Abstract:
Accidental and illegal marine pollution in the Mediterranean Sea constitutes a major threat to the marine environment. Previous incidents in the Mediterranean Sea and the Arabian Gulf have resulted in environmental and economic damages to fisheries, to the tourist industry and to coastal marine ecosystems. Oil-pollution discharges in the Mediterranean Sea and Arabian Gulf from ships and sometimes the coastline power plants have been described as significant and are a cause of environmental degradation in the seas of the Middle East region. To prevent the major impact of accidental oil spills, local and regional preparedness and response plans recommend the use of computer-aided support systems based on operational oceanography and real-time ocean forecasts and real-time ocean forecasts coupled with satellites images and oil-spill models.
In this study, these models were used to predict the movement of oil spills which were caused by a hypothetical tanker accident and coastline power plants on the Levantine Basin (sub region in the Mediterranean Sea) and the Arabian Gulf. The European program (MIDSLIK) was used to simulate four oil spill accidents in the Mediterranean Sea near to the north coast of Egypt. Some of these accidents were caused by tankers and others by coastline power stations such as Abu Qir power station in Alexandria. This program incorporates the use of forecasts developed under MFS (Mediterranean forecasting system) program for the whole Mediterranean Sea and its sub-regions (Levantine Basin). It uses a modified version of Mackay’s fate algorithms for evaporation and emulsification and the dispersion algorithm of Buist and Mackay. Moreover, the American program (GNOME) was used in this study to simulate an oil spill occurred on the Iranian coastline on the Arabian Gulf after an accident in Bushehr Nuclear Power Plant after an earthquake occurred. It is also used to simulate an oil spill caused by a tanker near to Baraka Nuclear Power Plant in the United Arab Emirates. The world worst oil spills occurred since 1967 and its sources are presented in this study.
The thesis contains an analysis of oil impact on the performance of a nuclear power plant; starting from the effect on the inlet cooling water of the condenser in the secondary circuit of the reactor and ending with the effect on the primary circuit parameters and reactor power. This analysis depends on computer model of the reactor condenser which is designed by using MATLAB and SIMULINK. Moreover, a mathematical model for predicting the dynamic response of the H. B. Robinson pressurized water reactor plant (Primary circuit) is formulated and simulated by
POL YMATH software. Also this part contains an explanation of the functions of the Chemical and Volume Control System (CVCS) which is used to contain this impact. This part includes technical and operational specifications of a PWR.
from the calculations in this study, some conclusions and recommendations were concluded to help in the containment countermeasure plans to prevent the damage of oil spill accidents in the Mediterranean Sea and the Arabian Gulf in the Middle East and also to support decision maker with predictions of oil fate and dispersion.
