SNUBBER PROGRAM PLAN AD-EG-HNP-1618 Rev. 1 Page 5 of 96 1.0 PURPOSE

1. The purpose of the Snubber program is to provide a systematic method for identification of periodic examination, testing, and service life monitoring of nuclear power plant dynamic restraints (Snubbers) and to establish the requirements for Preservice and Inservice testing, examination, and service life monitoring to assess their operational readiness. {7.1.1}, {7.1.2}

2. The Snubber program plan identifies:

Components subject to testing, examination, and monitoring

Responsibilities

Methods

Intervals

Parameters to be measured and evaluated

Criteria for evaluating the results

Corrective action

Record keeping.

2.0 SCOPE

1. These requirements apply to the ASME OM Code scope of Snubbers, which are those Snubbers used in systems that perform a specific function in shutting down a reactor to the safe shutdown condition; in maintaining the safe shutdown condition; or in mitigating the consequences of an accident.

2. For Safety or Safety Significant Snubbers, outside of the applicable Code scope above, such as any remaining ASME Code Class (1, 2, and 3) Snubbers, Snubbers which support safety related analytical boundaries, or those non-safety related Snubbers with seismic support responsibilities, these are included within the program scope.

3. In keeping with good engineering practices and to provide reasonable assurance of structural reliability, any remaining Snubbers not identified above (typically Non-Safety related) may be included in the program and at least periodically inspected or monitored.

This software program is used to organize pertinent data and records to assist with Snubber examination, testing, and service life monitoring purposes. The information contained in Snubbworks is not QA, but can be used to produce documents or lists which, when verified, can be used as QA records.

3. Examination and Test reports generated from the SnubbWorks software shall be used to document examinations and examination results, unless otherwise directed by the Program Manager. When vendor procedures are used to perform examinations and testing (such as In-Place testing of Large-Bore RCP and Steam Generator Snubbers) the vendor data sheets shall contain the Code required information for a complete examination.

4. NDE and Snubber inspection and testing personnel, performing on site work, may have their certifications and qualifications entered into IDDEAL Certworks or SnubbWorks.

5. Equipment calibration documentation shall be reviewed prior to Snubber examination and testing. Snubbworks shall be updated reflecting the current equipment identification and current due dates for calibration.

5.5 Test and Examination Scheduling

1. Test and examination scheduling routinely coincide with refueling outages.

Performing testing and examinations during refueling outages allows for improved accessibility, environmental conditions conducive for examination methods, reducing exposure (ALARA) and enhanced scheduling.

2. Examinations may be performed during plant operation (on-line) or during refueling outages, as conditions allow.

SNUBBER PROGRAM PLAN AD-EG-HNP-1618 Rev. 1 Page 13 of 96 5.5 Test and Examination Scheduling (continued)

3. Functional testing, for Test Plan credit, may be performed during plant operation (on-line) or during refueling outages, but must not start more than 60 days prior to the scheduled start of the refueling outage and must be completed prior to the start-up following the refueling outage.

5.6 Snubber Categorization

1. All of the Snubbers shall be considered one population for examination.

Alternatively, they may be categorized individually as accessible or inaccessible.

2. The decision to examine the Snubbers as one population or as separate categories shall be made and documented before the scheduled examination begins and shall not be changed during the examination. For HNP, all Snubbers are considered one population for examination.

3. When recombining categories into one population, the shorter interval of the categories shall be used.

SNUBBER PROGRAM PLAN AD-EG-HNP-1618 Rev. 1 Page 14 of 96 5.7 Visual Examination

1. Snubbers shall be visually examined on the required schedule in accordance with ASME OM and evaluated to determine their operational readiness.

Snubbers determined to be unacceptable based on the visual examination acceptance criteria at any time during the interval shall be counted in determining the subsequent examination interval. Examination intervals shall be determined in accordance with Table ISTD-4252-1 (reproduced below in Table 1, Visual Examination Intervals), unless alternative intervals are utilized per Code Case OMN-13 (as endorsed by the NRC).

