摘要： A spacer is disclosed which contains an Inconel grid and a Zircaloy surrounding band. The Inconel grid can be fabricated from the extremely thin and highly elastic spring metal. The grid comprising cells with paired inwardly bent vertical spring legs (24), (26) with cantilevered and rod encircling upper and lower arm pairs (28), (30). The spring legs (24), (26) extend at spaced apart locations between the upper and lower arm pairs (28), (30) and have a medial spring rod contacting portion (25), (27) for biasing the rods into stops (45), (46), (47), (48) on the rod encircling arm pairs (28), (30). The springs at the upper and lower ends are provided with spring dimple stops (34), (35), (36), (37) to prevent over stressing of the spring during assembly or handling. The rod encircling arm pairs (28), (30) have different length to provide upon assembling of the short and the long leg of adjacent cell arms an overlaping configuration. The gaps between the arm ends (50), (51) are offset. Spot welding of the two pairs of arms forms a structurally rigit unit. An all Zircaloy band is disclosed for surrounding the Inconel grid cells. Apertures in the band at the corners, allow to key the grid to the band of the Inconel.

摘要： Apparatus is provided for simulating a nuclear fuel rod bundle transient condition and includes a vessel (10) for containing a coolant, a pair of heating elements (18,20) disposed in the vessel (10) and a power supply (24,28) for supplying power over time to each of the heating elements (18,20). The power supply is independently controlled whereby a variable supply of power over time to each heating element is provided, thus simulating the variation in power output and axial flux shape in a nuclear fuel bundle as a function of time.

摘要： In a boiling water reactor having discrete bundles of fuel rods (65) confined within channel enclosed fuel assemblies, an improved fuel design of bundles of fuel rods interior of the channels is disclosed. Specifically, partial length rods (60) are utilized which extend from the bottom of the channel only part way to the top of the channel. These partial length rods (60) are shortened with respect to the remaining rods (65) and are symmetrically distributed throughout the fuel bundle with the preferred disposition being in the second row of the bundle of fuel rods from the channel wall. The symmetrical distribution of the partial length rods is at spaced apart locations one from another. The partial length rods extend from the bottom of the fuel bundle and terminate within the boiling region. During shutdown of the reactor, an improved cold shutdown margin is produced at the top of the fuel assembly due to the improved moderator-to-fuel ratio and reduction in plutonium formation at the upper portion of the bundle. Rod spacers (S) and bundle tie plates (40,42) are provided with larger apertures (67) overlying the partial length rods for further channeling of the steam and reduction of two-phase pressure drop.
