Development of in situ test procedures for TMI-2 axial power shaping rod-drive mechanisms
General Public Utilities Nuclear Corporation (GPUNC), Babcock and Wilcox (B and W), and EG and G Idaho participated jointly in tests at Diamond Power Specialty Corporation, Lancaster, Ohio, to develop an in-situ dynamic test procedure for application to the TMI-2 Axial Power Shaping Rods (APSRs). An APSR drive mechanism was set up with operating controls and instrumentation. Testing took place on an air stand installation and on an autoclave which simulated conditions of a stator in a water-filled reactor. Dynamic tests established mechanism electrical transient and acoustic signature characteristics associated with mechanism response to energizing and running various modes. Static tests determined characteristics unrelated to actual motion. Analysis of data from the controlled experiments resulted in development of a set of baseline characteristics to be used as a reference for evaluating the condition and response of installed APSRs. A test was devised for use at TMI-2 to verify APSR operability, to drive the APSRs to their lower limits, and to acquire data for potential clues to condition of the reactor core.
