Abstract

Caja en T superior del aspersor del núcleo, para fijar a la vasija del reactor. Ensamblaje (32) de caja en T para facilitar la fijación sin soldaduras de una línea (18, 20) de aspersión del núcleo al extremo (42) de seguridad de la tobera de aspersión del núcleo, que incluye una carcasa (34) de la caja en T, una cuña (50) cruciforme y un perno (52) de tracción. La carcasa (34) T está configurada para situarse de tal forma que un primer extremo (40) se sitúe en el interior de una tobera (40) de aspersión del núcleo y trabe el extremo (42) de seguridad de la tobera de aspersión del núcleo. Los otros dos extremos (36, 38) están sustancialmente alineados y se acoplan con las tuberías (18, 20) del colector de la línea de aspersión del núcleo. La carcasa (34) también incluye una abertura (64) de la cubierta para recibir una placa (66) de la cubierta de la caja en T.
