20555 Re: Docket No. 71-6698 NFS-4 (NAC-1) Spent Fuel Shipping Cask
Dear Mr. MacDonald:
{
Nuclear Assurance Corporation hereby requests that Certificate of Compliance No. 6698, Revision No. 11, dated July 14, 1980 be revised to provide for statistical as well as direct comparison analyses of cavity
[
dimensional measurements.
In the course of performing the measurements on casks whose cavities are contaminated and radioactive, it has been found that it is impractical to repeat measurements at the precise locations of previous measurements.
This leads to differences in
[.
individual measurement values in isolated cases that exceed the 0.015 in.
tolerance specified in Revision No. 9 to the Certificate of Compliance.
Statistical analyses of repeated measurements of the cavity, however,
[
show that there has been no significant change in the cavity geometry which is what the measurements were originally intended to verify.
{
The difficulty came to light during the analyses of measurements taken in late August,1980 of the cavity of Cask NAC-lD. Because of the complexity of the field operations to perform the physical measurements
[
of the cavity, the isolated cases of measurement values exceeding the 0.015 in, tolerance were not imediately identified.
In fact, an initial review in the field of the measurement data indicated that the dimensional values were essentially the same as those reported for the original
[.
measurement of the Cask cavity performed in 1979.
On the basis of this initial review, we stated that the Cask was acceptable for use in accord-ance with the Certificate of Compliance and the Cask was returned to
{
service.
1l]13 l
A Mr. Charles E. MacDonald September 12, 1980 Page Two 4
During a more detailed analysis and reduction of the measurements in early September, the isolated and random instances of values in excess of the tolerances emerged.
In view of this finding, Nuclear Assurance Corporation withdrew the NAC-10 Cask from service September 5,1980, and continued to analyze the measurement data.
The results of NAC's analyses and comparison to the measurements made of this Cask in 1979 are described in the attached report number NAC-E-803.
Specifically, we request Paragraph 14 of Certificate No. 6698, Revision 11, be changed to:
- 14. At nominal intervals of at least six (6) months following the first shipment of irradiated fuel under Revision 9 and later revisions to Certificate of Compliance No. 6698, the licensee shall perform physical measurements of the cask inner shell and prepare a report of the results of the analyses of these measurements within one (1) month of performance of the measurements. The measurements shall be analyzed and compared to previous measurements reported for each cask and documented in Appendix C to NAC letter dated June 8, 1979.
Statistical and direct comparison analyses shall be performed and any cask whose inner contain" Jimensions are shown to deviate or to have changed <..jnificantly from the dimensions specified in License Drawing No.10080, Revision 19, or from previously measured dimensions, shall be withdrawn from service until such time as it is specifically approved for return to service by the Comission.
In accordance with the schedule of fees published on Page 7223 of the Federal Register, Volume 4, Number 35, dated February 21,1978, enclosed is a check in the amount of $150.00 for this administrative amendment.
Should you have any questions or if further information is desired, please contact me at your earliest convenience.
Very truly yours, NUCLEAR ASSURANCE CORPORATION f'

EXECUTIVE
SUMMARY
E In accordance with the requirements of Revision 11, Certificate of Compliance No. 6698 for the NFS-4 and NAC-1 Spent Fuel Shipping Casks,
[
the cavity of Cask NAC-lD was measured on August 21, 1980.
Every effort was made to perfom the reasurements and reduce the data for a direct comparison to similar measurements made in 1979; however, the measuring
[
equipment used in 1979 had been inadvertently buried and had to be replaced for the 1980 measurements.
Additionally, remote reading electronic gauges were used in 1980 in place of the direct reading dial gauges to reduce radiation exposure and operator fatigue during the measuring operations.
This is a report of the analyses performed on the 1980 measurement data and its comparison with the 1979 data.
Comparisons within the 1980
[
data sets were also made to ascertain the repeatability of the measurement method and to establish statistical relationships where applicable.
