STARTUP TEST PROCEDURE 35 RECIRCULATION SYSTEM FLOW CALIBRATION 1.
PURPOSE A.
The purpose of this test is to perform a complete calibration of the installed recirculation system flow instrumentation.
2.
ACCEPTANCE CRITERIA A.
Level 2 1.
Jet pump instrumentation shall be adjusted such that the jet pump total flow recorder trill provide a correct core flow indi-cation at rated conditions.
2.
The APRM/RBM flow bias instrumentation shall be adjusted to function properly at rated conditions.
3.
RESULTS Test Condition 3 The core flow instrumentation was recalibrated to correctly indicate core flow as calculated from the individual jet pump dP's.
The APRM/RBM flow signals were verified to be conservatively adjusted.
Since the calculated loop flow variation based on the theoretical flow distribution factor was greater than 3%, additional data will be taken in this test cendition to determine the actual flow distribution factor.
