Chapter 1385 Tritium Proliferation Module


    One week later.


    The magnetofluid laboratory of Torch Laboratory is still on. Chang Haonan takes off his protective mask and stares quietly at the heating-up helium-cold solid ball bed.


    Liquid lithium flows slowly in the annular pipe, glowing a weird luster under the dark red warning light, like a metal snake trapped in a quartz tube.


    After a fulfilling and idle week at home, he finally returned to the lab with no time to start the next stage of work—


    Of course, the superiors could not allow him to build a nuclear reactor in the urban area of ??Beijing, but some radioactive research related to nuclear technology is still fully conditional.


    “Teacher, the vibration spectrum of the No. 3 circulation pump has been analyzed.


    "A doctoral student in a dark blue one-piece uniform suddenly poked his head out of the equipment, and there was still a little metal powder on the file board in his hand:


    "The abnormal vibration at 0.87Hz is enhanced by 37% compared to yesterday. Do we need to shut down to check the magnetic bearing?"


    Chang Haonan glanced at the real-time monitoring screen, and the temperature gradient of the magnetic fluid channel was fluctuating in the green safety zone.


    "No need...the test conditions today are different, it is normal to have a larger vibration. In addition, increase the sampling frequency to 200kHz, and let Teacher Li take you to the second floor of the underground to get a laser Doppler vibrator."


    He said while signing a scribbled timestamp on the duty record book, and then added:


    "Also, remember to apply dimethyl silicone oil to the vacuum flange. The last time the helium mass spectrometer leak detector was blocked by lithium steam."


    At this moment, Li Yabo happened to walk in from outside, holding a device in his arms:


    "I''ve brought it over... In addition, teacher, there is a Peng Jue outside who wants to see you first, saying that he had made an appointment with you yesterday."


    Chang Haonan was stunned and stopped his actions:


    "Please invite him in..."


    When he pushed open the glass door of the conference room, Peng Juexian was hanging his coat on the coat rack, and the woolen fabric rubbed against the metal hook and made a rustling sound.


    An officer following him was holding an encrypted document box, and the nuclear industry logo embroidered on the collar was looming in the shadows.


    "Old Chang, I read the weekly report you sent me two days ago."


    Peng Jue first took the password box and opened it quickly:


    "The tritium retention rate of the lithium circulation system is two orders of magnitude higher than the theoretical value, which cannot be explained by the abundance of lithium-6 isotopes."


    "Mr. Peng, you are concerned about it and it''s a mess..."


    Chang Haonan took out two cans of salt soda from the constant temperature cabinet. The squealing sound when the can was opened was particularly clear in the silence.:


    Our neutron source intensity is only 10n/cms. It is calculated based on the reaction section of trilithium isotopes. This is the normal data range. ”


    "You have raised the tritium pool in liquid lithium."


    Peng Juexian suddenly said.


    He took out a notebook from his bag and opened it to the place he wanted. Obviously, he had read it a lot during this period.


    A printed map is pasted on it, and the location of a feature peak is heavily circled by a red pen:


    "Isn''t this a desorption peak of deuterium-tritium mixture?"


    He pointed his fingers on it, and a little doubt appeared on his face:


    "Also, the XPS spectrum of the Synchronous Radiation Laboratory shows that there is a lithium tritiated deposition layer on the surface of your circulating pump impeller..."


    The laboratory fell into a strange silence.


    Chang Haonan could hear the buzzing of the vacuum pump from the material analysis room next door, and the newly installed Shanghai Light Source Branch Station was undergoing preheating and debugging.


    "When the shield was replaced before, the pressure sensor of the circulation pump did detect abnormal fluctuations." He finally spoke, his fingers unconsciously rubbing the working card on his chest:


    "But you have to know that the fuel consumption of our core is less than 0.01%, which is completely laboratory-level data. You can''t compare it with the standards of pilot or even industrial level... Forget it, you can change your clothes first. Come to our laboratory and have a look..."


    …


    "Is this the closed-loop magnetofluid system you have optimized?"


    Peng Juexian''s fingertips swiped across the console parameter interface, watching the count of magnetic flux beating regularly at the edge of the screen.


    "I remember telling you before that the key reason why we conduct research on lithium is to shield neutrons... The tritium produced will of course strengthen the plasma power generation process, but even under the ideal situation, the amplitude is only roughly 3-5%, so it will not be specifically enriched."


    Chang Haonan adjusted the angle of the waveguide and added a few seconds later:


    "Of course, we can also add the research topics... But Lao Peng, you have to give me enough reason."


    The other party was a little anxious when he made an appointment yesterday, and today he even wrote his eyebrows on his face.


    Obviously something is wrong.


    Peng Juexian didn''t hesitate, but just sighed and replied:


    "Early next month, the International Thermal Fusion Experimental Reactor (ITER) Council will hold a working meeting to determine the test schedule for the tritium proliferation test modules of helium cold ball beds in various countries..."


    The laboratory''s ventilation system suddenly increased its power and drained the last slight ozone smell.


    The newest ⊥Xiao⊥Speak⊥Send⊥Six⊥9⊥Book⊥⊥⊥⊥Back⊥⊥⊥⊥!


    Chang Haonan''s finger paused on the keyboard for half a beat, and the code compiler''s cursor flashed regularly on the screen:


    "So, are you going to develop new tritium proliferation technology?"


    Peng Jue nodded first, and the thermos he carried with him made a crisp sound on the metal countertop:


    "At this stage, we are still using lithium oxide and ternary lithium ceramics as the main solid tritium proliferators."


    He took out an experimental data from his notebook three years ago, and the defect density distribution map was like a crater on the surface of the moon:


    "The current irradiation tritium production technology has serious damage defects, such as lithium vacancies, oxygen vacancies, unpaired electrons... and vacancy migration leads to lattice distortion, and tritium atoms are trapped in electron traps formed by oxygen vacancies. Like using a colander to collect rainwater, the ultimate effective retention rate is terrible."


    "So a new solution is needed, but Americans list the data on liquid proliferators as NOFORN (not allowed to be disclosed to foreigners). Of course, this is also normal. No one can disclose this kind of thing at will..."


    The buzzing sound of the server array suddenly mixed into the sound of the rain, Chang Haonan turned the power of the accelerator to standby state, and the display screen was filled with a cold blue light:


    "My neutron source strength is less than one millionth of that of tokamak. We need to accumulate effective data..."


    He looked at the electronic calendar on the wall, and the red numbers showed August 27, 2008:


    "It will take at least 18 months, and the subsequent research process will also be taken into account."


    Peng Jue waved his hand first:


    "The point is not speed, but time window"


    As he said that, he pulled a piece of paper from the side and drew the timeline:


    "ITER is an international project, and for military reasons, countries do not share tritium proliferation technology. They can only use facilities within the ITER framework to test their own tritium proliferation modules, so the schedule is a turnaround... Generally speaking, each The cycle ranges from about 16 to 24 months. If the data in the first test is not ideal, you have to wait for a year and a half to two years before the next test will be conducted."


    Chang Haonan immediately understood.


    If the schedule cannot be accurately aligned, it is very likely that the progress of 1-2 months is delayed for an additional 1-2 years.


    Moreover, if a cycle cannot solve the problem, it is likely that each cycle will have a delay of 1-2 years.


    This is unacceptable to China.


    Of course, controllable nuclear fusion is not bad for a few years.


    However, tritium proliferation technology also involves the power of thermonuclear weapons and the level of miniaturization, which is the focus of the superiors at this stage.
