| Abstract: |
| In-core neutron infusing rate measurement system is one of the important parts of 300 000 kW nuclear power station. The manual valve, check valve, and motorized valve of the system are nuclear safety class equipments. The composition and function of the in-core neutron infusing rate measurement system was introduced. The type test technical requirements of the manual valve, check valve, and motorized valve were put forward according to ASME QME-1—2002 from the aspects of test item, environmental condition, and checking indicators. Test program of the manual valve, check valve, and motorized valve were established by manufacturer according to the type test technical requirements. The type tests and verification were carried out on prototypes. The results showed that the valves meet the requirements of the test program. |
