Canada’s nuclear waste

After being removed from a reactor, nuclear fuel is both too radioactive and too physically hot to be reprocessed or placed in dry storage. As such, it is kept in cooling pools for a period of five to six years. Given the absence of long-term geologic storage facilities, all of Canada’s high level waste is currently in cooling pools or on-site dry cask storage. On a per-capita basis, Canada produces more high level nuclear waste than any other state – a total of 1,300 tonnes in 2001.

Canada currently has eleven nuclear waste storage facilities. Among these, one is in the process of decommissioning and six contain high level waste. Four sites have waste in dry storage casks: Darlington, Bruce, Pickering, Gentilly, and Point Lepreau. Other facilities include spent fuel pools. According to the Canadian Nuclear Safety Commission (CNSC), all Canadian wastes are currently in ‘storage’ defined as: “a short-term management technique that requires human intervention for maintenance and security and allows for recovery of the waste.”

In 2002, a major review of waste disposal options was undertaken by the Nuclear Waste Management Organization (NWMO). Their final report – released in November 2005 – endorsed a system of “Adaptive Phased Management” employing both interim shallow storage and deep geological storage, with the possibility of future recovery of materials. Such recovery would be motivated either by concerns about leakage potential or a desire to process the fuel into something useful. The NWMO is currently engaged in a process of site selection, intended to lead eventually to a National Nuclear Waste Repository.

The nuclear waste problem

From both an environmental and public support standpoint, the generation of nuclear waste is one of the largest drawbacks of nuclear fission as a power source. Just as the emission of greenhouse gasses threatens future generations with harmful ecological outcomes, the production of nuclear wastes at all stages in the fuel cycle presents risks to those alive in the present and to those who will be alive in the future, across a span of time not generally considered by human beings.

Wastes like Plutonium-239 remain highly dangerous for tens of millennia: a span roughly equivalent to the total historical record of human civilizations. Furthermore, while most states using nuclear power have declared an intention of creating geological repositories for wastes, no state has such a facility in operation. The decades-long story of the planned Yucca Mountain repository in the United States demonstrates some of the practical, political, and legal challenges to establishing such facilities in democratic societies.

Dry cask storage is not an acceptable long-term option, as suggested by its CNSC categorization as “a short-term management technique.” When dealing with wastes dangerous for millennia, it cannot be assumed that regular maintenance and inspection will continue. Storage systems must be ‘passively safe:’ able to contain the wastes they store for the full duration of their dangerous lives, without the need for active intervention from human beings. To date, no such facilities exist.

The implied right to pollute

In today’s news, there is some talk about the new report from the National Round Table on the Environment and the Economy. Much of it has surrounded the possibility of a carbon tax as a vehicle for assisting the with reduction of Canadian greenhouse gas emissions. One comment from the CBC struck me as especially wrong-headed. In relation to a carbon tax, a person being interviewed said that it “would specifically impact western oil producers who might have to carry the brunt of such attacks.”

The fallacy here is that western oil producers have the right to emit as many greenhouse gasses as they like, for free. If your neighbour was running a pulp mill in his back yard, allowing toxic chemicals to ooze throughout the neighbourhood, nobody would call it an ‘attack’ when he was made to stop. Arguments implying that industry or private individuals have the right to impose ecological harms upon others need to be challenged in terms of fairness and ethics. Otherwise, they obscure the true character of the situation and help to perpetuate the status quo.

Airborne and streaking eastward

I should now be in the air on my way back to Ottawa. Many thanks to all the people who helped to make my holiday in Vancouver so entertaining and personally meaningful. It has been a reminder of how important friends and family really are, and it has left me thinking with renewed energy about possible means of returning to British Columbia on a more permanent basis in the medium to long term.

For now, I need to get back on top of work projects and tardily finish my December book for the reading agreement with Emily.

Conditional support for our troops

Walking through the Rideau Centre yesterday, I came upon a cart selling t-shirts with various slogans on them. Beside the silly Che Guevara stuff was one shirt that caught my attention. In white letters on a red background it said “Support our Troops.” Under that were both a maple leaf and the flag of the United Nations.

It struck me as admirably post-nationalistic. We recognize the sacrifices made by members of the armed forces, but also that their conduct needs to be bounded by international law. While the sentiment is admirable, it sits uncomfortably with the reality of how ignorant most Canadians seem to be about what we are doing in Afghanistan. People really think we are mostly building bridges and distributing big bags of rice. The reality of the all-out war in which we are committed is very different.

That is not necessarily to say that we shouldn’t be fighting the Taliban along with our NATO allies; it is simply to highlight that Canadian governments manipulate the perception of Canada as a ‘peacekeeping nation’ to keep people from looking too closely at what our armed forces really do. The degree to which many people seem happy to continue to believe in the peacekeeping myth just because it makes them feel good is also problematic.

Milan’s Ottawa

Last winter, I made a map of the parts of Oxford in which I would be likely to find myself over the course of a week.

Here is my approximate Ottawa map:

It is basically defined by three corridors, leading from my home to work, the grocery store, and the Rideau Centre. During the summer, it would certainly have a few more tendrils. That said, it is a safe estimate that 50% of my time is spent within the tiny (unmarked) rectangles of my cubicle and bedroom.

Defending bike lanes over the web

MyBikeLane is an interesting concept in distributed social law enforcement. The idea is that people take photos of cars parked in bike lanes and then upload those to the site along with details on when and where the incident occurred. Since they can be sorted by license plate, the worst offenders can be easily identified. New York has by far the most active community, followed by Toronto.

