- , Significant Deviations From NUREG-1433 and Brunswick CTS. The purpose of this attachment is to identify those changes which are beyond the scope of both NUREG-1433 and the Brunswick CTS and either have or are being submitted separately from this license amendment request.
l, Evaluations Used to Justify 24-Month Surveillance Requirement Frequencies. This attachment provides a detailed description of the methodology used to justify the extension of the frequency of selected Surveillance Requirements to 24 months to support conversion of the Brunswick Plant to a 24-month fuel cycle.
As a part of the overall conversion effort, CP&L is adopting numerous new Surveillance Requirements (SRs). The new SRs are grouped into two categories (Category A and Category B SRs). Category A SRs are those SRs which are new in their entirety compared to current
)
Brunswick Plant Technical Specifications. Category B SRs are those current SRs which have been revised with ITS in some manner to be more restrictive than the current Technical Specifications require. provides a Listing of More Restrictive and New Surveillance Requirements divided into Category A and Category B types. CP&L will be reviewing each Category A and B SR to determine which will not be current upon ITS implementation, based on the projected Brunswick ITS implementation date. CP&L intends to have as many of these more restrictive surveillances current upon ITS implementation as practical; however, due to difficulties in determining the exact status of the plant and the variables associated with implementation (e.g.,
whether or not all of the more restrictive changes will be approved as currently written), CP&L proposes that the Category A changes are assumed to be performed and met, in accordance with ITS SR 3.0.1, upon implementation of the ITS. Accordingly, the initial due dato for each Category A SR will be determined based on: 1) the ITS implementation date,2) the ITS frequency of the SR and 3) SR 3.0.2. CP&L also proposes that the more restrictive Category B SRs are assumed to be performed and met, in accordance with ITS SR 3.0.1, upon implementation of the ITS. Accordingly, the due date for each Category B SR will be determined based on: 1) the last completion date of the associated CTS SR,2) the ITS frequency of the SR and 3) SR 3.0.2.
CP&L has determined that the approach discussed above will maintain compliance with the ITS and also provide the flexibility needed to implement the numerous new and more restrictive SRs which we have included as a part of our conversion to the Improved Standard Technical I
Specifications. provides the proposed changes to the Unit 2 Operating License to allow single i
recirculation loop operation. Included in this attachment is a mark-up of the Unit 2 license condition and a discussion of the change.
]
Implementation of the proposed amendments is tentatively scheduled for the fourth quarter of 1997 and is based on: 1) the training schedules for licensed and non-licensed personnel,
Document Control Desk BSEP 96-0414 / Page 3
- 2) timing of the implementation with respect to refueling outages,3) the licensed operator examination schedule,4) the time required for procedure revisions and development of new programs,5) implementation of power uprate of both units, and 6) implementation of the Long-Term Thermal Hydraulic Insh 2ility resolution at the Brunswick Plant. Brunswick Plant ITS implementation is also predicated on NRC issuance of a Safety Evaluation by July 1997, along with issuance of Safety Evaluations for the pending changes, including those changes to be submitted, which have been incorporated into the ITS (see Attachment 2). CP&L will inform the NRC staff when the ITS implementation actions are complete.
l Carolina Power & Light Company has determined that Um proposed changes do not involve a significant hazards consideration. The evaluations for making this determination are included with each specification. CP&L has also provided an environmental evaluation for each specification which demonstrates that the proposed amendments meet the eligibility for categorical exclusion set forth in 10 CFR 51.22(c)(9). Therefore, pursuant to 10 CFR 51.22(b),
an environmental assessment of the proposed changes is not required.
Carolina Power & Light Company is providing, in accordance with 10 CFR 50.91(b), Mr. Dayne l
H. Brown of the State of North Carolina with a copy of the proposed license amendments.

Each Chapter /Section in a volume is organized as follows:
l Tab. Brunswick Unit 1 Imoroved Technical Soecifications This tab contains the proposed Brunswick Unit 1 Improved Technical Specifications.
l Tab: Danswick Unit 1 Imoroved Technical Soecification Bases (as aoolicable)
This tat, contains the proposed Brunswick Unit 1 Improved Technical Specification Bases.
Tab: Brunswick Unit 2 Imoroved Technical Soecifications This tab contains the proposed Brunswick Unit 2 Improved Technical Specifications.
Tab: Brunswick Unit 2 tmoroved Technical Soecifications Bases (as acolicable)
This tab contains the proposed Brunswick Unit 2 Improved Technical Specification Bases.
Tab : Markuo of Brunswick Unit 1 and Unit 2 Current Technical Soecifications and Discussion of Chanaes Beina Made to the Brunswick CTS This tab contains a copy of the Brunswick Unit 1 and Unit 2 CTS pages annotated to provide a cross-reference to the equivalent Brunswick ITS requirement, showing the disposition of the existing requirements into the Brunswick ITS.
The annotated copy of the Brunswick CTS pages are marked with sequentially numbered
" clouds" which provide a cross-reference to a Discussion of Changes (DOCS) between the Brunswick CTS and the Brunswick ITS. The ITS number is noted on the top right corner of each CTS page, identifying the ITS LCO where the CTS requirement is located.
Items on the CTS page that are located in one or more ITS locations or sections have the A1-2
appropriate location (s) noted adjacent to the items. When the ITS requirement differs from the CTS requirement, the CTS being revised is annotated with an alpha-numeric designator. This designator relates to the appropriate DOC. Each DOC provides a justification for the proposed change. The DOC for each ITS section immediately follows the marked up CTS pages. The alpha-numeric designator also relates the proposed change to the applicable No Significant Hazards Eduation (NSHE). An Environmental Assessment is also provided for each specification.
The alpha-numeric designator is based on the category of th6 sange and a sequential number within that category. The changes to the Brunswick CT3 are categorized =
follows:
A ADMINISTRATIVE - associated with restructuring, interpretation, and complex rearranging of requirements, and other changes not substantially revising an existing requirement. There is a single No Significant Hazards Evaluation (NSHE) for this category.
