A <i>Chlorella</i> strain with high growth rates under heterotrophic growth condition was isolated from a pond and identified as <i>Chlorella regularis.</i> The optimal temperature for growth was 36&deg;C and the optimal pH 6.0_??_7.0. Glucose, galactose, acetic acid, ethanol, acetaldehyde and pyruvic acid may serve as the carbon source supporting the growth under both dark and light conditions.<br> The specific growth rate &mu;max was; 0.3 hr^-1 under autotrophic condition, 0.28 hr^-1 under heterotrophic condition, and 0.45 hr^-1 under mixotrophic condition. In the dark heterotrophic culture, the yield of the cells to glucose was 0.5_??_0.6, that to acetic acid 0.48, and that to ethanol 0.66. When dark heterotrophic cells were cultured under mixotrophic condition, the yield to glucose increased to 0.82, that to acetic acid to 0.85 and to ethanol to 0.91.<br> The protein and chlorophyll contents of the cells in autotrophic culture were approximately, 60% and 4Y., respectively. These contents of the cells in dark heterotrophic culture changed in accordance with the growth phase. The protein of the cells reached to, approximately, 60% and the chlorophyll to 2% in stationary phase of growth, although the cells were maintained even in the dark.

When heat-transfer tube failure occurred in SG of LMFBR and the steam leak rate is medium (some 10s g/s-some kg/s), overheating tube rupture would be caused due to the accelerated high-temperature creep in the heat transfer tubes surrounded by the high temperature products of sodium-water reaction (SWR). However, the detailed analysis code to analyze this phenomenon is not established. Adopting a Computational Fluid Dynamics (CFD) code would be a promising candidate for that perpose. At first in developing the analysis tool using a CFD code, STAR-CCM+ and LHM (Locally Homogeneous Multi-phase) model was adapted considering the appropriateness to SWR and the merits of homogeneous model, that is, the light load of computing resources and the minimum usage of models whose applicability is remained in argument. In the second step, a concept of interfacial area density was introduced to the submerged jet analysis. Furthermore, a sodium-water reaction model was added as an external function of the CDF code. A trial calculation was made to the basic SWR experimental data obtained by Hobbes et al. The analysis of the temperature profile formed in the jet region showed a good agreement with the experiment by properly choosing parameters such as Lewis number and the heat transfer coefficient on the sodium droplet. No marked difference was seen between the two-dimensional analysis and the three-dimensional analysis.
