NRC Administrative Letter 98-10, "Dispositioning of Technical Specifications that are Insufficient to Assure Plant Safety" dated December 29, 1989

Dear Sir or Madam:

In accordance with the provisions of Section 50.90 of Title 10 of the Code of Federal Regulations (10 CFR), Entergy Operations, Inc. is submitting a request for an amendment to the Technical Specifications (TS) for Grand Gulf Nuclear Station, Unit 1 (GGNS). The proposed amendment would revise the TS to support correction of five non-conservative technical specification allowable values. The revision to the calculations did not result in setpoint changes, only the allowable values are required to be changed. Therefore, the functionality of the associated equipment is not in question since the actual plant setpoints are currently conservative with respect to the analytical limits.

Attachment 1 provides an evaluation of the proposed changes.

Attachment 2 provides the markup pages of existing TS to show the proposed changes.

Attachment 3 provides revised (clean) TS pages.

SUMMARY

DESCRIPTION This letter is a request to the Nuclear Regulatory Commission (NRC) to amend Facility Operating License NPF-29 for the Grand Gulf Nuclear Station (GGNS). The requested change affects the Allowable Values listed in section 2.1 below. This request is submitted pursuant to 10 CFR 50.90 to correct a non-conservative TS and, consistent with the guidance of NRC Administrative Letter (AL) 98-10, "Dispositioning of Technical Specifications that are Insufficient to Assure Plant Safety", dated December 29, 1998 (reference 6.1).

As demonstrated in this submittal, the proposed changes do not adversely impact safety and is required by NRC AL 98-10. Entergy Operations, Inc. requests approval of the proposed license amendment by March 14, 2015. Once approved, Entergy will implement the amendment within 90 days.

2.0 DETAILED DESCRIPTION 2.1 Proposed Changes Revisions of setpoint Calculations listed below identified that five associated technical specification allowable values were non-conservative. The current setpoints remain conservative. The non-conservative allowable values are required to be revised in accordance with NRC Administrative Letter 98-10.

The upper allowable values for these functions do not need to be changed.

2.2 Need for Changes The discovery of non-conservative allowable values requires changes to the technical specifications. The changes are required to ensure that the TS is sufficient to assure nuclear safety.

GNRO-2014/00014 Page 2 of 6 2.3 TSTF-493 Considerations GGNS is aware of the NRC position to encourage Technical Specification Task Force (TSTF)-493 (Reference 6.3) adoption by requiring licensees to provide a determination for each instrumentation function proposed for revision, as to whether the function is a Limiting Safety System Setting (LSSS) that protects a safety limit.

Attachment A to TSTF-493, Revision 4, entitled "Identification of Functions to be Annotated with TSTF-493 Footnotes," identifies those functions that are LSSS.

Based on the Attachment A listing for NUREG-1434, "Boiling Water Reactor/6 Plants", none of the functions associated with the proposed technical specification changes require TSTF-493 Footnotes.

3.0 TECHNICAL EVALUATION

3.1 Inspection Manual Chapter (IMC) 0326 In NRC IMC 0326 (reference 6.2) and NRC AL 98-10 (reference 6.1), the NRC provided guidance for prompt corrective action to correct or resolve a degraded or non-conforming condition. In the case of non-conservative TS, this includes the evaluation of compensatory measures, such as administrative controls, in accordance with 10 CFR 50.59 and prompt actions to correct the TS. This section provides a description of the methodology used by Entergy to complete the evaluation for the requested TS allowable value change.

GGNS utilizes the methodology documente~ in JS-09 Rev. 1 "Methodology for the Generation of Instrument Loop Uncertainty & Setpoint Calculations." (reference 6.5) to calculate loop uncertainties and setpoints. This methodology is used coincident with the GE instrument setpoint methodology published in NEDC-31336. This method includes using the available uncertainty data along with the following general steps to generate an appropriate loop Allowable Value and Nominal Trip Setpoint.

Calculate the Loop Uncertainty (LU) by computing the SRSS of the Loop Device Uncertainty (Ad, the Loop Calibration Uncertainty (Cd, the Process Measurement Uncertainty (PM), and the Primary Element Uncertainty (PE).

Calculate the Loop Drift (Dd by computing the SRSS of the Device Drift (DR), the Temperature Drift (TO), and the Radiation Drift (RD) for each loop instrument as applicable.

Calculate the Total Loop Uncertainty (TLU) by combining the Loop Uncertainty, the Loop Drift and any applicable biases.

For process variables that increase to the Analytical Limit (AL), calculate the loop Allowable Value (AV) by subtracting the Loop Uncertainty from the Analytical Limit. For process variables that decrease to the Analytical Limit, calculate the loop Allowable Value by summing the value of the Loop Uncertainty and the Analytical Limit.

For process variables that increase to the Analytical Limit (AL), calculate the loop Nominal Trip Setpoint (NTSP) by subtracting the value of the Total Loop Uncertainty from the Analytical Limit. For process variables that decrease to the Analytical Limit, calculate the loop Nominal Trip Setpoint (NTSP) by summing the value of the Total Loop Uncertainty and the Analytical Limit.

GNRO-2014/00014 Page 3 of 6 The Calculations listed in section 2.1 determine the instrument loop uncertainty, limiting allowable values and setpoints. The revision to the calculations did not result in setpoint changes, only the allowable values are required to be changed. The functionality of the associated equipment is not in question since the actual plant setpoints are currently conservative with respect to the analytical limits. Therefore, the instrumentation can perform its specified TS safety function.

The TRM trip setpoints are not changed; therefore the systems remain capable of performing specified safety functions in accordance with applicable design requirements and associated analyses. Since the systems remain capable of performing specified safety function, no compensatory measures are required. This license application request (LAR) is submitted to request permission to revise the technical specifications to eliminate the non-conservative allowable values.

4.0 REGULATORY SAFETY ANALYSIS NRC AL 98-10 provides generic guidance to licensees on the type and time frame of any required corrective action for resolution of degraded and nonconforming conditions. As stated in the GL, whenever degraded or nonconforming conditions are discovered, 10 CFR Part 50, Appendix B, requires prompt corrective action to correct or resolve the condition. In the case of a deficient TS, this includes the evaluation of compensatory measures, such as administrative controls, in accordance with 10 CFR 50.59 and prompt actions to correct the TS. This request for license amendment provides the GGNS-specific actions to resolve the degraded or nonconforming condition. GGNS has determined that the proposed changes do not require any exemptions or relief from regulatory requirements, other than the TS, and do not affect conformance with any draft General Design Criteria differently than described in the GGNS UFSAR, as described below.

4.1 Applicable Regulatory Requirements/Criteria Regulatory requirement 10 CFR 50.36, "Technical Specifications," provides the content required in a licensee's TS. Specifically, 10 CFR 50.36(c)(3) requires that the TS include surveillance requirements. The proposed TS allowable value (AV) change continues to support the requirements of 10 CFR 50.36(c)(3) to assure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the limiting conditions for operation are met.

The calculations listed in section 2.1 determine the instrument loop uncertainty, limiting allowable values and setpoints for TS instrument loops. The revisions to the calculations did not result in setpoint changes; only the allowable values were required to be changed.

This request for license amendment provides the GGNS specific calculation used to determine the setpoint and allowable value evaluation and provides a description of the methodology used by GGNS to complete the evaluation for the specific TS SR being revised.

In conclusion, based on the considerations discussed above, (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.

GNRO-2014/00014 Page 4 of 6 4.2 No Significant Hazards Consideration 10 CFR 50.91 (a)(1) requires that licensee requests for operating license amendments be accompanied by an evaluation of no significant hazard posed by issuance of the amendment. Entergy has evaluated this proposed amendment with respect to the criteria given in 10 CFR 50.92(c). The following is the evaluation required by 10 CFR 50.91 (a)(1).

Entergy is requesting an amendment of the Operating License for the Grand Gulf Nuclear Station (GGNS) to revise the Technical Specification (TS) Allowable Values (AVs) listed in section 2.1.

Entergy has evaluated whether or not a significant hazards consideration is involved with the proposed amendment by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of amendment," as discussed below:

1. Does the proposed change involve a significant increase in the probability or consequences of an accident previously evaluated?

Response: No.

The proposed TS allowable value changes involve changes in the margin between the allowable values and the setpoints. The proposed TS changes do not change the trip setpoints. The proposed TS changes do not degrade ,the performance of, or increase the challenges to, any safety systems assumed to function in the accident analysis. The proposed TS changes do not impact the usefulness of the SRs in evaluating the operability of required systems and components, or the way in which the surveillances are performed. In addition, the the trip setpoints for the associated TRM functions are not considered an initiator of any analyzed accident, nor does a revision to the allowable value introduce any accident initiators. Therefore, the proposed change does not involve a significant increase in the probability of an accident previously evaluated.

The consequences of a previously evaluated accident are not significantly increased. The proposed change does not affect the performance of any equipment credited to mitigate the radiological consequences of an accident.

Evaluation of the proposed TS changes demonstrated that the availability of credited equipment is not significantly affected because of the reduction in margin between the allowable values and the trip setpoints.

Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.

2. Does the proposed change create the possibility of a new or different kind of accident from any accident previously evaluated?

Response: No.

The proposed TS changes involves changes in allowable value settings to correct non~conservative values. The proposed TS changes do not introduce

GNRO-2014/00014 Page 5 of 6 any failure mechanisms of a different type than those previously evaluated, since there are no physical changes being made to the facility.

No new or different equipment is being installed. No installed equipment is being operated in a different manner. As a result, no new failure modes are being introduced. The way surveillance tests are performed remains unchanged.

Therefore, the proposed change does not create the possibility of a new or different kind of accident from any previously evaluated.

3. Do the proposed changes involve a significant reduction in a margin of safety?

Response: No.

The proposed TS change involves changes in the allowable value settings to correct non-conservative values. The impact of the change on system availability is not significant, based on the frequency of the testing being unchanged, the existence of redundant systems and equipment, and overall system reliability. The proposed change does not significantly impact the condition or performance of structures, systems, and components relied upon for accident mitigation. The proposed change does not result in any hardware changes or in any changes to the analytical limits assumed in accident analyses. Existing operating margin between plant conditions and actual plant setpoints is not significantly reduced due to these changes. The proposed change does not impact any safety analysis assumptions or results.

