REPORT ON DIFFERENTIAL SETTLEMENT INTRODUCTION The settlement of the safety-related structures at VEGP has been reviewed in the context of FSAR questions 241.17, 241.18, and 241,19 and SER sections 2.5.4.4.3 and 2.5.4.5.
These referenced FSAR questions have provided a discussion of settlement and settlement analysis based on data devel-oped in 1984 and early 1985.
This report has been prepared in accordance with the agreement, as' stated in the FSAR, to provide an update of total and. differential settlements three months prior tc Unit 1 fuel load.
This report includes comparisons between the following:
Precicted versus measured values of total gross o
settlement of the major seismic Category 1 structures.
Actual differential settlements.versus the dif-o ferential settlements used for design of safety-related piping passing between adjacent seismic Category 1 structures.
Basemat deformations due to measured differential o
settlement within a structure versus accepted criteria.
The report also contains a discussion of future settlement monitoring.
The VEGP settlement monitoring program consists of two permanent benchmarks installed as reference points for measurements and over 175 settlement markers located in the structures.
The locations of these settlement markers are shown on drawing AX2D55V001<,in Appendix A.
Markers are typically located in basemats; in the containment buildings l
they are located in the tendon galleries; in the NSCW cool-ing towers they were transferred up the outside of the structures as construction progressed.
Plots of measured settlement versus time are provided in Appendix A for all l
pertinent markers.
This report is based on the June 1986 submittal of settle-ment survey data.
Since settlement markers are typically l
monitored once every two months, these readings were made l
primarily during April and May of 1986.

SUMMARY
i A.
Total Settlement
[
The total measured settlements of the structures have f
been found to be well within the total settlements 1
[
predicted for these structures in FSAR Figure 2.5.4-8.
The maximum total settlement of any structure to date is the 3.6 inches experienced by NSCW tower 1A.
The maximum settlement predicted for this structure is 4.5 inches.
It is estimated that about 90 percent of the settlement which will occur has occurred for the-major power block structures.
B.
Piping Differential Settlement Actual differential settlements have been compared to the predicted di'fferential settlements used in the In cases design of piping passing between structures.
where the gross differential settlement (i.e.,
the total differential settlement between structures) the approached the design differential settlement, pipe closure spool installation date and the installa-tion date of the affected pipe supports next to the interface were used to develop the actual differential settlement applied to the piping.
In all cases the stresses induced by differential settlement were found to be less than those accounted for in the design of the pipe under applicable loading conditions.
C.
Differential Settlement Within Structures The effect of differential settlements within struc-tures on the structures themselves was addressed by reviewing the maximum net slope of the deflection curve (i.e., basemat. deformation) within large power block structures relative to the structure tilt.
The largest such ratio is 1/2020 for'the fuel handling building.
It does not approach the maximum ratio of 1/670 at which an assessment of possible induced structural stresses would be required, as stated in the response to FSAR question 241.18.
Therefore, it j
is concluded that deformation of the structures due to settlement is negligibly small.
D.
Future Monitoring Settlement marker monitoring for both units will be i
continued through the first year following issuance of an operating license for Unit 2 at a frequency of approximately 60 day intervals.
At the end of this a brief technical report will be provided to I
- period, I
the NRC with supporting settlement data and graphical plots.
An evaluation of settlement effects which i
would justify any proposed reduction in the frequency and number of markers monitored will also be provided at that time.

SETTLEMENT REVIEW A.
Total Settlement Figure 1 shows the total predicted settlement of the major seismic Category 1 structures (reference FSAR Figure 2.5.4-8).
Actual measured settlements are provided in parentheses near the location of an actual marker.
A comparison of the predicted and actual
. settlement values shown in Figure 1 indicates that the predicted settlements exceed the measured values by an acceptable margin.
It is estimated that about 90 percent of the settlement which will occur in the large power block structures has already occurred.
In addition, over 95 percent of the backfill has been placed.
It can be.seen from Figure 1 that if an addi-tional 10 percent of actual settlement were to be added to the values shown, the predicted settlement values would remain conservative.
Settlement graphs (see Appendix A) indicate that for the large power block structures the rate of settlement has substan-tially decreased, as expected, and for some, such as the auxiliary building, settlement has almost ceased.
It should be noted that several of the smaller Unit 2 miscellsneous Category 1 structures are either under construction or have been recently completed.
Some additional settlement is anticipated for these struc-tures prior to their leveling off.
The load histories for Category 1 structures, the turbine building and the radwaste buildings are provided in Table 1.
This table updates the data provided in FSAR Tables 241.17-1 and 241.17-2 Note that the structure load history data presented in Table 1 and shown graphically on the drawings in Appendix A are primarily based on concrete placement information.
Water loads for the tanks and NSCW cooling towers are.not included.
The total gross applied loads for these structures, including water, are given in FSAR Table 2.5.4-12.
The maximum settlement experienced by any structure has been the 3.6 inches of settlement recorded at NSCW tower 1A.
This is an example of the effect of loading from adjacent backfill causing structures to settle.
The approximately 90 feet of backfill surrounding the cooling tower loads the marl bearing stratum and lower sands with over 11 KSF.
Since the cooling tower is essentially a hole in the backfill, it settles as'the marl and lower sand strata are compressed by the weight of the backfill.
This-is evidenced by the fact that little additional settlement was recorded when towers 1A and 1B were filled with water (a rela-tively large load) as shown on the NSCW cooling tower settlement graphs in Appendix A.

