(LEAD) N. Korea completes preparations for nuclear test
(ATTN: UPDATES in paras 1-6; CHANGES headline)
By Kim Eun-jung
SEOUL, Jan. 23 (Yonhap) -- North Korea has completed all technical preparations for a nuclear test and can carry it out in a few days if it makes a decision, a South Korean intelligence source said Wednesday.
North Korea had dug up a tunnel for a test at its Punggye-ri nuclear test site, but the tunnel has now been plugged with dirt and concrete, the source said, suggesting that all measuring and other equipment has already been installed inside.
I’m more interested in how far they are from DC....
U235 is much easier to produce than plutonium.
There is a reason that China’s first bomb, South America’s bomb, India’s bomb, and Pakistan’s bomb were EU.
The primary benefit of a P239 bomb is they can be much smaller and boosted with fusion. If you goal is to blow up a city, you don’t need tactical weapons, just strategic.
Hence, why counties that have need for tactical nukes (e.g., US, Israel (shh!), England, and Russia) are the P239 business.
The arabs just want to nuke whole cities.
As I understand it... plutonium is a waste byproduct of light water and (esp.) breeder reactors. The primary challenge with plutonium is it cannot be processed like uranium, which which when bound to florine produces uranium hexaflouride gas suitable tor the centrifuge. The presence of plutonium240 interrupts the nuclear chain reaction because of high spontaneous fission rate (more neutron activity), thereby increasing risk of spontaneous detonation - a Bad Thing :-)
That's why Pu needs the implosion mechanism.
The Arabs/Koreans/other nuclear yahoos should be well-served with the U235 gun mechanism (and would of course be well-served by our assymetrical retaliation using U235 and Pu239-derived weapons).
The arab bomb design is not a gun mechanism.
It is an implosion device using U235.
Weird. I wonder why.
“Weird. I wonder why”
Because, while a U235 implosion device is larger than a comparable yield Plutonium bomb, it is much smaller than a gun-type weapon and requires far less U235 for a viable warhead.
In short, easier to deliver on a missle, can make more with less.
Not weird at all.
Thanks for the explanation. Makes perfect sense now.