M TECHNICAL CHANGES - MORE RESTRICTIVE - changes to the CTS Deing proposed in converting to the ITS, resulting in added restrictions or eliminating flexibility. There is a single NSHE for this category.
L TECHNICAL CHANGES - LESS RESTRICTIVE - changes where requirements are relaxed, relocated, eliminated, or new flexibility is provided.
There are two groups of changes " Generic" and " Specific"in this category.
Each " Specific" LESS RESTRICTIVE change has a corresponding unique No Significant Hazards Evaluation (NSHE). The " Generic" LESS RESTRICTIVE changes are subdivided into 6 subcategories, each of which is identified uniquely as either LA, LB, LC, LD, LE, or LF changes. Each subcategory of
" Generic" LESS RESTRICTIVE change is justified by a single NSHE. The subcategories and their designation are as follows:
The "LA" changes consist of relocation of details out of the CTS and into the Bases, UFSAR, QA Manual, procedures, or other plant controlled documents. Typically, this involves details of system design and function or procedural details on methods of conducting a surveillance.
The "LB" changes are related to the extension of an instrument Completion Time or Surveillance Frequency in accordance with NRC approved vendor topical reports.
The "LC" changes reflect elimination of various instrumentation requirements, where the instrument is an alarm or an indication-only instrument function that does not otherwise meet the NRC Technical Specification selection criteria.
The "LD" changes reflect extension of the refueling outage surveillance interval from 18 months to 24 months for surveillances other than Channel Calibrations.
A1-3
The "LE" changes reflect extension of the refueling outage surveillance interval from 18 months to 24 months for Channel Calibration surveillances.
The "LF" changes reflect modifying the instrumentation Allowable Values to be consistent with the current calculations performed in accordance with the plant specific setpoint methodology.
R RELOCATED - specific requirements that do not meet the NRC Technical Specification selection criteria. These items are being relocated to other plant documents as part of the conversion to ITS. There is a single NSHE for this category.
Tab: Markuo of NUREG-1433. Revision 1 Technical Soecifications and Justifications for Deviations This tab contains a copy of NUREG-1433, Revision 1, Technical Specifications which have been annotated to indicate deviations between the NUREG (as modified by generic changes identified in Attachment 2 of this letter) and the proposed Brunswick ITS.
Justifications for each of the deviations are provided with the individual ITS Chapters / Sections. The annotated copy of NUREG-1433, Revision 1, and the discussion of the deviations are cross-referenced by " clouds" which are numbered sequentially for each Chapter /Section.
Each line item in the annotated copy of NUREG-1433, Revision 1, Technical Specifications contains a cross-reference to the equivalent Brunswick CTS requirem+nt and/or discussion of change, as appropriate. This cross-reference is intended to p. wide reviewers with a quick reference to the equivalent CTS section.

The annotated copy of NUREG-1433, Revision 1, and the discussion of the deviations are cross-referenced by " clouds" which are numbered sequentially for each Chapter /Section.
l Tab: No Sianificant Hazards Evaluations l
This tab contains the required 10 CFR 50.92 No Significant Hazards Evaluations i
(NSHEs) for the proposed changes and demonstrates that the changes associated with the corresponding ITS section do not constitute a significant hazard consideration. As described for the DOC, the NSHEs are categorized as Administrative, Relocated, More Restrictive, Less Restrictive - Generic, and Less Restrictive - Specific, and are identified by an alpha-numeric designator relating the marked-up CTS and the DOC to the 1
applicable NSHE.

JUSTIFICATION OF 24-MONTH SURVEILLANCE REQUIREMENT FREQUENCIES i
i I.
PURPOSE:
j To accommodate a planned change to a 24 Month Fuel Cycle for the Brunswick Nuclear i
Units 1 and 2, Carolina Power & Light (CP&L) is integrating the necessary changes to the BNP Units 1 and 2 Technical Specifications into the documents being used to convert to l
NUREG 1433, Standard Technical Specification for General Electric BWR 4. To facilitate j
the review of the 24 Month Fuel Cycle portion of this submittal, the following overview document is being provided to identify the scope of changes and the methodology used 2
to justify the changes.
The proposed Technical Specification changes were evaluated in accordance with the guidance provided in NRC Generic Letter No. 91-04, " Changes in Technical Specification Surveillance Intervals to Accommodate a 24 Month Fuel Cycle," dated April 2,1991.
11.
SCOPE:
i The 24 Month Fuel Cycle portion of this submittal includes a justification, when the SR I
Frequency is being changed, for all existing BNP Current Technical Specification (CTS)
Surveillance Requirements (SRs) that are being retained in the BNP Improved Technical Specifications (ITS) which have a BNP CTS Frequency of 18 months. In addition, some instrument's which are currently being calibrated on a quarterly basis are also being extended to a 24 month Channel Calibration Frequency using this same methodology.
4 These changes have been divided into two categories. The categories are: (1) changes involving the Channel Calibration Frequency identified as " Instrumentation Changes" (identified in the ITS Conversion document discussion of changes as "LEs"), and (2) other changes identified as "Non-Instrumentation Changes" (identified in the ITS Conversion document discussion of changes as "LDs").
Ill.
METHODOLOGY:
1 L
in Generic Letter 91-04, dated April 2,1991, the Nuclear Regulatory Commission (NRC) provides generic guidance for evaluating going to a 24 Month Surveillance Test Interval for Technical Specification SRs. Generic Letter 91-04 specifies the steps for the evaluation needed to justify a 24 month surveillance interval. The following defines each step outlined by the NRC and provides a description of the methodology used by CP&L to complete the evaluation for each specific Technical Specification SR line itam.
I 1
A4-1
+
A.
Non-Instrumentation (LDs):
Generic Letter 91-04 identifies three steps to evaluate Non-Instrumentation:
STEP 1:
" licensees should evaluate the effect on safety of the change in surveillance intervals to accommodate a 24 month fuel cycle."
CP&L EVALUATION CP&L has evaluated each SR being changed. This evaluation provides a specific justification for each BNP CTS non-instrumentation SR which is being retained in BNP -
ITS. The evaluation is summarized in the discussion of change identified as "LDs". The following information provides a description of the purpose of surveillance testing and a general description of the methodology utilized.
