what would happen if a fusion reactor exploded

Global warming is a fact. It is extremely challenging to approach energy breakeven with deuterium-deuterium reactions because their total reactivity is 20 times smaller than that of deuterium-tritium, even at much higher temperatures. time as well.). It is possible that in some reactors, the design is so flawed (unsafe) that they could reach critical mass and explode. Fusion, as produced in a reactor on Earth, is inherently unstable and not self-maintaining. These phenomena put the integrity of the reaction vessel in peril. Another intractable operating expense is the 75-to-100 megawatts of parasitic electric power consumed continuously by on-site supporting facilities that must be purchased from the regional grid when the fusion source is not operating. International Thermonuclear Experimental Reactor (ITER) is a project on But the other drawbacks remain—and reactors requiring only deuterium fueling will have greatly enhanced nuclear weapons proliferation potential. Answer Save. Answer Save. Researchers didn't have the funds or ability to Even if such alloys do become available on a commercial scale, very few municipalities or counties are likely to accept landfills for low-level radioactive waste. Just as for fission reactors, International Atomic Energy Agency safeguards would be needed to prevent plutonium production or tritium diversion. Among the greatest threats to the future of humankind are nuclear weapons and global climate change. The whole point here is that fusion will never work, never. Relevance. If it succeeds where past fusion reactor plans have failed, the technology portends a … This circumstance indicates that implementing any substitute for water coolant such as helium or liquid metal will be impractical in magnetic confinement fusion systems. With drought conditions intensifying in sundry regions of the world, many countries could not physically sustain large fusion reactors. The most widely known approach to making fusion happen involves a doughnut shaped vacuum chamber called a Tokomak. This exercises the standoff distance of inertial fusion with heavy ion beams (or lasers, except that they have fallen short of ignition) to surrounding the clean and miniaturized fusion explosions with a thick lithium layer (~1 meter). They… Read more », The comment by Mike O’Connor is important, but I have to point out that he has skipped the point that the neutron problem will be reduced to a non problem by the lithium layer Jassby mentions. all motor vehicles….that is the perfect closed loop….the battery car world should just be a stepping stone. These constraints will cause prolonged downtimes even for minor repairs. Nuclear weapons proliferation. In reactors with deuterium-only fueling (which is much more difficult to ignite than a deuterium-tritium mix), the neutron reaction product has five times lower energy and the neutron streams are substantially less damaging to structures. The Chernobyl comparison is not appropriate. If the fusion power is 300 megawatts, the entire electric output of 120 MWe barely supplies on-site needs. Can a Fusion Reactor Explode? BBC News - Can a Fusion Reactor Explode? Great read. However, the real question is what would happen if a fusion reactor, real or imagined was damaged and lost containment of the fusion reaction inside of it. The To produce usable heat, the neutron streams carrying 80 percent of the energy from deuterium-tritium fusion must be decelerated and cooled by the reactor structure, its surrounding lithium-containing blanket, and the coolant. I could theoretically hammer It's called plasma, and they're going to use 45 foot high superconducting Answer Save. In return, we promise our coverage will be understandable, influential, vigilant, solution-oriented, and fair-minded. This gargantuan advantage in fusion reactivity allows human-made fusion assemblies to be workable with a billion times lower particle density and a trillion times poorer energy confinement than the levels that the sun enjoys. Because external tritium production is enormously expensive, it is likely instead that only fusion reactors fueled solely with deuterium can ever be practical from the viewpoint of fuel supply. In that case, your reactor is likely destroyed, and a fuel leak will contaminate local groundwater. But through the use of promising fusion technologies such as magnetic confinement and laser-based inertial confinement, humanity is moving much closer to getting around that problem and achieving that breakthrough moment when the amount of energy coming out of a fusion reactor will sustainably exceed the amount going in, producing net energy. How would that impact tritium or plutonium generation? It has not been possible to measure the cross-section of this reaction experimentally because of these long time scales. made a successful fusion reaction last more than two seconds, and even Tritium will be dispersed on the surfaces of the reaction vessel, particle injectors, pumping ducts, and other appendages. I believe that while we could meet our energy demands with things like solar, wind, geothermal and other classic sustainable energy sources, our growth beyond that will be a lot harder without a viable method of producing large amounts of energy. Worse, the several hundred megawatts or more of thermal power that must be generated solely to satisfy the two classes of parasitic electric power drain places additional demand on water resources for cooling that is not faced by any other type of thermoelectric power plant. To make up for the inevitable shortfalls in recovering unburned tritium for use as fuel in a fusion reactor, fission reactors must continue to be used to produce sufficient supplies of tritium—a situation which implies a perpetual dependence on fission reactors, with all their safety and nuclear proliferation problems. What it boils down to ultimately is economic viability and risk reward. Can we mitigate the risk of climate change by continuing to burn fossil fuels? This is how it looks to wrangle plasma. Replacing the burned-up tritium in a fusion reactor, however, addresses only a minor part of the all-important issue of replenishing the tritium fuel supply. This building is specially designed with steel re-inforced concrete up to four feet thick to protect the reactor and hold in the results of a reactor breach. The short Even if it could be made to work, the power would be too expensive to use. One component goes bad and it simply stops. But I'd have to get access to someone's The reactor is part of the GregTech mod. This thread is mainly aimed at the devs. Fusion reactors must accommodate two classes of parasitic power drain: First, a host of essential auxiliary systems external to the reactor must be maintained continuously even when the fusion plasma is dormant (that is, during planned or unplanned outages). But fusion reactors have other serious problems that also afflict today’s fission reactors, including neutron radiation damage and radioactive waste, potential tritium release, the burden on coolant resources, outsize operating costs, and increased risks of nuclear weapons proliferation. Hi, Yesterday I tried a bit with BigReactors and I think that it’s a very nice and cheep way to get RF. an explosion. This circumstance aggravates the problem of nuclear proliferation discussed later. What I find kind of sad is that everyone seems to be only looking at what we need right now. If reactors can be made to operate using only deuterium fuel, then the tritium replenishment issue vanishes and neutron radiation damage is alleviated. Did you ever wonder what happened if you detonated a nuclear bomb in the Marianas Trench? And any type of nuclear plant must allocate funding for end-of-life decommissioning as well as the periodic disposal of radioactive wastes. Fusion plants are "better" (less damaging to humans and the environment, In GregTech 2.06, the reactor outputs 32,768 EU/t in 1,000,000 EU packets. 1) The bottom line is that they are developing a new technology that has With no water to cool the reactor, it got even hotter – the "meltdown" you've heard of. I'm not making that up. If the mass of fuel in a core is about 200 tons (for RBMK reactor) and the yield/weight ratio for the earliest fission bombs is about .05 MT/ton, then we're getting close. The most well-known example of magnetic confinement fusion is the doughnut-shaped tokamak under construction at the ITER site; inertial confinement fusion is exemplified by the laser-induced microexplosions taking place at the US-based National Ignition Facility. Storing the energy is also a problem as batteries degrade over time and there also exists energy losses when energy is stored and reused again, as conversion of energy is not perfect. they're not sure if it will work. Molten lithium also presents a fire and explosion hazard, introducing a drawback common to liquid-metal cooled fission reactors. indeed just like the reaction that occurs in the sun to create light and Thus, to avoid such turn of events in 2016 MILAMOS(Manual on International Law Applicable to Military Uses of Outer Space) project was launched. Because only about 30 minutes of fuel is present in the reactor at any given time (compared to a year’s worth in nuclear reactors), the implications of a nuclear complete catastrophe are many magnitudes smaller than a nuclear catastrophe. until my house was built.
