摘要： A stable DC power system of high-voltage and good-output performance is provided by adding a 3-phase inverter, whereby modified waveform for an output control is produced and a filter to a conventional DC power system and by bridge-rectifying. The modified sinusoidal wave such as a varied wave whose upper portion ranging from 30.degree. to 150.degree. is flat of a 1/2 cycle of the sinusoidal wave, a modified wave whose portions ranging from 30.degree. to 90.degree. and from 90.degree. to 150.degree. are linear in a 1/2 cycle of the sinusoidal wave and a modified wave whose portions ranging from 30.degree. to 90.degree. and from 210.degree. to 270.degree. are recessed so as to be symmetrical with respect to a line in the whole cycle of the sinusoidal wave are used for reducing ripples of the output voltage after the 3-phase rectification.

摘要： System and method for detecting and/or predicting in a field the leakage of nuclear reactor coolant that may occur at the pressure boundary of the primary system of a nuclear reactor. The system and method for detecting the leakage of nuclear reactor coolant uses a laser induced emission spectrum. The leakage of coolant is detected by detecting boron (B), a main component of the coolant, in corrosive products generated at the nuclear reactor pressure boundary on the basis of laser spectroscopy. An embodiment of the system for detecting leakage of nuclear reactor coolant may include a laser generator, a laser focusing lens, an emission collector, and emission spectrum analyzer.
