T1R21 Steam Generator Inspections Inspection Scope:
100% full-length inspection (bobbin probe) 2-Tube Periphery for Loose Parts (combo array probe) TTS to 01S Diagnostic Di ti EExams anddTTube b Pl Plugging i as needed d d Other Actions Taken:
Revised plant heat-up procedures to equalize temperatures to mitigate wear Met with NRC Region I & Site Residents to achieve alignment on inspection scenarios/strategy
- 1. Primary-to-Secondary Leakage No observable primary-to-secondary leakage (PSL) during Cycle 20.
RM-A-5/15 monitor PSLR Continuously.
No observable trends.
- 2. Secondary Side Pressure Tests There were no secondary side pressure tests performed during T1R21.
A drip or bubble test was not required due to the absence of existing primary primary-to-secondary to secondary leakage leakage.
- 3. EPRI Guideline Exceptions TMI-1 has not taken any exceptions or deviations from the EPRI SGMP Guidelines.
- 4. Detailed Scope Evaluation
- 100% full length exam of both OTSGs with bobbin probe
- 2-tube periphery array combo probe exam from TTS to 01S
- All bobbin I codes, PLPs, new DNG /DNT >=
