U.S. Nuclear Regulatory Commission Page 2 March 11, 2005 The enclosures to this letter provide the requested additional information. This letter provides additional information only, and no information in the previous submittal is being revised. The proposed finding of no significant hazards considerations and environmental impact consideration as submitted in TVA's August 16, 2004, letter remain valid.

Approval of this TS change will result in ALARA and industrial safety enhancements benefiting the BFN plant staff; therefore, in the August 16, 2004, letter, TVA requested NRC approval by June 2005 to minimize the number of additional times plant personnel must perform these calibration surveillances at the current frequency. The ALARA and industrial safety implications for plant personnel remain; however, TVA recognizes that the originally requested approval date is now impractical to achieve.

Therefore, TVA requests NRC approval of TS-447 by October 2005. TVA also requests that the implementation of the revised TS be within 60 days of NRC approval.

There are no regulatory commitments associated with this submittal. If you have any questions about this change, please contact Tim Abney at (256)729-2636 or Paul Heck at (256)729-3624.

1.0 BACKGROUND

INFORMATION AND RAI

SUMMARY

TVA's August 16, 2004 letter (Reference 1) requested amendments to Operating Licenses DPR-33, DPR-52, and DPR-68 for Browns Ferry Nuclear Plant (BFN)

Units 1,2, and 3, respectively. The proposed changes would revise the operating licenses to extend the performance frequency of required calibration surveillance testing on instrumentation channels associated with high area temperature system isolation of the high pressure coolant injection (HPCI),

reactor core isolation cooling (RCIC), and reactor water clean-up (RWCU) systems. Allowable values for the trip setpoints for some of these channels would also be revised. The Technical Specifications (TS) currently require performance of these calibration activities on a more frequent interval than is technically necessary, and the performance of these calibrations on the current frequency is contrary to both ALARA principles and good industrial safety practices.

NRC's January 10, 2005 letter to TVA (Reference 2) stated that additional information was necessary to allow proper review of this request. NRC's letter, along with related telephone discussions between TVA and NRC, identified the need for additional information in five specific areas:

• Methodology used in determining the allowable values requested

• Details of the available test (surveillance) data and how they were evaluated

• Methods used in extrapolation of the available 3-month interval testing results to support 24-month testing intervals

• Reliability of the temperature loops

• Use of Instrument Society of America (ISA) 067.04 Part 2 Method 3 which is currently under discussion by NRC and the industry These areas are addressed below. Additional details are also provided on the ALARA and industrial safety benefits which result from extending the calibration intervals on the HPCI/RCIC temperature switches.

2.0 DETERMINATION OF ALLOWABLE VALUES As stated in TVA's August 16, 2004 submittal of TS-447, TVA's methods for performing scaling and setpoint calculations meet the guidance documented in NRC Generic Letter (GL) 91-04. This methodology has been reviewed by the NRC and is consistent with NRC Regulatory Guide 1.105. These calculations consider the following types of factors (1)in determining the TS allowable values utilized at BFN:

. Temperature effects

• Test equipment input

• Process instrument drift

• Radiation effects and output accuracies

• Repeatability

• Seismic effects

• Read-out accuracies (1) These factors are defined in the TVA setpoint methodology document provided as Enclosure 3.

ENCLOSURE 1 BROWNS FERRY (BFN) TS-447 REQUEST FOR ADDITIONAL INFORMATION While several factors potentially impact an instrument TS setpoint allowable value, time dependent variables are the major factor in determining the appropriate calibration intervals. Uncertainties which are time dependent will dictate how often an instrument loop must be calibrated to ensure that the loop continues to function within the analyzed limits. TVA's setpoint calculations consider any time dependent variables in the instrument measurable uncertainties. No time dependent uncertainties were identified for the HPCI or RCIC area temperature switches. Time dependent variables do exist for the RWCU area temperature instrument loops, however, analysis of the historical Unit 2 and Unit 3 operating data, taken together with the other instrument attributes that must be considered, showed that an extension of the calibration surveillance interval from the current 122 days to an interval of 24 months is acceptable.

The TVA calculations which determined the TS allowable values for the instruments impacted by TS-447 address redundant instrument channels, therefore the calculations contain much repetitive information and are quite lengthy. Representative portions of these calculations sufficient to illustrate the calculation methodology are included with this letter as Enclosure 2. Enclosure 3 provides TVA's setpoint calculation methodology document.

