There are smaller versions of existing light water reactors, like those in the U.S., France, Japan, and elsewhere. There are many new SMR companies in the U.S., Canada, U.K., Europe, China, and elsewhere, and the reactor designs themselves are numerous as well. Very few of the proposed SMRs have been demonstrated and none are commercially available. Most of these designs are just that: designs. In this case, Oklo refused to fill “information gaps” related to “safety systems and components.” And note that such rejection is an accomplishment: the NRC rarely outright rejects an application, instead working with licensees until they either get the application right or decide to walk away. Nuclear Regulatory Commission, the country’s nuclear safety regulator (full disclosure: I was Chairman of the NRC from 2012-2014). The Oklo story is intriguing, since its license application to build and operate its Aurora design reactor was outright rejected by the U.S. SUGGESTED READING The truth about nuclear deterrence By Herbert Lin Oklo’s news is a sample of the almost-constant barrage of excitement around the potential of small modular reactors (SMRs) to help mitigate climate change. Co-founder of AltC Acquisition and Chair of Oklo’s board, Sam Altman, hopes to raise US$500 million with this offering. News broke last week that Oklo, a company that has designed an advanced micro-nuclear power plant, will go public via a merger with AltC Acquisition Corporation. By exploring the challenges facing small modular reactor technology, I will demonstrate that this resurgence in nuclear energy speaks to the popular imagination, rather than materializing as actual technological innovation. In the past few years, investors, national governments, and the media have paid significant attention to small modular nuclear reactors as the solution to traditional nuclear energy’s cost and long build times and renewable's space and aesthetic drawbacks, but behind the hype there is very little concrete technology to justify it. With large nuclear power plants struggling to compete in a deregulated marketplace against renewables and natural gas, small modular reactors (SMRs) offer the promise to save the nuclear energy option. Small modular reactors have received billions in venture capital and unprecedented media attention, but are they a red herring, with philosophy, rather than science, driving our fixation? Professor Allison Macfarlane explores the current sombre state of the technology, where it is falling short, and what philosophy is driving the interest in this unpromising tech.įrom the inception of Oppenheimer's harnessing of the power of the atom, first as a device for war, and later, as a means of peaceful energy production, nuclear energy has possessed both promise and peril. Pupils follow a standard timetable covering all core and many optional subjects, and all have the chance to take part in enrichment programs in and out of school.Īt Riverhouse students help run the school farm, on the farm students look after pigs, chickens, rabbits, quails, and other small animals.Nuclear energy is both lauded as a baseload renewable power and decried as risky, expensive and outdated technology. Venture Academy aims to provide a welcoming, safe and stable learning environment where pupils can learn the skills of acceptable behaviour and make good academic progress. Pupils come from within Warwickshire along with a small number from neighbouring authorities. The school admits pupils aged 9 to 16 with autism and/or a social, emotional or mental health diagnosis. Venture Academy (formerly Arden Fields School) is a coeducational special school located in Henley-in-Arden, Warwickshire, England.
