1 : lm 0 INTRODUCTION The tendon s urveillance program is a systematic means of assessing the continued quality of the post-tensioning system for the con-tainment structure. It provides a measure of confidence in the condition and functional capability of the system, and an opportu-nity for timely corrective actions should adverse -conditions, such as progressive corrosion, be detected.

The fifth-year tendon surveillance for the Turkey Point Nuclear Power Plant, Unit 4 Containment Structure, consisted of the physical inspection of nine tendons as described in the FSAR Technical Specification, Section 4 '.6 ~ These tendons were: 62H38, 42H80, 64H7O> 12V29, 34V29,.56V29, 1D28, 2D3, and 3D28.

SUMMARY

AND CONCLUSIONS

2. 2 ~Summa This report covers the fifth-year tendon surveillance for the post-tensioning system of the Unit 4 containment structure at the Turkey Point Nuclear Power Plant. The surveillance was started in October 1977 and completed in November 1977 lift-off forces in all surveillance tendons were within the

'he range of the predicted design values, taking into account the losses of prestress due to wire relaxation, concrete creep and shrinkage, and the initial elastic structural deformation.

The load-bearing components of the end anchorage assemblies were found to be in excellent state with no adverse conditions such as progressive corrosion and cracking.

In the mechanical testing of the specimens obtained from the removed tendon wires, no change was detected in the physical properties regarding the yield stress, ultimate strength, and percentage of elongation of the wires since the initial accept-ance tests. The minimum ultimate strength requirement was met by all the specimens, No presence of water or abnormal discoloration was observed in the tendon sheath fillers. Laboratory analysis of the filler samples, obtained from each surveillance tendon, showed that the contents of water, chlorides, nitrates, and sulfides were well within the acceptable limits, 2 ' Conclusions Based on the inspection and tests described herein, it is concluded that the post-tensioning system in the Unit 4 Containment Structure at Turkey Point Nuclear Power Plant is performing within the limits set by design criteria and specifications,

3. 0 GENEEIIL The fifth-year tendon surveillance of the Turkey Point Nuclear Power Plant, Unit 4 Containment Structure Post-Tensioning System, began in October 1977, approximately 2-1/2 years after the completion of the third year surveillance in February 1975. The fifth-year tendon sur-veillance consisted of the following:

1. Visual and laboratory examination of sheath filler.

2~ Inspecting anchorage assemblies for deleterious conditions, such as corrosion, cracking, missing wires, and split or off-size button>>heads.

3. Measuring shim dimensions to determine tendon lift-off elongations.

4. Measuring tendon lift-offforces.

5. Measuring tendon elongations at 80 percent of the minimum ultimate strength of the wires.

6. Detensioning tendons and checking wire continuity by pulling each wire from one end and observing its movement at the opposite end.

7. Removing one wire from three preselected tendons for inspection and testing.

8. Retensioning tendons to lift-offforces obtained in Item 4 above, and measuring the corresponding elongations.

9. Visual inspection of removed tendon wires for corrosion, pitting, and other deleterious conditions.

10. Testing of samples obtained from removed tendon wires for yield strength, ultimate strength; and percentage of elongation at ultimate strength.

of surveillance data and test results to assess

'valuation the general condition of the post-tensioning system, con-sidering the time-dependent factors such as prestress losses and corrosion.

The work was performed in accordance with the "Tendon Surveillance procedure for Containment Structure Post-Tensioning System," dated July 22, 1977 and included in the report as Appendix A.

The locations and identifications of the dome, vertical, and horizontal surveillance tendons are shown in Figure 3-1.

4.0 SHEATH FILLER AND END ANCHORAGE ASSEESLIES The results of the field inspection and laboratory analysis of the sheath filler, and the visual examination of the end anchorage assem-blies, are summarized in Table 4.1.

4.1 Sheath Filler Two samples of filler were removed from each of the surveillance tendons and visually examined. All of the samples taken were dark brown in appearance, indicating the lack of water or impurities that may cause discoloration.

4 ' End Anchora e Assemblies The end anchorage assemblies of the surveillance tendons were examined and found to be in satisfactory condition. The tendon 1D28 stressing washer, located at buttress 4, received a 120o, 9" long, 3/8" wide, 1/4" deep, tapered scrape along the side of its interior face circumference when it accidentally mated against the left side of the bearing plate during detensioning operations. The stressing washer was shown to be structurally sound when the tendon was stressed to the full effective force with no observable adverse effect, The lift-off forces were well within the acceptable limitsi The end anchorage inspection data are included in the report as Appendix C, 5,0 DETENSIONING 'AND WIRE INSPECTION Data obtained during detensioning and wire inspection are shown Table 5 in 5~1 Tendon Lift<<Off Forces The lift-off forces obtained from the tendons during detensioning Mdicated that prestress losses had not exceeded the predicted design values.