[-
It was found that there are considerable variations in the measure-ments. Statistical treatment of the values indicated standard deviations between individual data sets obtained in the 1980 campaign of 0.013, 0.014 and 0.015 inches. The standard deviation between the average of the 1980
[
values and values from 1979 was 0.008 inches.
Of the 174 " radial" readings taken, eleven (11) values exceeded the
[
0.015 inch tolerance when the 1979 and average 1980 values were compared.
On the basis of diameter, only seven (7) values exceeded the 0.015 inch tolerance.
[
Comparison of 1980 runs A and B revealed forty-six.(46) radial and thirty-five (35) diametral values exceeded the 0.015 inch tolerance.
[
Comparison of 1980 runs B and C revealed fifty (50) radial and twenty-nine (29) diametral values exceeded the 0.015 inch tolerance. The comparison of 1980 runs A and C revealed forty-five (45) radial and thirty-four (34) diametral values exceeded the 0.015 inch tolerance.
These comparisons indicate that there are larger deviations between 1980 data sets than there are between the average of the 1980 datt and
[
the 1979 measurements. This leads to the ' conclusion that direct comparisons of values from approximately the same location in the cask cavity can be misleading most probably because of the difficulty in resetting the equipment
[
to provide subsequent readings from previously measured locations.
Because of this inherent difficulty with the measurement method, a statistical treatment of the values obtained is the most practical means of detemining whether or not there have been any significant dimensional changes resulting from service sir the last cavity measurements were performed.
b h
i.
On the basis of the analyses of cavity measurements made in August.
1980, and comparisons ~ with the 1979 measurements, it is concluded that no significant change in the D Cask cavity dimensions have occured during its seven (7) months of service.
In view of the impracticability of measuring the cask cavity to the specified tolerance band of t0.015 inch with available equipment, a change to more practical evaluation criteria is
{
recomended in effect as follows:
"The measurements shall be analyzed.and compared to previous measure-ments reported for each cask and documented in Appendix C to NAC letter dated June 8, 1979. Statistical and direct comparison analyses shall be performed and any cask whose inner container dimensions are shown to deviate or to have changed significantly from the dimensions specified I
in License Drawing No.10080, Revidon 19, or from previously measured dimensions, shall be withdrawn from service until such time as it is specifically approved for return to service by the Commission."

1.0 INTRODUCTION
On August 21, 1980, measurements of the cavity dimensions of the NAC-10 cask were made.
Every effort has been made to perform the measurements and reduce the data in a manner that was identical to the
[
methodology employed when measuring the cavity of this cask in 1979; however, it was desired to replace the dial indicators with remote reading
[
electronic gauges to reduce operator exposure and fatigue during the active measurement. Additionally, the center rod, spider, and manipulating
{
equipment were new because the equipment used in 1979 had been buried inadvertantly. While a completely new set of equipment was used for the 1980 measurements, equipment calibration and operating procedures were
[
identical to that used in 1979.
b Three sets of data were taken to provide an indication of the effect of dismantling and assembling the measurement equipment.
The three sets
(
are characterized as follows:
[
A.
Original setup of equipment.
B.
All equipment removed and reinstalled.
C.
Traveling spider removed and reinstalled.
{
[
Reduction of the data was approached from two points of view.
The first determined the satisfaction of the ovality and surface linearity b
constraints that are a part of the license for this cask. The second approach to data reduction determined the change in cavity dimensions
[
among all sets of data.
[
A summary of the significant cavity parameters and the corresponding values from the 1979 measurements is presented in Table 1.
All of the
{
dimensions showed no significant change during the six months service.
A summary of the changes in the cavity measurements is presented in Table 2.
These data show that there are variances in the measurements between data sets taken during the 1980 campaign that exceed the desired
1 I
precision of the inspection.
Because of the variance inherent in the l
measurement method, statistical treatment of the measurement data was necessary to reach any conclusions regarding changes in the cavity resulting from normal service.
