A reactor pressure vessel(RPV) of a boiling water reactor(BWR) typically has a generally cylindrical shape and is closed at both ends, e. g., by a bottom head and a removable top head. A core assembly is contained within the RPV and includes the core support plate, fuel assemblies, control rod blades and a top guide. A core shroud typically surrounds the core assembly and is supported by a shroud support structure. Particularly, the shroud has a generally cylindrical shape and surrounds both the core plate and the top guide.

In the monolithic type pebble bed reactor, the dimension of the reactor core diameter becomes large, and nuclear control for a large-sized reactor having a large output scale is insufficient in a cooled state using only control elements(control rod, boron sphere) inserted into the reflector region. Furthermore, a reactor core control rod, which is forcibly inserted directly into the reactor core, is required in addition to the control elements inserted into the reflector region by gravity drop only. Moreover, cases have been reported that fuel spheres are broken if the control rod is inserted forcibly into the core because the pebble reactor core is full of fuel spheres accumulated inside the reactor core, which causes a serious drawback. 1, record 5, English, - pebble%20bed%20reactor%20core

The function of the Rod Scanning Unit is to check for alpha contamination on the fuel rods, to inspect the pellet stacking inside the fuel rods, and to assess pellet-to-pellet variations in the rods. After receipt and identification of a rod tray, each rod is sequentially inspected. Each rod passes successively through three measuring cells : Gamma transmission cell for inspecting internal pellet stacking. Alpha counting cell for performing an alpha contamination check. Active gamma scanning cell for assessing plutonium content. 1, record 15, English, - active%20gamma%20scanning

A fuel rod for a nuclear reactor fuel assembly includes a cladding tube and a plurality of fuel pellets contained in the tube and composed of fissile material, such as uranium dioxide, having a single enrichment of U-235. At least some of the fuel pellets have an annular configuration. Some of the annular fuel pellets have an annulus of a first size, whereas other... annular fuel pellets have an annulus of a second size different from the first size. 1, record 41, English, - cladding%20tube

Dans un combustible pour réacteur à eau légère la matière fissile se présente sous forme de petits cylindres en oxyde d'uranium fritté dits «pastilles». Un certain nombre de ces pastilles est empilé dans un tube - dit tube de gainage ou gaine - scellé aux deux extrémités par des bouchons soudés afin d'isoler la matière fissile du milieu extérieur; cet ensemble forme ce qu'on appelle un crayon combustible. 1, record 41, French, - tube%20de%20gainage

The present invention relates to a fuel rod for a nuclear plant and a plenum spring arranged to be provided in a fuel rod. The fuel rod comprises a cladding tube sealed at its ends by end plugs, a plurality of fuel pellets stacked on each other inside the cladding tube such that they form a column of pellets and said plenum spring arranged to hold with a spring force the column of pellets against the lower second end of the cladding tube during operation. 1, record 43, English, - plenum

Prior art fuel elements used in nuclear reactors can be divided into two general classes--flat plate fuel elements and cylindrical rod fuel elements. A requirement for plate fuel elements is that the fuel be metallurgically bonded to the cladding. Fuel elements of this type are conventionally brazed in parallel relation between two side plates. 1, record 44, English, - plate%20fuel%20element
