Nuclear power phase-out
Encyclopedia
A nuclear power phase-out is the discontinuation of usage of nuclear power
Nuclear power
Nuclear power is the use of sustained nuclear fission to generate heat and electricity. Nuclear power plants provide about 6% of the world's energy and 13–14% of the world's electricity, with the U.S., France, and Japan together accounting for about 50% of nuclear generated electricity...

 for energy production. Often initiated because of concerns about nuclear power, phase-outs usually include shutting down nuclear power plants and looking towards renewable energy
Renewable energy
Renewable energy is energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable . About 16% of global final energy consumption comes from renewables, with 10% coming from traditional biomass, which is mainly used for heating, and 3.4% from...

an countries have debated phase-outs.

Following the March 2011 Fukushima nuclear disaster, Germany has permanently shut down eight of its reactors and pledged to close the rest by 2022. The Italians have voted overwhelmingly to keep their country non-nuclear. Switzerland and Spain have banned the construction of new reactors. Japan’s prime minster has called for a dramatic reduction in Japan’s reliance on nuclear power. Taiwan’s president did the same. Mexico has sidelined construction of 10 reactors in favor of developing natural-gas-fired plants. Belgium is considering phasing out its nuclear plants, perhaps as early as 2015.

) as the Minister of Environment, Nature Conservation and Nuclear Safety, reached an agreement with energy companies on the gradual shut down of the country's nineteen nuclear power plants and a cessation of power-generation (non-research) use of nuclear power by 2020. This was enacted as the Nuclear Exit Law. Based on the calculation of 32 years as the usual time of operation for a nuclear power plant, the agreement precisely tells how much energy a power plant is allowed to produce before being closed down.

 and Obrigheim were turned off on November 14, 2003, and May 11, 2005, respectively. The plants' dismantling is scheduled to begin in 2007.

Anti-nuclear activists criticized the agreement: they saw it more as a guarantee of years of continued operation rather than a gradual nuclear power phase-out. They argued that the grace period for the phase-out was too long and were unhappy that the ban on building new commercially used nuclear power plants did not also apply to scientifically used plants. New research plants have been put into operation since the enactment of the Nuclear Exit Law (e.g. München II). Activists were also dissatisfied that uranium enrichment plants

 of primary energy demand, which corresponds to 5% of the total electricity demand. By 2010 the German Government wants to reach 10%.

Anti-nuclear activists have argued the German government had been supportive of nuclear power by providing financial guarantees for energy providers. Also it has been pointed out, there were, as yet, no plans for the final storage of nuclear waste. By tightening safety regulations and increasing taxation, a faster end to nuclear power could have been forced. A gradual closing down of nuclear power plants had come along with concessions in questions of safety for the population with transport of nuclear waste throughout Germany. This latter point has been disagreed with by the Minister of Environment, Nature Conservation and Nuclear Safety.

Critics of a phase-out in Germany argue that the power output from the nuclear power stations will not be adequately compensated and predict an energy crisis

The next conservative government tried to cancel the phase-out, but, after protests, did not cancel it but instead decided to extend the time limit to 2010. At Barsebäck, block 1 was shut down on November 30, 1999 and block 2 on June 1, 2005.

The nuclear energy phase-out is controversial in Sweden. It is feared that Sweden will lose its international competititiveness. The energy production of the remaining nuclear power plants has been considerably increased in recent years to compensate for the turn off of Barsebäck. In 1998, the government decided to build no further hydropower plants in order to protect national water resources

Water resources are sources of water that are useful or potentially useful. Uses of water include agricultural, industrial, household, recreational and environmental activities. Virtually all of these human uses require fresh water....

. In spite of extensive efforts to create alternatives to nuclear power, such as fossil fuels, it is not likely that Sweden can complete the nuclear power phase-out by 2010. It has been estimated that nuclear power plants in operation will stay in operation until 2050.

In March 2005, an opinion poll of 1027 people showed 83% support for maintaining or increasing nuclear power. Another poll in May, of residents that lived around Barsebäck, found that 94% wanted it to stay. In June, 2005, radioactive water was detected leaking from the nuclear waste store in Forsmark, Sweden. The content of radioactive caesium in the water sampled was ten times the normal value. wikinews:Radioactive leakage at Swedish nuclear waste store. This has, however, not led to a major change in public opinion. In 2006 the Centre Party of Sweden, an opposition party that supported the phase-out, announced that it is dropping its opposition to nuclear power, at least for now, claiming that it is unrealistic to expect the phase-out in the short term. It said it will now support the opposition, which is considerably more pro-nuclear than the government.

