EXECUTIVE

SUMMARY

( All available information and measurement data on the settlement moni-toring of E. I. Hatch Nuclear Power Plant structures were compiled, and the data plotted and analyzed. The applicable Technical Specification,

{ the Final Safety Analysis Report, and previous related studies were reviewed as part of this comprehensive study.

[

The results show that the building settlements have essentially stopped

[. several years ago, and are all below the predicted maximum values. The differential settlements are also below the allowable limits. Based on the conclusion of no significant building settlement for the past several years, it is recommended that the current Technical Specification 3/4.7.8 be replaced with a Plant Operating Procedure. The outline contained

{ t within this report is intended to serve as a basis for this recommended change.

1. 0 INTRODUCTION AND SCOPE As required by Technical Specification 3/4.7.8, entitled

[ " Settlement of Class 1 Structures," Georgia Power Company (GPC) is committed to monitor total and differential settlements of all Class 1 structures at E. I. Hatch Nuclear Plant Unit 2

{

(HNP-2). The technical specification was issued in 1978 and has included the monitoring of not only the Unit 2 Class 1

[- structures but other major plant structures. The structures included are listed below:

o Reactor Building, Units 1 and 2

[

o Turbine Building, Units 1 and 2 o Radwaste Building, Units 1 and 2 o Control Building o Diesel Generator Building

[ o Intake Structure ;

o Offgas (Main) Stack

{

The technical specification, which is included as Appendix A, outlines the monitoring and the resulting potential action requirements for the Class 1 structures.

The tabulated settlement data for the above structures is

( .

contained in Appendices B through F. For information, the tabulated settlement data for the Condensate Storage Tanks l Units 1 and 2, the Liquid Nitrogen Storage Tank, and the Waste Gas Building are included in Appendices G and H.

E The major structures at Plant Hatch were constructed in the early to mid-1970's, with commercial operation for Unit 1 and Unit 2 being December 1975 and September 1979, respectively.

Since the start of commercial operation, the measured settle-ments of all structures have stabilized to nearly constant values. In light of this, the purpose of this report is to perform a comprehensive review of the technical specification I in conjunction with the settlement measurements recorded to date for each structure. In addition, it will be determined if changes can be made to Technical Specification 3/4.7.8, while continuing to assure that plant safety and operations are maintained. The following items will be addressed:

o Total Settlement o Differential Settlement Across Structures (Tilt)

I o Penetration Differential Settlement (Between adjacent structures and between structures and soil) o Frequency of Readings o Accuracy of Readings o Technical Specification 3/4.7.8 2.0 PREDICTED SETTLEMENT E

Settlement predictions were made for the structures under con-sideration. Generally, the prediction utilized stress values calculated in accordance with the Westergaard theory and considered stress overlap from all nearby foundations. Struc-tural dead loads plus live loads were considered in the stress calculation. The soil compressibility characteristics were determined by one-dimensional laboratory consolidation tests.

E E

Detaiis of the settlement estimate are given in the Final Safety Analysis Report (FSAR) Section 2A.5.3, Reference 1. l Table 1 presents the predicted total settlement for each structure under consideration.

E 3.0 SETTLEMENT MONITORING DATA

'E The conclusions and recommendations of this report are based on settlement monitoring data supplied by GPC and information I contained in the FSAR Section 2A.S.3. In most cases, informa-tion from these two sources provides a complete record of settlement for each structure, except for the following:

o Reactor Building Unit 2 - ao data was available for 1973 and 1974 I o Turbine Building Unit 1 - no data was available for 1972 and 1974 I

o Control Building - no data was available for 1972 l o Diesel Generator Building - no zero readings were available for the NE and NW benchmarks o Radwaste Building Unit 1 - no data was available for 1972 o Intake Structure - no data was available prior to mid-1978 5

In all cases, however, sufficient information is available to determine settlement trends and maximum settlement for each structure and to determine what future course of action is required.

