February 4, 1986 N Qg 1.0 CONTRACTOR-FURNISHED INSTRUMENTATION 1.1 A Fluke Model 2240 data logger is used to scan all data channels, provide a hard copy of all raw data, and perform an analog-to-digital conversion of the voltage outpu'ts .from each DCDT. The data logger scans at three readings per second, and has a range of +40 ,
volts with 1 my resolution.
1.2 Trans-Tek direct current dif ferential transducers (OCDT's) are displacement transducers providing a DC voltage output proportional to
, displacement. The working range of the instrument is 2.00 inches with a total mechanical travel of 2.25 inches. The input voltage range is three to 30 volts. The resolution is infinite and the linearity percent full scale over the total working range is within 10.5L 1.3 For deflection measurements greater than 2.00 inches (shell diameter displacements), a specially-designed taut wire bracket will be used. This bracket will allow a total of 3.00 inches of deflection to be measured.
- he calibration of the OCOT (see next section) provides a scale
- - (in units of inches per volt) which allows the conversion of ru soltage data to engineering units. The calibration procedure also allows a check of DCDT linearity.
1.5 A Hewlett-Packard Model 85 microcomputer accepts digitized data from the Fluke data logger. These data are then converted to engineering units by applying the unique scale factor for each DCOT to
l ATTACHMENT 902 1-PT(I)-36 REv. 1 Page 5 fednical Report WM TR-20422(836) February 4, 1986
. tne f ata. Also, the sign of the OCOT signal change indicates the l s
direction of deflection. The accuracy and range of these data are I determined by the Fluke data logger.
1.6 After processing, the Model 85 computer provides a printout of the deflection measurement data and stores the data on floppy disc.
1.7 The Hewlett-packard Model 82901M disc drive accepts the raw and processed data from the Model 85 computer.
1.8 A Hewlett-packard Model 829058 printer is used to provide a hard copy of the processed data.
1.9 In addition to the data acquisition equipment, BEL /TES will supply a calibration apparatus for the OCOT's. This apparatus consists of a calibrated Starrett No. 63 micrometer head having a
+1.000 inch range and a resolution of 0.001 inch, a BEL /TES designed and built fixture, a Doric Model 05-100 voltmeter, and a Hewlett-Packard Model 6220B power supply (0 60 volt range).
- 1. *. ' Taut Wire Apparatus: The taut wire apparatus maintains a c :at tension on the Invar wire at all times independent of ce- 2:: ton. For this reason, sag which may exist in the wire will not have an ef fect on the deflection measurement. The pivot arm moves on i
a 1/4-inch inside diameter bearing which provides a very small pivot radius and introduces no significant friction. No temperature compensation is required because of the thermal properties of the Invar wire. The only calibration required is the OCOT calibration.

February 4, 1986 6 gg 2.0 'OATA ACQUISITION AND RETRIEVAL SYSTEM 2.1 The system used to acquire the data is comprised of the OCOT's used to sense the actual deflection; cabling to the instrument setup; a Fluke Model 2240 data logger; a Hewlett-Packard Model 85 microcomputer; a Hewlett-Packard Model 82901M disc drive; and a Hewlett.Packard Model 82905B printer. See Figure 1.
2.2 The data acquisition system is monitored on a daily basis for several days prior to the start of the structural integrity test in order to demonstrate the reliability and function of the system. Any instabilities in the system will be corrected during this period.
2.3 When testing is about to begin, a baseline will be established for all instrument locations. This baseline scan is made prior to any pressurization and represents the zero deflection point. This baseline will be subtracted from each subsequent scan, thereby allowing a determination of the actual deflection of the containment structure.
2.1 " 4 ring the calibration of the DCOT's, a calibration factor is ce . - aed based on fitting the calibration data to the best straight l'ae :assing through zero. This calibration factor has units of inches per volt, allowing the result of multiplying the scale factor by the input voltage to have units of inches. This calculation is carried out in the computer as the data are being acquired. This
( allows a nearly real time output of deflections in proper units.

' 2. : No other calibration of the data acquisition System is required; however, another system check is performed by placing a block of known size between the DCDT plunger and the surface on which it impinges.
This deflection is then read out on the data acquisition system and compared for acceptable accuracy with the known dimension of the gage block. This system check is performed on a random basis for approximately 10% of the installed DCDT's.
2.6 A hard copy of raw data is produced by the data logger during each scan. A total of three scans are averaged by the computer for each pressure level. Each subsequent scan is compared with the previous scan and automatically checked for scatter of the data. This procedure ensures that a brief vibration or hanging up of a DCOT for mechanical reasons is not recorded as data. Inconsistencies in subsequent scans would flag the operator to ccrrect the problem and repeat the measurement.

10.0 CONDUCTANCE OF THE STRUCTURAL INTEGRITY TEST 10.1 The Senior Test Engineer will ensure that all preparations have been completed prior to the start of the SIT. A checklist will be prepared to indicate the readiness of the work for start of test.
Prior to the actual test, all instrumentation will be monitored to ensure stability. Last-minute walkdowns of all measurement locations and crack mapping areas will be made as necessary to ensure no damage or mal function has occurred since the initial installations were made.
10.2 Before pressurization of the containment building begins, a ,
baseline data scan will be made. This data scan will serve as a reference for. subsequent data scans.
10.3 All subsequent data scans will be conducted one hour after each pressurization and depressurization plateau has been reached at the direction of the Test Director. All crack mapping charts will be collected. Data Recording Sheets (as in Appendix A of Specification 9763.006-5-5) will be completed and date, time, pressure, temperature vd ~.midity data will be recorded as they are provided. A computer
- - - .: of deflection data will be provided for evaluation. After a :::a are recorded and evaluated, the Senior Test Engineer and Quality Assurance Inspector will sign off the check list held by the Test Director. Photographs of crack mapping areas may be made after sign-off has occurred.

10.2 A final data scan will be made just prior to the end of the 24-hour recovery period at the direction of the Test Director.
10.5 Following the 24-hour stabilization period, all instruments will be checked and DCDT's recalibrated, and any difference or adjustments required will be noted. The Senior Test Engineer will complete the Instrument Recovery Data Form at this time.
10.6 A documentation package consisting of data acquisition system printouts, ccmplete data recording sheets, crack mapping charts, and event log will be provided by BEL /TES before leaving the site.
10.7 A Certificate of Conformance for field work will also be provided by BEL /TES.

"11.0 PROCESSING OF RAW DATA 11.1 The raw data have units of voltage. To convert these data to units of inches, a scale factor is applied to each data reading.
These scale factors (one for each DCDT) have units of inches per volt.
When raw data (voltage) are multiplied by the scale factor (inches per volt), the result has units of inches. These scale factors are obtained during the calibration of each DCDT when a deflection-versus-voltage output set of data is obtained. The scale factors are the result of finding the best fit for these data to a straight line, and then using the slope of this line as the scale factor.
f 11.2 To obtain vertical deflections wi. thin the dome of the containment structure from the nonvertical deflection measurements being recorded there, it is necessary to apply simple trigonometry.
The initial height from the spring line to each of the dome measurement points can be calculated based on known elevations. The change in height during testing will be determined as follows: the taut wires suspended across the dome form a series of triangles. The
+- Mhs of all sides and angles of these triangles can be solved
' illy and their heights (distance from measurement point to spring e) cal cul ated. 'The lengths of the sides of these triangles are being measured by the taut wire devices. The new lengths are the sum of the original lengths and the change in length measured by the DCDT.
Using the Law of Cosines, new angles can be calculated based on these
( lengths. The length of a perpendicular dropped from the apex of each
