Dear Mr. Ei'senhut:

9 Re: Turkey Point Unit 3 Docket No. 50-250 Steam Generator Ins ections The results of the Turkey Point Unit 3 steam generator inspections conducted during the current outage are attached. The inspections which were performed in accordance with Turkey Point Unit 3 operating license DPR-31 showed no new phenomena and'erified that the general pattern of denting in Unit 3 is within predictable limits and consistent with previous inspections of the Turkey Point Units.

The general criteria applied for steam generator inspections and preventive plugging are the same as .previously applied to Turkey Point Units 3 and 4.

This approach provides reasonable assurance of steam generator tube integrity such that safe operation of the unit during normal full power operation and during hypothetical accident conditions is assured for an operating period in excess of six equivalent full power months. Therefore, the implementation of this program with the resulting preventive plugging, enables continued safe full power operation of Turkey Point Unit 3.

Total steam generator tube plugging at the conclusion of the current outage will be approximately 21.0$ . This is conservatively bounded by the 251, tube plugging ECCS analysis.

The results of this inspection and the preventive tube plugging program have been reviewed by the Turkey Point Plant Nuclear Safety Committee and the Florida Power 5 Light Company Nuclear Review Board. They have concluded that based on the inspection results, the implemented plugging pattern, and previously submitted analyses, that the return of Turkey Point Unit 3 to full power operation for at least six equivalent months does not involve an unreviewed safety question.

In accordance with condition E.5 of operating license DPR-31, Florida Power 8 Light Company requests permission to return Unit 3 to power operation for a period of six equivalent full power months.

TURKEY POINT 3 STEAM GENERATOR INSPECTION PROGRAM March, 1981 I. INTRODUCTION An extensive inspection program for the Turkey Point Unit 3 steam generators was conducted in March, 1981. The following were-performed:

1. Gauging of steam generator hot leg and cold leg tubes - all steam generators.

2. Measurements of visible flow slots in all steam generators.

3. Eddy current inspection of small, radius U-bends: in steam generator C.

4. Regulatory Guide 1.83 eddy current measurements in the hot leg and cold leg tubes of all steam generators.

5. Preventive plugging.

Table 1 is a .summary of the approximate number of steam generator tubes inspected in each category and in each steam generator.

I I. INSPECTION PROGRAMS The tube gauging program in the tubelane area is based on previously defined regions where significant tube deformation has been observed. These regions were formerly determined using finite element analysis techniques which yield tube hoop strain contours as a function of plate deformation. The boundary in the peripheral tubelane areas near the three and nine o'lock wedge locations is modified to take into account the greater extent of deformation in these regions of the plate as determined by previous experience.

Initially, a 12.5% strain boundary was used in the gauging program when little plant specific data was available. After two initial inspections and four periodic subsequent inspections of the Turkey Point Plants, review of specific information indicated the conservatism of the 12.5$ boundary. Consequently, a 15%%d boundary was adopted .and used in the gauging program during the April, 1979 inspection at Turkey Point 84. With the addition of the information gained from that inspection (then totaling five reinspections), it became apparent that the 15K boundary was also overly conservative and the 17.5% boundary would be more appropriate for the next inspection (May, 1980). That is, the majority of the tubes inspected in April, 1979 did not restrict the .650 probe. In addition, all tubes restricting the .610 inch or .540 inch probe in the tubelane area were within the inspection boundary. This is significant since the .610 inch and .540 inch restricted tubes form the basis for the plugging patterns in the tubelane region. Accordingly, the 17.5$ boundary was used as the basis for the May, 1980 inspection. Since full'closure of the flowslots was observed in Turkey Point 4 steam generators during the May, 1977 inspection, Turkey Point 4 was regarded in May, 1980 as beyond full closure by approximately 25.5 Effective Full Power Months (EFPM's). Since the 17.5X contour at 24 months appears to involve much of the hot leg tube bundle, the program was adjusted to reflect prior experience.

g ~

iS

As a result of the May, 1980 inspection at Turkey Point 84, it became ap-parent that the calculated 17.5X strain contour overpredicted the plant inspection data and that a finite element model no longer gave reasonable expectations as to the position of a strain boundary which might be linked to the locations of the most extensively restricted tubes.

