Wave power plant

This prototype wave-power plant on the Scottish island of Islay was constructed by building a concrete water column across a natural gully on the shoreline. Waves flowing in and out of the gully cause water in the column to move up and down. As the water moves up 5 it compresses the air above and forces it through a wide tube at the back of the water column. As the water moves down, air is drawn into the water column. 

Like wave and OTEC power plants, one of the main barriers to the increased use of tidal energy is the initial cost of building tidal-generating stations. It has been estimated that the construction of the proposed facility on the Severn River in England would have a construction cost of 15 billion.

This chapter considers the external impact of crashing aircraft, sabotage and the effect of explosive pressure wave. The external impact is considered with reference to engineering defence measures aircraft impact, otherwise, can be prevented, with variable degrees of effectiveness, by provisions such as by modifying flight corridors or by protecting the nuclear power plant with special forces, etc. 

At present, no other nuclear power plants are being sold. However, another wave of consolidation is possible, especially if and when additional states move forward with deregulation. For example, Entergy s Hintz (2002, pg. 42) has stated that we are still talking to the utilities that own one or two nuclear plants, to pave the way for further acquisitions. 

RO and hybrid solar photovoltaic-wind power systems have been also designed and implemented (Houcine et al., 1999 Weiner et al., 2001 Mohamed et al., 2006). Recently, Folley et al. (2008) proposed a combined wave-power and RO desalination plant in which seawater can be directly... 

For some coastal locations the effects of wind waves are the dominant consideration in relation to flooding. When this is the case, special care should be taken in selecting the appropriate input characteristics for storms to obtain the maximum effects at the nuclear power plant. Under this condition a lower than maximum storm surge may result however, the overall flooding would be maximized. 

The waves generated directly by the action of the wind on transition water and shallow water are also evaluated independently from deep water waves. After deep water waves have travelled into shallow water, they dissipate part of their energy and they may be reduced to such a height as not to represent the critical wave at the site. On the basis of an appropriate aUgnment of the critical fetch to the nuclear power plant site both deep water and shallow water waves should therefore be evaluated. 

A tsunami is a train of water waves generated by impulsive disturbances of the water surface due to non-meteorological but geophysical phenomena such as submarine earthquakes, volcanic eruptions, submarine slumps and landslides or ice falls into a body of water. The severity of the waves at the nuclear power plant will depend on the characteristics of the seabed movement, the location of the plant (whether it is near a fjord or bay) and the direction of movement with respect to the plant, and the response of the near shore waters to the tsunami waves. Depending on its location, the site might be subjected to damaging waves. 

The purpose of the matrix is to help you prioritize hazards for corrective aetion. The categorization of hazards is based on severity and likelihood. Some hazards may be very likely to occur but of very minor consequences. One example is the minute release of nitrogen gas from a flapper valve into a well-ventilated, open area. Even if release is frequent, the severity of the hazard is low because the quantities are so low. However, an explosion at a commercial nuclear power plant may be remote (but obviously not impossible, as demonstrated by Chernobyl, or the remote possibility of an earthquake creating a tsunami wave hits a nuclear power plant and causes a meltdown as demonstrated by the Fukushima Daiichi nuclear disaster), but the consequences are great. These two hazards must be treated differently. Engineers too often treat all hazards equally, either overreacting or underreacting to the risk. 

Earthquakes can cause local soil failure, surface ruptures and structural damage of nuclear power plants. The most significant earthquake effects on plants or their structural components result from the seismic waves which propagate outwards in all directions from the earthquake focus. These different types of waves can cause significant ground movements up to several hundred miles from the source. The movements depend upon the intensity, sequence, duration and the frequency content of the earthquake-induced...