Table 1, Visual Examination Intervals Number of Unacceptable Snubbers Population or Column A Column B Column C Category Size (Extended Interval) (Interval Same as Previous) (Interval Reduction to 2/3)

[Note 1] [Notes 2 and 3] [Notes 2, 4 and 5] [Notes 2, 5 and 6]

1 0 0 1 80 0 0 2 100 0 1 4 150 0 3 8 200 2 5 13 300 5 12 25 400 8 18 36 500 12 24 48 750 20 40 78 1000 29 56 109 Notes:

1. Interpolation between population or category sizes and the number of unacceptable snubbers is permissible. The next lower integer shall be used when interpolation results in a fraction.

2. The basic interval shall be the normal fuel cycle up to 24 months. The examination interval may be as great as twice, the same, or as small as fractions of the previous interval as required by the following Notes. The examination interval may vary +/-25% of the current interval.

3. If the number of unacceptable snubbers is equal to or less than the number in Column A, then the next examination interval may be increased to twice the previous examination interval, not to exceed 48 months. In that case, the next examination according to the previous interval may be skipped.

4. If the number of unacceptable snubbers exceeds the number in Column A, but is equal to or less than the number in Column B, then the next visual examination shall be conducted at the same interval as the previous interval.

5. If the number of unacceptable snubbers exceeds the number in Column B, but is equal to or less than the number in Column C, then the next examination interval shall be decreased to two-thirds of the previous examination interval or, in accordance with the interpolation between Columns B and C, in proportion to the exact number of unacceptable snubbers.

6. If the number of unacceptable snubbers exceeds the number in Column C, then the next examination interval shall be decreased to two-thirds of the previous interval.

SNUBBER PROGRAM PLAN AD-EG-HNP-1618 Rev. 1 Page 15 of 96 5.7 Visual Examination (continued)

2. Any unacceptable/unsatisfactory or degraded Snubber condition reported on the applicable inspection/test report sheet, or any noted anomaly identified during the current examination period, shall have an evaluation performed by an individual knowledgeable in Snubber operability requirements.

a. Evaluation shall be performed to determine the type and cause of the visual examination discrepancy and effect on the operability of the Snubber and related component(s).

b. If the condition is determined to be generic, then additional examinations may be required, or, if an isolated case, a Work Request may be issued to correct any discrepancies found.

c. The Program Manager or designee shall initiate a CR on any Snubber determined to be unacceptable/unsatisfactory.

3. The Visual As Found examination for Safety Related/Safety Significant Snubbers shall be performed before the Snubber is disconnected or removed for any reason. This examination is to determine that there are no visible indications of damage or impaired functional ability due to physical damage, leakage, corrosion, or degradation from environmental exposure or operating conditions.

4. As required by 10CFR50.55a(b)(3)(v)(A) all Preservice and Inservice Visual Examinations must be performed using the VT-3 visual examination method described in IWA-2213.

5. An augmented scope is invoked whenever a visual examination is to be performed as a supplemental scope, outside of the code requirements of this program.

6. Current Interval Requirements:

a. In lieu of the requirements of Table ISTD-4252-1, Snubbers are visually examined once every ten years in accordance with Code Case OMN-13.

At any point in the extended interval, if examination data results in a failure to satisfy OMN-13 requirements then the frequency of examinations shall immediately revert to the requirements of Table ISTD-4252-1.

The Safety Related/Safety Significant sample shall include representation from the DTPG based on the significant features (i.e., the various designs, configurations, operating environments, sizes, and capacities) and based on the ratio of the number of Snubbers of each significant feature, to the total number of Snubbers in the DTPG.

3. Selection of the representative Safety Related/Safety Significant Snubbers shall be random.

SNUBBER PROGRAM PLAN AD-EG-HNP-1618 Rev. 1 Page 20 of 96 5.11.1 The 10% Testing Sample Plan (continued)

4. The sample may also be selected from Safety Related/Safety Significant Snubbers concurrently scheduled for seal replacement or other similar activity related to service life monitoring. The Snubbers shall be tested on a generally rotational basis to coincide with the service life monitoring activity.

5. When additional Safety Related/Safety Significant samples are required, they shall meet the mathematical expression below.

6. The test sample plan is completed when the mathematical expression below is satisfied, or all Snubbers have been tested.