The next inspections were performed at Turkey Point 83 in October, 1980 and Turkey Point 84 in November, 1980. As a result of the prior experience at both Turkey Point Units described above, the gauging inspection boundaries for these inspections were also adjusted to reflect prior experience.

Additional inspection programs were defined for the periphery, wedge, and patch plate regions. These programs were based on previous tube leakage histories at Turkey Point and Surry Plant sites, as well as previous gauging. results at the Surry and Turkey Point sites as deemed appropriate.

Inspections of all three steam generator cold legs were also performed.

The gauging inspection boundary for the present inspection (March, 1981) at Turkey Point //3 has also been adjusted to reflect prior experience at Turkey Point and other plants, in accordance with the discussion in the pre-ceding paragraphs.

The typical gauging inspection boundaries for the October, 1980 inspection (Fig. and 2) are included for reference. The gauging inspection boundaries 1

for the March, 1981 inspection are indicated in Figures 3 to 8 inclusive, for each leg of each steam generator.

The following conservatisms were utilized in determining the Turkey Point 83 inspection boundary for this inspection:

l. If a restricted tube was found close to the inspection boundary, the inspection was expanded in that area.

0 r ~

2. In addition to the specific gauging inspection program,, it should be noted that tubes in the central portion of the tube bundles from Row 12 upward were tested with 700-mil diameter probes; such probing should provide early indication of any new deformation which might exist away from the, regions usually regarded as active, i.e. the tubelane, patch

'plate, wedges, and periphery.

3. Restricted tubes, discovered in previous inspections, including those that were not adjacent to the areas of predominant activity, were in-corporated into the gauging program laid out generally for the three steam generators.

B. Flow Slot, Measurements Photographs were taken in each steam generator through the secondary hand-holes. These photographs were then utilized to measure the openings in the visible flow slots. Results are discussed in Section III. Flow slot measurements provide a gross measure of the progression of. denting, as re-flected in the rate of flow slot hourglassing.

'I C. Other Denting Related Inspections The U-bends of unplugged tubes in rows 3 thru 5 in steam generator C were examined with 100 kHz to confirm the integrity of the small radius U-bends in low number rows, as shown in Figure 9.

In the January, 1979 inspection, annulus measurements were taken in steam generator B. These measurements provide a qualitative indicator of the upper plate expansion trends in the most affected steam generator. That had been the second measurement of this type for steam generator B. No obvious trends had been noted in this unit or in three such measurements in Turkey Point Unit 0'4.

Therefore, this measurement was not made'at the October, 1980 or March, 1981 inspection and is not planned for future inspections.

D. Regulator Guide l.'83 R.G. 1.83 Ins ection, The types and extent of inspections required in this area are specified in R.G. 1.83. The original inspection plans are included (Figs. 10-15 inclusive).

In addi'tion to a systematic sampling of tubes, all tubes with previous indications, regardless of size., were reinspected, as shown in Figs. 10 to 15.

During the inspections, no expansion of the program (per Regs Guide 1.83) was required in any of the steam generators. Results of the inspection are discussed later in this report.

III. INSPECTION RESULTS A. Gau in Pro rams Results of the gauging inspections are indicated in Figures 16, 17, 18, and 19 are summarized in Table. 2. (Since no tube restrictions were reported in the cold legs of steam generators A and 'B, figures are not included for these legs.)

Summary comments resulting from the review of these,and other data are as fol 1 ows:

Tubes in the tubelane region that restrict the '0.650 inch probe lie adjacent to the areas in which such restrictions occurred in prior examinations.

2. There were no. tubes restricting a 0.540 inch probe in the tubelane regions of the cold legs in any of the three SG's.

3. Tube restrictions were noted, in the wedge areas and the patch plates o'f all three steam generators", these data appear consistent with pre-vious experience.

