Abstract
EN UN REACTOR NUCLEAR DE AGUA EN EBULLICION SE FORMA, EN EL INTERIOR DE LA CARCASA DEL ELEMENTO COMBUSTIBLE DEL REACTOR NUCLEAR, UN CANAL DE FLUJO SECUNDARIO POR CADA CUATRO VARILLAS DE COMBUSTIBLE PARALELAS A LAS PAREDES DE LA CARCASA, EN LAS QUE SE HAN DISPUESTO AL MENOS DOS, PREFERENTEMENTE CUATRO PALAS, QUE SE ESTRECHAN EN DIRECCION DEL FLUJO DEL REFRIGERANTE Y EN EL ESPACIO SE CURVAN, DE TAL FORMA QUE EN EL FLUJO VERTICAL DEL LIQUIDO REFRIGERANTE, GENERAN UNA TORSION. POR ELLO, ES POSIBLE UN RENDIMIENTO RELATIVAMENTE ALTO DEL ELEMENTO COMBUSTIBLE DEL REACTOR NUCLEAR.
