Although not currently included in RG 1. 45, an acoustic emission crack monitoring system capable of detecting crack initiation and growth before a leak occurs was also evaluated. In addition, technology that can monitor or detect other ( noncracking ) degradation modes such as boric acid corrosion or erosion corrosion was studied. These evaluations show that leak detection technology is available that can be used to provide greater detection sensitivity and more accurate determination of leakage locations. Even some of the existing systems have sufficient sensitivity to detect unidentified leakage of 0. 032 kg s ( 0. 5 gpm ) or even less. Experiments and models for RCS leak rate were reviewed to identify correlations between crack size, crack - tip - opening displacement ( CTOD ), and leak rate. Sensitivity studies using SQUIRT ( Seepage Quantification of Upsets In Reactor Tubes ) were carried out to correlate crack parameters such as crack size and CTOD and leak rate for various types of crack configurations in RCS components. Results from validation of the SQUIRT code are presented. For leak rates greater than 0. 02 kg s ( 0. 32 gpm ) most of the deviations between the data and the SQUIRT predictions are bounded by a factor of 2. Leak rates from tighter cracks are predicted less accurately. For leak rates less than 0. 02 kg s ( 0. 32 gpm ), the differences between the data and the SQUIRT predictions are bounded by factors of 10 and - 5. Factors describing the roughness and tortuosity of the crack are part of the input to SQUIRT. For very tight cracks, these parameters are dependent on the crack opening displacement ( COD ), but the relations between these factors and . . . This item ships from La Vergne,TN.<
