7.6 Visual Examination Program 7.6.1 Examination Requirements (Visual Inspection) - Visual examination for operational readiness is required of snubbers, with the number of snubbers and the frequency of reexamination being determined by the number of unacceptable snubbers within a group.

7.6.2 In-service Examinations Requirements

a. In-service Examination for safety-related snubbers shall be a visual examination for impaired functional ability due to physical damage, leakage, corrosion, or degradation from environmental exposure or operating conditions. The visual examination is performed in accordance with MST-100.02; additionally applicable NDE procedures shall be used for ISI Snubbers. NDE personnel shall perform PSI VT-3 exam for ISI Snubbers. The in-service examination of accessible and inaccessible snubbers is performed per work orders, additionally for ISI Snubbers for the ISI program applies.

JAF Program SEP-SNB-JAF Revision No. 0 Page 13 of 34 NOTE: Parallel and multiple installations shall be identified and counted individually.

1. Snubbers shall be installed so they are capable of restraining movement when activated. Visual observation of loose fasteners, deformed members, or detection of disconnected components requires identification. Snubbers evaluated to be incapable of restraining movement shall be classified unacceptable.
2. Snubbers shall be installed in such condition that they do not restrict the thermal movement to the extent that unacceptable overstressing could develop in the pipe or other equipment. The installation is designed to protect or restrain. IF no indication of binding, misalignment, or deformation is observed, THEN the provisions of this requirement are considered to have been satisfied.
3. Design-specific characteristics required for the actuation of the snubber shall be visually verified.
4. Fluid supply or content for hydraulic snubbers shall be observed.
5. Observation that the fluid level is equal to or greater than the minimum amount which is sufficient for actuation at its operating extension is considered to satisfy the provisions of this requirement for hydraulic snubbers.
6. If the fluid is less than the minimum amount, the installation is to be identified as unacceptable; unless a test is performed establishing that performance of the snubber is within specified limits.
7. Tests on snubbers with low fluid levels shall be performed in accordance with MST-100.01. The initial test shall start with the piston at the as-found setting and be performed in the extension (tension) direction.
8. Visual examination discrepancies which indicate potential impaired operability of the snubber(s) may be resolved in accordance with the requirements of Pre-service Examination and Operational Testing Evaluations.
9. If a snubber is scheduled for visual examination and removal for any reason (in-service testing, seal life, repairs, etc.) is required, then visual examination shall be performed before the snubber is removed.
10. Attachment 2 lists items which should be included in the examination.

7.6.3 In-service Examination Frequency

a. Examination Frequency is based on the number of inoperable snubbers from the previous inspection, and on the length of the previous interval (I). The basic interval shall be the normal fuel cycle up to 24 months. When evaluations in accordance with In-service Operational Testing Failure Evaluation reveal the existence of inoperable snubber(s),

JAF Program SEP-SNB-JAF Revision No. 0 Page 14 of 34 refer to Attachment 1 to determine future interval. ASME Code Case OMN-13 extends this interval to 10 years.

b. This examination interval may vary in time by plus or minus 25 percent to coincide with planned outages, and the new interval shall be based on the new examination results.
c. Examinations may be performed at an interval less than 75 percent of the stated interval and shall be used as a new reference point to determine the next inspection. However, those examination results shall not be used to permit a longer interval than that which applied before the examination was performed.
d. Any examination whose results require a shorter examination interval will override the previous interval.
e. The examination interval applies separately to each examination group (accessible or inaccessible).
f. The examination interval shall be controlled under the provisions of Preventive Maintenance Process in Passport.

7.6.4 In-service Examination Sample Size

a. The in-service examination sample size shall be all (100 percent) safety-related Snubbers, non-ISI and ISI, in a particular group (accessible or inaccessible).

NOTE: Fractional sample sizes shall be rounded up to the next integer.

