ABSTRACT:
A grading system for a pressurized water reactor steam generator secondary side performance that provides a cumulative assessment of tube bundle deposit inventory and characteristics, i.e., scale density and distribution, hard scale collar formation, thermal performance, loose parts management, and steam generator secondary side chemistry performance. Results are summarized in a cumulative quality point average with individual parameter ratings available so that specific performance improvement may be achieved.