Therefore, the proposed change does not involve a significant reduction in a margin of safety.

Based on the responses to the above questions, GGNS concludes that the proposed amendment with respect to the TS AV change presents no significant hazards consideration under the standards set forth in 10 CFR 50.92(c) and, accordingly, a finding of "no significant hazards consideration" is justified.

4.3 Conclusion In conclusion, based on the considerations discussed above, (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commissions regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.

5.0 ENVIRONMENTAL CONSIDERATION

The.proposed changes would change requirements with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR 20, and would change inspection or surveillance requirements. However, the proposed changes do not involve (i) a significant hazards consideration, (ii) a significant change in the types or significant increase in the amounts of any effluent that may be released offsite, or (iii) a

GNRO-2014/00014 Page 6 of 6 significant increase in individual or cumulative occupational radiation exposure.

Accordingly, the proposed change meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(9). Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed changes.

CALCULATION NO._....::..JC:::::..-...::oQ;"..;:;.I=B=-21::--=K;.;:;,..II~4:..-- REV. 002 1.0 PURPOSE The purpose of this calculation is to detennine the instrument loop uncertainty, limiting allowable values and set points for instrument loops IB21CKI14A,B,E,F and IB21CK005A,B. The values generated by this c~lculation are in accordance with reference 3.1.1.

2.0 DESIGN REQUIREMENTS Safety/relief valves used for automatic depressurization (ADS) under assumed loss-of-coolant accident conditions shall automatically open and remain open below their preset closing pressure. The open signal is based on signals from both high drywell pressure and low reactor water level and confinnation of one low pressure core spray or low pressure core injection running. (Ref. 3.1.3) Initiation of signals does not need to be simultaneous.

By remaining open, the relief valves shall reduce reactor pressure to the point where the residual heat removal (LPCI mode) and/or the low pressure core spray systems can adequately cool the core.

Initiation of ADS is delayed a nominal 105 seconds (Timers IB21C-K5A,B) to allow the operator to tenninate ADS action if HPCS initiation and acceptable reactor level have been confinned (Ref. 3.1.3).

For events which result in low RPV water level, but do not pressurize the drywell, the ADS initiation signal is delayed by.the drywell bypass timers 1B21 CKI14A,B,E,F for a nominal 9 minute delay. If low water level persists when the bypass timer has timed out, the ADS timers, IB21CK005A or B is activated as before. (Ref. 3.1.3)

Adequate LPCI or LPCS pump discharge pressure to assure a low pressure ECCS pump is running and capable of delivering water to the vessel is a pennissive for ADS initiation.

(Ref. 3.2.1, p7.3-9)

The initiating event for ADS is a LOCA involving an RCPB breach either inside or outside the drywell. This could subject the equipment in containment to accident conditions. However the timers addressed by this calculation are located in panels in the control room where the accident environment is the same as nonnal (Sections 4.2 & 4.3).

Therefore, the timers will be required to function under nonnal environmental conditions.

The ADS System is part of the Nuclear Boiler System and is required to meet seismic category I requirements (SSE) (Ref. 3.1.4). Therefore the timers must function during and after a seismic event.

For instrument loops IB21CKI14A,B,E,F the analytical limit (AL) is 10 minutes (Ref.

3.1.19), the Technical Specification allowable value (AV) is::; 9.4 minutes (Ref. 3.2.2) and the TRM setpoint is ::; 9.2 minutes (Ref. 3.2.2).

5.0 ASSUMPTIONS 5.1 The Reference Accuracy includes repeatability. It can be seen below and in section 4.0 of this calculation that TE, HE, RE and PS can be included in the repeatability ~ince the nonnal operating conditions for the timer relays approximate the nonnal operating conditions of the plant and the conditions under which the loops must function.

The Temperature Effect (TE) can be considered zero since the operating range of the timers (FTR: 40°F - 156°F, ETR: 40°F - 145°F encompasses the DBE temperature range (69°F - 90°F) in the rooms where the timers are located.

The Humidity Effect (HE) is not applicable to these timers since the timers can maintain their accuracy within the range of the room environment where they are located.

FTR Range: 40-90% RH ETR Range: 20-50% RH Room environment DBE humidity: 50% RH The Radiation Effect (RE) does not affect the accuracy of the timers since their room environment will not exceed a total integrated dose (TID) of 1.8E2 Rads and the timers can maintain their accuracy up to 1.75E5 Rads for the FTRs and 1.8E5 Rads TID for the ETRs.

The minimum coil pickup voltage for the FTR timer relays is 94 VDC and for the ETR timer relays is 100 VDC. The nonnal operating range of the 125 VDC DIY I and DIY II battery bus is maintained between 105 VDC and 140 VDC (UFSAR section 8.3.2.1.6.2, reference 3.2.4). Since the lowest voltage that will be present on the bus is 105 VDC, and the timers coils can actuate at a voltage lower than this, the power supply effects (PS) will not hinder the repeatability of the timers.

The Static Pressure Effects (SPE) do not apply to the timers since this effect is a relationship between a high and low sensing port at a static pressure usually on differential pressure units.

5.2 Relay IB21K005A is a model number TR14D3EC750, which is assumed to be identical to FTR14D3EC750 in all aspects important to this calculation (Ref.

3.1.6).

5.3 Vendor documents list equipment perfonnance data without stating the statistical basis for the numbers. Although some vendor data is "worst case" it will be assumed that all such data is a 2 sigma value.

5.4 Per reference 3.1.1, the M&TE error is nonnally assumed to be equal to the reference accuracy of the sensor. Per reference 3.1.17, for the K005A,B relays the

test equipment used to determine the setpoint has an accuracy of"+/- 0.5 seconds.

Per reference 3.1.17, the actual trip setpoint can adjusted between 100 and 105 seconds. For this calculation we will assume the technician sets the time delay relay at the center of this band, which results in a setpoint tolerance of +/- 2.5 seconds. Therefore, for the K005A,B relays the conservative actual setting tolerance, +/- 2.5 seconds, will be used as input for the M&TE error.

Per reference 3.1.17, for the KII4A,B,E,F relays the test equipment used to determine the setpoint has an accuracy of +/- 0.5 seconds. The actual setting tolerance is +/- 14.0 seconds ((552-524)/2), per reference 3.1.17. Converting to minutes the result is +/-0.24 minutes. Therefore, for the KII4A,B,E,F relays the conservative actual setting tolerance of +/- 0.24 minutes will be used as input for the M&TE error.

5.5 No data regarding the Amerace/Agastat model FTR timer relay used for IB2ICK005A & B was available from the vendor. However there is historical calibration data available on drift. This data was used to calculate the drift based on the calibration interval. The drift analysis resulted in value of +/-2.28 seconds (Appendix 2). The drift values are for a three month period.

5.6 No data regarding the Amerace/Agastat model ETR timer relay used for IB2ICKII4A,B,E,F was available from the vendor. However there is historical calibration data available on drift. This data was used to calculate the drift based on the calibration interval. The drift analysis resulted in value of +/-5.38 seconds (Appendix 1). The drift values are for a three month period.

5.7 The timer relays are seismically qualified devices. Since the vendor does not identify any seismic effect error for the timer relays it is assumed that any seismic effects are included in the reference accuracy.

Appendix 1 1821-K114A,8,E,F Drift Analysis 1.0 Purpose The purpose of this document is to calculate the drift uncertainty value to be used for the 1B21-K114A, B, E and F ADS Bypass Timer relays. The River Bend and Grand Gulf Nuclear Station Instrument Drift Analysis Guide (RBS/GGNS-002, Rev. 0), Reference 2.1, was utilized to determine the drift uncertainty value for these relays.

2.0 References 2.1 ECH-NE-08-00015, Rev. 1 , River Bend and Grand Gulf Nuclear Station Instrument Drift Analysis Design Guide 2.2 06-EL-1 B21-0-0001 , Rev. 101. Surveillance Procedure ADS Timers Functional Test and Calibration 2.3 ANSI N15.15-1974, Assessment of the Assumption of Normality (Employing Individual Observed Values) 3.0 Method of Analysis Statistical procedures from Reference 2.1 were applied to determine the drift uncertainty value assuming the calibration interval will remain at 92 days per Technical Specifications.

4.0 Drift Analysis 4.1 Excel spreadsheets were populated with As-Found and As-Left data from work order history over the time frame from 1995 to 2008. The calibration interval for each relay (1B21-K114 A, B, E and F) is every 92 days (Reference 2.2). See the "Work Order Data, Table 1" sheets for the data obtained.

4.2 The data was combined into one table for analysis since the model number and setpoints are all identical for these instruments. See the "Combined Raw I Final Data Results, Table 2" for the combined data.

4.3 The mean, standard deviation and count statistics were calculated from the Excel spreadsheets for the raw data from, Combined Raw I Final Data Results, Table 2.

The results were:

Raw Drift Data Statistics mean 0.06 std. dev. 2.04837 2.05 rounded sample # 212 4.4 The raw data was then reviewed for potential outliers and outliers removed based on a work order review. No potential outliers were identified that could removed based on a review of the work orders for the 1B21-K114A, B, E and F relays.

4.5 A t-Test was performed on the raw data to identify any obscure value that might be an outlier. One data point that exceeded the critical value threshold could be removed from the population. The calculation to perform the t-Testwas as follows:

The critical value from Table 2 (Ref. 2.1) is determined based on a sample count of 212. The critical value was 4.00.

The formula for the t-Test is:

t = IXi - X I s

t is the calculated value of extreme studentized deviate that is compared to the critical value of t for the sample size.

Where; Xi = An individual raw data point X = 0.06 (mean of all raw data points) s = 2.05 (standard deviation of all raw data points)

A raw data sample point that might be considered an outlier is selected and the t-Test performed.

