The Pros and Cons of Nuclear Power
Since the disaster at the Fukushima nuclear power plant in Japan in 2011, a debate has been raging (1) the future of atomic energy. Consequently, the safety risks have been well publicized in the global media. But do the risks outweigh the damage that could be done to the planet because of our ongoing addiction to fossil fuels?
Even environmentalists don’t have the answer. They are split over nuclear (2) , and its pros and cons. Some say it is neither safe nor economical because it produces potentially (3) radioactive waste, and reactors are so costly to build. However, others believe nuclear energy is a necessary evil. They say we should continue using it until (4) energy sources, like wind turbines and solar panels, can meet global demand. Supporters also argue that nuclear energy helps cut down on carbon emissions from fossil fuels such as coal and natural gas, which are linked to global warming and pollute the environment. They say this is because nuclear reactors produce a tiny fraction of the carbon dioxide generated by burning coal.
But perhaps the biggest hurdle for atomic energy to overcome is its image problem. Despite industry claims of a strong safety record, critics remain unconvinced because each reactor annually produces up to 30 tons of nuclear waste, which can continue to be radioactive and hazardous for thousands of years. Furthermore, the Chernobyl disaster in 1986 left the public with vivid images of the impact of a nuclear meltdown, including deformed babies, mutated vegetables, and abandoned towns.
While nuclear reactors may continue to be installed in some countries for decades to come, after Fukushima others have decided to rethink their energy policies. For example, the German government has revealed plans for a “green” renewable energy plan, even though it has relied on nuclear power for up to 23 percent of its consumption in the past. It has been announced that all seventeen nuclear power plants would be phased out by 2022. The policy will also promote energy-saving measures encouraging people to insulate their homes, recycle, and reduce waste. Experts argue it could be a risky strategy because Germany doesn’t have natural gas or oil supplies, and coal supplies have been depleted.
Meanwhile, in Brazil, there is just one nuclear plant at Angra dos Reis. Nuclear power represents only three per cent of Brazil’s energy production. After sharp oil price rises in the 1970s, the country’s leaders anticipated future energy supply problems. So they concentrated on developing alternative energy sources including biofuel, hydroelectric schemes, and wind power.
This approach seems to be working because by May
2012 plans to build more nuclear reactors were shelved by Brazilian officials. The move was welcomed
by environmental lobby groups, which had feared a
potential ecological catastrophe in case of an accident. If a big country like Brazil, which is the tenth
largest energy consumer in the world, can survive and
improve its economy without much nuclear power,
maybe others can do so, too.
According to the sentence above is correct in relation to the verbs, EXCEPT:
A Brief and Simplified Description of Papermaking
The paper we use today is created from individual wood fibers that are first suspended in water and then pressed and dried into sheets. The process of converting the wood to a suspension of wood fibers in water is known as pulp making, while the manufacture of the dried and pressed sheets of paper is formally termed papermaking. The process of making paper has undergone a steady evolution, and larger and more sophisticated equipment and better technology continue to improve it.
The Wood yard and Wood rooms
The process at Androscogging began with receiving wood in the form of chips or of logs 4 or 8 feet in length. From 6 AM to 10 PM a steady stream of trucks and railroad cars were weighted and unloaded. About 40 percent were suplied by independents who were paid by weight their logs. The mill also received wood chips from lumber mills in the area. The chips and logs were stored in mammoth piles with separate piles for wood of different species (such as pine, spruce, hemlock).
When needed, logs were floated in flumes......(1).....the wood yard.....(2).....one of the mill’s three wood rooms. There, bark was rubbed......(3)........in long, ribbed debarking drums by tumbling the logs against one another. The logs then fell into a chipper;......(4)......seconds a large log was reduced to a pile of chips approximately 1 inch by 1 inch by 1/4 inch.
The chips were stored in silos. There were separate silos for softwoods (spruce, fir, hemlock, and pine) and hardwoods (maple, oak, beech, and birch). This separate and temporary storage of chips permitted the controlled mixing of chips into the precise recipe for the grade of paper being produced.
The wood chips were then sorted through large, flat vibrating screens. Oversized chips were rechipped, and ones that were too small were collected for burning in the power house. (The mill provided approximately 20 percent of all its own steam and electricity needs from burning waste. An additional 50 percent of total electricity needs was produced by harnessing the river for hydroelectric power.)
