Nuclear power's deepening crisis : Comments

By Jim Green, published 16/10/2017

There are clear signs of a nuclear slow-down in China, the only country with a large nuclear new-build program.

Thanks Nick,

Jimbo has been predicting the failure of nuclear, and its "horrors" with little reference to the facts for a while.

Quoting renewables 'capacity' rather than 'production' is a common trick of climate alarmists. It makes renewable installations sound so much more impressive. But it is mileading.

My roof solar panels have a capacity of 4.5kwh but are currently producing 0.0kwh because it is night time, which makes up half the 24hr day. My panels are ideally facing north at the ideal angle, but at the sun's peak today it was producing just 1.5kwh because it was cloudy. This is just 30% of production capacity and cloudy days are very common in winter and somewhat common in spring and autumn. Over an entire year, taking out nightime and accounting for cloudy days and the inclining and declining angle of the sun, most solar panels are lucky to achieve an average of 20% - 30% of capacity - more with solar tracking.

The average production of wind farms is around 30% of nameplate capacity. Though a study of over 3,000 wind turbine installations showed that production falls as much as 50% due to wear and tear over half the turbines expected life.

We can also expect that solar and wind productivity will decrease overall as the best locations for siting major installations are quickly running out.

Coal and nuclear installations accounted for 30% of new capacity in China for first half of 2017. We know that they will produce at close to 100% of their capacity, if required.

Renewables might have made up 70% of installed capacity, but they may only be able to yield at best an average of 30% of their name plate capacity.

So to compare apples with apples using simple arithmetic, new production capacity installed in China in the first half of 2017 was more likely 59% Coal/Gas/Nuclear, vs 41% renewables.

Some of us knew about availability of sun and cloud and wind before the called 'renewable' BS was suggested. LOL
