstract
Se estudia la importancia de la elección del comparador en los métodos paramétricos de análisis por activación en reactores nucleares, con énfasis en las correcciones por comportamiento
no ideal del flujo epitérmico a través del parámetro α. Se propone un nuevo método para la
determinación simultánea de este parámetro, de los flujos térmico y epitérmico y de la temperatura neutrónica. Se evalúan diferentes conjuntos de monitores y se discuten los resultados
obtenidos.
The importance of the choice of the comparator in the parametric methods of activation analysis in nuclear reactors, with emphasis in the corrections by non-ideal behaviour of the epithermal flux through the α parameter, is studied. A method for simultaneous determination of this para- meter, together with the thermal and epithermal fluxes and neutron temperature, is proposed. Different set of monitors are evaluated and the obtained results are discussed.
