TAILIEUCHUNG - Research on mechanical shim application with compensated prompt current of vanadium detectors

Mechanical shim is an advanced technology for reactor power and axial offset control with control rod assemblies. To address the adverse accuracy impact on the ex-core power range neutron flux measurements-based axial offset control resulting from the variable positions of control rod assemblies, the lead-lag-compensated in-core self-powered vanadium detector signals are utilized. | Research on mechanical shim application with compensated prompt current of vanadium detectors N u c l e a r E n g i n e e r i n g a n d T e c h n o l o g y 4 9 ( 2 0 1 7 ) 1 4 1 e1 4 7 Available online at ScienceDirect Nuclear Engineering and Technology journal homepage: Original Article Research on Mechanical Shim Application with Compensated Prompt g Current of Vanadium Detectors Zhi Xu Suzhou Nuclear Power Research Institute, Xihuan Road 1788, Suzhou, Jiangsu 215004, PR China article info abstract Article history: Mechanical shim is an advanced technology for reactor power and axial offset control with Received 30 March 2016 control rod assemblies.

The prompt g current of self-powered detector is Available online 13 October 2016 ignored normally due to its weakness compared with the delayed b current, although it promptly reflects the flux change of the core. Based on the features of the prompt g current, Keywords: a method for configuration of the lead-lag dynamic compensator is proposed. The simu- Lead Lag lations indicate that the method can improve dynamic response significantly with negli- Mechanical Shim gible adverse effects on the steady response. The robustness of the design implies that the Prompt g Current method is of great value for engineering applications.
