1.0 INTRODUCTION

s This report documents fuel examinations conducted during the End-of-Cycle 2 refueling outage at Palo Verde Nuclear Generating [

Station-Unit 1. The inspections were performed to fulfill examination requirements for E00-2 that are specified by the Palo Verde-1

'~

operating license. The inspections performed were dimensiona'i '

measurements' to characterize fuel rod and assembly growth. A total of 10 fuel assemblies were' inspected. Table 1 lists the assemblies and provides pertinent data for each.

2.0 FUEL ASSEMBLY DIMENSIONAL CHANGE EVALUATION l b

Fuel rod shoulder gap (distance between the top of the fuel rods and the bottom of the upper end fitting) and guide tube length

. measurements were made at Palo Verde-1 during the EOC-2 outage. A total of ten fuel assemblies were measured; two Batch B, six Batch C, and two Batch D. The specific fuel assemblies inspected are identified in Table 1. The shoulder gap of peripheral fuel rods on i d,

. the four faces of each fuel assembly was measured optically using a periscope, while each of the four outer guide tubes was measured using the guide-tube length measurement tool.

c '3 2.1 Pre-Shutdown Evaluation .

The shoulder gap evaluation for Palo Verde-1 Cycle 3 fuel is identical L '

to the method used for Palo Verde-1 Cycle 2 (Reference 1), i.e.,

l. remaining shoulder gap predictions were based on the minimum available ,

shoulder gap at the beginning of life, a conservatively high fuel rod I. growth prediction, and'a conservatively low guide tube growth

• prediction. These parameters are discussed in more detail below:

a. The minimum available shoulder gap at the beginning of life t L accouated for component dimensional tolerances, elastic l

compression of the guide tubes, and differential thermal expansion between the fuel rods and the guide tubes.

b. The conservatively low guide tube growth prediction utilized the

., lower 95% valut calculated using the methods described in ,

Reference 2.

c. The conservatively high fuel rod growth prediction was taken from the ANO-2 Batch C data as 0.21 inches of growth per unit of fluence (unyt or nyt x 10-21) (Reference 3). This growth rate represents more growth than the 95/95 upper limit for the 2-1

f-

.,; e v

i distribution of Batch C data from ANO-2. These data represent  ;

the fuel whose high fluence rods had the highest observed gruveth

~

rate of any fuel examined by C-E.

+ Implementation of this approach for the Palo Verde-1 fuel assemblies ,

showed that all shoulder gaps were predicted to have clearance at the end of Cycle 3. Therefore, if shed1 der gap and guida-tube length measurements taken on the ten Palo Verde-1 fuel assemblies support the applicability of the design basis, the third cycle fuel would be justified for Cycle 3 operation.

2.2 Dimensional Change Data

{

' The individual shoulder gap measurements are tabulated in Appendix A.

p Tables A-1 through A-10, along with a table of the length change for -

each measured guide tube, Table A 11. For each shoulder gap measured, the tabulation in Appendix A also contains the initial shoulder gap (measured value if available, otherwise the nominal value from the L desig a drawings), the resulting shoulder gap change (initial gap -

EOC-2 gap), the inferred fuel rod growth (shoulder gap change plus guide tube growth), fuel rod growth strain. (fuel rod growth / nominal BOL rod length), and the fuel rod's axial average fast fluence. Guide tube information (average growth and average fluence) is included at the bottom of each fuel assembly's shoulder gap tabulation. The s shoulder gap change data, guide tube grcwth data, and fuel rod growth

'A data are plotted relative to the appropriate fast fluence in Figures ,

1, 2, and 3, respectively. Also plotted on these figures are data R. obtained from the measurement of Palo Verde-1 fuel assemblies .

inspected during the E0C-1 outage (Reference 1).

l 2.3 Post-Shutdown Evaluation Guide tube length change data are shown in Figure 2 along with the limiting (lower 95% and upper 957.) length change predictions resulting 2-2

__ -. - - ..n_, .

a 4-1

• ~ I from the method described. in Reference (2). The figure shows that the measured data are all above the lower 95% predicted growth so it is conclumed that' it is conservative to use the guide tube length change model' when predicting limiting shoulder gap changes.

1 Fuel rod growth data are shown in Figure 3 along with the growth l

-- prediction taken from the ANO-2 Batch C data (0.21 inches /unvt). The [

figure shows that the higher fluence data are all below the design >

. basis and the trend of the data is for increased margin at higher fluences. Therefore, it.is conservative to use the fuel rod growth model when predicting limiting shoulder gap changes.

,' 5 The predictive models for guide tube growth and fuel rod growth have 7' been shown to be conservative relative to the Palo Verde-1 data.

Therefore,. the shoulder gao evaluation technique is acceptable for determining the fluence capabilities for Palo Verde fuel. 1he fluence capabilities calculated by the technique for all fuel assembiies in Cycle 3 exceed the peak fuel rod fluence at E00-3. Therefore, the i shoulder gap provided is sufficient and the fuel's operation in

' Cycle 3 will not cause complete closure of any fuel rod shoulder gap.

l y 3.0 SUMr4ARY AND CONCLUSIONS i

p Dimensional measurements of peripheral fuel rod shoulder gap and guide tube length were performed on 10 Palo Verde-1 fuel assemblies L following Cycle 2. Fuel rod growth data, determined from the measurements, indicates that the growth of high fluence fuel rods is ,

less than the growth predicted by the model used to determine design I limits for shoulder gap. In addition, the trend of the data is for increased margin between rod growth and the design basis at higher j fluences. Guide tube length measurements indicate that the measured I assembliesgrewfrom[ ]to[ ] inches during two cycles of exposure >

with average guide tube fluences up to 5.49x1021 n/cm2 (E >. 821 MeV)  !

and assembly average burnups up to 31.1 GWd/MTU. The measured guide 3 tube growth is greater than *.he lower 95% predicted growth that was t used to determine design limits for shoulder gap.

Based on the fuel assembly dimensional. measurements performed at EOC-2, the predictive models for guide tube and fuel rod growth have been shown to be conservative for Palo Verde-1 assemblies. As a result, adequate margin for shoulder gap reduction exists in all fuel assemblies designated for operation in Palo Verde-1 Cycle 3.
