Plutonium’s global problems are piling up

Plutonium’s global problems are piling up

Increasing worldwide stockpiles of surplus plutonium are becoming a political embarrassment, a worrying security risk, and a hidden extra cost to the nuclear industry.

LONDON, 22 January, 2016 − Two armed ships set off from the northwest of England this week to sail round the world to Japan on a secretive and controversial mission to collect a consignment of plutonium and transport it to the US.

The cargo of plutonium, once the most sought-after and valuable substance in the world, is one of a number of ever-growing stockpiles that are becoming an increasing financial and security embarrassment to the countries that own them.

So far, there is no commercially viable use for this toxic metal, and there is increasing fear that plutonium could fall into the hands of terrorists, or that governments could be tempted to use it to join the nuclear arms race.

All the plans to use plutonium for peaceful purposes in fast breeder and commercial reactors have so far failed to keep pace with the amounts of this highly-dangerous radioactive metal being produced by the countries that run nuclear power stations.

The small amounts of plutonium that have been used in conventional and fast breeder reactors have produced very little electricity − at startlingly high costs.

Out of harm’s way

Japan, with its 47-ton stockpile, is among the countries that once hoped to turn their plutonium into a power source, but various attempts have failed. The government, which has a firm policy of using it only for peaceful purposes, has nonetheless come under pressure to keep it out of harm’s way. Hence, the current plan to ship it to the US.

“Radiation is Good for You!” and Other Tall Tales of the Nuclear Industry

“Radiation is Good for You!” and Other Tall Tales of the Nuclear Industry

The U.S. Nuclear Regulatory Commission is considering a move to eliminate the “Linear No-Threshold” (LNT) basis of radiation protection that the U.S. has used for decades and replace it with the “radiation hormesis” theory—which holds that low doses of radioactivity are good for people.

The change is being pushed by “a group of pro-nuclear fanatics—there is really no other way to describe them,” charges the Nuclear Information and Resource Service (NIRS) based near Washington, D.C.

“If implemented, the hormesis model would result in needless death and misery,” says Michael Mariotte, NIRS president. The current U.S. requirement that nuclear plant operators reduce exposures to the public to “as low as reasonably achievable” would be “tossed out the window. Emergency planning zones would be significantly reduced or abolished entirely. Instead of being forced to spend money to limit radiation releases, nuclear utilities could pocket greater profits. In addition, adoption of the radiation model by the NRC would throw the entire government’s radiation protection rules into disarray, since other agencies, like the EPA, also rely on the LNT model.”

“If anything,” says Mariotte, “the NRC radiation standards need to be strengthened.”

The NRC has a set a deadline of November 19 for people to comment on the proposed change. The public can send comments to the U.S. government’s “regulations” website.

Comments can also be sent by regular mail to: Secretary, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001, Attention:Rulemakings and Adjudications Staff. Docket ID. Needed to be noted on any letter is the code NRC-2015-0057.

If the NRC agrees to the switch, “This would be the most significant and alarming change to U.S. federal policy on nuclear radiation,” reports the online publication Nuclear-News“The Nuclear Regulatory Commission may decide that exposure to ionizing radiation is beneficial—from nuclear bombs, nuclear power plants, depleted uranium, x-rays and Fukushima,” notes Nuclear-News.

Can U.S. Nuclear Plants Operate For 80 Years?

Can U.S. Nuclear Plants Operate For 80 Years?

The nuclear industry in the United States has been at a standstill for several decades. After an extraordinary wave of construction in the 1960s and 1970s, the nuclear industry ground to a halt. A confluence of events killed off new construction, including high interest rates, cost overruns, delays, and the Three Mile Island incident that scared the public and turned it against nuclear power.

But despite the nuclear industry’s inability to build more than a handful of new nuclear power plants since the 1980s, nuclear power still accounts for about 19 percent of electricity generation in the United States, the third largest source of electricity behind coal and natural gas.

Yet the nation’s 99 reactors are mostly nearing their retirement age. Having originally been planned for 40-year lifespans, many of the reactors would have already been forced to shut down by now, with nearly all of the rest hitting their limits at some point within the next decade. Instead, more than three-quarters of them have already received a 20-year extension, putting off their retirements until the 2030s.

But in the nuclear sector, where everything takes a long time, the 2030s are rapidly approaching. With one-fifth of the country’s electricity fleet nearing retirement, and very few nuclear power plants under construction to replace what is expected to be lost, how will the U.S. cope with the lost capacity?

“Four reactors are being built, but there’s absolutely no money and no desire to finance more plants than that. So in 20 or 30 years we’re going to have very few nuclear power plants in this country—that’s just a fact,” the former Chairman of the Nuclear Regulatory Commission, Gregory Jaczko, said in a 2013 interview.

Renewable Energy Will Not Support Economic Growth

Renewable Energy Will Not Support Economic Growth

The world needs to end its dependence on fossil fuels as quickly as possible. That’s the only sane response to climate change, and to the economic dilemma of declining oil, coal, and gas resource quality and increasing extraction costs. The nuclear industry is on life support in most countries, so the future appears to lie mostly with solar and wind power. But can we transition to these renewable energy sources and continue using energy the way we do today? And can we maintain our growth-based consumer economy?

The answer to both questions is, probably not. Let’s survey four important sectors of the energy economy and tally up the opportunities and challenges.
The electricity sector: Solar and wind produce electricity, and the fuel is free. Moreover, the cost of electricity from these sources is declining. These are encouraging trends. However, intermittency (the sun doesn’t always shine, the wind doesn’t always blow) still poses barriers to high levels of solar-wind electricity market share. Grid managers can easily integrate small variable inputs; but eventually storage, capacity redundancy, and major grid overhauls will be necessary to balance inputs with loads as higher proportions of electricity come from uncontrollable sources. All of this will be expensive—increasingly so as solar-wind market penetration levels exceed roughly 60 percent. Some of the problems associated with integrating variable renewables into the grid are being worked out over time. But even if all these problems are eventually resolved, only about one-fifth of all final energy is consumed in the form of electricity; how about other forms and ways in which we use energy—will they be easier or harder to transition?
