Compromise reached as Linux kernel community protests about treating compiler warnings as errors

itzman

Re: A billion years ago...

Yup. Sure its a faff when you get a null pointer returned from a function and apply a test to it and the compiler says 'but its not an integer' BUT if you explicily cast it to one, the next bloke along compiling onto a 16 bit integer target with a 32 bit address bus at least knows what you were TRYING to do...

Re: The reactor is the right size

The benefits of the small modular reactors being developed worldwide are eaily listed

1. Small reactors can use the cube-square law of heatloss versis size to be safe under passive cooling in SCRAM conditions. At a stroke the cause of the only two core meltdowns of PWRS is eliminated

2. Small reactors can be assembled in factories under controlled conditions and then shipped out for installation, massively reducing build inspection and certification times.

3. Larger outputs can still be achieved by use of multiple units

4. Water coooling may not be needed for smaller units making siting less of an issue.

5. Although less efficient in the use of uranium and especially when compared to fast breeders, there is no shortage of uranium at the moment and its dirt cheap.

Although the bogeyman of man made climate change is pretty much dead in the water in scientific circles, the fact remains that fossil fuel costs both in terms of cash and energy required keep on rising as the low hanging fruits of mining and drilling have all been plucked, and the massive propganada campaign about CO2 has left the ill informed public thinking they need alternatives, and renewable energy - which was esily provable over a decde ago to be unsuitable and not fit for purpose - is now undergoing subsidectomy, there remains only one viable and poltically acceptable alternative - and that is nuclear power of some sort..

And whilst not intrinsically ideal from an overall efficiency and engineering perspective, factory built type approved mass produced small (350MW ) modular pressurised water reactors would use thoroughly known and proven technology - the only thing different is that they would be factory built - and can couple up in as many uniyts as are needed to bog standard steam turbines up to a gigwatta mecahnical output or more. Rolls Royce Trent gas turbine units are already used in multiples in gas power stations feeding steam boilers to drive additional generation capacity in CCGT power stations so the modular technology already exists.

What the public probably thinks (or has been told to think) it wants , is a Heath Robinson array of windmills, solar panels, hydrogen production, grid scale batteries made of unobtanium, transcontinental interconnectors and BEVS using lithium sourced from the imagination - there not being that much around to mine...

What it needs however, is a couple of hundred small modular reactors, driving the grid and synthetic hydrocarbon plants. Nothing in the chemical table beats hydrocarbons for energy density and safety in off grid power.

Except uranium and plutonium of course, and how far we will have nuclear ships powered by very small modular reactors plying the oceans remains to be seen.

Re: Thankfully, the world is simple

Nuclear waste.

1. The longest lived nuclear isotope in the world today is the natural uranium we burn to make nuclear power, thus reducing the total amount of radioactivity in the world.

2. There are ~4 billion tonnes of it in the worlds oceans, yet people get excited when a few pounds of radioisotopes were released into the sea at Fukushima.

3. the longer lived the isotope, the less active and the less dangerous it is. If the Romans had had reactors by now they would have decomissioned themselves.

4. If the Romans had had reactors, their Empire would not have collapsed

5. The science now tells us what we didn't know in the Cold War period, that chronic exposure to low level radiation up to 200msV/year has absolutely no discernible effect on cells. And total dose is not what counts - peak dose is what counts.

6. If reactors were built and waste dispaosal were done to reflect what we now know about radiation - that its about 1000 times less dangerous than those old cold war regulations suggest - as evinced by the zero death count from radiation at 3MI and Fukushima and the piddling death count at Chernobyl - less than a hundred people, all exposed to massive single doses fighting fires - then most of the cost would vanish.

Nevertheless this project is, while sexy, not really commercial. We dont need advanced reactors, we need cheap reactors, and that means trying to meet regulatory ratcheting driven by anti-nuclear sentiment paid for by other energy interests with simple cost effective boring ordinary 50 year old technology that is developed to be quick to manufactire and install, and cheap.

If the nuclear industry spent one percent of the money it spends on trying to meet insane and ever moving safety goal posts, on educating people on how safe it was...

https://world-nuclear.org/getmedia/bdfff1aa-1a50-4793-9362-a95119b2307d/recalibrating-risk-report.pdf.aspx

Having said that, heatbanks as a way of storing heat energy before conversion to electricity are interesting and may be more cost effective at supplying peak demand than building either pumped hydro (if handy nesaby mountains and water exist) than overcapacity of reactors running below full capacity much of the time.

What is disppointing in reading posts by El Reg readers is that one would have expected the readership to be both techically savvy and capable of researching what this project actually is, and yet the majority of comments betray utter ignorance of either.

Re: Proper Generation IV reactor design

a molten salt heat bank is not lightning fast load following since it will still be used to generate steam for a turbine.. unless they use flash steam...which no other power station to my knowledge ever has.

It will ramp up and down as fast as a coal burner, maybe even a CCGT, but not as fast as hydro.

A well manged PWR is almost as fast.

itzman

Re: You know what

Natrium isnt a molten salt cooled reactor.

Its a molten sodium cooled fast breeder reactor plus a heatbank that stores thermal energy in molten salt to allow it to modulate its output above and below the reactor output in order to provide dispatchable load following without having to have a pumped storage hydro scheme coupled up. Batteries of course are completely unsuitable for grid scale storage

At an intelligent guess I would say it will mostly work eventually long after small modular reactors of bog standard design have become the de facto standard, and more money than even Gates can afford has been spent on it.

itzman

Re: Go for it

Really there is no need to invent or develop massivly new reactor designs.

What Rolls Royce and others are doing - production engineering small, and hence passively coolable under Scram, bog standard type approved pressurised water reactors for mass production at low cost with lifetime storage of used fuel (until polticians can decide what to do with it) is the low cost low risk option - is by far and away what we need right now.

Natrium is a complex liquid sodium cooled fast breeder. Dounreay effectively. Expensive, technically tricky, and full of the same problems as Gen II reactors.

Throw enough money at it and I am sure it will work eventually, but it seems to be repeating the same mistakes that the UK nuclear power program made - letting scientists create a better mousetrap rather tnan letting engineers cost reduce and streamline production of a perfectly adequate one

FYI: Today's computer chips are so advanced, they are more 'mercurial' than precise – and here's the proof

well its obvious

that as a data one gets represented by e,g, less and less electrons, statistically the odd data one will fall below the threshold for being a one, and become a zero, and vice versa.

or a stray cosmic ray will flip a flop.

or enough electrons will tunnel their way to freedom....
