Risk Assessment And Analysis

Power plant relay protection setting value of the hidden harm causes of relay protection device is not correct, safe and stable operation of the power plant. In this paper, from the angle of the safe operation of power plant, the hidden danger to plant with the protection setting is studied and then the risk evaluation method of power plant relay protection setting values of hidden trouble is proposed. From the power plant relay protection setting value considering two aspects of probability and consequences of potential outbreak of different values, value potential risk is considered, and of a certain power plant in Hubei was made the risk assessment and analysis, in order to verify the theoretical rationality and accuracy.

Coastal waters are polluted by heavy metals to varying degrees, posing potential risks to marine ecology and human health. In May 2006, the pollution levels, sources, and ecological risks of heavy metals (Cu, Pb, Zn, Cd, Hg, and As) in seawater, surface sediments, and living organisms were studied in Jiuzhen Bay in Fujian, China. This study identified Hg (0.26–0.72 µg/L) and As (20.3–31.5 µg/L) pollution in the seawater of Jiuzhen Bay. In sediments, heavy Pb pollution (946 µg/g dw) was only detected at one station at a level posing very serious potential risk, while Hg pollution (0.052–0.087 µg/g dw) was observed at three stations at a level posing serious potential risk. No heavy metal pollution was detected in sediments at other stations. The concentrations of five heavy metals (Cu, Zn, As, Cd, and Pb) exceeded the corresponding National Quality Standards for oysters, indicating heavy pollution, based on an ecological risk assessment. In clams, two heavy metals (Pb and As) exceeded the standards, indicating light pollution, based on an ecological risk assessment. No heavy metal pollution was found in fish or shrimps. The heavy metals in the seawater and sediments of Jiuzhen Bay are mainly derived from the river discharges of Luxi and Wujiang Rivers although sewage discharge along the coast of Jiuzhen Bay is another source of heavy metal pollution at some stations. Given the pollution of Pb, Hg, and As in seawater and sediments at some stations within the bay, the potential risks of Pb, Hg, and As in living organisms to both the marine ecology and human health deserve increased attention.

Potential Applications

The material presents an analysis of a potential risk assessment of operating military bridge facilities. Three types of steel military bridges were analysed: assembled bridges, vehicle-launched bridges and low-level bridges. The material presents an original method of a fatigue risk factor analysis. Furthermore, the author presents potential applications of the AHP method to determine weights for risk factors under analysis. It is assumed that at the further stage of research a thorough identification and quantification of other risk factors will be conducted.
