Patent number: 10679760Abstract: A nuclear instrumentation system includes a source range channel, an intermediate range channel, and a power range channel. Each channel includes one detector installed around the pressure vessel. The detectors of the power range channel and the intermediate range channel both include several fission chambers. The detectors of the intermediate range channel and power range channel share several fission chambers. Since some detectors employ fission chambers, the Gamma radiation resistance property, anti-noise property, and anti-electromagnetic interference property are improved. Sharing fission chambers reduces the number of detectors to be installed, thus relieving the installation workload and the positioning of a follow-up detector. Further, the system increases the number of some channels, which increases redundancy and improves system reliability.Type: GrantFiled: November 12, 2015Date of Patent: June 9, 2020Assignees: CHINA NUCLEAR POWER ENGINEERING COMPANY LTD., CHINA GENERAL NUCLEAR POWER CORPORATIONInventors: Tianyou Li, Li Zeng, Rui Zhang, Hao Yang, Xing Wang, Yajie Tian, Ji Shi, Wei Wang, Huaqing Peng, Weihua Chen, Weijun Huang, Hui Jiang

Patent number: 10040898Abstract: It relates to the field of synthetic macromolecular chemistry, and discloses a method for one-step synthesis of thiol-functionalized polyester polyols by organic catalysis. This method uses lactone monomer as reaction raw material, thiol-alcohol as initiator, and diphenyl phosphate as organic catalyst to catalyze and synthesize the thiol-functionalized polyester polyols. The present invention provides a method which is simple, inexpensive, easily controllable and environmentally friendly to prepare thiol-functionalized polyester polyols with the easily available and controllable catalyst. The method can selectively catalyze the ring opening polymerization of lactone to prepare thiol-functionalized polyester polyols using the organic catalyst.Type: GrantFiled: November 30, 2016Date of Patent: August 7, 2018Assignee: NANJING TECH UNIVERSITYInventors: Kai Guo, Yihuan Liu, Ning Zhu, Xin Hu, Zheng Fang, Weiyang Feng, Weijun Huang
