Walking Toward Nuclear on Tip-Toe

cgs1 Energy Northwest is giving nuclear energy a look-see.

In a May 27 letter obtained by The Associated Press, the [Energy Northwest] consortium asked each of its 25 member public utilities and municipalities to pitch in $25,000 for further research into building one or more small reactors. Those who pay would have first rights to any power produced if a plant is built.

Well, that’s pretty small-d democratic. And Energy Northwest, which had a rough ride with nuclear energy in the 80s – the article goes into all that - is indeed proceeding this time most carefully:

Energy Northwest has spent the past year researching its nuclear options, including a 1,600-megawatt plant that would power more than 1 million homes, before deciding to gauge interest in a small project where 40-megawatt reactors can be added as needed.

Hmm, perhaps too carefully. Although the article doesn’t say it, it looks as though the idea may be to use the smaller plants to backstop their renewable portfolio (the article says wind, solar and biomass, but we think solar is really unlikely in raintown. These are hydro people, with the dams to prove it.)

Read the whole article – there’s a lot of detail in it – but we would note as a final point that the nuclear plant that did come out of the 80s debacle – The Columbia Generating Station – has hummed along quite nicely for the last 25 years. We can’t blame Energy Northwest for walking on tip-toe, because at least they’re walking in the right direction.

The Columbia Generating Station. Not terrible as industrial structures go.

Energy Northwest is not in Seattle! It is located in Eastern Washington near the Hanford Site. With 6-7 inches of rain per year and 300+ sunny days - I believe solar is also on their radar.

But this is certainy an interesting development - it is one of the few areas where the community would support new nuclear readily - though the state interests on the other side of the mountains may oppose.

This is very clearly an effort to look at deploying NuScale reactors.


Good for Energy Northwest.

I have not yet read the linked article, but have an immediate guess that the folks at Energy Northwest have been talking to their neighbors from NuScale, which is located in Corvallis, OR, the same town as Oregon State University.

The description of a 40 MWe plant module where additional modules can be added as desired fits right in with NuScale's concept of modular light water reactors using natural circulation coolant flow.

Now I need to go read the linked article to confirm my guess.

People may find the slides from a seminar given by Dr Reyes of Nuscale at MIT of interest.

Reyes presentation is odd. It seems to equate financial risk with severe accident risk, which is not the case. The likelihood of any severe accident is so fantastically low that it means almost nothing from a financial standpoint. In other words, nuclear power is plenty safe already. Reducing core damage frequency from 1E-7 to 1E-9 per year does not accomplish much to get a plant built.

The main financial risks are regulatory and political. Reyes never addresses that. Why would it be easier to build many 40 MW plants than it would be to build one 1000 MW plants? In many respects, the political and regulatory risks are independent of plant size. Nuclear power opponents and their lawyers don't care if the plant is 40 MW or 1000 MW; if it has fission products, it must be delayed and regulated out of existence, in their eyes.

Yeah, I get it: it is easier to build small ones and stack them up. But in the perserve economics and politics of nuclear power, that may or may not hold true. I don't see anything in Reyes presentation to address that, even though there's nothing I like better than doing PRA.

Why Ex-Im Bank Board Nominations Will Turn the Page on a Dysfunctional Chapter in Washington

In our present era of political discord, could Washington agree to support an agency that creates thousands of American jobs by enabling U.S. companies of all sizes to compete in foreign markets? What if that agency generated nearly billions of dollars more in revenue than the cost of its operations and returned that money – $7 billion over the past two decades – to U.S. taxpayers? In fact, that agency, the Export-Import Bank of the United States (Ex-Im Bank), was reauthorized by a large majority of Congress in 2015. To be sure, the matter was not without controversy. A bipartisan House coalition resorted to a rarely-used parliamentary maneuver in order to force a vote. But when Congress voted, Ex-Im Bank won a supermajority in the House and a large majority in the Senate. For almost two years, however, Ex-Im Bank has been unable to function fully because a single Senate committee chairman prevented the confirmation of nominees to its Board of Directors.

An Ohio School Board Is Working to Save Nuclear Plants

Ohio faces a decision soon about its two nuclear reactors, Davis-Besse and Perry, and on Wednesday, neighbors of one of those plants issued a cry for help. The reactors’ problem is that the price of electricity they sell on the high-voltage grid is depressed, mostly because of a surplus of natural gas. And the reactors do not get any revenue for the other benefits they provide. Some of those benefits are regional – emissions-free electricity, reliability with months of fuel on-site, and diversity in case of problems or price spikes with gas or coal, state and federal payroll taxes, and national economic stimulus as the plants buy fuel, supplies and services. Some of the benefits are highly localized, including employment and property taxes. One locality is already feeling the pinch: Oak Harbor on Lake Erie, home to Davis-Besse. The town has a middle school in a building that is 106 years old, and an elementary school from the 1950s, and on May 2 was scheduled to have a referendu

Why #NEA17 Is at the Intersection of Nuclear’s Present and Future

Nuclear power is working for America. On May 22, hundreds of engineers, scientists, plant operators, entrepreneurs and students will gather in Scottsdale, at the annual Nuclear Energy Assembly , to talk about the multiple benefits that our technology provides, and the challenges and opportunities ahead. In preparation, NEI's Matt Wald sat down recently with Lenka Kollar , the director of business strategy at NuScale Power , the company that submitted the first application for design certification of a small modular reactor . Lenka will be a panelist on the first day of the conference. NuScale is one of several companies working on small modular reactors, reactors that can be built in a factory and then shipped by barge, rail or truck to sites around the country or the world. It’s not quite plug-and-play, but it’s closer to it than anything the nuclear industry has done so far. NuScale is further down the path to deployment than others; the Nuclear Regulatory Commission rece