See Section 3.0 below for additional details on the operating data reviewed and how conclusions were drawn.

3.0 DATA EVALUATION DETAILS HPCI and RCIC area temperature switches Extensive Unit 2 and Unit 3 historical operating data for the affected instrument channels are available. Additionally, and significantly, the main steam line (MSL) temperature switches at Browns Ferry are of the same instrument type as the switches used in the HPCI and RCIC operating areas. Because their locations are inaccessible with the reactor at power, the MSL switches have always been calibrated on an 18-month or 24-month calibration interval to allow the calibrations to be performed during refueling outages. The HPCI, RCIC, and MSL temperature switch calibration data were evaluated along with vendor information and consideration of the physical attributes of the affected instrumentation. The MSL, HPCI, and RCIC data, arranged in descending length of calibration interval, are included as attachments A, B, and C, respectively, to this enclosure.

The plots on the following page show the setpoint difference scatter versus the calibration interval for the MSL, HPCI, and RCIC area temperature instruments.

It is visually apparent that the calibration interval has no significant impact on the observed setpoint difference.

ENCLOSURE I BROWNS FERRY (BFN) TS-447 REQUEST FOR ADDITIONAL INFORMATION All of the MSL, HPCI, and RCIC area temperature switch historical operating data included in Attachments A, B, and C were evaluated. Statistical analysis of the historical data showed there were no time dependent variables in the instrument measurable uncertainties. The three plots included above visually depict the fact that the setpoint deviation exhibited by these temperature switches has no significant correlation with the time interval between calibrations.

Extension of the calibration interval will have no discernible effect on the switch operating accuracy.

RWCU area temperature switches The RWCU area temperature monitoring is accomplished by resistance temperature detector (RTD) instrument loops. The RWCU data which were evaluated are tabulated in Attachment D of this enclosure. Each point provides the length of time between calibrations and the as-found setpoint difference (in percent of calibrated span) of the temperature loop trip unit.

The plot below shows the RWCU temperature loop trip unit calibration scatter versus the calibration interval from the Attachment D data. The trip setpoint drift for these RTD-based loops is not significantly affected by the length of the calibration interval.

In the case of the HPCI and RCIC area temperature instruments addressed in TVA's previous TS-447 submittal, no time dependent variables existed, therefore no actual extrapolation was necessary in determining the acceptability of the 24-month TS calibration interval. All applicable uncertainties were evaluated in E1-4

ENCLOSURE I BROWNS FERRY (BFN) TS-447 REQUEST FOR ADDITIONAL INFORMATION the determination of the TS allowable values. None of these attributes changed as a result of the TS-447 submittal, though some minor TS allowable value modifications were requested in TS-447 as refinements.

The MSL area temperature switches are already calibrated on a 24-month interval at BFN, and no negative performance trends have been observed.

These switches are essentially identical to those used in the HPCI and RCIC areas, and the operating environments are quite similar in most respects, though the MSL switches are installed in a generally more harsh physical environment.

As previously stated, the RWCU area temperature monitoring on Unit 2 and Unit 3 (1)is not accomplished by the use of bimetallic temperature switches, but rather through the use of RTDs which provide an input to rack-mounted analog trip system master trip units. Similar trip units are used widely in safety-related applications at BFN, and essentially all such loops are already calibrated on 24-month intervals. The calibration time-drift component is therefore well established, and BFN has observed no negative performance trends on any analog trip system loops. Insummary, for the RWCU area temperature instruments, minor time dependent variables do exist, they are contained within the vendor's supplied repeatability accuracy value, and they are addressed in the setpoint calculations.

Refer to Enclosure 2 for additional information on how the time dependent variables are addressed within the setpoint calculations for the RWCU area temperature instrumentation. Refer to Enclosure 3 for the document which controls TVA's setpoint calculation methodology.

(1)- Unit I will have similar RTD-based loops installed prior to its restart 5.0 TEMPERATURE INSTRUMENT LOOP RELIABILITY As discussed above, BFN has identified no negative performance trend with either the bimetallic temperature switches in use in the MSL, HPCI, and RCIC areas, nor on the RTD-based, rack mounted temperature loops primarily used in the RWCU areas. Additionally, instruments of both types are utilized for TS functions currently calibrated on 24-month intervals. No failure trend has been observed, and likewise no calibration-drift problems have been identified.