E E

E

E 4.0 TOTAL SETTLEMENT Measurements of structure movements were, in most cases, made once each month during construction and have been made twice a year since each structure has been completed. The measurements are currently being made on four settlement benchmarks established on each structure, except for the Offgas (Main) Stack where there are only three benchmarks. Figure 1 shows the relative lB l5 cati ns f while Figure 2 shows the relative locations of each benchmark ch benchmark on the power block structures, for the Offgas (Main) Stack, Diesel Generator Building and Intake Structure.

The tabulated total settlements for each structure are given in Appendices B through H. The values were determined by subtrac- l ting the survey reading for a given date from the total set-tlement reference elevation established near the start of construction. However, in some cases (genere.lly prior to I 1975), only the mr.asured settlements were provided in the supplied data. Further, where tabulated survey data were not ,

available, settlement figures from the FSAR were used to l

estimate the movement of a particular benchmark.

I Several assumptions and adjustments to the reference elevations l werr. made in order to determine the actual benchmark movement.

For example, referring to Appendix B, the reference elevation for the southwest marker of the Reactor Building Unit 2 was I 130.002 feet. On January 15, 1980, the survey reading indi-cated the southwest marker had settled a total of 1.884 inches (0.157 feet) since the beginning of settlement monitoring. On the same day, a new settlement benchmark was established. The surveyed elevation of 129.859 feet for the replacement bench-mark was adjusted to 130.016 feet (129.859 + 0.157) to account for the settlement which had already taken place. Subsequent E

E readings were then compared directly to the new established reference elevation of 130.016 feet. Details of these assump-tions and adjustments are given in Appendices B through H. l Settlement versus time curves for each structure, prepared from the data contained in Appendices B through H, are presented as Figures 3 through 16. Common vertical and horizontal scales E were used for each plot for ease of comparison of relative amounts of movement with respect to time.

The ratios of the measured settlements (both historical maximum and as of July 1986) to the predicted settlements are shown in l Table 1. The ratios are highest at the Unit 1 Reactor and Turbine Buildings and the Control Building. All three of these structures were completed during the early construction stages at Plant Hatch. The ratios for the Unit 2 structures are lower E due to higher predicted Unit 2 settlements, and because Unit 1 structures partially prestressed or preloaded the soil beneath I the Unit 2 structures prior to the start of Unit 2 construction and settlement monitoring.

As shown on Figures 3 through 16, the settlement curves have l flattened out, indicating that no measureable settlement of any structure has occurred for at least the last eight years. It l is believed that the slight cyclic movements taking place are due to the inherent variations associated with optical survey, including seasonal variation with temperature. These curves E demonstrate that the structures have essentially completed their settlements, and that the measured settlement values will not reach the predicted values.

5.0 DIFFERENTIAL SETTLEMENT ACROSS STRUCTURES (TILT)

Differential settlement across buildings will only be con-sidered for those structures referenced in the E. I. Hatch 5

t l

Nuclear Plant Unit 2 (HNP-2) FSAR, Section 2A.5.3.2. Those structures are:

I o Reactor Building Unit 2

[ o Radwaste Building Unit 2 I o Turbine Building Unit 2 o Control Building 1

o Diesel Generator Building I

o Offgas (Main) Stack c Intake Structure i

Details of the criteria used to establish the allowable differ-ential settlement across each structure are not discussed here, l'

but can be found in FSAR Section 2A.5.3.2.1, and in Reference 2.

I To determine the actual differential settlements, tilt reference elevations have been established for the settlement benchmarks l in each building. The term " tilt reference elevation" used here is the elevation which can be compared with current survey i

l elevation readings to indicate the existing degree of differential settlement across the structure. These tilt reference elevations I

, are based on the survey readings taken at or near the construction completion date of each building. This date corresponds to the time when the structure is assumed to be properly aligned, both l with respect to itself and to any adjacent building. Existing differential settlement across the structure will be measured from this reference date and compared with the allowable values.