An individual sample point (Xi) of (-9) was selected from the raw data for the t-Test Therefore, t = 1 .061 = 4.42 2.05 The result of the t-Test performed for -9 indicates the result is larger than the critical value (4.00); therefore, this point is removed from the sample data. The data remaining is now considered the final data.

4.6 The mean and standard deviation were re-calculated along with the variance for the final data. The final data can be found in the "Combined Raw I Final Data Results, Table 2".

P @ 0.025 ::: 850.32 P @ 0.975 874.9 =

The 0' calculated value (813.33) falls outside the boundaries set by the P values interpolated from Table 5; therefore, the final data distribution is not considered normally distributed.

4.8 Coverage analysis I sample counting will be performed to determine an acceptable normal distribution model. This included developing a Histogram of the data for a visual representation of the final data. A Histogram of the final data can be found in" Relay 1B21-K114A,B,E,F Histogram, Table 4".

Review of the Histogram from Table 4 indicates relatively high peaks in the plot. The kurtosis of the final data is calculated from the Excel spreadsheets.

kurtosis ::: 1.672596 As discussed in Reference 2.1 a positive kurtosis indicates a distribution with high peaks and is a good candidate for sample counting to obtain an acceptable normal distribution model.

Sample counting is performed by determining how many sample points would encompass 95.45% of the total sample data. If at 2 standard deviations 95.45 % of the samples are not encompassed, the standard deviation is enlarged until 95.45 % of the samples are encompassed.

The steps for performing sample counting:

CALCULATION NO._....::...JC::::::...-.....::.Q'-'='1..;:::B=2~1-..;:;.:K~1~14..:......- REV._..:::...:OO=2:....--_ _

Calculate the percentage of points that encompass the final data at 2 standard deviations. The formula is:

std. dev. I< 2 Where; std. dey. =1.96 Therefore.

2:: 3.92 The total number of final data points that encompass the sample count value of 3.92 is 195 points.

195/211 :: 92.4% of the total sample points.

This is below the required 95.45%. The standard deviation of the model will be enlarged using a NAF ( Normality Adjustment Factor) that will encompass the required 95.45% of the data points.

The steps for performing the NAF were:

% samples required:: total samples * .9545 Where; total samples - 211 Therefore,

% samples required = 211 ....9545 = 202 Reviewing the final data sheet. Combined Raw I Final Data Results.

Table 2 a maximum drift value of 5 will be required to meet the percentage of samples required (202).

Therefore, NAF = max drift value 2'" std. dey.

Where; max drift value = 5 std. dey. = 1.96 NAF = _5_

2 It 1.96

= 1.28 A NAF multiplier of 1.28 to the std. dev. is required to obtain an acceptable normal distribution model for the final data.

4.9 A Drift Bias determination was performed on the final data to see if the data tended to drift in a particular direction. The formula for performing the Drift Bias was:

Xcrit = t x ..§

'.in Xcrit is the maximum value of non-biased mean for a given s & n, expressed in percent.

Where; t = 1.960 (Normal Deviate for at-distribution @ 0.025 for 95% Confidence from Table 4)

=

s 1.96 (standard deviation) n = 211 (sample count)

Therefore, Xcrit = 1.960 x 1.96 "211 Xcrit = 0.265 The mean of the final data (0.10) is less than the Xcrit value (0.265);

therefore. the final data drift is determined to be non-biased.

4.10 A 95%/95% TIF (Tolerance Interval Factor) is determined based on the sample size from Table 1 of Reference 2.1. The TIF from Table 1 for a sample size of 211 was 2.143.

TIF =2.143 5.0 Analyzed Drift Uncertainty Calculation The final analyzed drift value generally consists of two separate components, the random term and the biased term. As shown in Section 4.9 the final data was not biased; therefore, a bias term is not applicable to this calculation. The formula for calculating the drift uncertainty for the K114 relays was: )

Appendix 2 1821-K5A,B Drift Analysis 1.0 Purpose The purpose of this document is to calculate the drift uncertainty value to be used for the 1B21-K5A, B ADS Initiate Timer relays. The River Bend and Grand Gulf Nuclear Station Instrument Drift Analysis Guide (RBS/GGNS-002, Rev. 0), Reference 2.1, was utilized to determine the drift uncertainty value for these relays.

2.0 References 2.1 ECH-NE-08-00015, Rev. 1

River Bend and Grand Gulf Nuclear Station Instrument Drift Analysis Design Guide 2.2 06-EL-1 821-0-0001, Rev. 101, Surveillance Procedure ADS Timers Functional Test and Calibration 2.3 ANSI N15.15-1974, Assessment of the Assumption of Normality (Employing Individual Observed Values) 3.0 Method of Analysis Statistical procedures from Reference 2.1 were applied to determine the drift uncertainty value assuming the calibration interval will remain at 92 days per Technical Specifications.

4.0 Drift Analysis 4.1 Excel spreadsheets were populated with As-Found and As-Left data from work order history over the time frame from 1995 to 2008. The calibration interval for each relay (1 B21-K5A, B) is every 92 days (Reference 2.2).

See the "Work Order Data, Table 1" sheets for the data obtained.

4.2 The data was combined into one table for analysis since the model number and setpoints are all identical for these instruments. See the "Combined Raw I Final Data Results, Table 2" for the combined data.

4.3 The mean, standard deviation and count statistics were calculated from the Excel spreadsheets for the raw data from, Combined Raw I Final Data Results,. Table 2.

The results were:

Raw Drift Data Statistics mean -0.01 std. dev. 1.068953 1.07 rounded sample # 106 4.4 The raw data was then reviewed for potential outliers and outliers removed based on a work order review. No potential outliers were identified that could removed based on a review of the work orders for the 1B21-K5A, B relays.

4.5 A t-Test was performed on the raw data to identify any obscure value that might be an outlier. One data point that exceeded the critical value threshold could be removed from the population. The calculation to perform the t-Test was as follows:

The critical value from Table 2 (Ref 2.1) is determined based on a sample count of 106. The critical value was 3.28.

The formula for the t-Test is:

t= IXi - xl s

t is the calculated value of extreme studentized deviate that is compared to the critical value of t for the sample size.

Where;

=

Xi An individual raw data point X = -0.01 (mean of all raw data points) s = 1.07 (standard deviation of all raw data points)

A raw data sample point that might be considered an outlier is selected and the t-Test performed.

An individual sample. point (Xi) of (-3.62) was selected from the raw data for the t- Test.

Therefore,

=

t 1-3.62 - (-.01) I= 3.37 1.07 The result of the t-Test performed for -3.62 indicates the result is larger than the critical value (3.28); therefore, this point is removed from the sample data. The data remaining is now considered the final data.

4.6 The mean and standard deviation were re-calculated along with the variance for the final data. The final data can be found in the "Combined Raw I Final Data Results, Table 2".

The results were:

Final Drift Data Statistics mean 0.02 std. dey. 1.013462 1.02 rounded variance 1.027106 4.7 Normality testing was then performed on the final data to verify the data fits a normal distribution curve.

The D' test was performed to determine if the final data samples fit the normal distribution curve. The formula for the D' test is:

0' = TIS Where;

=

T Linear Combination of D'Stat 52 =Sum of the Squares about the mean S = Square root of S2 The steps to perform the D' test are:

Calculate T.

The formula for Tis:

i The number of the final data point n = Total number of final data points T is the Linear Combination of the D' statistic for each final data point.

The D' statistic for each point can be found in the Normality Test, TableII 3".

T = 2995.41 Calculate 52.

The formula for 52 is:

52 = (n - 1)S2 Where; n = 105 (Total number of final data points)

S2 = 1.027106 (Unbiased estimate of the sample population variance)

S2 = 106.82 Then calculate S.

S =Y'S2

= ~'106.82

= 10.34 To summarize the results were:

T =2995.41 S =10.34 Therefore, 0' is:

0' = TIS Ot = 2995.41/10.34

=289.82 From Table 5 of Reference 2.3, for a sample count of 105 the following P values were interpolated:

P @ 0.025 = 296.3 P @ 0.975 =308.4 The 0' calculated value (289.82) does not fall inside the boundaries set by the P values interpolated from Table 5; therefore, the final data distribution is not considered normally distributed.

4.8 Coverage analysis I sample counting will be performed to determine an acceptable normal distribution model. This included developing a Histogram of the data for a visual representation of the final data. A Histogram of the final data can be found in" Relay 1B21-K5A,B Histogram, Table 4".

Review of the Histogram from Table 4 indicates relatively high peak in the plot. The kurtosis of the final data is calculated from the Excel spreadsheets.

kurtosis = -0.02135 As discussed in Reference 2.1 a negative kurtosis indicates a relatively flat distribution when compared to a normal distribution model.

Sample counting is performed by determining how many sample points would encompass 95.45% of the total sample data. If at 2 standard deviations 95.45% of the samples are not encompassed, the standard deviation is enlarged until 95.45% of the samples are encompassed.

The steps for performing sample counting:

CALCULATION SHEET ENTERGY SHEET_4.;....::.6_ OF _62_

CALCULATION NO ._,.;;.-JC..=. -. . . : oO"-=1.=B.=.2=--l--=-=K:.: . l-=-14..:. . . - REV._....;;;..00=2=---_ _

Calculate the percentage of points that encompass the final data at 2 standard deviations. The formula is:

std. dev. "42 Where; std. dev. = 1.02 Therefore.

1.02" 2 2.04 =

The total number of final data points that encompass the sample count value of 2.04 is 103 points.

103/1 05 =98.09% of the total sample points.

This is above the required 95.45%; therefore the data is considered normally distributed.

4.9 A Drift Bias determination was performed on the final data to see if the data tended to drift in a particular direction. The formula for performing the Drift Bias was:

Xcrit =t x ..§

,in Xcrit is the maximum value of non-biased mean for a given s & n, expressed in percent.

Where; t = 1.980 (Normal Deviate for at-distribution @ 0.025 for 95% Confidence from Table 4)

=

s 1.02 (standard deviation) n = 105 (sa mple count)

Therefore, Xcrit = 1 .980 x 1.02

..i 105 Xcrit = 0.197 The mean of the final data (0.02) is less than the Xcrit value (0.197);

therefore, the final data drift is determined to be non-biased.

