... penetration distance for pure hydrogen axisymmetric flammable clouds, whereas in cross-flow conditions a more complex three-dimensional behavior was found, potentially opening a safety-related concerns discussed in the paper. In the axisymmetric case, Fig. 13 (bottom), increasing the hydrogen content...

... triggering the safety valve opening. The study confirmed the optimal position of the monitoring point. The results showed that the RDF is indeed sensitive to different types of flow instabilities appearing in different impellers, and that it provides efficient flow stability monitoring.

...Hiroyuki Sato; Hirofumi Ohashi; Yujiro Tazawa; Nariaki Sakaba; Yukio Tachibana The establishment of a safety evaluation method is one of the key issues for the nuclear hydrogen production demonstration since fundamental differences in the safety philosophy between nuclear plants and chemical plants...

... turbine power stations modelling safety In the light of the depletion of fossil fuel resources, alternative energy sources should be considered. The main drawback of nuclear energy hitherto has been its safety problems which lead to expensive security measures, thus adversely effecting economic...
