AbstractAbstract
[en] A method of operating a nuclear reactor having a core and coolant displacer elements arranged in the core wherein is established a reactor coolant temperature set point at which it is desired to operate said reactor and first reactor coolant teperature band limits are provided within which said set point is located and it is desired to operate said reactor characterized in that said reactor coolant displacer are moved relative to the reactor core for adjusting the volume of reactor coolant in said core as said reactor coolant temperature approaches said first band limits thereby to maintain said reactor coolant temperature near said set point and within said first band limits

AbstractAbstract
[en] In planning for the next century, the French CEA and Framatome are conducting r and d aimed at assessing the feasibility of undermoderated and spectral shift concepts. For many years to come, however, advanced French PWRS will comprise the existing N4 design, improved, possibly, by feedback of experience and developments in technology. (author)

AbstractAbstract
[en] Spectral shift, especially blueshift, in peak position of electroluminescence (EL) spectrum of Si nanocrystal (Si-nc) with respect to its photoluminescence (PL) counterpart has been often observed. Explanations for the spectral difference are different for different EL mechanisms adopted. To gain a relevant picture of the EL process, in this work, we analyze three EL mechanisms that are mainly applied nowadays, i.e., the model of defect light emission, that of band-filling, and that of Si-nc size selection by the carrier energy. Different Si-nc samples and working conditions are designed and their EL and PL emissions monitored according to the predictions of the three models. It is concluded that the observed EL is mainly of Si-nc-related origin. The experimental results are more consistent with the model of Si-nc size selection

AbstractAbstract
[en] Crystals RbUO2(NO3)3 with a touch of cations of alkali elements and ammonium with different concentration were created. Controllable shift of electronic and vibron transitions was discovered. This effect was explained by the formation of new luminescent centers. Observed temperature dependence of position of electronic quasi-lines was disclosed

AbstractAbstract
[en] Field shifts have been evaluated in neodymium by accurately measuring the isotope shift of five even-even and two odd-even isotopes and evaluating the specific mass shift using electronic X-ray as well as muonic isotope shift data. The relative change of mean square nuclear charge radii has been evaluated and results agree well with earlier values. (author)