7. Testing shall satisfy the mathematical expressions as follows:

a. For each DTPG N 0.1n + C(0.1n / 2) where: N = total number of Snubbers tested that were selected from the DTPG n = number of Snubbers in the DTPG C = total number of unacceptable Snubbers found in the DTPG (excluding those counted for FMG tests)

b. For each FMG:

Nf C f (0.1n / 2) where: Nf = all Snubbers selected and tested from the FMG after the FMG was established from the DTPG Cf = total number of unacceptable Snubbers in the FMG, plus those found in the DTPG and used to establish the FMG n = number of Snubbers in the DTPG 5.11.2 The 37 Testing Sample Plan

1. An initial Safety Related/Safety Significant sample of 37 Snubbers shall be selected randomly from each Snubber plan DTPG.

2. When additional Safety Related/Safety Significant samples are required, then they shall meet the mathematical expression below.

3. The test sample plan is completed when the mathematical expression below is satisfied, or all Snubbers have been tested.

SNUBBER PROGRAM PLAN AD-EG-HNP-1618 Rev. 1 Page 21 of 96 5.11.2 The 37 Testing Sample Plan (continued)

4. Testing shall satisfy the mathematical expressions as follows:

a. For each DTPG:

N 36.49 + 18.18C where: N = total number of Snubbers tested that were selected from the DTPG C = total number of unacceptable Snubbers found in the DTPG (excluding those counted in FMG tests), plus one for each applicable FMG requiring additional tests Thus if a FMG has failures which require additional tests, regardless of the number of failures in that FMG, 'C' will only be increased only by a count of 1 for each FMG.

NOTE For each Snubber removed from 'N' and included in 'NF', another Snubber will need to be selected from the original DTPG and functionally tested for inclusion into 'N' so the mathematical expression can be satisfied.

b. For each FMG requiring additional tests NF 18.18CF where: NF = all Snubbers selected and tested AFTER the FMG was established from the DTPG CF = total number of unacceptable Snubbers in the FMG, plus those found in the DTPG and used to establish the FMG

Figure 1, 37 Test Sample Plan 5.12 Sample Expansion

1. After determination that a Safety Related/Safety Significant Snubber is unacceptable, an additional test plan sample shall be established. Failures found by the retesting conducted in Section 5.9 Step 5 do not require additional testing in accordance with Section 5.12, Sample Expansion, but shall be evaluated for appropriate corrective action.

SNUBBER PROGRAM PLAN AD-EG-HNP-1618 Rev. 1 Page 23 of 96 5.12 Sample Expansion (continued)

2. For the Safety Related/Safety Significant 10% Plan Failures - When an unacceptable Snubber has not been assigned to an FMG, the additional sample shall be taken from the DTPG. As practicable, the additional sample shall include the following:

a. Snubbers of the same manufacturer's design;

b. Snubbers immediately adjacent to those found unacceptable;

c. Snubbers from the same piping system;

d. Snubbers from other piping systems that have similar operating conditions such as temperature, humidity, vibration, and radiation; and

e. Snubbers that are previously untested.

3. For the Safety Related/Safety Significant 37 Plan Failures - Additional samples shall be selected randomly from the remaining population of the DTPG, and from untested Snubbers of the FMG as applicable.

4. In addition to the required test plan sample expansion an FMG test population may be established. The unacceptable Snubber may be categorized into a failure mode group (FMG), containing all unacceptable Snubbers that have a given failure and all other Snubbers evaluated to be subject to the same failure.

5.13 Snubber Replacement

1. Any replacement or modified Snubber(s) shall have a proven suitability for the application and environment.

2. Replacement or modified Snubbers shall be examined and tested before placing into service.

5.14 Snubber Deletion

1. Snubbers may be deleted from the plant based on analysis of the affected piping system. When an unacceptable Snubber is deleted, the deleted Snubber shall nevertheless be considered in its respective examination population, examination category, or failure mode group (FMG) for determining the corrective action.

2. The number of deleted Snubbers that failed or passed tests or examinations prior to being deleted will be used in determining examination or testing frequencies.

SNUBBER PROGRAM PLAN AD-EG-HNP-1618 Rev. 1 Page 24 of 96 5.15 Transient Dynamic Events

1. If a transient dynamic event (e.g., water hammer, steam hammer) occurs that may affect Snubber operability, then the affected Snubbers and systems shall be reviewed and any appropriate corrective action taken.