In August 2006 three of Sweden's ten nuclear reactors were shut down due to safety concerns following an incident at Forsmark Nuclear Power Plant

In 2000 there was a vote on a Green Tax for support of solar energy. It was rejected by 67–31%. On May 18, 2003, there were two referenda: "Electricity without Nuclear," asking for a decision on a nuclear power phase-out, and "Moratorium Plus," for an extension of the earlier decided moratorium on the construction of new nuclear power plants. Both were turned down. The results were: Moratorium Plus: 41.6% Yes, 58.4% No; Electricity without Nuclear: 33.7% Yes, 66.3% No.

The program of the "Electricity without Nuclear" petition was to shut down all nuclear power stations until 2033, starting with Unit 1 and 2 of Beznau nuclear power stations, Mühleberg in 2005, Gösgen in 2009, and Leibstadt in 2014. "Moratorium Plus" was for an extension of the moratorium for another 10 years, and additionally a condition to stop the present reactors after 40 years of operation. In order to extend the 40 years by 10 more years another referendum would have to be held (at high administrative costs). The rejection of the Moratorium Plus had come to surprise to many, as opinion polls before the referendum have showed acceptance. Reasons for the rejections in both cases were seen in the worsened economic situation.

Economy

Some scholars have claimed that nuclear energy is economically disadvantageous because of the large capital costs of building a nuclear plant. The large capital costs of nuclear power plants and the associated possibility of construction delays has been a deterrent for investors because of the risk (as it has for other investments with large capital costs, such as coal plants and oil refineries). As an alternative, investors may be more inclined to choose natural gas plants, despite having a higher cost of electricity, because their small capital costs have presented less risk.

However, volatility in the price of natural gas has recently shown a greater risks to investors than it has previously, and has been making nuclear power plants (and coal power plants) more attractive than before. In the United States, this is compounded with the Energy Policy Act of 2005

Nuclear proliferation

Another argument against nuclear energy is the potential for close connection of civil and military usage (which in most countries are kept strictly separate). In manufacturing nuclear fuel rods, the fraction of the fissile uranium isotope 235 has to be increased from the natural fraction from 0.7 to 5% in order to be able to create a chain reaction (exceptions include some designs that use heavy water or graphite as the moderator, such as CANDU reactor

Opponents of nuclear power argue that it is not possible to discriminate between civil and military usage, and therefore that nuclear power contributes to the proliferation of nuclear weapons.

 do not have nuclear power plants at present, while South Africa started up its power plant long after acquiring nuclear weapons.

Design and construction of nuclear explosives based on normal reactor-grade plutonium may be difficult and unreliable, but was already done in 1962.

Much popular concern about possible weapons proliferation arises from considering the fissile materials themselves. For instance, in relation to the plutonium contained in spent fuel discharged each year from the world's commercial nuclear power reactors, it is correctly but misleadingly asserted that "only a few kilograms of plutonium are required to make a bomb". Furthermore, no nation is without enough indigenous uranium to construct a few weapons (however, that uranium would have to be enriched).

 is a substance of varying properties depending on its source. It consists of several different isotopes, including Pu-238, Pu-239, Pu-240, and Pu-241. All of these are plutonium but not all are fissile – only Pu-239 and Pu-241 can undergo fission in a normal reactor. Plutonium-239 by itself is an excellent nuclear fuel. It has also been used extensively for nuclear weapons because it has a relatively low spontaneous fission rate and a low critical mass. Consequently plutonium-239, with only a few percent of the other isotopes present, is often called "weapons-grade" plutonium. This was used in the Nagasaki bomb

s.

