Do you have intuition on fp precision?
float16 - tennis court at 1 inch
float32 - small city at 1 mm
float64 - continent at 1 nm
float128 - supercluster at 1 nm
float256 - observable universe at Planck length
Now you have!
@StupidBill1@Atomicrod That’s awesome, but should depend strongly on core size. It’s not clear to me this scales up in a stable way when leakage feedbacks do less for you.
George Westinghouse would marvel at the incredible advances in nuclear technology that our namesake company has made over the last 75 years. About half of all the world’s nuclear power plants are based on Westinghouse nuclear technology.
Last week, “Bricks George” unveiled our advanced modular AP1000® PWR bricks set. You can see his bricks engineering buddy working below on a new AP1000 unit, just like the ones we are deploying across the world.
Now, we're giving away five Westinghouse bricks sets to people who reshare this post. We'll draw names on Monday from everyone who reposted!
You can build a mini-Westinghouse nuclear reactor at home!
@MattLoszak It’s not just that people have to want it; it’s that exceptionally driven people have to rise to answer the call! Wishing luck on the project.
@Object_Zero_@JamesRi34113613 Realistically reprocessing costs and fast reactor builds are so expensive that not even the most exuberant nuclear startups are proposing this at scale. You’d easily be talking LCOE > $200/MWh for this. Without a carbon penalty, the obvious choice is to burn gas.
Weak flow through this minion fireplace solved. I was tempted to run some CFD, but hand calcs suggested form losses transitioning to the chimney were dominating the pressure losses. So we straightened out the pipe from 45° to near vert and gave a manifold to reduce form losses.
Now she burns like a champ. There is a greater engineering lesson to be learned here: quick approximations get you most of the value and let you start iterating sooner rather than later.
@isaiah_p_taylor@nelvOfficial It’s correct for large LWRs. You’re running on HALEU and hitting something like 20 MWd/kgU with a graphite core that small no?
@Nuclearjunkie@Andercot@valaratomics Importantly: what burnup levels are claimed at discharge? That seems like a fundamental economic barrier given their goals.
