North American construction is back—smaller and faster—at OPG’s Darlington
“The nuclear renaissance is real here,” said Ontario Power Generation’s Subo Sinnathamby on May 8, one year to the day after OPG secured a final investment decision to build the first of four planned BWRX-300 reactors at its Darlington nuclear power plant, and shortly after the new reactor’s foundation was lifted into place. “We got our license to construct in April and our [final investment decision] in May, and we’ve been off to the races since.”

Doppler Broadening methods have been intensively used in measuring the temperature of neutral atoms and ions in plasma diagnostics. However, since only the line-integrated emission can be measured in the experiments, the local temperature can not be found directly. To solve this problem, we first measured the spatial distribution of each spectrum by Abel inversion and then obtained the Doppler broadening at each radial position by analytically combining the spectra. The emissions are collected through five optical fibers which are located at intervals of 48 mm and inserted into the slit of a spectrometer. The dispersed output from the spectrometer is measured with a CCD camera. Since the abscissa of a CCD frame represents the spectra and the ordinate represents the spatial distribution, the Abel-inverted Doppler broadening is easily measured. By using this method, we measured the temperature distribution of neutral atoms and ions in the Hanbit device.
