This link provides information about the current status of reactors around the world. It is particularly interesting showing statistics on the current number of reactors in operation and those permanently shutdown. Many of these reactors have been in operation for several years and have undergone refurbishment due to aging and obsolesce. As the facility ages, equipment in operation can become less reliable and therefore increases the risk of a nuclear event. Adding an additional safety system such as the TEGSS would help mitigate this risk.
It is recognized that the availability of power to commercial nuclear power plants is essential for safe operations and accident recovery. A Loss of Offsite Power (LOOP) event, therefore, is considered an important contributor to the total risk at nuclear power plants.
This link shows in detail the actual effects on the people and the environment in the immediate area of the meltdown.
Some 4,500 square miles – (the size of Connecticut)– was found to have radiation levels that exceeded Japan’s allowable exposure rate.
All of the land within 20 km of the destroyed nuclear power plant, an area of about 600 sq km, were declared too radioactive for human habitation.
Estimates of the total economic loss range from $250-$500 billion US
In 2012, officials stated that 159,128 people had been evicted from the exclusion zones, losing their homes and virtually all their possessions.
Radioactive cesium has taken up residence in the exclusion zone, replacing the human inhabitants. It will maintain ownership of the exclusion zone for centuries.
The ecosystem is becoming contaminated by radioactive cesium, it quickly spreads everywhere, contaminating water, soil, plants and animals. It has been detected in a large range of Japanese food, including spinach, tea leaves, milk, beef, and freshwater fish up to 320 kms from Fukushima.
Efforts to clean up highly contaminated areas are generally failing because melting snow and rainwater run off from the contaminated hills and return to recontaminate homes and land.
In addition to its effects on land, the Fukushima disaster produced the largest discharge of radioactive material into the ocean in history. Fifteen months after 733,000 curies of radioactive cesium were pumped into the Pacific, 56 percent of all fish catches off Japan were found to be contaminated with it.
Every day, ten tons of seawater is poured upon each of the melted cores; the water becomes intensely radioactive and then rapidly leaks out of the containment into the adjacent turbine building. Fifty million gallons of intensely radioactive water have already been collected and stored on site. Thousands of additional radioactive gallons continue to accumulate daily, and the pipe system connecting the storage tanks remains at risk, should another large earth quake strike the area.
The Fukushima-Daïchi nuclear power plant accident in March 2011 was the first occurrence showing that an extreme natural event, that generated stress levels far beyond nuclear power plant design, could lead to a core meltdown accident. It also showed how the massive destruction of a site and of the surrounding infrastructures could delay and complicate all accident management operations with a Loss of Offsite Power.
