,..;, 0 Objective This analysis will document loop accuracy calculation for various temperature indicating loops. These temperature loops are for PCS temperature, and calculations will provide normal accuracies, as well as accuracies during various postulated accident scenarios (large break LOCA, small break LOCA, MSLB inside containment, MSLB outside containment). See Attachment 1 for a list of the loops for which calculations will be *performed.

Background

. All of the temperature elements listed in Attachment 1 are located in containment. The temperature trans-mitters, indicators, and recorders are located in the control room. Analysis This analysis will first describe the individual components and their accuracies. It will then show the three different configurations that the components are used in. It will finally calculate the total loop accuracy using the root-sum square method for each of the three distinct loops. The temperature. elements (TE) are the only portion of the loop that will be affected by any of the accident scenario. The TE is a Rosemount Model 104AJBO and is EEQ qualified. The TE was qualified by National Technical Systems Report 558-1711. A sunmary of that report is provided in EA-P-EEQ-86-30. Both the test report and sunmary _are in Vendor File M-10, Sh 1. As stated in the summary of the test report, the TE error was negligible and was not affected by the test environment. The TE accuracy of +/-.161, as COl'IPared to -that of error of other components in the loop, is considered insignificant and will be ignored for the calculation.

  • The *transmitt~rs (TT) are Rochester instrument Model SC-1373-323 dual-range. They are used at low range for 515°F to 615°F and at high range for 50°F to 700°F measurements. These transmitters were recently installed during modification FC-567 *core Cooling Instrumentation.* The. I&C Department calibrated the
  • transmitters to +/- 1.51 (9.75°F) for the wide range (TTWR). and.51 (.5°F) for the narrow range (TTNR) as shown on the calibration sheet, attached.

The temperature indicators (TI) are Sigma Model 9223-E-OO. They are used for the low range of the trans-

  • mitters and read 515°F'to 615°F~ From the data sheet on M-801, page 9 and the I&C calibration sheet (attached).it is shown that the accuracy is+/-.5°F. This-indicator is divided into 2°F divisions. Using the standard readability of+/- 1/2 division, the readability would be+/- 1°F.

The pressure-temperature recorders (PTR) are Westronics Model T4N. They are used with the wide range output of the temperature transmitter (TT). They record frQlll 50°F. to 700°F. Per the attached I&C calibration sheet they are accurate to+/- l0°F. The PTR has no additional readability error. The subcooling margin monitor (SMM) monitors both pressure and temperature. As stated in Technical Speci-fication Surveillance Procedure RI-69, the SMM has an error of +/- l.2°F. The SMM is digital and has no read-ability error. The temperature signal isolator (I/I) is a Deval Model 18-119. It is used with a wide range temperature transmitter (TTWR) to provide a signal to the Subcooling Margin Monitor (SMM). The l & C department calibrates the I/I to+/-.5% (3.25°F) as shown on the attached calibration sheet

.,;. c.J The following table su11111arizes the accuracies of various components used in this analysis.

TE =.161 - Negligible (will not be used) TTNR = +/-.5°F TTWR = +/- 9.75°F TI = +/-.5°F SMM = +/- l.2°F PTR = +/- 10°F TIR = Temperature Indicator Readability +/- 1°F I/I = +/- 3.2.5°F Three distinct PCS temperature loops exist for which calculation will be performed. The first loop consists_ of a temperature element (TE), a narrow range temperature transmitter (TTNR) and a temperature indicator (TI). These loops are shown as Items 1-9, 12, 15, 17, 19, 21, 23, and 26 on Attachment 1. The second loop consists of the temperature element (TE), a wide range temperature transmitter (TTWR) and a pressure temper-ature recorder (PTR). These loops are shown as Items 10, 13, 24, and 27 on Attachment 1. The third loop consists of the temperature element (TE), a wide range temperature transmitter (TTWR), a signal isolator* (I/I) and the subcooling margin monitor (SMM). These are shown as Items 11, 14, 16, 18, 20, 22, 25, and 28 on Attachment 1.

  • The root-sum square method will be used to calculate the loop error. As stated earlier, the TE accuracy is negligible and the PTR and SMM have no readability error. Each calculation will provide the formula to be used, then the actual calculation.
