Molten salt reactors MSRs use molten fluoride salts as primary coolant, at low pressure. This itself is not a radical departure when the fuel is solid and fixed. But extending the concept to dissolving the fissile and fertile fuel in the salt certainly represents a leap in lateral thinking relative to nearly every reactor operated so far.

Introduction to the Physics of Molten Salt Reactors

The latter would provide abundant, reliable and safe energy with no CO2 production, no air pollution, and minimal waste production. The ThEC13 proceedings are a source of reference on the use of thorium for energy generation. They also describe how thorium can be used in critical reactors and in subcritical accelerator-driven systems ADS , answering the important questions:. Skip to main content Skip to table of contents.

Thorium Energy for the World

Nuclear energy can play an important role in this context since it does not emit CO2 for power generation. However, there are still some concerns and difficulties in the current nuclear power such as nuclear proliferation, radioactive waste, safety, economy, usability etc. Therefore, there is a need for a novel nuclear industry for a global scale usage. Strong incentives for the molten salt reactor design are its good fuel utilization, good economics, amazing fuel flexibility and promised large benefits.

Thorium-based nuclear power generation is fueled primarily by the nuclear fission of the isotope uranium produced from the fertile element thorium. According to proponents, a thorium fuel cycle offers several potential advantages over a uranium fuel cycle —including much greater abundance of thorium found on Earth, superior physical and nuclear fuel properties, and reduced nuclear waste production. However, development of thorium power has significant start-up costs. Between and , the number of operational thorium reactors in the world has risen from zero, [1] to a handful of research reactors, [2] to commercial plans for producing full-scale thorium-based reactors for use as power plants on a national scale. A nuclear reactor consumes certain specific fissile isotopes to produce energy.

Molten Salt Reactors and Thorium Energy

Molten Salt Reactors is a comprehensive reference on the status of molten salt reactor MSR research and thorium fuel utilization. There is growing awareness that nuclear energy is needed to complement intermittent energy sources and to avoid pollution from fossil fuels. Light water reactors are complex, expensive, and vulnerable to core melt, steam explosions, and hydrogen explosions, so better technology is needed.

The liquid fluoride thorium reactor LFTR ; often pronounced lifter is a type of molten salt reactor. LFTRs use the thorium fuel cycle with a fluoride -based, molten, liquid salt for fuel. In a typical design, the liquid is pumped between a critical core and an external heat exchanger where the heat is transferred to a nonradioactive secondary salt.

Amongst all TMSR configurations, many studies have highlighted the configurations with no moderator in the core as simple and very promising. Thus, the current fuel cycle can be closed thanks to TMSRs started with transuranic elements on a Thorium base, i. We analyze the characteristics of these reactor configurations, in terms of fissile matter inventory, salt reprocessing, waste production and burning, and finally deployment capabilities. We thus confirm, beyond the classical advantages of molten salt reactors, the satisfactory behaviour of the TMSR and the excellent level of deterministic safety which can be achieved in such reactors. We then illustrate how the reactor can be driven with no control rod, either by controlling the extracted power or by monitoring the operating temperature.

Он едва дышал.

 - Кроме того, ТРАНСТЕКСТ уже больше двадцати часов не может справиться с каким-то файлом. Фонтейн наморщил лоб. - Это по вашим данным. Мидж хотела возразить, но прикусила язык.

Бринкерхофф читал, не веря своим глазам. - Какого чер… В распечатке был список последних тридцати шести файлов, введенных в ТРАНСТЕКСТ. За названием каждого файла следовали четыре цифры - код команды добро, данной программой Сквозь строй.

 Вы же только что прибыли. - Да, но человек, оплативший авиабилет, ждет. Я должен доставить эти вещи. На лице лейтенанта появилось оскорбленное выражение, какое бывает только у испанцев.