I Principal emphasis was given to comparisons between the 1979 data set and the average of the 1980 data sets. The 1980 data sets were also compared to provide an indication of variances to be expected from the I
inherantly difficult and imprecise measurement procedure.
Statistical evaluations were made to demo 1 strate that the 1979 measurements are a part of the same population ar, those made in 1980 and hence suffer from I
the same variances.
The conclusions reached from analyses of the measurement data are:
1.
The cavity dimensions and configuration have not changed during seven months of service.
2.
The criteria for allowable deviations in dimensions listed in Certificate of Compliance No. 6698 amendment 9 are impractical I
because of the inherent difficulty in performing cavity measure-ments with available equipment.
Recommended criteria for evaluating the continued stability of the NAC-1 cask include statistical treatment of measured data with limited comparison of individual measured dimensions from comparable locations in the cask cavity.

7 2.0 MEASURED DATA The cavity dimensions of the NAC-10 cask were measured utilizing similar techniques and equipment to that reported in NAC-E-793.
Since the purpose of this report is to compare the measurements reported in NAC-E-793 to the current sets of measurements, the results presented in NAC-E-793 will be presented along with the nialts of the current measure-ments. A summary of the instrument calibration data is presented in Appendix B and tabulation of the electronic gauge readings is presented in Appendix A.
These dimensions are recorded in millimeters and converted to inches. Appendix C is a report of the Quarterly Maintenance and Cavity Measurements from the field representative.
2.1 DIAMETER The electronic gauges on the spider were located so that pairs of readings resulted in a measurement of the cask cavity diameter.
The measurements of the. ameter are more precise than the measurement of 1
radius since variations in the position of the center of the spider are cancelled.
The measured diameters at each axial location are tabulated in Tables 3 through 7.
Drawing E10080 includes a tolerance on the cavity diameter that restricts the permissible values to 13.500 to 13.750 inches. A summary of the extremes of the measured diameters and comparison to the limits on the drawing is presented in Table 1.
2.2
'VALITY I
The inner cavity is a pressure vessel that must conform to Class II of the ASME code for pressure vessels.
This section of the code requires that the ovality be less than the smaller of (D + 50)/200 or D/100.
In this case the limit of D/100 is more restrictive so all further references to the ovality limitation will use 1% of the nominal diameter as the limit.
The ovality of the cavity is defined as the difference between the maximum I
l
L 3
[
and minimum of the measured diameters expressed as a percentage of the mean
[
diameter.
The cavity ovality of the cask is tabulated in Tables 8 through
- 12. A tabular summary of the largest ovality of the cask is presented in
[
Table 1 which also includes the ovality limits of the ASME code.
2.3 SURFACE LINEARITY
{
['
The measured data are a direct measure of the surface linearity of the cask cavity. During inspection in a machine shop, a straightedge would be placed against the cavity wall and the deviations between the straightedge ~and wall measured. The displacement between a straight line and the measured radius are tabulated in Tables 13 through 17. The
[
straight line was selected to pass through the smallest radii so that it is equivalent to a straightedge resting on local high spots.
[
The drawings that are part of the Safety Analysis Report (E10080)
{
include a tolerance of 0.130 inches on the surface linearity of the cask cavity and the diameter of the cask cavity. A tabular summary of the maximum surface linearity is presented in Table 1 which also includes the
. limits imposed by the drawings.

3.0 COMPARISON OF MEASUREMENTS f
The most significant aspect of the current cavity measurement is l
(
the comparison between these data and the data reported in NAC-E-793.
Similarly, comparisons between the current sets of data are necessary to
(
establish a measure of the uncertainty inherent in the measurements.
[
The data reported in NAC-E-793 are referred to as 1979 data and 3
the current sets of measurements are referred to as 1980 A,1980 B aad 1980 C for easy reference.
