Analysis and Improvement of Negative Pressure Problems in DVN System
DVN system is the last link to protect the radiation protection barrier,through its negative pressure control to ensure the integrity and stability of the radiation protection barrier.In practice,it was found that the 8DVN018LP readings were found to be unstable and exceeded the limits in the protocol when performing a test procedure on the negative pressure adjustment of DVN.Based on the principle of negative pressure control of DVN system,the author analyzes the fundamental reason that the 8DVN018LP reading is unstable and exceeds the limit value in the program,and puts forward the reasonable interval to increase the limit value of the program,and then provides the negative pressure monitoring for DVN system Program.