4.10 A 95%/95% TIF (Tolerance Interval Factor) is determined based on the sample size from Table 1 of Reference 2.1. The TIF from Table 1 for a sample size of 105 is 2.233.

TIF =2.233

5.0 Analyzed Drift Uncertainty Calculation The final analyzed drift value generally consists of two separate components, the random term and the biased term. As shown in Section 4.9 the final data was not biased; therefore, a bias term is not applicable to this calculation. The formula for calculating the drift uncertainty for the K5 relays was:

DR K6 = TIF

std. dey.

Where; TIF =.2.233 std. dey. = 1.02 Therefore, DR K5 = 2.233 *1.02 DRK5 = +/- 2.28 sec.

CALCULATION NO._...::..JC;::::"--.:::IQ~I.=E.;:;..:I2=--K~09:....:::3 REV. 001 1.0 PURPOSE The purpose of this calculation is to determine the instrument loop uncertainty, limiting allowable values and set points for instrument loops IEI2K093A,B. The values generated by this calculation are in accordance with reference 3.1.1.

2.0 DESIGN REQUIREMENTS Containment Spray is an operating mode of the RHR system wherein water discharged from the RHR pumps is directed through heat exchangers to spray headers located near the top of the containment. This spray passes down through the containment atmosphere condensing steam, removing energy from the atmosphere to limit containment pressure rise resulting from a LOCA or HELB inside containment, and promoting removal of iodine from the containment atmosphere (Ref. 3.1.2, p.6).

Containment Spray "A" is initiated by LPCS initiation (high drywell pressure or low water level) after about a 10 minute time delay (IEI2K093A) to permit the RHR system to operate in LPCI mode to recover core water level in the event of a LOCA (Ref. 3.1.2, p.6).

Containment Spray "B" is initiated by a LOCA detection (high drywell pressure or low water level in the reactor) coincident with high containment pressure after about a 10 minute time delay (lEI2K093B) followed by a short time delay of less than 5 seconds (lEI2AKI16). The system may also be initiated manually (Ref. 3.1.2, p.15; 3.1.7- 3.1.9)

The initiating event for equipment addressed by this report is high drywell pressure or low water level resulting from an accident - LOCA or HELB. However, the timers are located in the control room where accident conditions are no more severe than normal. Therefore, the timers will be required to function in normal environments as described in reference 3.1.20.

The RHR system which includes the Containment Spray Subsystem is designed in accordance with the requirements for Category I equipment and must function during and after a seismic event (Ref. 3.1.2, p.8).

For instrument loops lE12K093A,B the upper analytical limit (AL) is 11.7 minutes and the lower analytical limit is 10.0 minutes (Ref. 3.1.19). The Technical Specification allowable value (AV) is ~10.26 min :::;11.44 min (Ref. 3.2.1). The TRM setpoint is ~10.75 min :::;10.95 min (Ref. 3.2.1).

5.0 ASSUMPTIONS 5.1 Not used.

5.2 The vendor provides a single 'repeatability' value for normal and extreme environmental conditions and voltages. Since these conditions include temperature, pressure, radiation and voltage specifications, it is assumed that RA, TE, HE, RE and PS are included in the repeatability value. Based on the vendor defined normal environment identified in sections 4.3 and 4.4 and the operating environment identified in section 4.2, the accuracy value given for normal environmental conditions (5.0% setting) shall be used.

5.3 Vendor documents list equipment performance data without stating the statistical basis for the numbers. Although some vendor data is "worst case" it will be assumed that all such data is a 2 sigma value.

5.4 Per reference 3.1.1, the M&TE error is normally assumed to be equal to the reference accuracy of the instrument. Per reference 3.1.18, for the K093A & B relays, the test equipment used to determine the setpoint has an accuracy of +/-0.5 seconds. The setting tolerance is +/-6.0 seconds for both loops (K093A alone and K116 + K093B together),

per reference 3.1.18. Therefore, for the K093A & B relays, the setting tolerance of

+/-6.0 seconds (0.1 min), will be used as input for the M&TE error. For the K116 relay, a setting tolerance of +/-O.O seconds will be used since the M&TE error is accounted for with K093A.

5.5 No drift data regarding the AmeracelAgastat model ETR timer relay used for lE12K093A was available from the vendor. However there is historical calibration data available. This data was used to calculate the drift based on the calibration interval. The drift analysis resulted in value of +/-8.81 seconds (Appendix 1). The drift value is for a 115 day period.

5.6 No drift data regarding the Amerace/Agastat model ETR timer relay used for lE12K093B & lE12AK116 was available from the vendor. However there is historical calibration data available for the loop which includes both the K093B and K 116 relays in series. This data was used to calculate the drift based on the calibration interval. The drift analysis resulted in value of +/-10.52 seconds (random), +1.43 seconds (bias) (Appendix 2). The drift values are for a 115 day period.

5.7 The timer relays are seismically qualified devices. Since the vendor does not identify any seismic effect error for the timer relays it is assumed that any seismic effects are included in the reference accuracy.

6.5 Nominal Trip Setpoint The nominal trip setpoint will be calculated using the reference 3.1.1 equation:

NTSP = AL +/- TLU 6.6 Spurious Trip Avoidance The probability of a spurious trip during normal plant operation using the Tech Spec setpoint will be evaluated using the methodology of reference 3.1.1 and calculated loop errors. Per reference 3.1.1, a 95% probability of no spurious trip is acceptable.

6.7 LER Avoidance The probability of exceeding the Tech Spec allowable value without a trip at the tech spec setpoint will be evaluated using the methodology of reference 3.1.1 and calculated loop errors. Per reference 3.1.1, a 90% probability of avoiding LERs is acceptable. A Z of 1.28 corresponds to a probability of 90%.

6.8 Nomenclature The calculation will performed for each loop therefore the uncertainties and calculations will be uniquely identified. The nomenclature of reference 3.1.1 will be used with the following modification:

The terms associated for the system A loop are A, and the terms associated with the loop for the system B will be B. Terms associated with system B timer, K93B, will be subscripted with a "I". Terms associated with system B timer, K116, will be subscripted with a "2". Therefore, RA Bl refers to the K93B relay Reference Accuracy, RAB2 refers to the K116 relay Reference Accuracy, A B refers to the loop Accuracy.

6.9 Worst Case Loop Because there are two different loop arrangements under consideration in this calculation, the system "A" and "B" loop uncertainties and limiting allowable values and setpoints will be calculated separately.

Per section 4.2 all timing relay environments are identical.

7.0 CALCULATION 7.1 System A Uncertainties The only device in this loop is the Amerace time delay relay. The accuracy of a time delay relay is determined by (1) the value initially set in, determined by calibration accuracy, (2) the repeatability, and (3) the drift:

An initial determination of the setpoint will be made for use in determining the loop uncertainty. Because this loop has upper and lower limits, the upper setpoint Technical Specification limit will be chosen since it will provide more conservative results.

Setpoint = 11.44 min 3.2.1 Using the error values from section 4.3 (Assumption 5.2):

RA A = +/- 50/0 setpoint (combined vendor value)

= +/- (0.05)*(11.44)

= +/- 0.58 min The environment ranges are within the vendor data ranges, therefore:

TEA = 0.0 min REA = 0.0 min REA = 0.0 min PS A = 0.0 min SEA = 0.0 min, per Assumption 5.7.

The relay vendor does not provide a drift error. Drift is determined using calibration data (Assumption 5.5).

DA = +/- 0.15 min 7.2 System B Uncertainties There are two Amerace time delay relays in this loop with one of the relays presently set to minimum. The uncertainties associated for each relay will be calculated separately and then they will be combined to determine the loop accuracy values. The accuracy of a time delay relay is determined by (1) the value initially set in, determined by calibration accuracy, (2) the repeatability, and (3) the drift.

An initial determination of the setpoint will be made for use in determining the loop uncertainty. Because this loop has upper and lower limits, the upper setpoint Technical Specification limit will be chosen since it will provide more conservative results.

Overall Setpoint (K093B + Kl16) = 11.44 min. 3.2.1 K116 Setpoint alone = 10 sec. (0.17 min.)

Because the K116 lower setpoint limit is zero seconds (Ref. 3.1.18), the K093B setpoint will be taken to be the entire overall Tech. Spec. time limit for the purpose of calculating errors associated with K093B, while the K116 setpoint will be taken as the upper Tech. Spec. limit for that relay:

K93B relay = 11.44 min.

K116 relay = 0.17 min.

Using the error values from Section 4.3 and 4.4 (Assumption 5.2):

For K93B:

RA B 1 = +/- 50/0 setpoint (combined vendor value)

= +/- (0.05)*(11.44 min)

= +/- 0.58 min The environment ranges are within the vendor data ranges, therefore:

TE B1 = 0.0 min HE B1 = 0.0 min RE Bl = 0.0 min PS B1 = 0.0 min SE S1 = 0.0 min, per Assumption 5.7.

The relay vendor does not provide a drift error. Drift is determined using calibration data (Assumption 5.6).

The procedure I~)r perfot1ning the \V-Test is referenced in Section 3.7.2 of Refercnce 2.1 and dctailed in Reference 2.3.

111e data set is 11rst sorted in order of ascending value (largest negative value to largest positive value). The order is thcn reversed and juxtaposed with the first ordering, such that the largest negative value is now paired with the hU'gest positive value. This creates a series of data pairs. See Table 5.

Using only the top half of the data pairs, the ordered pairs are subtracted from each other. For a data set comprising 28 points; this results in 14 values.

R(;~terring to Table 1 of Reference 2.3, nine coeJlicients are obtained, ordered ne>..1 to the nine subtracted values. Each coe.t1icient is then multiplied by its corTesponding subtracted value. The resulting nine numbers are then sUlnmed, with the sum labeled ,1S the 'b' value.

'n,e procedure for this is {()lind in Section 3.7.5 of reference 2.1. Non-normal data distributions exhihiting a positive kurtosis are good candidates for coverage analysis. I11e final data set here has u kurtosis of 1.4707, using the kurtosis function of Excel, and therefore can he conservatively modeled llsing an appropriatenormaJ distrib,ution.