Comparative radial measuremeats between the 1979 and the average f
1980 values are listed in Table 18.
The mean difference between the measurements is 0.001 inch with a standard deviation of 0.008 inch. The
[
maximum deviation between measured " radii" was 0.024 inch and there were a total of eleven radial measurements exceeding the 0.015 inch tolerance.
f Comparison of " radial" measurements is not as meaningful as comparison of diametral values because of the possibility of the control bar of the inspection device not being coincident with the center line of the cavity.
Diameters were calculated by combining the radial values of 180 angles and are compared with 1979 diameter values in Table 19. The mean difference between the 1979 and average 1980 values is 0.002 inch, while the standard f
deviation is 0.009 inch. The maximum deviation between the diameters calculated from 1979 values and the average of the 1980 values is 0.026 inch
(
with only seven diameter values exceeding the 0.015 inch tolerance.
[
Comparisons were made between individual measurement sets obtained in the 1980 compaign to evaluate the repeatability of the measuring method.
These comparisons are tabulated in Tables 20 through 25. These comparisons show a wider variation in radial and diametral values between individual measurement sets taken in 1980 than between the 1979 values and the average of the 1980 values. This is somewhat surprising in view of the equipment differences between the 1979 and 1980 campaigns; however, it does illustrate b
the point that these measurements are not repeatable without a significant error band, f

4.0 CONCLUSION
S AND RECOMMENDATIONS Direct comparison of measurements taken during the 1980 campaign b demonstrate that the measurement equipment and method result in variances that. exceed the intended precision of the inspection. There is no [ statistical difference between the dimensional measurements made in 1979 and the measurements made in 1980 after seven months of operational {- service. This is demonstrated by the deviations in measurements made during three separate measurement operations in 1980 between which the cask saw { no service and the only change to account for the different values was the reassembling of the measurement equipment. [ It is concluded that the cavity dimensions have not changed during the seven months of service and there has been no change in the configuration b of the cavity of the cask. The cavity diameter, ovality and surface linearity show no statistically significant changes and the statistical [ evaluation of the changes in radius indicate that the measurements made in 1979 are a part of the family of data that also includes all three [ sets of measurements made in 1980. { It is further concluded that the criteria for allowable deviations in measurements listed in Amendment 9 to Certificate of Compliance No. 6698 are not attainable with the measurement equipment available. It is therefore recomended that these acceptance criteria be changed to the following: The measurements shall be analyzed and compared to previous measurements [ reported for each cask and documented in Appendix C of NAC letter dated June 8, 1979. Statistical and direct comparison analyses shall be [ performed and any cask whose inner container dimensions are shown to deviate or ':s have changed significantly from the dimensions specified { in License Drawing No.10080, Revision 19, or from previously measured dimensions, shall be withdrawn from service until such time as it is specifically approved for return to service by the Commission.

