NuScale - waste controversy
This time, a group of authors acted as critics, among whom stands out Allison M. Macfarlane, who headed the US Nuclear Regulatory Commission (NRC) for two and a half years.
In a journal called Proceedings of the National Academy of Sciences they published an article analyzing the amount of nuclear waste that will be generated in small modular reactors.
It is worth noting that in the United States, this concept includes not only radioactive waste, but also spent nuclear fuel, because in this country today it is not supposed to close the nuclear fuel cycle.
Small modular reactors (SMRs; i.e., nuclear reactors that produce <300 MWelec each) have garnered attention...

The main nonproliferation and safeguards challenges facing the small modular reactors
In recent years, the not yet very familiar acronym SMR (small modular reactor) has become a new development trend for nuclear power around the world.
The advantages of SMRs are quite obvious - there are fewer requirements to the power systems, in which they will work, lower cost, they can be built much faster, and the whole set of equipment will be manufactured in factory conditions.
Since a fundamental objective for the development of this technology is newcomer countries, the principal requirement for all designs of small modular reactors will be to minimize the potential for proliferation and terrorist activities through proliferation-resistant design approaches in combination with IAEA and other safeguards.
Despite the benefits, small modular reactors also have disadvantages. In this paper we want to highlight and explore how SMRs challenge the existing nonproliferation regime. And how various aspects of SMR designs such as: enrichment, fissile material...

And what has the rabbit thought?
Published project of the economic development of Russia till 2020 - Conception 2020 provides the construction of NPPs of the small and medium capacity for the power supplying to the isolated Russian energy zones and for the developing world economies. Appearance of small and medium - capacity reactors is called one of the indicators of reaching the aims of the state policy in the nuclear industry.
The fact of mentioning of small NPPs in program of the government is gratifying, but the absence of the specifics alerts. However, as a lot of people have noticed, friability and amorphism is characteristics to the whole item of the Conception, devoted to the nuclear energy.
What can be hiding above the restrained comments of the conception and what projects can be realized during the next decade?
According to the IAEA graduation small nuclear energy is the reactors with the maximum capacity of 300 MWe. In Russia by the small NPPs is frequently understood autonomous energy sources with the maximum capacity level of 50-100 MWe.
