Released radioactive materials from a nuclear power plant due to an accident can be transported to far regions by wind. Some models are available to predict the dispersion. This article reports some parts of the results of a research in which using one of the models, named HYSPLIT, to predict the dispersion of some isotopes of iodine and cesium released from ten nuclear power plant to the atmos...
Poor control of the nuclear steam generator (SG) water level of pressurized Water Reactor can lead to frequent reactor shutdowns. In addition, the steam generator is a highly complex, nonlinear and time-varying system and its parameters vary with operating conditions. The dynamics of a nuclear steam generator is very different according to the power levels and changes as time goes on. Therefore...
Many different methods have been presented to solve unit commitment (UC) problem in literature with different advantages and disadvantages. The need for multiple runs, huge computational burden and time, and poor convergence are some of the disadvantages, where are especially considerable in large scale systems. In this paper, a new analytical and non-iterative method is presented to solve UC p...
6.1 Best Practices in Operation & Maintenance of Hydro Power stations shall be such that by following such procedures, the downtime of individual generating Unit & Plant should be minimum. The operational reliability of the generating units of the hydro power stations shall be such that whenever the grid demands, it should be available for generation. Some of the aspects, which can be taken int...
Tarapur Atomic Power Station is a twin unit Boiling Water Reactors. The rated initial capacity of each unit was for 210 MWe. Subsequently due to Secondary Steam Generator tube leak problem, the units were de-rated to 160 MWe in the year 198485. The station has completed 36 years of successful commercial operation. TAPS reactor fuel channels are made of Zircaloy -4, material. These are used alon...
In this paper, competitiveness of nuclear power plants in comparison with fossil fuel power plants in Iran has been evaluated. For the first step, different factors affecting economic competitiveness of thermal power plants such as Investment, O&M and Fuel Costs, Discount Rate and Environmental Impacts has been studied. To analyse the effect of each parameter, screening curve method has been us...
