The inspections performed during the forced outage in March 1992 (2F92-1), were not Technical Specification required inservice inspections.

In letter dated May 12, .992 (2CAN059202), Entergy Operations provided the initial tube inspection results and stated that the complete results of the tube inspections performed during 2F92-1 would be submitted to the Staff. Attached is the Steam Generator Tubing Inservice Inspection Report for 2F92-1.

STEAM GENERATOR TUBING INSERVICE INSPECTION REPORT l MARCH.1992 FORCED OUTAGE (2F92-1)

EXAMINATION

SUMMARY

On March 9, 1992. Arkansas Nuclear One, Unit 2 (ANo-2) was shut down due to a 0.25 GPM leak in the "A" Steam Generator (SG). The leaking tube was found to have a circumferential crack in the expansion transition region at the top of the tubesheet. .

After stabilizing and plugging the leaking tube, AWO-2 examined 100% of the "A" and "B" SC.hotleg inservice tubes at i 2" of the tubesheet secondary side interface.- Due to the number of indications present in the "A" SG hotleg tubing, en-examination was performed in the "A" SG coldleg inservice tubing. _Tnis examination consisted of 20% of the SG tubing located in the center of the sludge pile " kidney" region (- 1000 tubes) at + 2" of the tubesheet secondary side intwrface.

The "A" rnd "B" SG tubing examination was performed utilizing the Motorized Rotating Pancake Coil (MRPC) probe. All tubes found with indications were inspected full length with a bobbin probe. A portion of the tubes with indications were tested using a rotating ultrasonic technique.

The previous inservice inspection was conducted in March 1991 during the l eighth refueling outage (2R8). The inservice inspection expanded to 9% ,

of the "A" SG tubes and 100%'of the "B" SG tubes. Zero (0) tubes were plugged in the "A" SG and seventy-three (73) tubes were plugged in the "B". . The tube indications,- causing the expansion from th3 original planned 3%. was found in the tube support plate regions of the "B" SG and believed to be outside olameter Intergranular Attack (IGA) and Axial +

Stress Corrosion Cracking (SCC).

EXAMINATION RESULTS ,

Circumfe rential crack indications were found in the "A" and "B" SG hotleg tubing. No indications were found in the."A" SG coldleg tubing,_ ,

examination. In the "A" SG, 421 tubes were identified with indications. ~

In the "B" SG, 67 tubes were identified with indications. A11 tubes wi+.h indications were repaired by sleeving or removed from service by plugging. . All tubes plugged due to circumferential indications were also stabilized.

in the "A' SG. 407 tubes were sleeved and 14 tubes were plugged with 8 4 plugged tubes stabilized. Tube segments were removed from 2 of the 14 plugged tubes for laboratory examinations. During the secondary side pressure test. 15 of the 407 installed sleeves leaked. Th 15 sleeved tubes were preventively plugged, bringing the total number of plugged tubes to 29, with 392 sleeved tubes remaining in service.

In the."B" SG, 59 tubes were sleeved and 8 tubes were plugged with 3 plugged tubes stabilized. Tube segments were removed from 3 of the 8 plugged tubes for laboratory examinations. During the secondary side pressure test. 3 of the 59 installed sleeves leaked. The 3 sleeved tubes were prever;tively plugged, bringing the total number of plugged tubes to 11, with 56 sleeved tubes remaining in service.

Tables 3 and 4 list the tubes of which segments were removed from the "A" and "B" SG hotlegs, respectively.

During the sixth refueling outage (2R6), March 1988, Westinghouse installed six mechanical ribbed plugs of Alloy 600 in the "B" SG hotleg '

tubing. In response to NRC Bulletin 89-01, Supplement 2 " Failure of Westinghouce Steam Generator Tube Mechanical Plugs". Entergy Operations committed in letter dsted August 8, 1991 (OCAN089108), to remove and replace or repair these six plugs during the next refueling outage (2R9).

Entergy Operations also stated that if an extended outage (greater than 4 weeks) were to occur before 2R9, these plugs would be replaced or repaired at that time.- The six plugs were repaired by stabilization  ;

utilizing Babcock & Wilcox Nuclear Service (BWNS) Plug-A-Plug (PAP) technique while working the "B" SG during 2F92-1.  ;

I' Table 5 lists the."B" SG hotleg tube plugs that were stabilized utilizing the BWNS PAP-technique.
