Praying for meltdown: The media and the nukes

John Smith 19 Gold badge
Flame

Always keep in mind the *first* objective of the media.

To stay in *business*.

You feeling you've been "informed" is a side effect.

And when it comes to staying in business and (in the words of mega-media-mogul-not-based-on-Rupert-Murdoch Elliot Carver) "Nothing sells like *bad* news"

The flood waters have subsided, the aftershocks have gone so no real chance of anyone *not* in Japan being affected. But a radioactive cloud *potentially* cover the *whole* globe...

That'll keep the viewers watching. That'll keep them tuned in for the *slightest* change in wind direction or radiation level. No one's actually *died* of radiation exposure (unlike the current death toll of about 20 000 due to drowning and being hit by bits of assorted buildings, but they're Japanese) but it could *always* get worse.

I note that the Channel 4 News in the UK has tried to be quite balanced by using people from the Dalton Institute of Manchester University (nuclear engineering) for opinions and when they stated a sensor in Edinburgh had measured 300 micro Bequrels of Iodine they put that in context by pointing out that Radon gas in houses exposes people to 20 000 000 micro Beqs (IE 20 Bequrels) which I think would give most people the idea this ain't much.

So the gate is isolated by an air gap rather than a silicon oxide layer.

We're looking at a notice period in *minutes*. If people don't have their plans ready to go (isolating sections of the electricity back bone, shutting down large furnaces to preserve the ability to make the steel for replacement transformers etc) this will be a total waste of time.

However I welcome international cooperation in this area so *cautious* thumbs up.

NHS to share foreigners' data with border agency

John Smith 19 Gold badge

One up vote, one down vote

That sort of sums up my view on this.

But the phrases "data sharing" and "Borders Agency" definitely red flag this as more creeping database state than improving use of scarce resources to me.

I think my view it's more BB stands.

International health -> international charging. A good idea in *theory*

However note if someone gives a false name how would they *know*??

I'm guessing this is for people who are getting *substantial* operations done inside the NHS.

But how is this *possible* when parts of the NHS are sending people to *France* due either to waiting times or expense.

How can a foreign patient roll up and get *this* level of service?

AFAIK the NHS still only has *informal* charge back arrangements with UK private health companies. If they f**k up they dump the case at the nearest NHS hospital but only 3 of them will *pay* the NHS to fix what they can't (although no doubt this is spelled out in the contract their customers signed). BUPA remains the the odd one out.

I'd like to see how many cases *they* dumped on the NHS last year, and weather they were foreign nationals. Heads they take the punters cash, tails they f**k up and still take the punters cash.

Overall it sounds a *whole* lot more BB than big society.

And that's *provided* they don't hand over the medial records because "How will we know if they have a medical condition if we can't see *all* their medial records just-in-case".

"The silence is deafening."

And so speculation (which is *all* pretty much all the comments are) fills the space instead.

This *both* a technical *and* marketing fail.

Technical because they appear to have assumed that this information would *never* get out. If you're going to behave in that way you'd better be *very* paranoid about where you keep it, who has access to it (does you CFO *really* have that MBA from Harvard?), what it's connected to (nothing preferably) and what information can be downloaded from it and to what output media. Not to mention having an *equally* secure backup system elsewhere in case of earthquake/flood/terrorist assult/whatever.

Given that these are the *core* components of what makes RSA valuable to *customers* even the *impression* that they have fallen into the wrong hands does severe damage to the reputation of the brand.

It's a Marketing fail because when the s**t happened (so much for the assumption) they appear (and that's *all* we can say about their response) to have *no* plan in place to handle this. Which suggests

a) They are making it as they go along in full headless chicken mode. Might be serious. Might not be *less* serious but they can't *quite* find the right words, or get approval to say them.

b) It's *really* bad and they they *can* fix it but their customers are going to take a *lot* of pain.

c) It's *really* bad and they can't fix it as who needs a backup up plan for something which will *never* happen? IOW They be f**ked (and so are their customers).

Anyone remember when Evian got contaminated with Phenol some years ago? Company came clean (no pun intended) within 24 hours. Explained what had happened and what they were doing about it and what customers could do about it.