2. At a minimum, a visual examination shall be performed on all Snubbers attached to the affected sections of systems that have experienced potentially damaging transients as determined from a review of operational data.

3. In addition to satisfying the visual examination acceptance criteria of this procedure, freedom-of-motion of mechanical Snubbers shall be verified by at least one of the following methods:

a. Manually induced Snubber movement

b. Evaluation of in-place Snubber piston setting

c. Stroking the mechanical Snubber through its full range of travel

d. Functional testing of the Snubber 5.16 Service Life Monitoring

1. The object of service life monitoring is to identify service and environmental conditions that can adversely affect Snubber performance.

a. Service life varies with manufacturer recommendations, design limits, installed environmental conditions and materials, and should be adjusted based on plant experience and technical data to ensure that the Snubber(s) operational readiness is achieved throughout its intended install life.

b. Service Life Monitoring is required for all Safety Related/Safety Significant Snubbers.

c. Service Life Monitoring of Non-Safety Related Snubber is not addressed by the ASME OM Code and is at the discretion of the Program.

2. A record of the service life of each Snubber in the program shall be maintained.

a. The Snubber service life record shall include the Snubber installed location, manufacturer/model, serial number, installed date, rebuild date, and service life expiration date for each applicable Snubber.

b. When Snubbers are rebuilt or overhauled, then the service life shall be updated which will provide future statistical bases for consideration of Snubber service life.

SNUBBER PROGRAM PLAN AD-EG-HNP-1618 Rev. 1 Page 25 of 96 5.16 Service Life Monitoring (continued)

c. Initial predicted service life for all components is listed in Attachment 7, Initial Predicted Service Life.

d. Service Life listing is in Attachment 9, Safety Related/Safety Significant Snubber Listing and Attachment 10, Non-Safety Related Snubber Listing.

3. Service life for Snubbers shall be evaluated at least once each fuel cycle and adjustments made as warranted.

a. The service life shall be reviewed and necessary actions taken to ensure that the service life of all installed Snubbers will not be exceeded during the next operating cycle.

b. This evaluation can be documented in outage reports, summaries, or other methods.

4. All data from Preservice and Inservice examinations and tests, maintenance events, transient dynamic events, industry peers, manufacturers, laboratory analysis, and other service life monitoring activities will be evaluated for indications of Snubber degradation or other anomalies.

a. Results of this evaluation shall be used to identify Snubbers that are subject to degradation and to identify severe operating environments not previously identified.

b. These results may also be used to reduce or extend the service life of Snubbers or any of their subcomponents

5. If the evaluation indicates that service life will be exceeded before the next scheduled system or plant outage, then one of the following actions shall be taken:

a. The Snubber shall be replaced with a Snubber for which the service life will not be exceeded before the next scheduled system or plant outage;

b. Technical justification shall be documented for extending the service life to or beyond the next scheduled system or plant outage;

c. The Snubber shall be reconditioned such that its service life will be extended to or beyond the next scheduled system or plant outage.

6. For Mechanical Snubbers considered to be in a "harsh environment", periodic hand stroking is done in order to redistribute the grease and maintain their service life.

Rev. 1 Page 28 of 96 ATTACHMENT 1 Page 1 of 1 Visual Examination of Snubbers The following should be considered, in addition to guidance from NDEP-0613 and MMP-004, for the Visual Examination of Snubbers:

1. Per Section 5.7 Step 4, Snubber Visual Exams must be conducted using the VT-3 method, however they are conducted pin to pin only.

2. Measurement of Snubber setting:

a. As a part of any Snubber Visual Exam, the setting of the Snubber shall be measured.

b. Many Snubbers have markings on the outside to provide the general setting, however, since this is not always provided or consistent (some Snubbers at HNP have been discovered to have the scale be in metric while most are in standard units), this scale shall not be used.

c. An actual measurement (in inches) shall be taken for the setting with a scale/ruler/tape measure from the center of the "zero mark" on the Snubber. If this mark does not exist (or cannot be determined due to Snubber being turned, etc.), measure from the base of the shaft, and make a note on the Data Sheet that this was done so that Engineering can compensate for the difference in measurements.