4. Only limited col'd leg activity, i.e. restrictions to the 0.610 inch probe, was observed: No tubes in SG A,. 2 in SG B, and no tubes in SG C.

The level of cold leg activity remains quite low,'ompared to the hot leg experience.

5. No leaking tubes were observed during the previous operating period.

6. Only a single restriction to the smallest probe used. (0.540 mils) was observed in this inspection after approximately 3.5. EFPM of operation, compared with 13 such restrictions observed in October, 1980 after approximately 8.5 EFPM of operation.

B. Flow Slot Measurements The results of, the flow slot measurements are provided by Figure 23.

C. Other Dentin Related Ins ections The U-bends of unplugged tubes in rows 3 thru 5 in steam generator C were examined at 100 kHz. No indications were. noted in these small radius U-bends.

0. Re ulator Guide 1.83 Ins ection Results and Evaluation The results of'he Regulatory Guide 1.83 inspection are summarized in Table 3. As a result of this inspection, no tubes were pl'ugged for indications equal to or greater than 40K wall penetration.

4 D. NON-DENTING RELATED'NSPECTION During the course of the steam generator inspection program, 1 piece of foreign material was found and retrieved from steam generator 3C (.see attached LER update). It was concluded that this piece of material was of the same origin as the debris previously discovered and reported duri'ng December 1979.

The occurrence has been evaluated and conservatively resolved.

>40 0 0 0 0 Preliminary evaluation of the results suggests probable thinning in the region -of the sludge pile in the cold leg occurring at a rate which has not increased substantially since the October, 1980 inspection.

A comparison of eddy current indications equal to or greater than 20K observed at this inspection was made with similar observations made at the last inspection (October, 1980). The results of this comparison for. the cold leg data are shown in Table. 4. Hot leg comparisons are not tabulated since only a single comparison at most, could be made for each steam generator.. This difference is reflected in the smaller number of indications observed in the hot legs as compared wi.th-the cold legs.

t IV Plu in Criteria Although experience has shown that advance of the predicted strain contours from the finite element model no longer is an appropriate basis for tube plugging, the plugging criteria which were developed using the model have generally been retained, since their application has been ef-fective in reducing the frequency of tube leakage events resulting from denting. As in the .October, 1980 inspection of Turkey Point 3, and the May, 1980 inspection at Turkey Point 4, a program which incorporates all previously observed activity with several rows margin beyond is con-sidered appropriate; again a sampling of central area tubes provided by the Regulatory Guide 1.83 inspection permits detection of new areas of ac-tivity should any occur. The criteria. established for plugging tubes in the region of the patch-plate differ from those used for other reg'ions of the bundle. All leaks in the patch-plate region have occurred at the perimeter of the plate or near to the patch-plate boundary, where plug welds connect the patch-plate to'he main body of the tube support plate. All observed data indicate that the behavior in the patch plate is local in nature and is not consistent with the general strained state of the plate, nor can the behavior be represented by the finite element model. Due to these factors, the regions of. the patch-plate are inspected and a specific set of plugging criteria applied. Because tube leakage in this region have not always re-stricted 0.540 inch probes, leaking tubes and tubes that restrict the 0.540 inch probe should be treated alike, and the surrounding tubes about both should be plugged and tubes on either side of the patch-plate boundary (plate perimeter on'ne side, the plug welds on the other three sides) that restrict the 0.650 inch probe should be plugged.

~ ~

~ ~

Due to the local plate cracking that is believed to occur at the periphery and near wedge locations, tube leaks,.may occur here at lower levels of tube restriction than in the.,tubelane." Thus, the. wedge areas should have their own inspecti'on program and plugging criteria.- The plugging criteria at hot leg wedge locations calls for treating leaking tubes and tubes that re-strict. the 0.540 inch probe in a similar manner. In'ddition, 'tubes that restrict the 0.610 inch probe and peripheral tubes that 'restrict the 0.650 inch probe should be plugged. ,Cold. leg pluggin'g will be based on the degree of activity noted and rates of progression observed from= gauging.

