The Top 10 Nuclear Power Countries

0

All week we have looked at various different aspects of nuclear power generation.  Today lets look at some top 10 nuclear power countries based on different categories: Percentage of national power generated from nuclear reactors, Largest number of nuclear reactors, Largest number of nuclear reactors shut down, Largest number of new nuclear reactors and MW planned, and Most energy power capacity.

To find the information that we want, there are several places that we can start but the three that will be used in this article are theInternational Atomic Energy Agency (IAEA), the Nuclear Energy Institute (NEI), and the World Nuclear Association(WNA).  All three are international organizations that support the peaceful use of nuclear power.  The WNA has the most recent figures with statistics for 2010. Both the NEI and IAEA have figures from 2008 with the NEI having some statistics for 2009.

According to all three, the ten countries in 2008 and 2010 with the highest percentage of national power generated from nuclear reactors is:

CountryPercentage
1France76.2
2Lithuania72.9
3Slovakia56.4
4Belgium53.8
5Ukraine47.4
6Sweden42.0
7Slovenia41.7
8Armenia39.4
9Switzerland39.2
10Hungary37.2

 

The top ten countries by number of nuclear reactors:

8India172182
9Germany1728.81728.3
10Ukraine1547.41547.4

 

The top ten countries by nuclear reactor shut down in 2010:

CountryNumber of reactors shut downNumber of MW taken off line
1US289764
2UK263324
3Germany195879
4France113798
5Russian Fed.5786
6Japan51618
7Italy41423
8Ukraine43515
9Bulgaria41632
10Sweden31225

 

The top ten countries by new nuclear reactors and MW planned and under construction in 2010:

CountryNumber of new reactors plannedNumber of MW planned
1China3738,360
2India2321,500
3Japan1317,915
4US1113,800
5Russian Fed.78,000
6South Korea68,190
7UK46,600
8UAE45,600
9Canada44,400
10South Africa33,565

 

The top ten countries by number of MW generated in 2010:

CountryMW from nuclear power
1US101,119
2France63,236
3Japan47,104
4Russia21,743
5Germany20,339
6S. Korea17,716
7Ukraine13,168
8Canada12,652
9UK11,035
10Sweden9,399

 

As the above tables show, percentage of national power generated does not mean the most nuclear reactors or the greatest number of MW generated.  Just as the US has the greatest number of nuclear reactors currently  generating power, it also has the most nuclear reactors shutdown.  China and India are both planning to build considerably more nuclear reactors than any other country, but the power needs of both countries is growing much faster than those of most other countries.

Regardless of how anyone feels about nuclear energy, it provides the main source of power for several countries around the world.  When those reactors are shut down due to age or malfunction, it will be hard to replace the energy generated by those reactors with only one source of power.
