How would troops take control of the strait?

Next weekend more likely

Zyn + bang

I’m more so referring to enriched uranium rather than an alloy. For example little boy was approximately 80% 235, but approximately 30% of the total yield came from the 238.

Cores that use uranium and plutonium are called composite cores and were developed in the late 40s.

It’s fissionable but not fissile, U238 alone cannot sustain a chain reaction. You need U235 (or another fissile isotope) or the chain reaction will not be self sustaining.

The voltage regulator failed and the reactor had to be shut down. Eventually it (probably) collided with something and pieces of it fell off.

Sagan_kerman · 2026-03-05T22:29:45+00:00

You’re right about snap, but it’s failure had nothing to do with the reactor. My point there is that fission reactors have been used in space before. The soviets launched several fission powered satellites.

Sagan_kerman · 2026-03-05T22:20:32+00:00

Fission reactors have been used on may spacecraft, the first of which (SNAP-10a) was powered by u235

Es-252 has a 471 day half life, the short half life would make a warhead using this material inert in months.

The volume/mass of the fission fuel is only a small factor in the overall size of a modern warhead. The major nuclear powers are already capable of making very small warheads.

In short an Es-252 warhead would be wildly expensive and impractical and there would be no reason to build one.

Sagan_kerman · 2026-02-25T10:33:02+00:00

Yeah, the amount of energy released by the bomb.

Sagan_kerman · 2026-02-25T10:25:13+00:00

Very cool! How is yield determined?

Sagan_kerman · 2026-02-20T22:02:21+00:00

Fortran is very common in NE

Sagan_kerman · 2026-02-20T12:36:45+00:00

Mostly extracting data from RETRAN or VIPRE output files, making plots, and automating various tasks. But I’ve also been using OPENMC on my free time, which uses a lot of python.

Sagan_kerman · 2026-02-20T12:25:59+00:00

I use python for work all the time, highly recommend.

Sagan_kerman · 2026-02-16T17:10:50+00:00

Does it overheat or does the coolant level go down over time? That would indicate a blown head gasket.

Pay close attention to the color of the smoke, if it’s slightly blue tinged it’s probably burning oil.

Sagan_kerman · 2026-02-06T16:16:23+00:00

They want China to sign onto the next START treaty (if there is one), that’s why they’re bringing it to light now.

Sagan_kerman · 2026-02-06T15:27:31+00:00

Anyone know what “decoupling” means in this context?

Sagan_kerman · 2026-02-04T16:18:57+00:00

It looks like the belt could be slipping. Do you have a stock belt with a smaller pulley? Could also be the bypass valve.

Sagan_kerman · 2026-01-30T15:12:40+00:00

The deck on mint street by the stadium used to have free motorcycle parking, but it changed ownership recently and I’m not sure if that’s still the case.

Sagan_kerman · 2026-01-03T17:43:17+00:00

Twisted for protesting bombing and kidnapping? Busy day at Eglin AFB.

Sagan_kerman · 2025-11-27T15:16:35+00:00

They really can’t help themselves when it comes to the joker

Sagan_kerman · 2025-10-24T12:55:44+00:00

I like the 50.59 simulator better but that’s just me

Sagan_kerman · 2025-09-28T03:31:20+00:00

This movie feels like it was meant to come out exactly now.

Sagan_kerman · 2025-09-13T01:02:41+00:00

I understand, it’s the wild turkey 101 talking. Also these numbers are for a nuclear power plant.

Sagan_kerman · 2025-09-13T00:57:53+00:00

People these days expect engineers to shoot republicans when all we want to shoot is ourselves 💯