y The electronic gauges were calibrated prior to the initiation of the measurement. The calibration consisted of three measurements. The first is the measurement of the diameter of the central shaft which averaged 1.999 inches with a maximum variation of 0.0002 inches during six independent measurements. The remainder of the calibration consists of determining the distance from the center of the shaft to the null point for the electronic gauges. Measurement of the distance to the null point begins by locating the shaft on blocks above a flat surface with a micrometer. Then calibrated gauges blocks of varying heights are inserted under the instruments and the responses are recorded. Extrapolation of each curve gives the dimension from the shaft to the point where the instrument reading is l zero. The resulting dimensions are presented in Appendix A as the reference dimension for each electronic gauge. I { { [ r L l I r L r L: P i

NAC-1D Cask Quarterly Maintenance and Cavity Measurements l Sumary During the week of August 17, 1980, a quarterly maintenance program and cavity measurement were performed on the NAC-1D cask at San Onofre. Three measurements were performed on the cask cavity to obt.a.in a better understanding of the measurement systems actual repro-l aucability. After the first measurement was performed, the measuring equipment was removed from the cask and replaced. A second measure-ment was then performed. For the third measurement only the spider was removed and replaced. Upon comparison with the original cask straightness data, the results between the three measurements varied significantly; with a range of -0.056 to +0.035 inches. However, the results of the individual I measurements showed data points from the third measurement to be within 0.015 inches of corresponding points from the original meas-urement. This met the 10.015 inches criteria as stated in our cask certificate of conformance. Af ter picking up the new cask cavity measuring equipment with digital indicaters at the LAX airport, we arrived at San Onofre on August 18, 1980. The cask was I being raised onto the recently resurfaced turbine deck. However, when they had the turbine deck resurfaced on August 15 and 16, a non-skid surface was specified. This surface unfortunately would not allow the' air pallet to glide I down the turbine deck. Since the cask on the air pallet could not be moved on this surface, it was decided to isave the turbine deck resurfaced again before any shipments would be made. This delay in schedule allowed us to set up our cask cavity measurement equip-ment and calibrate the individual gauges. Because these gauges had not been previously calibrated, readings were taken at every 0.100 inch increments; thus, I allowing the full scale range to be calibrated. Since the cask cavity measure-ment was to be done at San Onofre and witnessed by NRC, it was decided that San Onofre Site Quality Assurance personnel should witness the gauac calibration. During the morning of August 20, 1980 calibration of the gauges was repeated and witnessed by San Onofre site Quality Assurance personnel. We were able to duplicate the incremental reading of gauges for each gauge block within t0.01m (10.0004 inches). By mid morning of August 20, 2980, the turbine deck surface had been ground smooth and was acceptable for cask movement. The cask was then transferred into I the cask decontamination area and was given to us to perfonn our quarterly I
M Memo to C. R. Johnson September 10, 1980 Page Two maintenance. The lid holts were first tighten to 1000 pounds using the San Onofre supplied calit rated torque wrench. The cask cavity and the lid gasket i j was successfully pressurized with water to the required pressures as stated in the qua: 'arly maintenance procedure. The gauge used to pressure levels was suppliea by San Onofre and calibrated on August 19, 1980. A copy of the com-pieted quarterly maintenan.e form, together with the gauge calibration is attached. Once the cask maintenance was completed, the decontamination process of the cask < tarted. The cask cavity was initially drained of coolant and then refilled ( with an emnonium oxalate solution (TURC0 4521). This solution was then recir-culated within the cask. The solution was pumped from the bottom drain valve into tha top vent valve. This solution was allowed to recirculate overnight. [ On the morning of August 21, 1980, the cask cavity decontaminated solution was then drained from the cask. The cask head was then lifted off and the cavity internals washed with demineralized water. Since the cask cavity with the liner ( read about 150 mr/hr at the cask surface, the decontamination solution appeared to have been effective. However, the circumferencial portion above the vent valve was not decontaminated as effectively. This area had to be cleaned with smear paper. The liner was then removed and placed into the spent fuel pool. ( Since there was a possibility that some of the decontamination solution remained in the cask, the cavity and the liner were washed with dimineralized water during the liner removal operation. The bottom portion of the cask liner still { read between 1 and 3 R/hr on contact. Both the liner and cask cavity still appeared to have a greasy coating on their surfaces. Once the liner was removed, the cavity surface was washed with paint thinner to remove this surface [ coating. Again the cask cavity was washed with demineralized water. This process decontaminated the cask cavity down to acceptable working limits for the cavity measurements. Reading of 50 mr/hr and 75 mr/hr were obtained at the top of the cavity and within the center of the cavity, respectively. By 1300 hours, August 21, 1980, the measurement equipment was installed within the cask cavity. Once the precision bar was centered at the top of cask cavity, { the actual measurement of the cavity started. Readings were taken at 4.5 and 6.5 inches from the top of the cavity and then at 6 inches intervals over the remainder of cavity length. These readings were witnessed by the site NRC I & E { inspector (Lew Miller). Once the measurements were completed, t,>ider was brought back up and readings at four levels were redone to cheu, t.N repro-ducibility of the measurement system. ( The measuring equipment was then completely removed from the cask and then rein-stalled. Again the precision bar was centered at the top and the readings were taken at the predetermined locations in the cavity. Once the measurements were { taken, the readings at four locations were repeated while the spider was brought into its up position. [ After the spider'was removed from the cask cavity, it was then replaced and the precision bar recentered. A third set of readings were then taken. Again four locations were repeated while the spider was brought into its up position.
