    摘要： A fuel assembly has part length and full length fuel rods, and a pair of large-diameter water rods which occupy an area which can accommodate 7 fuel rods. Natural uranium regions are provided in the upper and lower end portions of the effective fuel zone of the fuel assembly. An intermediate region between these upper and lower natural uranium regions provides an enriched uranium region which has three axial sections: an upper section, a middle section and a lower section. The middle section has the highest average enrichment, the lower section has the medium average enrichment and the upper section has the smallest average enrichment. The difference in the average enrichment between the middle section and the lower section is smaller than that between the middle section and the upper section. The upper section has a lower concentration of burnable poison than other sections of the enriched uranium region. According to this arrangement, a greater burn-up degree of the fuel assembly can be achieved with minimal increment of the average enrichment, while preserving sufficiently large safety margin such as the thermal margin of the reactor and the reactor cold shut down margin.

    摘要翻译： 燃料组件具有部件长度和全长燃料棒，以及一对大直径水棒，其占据可容纳7个燃料棒的区域。 天然铀区设置在燃料组件的有效燃料区的上端部和下端部。 这些上部和下部天然铀区域之间的中间区域提供了具有三个轴向部分的浓缩铀区域：上部分，中间部分和下部分。 中段平均浓度最高，下段中等浓度富集，上段平均浓度最小。 中段与下段之间的平均富集差异小于中段与上段之间的平均浓度差。 上段与浓缩铀区其他部分的可燃毒物浓度较低。 根据这种布置，燃料组件的燃烧程度可以以平均富集的最小增量实现，同时保持足够大的安全裕度，例如反应堆的热裕度和反应堆的冷关闭余量。

    摘要： A fuel assembly for a boiling water reactor comprising an upper and lower tie plates, a plurality of fuel rods filled therein with a plurality of fuel pellets, a fuel bundle comprising the fuel rods retained with a plurality of spacers in spaced relation and disposed between the upper and lower tie plates, and a polygonal tube-like channel box which encloses the fuel bundle and constitutes flow paths for coolant. The fuel rods comprise long fuel rods and short fuel rods which are each shorter in the effective portion than each of the long fuel rods. The concentration of fissile material in each of the short fuel rods is lower than the mean concentration of fissile material in the cross section of the fuel bundle. In the case the fuel bundle is vertically subdivided into two regions, an upper and lower one, with the upper end of the effective portion of each of the short fuel rods as a border, the mean concentration of fissile material in the cross section of the fuel bundle in the region lower than the border is lower than that in the cross section of the fuel bundle in the region above the border.

    摘要： A period of a correlation signal from a laser Doppler velocimeter is calculated from crossing points at which a correlation function crosses over a threshold level by clipping and digitizing a Doppler burst signal, thereby enabling an accurate and real time measurement to be made of a flow velocity, even in low SNR Doppler signals. Smoothing the waveform of a correlation signal further improves measurement accuracy. When the threshold level is set to be the 1/2 value of the autocorrelation function at .tau.=0, a crossing point is precisely detected even in an uneven correlation function or small amplitude of the crosscorrelation function, thus further increasing measurement accuracy.