On the other hand, "reactor-grade" plutonium as routinely produced in all commercial nuclear power reactors, and which may be separated by reprocessing the spent fuel from them, is not the same thing at all. It contains a large proportion – up to 40% – of the heavier plutonium isotopes, especially Pu-240, due to it having remained in the reactor for a relatively long time. This is not a particular problem for re-use of the plutonium in mixed oxide (MOX) fuel for reactors, but it seriously affects the suitability of the material for nuclear weapons. Due to spontaneous fission of Pu-240, only a very low level of it is tolerable in material for making weapons. Design and construction of nuclear explosives based on normal (i.e. routinely discharged) reactor-grade plutonium would be difficult and unreliable, and has not so far been done. A nuclear device has been made however from low-burned plutonium from a Magnox nuclear reactor. It was tested in 1962. Its composition was never officially released but was evidently around 90% of fissile Pu-239. This method of production was very expensive, unreliable and easily detectable (fuel has to stay in the reactor for relatively short period (few weeks) as opposed to normal use (few years)), and with a relatively small yield. All these factors contributed to the fact that apart from the test device used in 1962 no new ones were created.

. Critics of the German policy have called it a contradiction to abandon nuclear power and build up renewable energy as both have very low CO2 emissions.

Nuclear reactors do not emit greenhouse gases or ash during normal operation; however the mining and processing of uranium involves emissions. Emissions that arise from the whole life cycle are comparable to wind energy. However, an issue of debate is that greenhouse emissions from mining, milling and enrichment may be substantially greater in the future as the world's reserves of high grade uranium are depleted, and low grade uranium is increasingly used. This view is not supported by the nuclear power industry (see next paragraph).

In a semi-technical paper, Is Nuclear Power Sustainable? and its May 2002 successor, Can Nuclear Power Provide Energy for the Future; would it solve the CO2-emission problem?, Storm van Leeuwen & Smith argued that nuclear power would eventually surpass fossil fuels in greenhouse gas emissions as high grade ore becomes scarce, putting in doubt its sustainability as part of an environmental protection plan. This paper was dismissed as false by the industry, as published results on ore extraction show 99% advantage for nuclear generation over fossil fuels on the basis of CO2 emissions. The authors greatly reduced the claims of their paper and republished it in 2005, omitting most of the numerical values they had used, but the remaining claims are still contradicted by at least some life cycle studies (e.g. Vattenfall). All this heavily disputes an article whose forecasts are alleged wrong because the basis for them is proven wrong by current data, even 3:1 in some cases. It should be noted that industry expectations are based on finding more of the high grade ores such as are currently available, whereas the claims by Storm van Leeuwen & Smith are premised on their own projections of the grades of ores available in the future. (A report commissioned by the Australian Government on the viability of nuclear energy presents an excellent review of the literature, both for and against, Storm van Leeuwan & Smith's arguments.)

Both nuclear reactors and those that burn fossil fuels raise the temperature of water used to cool them, which can pose a health hazard for aquatic life in certain eco systems. This can include species of fish already near extinction as a consequence of hydropower and other human activities. Such difficulties can be greatly reduced by using cooling tower

This is in sharp contrast with arsenic and other chemicals that are stable and will exist forever and are released burning coal.

They point out the natural example of Oklo

According to antinuclear activists, leakages of radioactive contamination put the safety of NPPs in general into question. It is feared that radiation release is a health hazard. To counter these concerns all nuclear operators are obliged to measure radiation on and around their sites as well as reporting all particles and radiation they emit. This has to be attested by an independent audit office. This practice is more or less the same in all countries that are members of IAEA.

That is a bit more than for wind which is rated at 0.15 euro cents per kWh, but considerably less than for coal which is at 4 to 7 euro cents per kWh, oil which is 3 to 5 euro cents per kWh, gas which is 1 to 2 euro cents per kWh and biomass which is at 1 euro cents per kWh. In other European countries it is more or less the same.

The quoted cost of many renewable generation sources would be increased if it included provision of necessary back-up power sources to cover periods when wind, sun, waves, etc. are weak and not producing power. It has been calculated that wind power

, one of the major hopes for proponents of the phase-out, costs three times as much as average electricity in Germany.

While in many countries nuclear power is unpopular, in times of rising prices for fossil fuels, arguments for nuclear power come up again (compare ).

Nuclear power
Nuclear power is the use of sustained nuclear fission to generate heat and electricity. Nuclear power plants provide about 6% of the world's energy and 13–14% of the world's electricity, with the U.S., France, and Japan together accounting for about 50% of nuclear generated electricity...

Proponents of nuclear power also believe that the Chernobyl accident was unique and occurred only because of poor design—especially the lack of full containment buildings—combined with unauthorized tests. They point out that no such accidents have occurred in Western reactors, which are now by far the most common design. A commonly cited example is the Three Mile Island accident, which did not release significant amounts of radioactive particles despite a nuclear meltdown
