Are there any friends who are involved in nuclear power!

Look at the structure – if it’s something you’ve never encountered before, for stainless steel materials, irradiation should not be a problem. As for shock resistance, you can give it a try yourself; just conduct a free-fall test. If it still works, then it’s fine, right?:lol

After irradiation aging, seismic resistance tests are conducted. It seems not very useful; ‘good’ or ‘bad’ isn’t really the right way to describe it. If it is a combination of molded products, it is relatively easier. If it is new product development, it is necessary to choose radiation-resistant materials as much as possible; starting from scratch is not easy.

This has to be done by a third-party agency; the requirements for nuclear power in this area are extremely high – even a single transmitter for nuclear-grade instruments can cost tens of thousands of dollars. . . It’s not that simple; I’m not entirely sure either

The main issue is that the electronic components inside are difficult to work with; nowadays it’s understood that components should be separated as much as possible to keep them away from radiation!

Right. In electronic components, non-metallic materials such as organic resins have their molecular bonds break down rapidly under gamma or neutron irradiation, resulting in a rapid deterioration of the material’s properties ； At the same time, relatively thin metals such as reeds can also suffer from irradiation degradation due to neutron irradiation, resulting in changes in their metallic properties. Nuclear-grade instruments used in nuclear power or nuclear chemical industries have high development costs, yet limited market demand; as a result, a significant portion of those development costs is reflected in their selling price. Despite the use of various new materials, there is still a significant difference in radiation resistance among devices of the same function from different brands. For example, some devices claim to be radiation-resistant, but they cannot even withstand the orange zone, let alone operate in the red zone. A split layout is a good way to address similar problems; by moving the electronic components outside the irradiation area, it is possible to **improve the reliability of the system**.

I haven’t had any experience with instruments related to nuclear power yet

The most crucial thing is having a nuclear safety law in place; many instruments related to safety require certification. So even having money isn’t enough – you also need the right equipment and personnel.

Shanghai Guanghua produces even ordinary transmitters poorly, as well as nuclear-grade transmitters. Some nuclear-grade instruments are manufactured through OEM contracts. As the saying goes, as long as there’s money (which in most cases comes from local authorities or energy agencies or something similar), everything can be sorted out.

I did some research on this Guanghua company, which is a state-owned enterprise; I could only laugh. A good background gives an advantage in everything, and it’s applicable to all regions and industries.

There’s nothing I can do; after all, someone else has the certificate! A small solenoid valve in Anshan, Liaoning, can cost tens of thousands of yuan!
