The actual discovery of the element plutonium came the year before, however, when neptunium-238 was formed.

You see, the uranium or plutonium fission-bomb's been obsolete for over four hundred years.
I wonder if he mightn't have some idea of what elseplutonium can be used for, beside generating power.
The plutonium bomb, from a military standpoint, was as obsolete as the flintlock musket had been at the time of the Second World War.
There would be no problem of producing fissionables--we've been scattering refined plutonium over this planet like confetti.
As soon as Orgzild would hear about the possibility of making a plutonium bomb, he'd set up an A-bomb project, and don't think of it in terms of the old First Century Manhattan Project.
We've been compelled, because of the lack of natural fuel on Ullr, to set up nuclear power reactors and furnish large quantities of plutonium to the geeks to fuel them.
I wonder if he has any idea of what else plutonium can be used for?
Hey, you're not thinking of selling Amaterasu plutonium and Beowulf gadolinium, are you?
That's where we get our plutonium and our power units.
Beside plutonium and radioactive isotopes, she carried a general cargo of the sort of luxury-goods unique to Beowulf which could always find a market in interstellar trade.
Beowulf is lousy with fissionables; they'll give us all the plutoniumwe can load, in exchange for gadolinium, which we sell them at about twice Sword-World prices.
We trade plutonium on Amaterasu for gadolinium, and get it for about half Sword-World prices.
Of course, there's still India, which has plenty of unrestricted plutonium and they've even claimed they could make a bomb in a month.
Their plutonium-reprocessing plant at Dimona extracts plutonium from the spent fuel in their research reactor there, and CIA claims they've got at least two hundred strategic nuclear weapons.
Normal plutonium bombs need eight kilograms of the stuff, but we think they've come up with a sophisticated way to make one with five.
Work was already going on in the power plant; a gang under a slim young man whom Anse introduced as Mohammed Matsui were using repair-robots to get canisters of live plutonium out of a reactor.
So the robots began tearing out reactor-elements, and removing plutonium slugs no longer capable of sustaining chain reaction but still dangerously radioactive.
Illustration: Fisheries biologists studying hatchery fish reared in water containing radioactivity from the Hanford plutonium reactors.
When a nuclear device is detonated, the release of energy is due to the fission of uranium or plutonium atoms or to the fusion of hydrogen atoms.
The Hanford studies were started before plutonium production was begun in 1943, and findings on industrial stack-discharge rates established patterns for meteorological programs at other sites.
A test of the plutonium implosion device was necessary to determine if it would work and what its effects would be.
Seaborg at the University of Chicago; intense neutron bombardment of plutonium in nuclear reactors.
By 1944 sufficient plutonium was available from uranium piles (reactors) so that it was available as target material for cyclotrons.
You are as funny as a plutonium crutch," Zahooli says.
He has to be hit once more which is enough and we tie him up with rope that looks like it was made out of plutonium filaments.
This little chuck-walla's hotter than a plutonium pile!
And to think of those damn fools on Earth with their plutonium piles!
This particular bomb design used five pieces of plutonium which were driven together to form a ball.
At first Rip had worried about the two pieces of plutonium making a good enough contact, but Kemp’s skillful hand and precision eye removed that worry.
Their single five KT bomb contained at least enough plutonium for two critical masses, if brought together inside a good neutron reflector.
They put the thorium block which contained the plutonium into the hole, the plutonium facing outward.
Rip took a block of plutonium from Dominico and handed it to Kemp.
When electric current fired the rocket head, the thorium carrying the plutoniumwedge would be driven forward to meet the wedge in the back.
He slid the thorium-plutonium block into the tube, took a rocket head from Santos and used it to push the block in farther.
The torchman finished fitting the plutonium and carried the block to the tube opening.
First, two or more pieces of plutonium large enough to form a critical mass.
Rip added it to the front of the plutonium wedge along with a piece of beryllium from the bomb, and Kemp welded it in place.
Kemp sliced another round block of thorium out of a near-by crystal and fitted the second wedge of plutonium into it.
Two or more correctly sized pieces of plutonium or uranium isotope, when brought together, formed what was known as a critical mass, which would fission.
However, final preparations for the test, which included the assembly of the bomb's plutonium core, did not begin in earnest until Thursday, July 12.
The idea of using some kind of container for the Trinity device was based on the fact that plutonium was extremely expensive and very difficult to produce.
The Nagasaki weapon was a plutonium bomb, similar to the Trinity device, and it was nicknamed Fat Man.
After assembly, the plutonium core was transported to Trinity Site to be inserted into the thing or gadget as the atomic device was called.
Jumbo was the code name for the 214-ton Thermos shaped steel and concrete container designed to hold the precious plutoniumcore of the Trinity device in case of a nuclear mis-fire.
Then a spacious room in the northeast corner of the house was selected by the Project personnel for the assembly of the plutonium core of the Trinity device.
He slid the thorium-plutonium block into the tube, took a rocket head from Santos, and used it to push the block in farther.
At first Rip had worried about the two pieces of plutonium making a good enough contact, but Kemp's skillful hand and precision eye removed that worry.
Rip added it to the front of the plutonium wedge, along with a piece of beryllium from the bomb, and Kemp welded it in place.
Kemp sliced another round block of thorium out of a nearby crystal and fitted the second wedge of plutonium into it.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "plutonium" in a variety of sentences. We hope that you will now be able to make sentences using this word.
