SMRs

Fancy having a nuclear reactor in your back garden? Some experts are now saying the answer to our energy problems may well be mini reactors built in factories and delivered to wherever they are needed. Dr Fiona Raymond is Director of the National Nuclear Laboratory which provides “independent advice” to Government is interviewed. They would cover about the size of a football pitch.

Floating Nuclear

Russian State Expert Examination Board (Glavgosexpertiza) has approved the operation of the floating nuclear power plant Akademik Lomonosov. The authority said on 9 December it had approved the project in Russia’s northernmost city of Pevek that is being funded by Rosenergoatom, the nuclear power plant operator subsidiary of Rosatom.

SMRs

The US nuclear regulator is satisfied that NuScale Power’s small modular reactor (SMR) design can operate safely without the need for safety-related electrical systems. The reactor uses passive safety features, such as relying on convection, not pumps, to circulate water in the primary circuit.

Areva

The Atmea joint venture between France’s Areva and Japan’s Mitsubishi Heavy Industries (MHI) is to be reorganised following the sale of Areva’s reactor business to EDF, MHI and Assystem. Atmea was created in 2007 to develop, market, license and sell the 1100 MWe Atmea-1 pressurised water reactor combining both companies’ technologies. “Under the new structure, there will be fifty-fifty ownership of Atmea between MHI and EDF, along with a special share owned by Framatome.”

Fusion

Fusion power plants could provide energy for homes in just 20 years. Fusion power could provide energy to our homes in just over 20 years, according to scientists who are halfway towards proving the technology’s commercial potential. Thirty-five nations are contributing to the International Thermonuclear Experimental Reactor (Iter) being built at Saint-Paul-les-Durance in southern France. In December the Iter team announced that the £16bn reactor, said to be the world’s most complex machine, is now 50 per cent complete.

Overcoming a series of setbacks, an international project to build what could be a revolutionary nuclear fusion reactor, which will produce renewable energy, has reached a major milestone. Half of the infrastructure required for the International Thermonuclear Experimental Reactor (ITER) project has now been completed — seven years after construction officially began in 2010. More than just becoming a major achievement in modern engineering, the ITER project could be a source of clean nuclear fusion energy by 2025. And it all starts on the 180-hectare site in Saint Paul-lez-Durance in southern France.

Nuclear Science

This was the year that analysis of data finally backed up a prediction, made in the mid 1970s, of a surprising emergent behaviour in the strong nuclear force. The strongest of the known fundamental forces of nature is something of an enigma. It holds together the nucleus of every atom – easily overcoming the electromagnetic repulsion between the positively-charged protons in there. The simplest atomic nucleus, that of hydrogen, is a single proton, but even that is held in one piece by the strong force, so tightly that it never falls apart – or at least, it lives billions of times longer than the current age of the observable universe. Truly, strong and stable.

Floating Reactors

The launch of the two reactors on board «Akademik Lomonosov» is now officially schedules for autumn 2018, Russian nuclear power station subsidiary Rosenergoatom announces. The mile-stone event takes place at Atomflot, the service-base for Russia’s fleet of nuclear-power icebreakers just a kilometer north of the nearest apartment blocks in Murmansk. The two 35 MW reactor units are of similar design as the reactors powering the icebreakers, the so-called KLT-40S. But instead of providing power to the propeller-shafts, the turbines on «Akademik Lomonosov» will produce electricity and heat. This week, one of the two turbines was tested at the plant in St. Petersburg where the floating nuclear power plant is built. By next spring, all initial testing will be completed and the barge-looking plant will be towed around Scandinavia to Russia’s Arctic port on the coast of the Barents Sea. When arriving in Murmansk, the uranium fuel rods will be loaded into the reactors.

SMRs

A number of Finnish cities have begun studies to evaluate the feasibility of using small modular reactors (SMRs) instead of fossil fuels to provide district heating, according to Energy for Humanity. A recent study looked at completely decarbonising electricity, transport and heating in Helsinki through the use of small, advanced reactors. Most of the district heating in Finland is produced by burning coal, natural gas, wood fuels and peat, said the non-profit organisation, which is funded by philanthropic donations and advocates for climate action and energy access. It noted that while many Finnish cities have progressive climate policies and goals, they have struggled to decarbonise heating and liquid fuels.

Fusion

Recently, some organizations involved in the International Thermonuclear Experimental Reactor (ITER) program have corrected false and misleading information published on their Web sites, after reading articles published by New Energy Times. This report summarizes the way that some ITER proponents have misled non-experts about the potential power output of the ITER experimental nuclear fusion reactor, once it becomes operational. The misrepresentation is not exclusive to ITER; it has been a systemic problem in the fusion community for decades. ITER is simply the largest and most recent fusion project. Specifically, the proponents conflated the power gain ratio of the plasma (technically known as the fusion Q) with the power gain ratio of the device (technically known as the engineering Q). They took the value for Q-fusion and convinced non-experts that it was the value for Q-engineering. They did this not only by switching the Q-values but also by hiding the actual input power required for the reactor. This report also identifies people and organizations who have published false statements about the ITER design and function based on the information they were given by the ITER organization.
