THE NUCLEAR DILEMMA

"Unlike the burning of fossil fuels, nuclear power does not emit carbon dioxide. Fears about global warming have raised interest in nuclear power, with the government's chief scientific adviser Sir David King recently giving support to an expansion of nuclear on the basis that it is 'carbon-free'. He called for more investment in nuclear fusion research, and said that a new generation of existing fission technologies should be an 'option'.

But while politicians are comfortable talking about nuclear power as an option, they are less happy about it as a solution. Nuclear power does not fit easily into an environmental worldview. So long as global warming is understood as a morality tale about the evils of industrialisation there is little hope that it will inspire a nuclear renaissance......

The refusal to discuss nuclear power shows up the endless consultation and 'public participation' initiatives as the worthless exercises they really are. The Committee on Radioactive Waste Management, whose latest consultation prompted in part the most recent round of discussion, is obsessed with transparency and openness. Although more openness sounds like it could only be a good thing, in practice it leads to a devaluing of expert judgement for fear of alienating the public. Arriving at a conclusion is subordinated to a process of inclusiveness. Consultations appear to set up a self-sustaining chain reaction, with each round leading to recommendations for a further, grander round.....

It is easy to see how the nuclear industry found itself in this mess. In the 1980s and 90s the industry found that putting forward scientifically sound arguments about safety and efficiency was not sufficient to make its case, at a time when environmentalist ideas were growing. As a result of this experience NIREX shifted the focus of its research away from physics and geology toward sociology. It drew the conclusion that an expert consensus that does not carry public acceptance is practically useless, and so started to elevate inclusion over science.

Unfortunately consensus cannot be forged using the tools of inclusion - focus groups, citizen's juries or even public consultations. These forms of debate are unable to contain a real clash of ideas - unlike public political debate, they are suitable only for small-scale fudges, accommodations and adjustments. The marginalisation of science makes consensus harder still - with fewer objective facts more is left to subjective disagreement.......

The idea that nuclear power has a role to play in reducing greenhouse emissions makes sense only if we disregard the mythic dimension of the global warming discourse. Science has established that rising concentrations of greenhouse gases are likely to lead to warmer temperatures. The 'myth of global warming', however, goes beyond those facts, interpreting them through a story of man's arrogant attempts at mastery leading to a revenge of nature. There is no place for nuclear power as a hero in this myth. Rather, nuclear power is the original villain - the hi-tech, scientific, large-scale solution to economic development.

Seen in this light it is apparent that while a higher profile for global warming might give nuclear power a boost, in the end it will hold nuclear energy back. A substantial revival of nuclear power could only occur if the case was made for science and technology contributing to social progress. Without that case being made nuclear technologies will remain hedged in with restrictions, and society will be unable to realise their potential".

BUT THE NYT'S KRISTOF THINKS IT'S A GOER

Amusing that one Greenie scare (the danger of global warming) could knock off another Greenie scare (the dangers of nuclear power)

If there was one thing that used to be crystal clear to any environmentalist, it was that nuclear energy was the deadliest threat this planet faced. That's why Dick Gregory pledged at a huge anti-nuke demonstration in 1979 that he would eat no solid food until all nuclear plants in the U.S. were shut down. Mr. Gregory may be getting hungry.

But it's time for the rest of us to drop that hostility to nuclear power. It's increasingly clear that the biggest environmental threat we face is actually global warming, and that leads to a corollary: nuclear energy is green. Nuclear power, in contrast with other sources, produces no greenhouse gases. So President Bush's overall environmental policy gives me the shivers, but he's right to push ahead for nuclear energy. There haven't been any successful orders for new nuclear plants since 1973, but several proposals for new plants are now moving ahead - and that's good for the world we live in. Global energy demand will rise 60 percent over the next 25 years, according to the International Energy Agency, and nuclear power is the cleanest and best bet to fill that gap.

Solar power is a disappointment, still accounting for only about one-fifth of 1 percent of the nation's electricity and costing about five times as much as other sources. Wind is promising, for its costs have fallen 80 percent, but it suffers from one big problem: wind doesn't blow all the time. It's difficult to rely upon a source that comes and goes. In contrast, nuclear energy already makes up 20 percent of America's power, not to mention 75 percent of France's.

A sensible energy plan must encourage conservation - far more than Mr. Bush's plans do - and promote things like hybrid vehicles and hydrogen fuel cells. But for now, nuclear power is the only source that doesn't contribute to global warming and that can quickly become a mainstay of the grid.

Is it safe? No, not entirely. Three Mile Island and Chernobyl demonstrated that, and there are also risks from terrorist attacks. Then again, the world now has a half-century of experience with nuclear power plants, 440 of them around the world, and they have proved safer so far than the alternatives. America's biggest power source is now coal, which kills about 25,000 people a year through soot in the air. To put it another way, nuclear energy seems much safer than our dependency on coal, which kills more than 60 people every day. Moreover, nuclear technology has become far safer over the years. The future may belong to pebble-bed reactors, a new design that promises to be both highly efficient and incapable of a meltdown.

Radioactive wastes are a challenge. But burdening future generations with nuclear wastes in deep shafts is probably more reasonable than burdening them with a warmer world in which Manhattan is submerged under 20 feet of water......

Dispelling the myths about nuclear power: "The benefits of nuclear energy are real, while the risks are mostly hypothetical. When decisions are made concerning future sources of electric power in the United States, facts, not fear, should be the basis for appraising the nuclear industry's place in the mix, says Larry Foulke, the immediate past president of the American Nuclear Society, and H. Sterling Burnett, a senior fellow with the National Center for Policy Analysis. The events at Three Mile Island (TMI) were serious. However, rather than proving nuclear power plants are inordinately dangerous, TMI showed that redundant safety measures built into the reactor worked, say Foulke and Burnett ..."

Many people would like to be kind to others so Leftists exploit that with their nonsense about equality. Most people want a clean, green environment so Greenies exploit that by inventing all sorts of far-fetched threats to the environment. But for both, the real motive is to promote themselves as wiser and better than everyone else, truth regardless.
