Re: Hinkley Point Nuclear Plant may have hit a major stumbling block

So another good reason for us to get out of the EU.

Re: Hinkley Point Nuclear Plant may have hit a major stumbling block

I still don't understand why BNFL was sold off to foreign operators in the first place, there would be no such objection possible if it was still an internal state owned and operated company, still that's another great decision we have labour to thank for inflicting upon the company ......

Re: Hinkley Point Nuclear Plant may have hit a major stumbling block

stumbling block now confirmed http://www.theguardian.com/world/2015/jul/06/austria-files-legal-complaint-against-uk-hinkley-point-... and the reactor design has also hit major problems http://www.theecologist.org/News/news_analysis/2859924/finland_cancels_olkiluoto_4_nuclear_reactor_i... so it looks like nuclear in the UK has come to a grinding halt

What we need is a few more of these...

Construction phase now underway. And it will be finished in five years.

Buy the design of a Thorium reactor from China or India and build our own. Much less hazardous and thorium is easily obtained.
Now Zen, but a +Net residue.

Re: Hinkley Point Nuclear Plant may have hit a major stumbling block

we need a uranium based reactor in order to ensure we have a supply of weapons grade waste material though, if we slip up and stop maintaining the nuclear deterrent then we put the country at risk particularly now that other nations are starting to adopt nuclear weapons, thorium based reactors are great because they are much cheaper and safer to run but they don't provide the requisite materials for maintaining the arsenal.
the news about Hinckley C is good however because the last thing we need is a giant reactor anywhere in the UK, a single small unit will do the job just fine, and using the existing design from the original reactors will provide us with a proven technology that we already own the licence for making it a cheap and relatively quick build option that could be up and running in less than 3 years, the real challenge will be investing the 13 billion worth of subsidies effectively in new renewable options to produce the power required for the country going forwards, and whilst I understand the concerns with nuclear energy smaller units don't come with the same degree of problems that larger units do.
hopefully they will revert to the original idea of just replacing the reactor core at Hinckley A and be up and running within the next 5 years, lay in the foundation work for closing down and replacing each of the other reactors (with like for like) on the same site currently in use and we can secure a baseline energy supply for the UK from a multitude of small units rather than having 1 giant unit that posses a risk to the entire country should a Manhattan situation occur

Re: Hinkley Point Nuclear Plant may have hit a major stumbling block

Buy it from China ?
I Would get them to build it as well in half the time it would take us to build it....... just make sure the software to run it is a British Project.

If the chinese can't build something as simple as a 3-port HDMI switch, would you really want then building a potential chernobyl in your back yard?? Shocked

The UK has a stockpile of 112 tonnes of plutonium. How many countries do you need to level?

Re: Hinkley Point Nuclear Plant may have hit a major stumbling block

the stuff denatures over time and drops from being weapons grade to being nothing more than a lethal paperweight, for the proper fission/fusion blast you have to refresh the material every few years and for that you need a reactor and various other bits n bobs, 112 tones is barely enough to send a probe to mars and back utilising a nuclear pulse engine (which the majority of stuff is using for the last few years for fast exoatmospheric travel) the Rosetta probe utilised 150 tonnes of fissile material to generate the thrust required to catch the comet never mind the amount its burnt whilst slipstreaming the thing in the months since it arrived.
what we will require going forwards is closer to 200 tonnes just for the routine replacement of warhead material, rember of course that whilst you might only need 10 kg per missile there are more than 80 rockets in each boomer and each of those has either a 5 or 12 shot merv then there are the fixed ground silo's that have up to 24 rockets with each capable of carrying up to 48 x 10kg multishot merv warheads, and lets not forget that we utilise anti armour rounds that are depleted uranium based and we also have up to 100k 1 pound tacticle warhead delivery systems, all of which need regular maint to prevent them developing leaks etc.
100 tonnes a year for as long as we need to maintain the deterrent will be a rolling stock that's being utilised quite regularly, and will require the ability to regularly replace it with fresh stock rotated out of the old warheads.

Really?  The published info regarding the Rosetta probe suggests that it uses a bi-propellant fuel and oxidiser system.  As ever, you presumably are able to provide references to the use of the hypothetical nuclear pulse engine?
Thought not...

I always thought they used Plutonium 239 for hydrogen bombs and that has a half life of 24,100 years
Pu 238 is the one used for powering spacecraft etc. and has a half life of 88 years
As an example Cassini is powered by 32.7 kg of plutonium-238—the heat from the material's radioactive decay is turned into electricity.

Re: Hinkley Point Nuclear Plant may have hit a major stumbling block

the problem isn't the half life but the amount of ionisation that occurs which changes the explosive mass properties.
mini reactors powered from the rate of decay used in low speed units like cassini are fine the problems come from the high speed units trying to generate enough propulsion, which is where the pulse engines come into their own, micro mass fission through a directed tunnel is easy to control as your essentially dripping fissile material into a ram jet once the conventional solid/liquid fuel filled boosters have achieved the speed required for it to work.
as to the type of fissile material utilised it all depends on whats available, the yanks have /had a lot of low grade plutonium spun out of the high grade stuff and they found a way to use it for things like cassini rather than consign it to yet another barrel for dumping in the earth for which they are to be congratulated its a shame more countries don't do similar things, intermediate grade material can be used for pulse engines, but you need more of it as your constantly using it up than in a slower unit.