The purpose of surveillance testing is to verify through the performance of the specified SRs that the tested Technical Specification Function / Feature will perform as assumed in the associated safety analysis or in accordance with the associated Function's design.
By periodically testing the Technical Specification Function / Feature, the availability of the associated Function / Feature is confirmed. As such, with the extension of BNP's operating cycle and the associated extension of the refueling cycle surveillance test interval (Frequency), a longer period of time will exist between performances of the surveillance test. If a failure resulting in the loss of a Safety Function occurs during the operating cycle and that failure would be detected only by the performance of the periodic Technical Specification SR, then the increase in the surveillance testing interval would result in a decrease in the associated Function's availability and thus have a potential impact on safety.
CP&L evaluated each associated SR to demonstrate that the potentialimpact, if any, on availability is small as a result of the change to a 24 month Frequency. The evaluations were based on the fact that the Function / Feature is tested on a more frequent basis during the operating cyclo (e.g., functionally tested quarterly), is designed to be single failure proof, or is highly reliable.
STEP 2
" Licensees should confirm that historical maintenance and surveillance data do not invalidate this conclusion".
CP&L EVALUATION CP&L has evaluated the surveillance test history of the affected SRs. This evaluation consisted of a review of the surveillance test results. Only SR test failures were evaluated because failures detected by other plant activities such as Preventative Maintenance Tasks or Surveillance Tests that are more frequent than 18 months were assumed to continue to detect failures. This review of surveillance test history validated the conclusion that the impact, if any, on system availability will be small as a result of the change to a 24 Month Fuel Cycle.
A4-2
STEP 3
" Licensees should confirm that the performance of surveillance's at the bounding surveillance intervallimit provided to accommodate a 24-month fuel cycle would not invalidate any assumption in the plant licensing basis."
CP&L EVALUATION As part of the evaluation of each SR, CP&L reviewed the impact of these changes against assumptions in BNP licensing basis. In general, these changes have no impact on the plant licensing basis. However, in some cases, the change may require a change to commitments described in the BNP Updated Final Safety Analysis Report (UFSAR). If changes were required they are identified in the associated Discussion of Changes.
B.
Instrumentation (Channel Calibrations (LEs)):
Generic Letter 91-04 identifies seven steps for the evaluation of instrumentation changes (LEs).
1 STEP 1
" Confirm that instrument drift as determined by as-found and as-left calibration data from surveillance and maintenance records has not, except on rare occasions, exceeded acceptable limits for a calibration interval."
CP&L EVALUATION CP&L evaluated the effect of longer calibration intervals on the TS instrumentation by performing a review of the surveillance test history for all instrumentation including, where necessary, instrument drift. The failure history evaluation and drift study demonstrates, except on rare occasion that, instrument drift has not exceeded the current allowable limits. In performing the drift study an effort was made to retrieve all recorded Channel Calibration data for associated instruments, when available, for the past several operating cycles. By obtaining all recorded calibration data for the past several cycles of operation, a true representation of instrument drift can be determined.
STEP 2
" Confirm that the values of drift for each instrument type (make, model, and range) and application have been determined with a high probability and a high degree of confidence. Provide a summary of the methodology and assumptions used to determine the rate of instrument drift with time based upon historical plant calibration data."
CP&L EVALUATION CP&L has performed a drift evaluation, where necessary, using calibration data obtained from surveillance tests of affected BNP ITS instrument by make, model number, and range.
The CP&L drift evaluation was performed using a computer model for drift determination A4-3 I
developed by General Electric (GE) and based on NEDC-31336, "GE instrument Setpoint Methodology". This document was submitted to the NRC, and approved.
The Boiling Water Reactor Owners' Group (BWROG) committee for Calibration interval Extension determined that the drift module of the GE Instrument Setpoint Methodology could be used to determine instrument drift for periods longer than 18 months based on actualinstrument performance in plant environments. GE, under the direction of the BWROG Calibration Interval Extension committee, developed the " General Electric 7
Instrument Trending Analysis System"(GEITAS). This quality assured program has been used to determine the drift for other plants including Limerick Generating Station and Peach Bottom Atomic Power Statien, which both received approval for the extension of Channel Calibration SRs using this program.
A copy of the verified and validated GEITAS program was obtained from GE and was used to project the thirty month drift number. The as-found and as-left data was taken i
from instrument calibration surveillance tests and was analyzed. The analysis included a review of the data points to determine any data points which would not provide a true indication of instrument drift, a change in the input / output relationship over time. If adjustments or elimination of data points were made, these changes were placed into one of the following seven (7) catemrizes: (1)" Clerical Data Entry problem" (Review identified typographical data entry enror. Data point was adjusted ta correct the error.),
(2)" Technician dats entry problem" (Review identified an obvious transposition error by the Technician entering the data. Data point was eliminated based on the data entry error.), (3)"New Instrument" (Review identified that new instrument was installed. Data point "As-found" data was zeroed because this data would not be reflective of drift. Any repetitive instrument failures would be identified in the Surveillance Test History Review.),
(4)" Chronic instrument problem" (Review of the data indicated repetitive bad data points for a single instrument with excessive changes in the input / output relationship, while all other instruments in the same application did not exhibit the same characteristics. This instrument's data was eliminated based on a unique instrument problem. Any repetitive instrument failures would be identified in the Surveillance Test History Review.), (5)"Out of Calibration Test Equipment" (Review indicated that the instrument was calibrated with an out of calibration instrumer.t. Data point was eliminated based on the fact that any recorded change could not be correlated to the performance of the instrument), (6)" Poor Calibration Methodology", (Review of the calibration methodology identified that the method of calibration would result in inconsistent and untrendable calibration results.
Data points calibrated using these techniques were eliminated based on the fact that any recorded change could not be correlated to the performance of the instrument.), and (7)" Poor Calibration Techniques", (Review identified that poor calibration techniques were used. Data point was eliminated based on the fact that any recorded change could not be correlated to the performance of the instrument.) All eliminated data points were individually evaluated and independently verified to meet these categories if they were adjusted or eliminated. Poor Calibration Methodology and Poor Calibration Techniques have been corrected through procedure revisions, training and increased supervisory over sight. The analysis produced values at intervals from one to thirty months or greater. The drift value was then compared with the drift uncertainty associated with the i
specific instrument setpoint analysis.
