Short and Long Term Effects after the explosion Pt 2
What happened at Chernobyl
Implementation Plan For Wind Power
1. Attract wind power investment
With the largest and most abundant renewable energy resource a new Wind Farm could be a great way of saving money. •improving network connections
streamlining the planning process
creating a supportive regulatory environment
promoting investment opportunities in NSW
promoting new job opportunity.
2. Build community support:
•implementing the planning guidelines for wind energy projects
•engaging with the community early and effectively on renewable energy projects
•supporting community-owned renewable energy projects
•arming consumers with better information
•supporting renewable energy technologies through the establishment of the Renewable Energy Advocate.
3. Attract and grow wind power expertise:
We will attract and grow expertise in renewable energy technologies by:
•creating renewable energy hubs
•continuing to lead on research and innovation
•facilitating partnerships between industry, government and research organisations
•supporting the commercialisation of renewable technologies.
4. Start Building:
After we have got enough money, permission, and support we can start building.

On April 26, 1986, a major accident occurred at Unit 4 of the nuclear power station at Chernobyl, Ukraine, during the reign of the Soviet Union.
The operating crew had planned to test the turbines, they were testing to see whether the turbines could produce enough energy to keep the pumps running in case there was an emergency.
To conduct the test they purposely switched the safety systems so it would not interfere during the test. The plan did not go the way the hoped, and the power level plummeted to less than 1 percent. The workers then had to slowly increase the power. Then after 20 seconds their was an unexpected power surge. The reactor's emergency shutdown failed. One of the workers was taking out to many of the cooling rods so the reactor cooled down too much, and the other worker was putting too much water in.
The reactor's fuel elements ruptured, and a few seconds later the was a devastating explosion. A 1000 tonne sealing cap that was on top of the reactor was blown completely off. 31 fire fighters were known to have died trying to put out the fire. From April 27 to the 5th of May, more than 30 military helicopter flew over the burning reactor. While all this was happening the Soviet Union were keeping the most devastating nuclear disaster in history hushed up.
After the explosion a large sarcophagus was put around what was left of reactor 4, they thought they could keep the rest of the radioactive material under the concrete sarcophagus. By November 1986 they finished building the sarcophagus. The sarcophagus was designed with a lifetime of only 20 to 30 years in mind. The greatest problem is a lack of stability: it was hastily constructed, and corrosion of supporting beams threaten the integrity of the entire structure. Water is leaking through the sarcophagus via holes in its roof, becomes radioactively contaminated, then seeps through the floor of the reactor into the soil below.
Scientists predict that the next nuclear catastrophe in the scale of Chernobyl will be in Chernobyl itself, due to the fragile status of its protective shield.

How far did the radiation travel?
The radiation spread all across the world, even reaching Canada and the United States. The places were most of the radiation was detected, was at Ukraine, Russia, and Belarus. However there were detections of low fall-out at a nuclear plant in Sweden.The City of Pripyat was evacuated, and abandoned. People left many belongings as at the time they believed they were being evacuated only as a temporary measure. Radiation levels have dropped considerably. Some people are even sneaking into the abandoned city, to catch a glimpse of the place they spent their childhood
Here is a picture of the abandoned town of Prypiat
Long term effects
Some health professionals expect an outbreak of radiation-related illnesses in the next few decades in Ukraine.
According to the National Commission of Radiation Protection, the level of radionuclide exceeds the norm in 60 Ukrainian towns and villages. The long-lasting cesium and strontium locked up in the forests and soil pose potential threats to the health of the local people. birth defects due to lingering radiation and a severe mistrust of nuclear power by many of the general public across the world.
Due to their relatively high biological availability, cesium and strontium, which get into the body with food, may provoke gastric and kidney cancer, cardiovascular diseases and mental problems.
The nation's health is deteriorating," Mykhailo Kurik, director of the Ukrainian Institute of Ecology, told Xinhua, adding that the nature and environment were damaged even more severely than humans.
"Just after the accident, a huge quantity of radionuclide, including the burning particles, which are extremely dangerous for the environment, were released. These isotopes have very long half-lives, so Ukraine will feel the devastating effects of the catastrophe for decades," Kurik said.
Short term effects:
deadly radiation poisoning in the surrounding area and nuclear fallout affecting anywhere downwind of the disaster. Even reaching other countries.
135,000 people had to be evacutedfrom the area if they were within a 20 mile radius. longer term effects were the rendering of the surrounding land uninhabitable.
The status of the exclusion zone in Chernobyl is stable, as the radiation levels have died down.
An alternative to Nuclear Power
This was one of my resources that i used.
According to this table, Wind Turbines is a renewable source of energy and is clean and cheap aswell. It is not dangerous. It is also cheaper to make than coal power and Nuclear energy.