7.6.5 In-service Examination Failure Evaluation

a. Snubbers which do not meet the examination acceptance criteria shall be evaluated to determine the cause of the unacceptable condition and documented through the Corrective Action Program.
b. Functional Test Evaluation - The snubber(s) that is found to be unacceptable as a result of in-service examination may be tested in accordance with the requirements of In-service Operational Testing Failure Evaluation provided that testing can resolve the unacceptable condition. Results which satisfy the operability test criteria may be used to disposition the snubber(s) as acceptable.

7.6.6 Visual In-service Examination Failure Mode Groups (FMGs)

Unacceptable snubbers shall be categorized into examination failure mode groups.

a. An examination failure mode group shall include all unacceptable snubbers which have a given failure and all other snubbers subject to the same failure, except as permitted to be considered separately per Snubber Categorization.

JAF Program SEP-SNB-JAF Revision No. 0 Page 15 of 34

b. The examination failure mode groups shall be distinct for examination purposes from any testing failure mode groups.
c. The following examination failure mode groups shall be used:
  • design/manufacturing
  • application induced
  • maintenance/repair/installation
  • isolated
  • unexplained
  • transient dynamic event 7.6.7 Examination Failure Mode Group Boundaries Once an examination failure mode group has been established, any snubber(s) in that group will not be part of the examination group(s) from which the snubber originated unless an evaluation shows more than one failure mode. The new examination failure mode group will remain as defined until
a. The examination failure mode group has reached the maximum time interval allowed; or
b. Replacement/modification action provides an examination failure mode group with all acceptable snubbers.

7.6.8 Snubbers in More Than One Failure Group

b. Unacceptable Snubbers in More Than One Failure Group Any snubber(s) which is included as unacceptable in more than one failure mode group shall be counted for scheduling purposes in each of these failure mode groups.

7.6.9 In-service Examination Corrective Action and Impact on Examination Frequency

a. Snubbers which have been found unacceptable by the visual acceptance criteria and have been failure evaluated shall be subject to the failure mode corrective action(s) including impact on subsequent examination schedule.
b. Design/Manufacturing, Maintenance/Repair/Installation, or Application Induced Failure Mode Group Corrective Action

JAF Program SEP-SNB-JAF Revision No. 0 Page 16 of 34

1. All snubbers in the examination failure mode group shall be replaced/modified.

The replacement/modified snubber shall be reclassified as acceptable. A Pre-Service examination shall be completed; OR

2. All unacceptable snubbers in the examination failure mode group shall be replaced or repaired to the original qualified condition and shall determine the examination schedule for this examination failure mode group in accordance with In-service Examination ISI Frequency; OR
3. All unacceptable snubbers in the APPLICATION INDUCED FAILURE MODE GROUP shall be replaced/repaired. All snubbers in this group shall be re-categorized as acceptable for examination frequency purposes, provided the environment or applications are compatible with the design parameters of the examination failure mode group snubber(s).

7.6.10 Isolated Failure Mode Corrective Action All unacceptable snubbers in this examination failure mode group shall be replaced or repaired to an acceptable condition and re-categorized as acceptable for examination frequency purposes.

7.6.11 Unexplained Failure Mode Corrective Action All unacceptable snubbers in this examination failure mode group shall be replaced/repaired to an acceptable condition and shall determine the examination schedule for this examination failure mode group.

7.6.12 Deletions of Unacceptable Snubbers Snubbers may be deleted based on analysis of the affected piping system. When unacceptable snubbers are deleted, the remaining snubbers in the examination failure mode group shall be subject to corrective action, and the number of unacceptable deleted snubbers shall also be used in determining the next examination interval.

7.6.13 Supported Component(s)/System Evaluation System(s) of which an unacceptable snubber is part shall be considered inoperable if the snubber is not returned to an acceptable condition within the time frame specified by Snubber Operability and Time Requirement for Evaluation section. An evaluation shall be performed for possible damage to the supported system or component.

JAF Program SEP-SNB-JAF Revision No. 0 Page 17 of 34 7.7 Operational Readiness Testing Program Functional Testing Requirements - Operability tests are required to be performed on representative samples of snubbers at specific intervals. For each snubber determined to be unacceptable from the operability testing, an additional sample lot of snubbers shall be tested.

NOTE: Snubber testing may begin no earlier than 60 days before a scheduled refueling outage.

