挿着固定するのが容易である。 In the figure, numeral 10 is a magnetic ring on which the fuel rod number is recorded as a magnetic signal. This ring 10 is inserted into a predetermined position of a plenum portion P within the cladding tube 1. In this case, the ring 10 may have a cylindrical shape, but as shown in FIGS. 2 and 3, a portion of the cylindrical shape may be cut away in the axial direction. As shown in FIG. 3, such a partially cut out part is easily inserted and fixed into the plenum part P because it is subjected to a force that spreads outward.

In this step, the fuel rod number is recorded in advance as a magnetic signal, and then the fuel rod is assembled with the ring 10 attached to the plenum portion P within the cladding tube 1. For the fuel rods assembled in this way, the fuel rod number magnetically recorded on the ring 10 can be easily read from the outside of the cladding tube 1 using a magnetic reader (not shown) when necessary. be able to. In addition, the ring 10 can remain sealed inside the fuel rod and does not need to be taken out, so there is no need for conventional post-processing such as removing a label seal or cleaning the fuel rod. Since the ring 10 with recorded information is housed and nothing is attached to the outer surface of the cladding tube 1, handling is extremely easy.