The, plugging criteria which support at least ten months of operation are:

l. All tubes which do not pass the 0.540 inch probe will be plugged.

Only one such tube,(steam generator B; R 15-CIO) was observed in this inspection.

2. Additionally., for in excess of ten (10).-months, operation, two (2) tubes beyond (i.e., higher row n'umbers) any tube in columns 1-92 in the tubelane region which did not pass the 0.540 inch probe will be plugged. (Calcu-lation of the progression of the 17-1/2X strain contour, as determined from finite element plots through 24 EFPM after closure, results in predicted advancement of this contour by 1.9 tube rows for a 10 month operating period. Given the, conservatism of this approach, plugging two additional tubes beyortd observed 540 mil restri'ctions provides adequate:

margin. This criterion was not applicable in this inspection.)

3. All tubes which do not pass the 0.610 inch probe will be plugged.

4. The, tubes in any column for which plugging under criteria (1), (2),

or (3) above- is'mplemented in the tubelane region will also be plugged in the lower row numbered tubes back to the tubelane if not already plugged.

5. As a conservative measure, tubes completely surrounding any known 'leaking tubes including the diagonally next tube will be plugged if not already,"

covered by the foregoing criteria.

~ ~

6. In any -given column which is surrounded by .columns containing tubes with signi,ficant tube restrictions or ppior plugging, (thereby creating a "plugging valley" in the pattern) engineering judgement will be used to fi.ll the bottom of the, valley; In the. peripheral tubel'ane areas near the three and nine o'lock wedges, tubes surrounded by- previously plugged tubes or tubes exhibiting high deformation activity will be plugged based on engineering judgement. Particular attention was paid to 650 mil re-stricted tubes relative to the ten month operating .period.=

7. Additional- preventive plugging will be implemented at the hot leg wedge locations. This plugging wil,l include -all tubes that:

a. Restrict the 0.540 inch probe.

b. 'Restrict the. 0.610 inch probe.

c. Restrict the 0.650. inch probe. at the periphery,.

d. Surround leaking .tubes and tubes that restrict the 0.540 inch probe, including the diagonally next tube.

8. Application of the criteria specified in 7 above, will be made on the basis of engineering judgement for cold leg wedge locations.

9. Additional preventive plugging will .be implemented in the patch plate region.

This plugging will include all tubes that:

a. Restrict the 0.540 inch probe.

b. Restrict the 0.610 inch probe.

c. Surround leaking tubes and tubes that restrict: the 0.540 inch probe including the"diagonally next tube.

d. Lie on either sides of the patchplate boundary (plate perimeter on one side, the plug welds on the other three) and restrict the 0.650 inch probe.

The ten month operating period was also evaluated relative to a postulated main steam line break accident (MSLB). In doing this, it was conservatively assumed

I 4 ~

~ ~

that each unplugged tube in the two rows beyond the present tubelane plugging boundary in the most advanced SG(B) would leak at a rate of 0.05 gpm/tube during a postulated main steam line break. Since there are 92 tubes in a row, the total number of unplugged tubes in the tubelane region lying adjacent to the current plugging boundary at the end of the next six months is less than:

2 x 92 tubes per row = 184 tubes. The total resulting leakage from these tubes would be less than:

184 tubes x 0.05 GPM 9 2 GPM tube This added to the 0.3 GPM leakage assumed to be present at the start of a postu-lated start of a MSLB (which would increase to approximately 0.7 GPM due to MSLB differential pressures) yield a total leakage less than 10 GPM, which has been determined in previous submittals to be an acceptable level of leakage during a pos'tulated MSLB.

B. Re ulator Guide 1.83 The criteria, for plugging tubes in this area are established in the Technical Specifications.

C. Preventive Plu in Accom 1'ished The preventive plugging programs that were implemented to justify at least 10 months operation are indicated in Figures 20, 21 and 22. Table 5 summar-izes the plugging performed at this outage. The coordinates of the plugged tubes are listed for each steam generator in Tables 6, 7 and 8 respectively.