The results of the GEITAS evaluations showed acceptable 30 month drift values that were within setpoint analysis drift allowances in those cases where there was a sufficient A4-4
amount of historical data to satisfy the computer algorithms and the majority of the as-found and as-left values were within acceptable limits.
In some cases, a different methodology was utilized to demonstrate that the drift was acceptable. These cases included instruments that were recently installed or where the GEITAS program could not be applied. For each instrument where the GE program was not utilized to evaluate the drift data, a summary of the methodology is contained in the specific discussion of change ("LE.x").
STEP 3
" Confirm that the magnitude of instrument drift has been determined with a high probability and a high degree of confidence for a bounding calibration interval of 30 months for each instrument type (make, model number, and range) and application that performs a safety function. Provide a list of the channels by TS section that identifies these instrument applications."
CP&L EVALUATION in accordance with the methodology described in the previous section, the magnitude of instrument drift has been determined with a high degree of probability and a high degree of confidence for a bounding calibration interval of 30 months for each instrument make and model number. As required by the GEITAS software, a review was performed to ensure that there were greater than 30 data points in the data set used to perform the statistical analysis. If less than 30 data points were used in the data set, a discussion is provided in the associated discussion of change (LE.x) to provide further support for the change to a 24 month Channel Calibration frequency. The associated instruments for each affected BNP ITS SR are listed in the corresponding discussion of change ("LEs").
j STEP 4 e
" Confirm that a comparison of the projected instrument drift errors has been made with the values of drift used in the setpoint analysis. If this results in revised setpoints to i
accommodate larger drift errors, provide proposed TS changes to update trip setpoints.
if the drift errors result in revised safety analysis to support existing setpoints, provide a summary of the updated analysis conclusions to confirm that safety limits and safety analysis assumptions are not exceeded."
l CP&L EVALUATION The calculated drift value was compared to the allowances for the associated instruments as calculated in the associated setpoint analysis. Some of these analysis were completed during the performance of the 24 month drift evaluation, and therefore, data obtained from the drift study was utilized in the setpoint analysis. Changes to the setpoint values are identified as "LF" discussion of changes. If the calculated drift for an instrument fell outside the allowance for drift, the surveillance test interval was changed to a frequency which was supported by the projected drift or was extended to a 24 month Channel Calibration Frequency based on other justifications. If an instrument was not in service long euugh to establish a calculated drift number, the surveillance interval was i
extended to a 24 month interval based on other, more frequent testing or justification j
t A4-5 4

obtained from the instrument manufacturer.
STEP 5 i
" Confirm that the projected instrument errors caused by drift are acceptable for control of plant parameters to effect a safe shutdown with the associated instrumentation."
CP&L EVALUATION As discussed in the previous sections, the calculated drift values were compared to drift allowances in the setpoint analysis developed in support of the improved Technical Specification submittal. In all cases, it was found that the calculated drift fell within the assumptions of the setpoint analysis or the SR Frequency was not increased, or the SR Frequency was increased based on other justification. Therefore, in no case was it necessary to change the existing safe shutdown analysis to accommodate a larger drift error.
STEP 6
- Confirm that all conditions and assumptions of the setpoint and safety analyses have been checked and are appropriately reflected in the acceptance criteria of plant surveillance procedures for Channel Checks, Channel Functional Tests, and Channel Calibrations."
CP&L EVALUATION As part of the implementation of the improved Technical Specification project, all surveillance test procedures are being reviewed and updated to incorporate the necessary changes to the surveillance test procedures. The changes implemented as a result of the development of new setpoint analysis will also be incorporated into the surveillance procedure prior to the implementation of the improved Technical Specifications and the 24 month operating cycle surveillance test frequency.
STEP 7
- Provide a summary description of the program for monitoring and assessing the effects of increased calibration surveillance intervals on instrument drift and its effect on safety."
CP&L EVALUATION Instruments with Technical Specification calibration surveillance frequencies extended to 24 months will be monitored to identify occurrences of instruments found outside of Allowable Value. As-found and as-left calibration data will be recorded for each calibration activity. When as-found conditions are outside allowable value, an evaluation will be performed to determine if the assumptions made to extend the calibration frequency are still valid and to evaluate the effect on plant safety.
As described in the above discussion, CP&L has completed the evaluations necessary to justify a change in surveillance intervals needed to support a 24 Month Fuel Cycle, and CP&L A4-6
i' 1
l has determined that these evaluations conform to guidance provided in Generic Letter 91-04.
l The specific evaluations for each BNP CTS SR being changed is contained in the associated ITS conversion discussion of change identified as "LD.x" and "LE.x" In addition, a No l
Significant Hazards Evaluation, in accordance with 10 CFR 50.92, has been performed for the j
changes annotated as "LDs" and "LEs".

DPR-71 AND DPR-62 REQUEST FOR LICENSE AMENDMENTS CONVERSION TO IMPROVED STANDARD TECHNICAL SPECIFICATIONS Gentlemen:
In accordance with the Code of Federal Regulations, Title 10, Parts 50.90 and 2.101, Carolina Power & Light Company hereby requests a revision to the Technical Specifications for the Brunswick Steam Electric Plant (BSEP), Unit Nos.1 and 2. These proposed amendments revise the Brunswick Plant Technical Specifications to a format consistent with NUREG-1433, Revision 1, ' Standard Technical Specifications for General Electric Plants, BWR 4."
The proposed amendmeni also extends the frequency of selected Surveillance Requirements to 24 months to support conversion of the Brunswick Plant to a 24-month fuel cycle.