6.0 ISA 067.04 PART 2 METHOD 3 APPLICATION In a discussion with the NRC staff on February 1, 2005, TVA and NRC agreed to defer any responses concerning the use of Method 3 pending resolution of this issue with the industry. It is TVA's understanding that the NRC plans to resolve this issue with the industry by the end of March, 2005. The resolution as reached on the issue as a whole will then be applied to TS-447 as appropriate.

ENCLOSURE 1 BROWNS FERRY (BFN) TS-447 REQUEST FOR ADDITIONAL INFORMATION 7.0 ADDITIONAL INFORMATION RELATED TO ALARA AND INDUSTRIAL SAFETY CONSIDERATIONS In order to accomplish the required TS calibration function for the HPCI and RCIC area temperature instrumentation, personnel must access plant locations which involve fall hazards, high ambient temperatures, and radiation dose rates which are elevated relative to the general plant areas. Performing such work more frequently than is technically necessary is contrary to both ALARA principles and good industrial safety practices. Further information on these subjects is provided below.

ALARA The purpose of the HPCI and RCIC area temperature switches is to provide a diverse means of identifying a leak in the high-energy steam lines which provide motive power to the HPCI and RCIC turbines. These switches are necessarily located in plant overhead areas distributed along the routes of the monitored system steam supply lines and near the system turbines. In order to comply with the TS requirement for switch calibration, on a nominal 92-day frequency, plant personnel must access these switches and physically replace them with identical switches which have been calibrated using measuring and test equipment available in the plant instrument maintenance shop. The removed switches are then returned to the shop for determination of their as-found actuation setpoint.

Given that the switches are located near the systems' steam supply lines, the general area radiation fields in the vicinity of the switches are higher relative to other plant operating areas. The work involved in accessing the.switches, removing the old ones, installing the newly calibrated ones, and then leaving the area unavoidably involves the accrual of occupational radiation dose to the plant workers involved which would otherwise be avoided. Over the past 26 months, BFN personnel working on Unit 2 and Unit 3 have accrued approximately 4.4 man-REM of exposure performing these activities. Approval of the requested calibration frequency extension (from 3-months to 24-months) could therefore be reasonably expected to reduce the exposure by a corresponding factor, for a savings of approximately 3.85 man-REM over about two years of two-unit operation. This is approximately 1 man-REM/unit/calendar year. With the planned restart of Unit 1 in the spring of 2007, it is expected that similar exposure for the same work on Unit 1 could also be avoided. It should be noted that an accepted industry standard for occupational dose at boiling water reactor units is 120 man-REM/year/unit. Therefore, the anticipated occupational dose savings from reducing the performance frequency of this one set of plant maintenance activities as requested by TS-447 approaches I % of each unit's entire yearly occupational dose goal.

E1-6

ENCLOSURE 1 BROWNS FERRY (BFN) TS-447 REQUEST FOR ADDITIONAL INFORMATION INDUSTRIAL SAFETY As stated above, the HPCI and RCIC area temperature switches are installed in plant overhead locations. These locations are most often accessed by plant ladders, and the work must then be performed from platforms in many cases located 30 feet or higher above the floor elevations. In addition to the relatively higher radiation fields in these locations, these locations also have relatively high ambient temperatures. Accessing the switches at these heights is physically demanding, and working in the higher ambient temperature is also physically stressful. Thorough planning and preparation can reduce employee risk due to this work, but such efforts cannot eliminate all such risk. By extending the calibration frequency required by the TS, the number of times plant employees must place themselves in this increased-risk situation is correspondingly reduced. The two pictures below help illustrate the heights which must be negotiated in accomplishing these calibration activities.

I A study was done to evaluate the periodicity for calibration for the Penwal (bi-metallic)

Temperature Switches currently used for isolation of the HPCI and RCIC Steam Isolation Valves, and justify extending the calculation frequency for the HPCI/RCIC switches (Attachments 01). Tech Specs require the HPCI and RCIC temperature switches be calibrated every quarter, but the MSL ones are calibrated every 24 months. Both the HPCI/RCIC and MSL are Fenwal bimetallic temperature switches, the HPCI/RCIC switches are normally open and the MSL switches are normally closed.