i 1 l. l Memo to C. R. Johnson I September 10, 1980 Page Three l The data from the three measurements (shown in Tables 1, 4 and 7) was reduced to determine the cask straightness at six different positions. The variation of the cask straightness was determined to be the difference between a calculated I reading as determined from a straight line drawing between the first and last measured point and the actual reading at given height locations. The cask l straight >xss data from each of the three runs (shown in Tables 2, 5 and 8) was I compared with the 1979 cask straightness data previously obtained with the results shown in Tables 3, 6 and 9. I Tne histogram of the variance between the first measurement and the original I straightness data is shown in Figure 1. This comparison gave a mean value of 0.0049 inches with a standard deviation of 0.0113 inches for the 174 data points examined. The individual data points gave a range of 0.0810 inches with a minimum value of -0.056 inches and d maximum value of 0.025 inches. Examinati on of the camparison data showed one point (30 at 120.5 inches) to be signif-icantly cut of the normal statistical range of the remaining data (greater than 4 sigma) and due to the possible transcription error (9.08 versus 9.98), it was determined that this data point should not be included in the analysis. The resulting histogram of the comparison of 173 data points with the original data is shown in Figure 2. By the elimination of the one data point the mean value I changed to 0.0046 inches with a standard deviation of 0.0107 inches. H wever, this data still indicated a range in the data points of greater than 10.015 inches (-0.027 to 0.025 inches) requirement specified in the cask certificate of compliance. The histogram variance between the second measurement and the original straight-I ness data is shown in Figure 3. This comparison gave a mean value of -0.0034 inches with a standard deviation of 0.0149 inches for the 174 data points examined. The data points had a range in the data points of 0.076 inches 4 (-0.041 to +0.035 inches) which was greater thar, the 10.015 inches requirement I as specified in the cask certificate of compliance. The histogram variance between the third measurement and original straightness data is shown in Figure 4. This comparison gave a mean value of 0.0002 inches with a standard deviation of 0.0074 inches for the 174 data points examined. The individual data points gave a range of 0.028 inches with a minimum value of I -0.014 inches and a maximum value of 0.014 inches. Therefore, this result showed the data points from the third measurements to be within 0.015 inches of the corresponding points from the original measurement. This measurement meets the criteria as stated in our cask certificate of compliance; and the cask I should be acceptable for shipment. Figures 5 and 6 show the composite variance of the data points from the three I measurements as compared with the original straightness data. This comparison gave a mean value of -0.0027 inches with a standard deviation of 0.0118 inches and mean value of -0.0026 inches with a standard deviation of -0.0115 inches for I the 522 and 521 data points, respectively. The elimination of one data point in this large population did not affect the statistical results appreciably. Without the -0.056 inch data point, the range for the remaining 521 data points was 0.086 inches (-0.041 to -0.035 inches).
Memo to C. R. Johnson September 10, 1980 Page Four Once the cask was determined to be acceptable for shipment, the cask cavity measurement equipment was removed from the cask. On August 22,19P7 the cask was placed back into service. The liner and the cask lift were thea replaced. However, the cask was not loaded with a fuel _ assembly until later that day due to paperwork missing on the spent fuel crane cable. Once this paperwork. was received, the actual cask loading operation started. The loaded cask departed San Onofre for Morris at 0030 hours on August 23, 1980.