The long term (40<<year duration) predictions of the normalized wire lift-off forces in the surveillance tendons are shown graphically in Figures 5 ' through'5.3 ~ These predictions had taken into account the prestress losses due to wire relaxation, and concrete creep and shrinkage. These curves provide only an estimated trend in the prestress losses, and are used as a means for comparison with the trend of the actual average prestress losses, The minimum effective design prestress is the required average force per wire at the end of 40 years; including the effects of wire relaxation, and concrete creep and shrinkage.

Calculations for the predicted prestress losses are as follows:

Initial wire force (Fi) based on a wire stress of 0 '0f:

Fi ~ 0,70f x As

~ 0 '0 x 240 x 0.049

a 1

~ 8 '5 kips/wire where f= ultimate strength of wire As ~ Area of wire Wire force at 40 years (F40) due to wire relaxation, and concrete creep and shrinkage:

The prestress loss at the end of 40 years due to wire relaxation, and concrete creep and shrinkage, is estimated to be 34.7 ksi (see FSAR Section 5.1.4.4) ~ This value is applicable to all dome, horizontal, and vertical tendons.

F - 34.7 x As

~ 34,7 x 0+049

~ 1.70 kips/wire Where F 1 = Prestress loss 8 40 years P

The minimum effective design prestress is the predicted average wire force after 40 years.

F40 Fi - Fpl

= 8.25 - li70

~ 6 '5 kips/wire In order to compare the actual average prestress losses with predicted values, it was necessary that the wire lift-offforces, from the surveillance data, be normalized to account for the initial structural deformations (which is a function of the post-tensioning sequences), the deviations of initial lift-off forces from the specified value of 0.70f, and the changes in lift-off forces resulting from tendon surveillance operations, such as reshiming and wire removal. These normalized wire lift-off forces were then superimposed on the appropriate

,curves shown on Figures 5.1 thru 5.3, providing a corn<<

parison between the predicted values and the actual forces at the time of tendon surveillance.

For future convenience, the normalizing factors and the normalized lift-off force for each surveillance tendon for the fifth-year tendon surveill'ance are listed in Table 5 '

for calculating the normalizing factors are given

'ormulas in Appendix B

I L

5 ' Wire Ins ection The results of inspection of each tendon wire removed for inspec-tion are shown in Appendix D, No physical imperfections were observed on the wires removed from all tendons.

5 ' Discontinuous 'Wires No discontinuous wires were found during this tendon surveillance.

6,0 RETENSIONING AND SHEATH FILLER'INSTALLATION The data obtained during retensioning are shown in Table 6,1.

The tendons were retensioned to approximately the same stress level indicated by the lift-off forces obtained during deten-sioning, with allowance made for the tendons where< a wire was removed for physical examination and testing.

The retensioning data will be used as input for the next scheduled tendon surveillance.

6 ' Sheath Filler Installation The volume of grease removed from the tendon prior to detensioning, and the volume replaced after retensioning, are indicated in Table 6.1 ~

7~0 WIRE TESTING AND ANALYSIS OF SHEATH FILLER 7 '.1 Specimen Selection and Preparation The locations of the specimens selected from each tendon wire for tensile testing are shown in Appendix D. In general, specimens were obtained from each end and the middle of each tendon wire removed. The specimens were cut to a length of approximately 126 inches.

After the specimens were cut from the pulled wires, they were tagged with the following information:

1. Tendon identification number,

2. Location of the specimen; i,e,, middle or end section.

3, Containment unit number and the year of surveillance (1977) ~

1 1

These tags remained with the specimens through completion of the testing.

The remaining portions of the wires, after the specimens had been obtained, were also tagged and retained at the plant site until testing indicated that the tensile strength and elongation of all specimens were in compli-ance with the specification, 7 ',2 Test Procedure Except for the gage length, the test procedure used was the same as that specified in ASTM Specification A421-65, "Standard Specification for Uncoated Stress-Relieved Wire for Prestressed Concrete." A gage length of one hundred inch '(+1.0) was used instead of the ten>>inch gage length as specified.

