Sodium is a rather nasty medium to use as coolant. It corrodes, and spontaneously catches fire on contact with air. Attempts have been made in the past, ending in expensive failures.

Yea, although given the reactor lifespan is listed as 6+ years, I wonder how much corrosion will occur. Clearly, preventing any leakage is key to avoiding unpleasant results.

For a moment, I read that as "supercriticality" and was more than a bit concerned. :-D

But seriously, that's great — both that it successfully reached that point and that it did so on the first try.

Yea, all it means it is producing more neutrons than is lost, so power increases as Moree fission reactions occur over time; a controlled process in nuclear reactors.

Comment Interesting design (Score 3, Informative) 106

From Antares' website, this appears to be a non-refuelable low power (100KWe -1MWe for 6+ years) reactor. The fuel design is not a new concept, pebble bead reactor designs have been for a while, and China appears to be working on one as well. The fuel design does have some advantages, such as online refueling, the ability to withstand the heat generated by the fission reaction without cooling, and in some designs the ability to disperse the fuel to shutdown the reactor. One challenge for earlier designs was the use of helium as a heat transfer medium which was hard to top from leaking past pump seals, etc. This design uses sodium/N2 loops, avoiding issues with helium. From their website, it appears they do not plan to scale it for utility use but focus on markets for small portable power that are not as cost sensitive, such as portable power for military use.

On the other hand, I don't necessarily want kids under a certain age to be viewing hard-core porn and kink websites. Still, how many of us straight guys didn't "borrow" a father's Playboy magazine to look at images of the female body in junior high and later before online porn exited?

I did for the articles.

So who is liable if an underage user circumvents the check? Do platforms make checks so intrusive to try to make it hard to circumvent at the cost of privacy? Should developers location block places with such laws to avoid violating the law because a user is underage but circumvented the check?

The authorized repair certification has some huge catches. You have to sign away your ability to use any third party parts whatsoever. And there are a lot of cases where that ability is more important. There are other restrictions that I can't remember for the moment outside of the cost.

No doubt, but you need not be one to buy the tools; but like I said I doubt most of the small fixit shops can afford the suite of tools they may need to repair iPhones or iPads. They may be able to if th emajority of teh tools are not model specific, I guess sit would depend on teh volume of repairs and how much easier it makes doing them.

With Apple, they will rent tools to end users and only if they self-certify that they aren't hiring any professional help in the process. Independent shops can't even buy the tools.

From what I can tell, Apple will currently sell their expensive tools to anyone, as well as rent them. Getting th tools needed to compete with Apple using genuine parts and tools would be a sizable investment and thus most shops are unlikely to be able to afford such an investment. I suspect shops that can are generally already Apple Authorized Resellers, so in the ned Right to Repair doesn't mean I Can Cheaply and Easily Fix My Device.

apple laptops will they do it or just pay the fine?

Given the ambiguity in the rules, it’s possible many Apple laptops already comply in that an end use can open the device and swap the battery, although it is not easy. The commercially available tools could be interpreted as long as the manufacturer offers for sale to anyone tools need to do the repair, they are commercially available and meet the letter of the law. I suspect, for most end users, the cost and difficulty will mean they forgo the DIY repair. A 3rd party shop might be able to afford investing in tools since the cost would be amortized over multiple uses.