The detailed description and justification for the proposed Technical Specification amendment consists of 15 volumes. A detailed description of the contents and organiza! ion of the 15
)
volumes is included as Attachments 1 through 4 of this letter. These attachments include:
i, Brunswick Unit 1 and Unit 2 Improved Technical Specification (ITS)

the organization and content of each of the 15 volumes. This attachment is designed to facilitate distribution of each section within the NRC and to familiarize reviewers with the content and organization of each section., Brunswick Un t 1 and Unit 2 ITS Conversion Document Status, which describes and provides the status of pending changes, including changes to be submitted, to the Brunswick Current Technical Specifications (CTS) that are incorporated i
into this amendment request. This attachment also provides a list of the proposed generic changes to NUREG-1433, Revisions 1, that are incorporated into the Brunswick ITS amendment request. In addition, Attachment 2 includes anticipated changes to the i
Brunswick CTS that may be submitted during the course of NRC review. This information is intended to facilitate Brunswick and NRC document control during the Brunswick ITS Tel 910 457 2496 Fox 910 457 2803

A'tachment 5, Significant Deviations From NUREG-1433 and Brunswick CTS. The purpose of this attachment is to identify those changes which are beyond the scope of both NUREG-1433 and the Brunswick CTS and either have or are being submitted separately from this license amendment request., Evaluations Used to Justify 24-Month Surveillance Requirement Frequencies. This attachment provides a detailed description of the methodology used to justify the extension of the frequency of selected Surveillance Requirements to 24 months to support conversion of the Brunswick Plant to a 24-month fuel cycle.
As a part of the overall conversion effort, CP&L is adopting numerous new Surveillance Requirements (SRs). The new SRs are grouped into two categories (Category A and Category B SRs). Category A SRs are those SRs which are new in their entirety compared to current Brunswick Plant Technical Specifications. Category B SRs are those current SRs which have Deen revised with ITS in some manner to be more restrictive than the current Technical Specifications require.
1 provides a Listing of More Restrictive and New Surveillance Requirements divided into Category A and Category B types. CP&L will be reviewing each Category A and B SR to determine which will not be current upon ITS implementation, based on the projected Brunswick ITS implementation date. CP&L intends to have as many of these more restrictive surveillances current upon ITS implementation as practical; however, due to difficulties in determining the exact status of the plant and the variables associated with implementation (e.g.,
whether or not all of the more restrictive changes will be approved as currently written), CP&L proposes that the Category A changes are assumed to be performed and met, in accordance with ITS SR 3.0.1, upon implementation of the ITS. Accordingly, the initial due date for each I
Category A SR will be determined based on: 1) the ITS implementation date,2) the ITS frequency of the SR and 3) SR 3.0.2. CP&L also proposes that the more restrictive Category B SRs are assumed to be performed and met, in accordance with ITS SR 3.0.1, upon implementation of the ITS. Accordingly, the due date for each Category B SR will be l
determined based on: 1) the last completion date of the associated CTS SR,2) the ITS frequency of the SR and 3) SR 3.0.2.
CP&L has determined that the approach discussed above will maintain compliance with the ITS and also provide the flexibility needed to implement the numerous new and more restrictive SRs which we have included as a part of our conversion to the Improved Standard Technical Specifications. provides the proposed changes to the Unit 2 Operating License to allow single recirculation loop operation. Included in this attachment is a mark-up of the Unit 2 license condition and a discussion of the change.
implementation of the proposed amendments is tentatively scheduled for the fourth quarter of 1997 and is based on: 1) the training schedules for licensed and non-licensed personnel,
4 Document Control Desk BSEP 96-0414 / Page 3
- 2) timing of the implementation with respect to refueling outages,3) the licensed operator examination schedule,4) the time required for procedure revisions and development of new programs,5) implementation of power uprate of both units, and 6) implementation of the Long-Term Thermal Hydraulic Instability resolution at the Brunswick Plant. Brunswick Plant ITS implementation is also predicated on NRC issuance of a Safety Evaluation by July 1997, along with issuance of Safety Evaluations for the pending changes, including those changes to be submitted, which have been incorporated into the ITS (see Attachment 2). CP&L will inform the NRC staff when the ITS implementation actions are complete.
Carolina Power & Light Company has determined that the proposed changes do not involve a significant hazards consideration. The evaluations for making this determination are included with each specification. CP&L has also provided an environmental evaluation for each specification which demonstrates that the proposed amendments meet the eligibility for categorical exclusion set forth in 10 CFR 51.22(c)(9). Therefore, pursuant to 10 CFR 51.22(b),
an environmental assessment of the proposed changes is not required.
Carolina Power & Light Company is providing, in accordance with 10 CFR 50.91(b), Mr. Dayne H. Brown of the State of North Carolina with a copy of the proposed license amendments.

Each Chapter /Section in a volume is organized as follows:
Tab: Brunswick Unit 1 Imoroved Technical Soecifications This tab contains the proposed Brunswick Unit 1 Improved Technical Specifications.
Tab; Brunswick Unit 1 Imoroved Technical Soecification Bases (as aoolicable)
This tab contains the proposed Brunswick Unit 1 Improved Technical Specification Bases.
Tab: Brunswick Unit 2 Imoroved Technical Soecifications This tab contains the proposed Brunswick Unit 2 Improved Technical Specifications.
Tab: Brunswick Unit 2 Imoroved Technical Soecifications Bases (as aoolicable)
This tab contains the proposed Brunswick Unit 2 Improved Technical Specification Bases.
Tab : Markuo of Brunswick Unit 1 and Unit 2 Current Technical Soecifications and Discussion of Chances Beino Made to the Brunswick CTS This tab contains a copy of the Brunswick Unit 1 and Unit 2 CTS pages annotated to provide a cross-reference to the equivalent Brunswick ITS requirement, showing the disposition of the existing requirements into the Brunswick ITS.
The annotated copy of the Brunswick CTS pages are marked with sequentially numbered
" clouds" which provide a cross-reference to a Discussion of Changes (DOCS) between the Brunswick CTS and the Brunswick ITS. The ITS number is noted on the top right corner of each CTS page, identifying tb9 ITS LCO where the CTS requirement is located.