I 1

I l

I Using the tilt reference elevations and the latest survey values, the settlement of each benchmark from the reference date to the present time can be determined. A comparison of the settlement values of any two benchmarks within a building provides the differential settlement or tilt between the benchmarks.

E A comparison of the existing and allowable differential settle-ments is shown in Table 2, along with the reference date E (approximate completion date of each structure). The results indicate that there has been little differential settlement to date and that the existing tilt is well below the allowable.

Further, by examining the settlement curves (Figures 3 through 16), it is apparent the differential settlement across all l

{

structures will not significantly change in the future, as each structure has reached an equilibrium point and no additional measureable movement is expected.

E 6.0 PENETRATION DIFFERENTIAL SETTLEMENT t

I Penetration differential settlements for those structures 1

referenced in the FSAR Section 2A.5.3.3, will be considered here. The structures considered are the same as listed in Section 5.0. The only exceptions are the penetrations between each Reactor Building, which will also be addressed.

Details of the criteria used to establish the allowable differ-lE ential settlement for the penetrations are not discussed here, but can be found in FSAR Section 2A.5.3.3.1 and in Reference 2.

Differential settlements of the penetrations since installation were measured by assuming the settlement of the penetration to f be the same as the settlement of the nearest benchmark. For each penetration exiting from the structure into the soil, reference was made to the appropriate value of settlement given in Appendices B through F. This value of settlement was l

E i l

E compared to the latest (July 1986) movement of the benchmark l (either up or down), which had occurred since the date of pene-tration completion. If rio reading was taken for a benchmark on l the completion date, then the previous reading was used as the reference value. It should be noted that the maximum movement is not necessarily the movement that occurred between the penetration completion date and the present reading. This is because the settlement pattern of all of the benchmarks is, at present, nearly level, with dips and peaks due to inherent I survey error and thermal expansion and contraction of the structures. As a result, the maximum settlement frequently occurs in one of the dips measured prior to the present readings.

For penetrations passing between adjacent structures, the settlement of the benchmarks closest to the penetration on both structures must be considered. The settlement values of the two benchmarks from the penetration installation date to present are compared to the latest (July 1986) movement. A l review indicates that maximum differential settlement does not necessarily occur on the most recent date for the reasons stated in the previous paragraph.

The ratios of the maximum measured settlement to the allowable settlement for the penetrations have been calculated and are presented in Tables 3 through 10. These tables show that all of the measured settlements are presently well below the allowable values, with the large majority being less than E 20 percent of the allowable. These low ratios reflect two related factors: first, the majority of the penetrations have been installed since late 1976; and second, building settlement values since late 1976 have been very small.

5 Examination of the settlement curves on Figures 3 through 16 l shows that the differential settlements at the penetrations have not changed significantly in the last eight years. Since l E

E

l l

the curves indicate that the structures have essentially completed their settlement, this pattern of "no change" is expected to continue in the future.

l 7.0 FREQUENCY OF READINGS l

Presently, the benchmarks are being surveyed twice a year, except when the benchmark is temporarily blocked by equipment

{

or if radiation is high, as in the case of the Offgas (Main)

I 1

Stack. Generally, the readings are taken near the beginning of l

the year, in January, and in the middle of the year, in July.

This monitoring pattern has resulted in what appears to be l

l small cyclic temperature fluctuations. l 8.0 ACCURACY OF READINGS The settlement values are determined by measurements which are ,

l l compared with known elevations at established onsite reference I

l benchmarks. The locations of the reference benchmarks are shown on Figure 17. The elevations of the reference benchmarks l

l were originally established from a United States Geological l Survey (USGS) benchmark in Toombs County. The reference benchmarks are situated in the yard in such a way as to avoid l

accidental displacement and facilitate the settlement surveys of the Class 1 buildings. They are far enough away to avoid settling with the Duildings. Precautions were also taken to l

provide proper soil and anchorage conditions to ensure the stability of the benchmarks. However, there appears to be no procedure for periodically checking the elevations of the reference benchmarks.

