Five hours later, the technology simulator: "turbine pump assembly simulation operation failed."

    Du Xingyu saw that it was already 9 p.m. and it was getting late. He had to wait until tomorrow.

    "I''m so hungry." Du Xingyu was lazy and had been in the simulation experiment. He habitually forgot to eat dinner.

    "It''s too late for dinner..." Du Xingyu walked out of the office, thinking about something to fill his stomach, and a man came up.

    She wore the white protective clothing of the scientific research institute, her long hair was tied up, her makeup was light, and her jade face was slightly tired. Even the simple and monotonous protective clothing and tired look are difficult to hide that touch of youth and beauty. Male colleagues passing by couldn''t help but look at it more.

    This is the intern in the group, Du Xingyu''s classmate, Xu Lianqiu.

    Du Xingyu couldn''t help feeling. Sure enough, people with high appearance look good in everything!

    "Chief engineer Du!" seeing Du Xingyu, Xu Lianqiu looked happy, his spirit seemed to rise, and shouted with a little ridicule.

    "Don''t tease me." Du Xingyu smiled. "Why, it''s nine o''clock in the evening and hasn''t left yet. Do you work overtime today?"

    "Yes!" Xu Lianqiu shrugged and said, "it''s not just me. Everyone has been working overtime recently."

    "There''s no way. The progress can''t fall behind. Work harder now and it will be better in the future." Du Xingyu knows that the main reason for everyone to work overtime comes from him. His R & D progress is too fast. Everyone must go all out to keep up with his pace!

    "Haven''t you eaten yet? Here!" Xu Lianqiu opened the small box he was carrying. There were several lunch boxes in it.

    "How do you know?" Du Xingyu said in surprise. "I''m worried about what to eat!"

    "Who in the research group doesn''t know that you miss the meal every day?" Xu Lianqiu glanced at him and said, "the word sleepless is you. Let''s go!"

    "Did you bring it for me?" Du Xingyu asked in a low voice.

    "It''s not..." Xu Lianqiu looked a little flustered and immediately said, "the canteen aunt said you''ve been missing the meal and left it for you."

    "Hey... Bai is happy!" Du Xingyu deliberately sighed and said, "aunt is true love!"

    "Less poor! Hurry to find a place to eat!" Xu Lianqiu said shyly when he saw the passing researchers looking over.

    ……

    Du Xingyu failed many times on the nuclear powered rocket thruster. The accumulated more than one million energy points are almost exhausted!

    Fortunately, within the planned time, he finally completed the complete design of the nuclear powered rocket propeller.

    Now, we only need to manufacture the components of the nuclear powered rocket propeller according to the drawings, add the radiation protection components made by other groups, and install the emergency treatment equipment on the rocket, and a brand-new nuclear powered launch vehicle can be manufactured!

    "Ladies and gentlemen, please work harder these days. I''d also like to ask Mr. Tang and Mr. Zhou to hurry up and make nuclear powered rocket thrusters with the help of the Institute of nuclear power and the Institute of atomic energy." Du Xingyu arranged in the conference room.

    "Xia and your team began to install radiation protection devices and coatings on rocket bodies this month to improve the nuclear fuel control system."

    "Other groups, try to keep up with the progress, and report any problems in time!"

    "We must complete the task!" people said one after another. Many of them can''t believe that their R & D progress will be so fast.

    Space technology, spacecraft, rocket research and development, time units are calculated in years! Even the products in the experimental stage need to be manufactured in a year or two, not to mention this unprecedented nuclear powered rocket.

    But with Du Xingyu, the progress was pulled fast. The problems that annoy them can often be solved in a day or two.

    Now people in the Institute look at Du Xingyu like God. It''s so divine!

    The busy work began again. With the cooperation of other scientific research institutions, the nuclear powered rocket propeller was successfully manufactured in one month.

    In the nuclear protection experimental workshop of Huaxia Nuclear Power Research Institute, people are wearing radiation proof clothes and waiting for the first start-up test of nuclear powered rocket thrusters.

    This is the most critical part. Other components, mechanisms and systems have basically been tested successfully. As long as the propeller test is completed, the nuclear powered rocket will be completed!

    "I hope I can succeed once," he Jingcheng said to himself, looking at the huge nuclear powered rocket thruster.

    "The probability of success is more than 90 percent!" said the gray haired Tang Junwen. "Our nuclear power research institute has repeatedly deliberated and demonstrated the power system of this rocket propeller. The simulation experimental data show that there is no problem. It even brings a lot of valuable information to our nuclear power research!"

    "I also believe it can succeed!" Zhou Ziang said. "Xiao Du uses'' americium ''instead of'' uranium ''and'' plutonium ''atoms as raw materials for nuclear reactors. The critical mass of americium atomic fission reaction only needs 1% of uranium and plutonium, and once the reaction occurs, it can continue. This can make the rocket thruster run stably for a long time."

    "Everyone knows this truth. It is valuable that he can find a way to control the americium fission reactor."

    "No, it''s about to start."

    Everyone calmed down and stood outside the protection laboratory, ready to open.

    "Three, two, one, turn on the controller!" as he Jingcheng gave orders, the controller in the propeller was turned on.

    The controller will adjust the special americium atomic reactor and the control rod used to slow down neutrons.

    Once the nuclear fission reaction begins, it will produce a chain reaction. If you want to control, you have to use a control rod to isolate the reaction. The isolation degree of the control rod can control the speed of nuclear fission reaction, so as to control the propeller.

    During the test, the whole process is remotely controlled electronically in the protection room, which can ensure safety even in case of accidents.

    "Controller turned on!"

    "The radiation field is increasing..."

    Through the electronic screen, people can see clearly that the nuclear powered rocket propeller has begun to operate. Nuclear fission reaction produces a large amount of heat energy, and the efficient heat exchanger converts these heat energy into other energy. In order to test, it has been transformed here. These heat energy are converted into mechanical energy, and then drive the generator to run.

    If it is on a rocket, these heat energy will become the power for the rocket to take off!

    "Data monitoring!"

    "The reaction is stable and the radiation field is stable."

    "The control system is stable, and the regulation reaction efficiency test is being carried out. The power is increased by 30% and successful; the power is reduced by 50% and successful..."

    "Gas pollution detection, gas purification system is normal, no radioactive particle overflow is detected..."

    As the green light of the exhibition lights up, people''s faces become more and more relaxed and happy. They know that today they will make history with their own hands!