Result. People continue (rightly or wrongly) to trust Evian as their preferred water supplier.

For a company with turnover in the 100s of $m (billion+?) this is a *very* poor response.

*very* impressive

Scaled up to EV sized batteries this would be a step change and with re-charging points as common as filling stations (in principle *more* common given its basically a socket + metering and billing hardware) and people *could* become quite comfortable with EV's.

Ironically the question might be now can it be built to discharge *slowly* enough not to fry the motors.

Obviously this is a *long* way from production and is certainly not the first battery tech that looked incredible in the lab but has not set the world on fire (unlike some of the successful ones, which on occasion have).

Thumbs up and I will wish them *every* success but this is just the start of the end of the beginning. IE about v0.1.

But if they make it to 1.0 I'll be cheering.

Let me see if I can precis this.

Workers who fought the Windscale fire have a *slightly* increased death rate relative to similar groups in the south of England.

But

Northeners are less fit than southerners and tend to die earlier.

There is no *significant* increase in the death rates between northeners working in Windscale and northeners working in any other bit of the north. In fact their was an apparently slight lowering (but this could just be noise).

QED Putting out a burning nuclear reactor does *not* shorten average life expectancy in a statistically significant way.

Rocket engineering *is* his day job.

Reaction engines have worked on the problems of making air breathing to orbit for the last 30 years. Rocket engineering is their day job too. Their download page is.

http://www.reactionengines.co.uk/pdf_documents.html

The pdf listed as "A Comparison of Propulsion Concepts for SSTO Reuseable Launchers"

explains the alternatives in non mathematical language. "The SKYLON Spaceplane - Progress to Realisation" describes their progress as of 2008. They are currently commencing their "D1" design update which should reflect lessons learned and issues closed since their design freeze in the early 90's.

Note that when Skylon was first designed (c1989) a *lot* of it's tech (or the equipment to build it) had simply *never* been built. Since then they worked with various partners to design (the fairly easy part), *build* and *test* key elements of the hardware. A useful lesson *any* developers looking to get into the space business with a limited budget should keep in mind.

A note on what kinetic energy can do.

There is a picture in the book "Birth of the missile" which shows a V2 test site. The guidance system during development was so unreliable the test team felt the safest place to be was the *target*.

That day the V2 was spot on.

IIRC correctly the V2 (*without* warhead) made a 30m crater.

At these speeds just *hitting* something will do some pretty serious damage to most things. The only sort of "warhead" you needs is something sharp, strong and *highly* temperature resistant to drive into the target.

Something like the Tungsten or depleted Uranium sabots in artillery shells for example.

It remains a *very* complicated way to do something which *can* be done in a *lot* simpler way.

Like a fashion model with a PhD in Comp.Sci. Interesting certainly but not actually *essential* to the job.

John Smith 19 Gold badge

Potentially *slightly* more useful than a Hydrogen fuelled scramjet.

But only just.

While making it run on JP7 makes it a *lot* more operable than either liquid or compressed Hydrogen. the ethylene is not really an issue. The SR71 needed a start tank of a very fierce organo-metal to fire up. It was only a few litres in capacity but good IIRC for 10s of starts. Ethylene is *benign* by comparison your still left with 2 problems.

Fixed internal geometry ramjets have *limited* speed ranges. If its designed for M2 it won't stay in ram mode much below and won't take much above. Widening that speed range *without* geometry change is something which AFAIK has *never* been attempted. The temperatures of the internal flow paths are Earth reentry level *continuously*, as are substantial parts of the outer skin.

So the fuel is really the *only* place to dump the heat if you want to run it continuously.

Problem 2 is you still need to get it *up* to ignition speed in the first place, preferably a *long* way from the ground.

And when you have made it *work* you've basically saved yourself the cost of a lox tank.

LOX is roughly 4600x the oxygen density at *ground* level (and at least 4 times better at its likely *minimum* operating altitude).

Its also the *cheapest* oxidizer (High concentration Hydrogen Peroxide is fairly rare and Nitrogen Tetroxide *very* hazardous), literally cents per lb.

