Chapter 5753 Sister Nian clicked her tongue
Bescia commanded calmly: "Place uranium-238 (U-238) in the nuclear reactor and receive neutron irradiation."
They pay close attention to the changes inside the nuclear reactor.
"After uranium-238 absorbs a neutron, it turns into uranium-239 (U-239)." The researcher responsible for this step immediately reported the information he collected to Bethea.
Bethea made a quick decision: "Black man, conduct the first electron launch."
"OK."
The black man operated the instrument and started the first electron emission experiment.
Bethea looked at the nuclear reactor inside the glass, waiting for the time to pass, and estimated that it was almost done.
She looked past the others and landed on the girl not far away, as if she wanted to draw energy and encourage herself.
She took a deep breath: "Carry out the second electron emission!"
"Okay, Captain."
The black man completed the second electron emission experiment with a high degree of mental concentration.
The person responsible for the third step of the experiment observed the changes inside the nuclear reactor. After seeing the subtle changes, he immediately reported calmly.
"Captain, uranium-239 undergoes two beta decays (i.e. two electron emissions) and is finally transformed into plutonium-239 (Pu-239)."
"Go to the next step."
Bethea is well aware that the plutonium-239 produced is often mixed with uranium and other fission products and needs to be extracted and refined to obtain pure plutonium-239.
Others got busy and started extracting the liquid inside. After the irradiated fuel elements are removed from the reactor, they will be placed in a pool to cool for 2 to 4 months. This can minimize the intensity of radioactivity.
But the Sixth Continent has long had the strongest protective clothing in the world. Through countless experiments, it can block radioactive materials outside the protective clothing.
Therefore, neither Bethea nor other personnel of the Third Laboratory are afraid of the super radiation brought by these things.
They can proceed directly to the next step without waiting for such a long time, greatly shortening the experimental time.
On the first day when Qiao Nian came here, when she was looking around in the laboratory, she fell in love with the protective clothing inside. When she wanted to leave, she wanted to get a few sets to take back to Feng Yu and the others. Master Cheng, or give it to the Jiu Institute to dismantle and study it to see if country Z can make something similar.
She leaned there and heard the black man asking Bethea.
"Captain, which solvent extraction method should we use next?"
Qiao Nian raised his eyebrows. The cooled fuel elements will be dissolved with solvents such as nitric acid to form a solution containing uranium, plutonium and fission products.
Solvent extraction is used to separate plutonium from uranium and fission products. In this process, the difference in solubility of plutonium and uranium in different solvents will be used to achieve separation through extraction and back-extraction steps...
She also wanted to know what method Bethea was going to use to do the next, most important part.
After thinking for a moment, Bethea said: "We should still use the previous Prex process."
"Tsk." Qiao Nian clicked her tongue, her sharp eyes showing a true look, with a hint of waning interest.
Bethia heard this, looked over subconsciously, and frowned. Realizing that she might have done something wrong, she rubbed her brows and wanted to ask. Then she remembered what she had said and opened her mouth and closed it again.
Seeing her hesitant expression, Qiao Nian rarely took the initiative to speak: "Just say what you want to say. I just said that I won't do it. I didn't say that I won't help you if you ask."