If less than 95(~'l) of the data falls between those bounds, a Nonnality Adjustmcnt Factor (NAF) is cmployed to widen the boundc;until the 95~1o criterion is met.

111e data was then review'ed for potential outliers based on using the i-Test (Extreme Studentizcd Deviate in accordance with Section 3.6 of Reference 2.1. Because this section allows only one expulsion bused on the t- Test, only the hU'gest data point should be analyzed (7.0 seconds). Tlowever, because there are two dahl points of7.0 seconds, it is deemed inappropriate to reject one of them and leave the other. Therefore, no duta points will be rejected as outliers.

'111e procedure tor pCrf0l111ing the \V-'1'05t is referenccd in Section 3.7.2 of Reference 2. I and detailed in Reference 2.3.

111e data set is first sorted in order of <L",cending value (largest negati ve value to largest positive value). 'l1,e order is then reversed and juxtaposed

)with the first ordering, such that the largest negative value is now paired with the largest positive vuluc. This creates a series of data pairs. Sec Tahle 5.

Using only the top half of the data pairs, the ordered pairs are subtracted from each other. For a data sd comprising 30 points, this results in 15 values.

Rt~felTing to Table 1 of Reference 2.3, liJteen coefficients are obtained, ordered nex1 to the .fifteen subtracted values. Each c()etlicient is then multiplied by its corTesponding subtracted value. The resulting fifteen numbers are then sumtned, with the slim labeled as the 'b' value.

For 30 sample points andP 01.'0.05 (co11'esponding to 95~'O probahility), the critical value is 0.927. Because the calculated value is smaller than the critical value (0.8866 < 0.927), the assumption of a not111al distribution is rejected and the da.ta set cannot be assumed to be nonnally distributed.

4.6 Although the data cannot be assumed n0I111ally distributed, coverage analysis may he perfonlled if it is conservative to assume normality based on the actual data distribution. 'l1,e procedure f()I" this is f()und in Section 3.7.5 of reference 2.1. Non-normal data distributions exhibiting a positive kurtosis arc good candidates for coverage analysis. 'n,e 1'1nal data set here has a kurtosis of 1.2933, using the kurtosis function of Excel, and therefore can be conservatively modeled lL<;ing an appropriate nonnal distribution.

Sample counting is used to derive an aCI.:eptable nomul! distribution model. If 95%, of the data points t~lll between limits detined by the sample mean plus or minus two standard deviations, then the data set C,Ul be described by nonnal statistics. If less than 95~/o of the dala tails between those bounds, a NOllnality AdjuStlllent Factor (NAF) is employed to widen the bounds until the 95(% criterion is met.

tJsing a sample meun of <),0357 and a standard deviation of2.1514, the limiting bounds are deteJ111ined and the number and percentage of data points falling within the bounds are counted:

Calculation JC-Q 1R21-90024-1 Rev 2 Page 5 of23 1.0 PURPOSE AND DESCRIPTION 1.1 The purpose of this calculation is to validate the Setpoint and upper allowable value for the second level Load Shedding and Sequencing (LSS) 4160 V Division I & II bus undervoltage trips. The existing tech spec lower allowable value is unacceptable per CR 2009-1664 since it is equal to the analytical limit. A new tech spec lower allowable value will be determined in this revision.

1.2 The second level of bus undervoltage is defmed as degraded bus conditions as signified by the sensing of undervoltage bistables from the 4160 V buses set at 90% of nominal bus voltage, with a 9 second time delay. (Ref 2.3) 1.3 The second level bus undervoltage function protects equipment I motors from any adverse effects of sustained degraded voltage, and prevents spurious separation of offsite power sources from Class IE loads due to normal power transients (e.g. starting large motors) or from short duration power system disturbances. (Ref 2.3) 1.4 The second level voltage sensors automatically initiate via the LSS panel the tripping of the offsite power sources whenever the voltage setpoint and time delay limits have been exceeded and send a start command to the diesel generator. Once the diesel generator reaches rated speed and voltage and the diesel generator breaker closes, the LSS system sequences the required loads for loss of power.

(Ref 2.3) 1.5 The lower analytic limit is based on the capability to start required Class IE loads under accident conditions with degraded voltage levels present on the distribution system. Voltage sensing is performed by potential transformers located within the 4160 V switchgear for each division. Each potential transformer has 4200 VI 120V ratio. Calculation EC-Qllll-90028 results support the conclusion that the required loads will start with 3744 V available atthe respective 4160 V buses. This corresponds to 106.97 V on a 120 V base, at this location.

The upper analytic limit is based on prevention of unnecessary separation of the Class 1E buses, under anticipated minimum voltage conditions of the offsite sources. Per GIN 2011-00405, this correlates to 110.49 V on a 120 V basis.

The upper analytic limit for the degraded voltage time delay is based on the safe stall time of the motor loads. The motors are suitable for running at 90% rated voltage and have a safe stall time of 10 seconds, or more at rated voltage. Since the safe stall time of a motor is inversely proportional to the square of the applied voltage, operation at a reduced voltage will result in a corresponding increase in safe stall_ time. (Ref 2.3)

The lower analytic limit for the degraded voltage time delay is based on the start sequence of the LSS loads. The 5 second loading intervals ensure that the large motors will have reached rated speed and that voltage and frequency have stabilized before adding successive loads. (Ref2.3) 1.6 The design consideration for the subject instrumentation is: Degraded Grid Voltage

Calculation JC-Q 1R21-90024-1 Rev 2 Page 6 of23 1.7 This calculation is performed in accordance with the methodology ofGGNS-JS-09, which is based on the 'square root sum of the squares' (SRSS) technique for combining statistically independent uncertainty components.

4.2 Assume Radiation Effects (RE), Humidity Effects (HE), Temperature Effects (TE), and Temperature Drift (TD) for the time delay cards are negligible. These components are located in a mild environment. (Ref. Sections 3.1.3 & 3.2.3). Note also that qualification testing per Reference 2.7 demonstrated satisfactory equipment performance with ambient temperatures from 4°C (39.2°F) to 50°C (122°F) and relative humidity to 900/0.

4.3 Assume Seismic Effects (SE) are negligible for the loop components since all are solid state devices.

4.4 Assume Power Supply Effects for time delay cards are negligible based on satisfactory qualification testing with power supply variations from 105 VDC - 140 VDC as documented in Reference 2.7.

4.5 Insulation Resistance Effects (IR) are assumed to be negligible since the loop cabling is located in a mild environment (control building).

Calculation JC-Q 1R21-90024-1 Rev 2 Page 12 of23 4.6 The drift analysis presented in Attachment 1 is assumed to be applicable for both Div. I and Div. II.

The equipment is identical and the ambient environment is almost identical for both divisions. The Div 1 max temperature is 110F and the Div II max temp is 104F. Only the calibration data taken after the new power supplies were installed in 2005 is included. This is conservative because the poor stability of the new power supplies is causing increased setpoint drift (reference CR 2008-4711).

Using the as-found and as-left calibration data to determine drift is extremely conservative since this drift value will also include all other uncertainties such as reference accuracy, temperature drift and M&TE.

4.7 Per the qualification report (ref2.7), the tolerance of the bistable trip is +/-0.05 V. Since the calibration procedure (ref2.4) specifies a tolerance of +/-0.2 V, this is the accuracy that will be assumed. The 1%

accuracy value specified in the vendor manual (ref 2.5) is overly conservative since it apparently includes a drift allowance (reference 2.27).

4.8 Assume Radiation Effects (RE) and Humidity Effects (HE) for the Bistable cards are negligible. These components are located in a mild environment. (Ref. Sections3.1.3 & 3.2.3). Note also that qualification testing per Reference 2.7 demonstrated satisfactory equipment performance with relative humidity to 900/0.

4.9 The maximum measured reset deadband for div 2 LSS is 0.6 V per reference 2.31. It is assumed that the max div 1 deadband will also be 0.6 V. This will be confIrmed via reference 2.34.

5.0 DEVICE UNCERTAINTIES -Ax(Ref. 2.1) 5.1 Bistable Card Uncertainties: (Ref Section 3.1.4)

Reference Accuracy - "RA" RAss = +/-0.2 V (setpoint)

Temperature Effects - "TE" Per reference 2.7 and 2.27, the temperature effect for a 40F to 32F (8F) temperature change is 0.06% and 0.60/0 for a 40F to 140F (100F) temperature change. Based on E100.0 the maximum temperature fluctuation is 58F-110F (52F). Using linear interpolation the temperature effect for a 52F temperature change is:

TE = 0.06% + (0.60/0-0.060/0) {(52F-8F)/(1 00F-8F) }= 0.320/0

=0.32%(109.65 v) = 0.35 V at upper allowable value However, this value is overly conservative. Based on PDS trends of computer points Z77N030 &

Zi7N031, the monthly fluctuation in room temperature is only about 20F (average). It is conservatively assumed that half of the above Temperature effect value needs to be considered and that the remainder is

Per Reference 2.4, a Fluke 45 Digital Voltmeter (or equivalent) is used in the calibration of the bistable trip cards. The uncertainty data for a Fluke 45, taken from Ref. 2.6, will be used to estimate the M&TE effects. The reference accuracy of the Fluke 45 is:

RAF45 = +/-(0.2% reading + 0.1 V)

The reference accuracy above is for the 0-300V scale, medium resolution. This value is valid for ambient temperatures between 18°C and 28°C (64.4°F to 82.4°F). Since the expected temperature at calibration (l04°F, i.e. 40°C) is outside the given range, a temperature correction factor from Ref. 2.6 must be applied. This correction factor is stated as: '< 0.1 times the applicable accuracy specification per degree C for O°C to 18°C and 28°C to 50°C (32° to 64.4° and 82.4° to 122°F). The temperature correction factor for this application is : <0.1 (40-28) or 1.2.