3. Indications

a. A list of notable indications and guidance for evaluating them is included in Attachment 2, Guidance for Evaluating Visual Examination Indications.

4. Photographs

a. In order to better track the condition of Snubbers in the plant as well as make finding/examining the Snubbers easier, a photograph should be taken of each Snubber as a part of the exam.

b. The following shots should be taken:

From the ground toward the Snubber (to ease in locating it in the future)

A wide shot of the Snubber (preferably so that the setting can be seen)

A close-up of any indications/anomalies

c. These photos should be turned over to the Program Manager along with the datasheet for the exam.

5. Indications Possibly Affecting Operability

a. The Program Manager has the primary responsibility for writing condition reports when the situation requires it.

b. It is the responsibility of the examiner to provide a completed datasheet with the indication listed to the Program Manager in a timely manner so that the Program Manager can evaluate the condition

c. Should the Program Manager not be available when an indication that could affect operability is discovered (see Step 5.d), the examiner who discovered the condition will:

Initiate a CR.

Notify the control room.

Provide a completed datasheet to Engineering.

d. A condition is considered not to affect operability when it cannot be evaluated "unacceptable" per Attachment 2, meaning that "Option 3" is not listed for that particular indication.

SNUBBER PROGRAM PLAN AD-EG-HNP-1618 (PAS)

Rev. 1 Page 29 of 96 ATTACHMENT 2 Page 1 of 1 Guidance for Evaluating Visual Examination Indications The guidance listed below corresponds to the VT-3 visual examination criteria. NDEP-613 is utilized for examination methodology. Indications identified during the performance of the visual examination can be categorized into the three types of evaluations:

1. Accept As Is: Minor indications which have no impact on operability of the snubber and do not require corrective actions to be performed;

2. Evaluate Degraded: indications which require corrective measures to ensure continued operability (currently operable). Additional actions such as functional testing may be required to determine this condition;

3. Evaluate Unsat: indications which resulted in the snubber being inoperable Listed below is general guidance to determining the appropriate evaluation category. Final determination of results is at the discretion of the qualified Program Manager:

Degraded/deformed support members (1, 2 or 3)

Support structure attachments not secure (1, 2 or 3)

Shaft imperfections (1, 2 or 3)

Missing locking devices (2)

Mechanical interferences (2 or 3)

Snubber misaligned (2 or 3)

Large gaps under baseplate (1 or 2)

Spherical bearing bound/requiring lubrication (2)

Spherical bearing not properly seated (2 or 3)

Hydraulic fluid leaking from the snubber main body (2 or 3)

Hydraulic fluid leaking from the snubber fluid reservoir (2 or 3)

Hydraulic fluid weapage (2)

Snubber fluid at or below the zero mark (2 or 3)

Setting +/- thermal movement will bottom/top out Snubber (2 or 3)

The following are conditions that shall be considered non-relevant:

Fabrication marks (e.g., from punching, layout, bending, rolling, and machining);

Chipped or discolored paint;

Weld spatter on other than close tolerance machined or sliding surfaces;

Scratches and surface abrasion marks (except on hydraulic snubber piston rods);

General conditions acceptable by material, design, or construction specifications.

Rev. 1 Page 32 of 96 ATTACHMENT 5 Page 1 of 1 Mechanical Snubber Functional Test Acceptance Criteria

1. Mechanical snubbers shall be tested to verify that:

a. Activation (restraining action) is achieved within the specified range in both tension and compression.

b. Drag force of the snubber is within the specified range in both directions of travel.

c. For snubbers specifically required not to displace under continuous load, the ability of the snubber to withstand the load without displacement.

2. The Activation (Acceleration) Test Criteria is as follows:

a. Activation tests are to be performed between 10% and 100% of rated load.

b. The limiting acceleration of the snubber shall be less than or equal to 0.02g in both tension and compression. Values that exceed 0.02g may be acceptable based on analysis. Snubbers that exceed 0.02g, but are found to be acceptable will be classified as degraded and will be repaired or replaced.

3. The following table is used to determine the allowable drag forces for inservice testing of the different sizes of snubbers.

