Sample translated sentence: All nuclear warheads contain the fissile isotopes of plutonium or uranium, and these all emit radiation, either spontaneous neutron or gamma radiation ↔ 所有核弹头都含有钚或铀裂变同位素并且都排放辐射,不是自发中子就是伽马辐射。 fissile...
A nuclear fuel must contain fissile nuclei. One can use any of thefissile isotopesof uranium andplutonium. The fissile materials are the odd-Aeven-Znuclei (Ais the atomic number andZis the nuclear charge). Important examples are233U,235U,239Pu, and241Pu. They undergo fission when struck wit...

A series of measurements of uranium/plutonium rods performed in the CESAR reactor, from 20 to 400掳C, is analyzed, and modifications of the absorption and fission cross sections of plutonium isotopes are proposed.doi:10.13182/NSE72-A22488B. Laponche...
Chemical, radiation, and isotopic methods of denaturing are reviewed and placed in perspective, especially with regard to other nonproliferation safeguards and alternatives. Particular attention is given to even-isotope plutonium denaturants, taking into account recent emphasis on 238Pu. Commercial and ...
7、The uranium or plutonium isotopes are referred to as "fissile," which means we can use them to induce fission by bombarding them with free neutrons.(铀或钚的同位素被称为裂变材料,即我们可以利用自由中子去轰击它们来产生裂变反应。) 8、The important way to control the proliferation of nuclear ...

How much does 1 kg of plutonium cost? Since the energy per fission from plutonium-239 and uranium-235 is about the same, the theoretical fuel value of fissile plutonium can be put at $5,600 per kilogram. Reactor-grade plutonium also contains non-fissile isotopes, reducing its value to abou...
Plutonium isotopesPlutoniumA rapid method for nondestructive assay of Fast Breeder Test Reactor (FBTR) fuel pins has been demonstrated using the two-step process of high-resolution gamma-ray spectrometry for isotopic composition measurement followed by neutron well coincidence counting for total plutonium...
D'autre part, par la mesure du nombre de neutrons retardés, on peut déterminer la teneur de la matière fissile dans les différents isotopes du plutonium et de l'uranium. On a représenté sur la figure 4 un deuxième exemple d'application d'un dispositif de contrôle de criticité de...