The 'reading' will be conservatively assumed to be 109.65V (Upper Allowable Value). Since no other test equipment is used for the calibration, the loop calibration uncertainty is:

0.2 CL = +/- 1.2 -(109.65) + 0.1 J V= 0.38 V

6.5 Primary Element Uncertainty - "PE" The primary elements for each bistable loop are the potential transformers at the buses. Per reference 2.19, the accuracy class of the potential transformers is 0.3. Per Reference 2.18, the limits of transformer correction factor for a 0.3 accuracy class potential transformer are 1.003 to 0.997 (i.e. +/- 0.3%). Again assuming 109.65V nominal output (Upper Allowable Value), the potential transformer uncertainty is:

PE = +/-( 0.3 (109.65)) V 100 PE = +/-0.33 V No Primary Element Uncertainty is applicable to the time delay.

6.19 Spurious Trip Avoidance Analysis - Time Delay A spurious trip analysis is not applicable in this application.

7.0 CONCLUSION

Bistable Trip:

The existing setpoint and reset are conservative compared to the calculated values.

Note, the drift value used in the calculation was derived from as-found / as-left surveillance data. A drift value determined in this fashion will include the combined effects of reference accuracy, measurement and test equipment, and environmental influences (Ref. 2.28). For this calculation, reference accuracy and M&TE effects are accounted for individually. The drift term would therefore include inherent conservatism.

Time Delay:

The existing plant setpoint and allowable values are conservative with respect to the calculated values. The existing plant setpoint is acceptable.

CALCULATION NO. JC-01P81-90024 REV. 004 1.0 PURPOSE AND DESCRIPTION 1.1 The purpose of this calculation is to validate the Technical Specification Allowable Value and TRM Nominal Trip Setpoint for the 4160 V Division III Degraded Bus Voltage trip function.

1.2 The incoming breakers for the Div. III switchgear are automatically tripped on a degraded bus voltage condition after a time delay. The degraded bus voltage condition is detected by sensors employing a one-out-of-two-twice logic. An undervoltage between 88% and 73% of nominal is considered a 'Degraded Voltage'. (Ref. 2.13) 1.3 The time delay for a bus 'Degraded Voltage' condition is long enough to provide for the preferred power source (offsite power) to recover. This time delay duration is dependent upon the presence (or absence) ofa LOCA signal. (Ref. 2.13) 1.4 The upper and lower analytic limits for the Division III degraded voltage setpoints and time delays are derived from the station specific load flow and voltage drop calculation (EC-Qllll-90028), BYron Jackson HPCS Pump Test Curve (#PC 741-S-1404), GE HPCS Motor Time Current Heating Curve (# 455HA550), GE HPCS Motor Efficiency and Power Factor Vs. Load Curves (# 455HA549), NEDO 10905-1, and GE HPCS Motor Outline Dwg. (#992C937CF).

The lower analytic limit for the voltage sensors is based on the capacity to start and operate required Class 1E loads under accident conditions with degraded voltage levels present on the distribution system. Voltage sensing is performed by potential transformers located within the 4160 V switchgear for the division, and each potential.

transformer has a 4200 V/ 120V ratio. The HPCS system is designed to start and accelerate the HPCS Pump with 750/0 of 4000 V motor voltage (3000 V), per NEDO 10905-1. In order to continue operation indefinitely at the lower analytic voltage limit, motor heating must be limited to that imposed by curve #455HA550, which equates to rated current of the motor @ 434 A. Per PC 741-S-1404, the maximum power point for the HPCS Pump is less than 3100 Hp. At this operating point, the efficiency is 0.935, and the Power Factor is 0.93, per Curve #455HA549. Therefore, at the maximum power point, with the motor drawing 434 A, the terminal voltage at the motor would be 3538 V. Per EC-Qllll-90028, the voltage drop is very conservatively calculated to be 5.41V. This places the 4160V bus at 3543.41 V for a sustained undervoltage condition limit. This correlates to a voltage of 101.24 V on a 120 V basis, and is the lower analytic limit (Reference 2.27).

The upper analytic limit for the voltage sensors is based on prevention of unnecessary separation of the Class 1E buses, under anticipated minimum voltage conditions of the offsite sources. Calculation EC-Qllll-90028, conservatively analyzed the Class IE loads with the 500kV Offsite source at 0.975 Per-Unit and the 115kV Offsite source at 0.9675 Per-Unit. It was determined that the Class IE system required loads would be adequately supported with 0.975 Per-Unit switchyard voltage available for the 500kV

CALCULATION NO. JC-OlP8l-90024 REV. 004 system and 0.9675 Per-Unit for the l15kV system. Therefore, it is appropriate that the upper analytic limit for the degraded voltage setpoint determinations be based on the corresponding voltage available at the respective 4160 V Class IE buses, with 0.975 Per-Unit 500kV system driving voltage or 0.9675 Per-Unit l15kV system driving voltage in each switchyard, under accident conditions. The lowest available transient voltage on the Division III 4160 V bus under these conditions has been calculated to be 3359.2 V, which occurs during the start of the HPCS pump, with bus voltage recovery to 3880.9 V within 5 seconds. This condition provides an initial terminal voltage at the HPCS pump motor of3329.25 V, with voltage increasing as the motor accelerates. The second lowest transient voltage step is 3846.34 V, with bus voltage recovery to 3904.16 V, within 5 seconds. This interval is after the HPCS pump motor is already started, therefore the acceleration time of this load is not a factor. All other bus voltage steps are calculated to remain above 3880.9 V. The recovery voltages referenced include the start demand of the next sequence interval, therefore actual recovery voltages at the end of each step following load acceleration and prior to the next sequence would be above these values. Therefore, if the HPCS motor can accelerate its load at the minimum transient voltage within the allowable time delay band, the recovery voltage predicted would form the upper analytic limit for degraded voltage considerations during the sequence when the HPCS pump motor starts. For all successive intervals, using the lowest available bus voltage step will ensure that other equipment sequencing will not inadvertently actuate the Division III bus degraded .

voltage sensors. As stated above, this correlates to a bus voltage of 3846.34 V. This value would bound all required conditions for the HPCS system to remain connected to offsite power, without prematurely separating from this source, provided that the time delay is set sufficiently to account for HPCS motor start time. Therefore, the overall bounding upper analytic limit is 3846.34 V (109.89 V on a 120 V basis), and the appropriate sensor time delay interval will also be based on this value (Reference 2.27).

Division III has two distinct time delays associated with degraded voltage sensing.

One time delay is active when no accident signal is present, and the other is active when a safety injection signal is present for Division III.

The lower analytic limit for the safety injection condition time delay is based on providing the capability to successfully start the HPCS pump at the lower analytic limit of the degraded voltage sensors without segregating from the offsite source. This requires that the time delay be of sufficient duration to allow for acceleration of the HPCS pump motor under these conditions. Using the previously established minimum HPCS motor starting voltage available from a viable offsite source of 3329.25 V, the acceleration time for the HPCS pump motor has been determined to be no more than 3.28 Seconds. This condition conservatively bounds the acceleration time required at the lower analytic limit bus voltage of3543.41 V. Therefore, 3.28 seconds is the lower analytic limit for the safety injection condition degraded voltage time delay.

CALCULATION NO. JC-OIP81-90024 REV. JillL The upper analytic limit for the safety injection condition degraded voltage time delay is derived from the required time response for the HPCS system to achieve necessary injection flow within 27 Seconds of accident initiation. This further requires that the HPCS system be connected to a viable power source within 10 seconds to achieve this goal. The limiting case for this upper limit is when offsite power is available but degraded (i.e, above the Loss of Voltage settings, but below the lower analytic limit for the degraded voltage sensors), with an accident signal present. This is because the degraded voltage function trips the incoming source only, therefore requiring the subsequent sensing and time delay from the Loss of Voltage function to connect the Emergency Diesel Generator (EDG) to the bus. The EDG receives a separate safety injection signal, so the EDG start time and the total voltage sensing sequence described will occur concurrently. This limits the allowed combined sense and actuate times for the degraded voltage and loss of voltage functions to no more than 10 seconds total. It is desirable that the degraded voltage time delay be of a longer duration than the loss of voltage time delay, based on original system design.

Therefore, a 6 Second upper analytic limit is allocated to the degraded voltage time delay. Correspondingly, a 4 Second upper analytic bound is thus established for the loss of voltage time delay by this selection.

For GGNS, the existing time delay settings are acceptable, provided that the degraded voltage remains sufficiently Qigh to start the HPCS loads. This correlates to a motor terminal voltage of 75°!<J of the motor base voltage for HPCS system motors. Review of calculation EC-Q 1111-90028, has determined that the bounding percent voltage drop from the offsite source to the HPCS pump motor is considerably less than 15%,

even under the motor start demand conditions. A 150/0 drop will be conservatively assumed for this discussion. The HPCS system motors are designed to start with 75%

of motor rated voltage. This is 3000 V for the HPCS pump motor. 3000 V is less than 73% of rated bus voltage (4160 V). Therefore, the HPCS pump motor would be expected to start for offsite source degraded voltage conditions down to 88% of rated offsite source voltage (730/0 + 15% = 88%). The remaining consideration for continued relay timing limitations would be the motor heating limits once the motor has started. Motor heating must be limited to that imposed by curve #455HA550. Per PC 741-S-1404, the maximum power point for the HPCS Pump is less than 3100 Hp.

At this operating point, the efficiency is 0.935, and the Power Factor is 0.93, per Curve

455HA549. Therefore, at the -maximum power point, with 3000 V available at the motor, the current would be 511.83A (1.18 PU) under these conditions.

Per the motor heating curve, operation at this current level can continue in excess of 600 seconds, which is significantly longer than the present time delay settings require.

Thus, the present settings are justified for offsite source degradation levels down to at least 88% of rated.

With these considerations, it would be appropriate to select 600 seconds (10 min.) as the upper analytic limit for the Division III Time Delay, No LOCA. For additional conservatism, this limit will be set at 360 seconds (6 min.). This provides adequate

JC-01P81-90024 REV. 004 time for voltage recovery to above the degraded voltage set-point, while ensuring the continued automatic availability of the system, should a subsequent LOCA signal be received. The lower analytic limit for this parameter should be based on a reasonable period to allow time for recovery. It is to be selected to provide an equivalent margin from the nominal trip setpoint as the margin allowed from the setpoint to the upper analytic limit (i.e. 1 min.). Therefore, the lower analytic limit for the Time Delay, No LOCA is 4 minutes.