As noted in Table 5 and 8, two tubes were plugged as a conservative measure in steam generator C. These tubes, R16-C41 and R28-C39, were reported as having eddy current indications of 435 and 44K respectively in the November 1974 inspection. These tubes were not plugged at that time since the plugging criterion was then in excess of the reported indications. In addition, no indications were observed in subsequent inspections for tube R16-C41, and an indication of(205 was reported for tube R28-C39 in the October 1975 inspection.

However, as discussed above in Section II 0, Ins ection Pro rams, Re ulator Guide 1.83, all tubes with any previous indications, including these two tubes, were reinspected in March, 1981.

~ ~

In this latest inspection, distorted. tubesheet (DTS), signals were observed for these two tubes. To preclude any possibility that sizeable indications may have been masked by the DTS signal, since indications in excess of 40K wall penetration. had 'been reported previously,, both tubes. were plugged as a conservative measure. These were the only two tubes for which the combination of the above conditions was observed.

/

During refueling shutdown while conducting steam generator inpsections, foreign material was observed on the "as found" 3B steam generator tubesheet photographs.

Subsequent inspection by both licensee and NSSS vendor personnel resulted in discovery and retrieval of the following:

3B S/G Hot Leg 7 pieces of sheet metal type (approx. 16 gauge),

ferromagnetic material

- 1 apparent piece of tube plug skirt (ring), non-ferromagnetic total weight of the above 8 pieces; 243 grams 1 apparent piece of tube plug skirt. non-ferromagnetic material, was removed from R-8, C-12. (The material was retrieved from a point approx. 2 inches up from the primary face of the tubesheet.)

- total weight of the above piece:

4 ' grams 3C S/G Hot Leg 4 pieces of sheet metal type (approx. 16 gauge),

ferromagnetic material total weight of the above 4 pieces.

116 grams During the March 1981 refueling shutdown, while conducting steam generator inspec-tions, foreign material was observed and retrieved from the 3C steam generator.

3C S/G Hot Leg 1 piece of sheet metal type, ferromagnetic material total weight of the above piece:

255 grams Additional Cause Descri tion and Corrective Actions:

Independent laboratory analyses of a sample of the ferromagnetic material con-firmed that the sample is an unalloyed plain carbon steel. Additionally, visual examination of the foreign material supports the conclusion that the objects were from separate sources. i.e., the ferromagnetic objects originated from the same base piece and that the non-ferromagnetic objects were part of a tube plug skirt.

Based on the, fact that unalloyed carbon steel is not used within the reactor coolant system, an examination of equipment in proximity to the reactor vessel/

refueling cavity was conducted. However, the source of the material could not be located, The logical conclusion is that the ferromagnetic material was intro-duced into the reactor coolant system during a previous refueling shutdown, steam generator inspection outage, or during construction. The source of the non-ferromagnetic material was confirmed to be a tube plug that expanded improperly during the plugging process.

Visual examination of the foreign material which was discovered during the March 1981 refueling outage supports the conclusion that it originated from the same base piece which was previously discovered. A Metal Impact Monitoring System

"'" JEEPRTABEE OCCURRENCE 250-70-Q "g LICENSEE EVENT REPORT PAGE THREE had been used to monitor startups following both the previous refueling shut-down and the sfeam generator inspection, however, no abnormalities were detected.

As inspection was performed by licensee and'SSS vendor personnel of the upper internals and of a 90o sector of the reactor vessel where pC piping connects to steam generator "C'. No anomalies, i.e., damage or additional foreign material, were noted.

The steam generator inspection program augmented by a visual examination of both the steam .generator primary side and the reactor vessel provides assurance that,all foreign objects were retrieved from the reactor coolant system. However, we currently plan to employ a Hetal Empact l1onitoring System to monitor startup.

Current inspection, surveillance, and quality control programs/procedures should prevent recurrence of an event of this type.