l Plant operating procedure 43RC-SUV-001-2 established a detailed I method for monitoring settlement of Class 1 structures for HNP-1 and HNP-2. A series of special drawings was prepared to clearly locate the benchmarks and establish a fixed survey route. These drawings are referenced in the procedure. The l

l l - - - -

E l

acceptance criterion for closure error is 0.005 foot. The procedure establishes as much consistency as possible from one survey to the next in order to make any change or abnormality l immediately apparent. However, even with tight controls, survey " errors" and variations are inevitable. These can be divided into three categories:

o Instrumental errors o Personal errors l

o Natural variations f

Ideally, the plant operating procedure eliminates the instru-mental and personal " errors" through a system of checks and balances. The natural variations, however, are unpredictable.

Surveying experience indicates the variations associated with I

optical leveling can be as high as 11/8 inch (Reference 3),

which is about the level of accuracy that can be expected for a l first order survey traversing about 1/4 mile (Reference 4).

Most of this is more than likely due to natural " variations,"

l such as temperature fluctuations, that occur during the survey.

l 9.0 TECHNICAL SPECIFICATION 3/4.7.8 In order to understand the development and implementation of I

the technical specification, a brief chronology of significant events is given below:

k o June 13, 1978: Nuclear Regulatory Commission (NRC) issued l the Plant Hatch Unit 2 Technical Specification for Monitoring Building Settlement 3/4.7.8.

o June 15, 1978: GPC requested Bechtel to ". .. investigate the potential significance of building settlement and review the specification that the NRC issued . . " .

1 10 1

I l

o November 1978: dechtel issued a report entitled, " Proposed l Technical Specification, Settlement of Category I Struc-tures," as an outgrowth of the June 15, 1978 GPC request.

l o December 1, 1978: GPC transmitted to the NRC the proposed changes to Technical Specification 3/4.7.8.

l o March 30, 1979: NRC requested additional information re-l garding December 1, 1978 GPC submittal.

I l o July 20, 1979: NRC requested additional information re-garding December 1, 1978 GPC submittal.

i o August 14, 1979: GPC responded to March 30, 1979 NRC i request.

o October 8, 1979: GPC responded to July 20, 1979 NRC l

request.

l o September 27, 1982: GPC proposed to the NRC deleting l Technical Specification 3/4.7.8 and a withdrawal of sub-j mittals on that subject.

o December 7, 1983: GPC outlined to the NRC a procedure to be used for continuation of settlement monitoring via a I Plant Operating Procedure.

o May 4, 1984: GPC reported to the NRC a possible error in l the December 7, 1983 submittal and discrepancies between the FSAR and Technical Specification 3/4.7.8.

l o October 1985: GPC requested that Bechtel review the set-tlement issue, including all submittals to the NRC on building settlement, and recommend changes needed to Technical Specification 3/4.7.8, if appropriate.

1 11 l _ - - -

o December 18, 1985: GPC reported to the NRC that the December 7, 1983 submittal was incorrect. The correct information was supplied.

o April 4, 1986: GPC reiterated the September 27, 1982 submittal to delete Technical Specification 3/4.7.8 and monitor building settiemeat via a Plant Operating Procedure.

The original technical ".pecification, which was initially I reviewed in 1978, is the same Technical Specification 3/4.7.8 still in use today and given in Appendix A. The only difference between the two is that the original 1978 version gave an allowable differential settlement of 3/4 inch for all structures, whereas the current version does not give allowable differential settlement values. GPC has initiated action with the NRC to resolve this difference. Further, GPC has committed to monitor building settlement in accordance with provisions given in the FSAR, Section 2A.5.3, via a plant operating procedure rather E than a Technical Specification.

It must be emphasized that whether or not differential settle-ment is addressed in the Technical Specification, it does not alter the fact the structures are not settling and are not expected to settle in the future. It is for this reason that the Technical Specification can be eliminated. !