Data was gathered for HPCI, RCIC, and MS system "as-found" and "as-left" settings as shown in attachment 01. A sample of 1280 data points was taken for HPCI / RCIC system and 195 data points were taken for MS system. After eliminating all data outliers (95% confidence band), the variance test concluded that the variance in drift for the HPCI/RCIC temperature switches are with a 95% confidence band.

As per Analysis in attachment 01 conclusion, the HPCI-RCIC data deviation is normally distributed with a mean of -0.05 and a standard deviation of 3.84. This population has a high number of samples and from reference 32, 1.96 is taken as the multiplier. Therefore the inaccuracy will be Re (Bias) = - 0.05 degree F =- 0.03 % of SP = Negligible Re (Random) = 3.84 x 1.96 =7.5 deree F = 5.1 % of SP 2 As per the analysis given in attachment 01, there isno relationship between drift and the time between calibrations. Main steam line switches were calibrated every 24 months, and do not show any drift during this period. HPCIIRCIC switches are calibrated every 3 months and do not show any drift for that period. Therefore this analysis in attachment 01, justifies extending the calibration frequency of the HPCI/ RCIC switches from 3 months to 24 months and the drift over the period of 24 months for the Penwal / EGS temperature switches are not applicable.

3 Per analysis in attachment 01, the repeatability calculated includes the temperature effect, if there is any. Normally for a temperature measuring instrument, the temperature effect is not applicable. Therefore TNe = NIA 4 The Span Error Correction uncertainty (SECu) and Static Pressure effect (SPEe) is not applicable for this switch SECu = SPEe = N/A 5 Per analysis in attachment 01, the repeatability calculated includes the normal radiation effect.

Therefore RNDe = 7ncluded in Re 6 Per reference 3, the acceptance band should be equal to or greater than the reference accuracy.

The repeatability calculated above includes drift, temperature effect, normal radiation effect and all calibration instrument errors. Field data and past calibration history shows that this switch can be calibrated to an acceptable as found value of +/- 2 degree P. Therefore Ab =;i 2 degree F =+/- 1.4% SP 7 Per Reference 36, the M&TE accuracies should be at least equal to the instrument acceptance band (Ab).

OCTe = OCRe = N/A 9 This device does not have an indicator. Therefore, INDRe = N/A 10 The pressure switch does not have any process error, water leg error or insulation resistance error. Therefore:

WLe = PRCSe = lRe = N/A 11 The basis of the accuracy calculation program is that no two transients, accidents of special events are considered to occur simltaneously. This was well documented in revisions 0, 1, and 2 of design criteria BFN-50-735. This criteria has now been voided. The calculation that has replaced it does not explicitly state this basis but only implies it. Fortunately, work for the A-46 program on seismic qualifications which have been approved by the NRC (References 42 and

43) states in section 3.2.5 "No concurrent or sequential potential events are postulated to occur other that a design basis safe shutdown earthquake (SSE) and loss of offsite power. For R9 example, no loss of coolant accidents (LOCAs), high energy line breaks (HELBs), fires, flooding, extreme winds and tornados, lightning, sabotage, etc., are postulated to occur" Therefore, no other event other than the HELB will be considered.

Although values vary in the tables, based on the following conclusions, RADe will be considered negligible.

• All inaccuracies between the pre and post radiation exposure with the exception of sample # 10 (5.7% of SP) in the Wyle Report are within the repeatability of the switch (note 1, 5.1 % of SP). R9

• The operation of these temperature switches is a function of the expansion and contraction of the metallic spring portions of these switches (Attachment 2). Metals are not affected by radiation except at verybigh levels.

Therefore accident radiation effects are considered negligible.

