There are a very few countries involved in the fabrication of complete nuclear power plants, However, more countries can produce important components of a nuclear power plant.

Regarding the use of nuclear energy for electricity generation, can be stated that exist in the world a total of 31 countries that use this type of energy source for this specific purpose.

Some important limitations  to use nuclear energy for electricity generation in several countries are, among others, the following:

1-Lack of the necessary technological development for the introduction of  a nuclear power program;

2-Lack of the necessary financial resources to support the use of this type of energy source for electricity generation.

3-Size of the national grid;

4-Lack of qualified manpower;

5- Strong opposition by the public to the use of this type of energy source for electricity generation:

6-Lack of the necessary infrastructure to support the use of this type of energy for electricity generation;

7-Lack of the necessary legal instrument to support the introduction of a nuclear power program.

8-Lack of political support to the use of nuclear energy for electricity generation.

Thanks for the valuable answer Dear Prof.Jorge Morales Pedraza 

But regarding the efficient workforce, Most of them have become immigrants and workers in these countries! 

Sustainable development is linked to protecting the environment and thus indisputably to the supply and use of energy. Though it is not problem free, nuclear power is recognized as having a clear advantage in contributing to the goals of sustainable development. For its entire energy chain from fuel production to waste disposal, it has limited emissions of greenhouse gases and other pollutants.

In the book: The National Politics of Nuclear Power: Economics, Security, and Governance by Benjamin K. Sovacool, Scott Victor Valentine, the authors assessed the nuclear energy evolution in two Nord-American countries, two European countries and four Asian countries and found a set of commonalities that play significant roles fostering nuclear reactor development. The six common drivers of nuclear reactors development are:

·        National security and secrecy;

·        Technocratic ideology;

·        Economic interventionism;

·        Centrally coordinated energy stakeholders network;

·        Subordination of opposition to political authority;

·        Social peripheralization.

In many countries, the lack of qualified personnel in the field of nuclear power has two important causes: First university students do not select nuclear careers because  it is difficult to find a good one within the University campus and second there are so many problems to find a proper job after graduated due to lack of sufficient infrastructure in the sector, particularly in the power sector  This is the case of the UK for example, in which the government wants to incrase the  use of nuclear energy for electricity generation and find many difficulties in hiring the necessary staff for operate the new nuclear power plants under construction or that will be constructed in the future.

Dear Salam,

The question raised here is highly relevant, this explains why there are so few answers !

Imagine a middle citizen in France, who consumes and works for this ; the nuclear energy he/she receives at home (light, heat, internet…)* is stored in his body and his mind ; he will empty this energy - spend calories for ex. - once at work. If he/she is the modal French, it is an employee ; so the residual claimant of the energy is naturally the employer : the energy stored (incorporated) in the body of the worker - a part of his real wage - is the same energy that directly feeds the firm (or others organizations). The (real) ‘consumer’ who is behind the consumer-buyer of the commodities (electricity included), it is the one who controls their production ; he uses some ‘use values’ that are stored in the ‘human capital’ he needs, the labour force he buys as a commodity, a stock of energy that produces commodities. The nuclear power is continuous and ‘cheap’ (for the employer) : it is just a mean to lower real wages and raise the interest on the advance of capital, via the profits. Nuclear power plants are highly capitalist : once you understand this, the answers to your question follow. The 'benefits' are money for capital, and no benefits for the humanity.

*The 'real' wage of the employee grows with this electric power ; this is not the point, but it explains a demand for this energy ; he sees a gain but not the loss, his power as a producer. 

I know that this is not the kind of answer expected here ; but there is no valuable answers to this kind of questions if you do not see commodities (energy included) as contracts for value. 

What a great answer and summary story 

Thanks, Joffrin Jean-Pierre