10 0 CONCLUSIONS AND RECOMMENDATIONS E

The settlement curves on Figurcs 3 thro, ugh 16 demonstrate that the structures under consideration (includirg the Condensate Storage Tank Units 1 and 2, liquid Nitrogen Storage Tank, and the Waste Gas Building) are not settling and have not been settling for at least the last eight years. In every case the measured total settlement (Table 1) for each structure is less than the predicted value. The small movements that have taken ,

place recently appear to be due to temperature fluctuation and B i 12 E

E l

\

the inhe.'ent variation in optical surveys. Further, no appreci-l able tilt has occurred in any of the structures. In all cases, the ratio of measured differential settlement to the allowable l differential settlement (across structures) is less than or l equal to 30 percent (Table 2). The ratio of the measured l l differential settlement to the allowable differential settle-ments (for penetrations) is less than oc equal to 59 percent !

I (Tables 3 through 10). In summary, the structures have expe-l g rienced all of the appreciable settlemer,t that is expected to N occur, and any remaining measured movement will be due to l survey inaccuracies and/or temperature fluctuations.

l In conclusion, from a purely geotechnical standpoint, Technical Specification 3/4.7.8 can be eliminated in its entirety and j settlement monitoring of the structures can be accomplished through a Plant Hatch Operating Procedure.

l It is recommended that the new procedure address not only total B settlements, but differential settlements as well. The basis I for the plant operating procedure is the December 1, 1978 submittal from GPC to the NRC, Reference 5, with some minor l revisions. Note that the provisions in Reference E are the same as those in Reference 2 and in Section 2A.S.3 of the FSAR.

l The recommended criteria to be used to evaluate the settlements are as described below:

I A. Surveillance Requirements l

The surveillance requirements for all settlement benchmarks is recommended to be once a year through 1988, once every 2 years through 1992, then once every 5 years thereafter, except when an unusual meteorological or seismic event occurs, in which case the structures should be surveyed as soon as possible. The surveys should be conducted at the same time of the year to avoid any fluctuations due to l l

13 l . - _ _ _ .

[

seasonal temperatures. The existing surveillance require- I b ments 4.7.8 a and b of Technical Specification 3/4.7.8 should be deleted in their entirety M replaced with a

{ resurvey requirement for each benchmark when the current survey reading differs from the previous survey reading by

.more than 1/4 inch.

8. Total Settlement The total settlement of each structure shall not exceed the h predicted values given in Table 1. If the total settlement of any structure reaches the predicted settlement given in

[ Table 1, GPC site engineering should notify GPC corporate engineering for resolution.

I E

C. Differential Settlement Across Structures The differential settlement across structures shall not exceed the allowable values given in Table 2. If the b differential settlement across any structure exceeds 75 percent of the allowable settlement value given in Table 2,

[ GPC site engineering should notify GPC corporate engineering l for resolution.

D. Penetration Differential Settlement Between Structure and Soil The penetration differential settlement between structure and soil shall not exceed the allowable values given in Tables 3 through 6. If the penetration differential

[ settlement between structure and soil exceeds 75 percent of the allowable values given in Tables 3 through 6, GPC site

{ engineering should notify GPC corporate engineering for resolution.

14 F

E E. Penetration Differential Settlement Between Adjacent Structures

[. The penetration differential settlement between structures shall not exceed the allowable values given in Tables 7

{ through 10. If the penetration differential settlement between adjacent structures exceeds 75 percent of the allowable values given in Tables 7 through 10, GPC site engineering should notify GPC corporate engineering for resolution.

Further, it is recommended that provisions be incorporated in

[ the procedure to check the elevations of the reference bench-marks, shown on Figure 17, at least once every 5 years or if it l

{ is suspected that damage to the reference benchmarks has occurred.

[ LIMITING CONDITION FOR OPERATION E

3.7.8 The total settlement of each Class I structure or the differential settlement between or across Class I structures shall not exceed the

[ allowable values of Table 3.7.8-1.

b APPLICABILITY: All CONDITIONS.

