| 20100104059 | RENORMALIZATION METHOD OF EXCORE DETECTOR - Disclosed is a calibration method of an excore detector used in core power monitoring of a nuclear power plant, in which a spatial weighting function (SWF), used to theoretically predict a signal of the excore detector is multiplied by a designated calibration factor to reflect characteristics of the excore detector in a calibration process. It is assumed that the SWF is the multiplication of a one-dimensional shape annealing function (SAF) and a two-dimensional SWF, and the SAF is multiplied by the calibration factor. Since the SAF is calculated in a normalized form, the multiplication of the SAF by the calibration factor to reflect characteristics of the excore detector corresponds to new normalization and thus the calibration of the SAF is referred to as renormalization The signal of the excore detector is considerably accurately predicted by multiplying the theoretically calculated SAF by the renormalization factor, and the multiplication is equally applied although the characteristics of the excore detector are highly changed. An increase in the accuracy of the excore detector in the nuclear power plant prevents unnecessary reactor trips and allows a reactor to be operated at a stable power, thus obtaining the safety of a core and raising economical efficiency. | 04-29-2010 |
| 20100071734 | Hydraulic Drive Type Partial Inter-Tube Lancing System for Cleaning Steam Generator in Nuclear Power Plant - A hydraulic drive type partial inter-tube lancing system for cleaning a steam generator in a nuclear power plant, which removes foreign matter, such as sludge, deposited around heat transfer tubes in the steam generator, is disclosed. More particularly, a hydraulic drive type partial inter-tube lancing system, which serves to clean a steam generator of a light-water reactor in a nuclear power plant by removing sludge, attached inside the steam generator, using high-pressure water, is disclosed. | 03-25-2010 |