The 100-inch-gage-length specimen may indicate a lower ultimate strength and lesser ductility (elongation) than a ten-inch-gage-length specimen. Since failure will occur't the weakest point in the wire, the ultimate strength obtained is equivalent to the lowest value that would be obtained from ten 10-inch specimens, Elongation at failure will also tend to be less due to the distribution of the elongation at the neck-down area over a length of wire ten times that of the nominal ten-inch specimen.

7,1,3 Test Equipment The apparatus used for the tensile testing of the specimens was the Tinius Olsen Super "L" Testing machine with a 1,200,000 lbs capacity, of the Pittsburgh Testing Laboratory, Pittsburgh, Pennsylvania, For machine calibration report, see Appendix I.

7 ',4 Test Results The results of tensile testing on the one hundred-inch-gage-length wire specimens are shown in Appendix G and Table 7,1, 7.1.4.1 Yieeld Strength The yield strength of all wire specimens tested exceeded the specified minimum yield strength of 192 ksi at one percent elongation.

7,1.4 ' Ultimate Strength The ultimate strength of all wire specimens tested exceeded the specified minimum ultimate strength of 240 ksi as specified by AS&i A421-65.

F 1;4,3 Elongation Since 100>>inch-gage-length specimens were used in the tensile testing, a lesser percentage of elongation may be expected than from the testing of 10-inch>>gage-length specimens of identical wire, as discussed in Paragraph 7 '.2 ~ Previous test data < ) indicated that a wire which showed a 4 percent elongation at ultimate strength in a 10-inch-gage-length testing could be expected to exhibit a somewhat lower (no less than 3 percent) elongation at ultimate strength in a 100-inch-gage-length testing.

The percentage of elongation of all wire specimens tested met this requirement, 7.1.4 ' Fracture Characteristics The fracture of all wire specimens was of the cusp-cone shape.

7 ' Anal sis of Sheath'Filler 7~2~1 Specimen Preparation A quart-size sample of the sheath filler was obtained from each end of all surveillance tendons prior to de-tensioning. Each metal container containing the grease sample was marked with the tendon identification number, One sample from each surveillance tendon was shipped to an independent laboratory for analysis of water content.

and water soluble impurities, and the remaining samples were retained at the jobsite.

7 ' ' Test Procedures Test procedures for water content and chlorides, nitrates, and sulfides concentrations are given in Appendix F.

7.2 ' Test Results The results of laboratory analysis of the sheath filler are shown in Appendix'H, These data indicated that the contents of chlorides, nitrates, and sulfides in the grease were well within the acceptance limits, and that the amount of water present was negligible.

5 3,3 Detensioning Tendons 5+3,3,1 Determine the number of effective wi.res for each tendon fran the previous surveillance.

5 3 3.2 Calculate and record the jacking forces required to obtain the specified 80 percent minimum ulei~te strength (0.8f's) per wire. These forces are ob-tained by multiplying the number of effective wires by 9.43 kips ~ Enter these values into the jack calibration chart to obtain the gage readings equivalent to the forces. Note that the applied jacking force for each tendon shall not exceed the value thus determined.

5,3 3.3 Attach the jack to the bearing plate. Note that if the initial stressing was done from both e"ds of a tendon, the surveillance shall be perfo ~d in the same manner.

5,3 3.4 install the pressure gages to the jack and p~,

and record their identification numbers. iheck the gages for zero pressure reading.

5 3.3.5 Measure the depth of the existing shims.

5,3 3.6 Determine the lift-off force by tensioning the tendon until all shims are loosened. Li t-off is achieved when the sound produced by tapping on shims with a small. hammer changes to indicate release from compression; also, all accessible shims can be moved by tapping with a sra11 hammer Repeat the operation until three measurements of the lift-off forces show a variation of + 50 psig, or less..

Se3o3+7'.3 Depressurize the jack until the gages read zero.

3 8 Pressurize the jack to a force so that the aver-age wire stress is equal to 80 percent of the minimum ultimate strength of the wires, as determined in paragraph 5.3 ',2.

I Revision 1

1. 0 GENERAL In order to provide a common base for comparison, tendon lift-off forces must be normalized to account for elastic stress loss during initial installation (a function of the post-tensioning sequence), of the lift-off fqrce deviation from the base value, and the number effective tendon wires or strands. The base value for evaluating the normalized tendon force is assumed to be the force which produces an average tendon wire or strand stress of 0.7fpu. In cases where the same tendon is subjected to two or more surveillances, the base value for the ith surveillance is the normalized force for the i-1 surveillance.

The normalized force is equal to the measured lift-off forces multi-plied by the normalizing factors.
