Saskatchewan Uranium Development

Hey folks,

In the last couple weeks, a public consultation forum on uranium development in Saskatchewan has been traveling the province, gathering input from citizens on the further development of the uranium value chain in the province. This discussion is looking at the Uranium Development Partnership's (UDP) report and recommendations to the province on what should be done. The trigger for this process is the strong growth our province has seen in recent years, and the forecasted future growth. With growth in the economy and population comes increased power demands. On June 15th, I attended the forum in Saskatoon.

SaskPower is a part of this process, because by 2020 between economic growth and retired assets they need to come up with an additional 1700 MegaWatts (MW) of generating capacity. A nuclear reactor can make up 1000 MW of this gap, which is why this discussion is happening right now.

I'll come out and state where I'm coming from. In the decade that I've been working in professional jobs, 6 years have been spent in the nuclear industry in Saskatoon. I believe that while the industry did not perform well in the 50s and 60s with regards to the environment, the necessary environmental and regulatory framework is in place to ensure these types of projects show the utmost care for the environment. The industry has numerous professionals that work with regulators on environment assessments and licensing.

That being said, I'm not completely sold on the idea of building of a reactor based PURELY on the economics. Nuclear reactors are big and expensive, and I'm not sure with all the associated upgrades required to our grid we can afford it. That being said, the forum was interesting, although the "anti-nuke" crowd was there in full force. A lot of what was said was informed dissent and gave me some pause for thought, and a lot was based on misguided assumptions or simply fear mongering. My favourite example was the idea that nuclear material is altering our DNA through soldier's semen. Not an exaggeration.

Here are a few discussion points I'd like to make about this:

1. Many people at the forum seemed to think this was a choice between nuclear and other cleaner power options such as wind, solar, and hydro. That is not the case. There is still 700 MW of capacity that SaskPower needs to come up with, and renewables will be part of that mix. Wind and solar are social no-brainers, which is why large public forums like this one are not required for renewables.

2. Many people also had the impression we are not looking at solar and wind as options, and that is not the case. The province currently has 170MW of wind turbines scattered around the Swift Current area. As a former resident of Swift Current, I can't think of a better place for wind power in our province. SaskPower is looking at expanding this capacity all the time.

3. Some folks in attendance are convinced that wind, hydro and solar power can replace our fossil fuel generation completely. Unfortunatly, with current technology this is not the case (unless we use nuclear as well). The technological issue with wind and solar right now is energy storage, and I'll outline why this is important. As I'm writing, the temperature today is forecasted to approach 30 degrees. When the hottest part fo the day hits, air conditioners in homes and offices will be working the hardest and consuming the most power. To manage this, power plant operators forecast this and will bring increased capacity online to cover the spike in demand. This is done by consuming more natural gas or coal to run additional turbines in a power plant. Right now, this demand management is not possible with wind or solar. If we have a windy day of 80km/hr but the additional power generated is not required it can not be saved for the calm hot day. Operators can not turn on the wind or the sun to meet increased demand. Can wind and solar be an integral part of our energy mix? Absolutely, but natural gas, coal, or nuclear must also be part of our mix for the purposes of demand management.

4. Nuclear is often touted as a clean energy source, and compared to fossil fuels it is. However, a good point is raised that the mining, transport and construction processes use a lot of fossil fuels (namely diesel). This is true, and is a valid argument. However, one must remember that solar panels do not magically appear, they have to be manufactured. Components in photovoltaic solar panels use precious metals (such as cobalt, cesium, and platinum) in their manufacture. These metals are mined, just like uranium, and most of it comes from areas such as South America and Africa. So, once the product is mined and refined, it has to be transported to the United States, Mexico and SouthEast Asia where it is a raw material in the manufacturing of solar panels. A lot of fossil fuels are consumed in this process as well. This is not saying that solar is not a viable option, but it is a comment that the manufacture of most products has an extraction and transportation component to it that uses fossil fuels.

Thats all for today,

Cheers.
