Sendai Restart and an Early Christmas Gift

The anti-nuclear lobby is getting all bent out of shape by the restart of one of the two reactors in Sendai in Japan. The restart of one of the worlds most effective anti-greenhouse-gas and anti-pollution power generation methods really rubs their medieval superstitions right up the wrong way.

Not to be outdone by the Sendai reactor, I thought I would indulge in a bit of Luddite antagonism as well.

Of course the best way to antagonize a superstitious hysterical self feeding fear monger is by referencing some impeccably researched and peer reviewed science and then to couple that to a small amount of simple mathematics to show that nuclear actually saves lives.

So here goes....( all figures rounded to one decimal place)

Take one Pressurised Water Reactor. As it has just restarted, we'll use the Sendai Reactor - See Wikipedia Here

The Sendai reactor produces just short of 13TWh of electricity per year. As they have only started one of the two reactors on the site then that will be around 6.5 TWh.

Or to look forward to the festive season: 2.2TWh by Christmas.

Now as for out impeccably researched and peer reviewed let us take this table from a paper by Markyanda & Wilson (published in the Lancet, referenced by Jim Hansen among others) (Full Paper Here)

I suppose we should figure out what fossil fuel the Sendai nuclear reactor displaces .... From an earlier post here we have the break down of what has replaced nuclear during the shutdown in Japan. (Post is Here)

Basically it breaks down as follows. Nuclear in Japan during the shutdown was replaced by:

46% Coal
47% Gas
7%   Oil

So the single restarted Sendai reactor (6.5 TWh/yr) will displace approximately 3 TWh coal, 3 TWh gas and 0.5TWh oil in a year.

Or if we want to get into the festive spirit, the Sendai restart will displace approximately 1 TWh coal, 1 TWh gas and 0.2TWh from oil by Christmas.

Lets rephrase these figures into death and illness using the table above.

The deaths, disease and illness prevented in a year from the single unit restarted at Sendai ( i.e. half of a solitary nuclear power plant) will cut pollution by such an extent that it will:

Prevent the deaths of 90 people
Prevent serious illness (hospitalization) of 840 people
Prevent minor (time of work) illness of 45000 people (yes you read it right - 45 thousand)

Or to simply look to Christmas 2015. This single restart late in the year (August) will.

Prevent the death of 10 people
Prevent serious illness in 91 more
and prevent minor illness in no less than 15000 people

Now whether you are a Luddite or not, that is a hell of a Christmas present for 15100 folk in Japan this year.

Fracking in Lancashire

So it looks like Cuadrilla has stuck big in Lancashire. Loads of Natural gas. Some reports say enough to meet our energy needs for the next 50 years. (see here)

A great many of the Great Green disciples of Huhne are lining up to whinge and moan about extracting this gas.  But really they ought to do their basic research first and then think things through. (Oh, how I wish!)

Let us see how fracking for gas relates to their BIG idea. aka Wind Turbines. Wind turbines are, after all, truly BIG. Large in size but unfortunately minuscule in ability.

We know, (and they know) all about intermittency and unreliability etc. often expounded on in this blog, I won't go on about it any more here than just to say that even the most inflexible Luddite supporter of these things has to confess that they need considerable backup for when the wind doesn't blow.

Because Wind Turbine output is so unpredictable and massively variable over short periods of time, the forms of backup are limited. The backup is mainly limited to Open Cycle Gas Turbines, although some Closed Cycle Gas Turbines can be used at a pinch for less violent changes in output.

What do you power OCGT or even CCGT on?  Yes. That's right. Gas.

So if (God forbid) we carpet our country with these useless wind turbine monsters, where will the gas come from for the necessary spinning reserve?

Magic?

Or perhaps we could just get the whole population chewing on Mung beans for a fortnight and then plumb them into the nearest OCGT.

Those two suggestions are far more lucid and coherent than anything you will find coming out of the Green party or their comrades.

Of course, Fracking needs to be controlled and monitored. But the ridiculous, ill informed and politically biased charade of mortified concern that is being pumped out by the Greens  and others is simply absurd.

Now, what about my back yard?

Well, I live in Purbeck in Dorset. We currently have the largest on-shore oil field in the UK. It is quite likely that the Kimmeridge shale will also hold a considerable amount of gas.

Over many years, the oil field has performed impeccably. There is no reason to assume that any gas extraction would be any different.

If, you are going to build gas power plant you might as well use it efficiently. Then you can simply dispense with the wind turbines all together.

Actually, I would rather have nuclear plant, then you don't need gas. (at least for electrical generation). But either way we can dispense with the  fairy-land lunacy that is the wind industry.

So, if it is a choice between carpeting Purbeck with (as some suggest) 42 huge and useless wind turbines or have a few fracking gas extraction wells, give me the wells any day.
