Resumen
La producción de hidrógeno en un reactor nuclear, consecuencia de la descomposición radiolítica del agua y de la oxidación de los materiales estructurales, es un dato de gran interés en estudio de accidentes por pérdida de refrigerante (LOCA). La concentración de dicho gas no debe exceder el 4% en volumen, límite de seguridad para la formación de una mezcla explosiva con el oxígeno del aire.
At nuclear accidents in reactors by loss of refrigerating (LOCA), it’s very important the fact of hydrogen production by water radiolitic decomposition and structurals materials oxidation. The hydrogen concentration mustn't be over 4%, that’s the security bound to form an explosive mixture with the air oxygen. This study has brought out the hydrogen radiolitics profits (at all its isotopes) in mixing of H20 and D2O. At this the profits shows a time of 21 ±3 days for the concentration come to the dangerous bound o f 4%.