7.7.1 Pre-service Operability Testing Pre-service operability testing shall be performed on all safety-related snubbers per MST-100.01 or approved vendor procedures. Testing may be at the manufacturer or another approved vendor facilities, provided the test procedure is reviewed and approved by the Snubber Program Engineer. The testing shall verify that:

a. The force that will initiate motion (breakaway force) and the force that will maintain low velocity displacement (drag force), are within specified limits in tension and compression for mechanical and hydraulic snubbers.
b. Activation is within the specified range of velocity or acceleration in tension and compression.
c. Release rate, where applicable, is within the specified range in tension and compression.

For units specifically required not to displace under continuous load, the ability of the snubber to withstand load without displacement shall be demonstrated

d. Operability Testing Loads - Snubbers shall be tested at a load sufficient to verify the operating parameters. Testing at less than rated load must be correlated to operability parameters at rated load.

NOTE: Differences may exist between installed operating conditions and conditions under which snubber is tested. In such cases, correction factors shall be established and test results shall be correlated to operating conditions, as appropriate.

e. Pre-service Operability Testing Failures -Snubbers that fail the preservice operability test shall be evaluated for the cause(s) of failure(s). If a design deficiency in the snubber is found, it shall be corrected. Modified, repaired, or replacement snubbers shall be tested per Pre-service Operability Testing requirements.

7.7.2 In-service Operability Testing In-service operability tests of safety-related snubbers shall be performed in accordance with MST-100.01 or per vendor procedure approved by the Snubber Program Engineer. Operability testing of snubbers shall be performed to verify the following:

a. The force that will initiate motion (breakaway force), and the force that will maintain low velocity displacement (drag force), is within specified limits in tension and compression.

JAF Program SEP-SNB-JAF Revision No. 0 Page 18 of 34

b. Activation is within the specified range of velocity or acceleration in tension and compression (for mechanical and hydraulic snubbers).
c. Release rate, where applicable, is within the specified range in tension and compression.

For units specifically required not to displace under continuous load, the ability of the snubber to withstand load without displacement shall be demonstrated.

d. Operability Testing Loads -Snubbers shall be tested at a load sufficient to verify the operating parameters. Testing at less than rated load must be correlated to operability parameters at rated load.

NOTE: Differences may exist between installed operating conditions and conditions under which a snubber is tested. In such cases, correction factors shall be established and test results shall be correlated to operating conditions, as appropriate.

e. In-service Operability Testing Frequency - Testing of safety-related Snubbers, ISI and non-ISI, shall take place at least every refueling outage using a sample of snubbers in the facility.

7.7.3 In-service Operability Testing Sample Plans

a. The in-service testing sample shall be selected using the 10% sample plan.
b. The testing samples for a given test interval shall be based on the following criteria:

Initial Sample Test Lots - Representative/Random Sampling for the first sample lot tested, 10% of the safety-related snubbers in the general population shall be selected. As far as practical, this sample selected for testing shall include the various designs, configurations, operating environments, range of sizes, and capacity of snubbers, etc.

The first sample lots tested shall be a composite based on the ratio of each particular category (manufacturer type) to the total number of snubbers installed in the plant.

Sample lot selection from the representative categories of snubbers shall be random.

For example: 10% of each snubber type is to be tested.

  • 12 Small Bergen-Paterson hydraulic snubbers
  • 6 Medium Bergen-Paterson hydraulic snubbers
  • 4 Large Bergen-Paterson hydraulic snubbers
  • 2 Pacific Scientific mechanical snubbers
  • 1 Lisega hydraulic snubber NOTE: Selection of Snubbers for 10% functional testing is based on location, not on snubber serial number.

JAF Program SEP-SNB-JAF Revision No. 0 Page 19 of 34

c. Additional test(s) Lots - Results of Unacceptable Snubbers in the Same Test Interval For any snubber(s) determined to be unacceptable after an engineering evaluation has been completed as a result of testing discrepancies, an additional sample of at least one-half the size of the initial sample lot for that type of snubber shall be tested until the mathematical expressions below are satisfied, or all snubbers in the Defined Test Plan Group (DTPG) or Failure Mode Group (FMG) have been tested.

