Inventor Suneel N Parekh is an energy pioneer. What keeps him going is a mixture of conviction and optimism. But even he knows he won’t get his project over the line without help. After decades he is finally bringing the proof of his methods to the attention of investors who can make or break his life’s work. Pioneers need backers. Just as The Beatles needed a deal before we could enjoy Sgt. Peppers, our energy pioneers need their break too - the … [Read more...]
Small Modular Reactors: interview with NuScale’s Jose Reyes
Dan Yurman has interviewed the co-founder and Chief Technology Officer of NuScale Power, Jose Reyes. NuScale designs and markets small modular reactors (SMRs). Its NuScale Power Module can generate 60 MW: small units, alone or combined, can suit a far wider range of energy demand than standard reactors that deliver hundreds of MWs at a minimum. The comprehensive interview covers international and U.S. developments, including plans to commence … [Read more...]
U.S. Military’s mobile mini-nuclear: fewer fuel supply convoys mean fewer casualties
U.S. Military figures show the resupply of liquid fuel and drinking water for troops in-theatre costs about 4 lives for every 100 convoys. It makes an army more vulnerable and limits movement. That’s why the U.S. Department of Defense is looking at very small modular nuclear reactors (vSMRs): sub-10MW nuclear units. They are already being designed, built and tested. If successful, no refuelling is required for years and the units can be … [Read more...]
South Korea’s nuclear ambitions face safety, quality issues
Dan Yurman summarises the regulatory, academic and press coverage of serious delays to South Korean nuclear reactors being built for the UAE. According to reports, these were caused by having to replace substandard components in reactors located in both South Korea and those planned for the UAE. There are problems with staff training too. South Korea recently completed the US NRC safety review process for its 1400 MW design. But the author asks … [Read more...]
More nuclear means more waste disposal: the options, science, engineering
Public concern about nuclear power goes beyond an accident at a live plant. What do we do with the nuclear waste? If nuclear is to grow to become a major replacement for oil and gas the question must be answered. James Conca reviews the different methods that have been seriously considered: shooting it into space, burying it in deep sea trenches or under ice sheets, transmutation, or simply digging it even deeper underground. … [Read more...]
SMR reactors: questions the “new nuclear” industry needs to answer
The new energy world is full of ambition about future developments, not least nuclear. At some point hard questions have to be asked and answered. Dan Yurman is asking questions about next generation Small Modular Reactors (SMRs). For example, why take on the unknown material and regulatory risk of SMRs over the known risks of proven LWRs? Which governments and/or investors will back the $500m needed to get an SMR into production? Where are the … [Read more...]
Next generation nuclear: 25MW, smaller, safer, can be sited anywhere
Dan Yurman looks at plans for Small and Micro Nuclear Reactors. A UK report on Micros that generate 30MW says it’s an opportunity for the country to own the IP and export units that are simple in design, factory constructed and capable of being sited in remote locations. Given the rough ride nuclear can get, the report warns that progress will depend on political, regulatory and financial support. Meanwhile, in the US, Westinghouse will have a … [Read more...]
Small nations have big plans for nuclear energy
Dan Yurman looks at how small nations are trying to increase their nuclear supply. Romania has the US and China both pitching for business. The Czech Republic is still vague about giving electricity price guarantees, something that caused the collapse of a $25bn nuclear tender in 2014. Ukraine looks at Small Modular Reactors. The author starts with the Baltics – net importers of electricity – and Estonia’s ambition to redress that balance using … [Read more...]
Can nuclear compete for a bigger role in the transition?
With plans to phase out coal-fired generators in most of Europe, nuclear is trying to compete with gas to become the most viable baseload power source to accompany renewables on the path to net-zero emissions. Both technologies have their advantages. Gas is competitively priced while nuclear generates power with almost no emissions. Right now, gas's cost advantage is evidently great enough to tip the balance. If nuclear advocates are to … [Read more...]
UK nuclear plans are in tatters. But current incentives help gas, not wind and solar, step into the gap
The scrapping of plans for a new nuclear power station in Cumbria and the suspension of work on another in Anglesey have put the brakes on the UK’s nuclear future. But the government appears more keen to fill the gap with gas rather than renewables. David Toke of Aderdeen University criticises the current incentives and regulations and makes the case for wind and solar. … [Read more...]
Nuclear power at the mercy of government subsidies while costs remain high
What affects the profitability of an investment in nuclear energy? What are the risks? Energy researcher and analyst Schalk Cloete presents his latest paper on the matter. He looks at the various effects on nuclear power investment, including the rise of other competing renewable energy sources, and the changing price of energy. *This article is brought to you via our new author platform. If you have an article you want to submit to us for … [Read more...]
Nuclear – critical choice for 2050
As the urgency of the climate crisis becomes more obvious, nuclear power is drawing another look. The power sector needs to develop to meet climate targets. Renewables (RES) have taken significant share of the energy mix in recent years but going further means securing far more investment and solving the complex challenge of integrating variable power. There is a need for alternatives to run alongside RES, keeping us on track. Matthew Wald from … [Read more...]
Britain has shifted 30% of its electricity away from fossil fuels in just nine years
Britain’s extraordinary energy transition is in part down to increased energy efficiency: put simply, less electricity was needed, whatever the source. But coal is still essential during spikes in demand. Given coal generation is due to be phased out by 2025, the country will need to find alternative power sources to cope during extreme weather events. And that overall decline in electricity demand is sure to be reversed as more vehicles and … [Read more...]
Will France spoil its nuclear future for short-term political gain?
President Emmanuel Macron of France is walking a tightrope. He wants to “Make Our Planet Great Again” and imposed a fuel-tax hike. But protests against the tax that spiralled into a debate about the cost of living have left him struggling with his energy policy, and what to do with the nation’s ageing nuclear reactor fleet. Dan Yurman separates the nuclear promises from the reality. … [Read more...]
Nuclear activity: UK, Russia, Japan, China and US all increasing capacity
Nuclear accounts for 10,5% (2017) of global power generation and is growing in many countries as demand for electricity increases. From 2012-2017, installed capacity rose to 392GW (an increase of 18GW). According to GlobalData, nuclear will continue to grow steadily over the next decade, reaching an estimated 536GW by 2030. Self-proclaimed "time traveller from the age of steam" Dan Yurman's NeutronBytes blog keeps tabs on all the latest … [Read more...]
