Design and Implementation of Core Surveillance System for HPR1000 Reactor

Yuanzineng kexue jishu
Difference from the movable neutron detector for CPR1000 reactor can only be used periodically, HPR1000 and other Gen-Ⅲ reactor innovatively use self-powered neutron detector (SPND) to continuously measure the in-core neutron flux.

Unpack the black box of pilot sampling in policy experimentation: A qualitative comparative analysis of China's public hospital reform

Governance, Volume 37, Issue 3, Page 803-824, July 2024.
Abstract Governments increasingly use policy experimentation programs to seek solutions for complex problems. Because randomization and controllability are unrealistic for real‐world policy experiments, how subnational pilots are selected is crucial for generating sound evidence for national replication.
