Various reasons for NPP Road Plan Continues

Kamis, 28 April 2011

I am worried one day when finally there was no other option to provide electricity for the community than to include nuclear power plants ... But fears of radiation from the explosion of hydrogen at three nuclear reactors that have been horrendous Fukushima world has not ended just let alone Japanese authorities announced that the level of radioactive iodine in the sea near Fukushima nuclear power plant 1250 times above the safe limit.
Iodine isotopes are elements that are produced in the nucleus of uranium fission in a nuclear reactor.
Iodine can be spread easily to the environment because iodine is when the hot gas.
However, because the whole short iodine only eight days, the Japanese authorities alleviate these concerns by asserting that the radiation from the element iodine is no longer released after eight days at risk.
Fukushima case has made a number of nongovernmental organizations (NGOs) in Indonesia returned shout environment rejection of nuclear power plan and asserted that any discourse about nuclear power plant should be closed.
In the midst of this conflict, the Head of the National Nuclear Energy Agency (Batan) Hudi Hastowo Dr. maintain that the construction of nuclear power plants can not be avoided.
He chose not to respond to say much protest from NGOs and the only notice to the opponents of nuclear power plants do not make people fear with excessive negative stories about nuclear power because it is not easy to restore public confidence.
"I worry that one day when finally there are no other options to provide electricity for the community than to include nuclear power as one energy source of support, do not have any readiness even community acceptance," he said.
He pointed out that China still feel lack of energy when the nation was so "greedy" energy and use all sources of energy, both fossil energy and renewable energy to sustain economic growth sped include using various types of nuclear power plants.
10 Year AgainChairman of the Supervisory Board Concerned Citizens Energy and Environment (MPEL) Sutaryo Supadi confirms Indonesia's future development not possible without nuclear power.
"Do not just look at this. Compute the next 10 years, how much electricity demand for the industrial sector at that time. Energy is abundant but still lack, "he said.
He cited the current power capacity reached 40 thousand megawatts (MW) but in order to sustain development growth of six percent per year, electricity capacity should be increased by seven percent per year.
Thus, he said, required an additional 40 thousand megawatts more than 40 thousand MW of capacity currently available in the next 10 years.
"Where did this energy needs must be supplied while diminishing reserves of fossil energy and alternative energy are too small scale?" He said.
The period of 10 years was not too long when compared with the preparation of nuclear power plant that also eat the years, he said.
He reminded the plan to build 10 thousand MW power plant using coal has been five years passed, only one generator is realized.
Sutaryo nuclear expert who also is mentioned in terms of price, although the cost of construction investment and a big nuclear power plant technology, ranging between 1350-1750 U.S. dollars per kilowatt (KW) or more than Rp20 trillion for the capacity of 1,000 MW, the fuel required is very small and long expiration time, then counts its economical become quite cheap.
"Once the plant is built, this plant was first filled only by the 75 tons of uranium that period of his life up to 18 months. Subsequent charging only one-third 25 tons every 18 months and so on up to 40 years, "he said.
He compared with coal power plant that needs three million tonnes of coal per year for the same capacity of 1,000 MW, yet plus transportation costs to haul millions of tons of coal from the mine site outside of Java to a power plant in Java.
Members of the National Energy Board (DEN), Dr. Herman Agustiawan added it was clear that the price of nuclear electricity is very cheap compared to other power stations.
If a power plant with a capacity of 1,000 MW needs about 3.5 million tons of coal per year, the coal price 70 dollars per ton, meaning the cost for coal of about Rp2, 25 trillion per year. This amount is quite expensive let alone the price of China's current power plant investments of at least 1.4 million dollars per MW, Herman said.
Meanwhile, oil-fired power plants require 10 million barrels of diesel for each electrical generating capacity of 1,000 megawatt (MWe) annually or in need of 64 billion cubic feet of natural gas for the same capacity per year.
According to Herman, to use as fuel for nuclear power plants, electricity production cost PLN is guaranteed to be low because in addition to nuclear power plants should be built on a large scale above 1,000 MW, "lifetime" fuel (uranium) long, the price of uranium is also stable and cheaper than prices of coal and others.
The price of a gram of uranium, according to Herman, comparable to the price of 1.6 tonnes of coal.
He pointed out that South Korea has 22 nuclear power units for melistriki citizens who are only 40 million inhabitants that was sold cheap electricity price is about 4 U.S. cents per kilowatt hour (KWH).
"Why is the price of electricity produced by PLN expensive? Because in addition to small capacity, PLN also use a variety of plants, not only coal power plant, but also there are diesel, gas, also from hydroelectric (hydropower), to geothermal, "he said.
He asserted that the electricity price that seemed cheap in Indonesia due to the electricity subsidy is too large and can be consequential on the state budget deficit.
If PLN began using multiple units of nuclear power plants, electricity prices will be sucked all the nuclear power plant to be cheap, like Korea, said Herman.
Another advantage nuclear power plant, a stable electric power is needed by industry sector and is a clean energy.
Avoid carbonNPP also prevented the release of 482 million tons of carbon in the form of CO2, 15 million tons of SO2 gas and 8 million tonnes of nox gas into the air in a year, said Sutaryo.
That figure is the example calculations in 1995 where the NPP has been to avoid burning fossil fuels to 750 million tons of coal or 5.5 trillion cubic feet of natural gas or 620 million barrels of oil in that year.
Coal-fired power plant that produces one million kwh electricity, he said, releasing carbon into the air up to 230 tons or 190 tons of carbon emissions from petroleum-fueled power plant, or 150 tons of natural gas power plant.
He cited France, most countries in Europe which has 59 nuclear power plants, with the contribution of electricity to 80 percent, its CO2 emissions per gigawatt hours (GWH), electricity can be suppressed to be 93 tons.
Belgium with seven nuclear power plant CO2 emissions to 337 tons, and Spain with eight nuclear power plants to be 483 tonnes of CO2 per GWH.
Netherlands with one nuclear power plant emits 602 tons of CO2 and Denmark that has no nuclear power plant carbon emissions of 869 tonnes per gigawatt hour of electricity generated.
Currently about 30 countries have a total of 438 nuclear power reactors with a total capacity of 371,016 MWe, including 103 nuclear plants in the U.S., 59 in France, 55 in Japan, 31 in Russia, 22 in South Korea, 19 in Britain, 18 in Canada, 17 in Germany, 17 in India, 15 in Ukraine, 11 units in China, and others.
Meanwhile, Kabiro Legal Cooperation and Public Relations of Batan Dr. Ferhat Aziz said the contribution of nuclear power plants on global warming is the smallest compared to other power plant, which is only 3-24 grams of CO2 equivalent per KWH.
Compare with coal that reach eg. 950-1250 g CO2 / kwh, oil eg. 700-800 g CO2 / kwh or CO2 gas eg. 360-575 GB / KWH, he said.
Even if it contributes to global warming compared with other alternative energies such as solar energy, water energy and wind energy, nuclear energy also remains the smallest contribution, he said.
Solar energy contribution to global warming reached eg. 43-73 g CO2 / kwh, water energy eg. 1-34 g CO2 / kwh and wind energy eg. 80-30 g CO2 / kwh.(D009/B009)