This is really a weapons technology. It's *useless* for commercial functions until the problem of getting it up to ignition speed. No problem for missiles. Not much use for commercial traffic.

I'll take a wild stab at the thinking here.

1) It's a control system. *Assume* Information about it is difficult to get hold of as it's proprietary and frankly *no* one cares about them.

2) There is no need to connect it to the Internet (IRL the likelihood is that the PC used to configure it *will* be). *Assume* it will not be.

3) Penetration testing is *expensive* in time and money. *Assume* we don't *really* need to do it.

I think I mentioned they were *designed* for nuclear emergency response so I'm guessing the engineers working on them were aware of the special environmental hazards of these sorts of sites.

As it happens I've a working knowledge of the sort of precautions used for space radiation proofing.

It starts with avoiding stages in the chip fab sequence that are especially vulnerable to ionising radiation and particle damage. Actmel are know for supplying devices (especially FPGAs) to use this approach. SOS and SOI high resistance substrates also help.

Follow on guidelines relate to chip layout and spacing certain elements far enough apart so they do not interact. At subsystem level it moves into redundancy and voting systems to detect flipped bits and/or stuck at nodes. About this you'll be looking at watch dog timers to re-boot the whole thing if it goes haywire. Lastly if that *still* doesn't cut it they put it in a solid metal box.

Rad hard versions of various processors are available. Systems demonstrating operation at krad levels (give 1 rad is the energy level needed to kill mammalian cells that would certainly kill humans) exist. The SPARC architecture (being public domain) being a regular candidate for this and at *least* up to at least 400Mhz parts are available. Perhaps not powerful enough to self-navigate around a wrecked nuclear reactor but quite capable of feeding images and receiving control commands through a fibre optic link.

Rad hard electronics is a small, specialized area and prices are high. Experimenters working on both space instruments and those for use use around particle accelerators have *long* been studying ways to use cheaper parts to save money while *some* companies have looked to offer radiation resistance by tweaking their processes as long as they don't have to warp them too far.

@Marcus Aurelius

"Can a plant be designed such that if absolutely everything gets screwed, it will die/close down in a manner which does not place anyone outside the plant at risk?"

You're a bit behind the curve. They are sometimes referred to as "Walkaway" or "inherently" safe designs and *some* of what have been called Gen IV designs have this approach as well.

What you're talking about is designing in thermal/chemical/nuclear/mechanical feedback mechanisms that shut it down instead of making the situation worse.

BTW the BWR's have *some* of this built in. Water level goes downs, moderation goes down (water is both moderator and coolant) -> reactivity goes down. Unfortunately *not* fast enough or far enough so that (in the worst case) air cooling is good enough to dump the residual heat.

Other tactics would (if implemented, AFAIK no one has *built* a reactor to these designs) include using thermal balance in that hot water rises, cold water falls. Too much heat lightens the water (or other fluid) in the reactor and pulls in a supply of cold coolant using natural convection (some US submarine reactors are *reputed* to use this, at least as an optional mode as it is extra quiet but those who know won't be talking). The cold coolant could also be dosed with Boron to really shut it down fast.

It's a chip scale heat pipe

When you scale down the heat pipes you have to scale down it's components. Note that normal scale heat pipes have been described as having a thermal conductivity 600x that of an equivalent thickness Copper bar, so only 2x is not very good (but one of the issues with this sort of micro/nano engineering is the unexpected *highly* non-linear scaling effects. The point at which "drops" of water are more accurately clusters of water molecules, for example).

"Phase change." Would it seem less high tech if we called it "boiling" and "condensing" instead?

Because that *is* what is happening,

I'm guessing (because lets be frank this is not a very tech article) a *lot* of the clever stuff is the *manufacturing* of the thing, rather than the idea itself.

The *implication* would be the pipe (or pipes) mfg process could be *integrated* into the chip fab process itself. Chilling out those monster power transistors on RF or power devices, as well as keeping the SiGe Copper interconnected processor cores of your next gen processors from meltdown

*if* correct, that would make it as big a step forward as the introduction of Copper (by IBM) as an on chip interconnect and SiGe for very fast chips.
