This is the third part of three paper describing accidents at Fukushima Daiichi nuclear power station as analyzed in Phase 2 OECD/NEA project “Benchmark Study Accident Nuclear Power Plant” (BSAF). In this paper, we describe accident progression unit 3. Units 1 and are discussed parts series papers. BSAF project, eight organizations from five countries (CRIEPI, IAE, JAEA NRA, Japan; IRSN France;...

Recent developments in the design and manufacture of microcomputers together with improved simulation techniques make it possible to achieve the speed and accuracy required for the dynamic simulation of power systems in real time. This paper presents some experimental results and outlines new ideas on hardware architecture, mathematical algorithms and software development for this purpose. The ...

The thrust bearing, as the only part bearing axial load, is extremely important in vertical hydroelectric generating units. Its working condition directly affects safe and reliable operation of unit. However, during operation, oil film easily damaged under influence complex factors. Installation deviation a key point that can cause temperature pressure changes film, affecting force on bearing. ...