ACTION:

r a. With either the total settlement of any structure or the dif-L ferential settlement of any structures exceeding 75% of the allowable settlement value, conduct an engineering review of y field conditions and evaluste the consequences of additional '

L settlement. Submit a special report to the Commission pur-suant to Specification 6.9.2 within 60 days, containing the results of the investigation, the evaluation of existing and possible continued settlement and the remedial action to be taken, if any, including the dr.te of the next survey.

- b. With the total settlement of any structure or the differential L settlement of any structures exceeding the. 11owable settiement value of Table 3.7.8-1, be in at least HOT SHUTDOWN within 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months and in COLD SHUTDOWN within the next 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months .

SURVEILLANCE REQUIREMENTS I

L 4.7.8 The total settlement of each Class I structure or the dif-E ferential settlement between Class I structures listed in Table 3.7.8-1 L shall be determined to the nearest 0.01 foot by measurement and calcula-tion:

a. At least once per 31 days;

~ 1. During the first 6 months of unit operation,

2. Until observed settlement has stabilized,* and rL 3. Whenever previously stabilized

settlement exceeds 0.10 inch since the previous reading.

b. At least once per 6 months.

APPENDIX B

_ SETTLEMENT DATA REACTOR BUILDING UNITS 1 AND 2 NOTES A. GENERAL

1. All reference elevations and survey readings are in feet.

2. All delta (mcVement) values are in inches.

3. For the delta values, + indicates heave and - indicates settle-ment.

4. For each structure, settlement markers and settlement benchmarks E are used interchangably. They are not to be confused with the reference benchmarks used for elevation control, shown on Figure

17. l B. REACTOR BUILDING UNIT 1

1. Assumed a "zero" date for the beginning of settlement monitoring in March 1969.

2. Settlement values for the southwest marker, between December 1969 and July 1970, were estimated from Figure 2A-16, sheet 1 of the Unit 2 FSAR, Amendaient 35, issued in July 1977. No settlement data for the remaining markers were available in this time frame.

3. The settlement values in 1974, for all four markers were estimated from the same figure as in item 2 above.

4. The January 1975 reading for the northwest marker was changed from l 0.079 feet to 0.179 fect. I

5. A settlement marker (benchmark) change was made for the northwest marker in November 1977. It was assumed that no movement of the l I marker occurred between November 1977 and the previous reading, July 1977. An adjustment was then made to the reference elevation to account for the previous movement.

6. New settlement markers (benchmarks) were established in January 1980 for the southwest, southeast and northeast markers. The l referencc elevations were adjusted to account for the previcus E movement.

1 E

E l

l 7. The January 1981 reading for the southwest marker (benchmark) was taken on the "old" marker. The reference elevation was changed to account for this. Subsequent readings use the marker

} established in January 1980.

j C. REACTOR BUILDING UNIT 2

1. Assumed a "zero" date for the beginning of settlement monitoring l in July 1972. This is based on notes appearing on Figure 2A-16, l l sheet 1, of the Unit 2 FSAR, Amendment 35, issued in July 1977. l

2. Original elevations of benchmarks are based on settlement given l on Figure 2A-16A, Sheet 2, Amendment 35, July 1977.

3. A settlement marker (benchmark) change was made for the north-l west marker in October 1977. It was assumed that no movement of the marker occurred since the previous reading. An adjust-ment was made to the reference elevation to account for the previous movement.

4. A settlement marker (benchmark) change was made for the southeast marker in April 1978. It was assumed that no movement of the

} marker occurred between April 1978 and the previous reading, February 1978. An adjustment was then made to the reference ele-vation to account for the previous movement.

5. New settlement markers (benchmarks) were established in January l 1980 for the southwest and northeast markers. The reference elevations were adjusted to account for the previous movement.

E APPENDIX C SETTLEMENT DATA E RADWASTE BUILDING UNITS 1 AND 2 NOTES A. GENERAL

1. All reference elevations and survey readings are in feet.

2. All delta (movement) values are in inches.

3. For the delta values, + indicates heave and - indicates settle-ment.

4. For each structure, settle. ment markers and settlement benchmarks are used interchangably. They are not to be confused with the E reference benchmarks used for elevt. tion control, shown on Figure 17 I E B. RADWASTE BUILDING UNIT 1

1. Assumed a "zero" date for the beginning of settlement monitoring in January 1972. This is based on Figure 2A-16, sheet 2, of the Unit 2 FSAR, Amendment 35, issued in July 1977.