f e
It is concluded that the total settlement of the power block structures is consistent with the predicted settlements.
Note that settlement markers used to develop the actual mesured total structure settlement shown in Figure 1 were installed over a period of several years as construction progressed.
Therefore, actual dif-ferential settlements, which cover identical time periods,-cannot be determined from Figure 1.
At VEGP, foundation design stiffnesses have been computed.using the interrelationship between basemat dimensions, soil modulus of elasticity, and other parameters.
Because much of the settlement experi-enced by the structures at VEGP results from loadings applied by adjacent backfill and structures, the use of field settlement measurements are not directly applicable in determining the soil stiffness under a structure.
It is therefore concluded that no meaning-ful comparison can be made between the design basis soil stiffnesses and soil stiffnesses based on field settlement measurements.
B.
Piping Differentials Figure 2 shows a typical example of the development of the gross differential settlement between two adjacent markers.
This figure is an update of data presented in FSAR Figure 241.18-2.
Gross differential settle-ments between adjacent seismic Category 1 structures were determined at approximately 90 key locations.
These gross differential settlements represent the differential settlement between two structures since the first day the markers chosen were both monitored.
Of the approximately 90 locations reviewed, only 14 gross differentials were found to be above 0.3 inches, 5 above 0.5 inches and none above 0.65 inches.
Typically, gross differentials of less than about one half the design differential were considered to be insignificant. ~For those cases where the gross dif-ferentials were not considered negligible, a review was made based on the installation date of the piping closure spool at the interface.
Table 2 provides a comparison between actual and design differential settlements for representative safety-related piping systems.
This table updates and amplifies the data originally provided in Table 241.18-1 of the FSAR.
Typically, if the gross differential settlement between two markers was con-sidered negligible, the interface was not included in l
4 t
the table, although some representative cases with small gross differentials have been included as examples.
Table 2 shows differential settlement subsequent to pipe and pipe support installation relative to the differential settlement for which the piping is designed.
For piping, only those settlement differ-entials which occur subsequent to its closure spool connection across an interface apply.
Likewise, the stresses in the pipe are affected by the settlement differentials subsequent to the date of the installa-tion of the affected supports at the interface, since these supports lock the pipe in place.
At VEGP, pipe stresses have been minimized by delaying the installa-tion of the closure spool and the interface supports as long as possible.
The location of the settlement markers identifying the interfaces are shown on draw-ing AX2D55V001 included in Appendix A.
In most cases, the differentials which may have actually affected the pipes are negligible.
It has been concluded that in no case does the actual dif--
ferential settlement presently exceed 75 percent of the differential settlement for which the piping is designed. Therefore, no additional evaluation of the piping is required at this time.
(See the response to FSAR question 241.13.)
C.
Differential Settlement within Structures Basemat deformation due to differential settlement within a structure is addressed by developing contours of equal measured settlement,for the large power block structures and estimating the amount of basemat defor-mation relative to the tilt of the structure as a whole.
This is done by determining the maximum net slope of the deflection curve (6/1) relative to struc-ture tilt for key sections through the basemat and comparing this value to published criteria.
Deformations represented by a maximum net slope of less than 1/670 are so small that no further review is required (reference FSAR Question 241.18).
An example of the calculation of the maximum 6/1 ratio for a structure, in this case the auxiliary building, is shown in Figure 3 This is an update of FSAR Figure 241.18-3 The maximum 6 /1 values determined for applicable VEGP structures as of June 1986 are as follows:
Auxiliary Building 1/4777 Fuel Handling Building 1/2020 Control Building 1/3032 5
The largest 6/1 ratio is 1/2020 for the fuel handling building.
This is well below the value of 1/670 previously discussed.
It is concluded that the effects of differential settlement on the VEGP structures are negligible.
It should be noted that only those structures whose size resulted in the installation of a large number of markers were suitable for the development of contours.
However, it is concluded that since the effects of differential settlement on large structures is negli-gible and since the data typically indicate that the remaining structures are settling uniformly, the effects of differential settlement on the remaining structures is also negligible.
L Future Monitoring The survey monitoring of settlement markers for both units will be continued through the first year follow-ing issuance of an operating license for Unit 2 at a frequency of approximately 60 days.
The survey accur-acy required will be first and second order leveling as is presently described in the VEGP construction specifications.
The level of accuracy of measurement of control monument and settlement marker elevations is first order leveling in accordance with accepted standard practice as described in NOAA Manual NOS NGS-3 and other accepted references.
Additional requirements are provided in the specifications.
It should be noted that while every effort has been made to read all markers at 60-day intervals, ongoing construction activities have sometimes made this impossible.
The typical reading frequency for the markers as a group continues to be at 60-day intervals.
Subsequent to construction, survey requirements will be implemented by a separate l
settlement monitoring program controlled by plant procedures, Allowable differential settlement limits are provided i
in the project design criteria.
Typical limits also j
appear in Table 2 under the column " Piping Design i
Differentials."
They are based on calculated expected settlements and a review of actual field data.
If allowable limits are reached, the affected piping and/or supports will be modified in the field to reduce the stresses to an acceptable level.
j Total predicted maximum settlements are provided in FSAR Figure 2.5.4-8.
If these limits are reached the situation will be reviewed to determine the cause of the increase and its effect, if any, on the
(
structures.

CONCLUSION It is concluded that settlement at VEGP is.within the limits predicted in the FSAR.
Differential settlements are typically small and within predicted limits.
The effects of differential settlement on piping are within design limits.
The effects of differential settlement on the structures themselves are negligible.
The settlement markers will continue to be read at the frequencies specified in the FSAR.
The effects of settle-ment will continue to be reviewed to ensure that they are within acceptable limits.