4.2 Assume Radiation Effects (RE) and Humidity Effects (HE) for the undervoltage and time delay relays are negligible. These components are located in a mild environment.

(Ref. Section 3.1.3 and 3.2.3) 4.3 Assume Seismic Effects (SE) are negligible for both the undervoltage and time delay relays. The relays are seismically qualified per GGNS QP 425.00 Vol. 1, Rev. 1.

4.4 Per Reference 2.1, Temperature Effect (TE) is usually assumed to be applicable for temperature variations outside the assumed normal calibration temperature range of 65°F to 90°F and Temperature Drift (TD) is assumed to apply to temperature variations within the normal calibration temperature range. In this calculation, a calibration temperature range of 58°F to 90°F is conservatively assumed for the undervoltage relays. Since the maximum temperature the relays will be exposed to is 120°F (per 4.6), TE is assumed to apply from 90°F to 120°F. The vendor manual for the relays (Attachment 2) specifies a temperature effect of 0.2% setting for O°C to 40°C (32°F to 104°F) and 0.4% setting for -20°C to 55°C (_4°F to 131°F). Although 120°F is above the specified 104°F maximum temperature for the 0.2% setting TE, the

Total Pa es: 16 of 51 CALCULATION SHEET ENTERGY SHEET 16 OF 2L CALCULATION NO. JC-O 1P8l-90024 REV. J!QL expected delta T is only 62°F (120°F - 58°F) instead of 72°F (104°F - 32°F). The vendor test data in Reference 2.2 verifies it is conservative to assume a 0.2% setting TE. The vendor would not confirm that TE was linear with delta T. Therefore, the entire 0.20/0 setting error will be assumed to apply over the range of 58°F to 120°F. It will be divided between TD (58°F to 90°F) and TE (90°F to 120°F).

4.5 Insulation Resistance Effects (IR) are assumed to be negligible since the loop cabling is located in a mild environment (control building).

4.6 Per E100.0, the normal ambient temperature range ofOC2l0 is 58°F to 110°F. It is assumed that the cabinet temperature will be 10F above ambient or 120°F max (cabinet closed). The minimum cabinet temperature is assumed to be 58°F (door open for calibration with no heat rise). The ambient room temperature could reach l20F with greater than design basis outside air temperature, but this condition is not required to be considered here.

4.7 Per Reference 2.21 and 2.22, the potential transformers at the bus are G.E. type JVM-

3. This type of potential transformer has an accuracy class of 0.3 at Wand X burdens when operated at 580/0 of rated voltage. Based on the available burden information for the circuit components depicted on Ref. 2.16 and 2.18, the burden is assumed to be less than X and the accuracy of the potential transformers is assumed to be 0.3. (See file documentation for available circuit component burden data) 4.8 Reference 2.23 specifies time delay repeatability shall be within +/-5% of the delay time setpoint during normal plant operating cycle at normal environmental conditions and voltages. It specifies time delay repeatability shall be within +/-100/0 of the delay time setpoint during normal plant operating cycle at extreme environmental conditions and voltages. The accuracy of the ETR time delay relays is assumed to be 2% of the setpoint at fixed temperature/voltage based on Reference 2.11. The 2% value would, therefore, be the reference accuracy (RA) and the 5% or 10% values would be the device uncertainty (A). The device uncertainty is assumed to include power supply effects, temperature effects and temperature drift. Reference 2.23 specifies the "normal" ambient temperature range for the ETR relays is 60°F-90°F, the "abnormal" max temperature is 104°F and the "DBE" max temperature is 120°F. The 100/0 device uncertainty value must be used since the relays will be exposed to a temperature range of 58°F to 120°F per Section 4.6. The setting tolerance of the time delay relay was changed from 10% to 5% in Revision 24 (1994) of Reference 2.6. The setting tolerance was changed from 5% to 20/0 in Revision 103 (2014) of Reference 2.6.

4.9 Not Used.

4.10 The vendor does not specify a Temperature Effect, Temperature Drift or Power Supply Effect for the undervoltage relay timing function. It is likely that there is some effect.

Therefore, it will be assumed that the Reference Accuracy (RA) of the undervoltage relay timing function is 5% instead of 1oo~ as specified in Reference 2.9 (Attachment

Total Pa es: 17 of 51 CALCULATION SHEET ENTERGY SHEET 17 OF--.lL CALCULATION NO. JC-OIP81-90024 REV. JlliL 1). The device uncertainty will then be assumed to be 10(% and will be assUlned to include Temperature Effect, Temperature Drift and Power Supply Effects. The setting tolerance of the undervoltage relay time delay was changed fron1 10% to 50/0 in Revision 24 (1994) of Reference 2.6.

6.22 Spurious Trip Avoidance Analysis - Voltage Trip The most severe recoverable voltage transient postulated, is that of clearing a nearby translnission system or in-plant distribution systenl bolted fault. The bus voltage level during such an event could dip below the voltage trip setting and begin the relay timing. Therefore, no spurious trip avoidance analysis will be perfo fl11 ed for the voltage trip setting. Spurious segregation from the off-site source is prevented by the tinle delay function.

6.23 Spurious Trip Avoidance Analysis - Time Delay LOCA The probability of avoiding spurious trips is determined by calculating a value "z" as shown below. lfthe value of Z is 2: 1.645, the probability of avoiding a spurious trip is 2: 95%. (Ref. 2.1)

JC-QIP81-90024 REV. 004 6.25 Reset Point Evaluation The pickup (reset) point of the undervoltage relays should be such that under the worst case transient conditions the b~s is not spuriously segregated from the off site source.

As stated previously, with 0.975 Per-Unit switchyard driving voltage, the lowest transient voltage on the Division III 4160V bus has been calculated to be 3359.2V (95.80V on a 120V basis) which occurs during the start of the HPCS pump, with voltage recovery to 3880.9 V (110.88V on a 120V basis). This condition provides an initial terminal voltage at the HPCS pump motor of 3329.25 V. Assuming a constant terminal voltage of3329.25 V (i.e. no voltage recovery as the motor accelerates) the acceleration time of the HPCS pump motor has been determined to be no more than 3.28 seconds. Therefore, the actual recovery time to at least 3880.9 V would be no more than 3.28 seconds (the Lower Analytic Limit of the time delay setting).

The present pickup (reset) point for the under voltage relays is 105.65 V and the dropout (trip) point is established by the 990/0 tap setting at 104.60V. Assuming worst case performance of the relays, the trip could occur at 104.6 V + TLU = 106:46 V and the reset could occur at 107.52V (i.e. 1.01 x 106.46).

Given the above, the bus voltage would recover above the reset point of the relay 107.52 V (3763.2 V) to at least 110.88 V (3880.9 V) before the time delay times out (even with the worst case performance from the time delay). Therefore, the reset value will prevent spurious segregation from the preferred off site source and is acceptable.

8.0 CONCLUSION

Voltage Trip:

The calculated setpoint range and the Upper Allowable Value are conservative with respect to the existing plant settings. The existing Lower Allowable Value (101.67 V) is non-conservative with respect to the calculated value. A new AV of 103 V is proposed.

Time Delay - LOCA The existing plant setpoint was shown to be acceptable. The existing Allowable Value (3.6 seconds) is non-conservative with respect to the calculated Lower Allowable Value for the LOCA Time Delay. A new AV of3.68 seconds is proposed Time Delay - No LOCA The calculated setpoint and allowable values are conservative with respect to the existing plant setpoints and allowable values.

The spurious trip and LER avoidance criterion is met for all values except the time delay lower allowable value. LER avoidance is only slightly below 90% for the recommended lower allowable value.

Page 10 INTRODUCTION These instruct.ions contain the information reqt,Jired to properly install, operate. and test certain single-phase undervoltage relays type 27N. catalog series 211T and 411T:

and overvoltage relaY5, type 59N, catalog series 211U and 411U.

The relay is housed in a case suitable for conventional semiflush oanel mounting.

All connectior's to the relay are made at the rear of the case and are clearly numbered. Relays of the 411T. and 411U catalog series are similar to relays of the 211T, and 211U series. Both series provide ~he same basic functions and are of totally drawout construction; however, the 411T and 411U series relays provide integral test facilities. Also. sequenced disconnects on the 410 series prevent nuisance operation during withdrawal or insertion of the relay if the normally-open contacts are used in the application.

Basic settings are made on the front panel of the relay. behind a removable clear clastic cover. Additional adjustment is provided by means of calibration potentio-meters inside the relay on the circuit board. 'The target is reset by means of a pushbutton extending through the relay cover.

PRECAUTIONS The following precautions uhould be taken When apPlying these relayu:

1. Incorrect wiring may result in damage. Be sure wiring a9~ees w1th the co~nection diagram for the particular ra*lay before energizing.

2. Apply only the rated control voltage marked on the relay front panel. The proper polarity must be observed when the de control power connections are made.

3. For relays with dual-rated control voltage, withdraw the relay from the case and check that.. the movable link on t.he pr*inted circuit board is in the correct posit.*jon for the system control voltage.

4. High voltage insulation test.s an! not recommended. See the section on testing for additional information.

S. The entire circuit assembly of the relay is removable. The unit should insert smoothly. Do not use excessive force.

6. Follow test instructions to verify that the relay is *in proper working order.

CAUTION: since troubleshooting entails working ",ith energized equipment. care shou1d be taken to avoid personal I$hoc:/f.. On1y compet.ant technicians Familiar ",itn good saf'ety practices should service these devices.

PlAC1NG THE RELAY INTO SERVICE

t. RECEIVING, HANDLING, STORAGE t)pon receipt of the relay (when notlncluded as part of a switchboard) examine fOr shipping damage. If damage or 10S5 is evident, file a claim at. once and promptly notify AGea Brown eoveri. use normal care in handling to avoid mechanical damage.

Keep clean and dr)l.