2. New settlement markers (benchmarks) were established in July 1978 for each marker. The reference elevations were adjusted to account for the previous movement.

C. RADWASTE BUILDING UNIT 2

1. Assumed a "zero" date for the beginning of settlement monitoring in October 1975. This is based on Figure 2A-16A, sheet 5, of the Unit 2 FSAR, Amendment 35, issued in July 1977.

2. All survey readings from October 1975 to March 1977 were estimated from figure referenced in item 1 above.

3. For the delta values, + indicates heave and - indicates settle-I 4.

ment.

For each structure, settlement markers and settlement benchmarks I

l are used interchangably. They are not to be confused with the reference benchmarks used for elevation control, shown on Figure

17. l I

[

B. TURBINE BUILDING UNIT 1

1. Assumed a "zero" date for the beginning of settlement monitoring in January 1972.

I j

2. The reported survey reading for the southeast marker in July 1978 was 111.926 feet. Based on previous and subsequent readings this was assumed to be incorrect. Changed survey reading to 111.826 feet.

l

3. New settlement markers (benchmarks) were established in July 1978 for the northwest, northeast and southeast markers. The reference elevations were adjusted to account for the previous movement.

l 4. A new settlement marker (benchmark) was established in June 1979 for the soutnwest marker. However, no readings have been taken due to high radiation.

l C. TURBINE BUILDING UNIT 2

1. New settlement markers (benchmarks) were established in May 1977 I for each marker. It was assumed that no movement of the markers occurred between May 1977 and the previous reading, April 1977.

An adjustment was then made to the reference elevation to account for tne previous movement.

E E 2. A new settlement marker (benchmark) was established in June 1977 for the northeast marker. It was assumed that no movement of 5 the marker took place between June 1977 and the previous reading, May 1977. An adjustment was then made to the reference elevation to account for the previous novement.

3. The northeast marker (benchmark) was destroyed in March 1978. A new marker was established in April 1978. It wa.s assumed that no movement occurred between April 1978 and the previous reading, E February 1978. An adjustment was then made to the reference ele-vation to account for the previous movement.

4. No survey readings have been taken on the northwest marker (bench-5 mark) since January 1979 due to high radiation.

APPENDIX E SETTLEMENT DATA CONTROL BUILDING AND DIESEL GENERATOR BUILDING NOTES A. GENERAL

1. All reference elevations and survey readings are in feet.

. 2. All delta (movement) values are in inches.

3. For the delta values, + indicates heave and - indicates settle-ment.

4. For each structure, settlement markers and settlement benchmarks are used interchangably. They are not to be confused with the reference benchmarks used for elevation control, shown on Figure

17. l B. CONTROL BUILDING

1. Assumed a "zero" date for the beginning of settlement monitoring in January 1972.

2. The settlement values for all four markers (benchmarks) in 1974 were estimated from Figure 2A-16A, sheet 1, of the Unit 2 FSAR, l Amendment 35, i. sued in July 1977.

3. New settlement markers (benchmarks) were established in July 1978 I for each marker. The reference elevations were adjusted to account for the previous movement.

C. DIESEL GENERATOR BUILDING

1. Assumed a "zero" date for the southeast and southwest markers (benchmarks) for the beginning of settlement monitoring in December 1972. This is based on Figure 2A-16A, sheet 3, of the Unit 2 FSAR, Amendment 35, issued in July 1977. No "zero" dates l could be established for the northwest and northeast markers.

2. The settlement values in 1974 for all four markers (benchmarks) were estimated from the above referenced figure in item 1.