Items on the CTS page that are located in one or more ITS locations or sections have the A1-2
appropriate location (s) noted adjacent to the items. When the ITS requirement differs from the CTS requirement, the CTS being revised is annotated with an alpha-numeric designator. This designator relates to the appropriate DOC. Each DOC provides a justification for the proposed change. The DOC for each ITS section immediately folicws the marked up CTS pages. The alpha-numeric designator also relates the proposed change to the applicable No Significant Hazards Evaluation (NSHE). An Environrnental Assessment is also provided for each specification.
The alpha-numeric designator is based on the category of the change and a sequential number within that category. The changes to the Brunswick CTS are categorized as follows:
A ADMINISTRATIVE - associated with restructuring, interpretation, and complex rearranging of requirements, and other changes not substantially revising an existing requirement. There is a single No Significant Hazards Evaluation (NSHE) for this category.
M TECHNICAL CHANGES - MORE RESTRICTIVE - changes to the CTS being proposed in converting to the ITS, resulting in added restrictions or eliminating flexibility. There is a single NSHE for this category.
L TECHNICAL CHANGES - LESS RESTRlCTIVE - changes where requirements are relaxed, relocated, eliminated, or new flexibility is provided.
There are two groups of changes " Generic" and " Specific"in this category.
Each " Specific" LESS RESTRICTIVE change has a corresponding unique No Significant Hazards Evaluation (NSHE). The " Generic" LESS RESTRICTIVE changes are subdivided into 6 subcategories, each of which is identified uniquely as either LA, LB, LC, LD, LE, or LF changes. Each subcategory of
" Generic" LESS RESTRICTIVE change is justified by a single NSHE. The subcategories and their designation are as follows:
The "LA" changes consist of relocation of details out of the CTS and into the Bases, UFSAR, QA Manual, procedures, or other plant controlled documents. Typically, this involves details of system design and function or procedural details on methods of conducting a surveillance.
The "LB" changes are related to the extension of an instrument Completion Time or Surveillance Frequency in accordance with NRC approved vendor topical reports.
The "LC" changes reflect elimination of various instrumentation requirements, where the instrument is an alarm or an indication-only instrument function that does not otherwise meet the NRC Technical Specification selection criteria.
The "LD" changes reflect extension of the refueling outage surveillance interval from 18 months to 24 months for surveillances other than Channel Calibrations.
A1-3
i The "LE" changes reflect extension of the refueling outage surveillance interval from 18 months to 24 months for Channel Calibration surveillances.
l The "LF" changes reflect modifying the instrumentation Allowable Values to be consistent with the current calculations performed in accordance with the plant specific setpoint methodology.
R RELOCATED - specific requirements that do not meet the NRC Technical Specification selection criteria. These items are being relocated to other plant documents as part of the conversion to ITS. There is a single NSHE for this category.
Tab: Markuo of NUREG-1433. Revision 1 Technical Soecifications and Justifications for Qgviations This tab contains a copy of NUREG-1433, Revision 1, Technical Specifications which have been annotated to indicate deviations between the NUREG (as modified by generic changes identified in Attachment 2 of this letter) and the proposed Brunswick ITS.
Justifications for each of the deviations are provided with the individual ITS Chapters / Sections. The annotated copy of NUREG-1433, Revision 1, and the discussion of the deviations are cross-referenced by " clouds" which are numbered sequentially for each Chapter /Section.
Each line item in the annotated copy of NUREG-1433, Revision 1, Technical Specifications contains a cross-reference to the equivalent Brunswick CTS requirement and/or discussion of change, as appropriate. This cross-reference is intended to provide reviewers with a quick reference to the equivalent CTS section.
Tab: Markuo of NUREG-1433. Revision 1 Technical Soecifications Bases and Justifications for Deviations This tab contains a copy of NUREG-1433, Revision 1, Technical Specifications Bases which have been annotated to indicate deviations between the NUREG Bases (as modified by generic changes identified in Attachment 2 of this letter) and the proposed Brunswick ITS Bases. Justifications for the deviations are provided with the individual 3
ITS Chapters / Sections. The annotated copy of NUREG-1433, Revision 1, and the j
discussion of the deviations are cross-referenced by " clouds" which are numbered sequentially for each Chapter /Section.
Tab: No Sianificant Hazards Evaluations This tab contains the required 10 CFR 50.92 No Significant Hazards Evaluations (NSHEs) for the proposed changes and demonstrates that the changes associated with the corresponding ITS section do not constitute a significant hazard consideration. As described for the DOC, the NSHEs are categorized as Administrative, Relocated, More Restrictive, Less Restrictive - Generic, and Less Restrictive - Specific, and are identified by an alpha-numeric designator relating the marked-up CTS and the DOC to the
)
applicable NSHE.

PURPOSE:
To accommodate a planned change to a 24 Month Fuel Cycle for the Brunswick Nuclear Units 1 and 2, Carolina Power & Light (CP&L) is integrating the necessary changes to the BNP Units 1 and 2 Technical Specifications into the documents being used to convert to NUREG 1433, Standard Technical Specification for General Electric BWR 4. To facilitate the review of the 24 Month Fuel Cycle portion of this submittal, the following overview document is being provided to identify the scope of changes and the methodology used to justify the changes.
The proposed Technical Specification changes were evaluated in accordance with the guidance provided in NRC Generic Letter No. 91-04, " Changes in Technical Specification Surveillance Intervals to Accommodate a 24 Month Fuel Cycle," dated April 2,1991.
II.
SCOPE:
The 24 Month Fuel Cycle portion of this submittalincludes a justification, when the SR Frequency is being changed, for all existing BNP Current Technical Specification (CTS)
Surveillance Requirements (SRs) that are being retained in the BNP Improved Technical Specifications (ITS) which have a BNP CTS Frequency of 18 months. In addition, some instrument's which are currently being calibrated on a quarterly basis are a!so being extended to a 24 month Channel Calibration Frequency using this same methodology.
These changes have been divided into two categories. The categories are: (1) changes involving the Channel Calibration Frequency identified as " Instrumentation Changes" (identified in the ITS Conversion document discussion of changes as "LEs"), and (2) other changes identified as "Non-Instrumentation Changes" (identified in the ITS Conversion document discussion of changes as "LDs").
