F' arsons Date 1/8/96 Project Title . _ RB Horizontal & Dome Tendon Force Page1 of_ Cale: DCO)ofo-oo' R8V 0 J of 21 Page_ , VERIFIER'S COMMENTS The purpose of this TWR is to document the verification performed on DCO3050-001 Rev. O. The verifier has reviewed the calculation methodology,the inputs and the assumptions. A spot check of the math was also performed. This calculation identifies the predicted forces and acceptance criteria for the RB tendons that were selected for the fifth period surveillance, l'revious tendon force predictions were based on subtracting a series of estimated force loss factors from the original lock-off force value. This calculation method replaces these estimated values with graphically derived values. The graphically derived values are extrapolated from previous eurveillance data. This is a more accurate way of deriving the predicted forces since it more accurately defines the unknowns affecting these particular tendons. The calculation inputs include time of original lock-off, original lock-off force, Normalization factors ect.. These values were obtained from previously verified documents and are reasonable and accurate for this application. The primary assumption in this calculation is that if the tendon force vs time is plotted on a semi-log plot,the data points will form a straight line. This assumption is reasonable and is
- shown to be accurate based on previous tendon force data.

DOC 1.0 OBJECTIVES (1) Develop general methodology for predicted liftoff force for the hoop and dome tendons by using the results from previous surveillances, i.e. h traditional approach based on experience.
(2) Develop the predicted liftoff forces for the hoop and dome tendons for the 5th tendon surveillance (15 years after SIT) planned for April 19% using the traditional approach. 1.1 DESIGNINPUTS 1.1.1 De design inputs consist primarily of previous V.C. Summer Station structural calculations. These are clearly referenced where they are referenced in the body of the calculation. 1.1.2 Other documents referred to in the calculations include: (1) SP 228 Surveillance of the Reactor Building Post Tensioning System. (2) Reactor Building Cnntainment Fourth Period Surveillance Tendon Forces Report. May 1990. 1.2 ASSUMPTIONS Assumptions are identified in te calculation where used. There are no assumptions requiring future confirmation. 1.3 COMPUTER USE The software SigmaPlot for Windows by Jandel Corp. is used to plot the graphs of the data points of group average forces from each surveillance to obtain the force vs. time trend for each group of tendons. The data is also plotted manually on semilog graph paper to verify the results using SigmaPlot. 1.4 CALCULATION ne basic sequence of steps to determine predicted liftoff forces using the traditional approach are:
- 1. Develop the current Group Average Normalized Tendon Force vs. Time graph for each group of tendons.
He curve for each group consists of a straight line fit through the data points for each of the surveillances performed to date. Each data point represents the average of the normalized forces for the tendons in each group for a particular surveillanca. The curves are plotted on a semilogarithmic graph where the force losses versus time are essentially linear over the 40 yearplant design life. SigmaPlot software is used to generate the plots for the dome and hoop tendons. attached as Figures 2-1 and 2-2. The manually drawn graphs on pages si o confirm the accuracy of the SigmaPlot software graphs.

- - 2. Obtain the tendon force corresponding to the intersection of the time of the surveillance ofinterest and the straight-line projection of group average forte versus time results from previous surveillances.
Figures 2.1 and 2.2 are used to demonstrate the method for the dome and hoop tendon groups for the 5th tendon surveillance period. 4 The time durations from concrete placement to the planned surveillances are given in Table 1 below. Although the difference is minor, the time may be calculated for the actual planned start of the particular surveillare as described below for the 15 year surveillance scheduled to begin on approxunately April 1,1996. As the time since the performance of the SIT increases, the predicted tendon liftoff force becomes less sensitive to the actual time of the surveillance because the losses occur at a logarithmically decreasing rate over time. The majority of the losses occurred in the years immediately following stressing. For example, the hoop tendons at the 15 year surveillance are experiencing losses at the rate of about 0.45 kips per month. At the 20 year surveillance. losses will be occurrmg at the rate of about 0.3 kips per month. Therefore an estimate of the time within 6 months of the actual surveillance for use
- in deemnining the predicted liftoff forces for the 15 and 20 year surveillances will provide an accuracy better than 3 kips.
t An accuracy of 3 kips is acceptable and conservative. For perspective. 3 kips represents about 0.27% of the force in the tendon for a tendon having 1100 kips of force. l These conclusions for the hoop tcudons also apply to the dome tendons because the hoop tendons are experiencing losses i at a faster rate than the dome tendons as shown by a comparison of the slopes of the group force versus time curves (Figures 2-1 and 2 2) for the surveillances completed to date. I For the 25 year, and beyond, surveillances. the use of a time corresponding to the year of the surveillance to determme the t- predicted force will provide an accuracy better than 3 kips.

- 3. Calculate the predicted liftoff forces for the ladividual selected and adjacent tendons.
The predicted liftoff force is obtamed by subirecting algebraically the normalization factor for the particular tendon from 4 the predicted group average of the namahzed forces for the particular survedlance.The tendon normalization factors are obtained from Table 5 (Enclosure 8) of the current revision of SP 228 " Surveillance of Reactor Building Post-tensioning System" Normalization factors may be calculated for tendons not previously selected using the methodology in V.C. Summer Station Structural Calculation Book Z4-K.1:18.5. starting on page 98. This calculation for normalization factors may be performed manually or by computer using a spreadsheet.

DOC 1.5 RESULTS 1.The results of this calculation are shown in Table 4. Table 4 provides the Base Value predcted liftoff force for the selected and adjacent hoop and dome tendons for the 5th tendon surveillance scheduled for April 1996.The values for 0.95 Base and 0.90 Base are also shown.The same approach can be used for the liftoff force prediction for hoop and dome tendons for the surveillances beyond the 5th surveillances.
- 2. When calculating the predicted liftoff forces for a given surveillance, it is recommended that the data point for the nnrman=A group average liftoff force for the tendons in a group from the previous surveillance be added to the plot of data from all previous surveillances and the best fit straight line be reconstructed through all the available data points.
This means that a calculation to determine predeted liftoff forces for each surveillance will be done at any time in the interval following the previous surveillance and prior to the current surveillance. This work could be done at the time the group average curve is replotted during the evaluation of the data from a given surveillance. NOTES FOR TABLE 4 ON THE FOLLOWING PAGE:
- 1. Normalization factors are from Table 5 in SP-228.
- 2. Predicted forces are based on extrapolating the existing surveillance data from the first four tendon surveillances to the planned time for the 5th surveillance, i