Since I carry a digital camera at all times anyhow, I will keep my eyes peeled for possible contributions once I resume biking. For now, my small hybrid tires and the recollection of my nasty Halloween fall are keeping my bike in the basement.

I learned about the site from this interesting blog.

A few thoughts on climate justice

A couple of articles at Slate.com address the issue of ‘climate justice.’ This is, in essence, the question of how much mitigation different states are obliged to undertake, as well as what sort of other international transfers should take place in response to climate change. The issue is a tricky one for many reasons – most importantly because anthropogenic greenhouse gas emissions constitute a unique experiment that can only be conducted once. If we choose the wrong collection of policies, all future generations may face a profoundly different world from the one we inherited.

If we accept Stern’s estimate of a five gigatonne level for sustainable global emissions, that works out to about 760kg of carbon dioxide equivalent per person on Earth. Releasing just 36kg of methane would use up an entire year’s allotment, as would just 2.5kg of nitrous oxide. One cow produces about 150kg of methane per year. Right now, Canada’s per-capita emissions are about 24,300kg, when you take into account land use change. American emissions are about 22,900kg while those of India and China are about 1,800kg and 3,900 respectively. Because of deforestation, Belize emits a startling 93,900kg of CO2e per person.

The questions of fairness raised by the situation are profound:

Should states with shrinking populations be rewarded with higher per capita emissions allowances?
Should states with rising populations likewise be punished?
Should developing states be allowed to temporarily overshoot their fair present allotment, as developed states did in the past?
To what extent should rich states pay for emissions reductions in poor ones?
To what extent should rich states pay for climate change adaptation in the developing world?

It may well be that such questions are presently unanswerable, by virtue of the fact that answers that conform with basic notions of ethics clash fundamentally with the realities of economic and political power. We can only hope that those realities will shift before irreversible harmful change occurs. Remember, cutting from 24,600kg to 760kg per person just halts the increase in the atmospheric concentration of CO2. The level of change that will arise from any particular concentration remains uncertain.

Another vital consideration is how any system of international cooperation requires a relatively stable international system. While it is sometimes difficult to imagine countries like China and the United States voluntarily reducing emissions to the levels climatic stability requires on the basis of a negotiated international agreement, it is virtually impossible to imagine it in a world dominated by conflict or mass disruption. It is tragically plausible that the effects of climate change could destroy any chance of addressing it cooperatively, over the span of the next thirty to seventy years.

Rejecting Canada’s new copyright act

As a student, I was constantly being called upon to support various causes, through means ranging from making donations to attending rallies. Usually, such activities have a very indirect effect; sometimes, they cannot be reasonably expected to have any effect at all. Not so, recent protest activities around Canada’s new copyright act: a draconian piece of legislation that would have criminalized all sorts of things that people have legitimate rights to do, such as copying a CD they own onto an iPod they own.

Defending the fair use of intellectual property has become a rallying point for those who don’t want to see the best fruits of the information revolution destroyed by corporate greed or ham-fisted lawmaking in the vein of the much-derided American Digital Millennium Copyright Act. At their most controversial, such acts criminalize even talking about ways to circumvent copyright-enforcement technology, even when such technology is being mistakenly applied to non-copyrighted sources: such as those covered by the excellent Creative Commons initiative or those where fair use is permissive for consumers. Watching a DVD you own using a non-approved operating system (like Linux) could become a criminal offence.

For now, the protests seem to have been successful. Of course, the temptation for anyone trying to pass a controversial law is to hold off until attention dissipates, then pass it when relatively few people are watching. Hopefully, that will not prove the ultimate consequence of this welcome tactical victory for consumer rights.

Climate and the boreal forest

According to data submitted by Global Forest Watch Canada to the International Boreal Conservation Campaign (IBCC), Canada’s boreal forest contains 186 gigatonnes of carbon dioxide equivalent. That is equal to about 27 years worth of present global emissions. Permafrost – which is rich in methane – makes up about 25% of the world’s land area and about 50% of Canada.

Significant permafrost melting would release gasses that would accelerate the warming trend. Making boreal areas into parks and avoiding deforestation there isn’t a terribly effective mechanism for keeping the bulk of these greenhouse gasses in the soil. The trees themselves are increasingly threatened by pine beetles, as warm winters permit their continued spread. Maintaining the soils as a carbon sink essentially requires that they remain cold – an increasingly distant prospect as emissions continue to grow and other carbon sinks become saturated.

Boomtowns and bitumen

Since 1999, the population of Fort McMurray has nearly doubled. Primarily, this is on account of the oil sands: unconventional petroleum reserves whose exploitation is being driven by high prices and geopolitics. The demand for labour is dramatically increasing its price, both directly and indirectly. Apparently, inexperienced truck drivers can expect to make $100,000 per year. Shell has also just opened a 2,500 unit housing complex for its oil sands employees, part of their $12 billion in local infrastructure spending.

With oil around $90 a barrel and the atmosphere still being treated as a carbon dump, this is not terribly surprising. That said, such projects are certain to develop increasing momentum of their own. Once they bring enough jobs and money, they are hard for a provincial government to not support – especially if many of the environmental costs are being borne by people outside the province or by future generations. Internalizing environmental externalities through taxation or regulation becomes progressively more difficult as the incentive of certain parties to preserve the status quo increases. Such asymmetries are likely to give oil sands development a harmful legacy in terms of general policy development, in addition to its climate change effect and local environmental impacts.