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 DTPG C = total number of unacceptable snubbers found in the DTPG (excluding those counted for FMG tests)

For each FMG, NF > CF (0.1n / 2) where NF = all snubbers selected and tested from the FMG after 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 DTPG

d. Additional Test Lots Composition in the Same Test Interval. When an unacceptable snubber has not been assigned to an FMG, the additional sample shall be taken from the DTPG.
e. As far as practical, the additional samples shall include:
  • Snubbers of the same manufacturers design
  • Snubbers immediately adjacent to those found unacceptable
  • From other piping systems, snubbers that have similar operating conditions such as temperature, humidity, vibration, and radiation.
f. Subsequent Test Intervals - Sample Selection Criteria - For subsequent in-service testing intervals, each representative sample shall be selected from previously untested snubbers.

JAF Program SEP-SNB-JAF Revision No. 0 Page 20 of 34 When all snubbers have been selected for testing, then any additional required sampling lots shall be selected in accordance with above listed paragraph.

g. In-service Operability Testing Failure Evaluation Failure Evaluation Requirements - Snubbers that do not meet the operability testing acceptance criteria shall be evaluated to determine the cause of failure. A Condition Report shall be initiated to document the unacceptable condition.

7.7.4 Operational Readiness Testing Failure Mode Groups (FMGs)

Unacceptable snubbers shall be categorized into failure mode groups.

a. A test failure mode group shall include all unacceptable snubbers which have a given failure and all other snubbers subject to the same failure, except as permitted to be considered separately per Snubber Categorization.
b. The test failure mode groups shall be distinct for examination purposes from any testing failure mode groups.
c. The following test failure mode groups shall be used:
  • design/manufacturing
  • application induced
  • maintenance/repair/installation
  • isolated
  • unexplained
  • transient dynamic event 7.7.5 Test Failure Mode Group Boundaries Once an examination failure mode group has been established, any snubber(s) in that group will not be part of the test group(s) from which the snubber originated unless an evaluation shows more than one failure mode. The new test failure mode group will remain as defined until:
a. The test failure mode group has reached the maximum time interval allowed; or
b. Replacement/modification action provides a test failure mode group with all acceptable snubbers.

JAF Program SEP-SNB-JAF Revision No. 0 Page 21 of 34 7.7.6 Snubbers in More than One Failure Group

a. In the event a snubber(s) is included in more than one test failure mode group, it shall be counted in each of those FMGs and shall be included in a corrective action for each of those FMGs.
b. Unacceptable Snubbers in More than One Failure Group Any snubber(s) which is included as unacceptable in more than one failure mode group shall be counted for scheduling purposes in each of these failure mode groups.

7.7.7 Operational Readiness Testing Corrective Action and Impact on Continued Testing

a. Snubbers which have been found unacceptable by the test acceptance criteria and have been failure evaluated shall be subject to the failure mode corrective action(s) with its indicated impact on continued testing.
b. The 10% Testing Sample Plan Corrective Action from Design/Manufacturing, Maintenance/Repair/Installation, or Application Induced Failure Mode Groups:
1. All snubbers in the test failure mode group shall be replaced/modified. The replacement/modified snubber shall be reclassified as acceptable. A Pre-service examination shall be completed; OR
2. All unacceptable snubbers in the test failure mode group shall be replaced or repaired to the original qualified condition and the number of unacceptable snubber(s) shall determine the additional testing lots previously defined.; OR
3. All unacceptable snubbers in the APPLICATION INDUCED FAILURE MODE GROUP shall be replaced/repaired. Provided the environment or application and the design parameters of the test failure mode group snubber(s) are made compatible, all snubbers in this group shall be re-categorized as acceptable and the repaired/replacement snubbers are not counted for the purpose of determining the number of additional sample lots.

7.7.8 Isolated Failure Mode Corrective Action All unacceptable snubbers in this test failure mode group shall be replaced/repaired to an acceptable condition and dispositioned as acceptable, and replacement/repaired snubbers are not counted for the purpose of determining the number of additional sample lots.

