6.6 Inadequate Original Tensioning of Tendons

Description:

Initial tensioning of tendons could lead to excessive stresses in the containment structure.

This is of particular importance as the CR3 containment dome did delaminate upon tendon original tensioning in 1976 (FM 6.6 Exhibit 4) as well as another Florida containment dome that delaminated at Turkey Point upon original tendon tensioning (FM 6.6 Exhibit 5).Excessive original tensioning can damage the concrete by generating localized micro-cracks and/or enhanced creep rates.Also, unbalanced or incorrectly sequenced post-tensioning can lead to high local stresses, micro-cracks and/or delamination.

Data to be collected and Analyzed: 1. Review initial tendon force requirements (FM 6.6 Exhibit 1);2. Review initial tendon tensioning data (FM 6.6 Exhibit 2);3. Review first surveillance lift-off measurements (FM 6.6 Exhibit 3);4. Review original tensioning sequence (FM 6.6 Exhibit 7);Discussion:

The issue of excessive pre-stress by design is included in FM 1.3 as it is a design feature (this is the hoop pre-stress equal to 1.6 times the accident pressure).

The current failure mode deals with the field tensioning in excess of the pre-stress design.2/3/10 P- H , .Page 1 of 3 Daefeate to p=-w t b§t 1 Draft1 The initial tendon tensioning was sufficient to cause delamination early in the life of the containments in the case of the CR3 dome and the Turkey Point dome (FM 6.6 Exhibit 4 and FM 6.6 Exhibit 5). In both cases, issues of radial tensile stresses, tension-compression interactions, and limitations in the concrete tensile strength were indicated as root cause for the events.Samples of the original tendon tensioning sheets are shown in FM 6.6 Exhibit 2. The tensioning sheets contain the hydraulic pressure on the jacks while the tendon force is the number typically referred to. The relationship between the two numbers is linear and well-known. Each jack is calibrated and the linear relationship is slightly different for each one (FM 6.6 Exhibit 8). For the original tensioning jacks used by VSL, the approximate relationship is that 6,800 psi of hydraulic pressure at the jack is equivalent to a tendon force of 1,635 kips.Tendon 12V20 shows a lift-off force of 1785 kips at the first tendon surveillance even though the original stressing record does not indicate any special problem with this tendon (FM 6.6 Exhibit 9). Tendon 12V20 does not go around any penetration.

The excessive force was recorded again at the second surveillance (1740 kips) before being re-locked off at 1630 kips during the third surveillance.

Tendons 45V3 and 56V1 lift-off measurements were also above the 1,635 kips.Besides the overstressing, the sequence of tensioning is important, both in terms of elastic shortening losses for the various tendons, and in terms of asymmetrical loading of the concrete.

The examination of the original detensioning sequence indicates that the CR3 containment was evenly loaded upon tensioning.

The key results here are that there was no indication at the time of the CR3 dome delamination, or since in regular surveillance activities, that the wall had delaminated, and that the CTL condition assessment analysis, using Impulse Response technology, showed there are no delamination in five of the six CR3 containment panels (FM 6.6 Exhibit 6, see Summary page 4 of 96).This indicates that original tendon tensioning by itself did not create the delamination.

Verified Supporting Evidence: a. First surveillance lift-off measurements did detect 3 over-tensioned vertical tendons (FM 6.6 Exhibit 3);2/3/10 PW-Pr8 '12i..d 2009 Page 2 of 3 Draft1 Verified Refuting Evidence: b. Maximum tendon force is 1,635 kips (FM 6.6 Exhibit 1, page 5 of 5). This is as designed and not expected to create excessive tensile radial stresses (see also FM 1.3);c. Original tensioning sheets did not report any over-tensioned tendons;d. First surveillance lift-off measurements did not detect any over-tensioned hoop tendons (FM 6.6 Exhibit 3);e. There was no indication at the time of the CR3 dome delamination, or since in regular surveillance activities, that the wall had delaminated as well;f. The CTL condition assessment analysis, using Impulse Response technology, showed there are no delamination in five of the six CR3 containment panels (FM 6.6 Exhibit 6, see Summary page 4 of 96). This tends to indicate that original tendon tensioning by itself did not create the delamination.

==

Conclusion:==

We have not found evidence that the original tendon tensioning was done so incorrectly as to have been a contributor to the delamination, either alone or in combination with other factors.2/3/10 Draft 1 iUI-~k~ ; 'z~z..t~L2C.&JPage 3 of 3 JFM 6.6 Exhibit 1 1, ,__n~ NUCLEAR OPERATIONS ENGINEERING

Its failure might cause or increase the severity of a loss-of-coolant accident (LOCA).2. Its failure might result in an uncontrolled release of radioactivity.

3. It is vital to safe shutdown and isolation of the reactor.In addition, the Containment Structure provides shielding from the fission products which could be airborne in the building under accident conditions.

The containment is composed of those elements listed in the Table of Contents for this Design Basis Document.The Reactor Building is a concrete structure with a cylindrical wall, a flat foundation mat, and a shallow dome roof. The foundation slab is reinforced with conventional mild-steel reinforcing.

The cylindrical wall is prestressed with a post-tensioning system in the vertical and horizontal (hoop) directions.

The dome roof is prestressed utilizing a three-way post-tensioning system. The inside surface of the reactor building is lined with a carbon steel liner to ensure a high degree of leak tightness during operating and accident conditions.

