The lab aims to turn on the first-of-its-kind reactor by 2023. The program has maintained its aggressive timeline during the COVID-19 pandemic, using remote work to continue design and analysis efforts. [TCR video]
TCR will introduce new, advanced materials and use integrated sensors and controls, providing a highly optimized, efficient system that reduces cost, relying on scientific advances with potential to shape a new path in reactor design, manufacturing, licensing and operation.
As part of deploying a 3D-printed nuclear reactor, the program will also create a digital platform that will help in handing off the technology to industry for rapid adoption of additively manufactured nuclear energy technology.
Through the TCR program, ORNL is seeking a solution to a troubling trend. Although nuclear power plants provide nearly 20 percent of U.S. electricity, more than half of U.S. reactors will be retired within 20 years, based on current license expiration dates.
All nuclear engineering core courses are offered once a year. In addition to nuclear engineering courses, students are required to take the electrical engineering, engineering mechanics, and mechanical engineering courses listed below.
In the senior year, all nuclear engineering students enroll in two Nuclear Engineering Technical Electives (NUCE TE). NUCE TE courses are 400-level NUCE courses, except NUCE 401, that are not required in the nuclear engineering B.S. curriculum. Please refer to the University Bulletin for a list of 400-level NUCE classes. NUCE TE courses can also be taken to satisfy the GTE requirement.
ASME's Conference for Advanced Reactor Deployment (CARD) connects executive leaders and engineers in the small modular reactor (SMR) and micro reactor nuclear technology industries with utility, regulatory, and financial leaders to discover opportunities in the nuclear supply chain and advance clean energy solutions. The program is designed to not only showcase the latest reactor technology but also encourage meaningful dialogue in a comfortable setting. Attend CARD to:
Small modular reactors (SMRs) are advanced nuclear reactors that have a power capacity of up to 300 MW(e) per unit, which is about one-third of the generating capacity of traditional nuclear power reactors. SMRs, which can produce a large amount of low-carbon electricity, are:
In comparison to existing reactors, proposed SMR designs are generally simpler, and the safety concept for SMRs often relies more on passive systems and inherent safety characteristics of the reactor, such as low power and operating pressure. This means that in such cases no human intervention or external power or force is required to shut down systems, because passive systems rely on physical phenomena, such as natural circulation, convection, gravity and self-pressurization. These increased safety margins, in some cases, eliminate or significantly lower the potential for unsafe releases of radioactivity to the environment and the public in case of an accident.
That is one reason for the interest in small modular reactors. For plants now running, construction was sequential. Builders constructed the foundations, buildings, and other civil works first, then built a big reactor inside the building. If a reactor could be built in a factory, with a handful of parts, it could be fabricated at the same time as the buildings and other civil works so that construction would be parallel. Then the reactor could be trucked to the site and bolted together promptly. That only works with reactors that are substantially smaller than what is running today, so some new nuclear energy plant designs call for twins, quadruplets, or even a dozen reactors on a site.
Another prominent company in the advanced reactor field, X-Energy, has a reactor with an inherently flexible design, using a kind of fuel that is more tolerant of temperature swings. Its initial plan is for a cluster of four reactors that will make electricity, but its longer-term market is likely to include industries that need steam for process heat, and who want to get that energy from non-emitting sources. The electric sector is not the only one that has to be decarbonized.
In addition to developing a vibrant, cutting-edge research program, the successful candidate will have the opportunity to teach and develop undergraduate- and graduate-level courses in the areas of neutronics, transport, reactor design, reactor safety, and reactor licensing, and to mentor students at all levels. Candidates will have to demonstrate a commitment to excel in teaching and mentoring.
With IndustrialCraft2, the reactor system is fully recoded! Instead of lame Uranium refining, you now have to make a good setup for your reactor with all the reactor stuff you can find in the navigation. But one thing wasn't completely changed: nuclear meltdowns!
Once you have your reactor, you want to get some power out of it. The nuclear reactor acts like a chest. Place the right components in the reactor in the right locations, and voila -- nearly free energy! Place the wrong components or in the wrong locations, and BOOM!
