Selection of instruments for the nuclear industry, installation, and methods for indicating station numbers
Thread Content
Which expert is familiar with the selection of instruments in the nuclear industry, their installation, and the methods for indicating station numbers? Let’s discuss it
There are no special requirements for selection; in extreme environments, the equipment must be radiation-resistant. The installation method is generally similar to that in the general industry, and in principle, GB50235 and GB50093 can be applied. The device numbering varies depending on the project management approach; generally, it follows the principles established by the general contractor. Aside from the complexity of the KKS coding system and its poor readability, it is usually easy to understand, with little difference from the standards used in the chemical industry. There are mainly the following two types: 1. Two-character codes. The first character indicates the category: L stands for on-site display, M for analog transmitters, S for digital instruments, and so on. The second digit indicates the function: P for pressure, N for level, D for flow rate, G for analysis, T for temperature… For example, 001MP; it consists of multiple letters. The first character indicates the function: P for pressure, N for level, D for flow rate, G for analysis, T for temperature, etc. The subsequent sequential order indicates the category: I for display, C for control, A for alarm… Such as 001PICA
It’s different; the thermometer (probe) is denoted by MT, and the workstation number is quite long.