Nominal liner plate thickness is 3/8 inch for the cylinder and dome and 1/4 inch for the base.The foundation mat is bearing on competent bearing material and is 12-1/2 feet thick with a 2 feet thick concrete slab above the bottom liner plate. The cylindrical portion has an inside diameter of 130 feet, wall thickness of 3 feet 6 inches, and a height of 157 feet from the top of the foundation mat to the spring line. The shallow dome roof has a large radius of 110 feet, a transition radius of 20 feet 6 inches, and a thickness of 3 feet.Tab 1/1, Revision 6 page 5 of 5 CRYSTAL RIVER UNIT 3 Page 15 of 44 Rev. 6 DESIGN BASIS DOCUMENT SYSTEM NAME: SYSTEM CODE: CONTAINMENT

Subject:

Docket No. 50-302 l)car Mr. Volganeau:

Pursuant to I0CF-Ri0.5iS, we wish to follow up our verbal (telephone) notification of 4/19/76 regarding a separation in the concrete of the Crystal River Unit t13 containment structure dome. We have now documented the apparent extent.of this separation.

To recap, the following i.s the sequence of events of the investigation.

On Wednesday, April 14, 1976, while placing cinch anchors in t he dome concrete of the Reactor Building, it was noted that there appeared to be a hollow area about one inch beneath the surface. Investigation on Friday, April. 16, by saw cutting and removing a section of concrete approximately one foot.wide by three feet long, showed that the depth of. the hollow area went deeper as i.t went higher on the dome. By core drill-ing on Saturday and Sunday, April 17 and 18, it was further determined that the separation continued across the dome and went as deep as 15" and separated as much as 1-3/4 inches.By using acoustic methods, the lower perimeter of the separated area was determined to extend all. around the dome in pours I"G"t, "111" and "J"'.Our engineers are now evaluati.jg the present condition of the structure.

Sketches marked I, I, Ill , IV, V, and VI illustrate the apparent extent of the separation as i ndicated by )the limit ed data avai.lable at this time.General Oeflice 3201 hi ty-fourth Steet South 0 PCO Box 1404P2 St PF(!rshWO, F i0ri]_i 33u'3'-i`

REMISON Calculation S-95-0082 1 ATTACHMENT C ORIGINAL TENDON STRESSING SEQUENCES NOTE The original tendon stressing sequences as determined at the time of original tendon installation are still utilized in various calculations and procedures for the tendon surveillance program. Reference I 1 contains tendon stressing sequences and related information which was used as a basis for this calculation effort. As part of this calculation, this original stressing information was tabulated in an Excel spreadsheet to allow for faster sort/select capabilities and easier determination of the stressing sequence for an individual tendon. Information from the Reference 1 Calculation, as related to stressing sequences, was tabulated and included within this Attachment.

The data was input by the sequence number and then verified with the source input. In addition to the basic sort by sequence number to match the input data, a second sort was generated from the same data to represent the sort by tendon number.Note that during the input and tabulation of the stressing sequences for this calculation, some minor errors were discovered in the base data. These items are noted and explained in the attached information, along with any assumptions made in the use of the data.Also note that the original stressing sequences as tabulated and presented herein, as well as the Original Stressing Liftoff data in Enclosure 9 of SP-182, Revision 11, have not been updated to reflect those tendons detensioned and retensioned since the original tensioning effort. (The original stressing liftoff values have been routinely presented within Surveillance Procedure, SP- 182, Enclosure 9.) As more and more tendons become retensioned in the future, there will be a resulting effect on elastic shortening, normalization factors, as well as related calculations which may need to be considered in future efforts.1I e~s RET: Lk a, nEW K~ur NUWW EngIl~eemg 6" RU: LUfa of ftro REW Nud~ew rqFnlneen FM 6.6 Exhibit 7 page 2 of 23 Florida Power Corporation

HYDRAULIC JACK CALIBRATIONS Precision Surveillance has developed a program for calibrating hydraulic jacks utilizing regression analysis (PSC Procedure QA 12.8.G-WV).

This is a process where a straight line is mathematically best fitted to a set of data points (in this case, force verses gauge pressure).

This results in calculating ram area (slope) and constant (y-intercept) for each jack calibration.

Completed calibrations for all of the hydraulic jacks used are contained in Appendix C and are summarized in Table VII.A before and after comparison of the stressing jacks' ram areas revealed that none of the jacks'calibrations varied by more than 0.62% indicating that they were in a properly calibrated status.Note that the force exerted by a jack can be calculated as follows: Force = Area x Pressure + Constant (F) (in 2) (KSI) (K)25 FM 6.6 Exhibit 8 c , C page 2 of 2 C 25TH YEAR SURVEILLANCE OF THE PoSr-TENIONISSYSTEM AT THE CRYSTAL RIVER NUCLEAR PLANT Florida Power UNIT 3 A Progress Energy Company TABLE VII: HYDRAULIC JACK CALIBRATIONS JACK BEFORE SURVEILLANCE FORCE AFTER SURVEILLANCE FORCE MAX VARI ID DATE AREA CONSTANT (Fi) DATE AREA CONSTANT (F0) PRESSURE %(in') (kips) I I (in 2) (kips)8752 4/6/01 331.036 -11.329 1,809,369 1/9/02 331.018 -12.836 1,807,763 5500 0.09 8783 8/1/01 333.733 -9.037 1,893,241.1 1/9/02 335.843 -9.335 1,904,970.1 5700 0.62 8833 8/1/01 334.599 -3.885 1,903,329.3 1/8/02 332.645 -4.175 1,891,901.5 5700 0.60 7711 1/9/02 1.654 0.104 14163 1/17/12 1.642 0.158 14115 8500 0.34 I'.J RAM 7711 USED FOR WIRE TESTING "0O CRYST,',L PRIVER W:;!