RADe = Negligible 13 These temperature switches are designed to be used in temperature ranges from-10O Deg. F. to 600 Deg F. The accident temperature peak only goes to 315 Deg F. Therefore:

BFN Setpoint and Scaling Calculation ED-Q0999-880554 6.0 Computations and Analyses: (Continued) 6.2 Temperature Switch Accuracy: (Continued) 6.2.1 The Allowable values:

6.2.1.1 Plant Operations Parameters Allowable Value (AV) Calculation Method 3 (Ref. 41)

Trip Setpoint: SP = UAL - Adbe For RCIC and torus area HPCI: SP = 180 - 9.1 = <170.9 OF, taken as = 165 'F Per ref. 3, the allowable value is: AV = SPt Anf= > 165 + 9.1 = 174.1 'F Allowable value taken as 180 TF R9 For Comer room HPCI: SP = 200- 10.2 = <189.8 0F, taken as = 185 TF Per ref. 3, the allowable value is: AV=SP+Anf=> 185+ 10.2= 195.2 F Allowable value taken as 200 OF Cheek Calculation:

The required un-measurable error for RCIC and Torus area HPCI:

Accident accuracy = 0% = O0 F Available un-measurable AL-AV =180- 180 = 0 0F IR9 The required un-measurable errorfor Corner room area HPCI:

Accident accuracy = 0% = OF Available un-measurable AL-AV =200-200 = OF lR9 The check calculation provides enough allowance for all the unnmasurable errors. This accounts fully for accident conditions. Hence the calculated Setpoint and allowable values are acceptable. This is concurred by Mechanical Engineering department. Seismic inaccuracy is not lIR9 evaluated; therefore the switches will require calibration after a seismic event.

Statistical comparison on HPCI, RCIC, and MSL temperature switch operational performance history Analysis of the raw data to determine if the three data sets (HPCL RCIC, MSL) can be combined into a single dataset is accomplished by first calculating the Mean, Standard Deviation, and count of each dataset and then performing a NULL-Hypothesis test of the variances with the NULL-Hypothesis assumption that the variances are equal.

The first attempt of combining the data was to test each dataset against ALL the other datasets combined.

If the calculated test variable F is larger than the F-distribution value then the CD NULL-Hypothesis must be rejected (in our case we assume that the two data sets are from the same population; thus, rejecting the Null-Hypothesis means the data can not be combined).

Statistical comparison on HPCI, RCIC, and MSL temperature switch operational performance history As cant be seen from the preceding table the MSL data calculates an F test value of 2.02 which exceeds the F-distribution threshold value; therefore, the Null-Hypothesis is rejected and it is concluded that the variance of the MSL data is statistically different from the HPCI Data. The comparison of the HPCI vs RCIC data shows that the test F value is not greater than the F distribution threshold data; therefore, it Is concluded that the HPCI and RCIC data Is from the same population and can be combined, Since the caveat that the variances of two datasets be the same prior to comparing means has been established for the HPCI and RCIC data sets then a T-test of the two means can be performed. The T test statistic is called z and Is calculated as follows (x is mean, n is count, and sigma is standard deviation, delta is assumed 0):

Examination of the graphs for the MSL data shows no apparent relationship of deviation versus time. Since the construction of all the devices is the same it is concluded that they will all exhibit the same lack of drift over the longer times.

8.3 HYPOTIIESES CONCERNING TWO v *U kt Vw VARIANCES The to-sampie r test for the dffferetce between two mealig. described in Section 7.5. requires the assumption'that the population variaces arc equal. Before procueding with this test, therefore, it -would be desirable to put this assumption to a test, In tOis section we shall describe a test of the null hypothesis HO: U? = oa against an appropriate alternative, which applies to Independent random samples from two normal populations. As we shall discover in Chapter 12, the test has many other important applica-tions.

If independent random samples of size unand n2 are taken from normal populations having the same variance, it follows from TheorTm 6.5 that the statistic F=4 .

is a value of a random vaxiab.le having the F distribution with n; - I and

- degrees of freedom. Thus, if the null hypothesis as = Lj IS true, the

-ratio of the sample variances s? and s' provides a statistic on which tests of the null hypothesis can be based.

The critical region for testing H. against the alternative hypothesis A71 > or2 is F> F., where F. is as defined on page 177, namely, it cuts off a right-band tail of area X under the Fdistribution with n, - 1 and nj - I Attachment Ha 0/

Similarly, the critical region for testing Ho against the alternative hypothesis a1 <Co is F < FE .. , and this causes some difiul-ties since Table 6 only contains values corresponding to right-hand tails of a = 0.05 and x = 0.01. As a result, we use the reciprocal of the original test statistic and make use of the relation flrst given on page 178. Thus, we base the test on the statistic F =sE1s and the critical region for testing Ho: ol = a against HI: cr2 <cr becomes F > P., where F., is the appropriate critical value of F with n2 -. 1 and j- 1 degrees of freedom.

