Sam Altman is not reputable?

The Aurora is based on a reactor design that operated for 30 years. The tech is proven.

Another observation that I've had to support my hypothesis: NuScale is one of those entities doing something modestly different and has spent decades and hundreds of millions of dollars on just the regulatory component.

Here in Silicon Valley, there are a few nuclear startups working on various non-LWR concepts. One of them has done roughly the equivalent amount of work that NuScale has done but has only spent on the order of a few hundred thousand dollars, and with a team of less than 20.

So to me, it is clear that there are better and worse ways to go about things.

The world market is somewhere around $2Bn, even though current supply is not meeting demand. I think it can be much larger. If China and India were to use nuclear medicine at the same per capita basis as the US, those countries alone would be a market of $2Bn each, at a bare minimum.

I have proof of the desperate need of of these materials with two LOIs valued at up to $100M.

For the first phase of this project, which is mostly regulatory, I'm raising 1.5 on 12.

That is an interesting question that comes up a lot.

There really are no larger players who already operate reactors other than the power industry (power reactors generally cannot be used for radioisotope production) or government-run research laboratories. Realistically there is nothing preventing a government entity from joining the fun, but they will never be competitive. South Korea has spent several billion dollars designing a new reactor model and developing fuel for it (which I tested in ATR a few years ago, oh the irony!). It will be dedicated to doing the exact same thing I am. They've been at it since 2012 and they haven't broken ground on their facility yet. Last I checked the project caught a bad case of NIMBY.

The second part of the answer is that most of the processes are trade secret. If you dig deep enough, you can find a journal article or two from several decades ago, and even some newer ones where a different approach is studied. However, most of the existing players have an optimized process protected by trade secret. It takes a lot of domain expertise spread over several hard science fields to effectively get into the business.

No need to apologize for asking questions!

I'm using commercially available fuel that is available from fuel vendors. UO2 with zircaloy cladding.

As far as I'm aware, the NRC has no stated mandate for removing reactor-based methods. Or, if you have a source for that, I'd love to see it because that's a big deal. What you may be thinking of is the DOE/NNSA grants that are being given out for encouraging a domestic Mo-99 supply, which have strings attached which mandate it be for developing an "alternative" technology. I've found that the correlation is very strong between nuclear startups which have failed and which ones rely on government money.

I'd be curious why you think those projects have failed. I've had many discussions with other nuclear startups and friends at INL on this topic, and it's pretty nuanced.

Having been a DOE contractor, I have some... strong opinions about how nearly everyone in the industry operates or their approach to regulation. To refrain from ranting, I'll just say that it is my strong opinion that pretty much everyone does things "they way we've always have done them" and that everything is over-engineered and costs way more than it needs to. Most people I've spoken to seem to think it costs $100M to build hot cells. I know it doesn't cost that much to build a glorified box of concrete, even if that's what cost-plus entities have historically paid for them.

We could take this discussion offline as well, if you'd prefer. Then we can both be more specific and protect anonymity. Feel free to shoot me an email at [email protected] if you wish.

Another thought--one of my biggest challenges with speaking to investors is the fixation on the regulatory process because it can be onerous. Interestingly enough, because this project is much smaller and simpler than a power plant, it is actually a much more straightforward process than it is perceived to be.

The NRC has two guides for licensing non-power reactors: NUREG-1537 Parts 1 and 2. Part one lays out the format and information required in a license application, and part two is the review guide that the NRC uses to evaluate the application. So really, all of the questions AND answers are published. A prospective applicant just needs to say what they're doing, show how it meets safety criteria, and prove they're doing what they said they'd do when they build the thing.

It's obviously much more complex than that, but that's the gist of it.

Indeed, the first step is to get all of the regulatory approvals to 1) construct and 2) operate the facility.

Due to the simplicity of the reactor design and facility, and the low power it will operate at, it should take about 18 months for each of these approvals, and both can be (mostly) done in parallel. I anticipate production starting in 2024 or 2025. There are a variety of things that can speed this up or slow it down, but this is my best projection to date.

The Advanced Test Reactor is regulated by the Department of Energy, which is way more stodgy than the NRC can be, so I definitely appreciate the importance of navigating the regulatory environment carefully. It can take ten years if done horribly wrong.

The moderators personally emailed me to let me know that this question was asked but was snagged by a software filter, and has been "unkilled." I'll answer on your original post.

In my last paragraph I should clarify something that sounds confusing as I re-read it: "perceived demand" is dropping, but it is dropping as supply decreases. All of the literature out there suggests that the demand for radioisotopes in medicine is growing by 5-10% per year. I think it would be much higher with a more stable supply.

That's a huge boon. If you've already become familiar with nuclear codes by playing with OpenMC for fun, we may be talking sooner rather than later!

A radiochemist will help me determine the the size requirements of the hot cells for the final facility design. I understand the chemistry needed to separate out some of the most commonly used radioisotopes, but I don't have a sense of scale other than the processes being "bench top" scale.

Additionally, he or she (and with a few colleagues) will develop all of the processing procedures for the myriad isotopes that the facility will produce. A lot of what's publicly available for processing and purification has been optimized and is trade secret.

Another interesting problem is how to turn more of your waste into wealth? Currently, Mo-99 (the radioisotope with the largest market share) is primarily produced by extracting the Mo-99 from fission products. Mo-99 is produced in 7% of fissions. Well, if I process out the Mo-99, how many times and how many different processes on that waste can I perform to extract out other radioisotopes before I have to dispose of it?

Early on I'll need a radiochemist with a certain level of hands-on experience because their work will directly tie into the regulatory process, but as I raise more money and build my team, I'm certain that a computation chemist can help answer that last question which could be a huge innovation.

Thank you; that means a lot to me. I will definitely have to follow up sometime in the future.

By consolidating production facilities and positioning the facility as a factory, I can add some unique capabilities for moving things in and out of the reactor core.

As an example, most research reactors have a facility called a "rabbit tube" which is similar to the pneumatic tubes at a bank. You can basically shoot little capsules in and out of the core at will this way. But most of these reactors only have one of these tubes, or none, and every experiment they move in or out of the core is done by hand with 20 foot poles.

I want to automate the entire process by making every irradiation facility in the core accessible via a pneumatic tube system, and have a software system automatically eject material that had "cooked" long enough and send it straight to the chemical processing rooms via this shuttle system. This would drastically reduce human performance errors, reduce personnel requirements, reduce radiation exposure, reduce the capex required to move highly radioactive material around the facility, and allow me to move things in and out of the core without first needing to shut down the reactor.

In the short term, I'll most likely be sticking to the "cow" method, but as I learn more about that end of the supply chain, I'm sure I'll find more places to push for innovation.

I formed Atomic Alchemy in 2018 because I thought that one had to have the credibility of a formed company in order to ever receive investment.

With YC, you only need the idea, and you can form the company after you are accepted. And in my case, you can certainly bring an already-formed company to YC. In fact, a small number of companies accepted into YC are already profitable.