2. INSTALLATION Mounting:

The outlina dimensions and panel drilling and cutout inform.ation is given in Fig. 1, Connectiona:

Typica' external connections are shawn in F i gvra 2. tnternal connect ions and contact. logic are shown in Figure 3. Control power must be connect.ed in the proper polar; ty.

For relays with dual-rated control power: before energizing. withdraw the relay from its case and inspect that the movable link on the lower printed circuit board is in the correct position for the system control voltage. (For units rated 110vdc. the link should be placed in the position marKed 125voc.)

These relays have an external resistor wired to terminals 1 and 9 whiCh must be in place for normal oporntlon. n'le resistor is supplied mounted on the relay.

These relays have metal front panels which. are connected through printed circuit board runs and connector wi r i n9 to atermi na 1 at t.he rear of the r'e 1ay case. The terminal is marked -G". In all applications this termlnal should be wired to ground.

3. SETTINGS PICKUP The pickup voltage taps identify the voltage level which the relay will cause the output contacts to transfer.

DROPOUT The dropout voltage taps are identified as a percentage of the pickup voltage. Taps are pro.... ided for 7011', 80". 90X. and 9911' of pickup, or. 30". 40%. 501\. and 60" of pickup.

Note: operating voltage values other than the specific values provided by the taps can be obtained by means of an internal adjustment potentl0meter. See section on testing for setting procedure.

TIMe OIAL The time dial tapsar'e identified as '.2,3,4,5.6. Refer to thet'ime-vo'ltage charac-teristic curves in the APplicat.ion section. Tinw dial selection is not provided on relays with an Instantaneous operating characteristic. The time delay may also be

\farled from that provided bytl'le fixed tap by using the internal calibrat'lon adjust-nwnt.

4. OPERATION INDICATORS The types 27N and 59N provide a target indicator that is electronically actuated at the time the out.put contacts transfer to the trip condition. The t.arget must be manvally reset. The target can be reset only if control power-is available. AND if the input voltage to the relay returns to the '"normal" condition.

An led indicator is provided for convenience in testing and calibrating the relay and to gi .... e operating personnel infor'mation on t.he status of the relay. See Figure 4 for the operation of this indicat.or.

Units with l'l M_t." suffix on the catalog number provide a gree-n led to lndlcate the presence of control power and internal power supply volt.age.

7 Single-Phase Vol~age Relays Page 4 APPLICATION OAWA Single-phase undervoltage relays and over-voltage relays are used to provide a wide range of protective functions. including the protection of motors and generators, and to initiate bus transfer. The type 27N undervoltage relay and type 59N overvoltage relay are designed for those applications Where exceptional accuracy, repeatability, and long-term stability are reQuired.

Tolerances and repeatabi lity are given in the Ratings section. Remember that the accuracy of the pickup and dropout settings with respect to the printed dial markings is generally not. a factor, as these relays are usually calibrated in the field to ob-tain ~he particular operating value. for the application. At the time of field c~l i brat icm. the accuracy of thei nstruments used to sat the reI aye is the important factor. Multiturn internal calibr~tl0" potant1ometers provide means for accurate adjustment of the relay operating points, and allow the difference between pickup and dropout to be set as low as o.S.....

The relays are supplied with Instantaneous operating time, or with definite-time delay characteristic.

The definite-time units are offered in four time delav ranges:

0.1-1 second, 1~ 10 seconds, 2-20 seconds or 10-100 seconds.

An accur*ate peak detector is used in the types 27N and 59N. Harmonic distortion in the AC waveform can have a noticible effect on the relay operating point and on measuring instruments used to set th~ relay. An internal harmonic filter is available as an option for those applications where waveform distortion is a factor.

The harmonic filter attenuates a1l harmonics of the 50/60 HZ. input. The relay then basically operates on the fundamental component Of the lnput volt.age signal. See figure 5 for t.he typical filter response curve. To specify the harmonic filter add the suffix "-HF" to the catalog number. Note in the section on ratings that the addition of the harmonic filter does reduce somewhat the repeatability of the relay vs. temperature variation. In applications where waveform distortion is a factof', i t may be desirable to operate on the peak voltage. In these cases, the harmonic filter would oot be used.

1. MAINTENANCe ANO RENEWAL PARTS No routine maintenance is required On these relays. Follow test inst.ructions to verify that the relay is in proPer working order. We recommend that an inoperative relay be returned to the factory for repair; however, a circuit description booklet C01.4.1.7-7 which includes schematic diagrams, can be provided on request. Renewal parts will be quoted by the factory on request.

211 Series Units Drawout circuit boards of the same cat.alog number are int.erchangible. A unit is identified by t.he catalog number st.amped on the front panel and a serial number stamped on the bottom side of the drawout circuit board.

rhe board is removed by using the meta*\ pull knobs on the front panel. Removing the board ""ith the unit in service may cause an undesired operation.

An 18 point extender board (cat 200X0018) is available for use in troubleshooting and calibration of the relay.

411 Series Units Metal handles provide leverage to withdraw the relay assembly from the case. Removing the unit 1n an application that uses a normally closed contact will cause an operation. The assembly is identified by the catalog number stamped On the front panel and a serial number stamped on the bottom of the circuit board.

Test connections are reaclily made to the drawout~elay unit by using standard banana plug leads at the rear vertical circuit board. This rear board is marked for easier identification of the connection points.

Important: these relays have an external resistor mount.ed on rear terminals 1 and 9.

In order to test the drawout unit an equivVlent resistor must be connected to terminals 1 & 9 on the rear vertical circuit board of the drawout unit. The resistance value must be the same as the resistor used on the relay. A 25 or 50 watt resistor will be su~¥icient for testing. If no resistor is available. the resistor assembly mounted on t.he relay case could be removed and used. I f the resistor from the case is /.Jsed. be S/.Jre to remount it on the case at the cone 1us ion of t;es t lng.

Test Plug:

A test plug assembly, catalog number 400X0002 is available for use with the 410 series units. This device plugs into the relay case on the switchboard and allows access to all e)(ternal circuits wired to the case. See Instruction Book fa 7."7.1.'1-8 for details on the use 0' this device.

2. HIGH POTENTIAL TESTS tli gh pot-entia 1 tests are not recommended. A hi -pot test was performed at the factory before shipp; n9. If a contro 1 wl ring i nsulati on test is requ 1 red. part i all y wi thdraw the relay unit from its case sufficient to break the rear connections before applying the test voltage.

3. BUILT-IN TEST FUNCTION Be sure to take all necessary precautions i f the tests are run with the main circuit energized.

The built-in test is provided as a convenient functional test of the relay and assoC-iated circuit. When you depress the button labelled TRIP, the mea.suring and timing circuits of the relay are actuated. When the relay times out, the output contacts transfer to trip the circu1t breaker or other associated circuitry. and the target is displayed. The test button must be held down continuously until operation is obtained.

4. ACCEPTANCE TESTS Follow the teet procedures under paragraph 5. For definite-time units, select Time Dial _3. For the type 27N, check timing by dropping the voltage to 50~ of the dropout voltage set (or to zero volts i f preferred. for simplification of the test).

For the type S9N Check timing by switching the Voltage to 105~ of pid'\up (do not exceed max. input voltage rating.) Tolerances Should be within those shown on page 5.

!f the settings required for the particular application are known, use the procedures in paragraph 5 to make the final adjustments.

5. CALIBRATION TESTS L~.§;~~C9nnections anQ.. It:!st Sources; Typical test circuit connections are shown in Figure 6. Connect the relay to a proper so~rce of dc control voltage to match its nameplate rating (and internal plug setting for dual-rated units). Generally the types 27N and 59N are used in applica-tions where high accuracy is required. The ac test source must be stable and free of harmonics. A test source with 1e8$ t.hliln O.3~ harmonic distortion. such as a "line-corrector" is recommended. 00 not use a voltage source that employs a ferroresonant transformer as the stabilizing and regulating device, as these usually have high harmonic content in their output. The accuracy of the voltage measuring lnst-ruments used muat also be considered when calibrating these relays.

If the resolution of the ae test source adjustment means ,s not adequate, the arrangement using two variable transformers shown in Figure 9 to give *coarse- and

.. fine" adjustments is recommended.

When adjusting the ac test source do not exceed the maximum input voltage ratrng of the re Tay.

u..Q......l.!1Qjt;:i.!t.Q..r...;..

A light emitting diode is provided on the front panel for convenience in determining the pickup and dropout voltages. The action of the indicator d.epends on t.he voltage level and the direction of voltage change, and is best explained by referring to Figura 4.

The calibration potentiometers mentioned in the following procedures are of the multi-turn type for excellent resolution and ease of setting. For cat.alog series 211 units, the 18 point extender board provides easIer access to the calibration pots. If desired. the calibration potentiometers can be resealed with a drop of nail polish at the completion of the calibration procedure.

~.et t i"9 Pi ckU12 and Dropout Vo 1 tIt9ft~t;,

Pickup may be ~aried between the fixed taps by adjusting the pickup calibration potentiometer R27. Pickup should be set first, with the dropout tap set at 99% (60%

on "low dropo.ut units'"). Set t.he pickup tap to the nearest vahH~ to the desired setting. The callbrat.ion potentiometer has approximately a +/-.5'" range. Decrease the voltage until dropout occurs, then check pickup by increasing the voltage. ~e adjust and repeat until pickup occurs at precisely the desired voltage.

Potentiometer R1B is provided to adjust dropout. Set the dropout tap to the next lower tap to the desir-ed value. Increase t.he input voltage to above pickup, and then lower the voltage until dropout occurs. Readjust R16 and repeat until the reQuired setting has baen made.

$.~ts,t.ng,wJjJ!!L ..Qi!.J.~

Similarly, the time delay may be adjusted higher or lower than the values shown on the tiMe-voltage curves by meanS of the time delay calibration potentiometer R41. On the type 27N, time delay is initiated when the voltage drops from above the pickup value to below the dropout value. On the type 59N. timir\g is initiated when the voltage increasee from beloW dropout to above the pickup value. Referring to Fig. 4, the relay is httming out when the led indicator is lighted.