1

I l

l

3. New settlement markers (benchmarks) were established for each marker in October 1977. It was assumed that no movement occurred

, between the October 1977 reading and the previous reading, July 1 1977. An adjustment was then made to the referer.ce elevation to account for the previous movement.

APPENDIX F SETTLEMENT DATA INTAKE STRUCTURE AND OFFGAS (MAIN) STACK NOTES A. GENERAL

[ 1. All reference elevations and survey readings are in feet.

2. All delta (movement) values are in inches.

F L 3. For the delta values, + indicates heave and - indicates settle-ment.

4. For each structure, settlement markers and settlement benchmarks -

are used interchangably. They are not to be confused with the -

erence benchmarks used for elevation control, shown on Figure B. INTAKE STRUCTURE

1. Assumed a "zero" date for the beginning of settlement monitoring in July 1972.

2. No survey readings are available between July 1972 and July 1978.

GPC correspondence indicates that the structure settled about

[ 0.1 foot.

3. New settlement markers (benchmarks) were established in July 1978, F for each marker. The reference elevations were adjusted to account L for the estimated previous movement of 0.1 foot.

C. OFFGAS (MAIN) STACK

1. Assumed a "zero" date for the beginning of settlement monitoring in September 1971.

2. Between September 1971 and April 1972 more than one survey reading was taken in certain months. The reported reading here is an average of those readings for a particular month.

3. New settlement markers (benchmarks) were established in January 1973 for each marker. It was assumed that no movement occurred between January 1973 and the previous. reading, July 1972. The reference elevations were adjusted to account for the previous movement. ,

1

E l

l l 4. All settlement values in 1974 for each marker were estimated from Figure 2A-16A, sheet 4, of the Unit 2 FSAR, Amendment 35, issued in July 1977.

l

5. Based on correspondence, it was concluded that the reference elevations for each benchmark were changed in January 1975.

I 6. It was assumed that the February, March and April 1975 survey readings for the south marker (benchmark) were reported incor-I rectly. The readings were changed from 119.891, 119.890 and l 119.891 feet to 119.981, 119.980 and 119.981 feet.

7. A new settlement marker (benchmark) was established for the south l l marker in May 1975. It was assumed that no movement occurred between the May 1979 and the previous reading, April 1975. The reference elevation was adjusted to account for the previous movement.

I

8. It was assumed that the January 1976 survey reading for the south l marker (benchmark) was reported incorrectly. The reading was l changed from 119.997 feet to 119.979 feet.

9. New settlement markers (benchmarks) were established for each l l marker in January 1980. The reference elevations were adjusted I

to account for previous movement.

SETTLEMENT DATA WASTE GAS BUILDING AND LIQUID NITROGEN STORAGE TANK NOTES l A. GENERAL

1. All reference elevations and survey readings are in feet.

I

2. All delta (movement) values are in inches.

l

3. For the delta values, + indicates heave and - indicates settlement.

I l

4. For each structure, settlement markers and settlement benchmarks are used interchangeably. They are not to be confused with the reference benchmarks used for elevation control, shown on Figure 17.

B. WASTE GAS BUILDING l

1. An assumed "zero" date for the beginning of settlement monitoring I is not known. The first recorded settlement readings were in January 1973.

I l

2. New settlement markers (benchmarks) were established in September 1973 for all markers. It was assumed that no movement took place between September 1973 and the previous reading, August 1973. An adjustment was then made to the reference elevation of each marker to account for the previous movement.

l

3. New settlement markers (benchmarks) were established in July 1974; however, no settlement readings were available until January 1975.

L

4. New settlement markers (benchmarks) were established in October 1977 for all markers. It was assumed that no movement took place between October 1977 and the previous reading, July 1977.

An adjustment was then made to the reference elevation of each marker to account for the previous movement.

F 5. New settlement markers (benchmarks) were established in January 1980 for all markers. An adjustment was then made to the reference elevation of each marker to account for the previous l movement.

C. LIQUID NITROGEN STORAGE TANK

1. Assumed a "zero" date for the beginning of settlement monitoring in June 1978.