Ill.
METHODOLOGY:
In Generic Letter 91-04, dated April 2,1991, the Nuclear Regulatory Commission (NRC) provides generic guidance for evaluating going to a 24 Month Surveillance Test interval for Technical Specification SRs. Generic Letter 91-04 specifies the steps for the evaluation needed to justify a 24 month surveillance interval. The following defines each step outlined by the NRC and provides a description of the methodology used by CP&L to complete the evaluation for each specific Technical Specification SR line item.
A4-1
i l
A.
Non-Instrumentation (LDs):
Generic Letter 91-04 identifies three steps to evaluate Non-Instrumentation:
STEP 1:
t t
" licensees should evaluate the effect on safety of the change in surveillance intervals to l
accommodate a 24 month fuel cycle."
CP&L EVALUATION CP&L has evaluated each SR being changed. This evaluation provides a specific justification for each BNP CTS non-instrumentation SR which is being retained in BNP ITS. The evaluation is summarized in the discussion of change identified as "LDs". The following information provides a description of the purpose of surveillance testing and a general description of the methodology utilized.
The purpose of surveillance testing is to verify through the performance of the specified l
SRs that the tested Technical Specification Function / Feature will perform as assumed in l
the associated safety analysis or in accordance with the associated Function's design.
By periodically testing the Technical Specification Function / Feature, the availability of the associated Function / Feature is confirmed. As such, with the extension of BNP's operating cycle and the associated extension of the refueling cycle surveillance test interval (Frequency), a longer period of time will exist between performances of the surveillance test. If a failure resulting in the loss of a Safety Function occurs during the operating cycle and that failure would be detected only by the performance of the periodic Technical Specification SR, then the increase in the surveillance testing interval would result in a decrease in the associated Function's availability and thus have a potential impact on safety.
CP&L evaluated each associated SR to demonstrate that the potential impact, if any, on avaibbility is small as a result of the change to a 24 month Frequency. The evaluations were based on the fact that the Function / Feature is tested on a more frequent basis during the operating cycle (e.g., functionally tested quarterly), is designed to be single failure proof, or is highly reliable.
STEP 2
" Licensees should confirm that historical maintenance and surveillance data do not invalidate this conclusion".
CP&L EVALUATION 1
CP&L has evaluated the surveillance test history of the affected SRs. This evaluation consisted of a review of the surveillance test results. Only SR test failures were evaluated because failures detected by other plant activities such as Preventative l
Maintenance Tasks or Surveillance Tests that are more frequent than 18 months were assumed to continue to detect failures. This review of surveillance test history validated the conclusion that the impact, if any, on system availability will be small as a result of the change to a 24 Month Fuel Cycle.
A4-2
i I
i l
STEP 3
" Licensees should confirm that the performance of surveillance's at the bounding surveillance interval limit provided to accommodate a 24-month fuel cycle would not invalidate any assumption in the plant licensing basis."
CP&L EVALUATION f
As part of the evaluation of each SR, CP&L reviewed the impact of these changes against assumptions in BNP licensing basis. In general, these changes have no impact
{
on the plant licensing basis. However, in some cases, the change may require a change l
to commitments described in the BNP Updated Final Safety Analysis Report (UFSAR). If changes were required they are identified in the associated Discussion of Changes.
B.
Instrumentation (Channel Calibrations (LEs)):
Generic Letter 91-04 identifies seven steps for the evaluation of instrumentation changes j
(LEs).
1 STEP 1
' Confirm that instrument drift as determined by as-found and as-left calibration data from surveillance and maintenance records has not, except on rare occasions, exceeded acceptable limits for a calibration interval."
CP&L EVALUATION CP&L evaluated the effect of longer calibration intervals on the TS instrumentation by performing a review of the surveillance test history for all instrumentation including, where necessary, instrument drift. The failure history evaluation and drift study demonstrates, except on rare occasion that, instrument crift has not exceeded the current allowable limits. In performing the drift study an effort was made to retrieve all recorded Channel Calibration data for associated instruments, when available, for the past several operating cycles. By obtaining all recorded calibration data for the past several cycles of operation, a true representation of instrument drift can be determined.
STEP 2
- Confirm that the values of drift for each instrument type (make, model, and range) and j
application have been determined with a high probability and a high degree of confidence. Provide a summary of the methodology and assumptions used to determine the rate of instrument drift with time based upon historical plant calibration data."
CP&L EVALUATION CP&L has performed a drift evaluation, where necessary, using calibration data obtained from surveillance tests of affected BNP ITS instrument by make, model number, and range.
The CP&L drift evaluation was performed using a computer model for drift determination j
A4-3
i i
developed by General Electric (GE) and based on NEDC-31336, "GE Instrument Setpoint Methodology" This document was submitted to the NRC, and approved.
The Boiling Water Reactor Owners' Group (BWROG) committee for Calibration Interval
)
Extension determined that the drift module of the GE Instrument Setpoint Methodology could be used to determine instrument drift for periods longer than 18 months based on actualinstrument performance in plant environments. GE, under the direction of the j
BWROG Calibration Interval Extension committee, developed the " General Electric Instrument Trending Analysis System"(GEITAS). This quality assured program has been
]
used to determine the drift for other plants including Limerick Generating Station and i
Peach Bottom Atomic Power Station, which both received approval for the extension of Channel Calibration SRs using this program.
