Chapter 1144: Not a secret

At this moment in Pakistan, if mobilizing the power of the whole country can only keep a secret and unconditionally protect one person’s safety, then there is no doubt that the "little toy" in Tan Zhenhua's mouth is that secret and can be protected. The person is not President Mohammed. Zia. Huck himself, but Dr. Abdul Kadir Khan!
This name, in Pakistan, is the top secret among top secrets!
Abdul Kadir Khan was born in 1936 in the city of Borpar, Indy under British rule. After the partition of India and Pakistan, his family moved to Pakistan due to religious beliefs.
In 1960, he graduated with honors from Karachi University with a Bachelor of Science degree in Engineering, and then went to Berlin, the capital of West Hans, for further studies, and then went to other European countries to study, and obtained a master's degree from Holland Delft University of Technology. In 1972, he received his doctorate degree from Catholic University of Louvis, Belgium.
On May 1st of the same year, Dr. Abdul Kadir Khan, who was 36 years old at the time, was recommended by his supervisor and joined the famous "Physical Dynamics Research Laboratory" in Amsterdam.
At this time, the laboratory is conducting an important research-the development of a centrifuge for uranium enrichment.
This research project was initiated by Ulenco, a leading European nuclear power plant construction and operation company, and was supported by the governments of Britain, West Hans, and the Netherlands. The goal is to ensure that these three countries can guarantee independent fuel sources in the field of civil nuclear energy. To get rid of the dependence on American technology.
Dr. Abdul Kadir Khan has worked in this laboratory for more than two years, during which time he acquired a large amount of uranium enrichment technology with various excuses and means.
On December 15, 1975, he and his family left the Netherlands on the grounds of returning to Pakistan to visit relatives and never returned because he had accepted a new mission.
Seeing this, I believe that all readers and students already know what kind of mission Dr. Abdul Kadir Khan shoulders.
To be honest, in terms of the security environment facing Pakistan Railways at that time, the development of nuclear weapons was indeed the common voice of the whole country.
Because, just one year before Dr. Abdul Kadir Khan’s return to China, Palestine’s arch-enemy, Indi, implemented the code name at the Pokran base in the desert of Rajasthan on May 18, 1974. The nuclear explosion test for "Buddha Smile", although this nuclear explosion test is hard to be judged as a success, it is a very obvious signal.
The pressure of Pakistan Railway can be imagined.
So, whether it is Ali before. The Bhutto government is still Zia at this time. The Huck government has given the team led by Dr. Abdul Kadir Khan the maximum support, from funding, personnel to materials, the green light all the way.
All of this was carried out in a state of extreme secrecy, which is the top secret of Pakistan Railways, none of them!
But now, at this moment, Tan Zhenhua screamed!
This is no wonder that it is as calm as President Zia. Huck, as capable as the Minister of Equipment Mahmoud, was going to lose his attitude for a while.
And while the two of them were still exchanging suspicious eyes with each other, Tan Zhenhua had already quietly continued: "Mr. President, Mr. Minister, don’t forget, when Dr. Abdul Kadir Khan was still there." When he was working in the Physical Dynamics Research Laboratory, some of his abnormal behaviors had already attracted the attention of the Dutch government. In early 1974, the Dutch Ministry of Economic Affairs issued a ban on him to "keep away from the centrifuge." Certain monitoring measures were also taken against him, and when he returned home without saying goodbye, although this kind of monitoring measures had to change the way, it never stopped. You have to know that there are some things in the monitoring methods of Americans Underneath, there is no way to hide."
After strengthening his mind and stabilizing his mind, Zia. Huck had to ask: "Eric, what do you know? And, how can you be sure that the Americans can monitor?"
By saying this, he undoubtedly has indirectly admitted that what Tan Zhenhua said earlier is true.
"The principle of fission bombs is not complicated. Let's put it this way. According to the current teaching level, a qualified science graduate who has received a complete high school physics education understands the principle." Tan Zhenhua chuckled his lips and said: To actually manufacture it, many engineering and technical difficulties need to be overcome. One of the most important is how to obtain enough fissile materials."
"Ok?"
"Theoretically, uranium-235, plutonium-239, californium-251, and curium-247 can all be used as fissile materials, but everyone knows that the latter two elements are too expensive to make atomic bombs. The value of californium-251 may be much higher than the value of the target you want to destroy. For example, californium-251, a microgram in the international market costs about 10 US dollars, and it takes about 5 kilograms to reach the critical value of continuous fission. Then this atomic bomb photonuclear material The price of uranium must be 50 billion U.S. dollars, and I am afraid that no country can afford it. Therefore, based on these realities, relatively "cheap" uranium-235 and plutonium-239 have become the nuclear materials of choice for atomic bombs."
After a pause, he looked at the dumbfounded two audience members and then said: "Regardless of which of these two materials are used, there is a material purification process. Weapon-grade nuclear materials require a purity of more than 90%. %, and the purity of the nuclear materials used in power stations is only about 3%. Take uranium as an example. Of the metallic uranium extracted from uranium ore, only 0.7% is uranium-235, and the rest are useless uranium-238; The preparation of plutonium-239 requires you to first have an RBMK uranium-graphite reactor and then bombard the uranium-238 with slow neutrons. However, in this process, a large amount of plutonium-240 will inevitably be doped. Plutonium-240 is a typical "bad material". Too much doping will cause the fission bomb to explode without sufficient reaction. The process of separating plutonium-239 and plutonium-240 is too complicated, so you should go for Abu The uranium enrichment technology route obtained by Dr. Durer Kadir Khan from the "Physical Dynamics Research Laboratory" is to separate uranium-235 with a centrifuge."
At this time, no one was in favor, Tan Zhenhua had to continue to say: "Uranium-235 is separated from a large amount of uranium-238, and the current method is to use the small difference in the quality of the two. It takes 70,000 revolutions per minute. The method of high-speed uranium enrichment centrifuge separation, but this method is actually not very efficient and very energy-consuming. In other words, in order to obtain nuclear materials for making a fission bomb, you need to build a large purification plant and After working for many years, you have to equip it with a power station with sufficient power. You can't hide these large facilities at all. The satellites of the Americans can be seen clearly."
After a short silence again, Zia. Huck finally spoke: "Eric, you mean, they knew it already?"
Tan Zhenhua nodded and said: "Yes, Mr. President, you see, I only have a few "friends" of the upper echelons of the U.S. I already know so much. Obviously, for the CIA, the existence of the Kahuta factory has always It’s not a secret, and the reason why they don’t say anything or do anything now, you should know the reason, then the question is-when that turning historical moment really comes? Do you think the Americans still Will you continue to pretend to be deaf on this issue?"