For the two-sided alternative a'

• a' the critical region is F<F, .- 12 or F> F,2, where F -s /J52 and the degrees of freedom are n:-1 -Iand n- 1. In practice, we modify this test as in the preceding paragraph, so that we can again use the table of F values corresponding to right-hand tails of - 0.05 and M= 0.01. To this end we let sa represent the larger of the two samnple variances, s. the smaller, and we write the corresponding sample sizes as njv and n,. Thus, the test statistic becomes F = sXI1sP and the critical region is as shown in the following table:

To give an example'of a one-tail test for the equality of two variances, suppose that it islesired to determine whether Company 1 is better at plating silverwarc than Company 2. Assuming that there is essentially no difficulty in controlling the average thickness of the plating, we shall base our decision on the variability of its thickness.

To set up the test so that rejection of the null hypothesis will enable us to conclude that the plating done by Company 1 is better (less variable) than that done by Company 2, we shall have to test the null hypothesis or" against the alternative hypothesis or < al, say, at the level of signficance c -0.05. Supposing now that random samples of ize 12 of the work done by each company yields s, 0.035 mil and s2 =

0.062 mil for the thickness of the plating, we find that the appropriate test statistic has the value

(.062)3.14 (0:035)=31 Comparing this value with 2.82, the value of Fo.,D(11,11) obtained from Table 6(a) by linear interpolation,* we conclude that the null hypothesis will have to be rejected; in other words, the data support the .contentlon.that the plating done by Company 1 is less variable than that done by Company 2.

To give an example of a two-tail test for the equality of two variances, let us return to the example on page 219, where we com-pared the average heat-producing capacity of the coal from two mines.

In that example we went ahead and performed the two-sample t test even though there was a difference between the variances of the two samples. To justify this procedure, let us now test whether a' = a'4, and let us use the alternative hypothesis c2 ar, , since we are concerned only with the question whether or not these two variances are equal.

Since we had n1 5, n 6, 4s 15,750, and 5-

= 10,920 on page 219, we get F  ? 15,750 1.

Had we wanted to use the level of significance a = 0.05 or M 0.01 in hiWs example, we would have required tables of the values of F 0. 5 (v1 , a2 )

or F0,00 3(v1, v2 ); such tables may be found in the Biometrika Tables for' Startisticianslisted in. the Bibliography at the end of the book, Also, OC cumves for the various Ftests discussed in this section may be found in the book by A.

1. NOTES

1. Per Reference 19, the Master Trip Unit will exhibit a trip accuracy repeatability of l 0.75% of Span for a calibration interval of 6 months or less. The calibrated range of the subject trip unit is 4 - 20 mA which provides a span of 16 mA. The calibration data from units 2 and 3 were collected and analyzed as shown in section 5.0. It was found that there was no drift over time as seen on the graph on page 45. The regression analysis sheet on page 46 shows an R squared value of 0.00256, which means there is little or no drift in relation to time. Therefore the repeatability published by the vendor is taken as acceptable for a period of 30 months. Hence Re = i 0.0075 x (204) MA =+ 0.12 mA

= i 0.0075 x (5-1) Volt = + 0.03 V

=* 0.0075 x (200-50)° F = 1.2 0F

2. Per Ref 123, the drift is included in Re, Therefore:

De =included in Re

3. Per Reference 19, the uncertainty introduced by temperature effects on the subject switches is given by TNe = h (1.5 % Span/1001) for a 6 month calibration cycle. Per reference 9, the subject switches will experience a maximum temperature deviation of 1040 F - 60 0 F = 447F. The calibration data from units 2 and 3 were collected and analyzed as shown in section 5.0. It was found that there was no drift over time as seen on the graph on page 45. The regression analysis sheet on page 46 shows an R squared value of 0,00256, which means there is little or no drift in relation to time. The span is 4 Volt or 16 mA. Therefore the temperature effect is WNe =iO.015 x (16 MA) x (441F1100 0 F) = 0.11 mA
