Research Institution
The designs of many existing Pressurized Water Reactors (PWRs) incorporate a Digital Rod Position Indication (DRPI) system to monitor the positions of the control and shutdown rods within the reactor. These DRPI systems have been in service for over 30 years in nuclear power stations worldwide, and are currently being used as the basis for the rod position indication systems in new designs. In recent years, however, aging and obsolescence issues have led to an increase in problems with the DRPI systems. These problems include analog card failures and coil cable connection issues. These problems, along with plans for plant life extension, have prompted the industry to actively seek viable options to monitor the health and accuracy of these DRPI systems, in order to ensure reliable plant operations for decades to come. As such, this project will establish the feasibility of an advanced DRPI diagnostic system for existing and new PWR reactors. In Phase II, a complete system will be developed for deployment in an existing PWR. Commercial Applications and other Benefits as described by the awardeeThe technology should provide the enhanced diagnostic capabilities needed to monitor DRPI system components in nuclear power plants.