Mechanical Snubber Size and Rated Load (lbs) 1/4 1/2 1 3 10 35 100 (350) (650) (1500) (6000) (15,000) (50,000) (120,000)

Minimum Pipe Size (in.) for 1.5 2 3 6 8 24 32 3% allowable drag Notes:

1. The above table applies to ASME Class 2, 3 and ANSI B31.1 piping. Snubbers on pipe sizes other than shown above have a 2% allowable drag value.

2. Drag forces <3% of the snubber rated load is acceptable for all ASME Class 1 piping regardless of pipe size.

Any increase in drag force limits for snubbers on Class 1 systems requires approval from Westinghouse Electric Corporation.

3. Drag forces in excess of this table but <5% may be acceptable based on an analysis of piping stresses compared to ASME allowable stresses. Thermal analysis is required to increase drag forces or forces imposed on piping. Snubbers in this range shall be categorized as degraded and should be replaced or repaired as a preventive maintenance action.

4. A drag force limit of 2% of rated load shall apply to Preservice testing of new or repaired snubbers

SNUBBER PROGRAM PLAN AD-EG-HNP-1618 (PAS)

Rev. 1 Page 34 of 96 ATTACHMENT 7 Page 1 of 1 Initial Predicted Service Life

1. Initial snubber service life shall be predicted based on manufacturers recommendation and design review.

2. Actual service life determinations are made based on the effects of the environment and service conditions on the snubber service life, test and examination results and other applicable factors.

Reduced actual/expected service lives different from the initial service life listed above may be established for failed or degraded Snubbers exposed to similar environmental and service conditions as those which have been found failed or degraded may also be assigned reduced actual/expected service lives. Reduced service life snubbers may be tested or replaced at a higher frequency. Actual/expected service life may also be exended based on evaluation (i.e., seal life studies, etc.)

3. Environmental or service conditions that exceed the manufacturer's qualification basis for snubber service will be identified and evaluated per EGR-NGGC-0009.

4. The initial recommended service life of Pacific Scientific mechanical snubbers is 40 years as described in VM-NUN. These snubbers contain no parts that require periodic replacement to comply with the 40-year lifespan and no preventive maintenance is recommended or required. The initial service life is based on Pacific Scientific Standard Design Specification Report DR1319 that lists the environmental conditions to which the snubbers are qualified. Basic-PSA has since revised DR1319 stating that the service life may be extended to 60 years with appropriate maintenance and operation. Additional information is found in the "Mechanical Shock Arrestors Service Life Extension Program & Preventive Maintenance Recommendations" DR3020 on indefinitely extending the service life beyond the initial service life of 40 years.

5. The service life of the Paul Munroe/ENERTECH hydraulic snubbers is 40 years per VM-NZI. The critical components of the hydraulic snubbers are the Tefzel seals that are qualified for 40 years of service and do not require periodic replacement to maintain operability.

6. VM-NZI contains recommendations for determining fluid quality and suggests changing the fluid at 5-year intervals. The process used at HNP to determine fluid quality is to sample and analyze the fluid from each snubber when it is functional tested. If the fluid meets the criteria for used fluid per VM-NZI, then it can remain in the snubber. If the fluid does not meet the criteria, then it will be replaced or reconditioned and reused. The results of the analysis are used to trend snubber degradation. Historically, the larger particle sizes indicate snubber degradation and wear.

7. Paul Munroe Hydraulic snubber rod wiper and chevron seals on the 8", 10" and 14" bore snubbers are typically replaced at 10-year intervals. This interval is based on discussions with the vendor and the observed condition of these noncritical seals when removed. HNP has experienced no snubber failures as a result of this 10-year replacement interval. The service life of these seals is determined primarily by exposure to radiation and high temperature. The Main Steam system hydraulic snubbers at HNP are not exposed to any radiation and the Steam Generator snubbers receive relatively low levels of exposure. Temperatures in these locations are well under the design limits of the seals. Other parts including drain/fill port gaskets, fill valves, relief valves, reservoir seals, and springs are replaced as needed. Additional parts replacement is not necessary unless a problem develops.

8. Per VM-VOU, Lisega snubbers have a primary seal replacement interval of 23 years, unless a problem is observed.