A copy of the verified and validated GEITAS program was obtained from GE and was used to project the thirty month drift number. The as-found and as-left data was taken i
from instrument calibration surveillance tests and was analyzed. The analysis included a review of the data points to determine any data points which would not provide a true indication of instrument drift, a change in the input / output relationship over time. If adjustments or elimination of data points were made, these changes were placed into one of the following seven (7) categorizes: (1)" Clerical Data Entry problem" (Review identified typographical data entry error. Data point was adjusted to correct the error.),
)
(2)" Technician data entry problem" (Review identified an obvious transposition error by the Technician entering the data. Data point was eliminated based on the data entry error.), (3)"New instrument" (Review identified that new instrument was installed. Data point "As-found" data was zerced because this data would not be reflective of drift. Any repetitive instrument failures would be identified in the Surveillance Test History Review.),
(4)" Chronic instrument problem" (Review of the data indicated repetitive bad data points for a single instrument with excessive changes in the input / output relationship, while all other instruments in the same application did not exhibit the same characteristics. This instrument's data was eliminated based on a unique instrument problem. Any repetitive instrument failures would be identified in the Surveillance Test History Review.), (5)"Out of Calibration Test Equipment" (Review indicated that the instrument was calibrated with an out of calibration instrument. Data point was eliminated based on the fact that any recorded change could not be correlated to the performance of the instrument), (6)" Poor Calibration Methodology", (Review of the calibration methodology identified that the method of calibration would result in inconsistent and untrendable calibration results.
Data points calibrated using these techniques were eliminated based on the fact that any recorded change could not be correlated to the performance of the instrument.), and (7)" Poor Calibration Techniques", (Review identified that poor calibration techniques were used. Data point was eliminated based on the fact that any recorded change could not be correlated to the performance of the instrument.) All eliminated data points were individually evaluated and independently verified to meet these categories if they were adjusted or eliminated. Poor Calibration Methodology and Poor Calibration Techniques have been corrected through procedure revisions, training and increased supervisory over sight. The analysis produced values at intervals from one to thirty months or greater. The drift value was then compared with the drift uncertainty associated with the specific instrument setpoint analysis.
The results of the GEITAS evaluations showed acceptable 30 month drift values that were within setpoint analysis drift allowances in those cases where there was a sufficient A4-4
. ~
f amount of historical data to satisfy the computer algorithms and the majority of the as-j found and as-left values were within acceptable limits.
in some cases, a different methodology was utilized to demonstrate that the drift was acceptable. These cases included instruments that were recently installed or where the GEITAS program could not be applied. For each instrument where the GE program was not utilized to evaluate the drift data, a summary of the methodology is contained in the specific discussion of change ("LE.x").
STEP 3
" Confirm that the magnitude of instrument drift has been determined with a high probability and a high degree of confidence for a bounding calibration interval of 30 months for each instrument type (make, model number, and range) and application that performs a safety function. Provide a list of the channels by TS section that identifies these instrument applications."
CP&L EVALUATION In accordance with the methodology described in the previous section, the magnitude of instrument drift has been determined with a high degree of probability and a high degree of confidence for a bounding calibration interval of 30 months for each instrument make and model number. As required by the GEITAS software, a review was performed to ensure that there were greater than 30 data points in the data set used to perform the statistical analysis. If less than 30 data points were used in the data set, a discussion is provided in the associated discussion of change (LE.x) to provide further support for the change to a 24 month Channel Calibration frequency. The associated instruments for each affected BNP ITS SR are listed in the corresponding discussion of change ("LEs").
1 STEP 4
" Confirm that a comparison of the projected instrument drift errors has been made with the values of drift used in the setpoint analysis. If this results in revised setpoints to accommodate larger drift errors, provide proposed TS changes to update trip setpoints.
If the drift errors result in revised safety analysis to support existing setpoints, provide a summary of the updated analysis conclusions to confirm that safety limits and safety i
analysis assumptions are not exceeded."
CP&L EVALUATION The calculated drift value was compared to the allowances for the associated instruments as calculated in the associated setpoint analysis. Some of these analysis were completed during the performance of the 24 month drift evaluation, and therefore, data j
obtained from the drift study was utilized in the setpoint analysis. Changes to the setpoint i
values are identified as *LF" discussion of changes. If the calculated drift for an i
instrument fell outside the allowance for drift, the surveillance test interval was changed to a frequency which was supported by the projected drift or was extended to a 24 month Channel Calibration Frequency based on other justifications. If an instrument was not in service long enough to establish a calculated drift number, the surveillance interval was extended to a 24 month interval based on other, more frequent testing or justification i
A4-5 l
- e 1
obtained from the instrument manufacturer.
STEP 5
" Confirm that the projected instrument errors caused by drift are acceptable for control of plant parameters to effect a safe shutdown with the associated instrumentation."
CP&L EVALUATION As discussed in the previous sections, the calculated drift values were compared to drift allowances in the setpoint analysis developed in support of the improved Technical Specification submittal. In all cases, it was found that the calculated drift fell within the assumptions of the setpoint analysis or the SR Frequency was not increased, or the SR Frequency was increased based on other justification. Therefore in no case was it necessary to change the existing safe shutdown analysis to accommodate a larger drift error.
STEP 6
" Confirm that all conditions and assumptions of the setpoint and safety analyses have i
been checked and are appropriately reflected in the acceptance criteria of plant surveillance procedures for Channel Checks, Channel Functional Tests, and Channel Calibrations."
CP&L EVALUATION As part of the implementation of the Improved Technical Specification project, all surveillance test procedures are being reviewed and updated to incorporate the necessary changes to the surveillance test procedures. The changes implemented as a l
result of the development of new setpoint analysis will also be incorporated into the surveillance procedure prior to the implementation of the improved Technical 5
Specifications and the 24 month operating cycle surveillance test frequency.
STEP 7
)
k
" Provide a summary description of the program for monitoring and assessing the effects of increased calibration surveillance intervals on instrument drift and its effect on safety."
CP&L EVALUATION Instruments with Technical Specification calibration surveillance frequencies extended to j
24 months will be monitored to identify occurrences of instruments found outside of Allowable Value. As-found and as-left calibration data will be recorded for each calibration activity. When as-found conditions are outside allowable value, an evaluation will be performed to determine if the assumptions made to extend the calibration frequency are still valid and to evaluate the effect on plant safety.
As described in the above discussion, CP&L has completed the evaluations necessary to justify a change in surveillance intervals needed to support a 24 Month Fuel Cycle, and CP&L A4-6 l

has determined that these evaluations conform to guidance provided in Generic Letter 91-04.

Significant Hazards Evaluation, in accordance with 10 CFR 50.92, has been performed for the i
changes annotated as "LDs" and "LEs".
