Radiographic Process for Main Equipment of Nuclear Power Station Primary System in Radiographic Testing

Primary system of nuclear power station is the main examination object of radiographic testing in PSI/ISI. Starting with radiography process in radiographic testing, radiography process and implementation of main equipment as steam generator(SG), reactor pressure vessel(RPV) and pressurizer(PRZ) were introduced quite systematic in primary system of nuclear power station. Radiographic special tools used in each exposure were presented also. Based on the successful experience of pre-service inspection in Lingao No. 3 and 4 nuclear power station, foundation is laid for the PSI/ISI later.
