I 1.0 GENERAL A basic design criteria for all Categol.7 I structures, with the exception of the Service Water Pump House (SWPH), for Units 3 and 4 of the North Anna Power Station is that the structures be I founded on rock, or on caissons socketed into rock, to absolutely minimize settlements. Therefore, structure settlements can be anticipated to be negligible. At ha direction of the Nuclear Regulatory Commission, a two-star "ste settlement monitoring proaram will be developed for Unie 5 and 4. The first stage (construction settlement I monitoring program) will begin after the construction of the foundation mats. The second stage (permanent settlement monitoring program) will be initiated as certain critical safety-I related pipes and/or duct line connections are completed. The objectives of the site settlement monitoring program are the following: 1. To provide a record of settlement versus time 2. To establish a technical specification for allowable settlement for all structures supporting safety-related piping and duct lines I 3. To provide data necessary to evaluate the performance of structures relative to the referenced technical specification The purpose of this report is to describe the scope of the construction settlement monitoring program and to provide the information requested ia the October 6, 1978, letter from the I Nuclear Regulatory Commission. The permanent settlement monitoring program will be described at a later time. I

2. O SETTLEMENT MONITORING POINTS 2.1 Location All major plant structures whether category I or not will be monitored during the construction settlement monitoring program.

A site plot plan is shown in I Figure 1. Proposed locations of the settlement monitoring points are shown in Figures 2 through 25. A summary of the locations and designation of the settlement monitoring points is given in Table I. Settlement monitoring point locations have been chosen to provide a complete documentation of structure I settlement and allow accurate determination of differential settlement between structures. The settlement monitoring point locations as shown in I Figures 2 through 25 are the anticipated locations for the proposed points. Certain construction situations or interferences may dictate that some of the monitoring point locations be altered and that the points be I I

I I installed at locations other than those shown in the figures. 2.2 Design and Installation I settlement monitoring points will consist of brass disks embedded in the concrete foundations, except as described in Section 8.0 for the SWPH. These points I will be installed either during concrete placement of future foundations, or by chipping or coring the concrete in existing foundations, and then grouting the disks in place. The brass disks will be recessed below I the top of the concrete and will be protected from damage during construction by a steel pipe coupling fitted with a countersunk pipe plug. A sketch of a I typical settlement monitoring point is shown in Figure 26. 3.0 PERMANENT REFERENCE MONUMENTS I 3.1 Location Two oermanent reference monuments will be installed near the Units 3 and 4 construction area. Surveys for the monitoring program will be referenced ' the monuments. I The locations of the permanent reference monuments are shown on Figure 27. 3.2 Design and Installation The permanent reference monuments consist of concrete filled pipes socketed in rock. A typical section of a reference monument is shown in Piqure 28. A series of " bumper guards," placed around each reference

monument, is designed to provide protection from damage resulting from possible impact.

4.0 RECORDED DATA The initial data to be recorded with the installation of each settlement monitoring point are the following: I 1. Se ttlement monitoring point identification number (see Table I) 2. Elevation establishing the initial vertical location of I the settlement monitoring point, as shown on Figure 29. I I I

I 3 I

5. 0 FREQUENCY OF SURVEY DATA The initial elevation of each settlement monitoring point will be recorded a f ter its installati on.

Subsequently, surveys will be made at a standard free" y of at least once every six months (plus or minus six weeks) ror all structures. The frequency of the existing settlement monitoring program for the partially completed SWPH is discussed in Section 8.0. 6.0 . SUBMITTAL OF DATA The data obtained during the construction settlement monitoring program for all Category I structures will be submitted annually. Changes in

location, or additions to the initial settlement mor itoring points, will be submitted with the annual reports.

As construction proceeds, the construction settlement monitoring program will g radually phase into the permanent settlement I monitoring prog ra m. The beginning of the permanent settlement monitoring program will be noted in the annual reports as the transition occurs for each structure. 7.0 TECHNICAL SPECIFICATION FOR ALLOWABLE SETTLEMENTS I It is presently envisioned that the technical specification for allowable settlements will be in a form similar to Table II. These specifications will define limiting values of differential settlement that can be accommodated b, the critical safety-I related item. The actual limiting value for any given safety-related item will be determined later. Differential settlements between structures connected by a sa fety-related item are of I significance only after structure-to-structure connections are made. The re f o re, allowable settlements of structures are applicable only after the connections are completed. A list of safety-related items is given in Table III. During the course of determining the settlement techaical specifications, the most critical system (least capacity to accommodate I dif ferential settlement) between any two structures will be determined and noted with future annual reports. Hence, it is anticipated that the list in Table III will be reduced significantly with future submittals. The final version of the technical specifications for allowable settlements will be submitted at a future time compatible with I the Staff's review of all technical specifications. 8.0 EXISTING SETTLEMENT MONITORING PROGRAM I Settlement monitoring of the Service Water Pump House (SWPH) was initiated before the development of the construction settlement monitoring prog ram. Well-defined scribe marks in the exterior I

4 wall, at the location shown in Figure 19, have been and will continue to be used for settlement monitoring of the SWPH. The two existing reference monuments installed near the Service Water Reservoir have been used for survey control for settlement monitoring of the SWPH. Future surveys of the SWPH for the construction settlement monitoring program will be referenced to these monuments. The settlement data previously obtained from this structure will be incorporated into the construction settlement monitoring program. Settlement monitoring of the SWPH was initiated immediately after tne foundation mat was constructed in December 1974. The frequency of surveys has varied during the interim period to date. Surveys for the construction settlement monitoring program will be taken on a monthly basis when construction of the SWPH resumes. The frequency of surveys will be converted to the standard frequency when evaluation of settlement data indicates that settlement of the SWPH has stabilized.

SUMMARY

The construction settlement monitoring program will establish a lan for the location, installation, survey, and evaluation of settlement monitoring points embedded in the foundations of the plant structures. The locations of the settlement monitoring points will be indicated on construction drawings. The settlement monitoring points will be installed in sleeves set beJow the top of concrete. This arrangement will minimize damage to the points and ensure continued survey readings of the settlement monitoring points. Periodic surveys will be made and re corded for each structure. The construction settlement monitoring prog ram will develop settlement versus time for the Units 3 and 4 structures. The construction monitoring program will gradually phase into the permanent monitoring program. The transition to the permanent monitoring program will occur at the final connection of safety-related pipe and/or duct line installations. The program herein described is envisioned as meeting the requirements for settlement monitoring during construction of Units 3 and 4. The program will be altered, changed, or modified when necessary to enhance the data oi data collection effort. 4 4 4

E p Indicates location of settlement monitoring point ). 2. Coordinates are plant coordinares. 3. Settlement monitoring points are located 2 ft from adjacent walls, unless noted on figures. 4. Actual locations of settlement monitoring points will be adjusted slightly to avoid any interference with rebar and/or baseplates. I 5. Foundation construction has been partially completed, as of the date of this report, on the following structur,_: Reactor containment - Units 3 and 4 (mat) Auxiliary building (mat) Intake structure (mat) Service water pump house (mat and walls up to el 326 f t) Intake tunnels Discharge tunnels 6. Existing settlement monitoring points are located on the roof of the soil-founded tunnel sections. Additional points shall be placed on the roof, as shown in Figures _1_7 and 18, on all completed rock-founded tunnel sections. When construction resumes on both soil-and rock-founded tunnel sections, the construction monitoring program will include additional settlement monitoring points on the mats as shown in Figures 16, 17, and 18.