Once drawn from the silo into the digesters, there was no stopping the flow of chips into paper.
Pulpmaking
The pulp made at Androscoggin was of two types: Kraft pulp (produced chemically) and ground wood pulp (produced mechanically). Kraft pulp was far more important to the high quality white papers produced at Androscoggin, accounting for 80 percent of all the pulp used. Kraft pulp makes strong paper. (Kraft is German for strength. A German invented the Kraft pulp process in 1884.) A paper’s strength generally comes from the overlap and binding of long fibers of softwood; only chemically was it initially possible to separate long wood fibers for suspension in water. Hardwood fibers are generally smaller and thinner and help smooth the paper and make it less porous.
The ground wood pulping process was simpler and less expensive than the Kraft process. It took high quality spruce and fir logs and pressed them continuously against a revolving stone that broke apart the wood’s fibers. The fibers, however, were smaller than those produced by the Kraft process and, although used to make newsprint, were useful at Androscoggin in providing “fill” for the coated publication gloss papers of machines 2 and 3, as will be described later.
(A)The chemical Kraft process worked by dissolving the lignin that bonds wood fibers together. (B) It did this in a tall pressure cooker, called a digester, by “cooking” the chips in a solution of caustic soda (NaOH) and sodium sulfide (Na2S), which was termed the “white liquor.” (C)The two digesters at Androscoggin were continuous digesters; chips and liquor went into the top, were cooked together as they slowly settled down to the bottom, and were drawn off the bottom after about three hours. (D) By this time, the white liquor had changed chemically to “black liquor’’; the digested chips were then separated from this black liquor. (E)
In what was known as the “cold blow” process, the hot, pressurized chips were gradually cooled and depressurized. A “cold liquor’’ (170°F) was introduced to the bottom of the digester and served both to cool and to transport the digested chips to a diffusion washer that washed and depressurized the chips. Because so much of the lignin bonding the fibers together had been removed, the wood fiber in the chips literally fell apart at this stage.
The black liquor from the digester entered a separate four-step recovery process. Over 95 percent of the black liquor could be reconstituted as white liquor, thereby saving on chemical costs and significantly lowering pollution. The four-step process involved (1) washing the black liquor from the cooked fiber to produce weak black liquor, (2) evaporating the weak black liquor to a thicker consistency, (3) combustion of this heavy black liquor with sodium sulfate (Na2SO4 ), and redissolving the smelt, yielding a “green liquor” (sodium carbonate + sodium sulfide), and (4) adding lime, which reacted with the green liquor to produce white liquor. The last step was known as causticization.
Meanwhile, the wood-fiber pulp was purged of impurities like bark and dirt by mechanical screening and by spinning the mixture in centrifugal cleaners. The pulp was then concentrated by removing water from it so that it could be stored and bleached more economically.
By this time, depending on the type of pulp being made, it had been between 3 1/2 and 5 hours since the chips had entered the pulp mill.
All the Kraft pulp was then bleached. Bleaching took between 5 and 6 hours. It consisted of a three-step process in which (1) a mix of chlorine (Cl2 ) and chlorine dioxide (CIO2 ) was introduced to the pulp and the pulp was washed; (2) a patented mix of sodium hydroxide (NaOH), liquid oxygen, and hydrogen peroxide (H2 O2 ) was then added to the pulp and the pulp was again washed; and (3) chlorine dioxide (ClO2 ) was introduced and the pulp washed a final time. The result was like fluffy cream of wheat. By this time the pulp was nearly ready to be made into paper.
From the bleachery, the stock of pulp was held for a short time in storage (a maximum of 16 hours) and then proceeded through a series of blending operations that permitted a string of additives (for example, filler clay, resins, brighteners, alum, dyes) to be mixed into the pulp according to the recipe for the paper grade being produced. Here, too, “broke” (paper wastes from the mill itself) was recycled into the pulp. The pulp was then once again cleaned and blended into an even consistency before moving to the papermaking machine itself.
It made a difference whether the broke was of coated
or uncoated paper, and whether it was white or colored. White, uncoated paper could be recycled immediately. Colored, uncoated paper had to be rebleached.
Coated papers, because of the clays in them, could not
be reclaimed.