JAF Program SEP-SNB-JAF Revision No. 0 Page 22 of 34 7.7.9 Unexplained Failure Mode Corrective Action All unacceptable snubbers in this test failure mode group shall be replaced/repaired to an acceptable condition. The number of unacceptable snubber(s) shall determine the additional testing lots.

7.7.10 Deletions of Unacceptable Snubbers Snubbers may be deleted based on analysis of the affected piping system. When unacceptable snubbers are deleted, the remaining snubbers in the test failure mode group shall be subject to corrective action, and the number of unacceptable deleted snubbers shall also be used in determining the next examination interval.

7.7.11 Supported Component(s)/System Evaluation System(s) of which an unacceptable snubber is part shall be considered inoperable if the snubber is not returned to an acceptable condition within the time frame specified by Snubber Operability and Time Requirement for Evaluation, (section 7.8). An evaluation shall be performed for possible damage to the supported system or component.

7.7.12 In-service Operability Testing Methods

a. Testing shall be performed on the snubbers in their as-found condition to the fullest extent practical regarding the features to be tested.
b. Test methods employed must not alter the condition of the snubber to the extent the results are not representative of the parameters prior to the test.
c. In-service operability testing may be accomplished with the snubber installed in its permanent location by using approved test methods and equipment.
d. Snubbers may be removed and bench tested in accordance with approved test procedures.

After reinstallation, the snubber shall meet the requirements of Per-service Examination Requirements.

e. Where the physical size of the snubber, test equipment limitations, or inaccessibility of location prevent the use of methods in steps C and D above, the snubber subcomponents shall be examined and tested in accordance with approved procedures. Reassembly of individual components must be in accordance with approved procedures.
f. Testing methods may be used which measure parameters indirectly or parameters other than those specified if those results can be correlated to specified parameters through established methods.

7.9.2 The designated service life for Bergen-Paterson hydraulic snubbers is 16.9 years from the date of the rebuilding of a snubber in accordance with MP-102. For new snubbers, snubbers new from the Warehouse or DTO from the manufacturer, the service life is 16.9 years from the date of the new functional test at FitzPatrick. The functional test constitutes the end of shelf life and the beginning of service life.

JAF Program SEP-SNB-JAF Revision No. 0 Page 24 of 34 EC-62220 documented the Bergen-Paterson service life evaluation done by Lake Engineering and EC-61084 concluded that extending the service life for 10 and 20KIP snubbers to 17 years is acceptable. Service life intervals for other Bergen-Paterson snubbers remain at 16.9 years.

7.9.3 The designated service life for Lisega hydraulic snubbers is 21 years.

7.9.4 The designated service life for mechanical snubbers is 40 years from the date of installation.

7.9.5 At least once per operating cycle (increased or decreased, if warranted), the installation and maintenance records for each installed snubber whose failure could adversely affect the primary coolant or other safety-related system, shall be reviewed to verify the designated service life has not been exceeded or will not be exceeded prior to the next scheduled snubber service life review. Spare snubbers, usually located in the snubber cage, shall also be reviewed to ensure they are not installed in the plant with inadequate service life remaining. This review shall be documented by a work request issued for this purpose and completed prior to startup from each refueling outage.

7.9.6 IF the indicated service life of a snubber installed in the plant will be exceeded prior to the next scheduled snubber service life review, THEN the snubber service life shall be re-evaluated or the snubber shall be replaced or refurbished, in accordance with section 7.10.3, to extend its service life beyond the date of the next scheduled service life review. This re-evaluation, refurbishment or replacement shall be indicated in the maintenance history records.

7.9.7 Periodically the snubber engineer shall re-evaluate or contract a re-evaluation of the groups and types of snubbers according to their respective environments. The re-evaluation may shorten or lengthen the service life for group(s) and/or type(s) of snubbers.

7.9.8 If testing is conducted specifically for service life monitoring purposes, the results of such testing do not require testing of additional snubbers, but shall be evaluated for appropriate corrective actions.
