Plant: Dresden Unit 2 Components in BWRVIP Scope Core Spray Piping Reactor Internals Inspection History Date or fuspection Summarize the Following fuformation:
Frequency of Method fuspection Results, Repairs, fuspection Used Replacements, Reinspections 1980s to UT, VT-1 IEB 80-13 (1 MIL) VT-1 of piping and D2R14 (lMIL) welds in annulus. fudications observed at one lower elbow to riser weld (3P4c) and two collar to shroud pipe welds (3 and 4P8a) in 1995. All flaw lengths verified with UT. Full structural margins met on all three flawed welds for additional cycle. No repairs performed.
3/1998 UT, GE CSI-2000 fuspected with EVT-1 D2R15 0.0005" supplement for unqualified welds (P8a EVT and P4d). Identified three previously unidentified flaws (1P5, 2P8a and 3P4d) for a total of six flaws. All flaws were analyzed for two additional cycles of operation with no repairs required.
Previously identified flaws were determined to be of the same or less extent than originally sized. 1P5 and 2P8a were not visually verified.
10/2000 EVT-1 Core Spray Piping: P8a and P4d, D2R16 EVT-1 @all four locations. Previous indications have been found on the Core Spray Elbow to Collar on the 260° Downcomer. The results of the 1999 measurements compared with the two previous 1998 indications are as follows.
It appears that the Collar indication has not changed, while the indication on the elbow is larger this year than was seen in 1998. The noted crack growth was bounded by the previous flaw evaluation and the BWRVIP-18 crack growth value.
10/2001 UT, GE CSI-2000 inspected a complete D2R17 EVT-1 Target Set and a sample of P4 welds. No new flaws. Growth within Fracture Mechanics Evaluation predictions.
Performed EVT-1 ofundemonstrated welds.

10/2003 EVT-1, Excessive grinding exam of l-4P4a and b D2Rl8 VT-1 (VT-1). Undemonstrated l-4P8a and P4d(EVT-1). Flaws are unchanged.
11/2005 UT, GE CSI-2000 inspected all demonstrated D2Rl9 EVT-1 welds. Previous flaws re-sized, growth within flaw evaluation and BWRVIP-18 predictions. EVT-1 all undemonstrated welds. No new flaws identified.
EVT-1 25% (2) piping bracket assembly welds. NRI.
11/2007 EVT-1 EVT-lofpiping welds Pl, P2, P3 P8a, D2R20 P8b and 25% of P4a, P4b, P4c and P4d in accordance with BWRVIP-18. Rls for previous indications in 3P4d, 3P8a, 4P8a.

- VT-2 leakage inspections have been and are performed on all RPV Instrumentation Nozzles and Piping Nozzles each refuel outage. An enhanced leakage inspection is performed on all locations to ensure no pressure boundary leakage. Inspections are performed in the annulus area adjacent to the vessel skirt, and are performed under vessel to ensure that any leakage identified is not from welded connections. Flange leakage from CRDM's is recorded, evaluated, and repaired if necessary.
Mirror insulation is opened for SLC safe end inspection and for bottom head inspections but is not removed from other locations unless the leakage source can't be determined.

Plant: Dresden Unit 2 Components in BWRVIP Scope Core Spray Piping Reactor Internals Inspection History Date or fuspection Summarize the Following fuformation:
Frequency of Method fuspection Results, Repairs, fuspection Used Replacements, Reinspections 1980s to UT, VT-1 IEB 80-13 (1 MIL) VT-1 of piping and D2R14 (lMIL) welds in annulus. fudications observed at one lower elbow to riser weld (3P4c) and two collar to shroud pipe welds (3 and 4P8a) in 1995. All flaw lengths verified with UT. Full structural margins met on all three flawed welds for additional cycle. No repairs performed.
3/1998 UT, GE CSI-2000 fuspected with EVT-1 D2R15 0.0005" supplement for unqualified welds (P8a EVT and P4d). Identified three previously unidentified flaws (1P5, 2P8a and 3P4d) for a total of six flaws. All flaws were analyzed for two additional cycles of operation with no repairs required.
Previously identified flaws were determined to be of the same or less extent than originally sized. 1P5 and 2P8a were not visually verified.
10/2000 EVT-1 Core Spray Piping: P8a and P4d, D2R16 EVT-1 @all four locations. Previous indications have been found on the Core Spray Elbow to Collar on the 260° Downcomer. The results of the 1999 measurements compared with the two previous 1998 indications are as follows.
It appears that the Collar indication has not changed, while the indication on the elbow is larger this year than was seen in 1998. The noted crack growth was bounded by the previous flaw evaluation and the BWRVIP-18 crack growth value.
10/2001 UT, GE CSI-2000 inspected a complete D2R17 EVT-1 Target Set and a sample of P4 welds. No new flaws. Growth within Fracture Mechanics Evaluation predictions.
Performed EVT-1 ofundemonstrated welds.

10/2003 EVT-1, Excessive grinding exam of l-4P4a and b D2Rl8 VT-1 (VT-1). Undemonstrated l-4P8a and P4d(EVT-1). Flaws are unchanged.
11/2005 UT, GE CSI-2000 inspected all demonstrated D2Rl9 EVT-1 welds. Previous flaws re-sized, growth within flaw evaluation and BWRVIP-18 predictions. EVT-1 all undemonstrated welds. No new flaws identified.

- VT-2 leakage inspections have been and are performed on all RPV Instrumentation Nozzles and Piping Nozzles each refuel outage. An enhanced leakage inspection is performed on all locations to ensure no pressure boundary leakage. Inspections are performed in the annulus area adjacent to the vessel skirt, and are performed under vessel to ensure that any leakage identified is not from welded connections. Flange leakage from CRDM's is recorded, evaluated, and repaired if necessary.
Mirror insulation is opened for SLC safe end inspection and for bottom head inspections but is not removed from other locations unless the leakage source can't be determined.