If you apply a lever ON/OFF switch, this reactor will produce 5 EU/t. It will also generate 4 heat per second into the heat vent, and the heat vent will try to dissipate 6 units heat, only find 4, and dissipate that. Which brings us to a key concept in reactor design: heat.
Even a safe reactor design can be dangerous if misused, and honestly, what's the fun of a safe design when a dangerous one can be so much more efficient But no one wants to see their base reduced to slag. There are ways to protect yourself in the event of a meltdown.
All reactor designs fall into a set of pre-defined categories. This makes it easier to see, at a glance, how effective a design can be when either looking up designs on the IC forums or posting a design yourself.
The efficiency of a reactor is also appended to its classification. To calculate efficiency, take the number of uranium pulses a design makes per tick and divide it by the number of uranium cells it possesses. Efficiencies of five or greater are not possible without neutron reflectors and/or dual or quad cells, which were introduced in 1.106.
For information on nuclear reactor mechanics and components for old versions of IC2Experimental (pre-Minecraft 1.3) and IC2, see Old Reactor Mechanics and Components.Note that cooling has changed significantly, so if you're used to an old version of IC2, be sure to read about the new mechanics carefully!
Now you can spread heat through all reactor components and balance it amongst all storage units. But unless you intend to constantly replace the storage components, the heat will merely accumulate all over the time. To solve this, our engineers designed HeatVents (aka Vents, Heat Ventilation, Ventilators, Fans, Followers...).
But the NRC has not actually created the new regulatory process. Nor have they approved any applications for advanced nuclear reactors. And what gives people in the industry heartburn is that the NRC has, in fact, never approved a nuclear reactor from start to finish since its creation in 1975.
Meanwhile, air pollution is the cause of a bit over 100,000 premature deaths each year in the United States, so the cost of shifting at the margin from nuclear to fossil fuels is very high. And while natural gas is low-pollution compared to coal or oil, a single natural gas explosion in 1944 killed roughly 10 times as many people as all U.S. nuclear accidents combined. Even the high-end estimate of the worst nuclear accident ever is much smaller than the annual death toll due to fossil fuel plants operating as designed.
Thanks for this, Matt. As a trained and experienced nuclear reactor operator (Navy propulsion) I can tell anyone that reactors are safe, reliable, and can be built. The Navy gets around the NRC by using a different organization: Naval Reactors. NR is very stringent but they also understand that reactors must be built. So we've had new classes of submarines, aircraft carriers, approved in timely fashion and relied on for national security for decades. Not a single nuclear incident. They are refueled every 25 years. Compare to my other ship while serving, which ran on jet fuel and had to refuel every other day. Nuclear power is an amazing achievement of engineering and science, and I wish that more people were doing cost-benefits here instead of knee-jerking and feeling proud of themselves because they \"failed conservative\".
I spoke with the Oklo co-founders, and they seem confident they can provide the requested information and that the NRC will grant the license in the end. But they also say they are frustrated by a lack of communication over the course of this very long process. The 1.5 megawatt Aurora reactor in question is very small, but it\\u2019s not as if it\\u2019s being constructed in someone\\u2019s backyard. Oklo\\u2019s business plan is to build and sell lots of small reactors, but the reactor in question is being built in partnership with the Energy Department\\u2019s Idaho National Lab with the idea that INL will provide Oklo with the reprocessed nuclear waste that serves as Aurora\\u2019s fuel.
Stepping back from the particulars of the regulatory process, it is the policy of the United States government to promote a new generation of advanced nuclear reactors. That\\u2019s why Congress passed the Nuclear Energy Modernization and Innovation Act in 2019 directing the NRC to develop a pathway for licensing small reactors. It was the Trump administration\\u2019s policy to promote advanced nuclear reactors, it was the Obama administration\\u2019s policy to promote advanced nuclear reactors, and it is the Biden administration\\u2019s policy to promote advanced nuclear reactors. 59ce067264
