It’s time for our second to final Physics episode. So, let’s talk Einstein and Nuclear Physics. What does E=MC2 actually mean? Why is it so useful to us as physicists and humans? In this episode of Crash Course Physics, Shini sits down to go over the basics of it all.

Energy too cheap to meter – that was the promise of nuclear power in the 1950s, at least according to Lewis Strauss chairman of the Atomic Energy Commission. That promise has not come to pass – but with some incredible new technologies, perhaps it still could. The question is – should it?

If we want to convert mass into energy, fission gives the most bang for our buck. Unfortunately that “bang” can be literal. Use of nuclear energy may risk the proliferation of nuclear weaponry, and there’s also the problem of nuclear waste, and the specter of horrible accidents. This last one was painted in terrifying detail in the recent dramatization of the Chernobyl disaster. Nuclear reactors sound scary because the disasters are pretty epic. However the reality is that far, far more people die from straight up air pollution due to coal-fired power plants than ever died in a nuclear reactor accident. In fact the radioactivity around coal-fired plants is also higher due to the trace but completely uncontained radioactive products of coal burning.

But the most compelling attraction is that nuclear power doesn’t directly produce carbon emissions. In fact nuclear power may be our most sure path to reducing carbon emissions and halting climate change. But can we do nuclear power safely enough? There are modern ideas – including the much-hyped thorium reactor – that suggest maybe we can. Before we can understand those we’ll need to review how nuclear reactors work.

For more information on Michael Shellenberger, please visit www.tedxberlin.de. Michael Shellenberger is co-founder and Senior Fellow at the Breakthrough Institute, where he was president from 2003 to 2015, and a co-author of the Ecomodernist Manifesto.
Over the last decade, Michael and his colleagues have constructed a new paradigm that views prosperity, cheap energy and nuclear power as the keys to environmental progress. A book he co-wrote (with Ted Nordhaus) in 2007, Break Through: From the Death of Environmentalism
to the Politics of Possibility, was called by Wired magazine “the best thing to happen to environmentalism since Rachel Carson’s Silent Spring,” while Time Magazine called him a “hero of the environment.” In the 1990s, he helped protect the last signi cant groves of old-growth redwoods still in private hands and bring about labor improvements to Nike factories in Asia. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx

Revisiting Small Modular Reactors – The Future of Nuclear Energy? Get Surfshark VPN at https://surfshark.deals/undecided and enter promo code UNDECIDED for 83% off and 3 extra months for free! Although nuclear energy is reliable and a sustainable energy source, the nuclear energy debate rages on. It’s not considered the go-to solution in the renewable energy transition. Solar, wind, and hydro are getting all the attention. Nuclear reactors are big, expensive, and take a long time to build, but what if we could make them smaller, portable, cheaper, and safer. Small modular reactors are getting a lot of interest with the first versions coming online in China and new locations popping up in Canada. As well as former SpaceX engineers that have made things even smaller … to a micro reactor scale. Could this be the future of nuclear energy?

Correction on NuScale: “A single NuScale Power Module (NPM) provides 77 megawatts electric (MWe), with a 12-module design resulting in a total gross output of 924 MWe.”

The meltdown at a nuclear power station in Fukushima, Japan, ten years ago stoked anxieties about nuclear energy. But nuclear is one of the safest, most reliable and sustainable forms of energy, and decarbonising will be much more difficult without it.

MIT 22.01 Introduction to Nuclear Engineering and Ionizing Radiation, Fall 2016
Instructor: Michael Short

Ka-Yen’s lecture on how nuclear reactors work is expanded upon, to spend more time on advanced fission and fusion reactors. Lots of topics related to reactor operation are conceptually introduced – moderation, absorption, leakage, fast vs. thermal spectrum, breeding fuel, neutron poisons, and temperature/density feedback. This sets the stage for student control of the MIT reactor to come shortly.

Anything with the word nuclear next to it usually comes with a fair bit of misunderstanding. Hopefully this video demystifies the process of how nuclear fuels are turned into electricity and how we can use them in combination with renewables in order to reduce greenhouse gas emissions and the effects on the climate that come with high levels of them.

Of course, there are many things that have been left out this video as nuclear energy, just as with any other source, has many different factors that need to be taken into account when making decisions. In order to fully understand the situation and make decisions, I highly recommend that you do some research of your own on the topic, rather than simply base your opinion on a four-minute YouTube video.

It should also be noted that this video has been made from the perspective of the United States in general. Every area on Earth has different natural resources and environments that determine what works best there.
