Each group may be inspected independently in accordance with the above schedule.

Visaal Inspection Acceptance Criteria Visual inspections shall verify (1) that there are no visible indications of damage or impaired OPERABILITY, and (2) attachments L
to the foundation or supporting structure are secure, and (3) fasteners for attachment of the snubber to (a) the component or pipe and (b) the snubber anchorage are secure.
Snubbers which.
appear inoperable as a result of visual inspections may be determined OPERABLE for the purpose of establishing the next visual inspection interval, provided that (1) the cause of the rejection is clearly established and remedied for that particular snubber and for other snubbers that may be generically susceptible; and (2) the 2
affected snubber is functionally tested in the as found condition and determined OPERABLE per Specification 4.7.6.e or 4.7.6.f, as applicable.
However, when a fluid port of a hydraulic snubber is found to be uncovered, the snubber shall be determined inoperable and cannot be determined OPERABLE via functional testing for the purpose of establishing the next visual inspection interval. All snubbers connected to an inoperable common hydraulic fluid reservoir shall be counted as inoperable snubbers.
I "The inspection interval shall not be lengthened more than one step at a time.
- The provisions of Specification 4.0.2 are not applicable.

' Functional Tests At least once per 18 months during shutdown, a representative sample of at least 10% of the total of each type of ' snubber'in use in.the-plant shall'be functionally tested either.in place or.in a bench test.
For each snubber of a type that does not meet the functional-' test acceptance criteria of' Specification 4.7.6.e or 4.7.6.f, an additional 10% of that type of snubber shall be functionally tested until no more failures are found or until all snubbers of that type have been functionally tested.
The representative sample selected for functional testing shall include the various configurations, operating environments and the range of-size and capacity of snubbers.
At least 25% of the snubbers in the representative sample shall include snubbers from the following three categories:
1.
The first snubber away from each reactor vessel nozzle 2.
Snubbers within 5 feet of heavy equipment (valve', pump, turbine-motor,etc.)
3.
Snubbers within 10 feet of the discharge from a safety relief valve.
Snubbers that are especially difficult to remove or in high radiation zones during shutdown shall also be included in the representative sample.*
In addition to the regular sample, snubbers which failed the previous functional test shall be retested during the next test period.
If a l
spare snubber has been installed in place of a' failed snubber, then both the failed snubber (if it is repaired and installed in another position) and the spare snubber shall be ratested. Test results of those snubbers may not be included for the re-sampling.
- Permanent or other exemptions from functional testing for individual snubbers in these caterories may be granted by the Commission only if justifiable basis for exemption is presented and/or snubber life destructive testing was performed to qualify snubber operability for all design conditions at either the completion of their fabrication or at a subsequent date.

Hydraulic Snubbers Functional Test Acceptance Criteria
- The hydraulic snubber functional test shall verify that:
1.
Activation (restraining action) is achieved within the specified range of velocity or acceleration in both
. tension and compression.
2.
Snubber bleed or release rate, where required, is within the.specified range in compression or tension.
For snubbers specifically required to not displace under continuous load, the ability of the snubber to withstand load without displacement shall be verified.
f.
Mechanical Snubbers Functional Test Acceptance Criteria
- The mechanical snubber functional test shall verify that:
1.
The force required to initiate or maintain motion of the snubber is within the specified range in both directions of travel.
2.
Activation (restraining action) is achieved within the specified range of velocity or acceleration in both tension and compression.
3.
Snubber release rate,'where required, is within the specified range in compression or tension.
For snubbers specifically required not to displace under continuous load, the ability of the snubber to withstand load without displacement shall be verified.
g.
. Functional Test Failure Analysis An engineering evaluation shall be made of each failure to meet the i
functional test acceptance criteria to determine the cause of the-failure.
The results of this evaluation shall be used, if applicable, in selecting snubbers to be tested in an effort to determine the OPERABILITY of other snubbers irrespective of type which may be subject to the same failure' mode.
For the snubbers found inoperable, an engineering evaluation shall be performed on the components to which the inoperable snubber are attached. The purpose of this engineering evaluation shall be to determine if the components to which the inoperable snubbers were attached were adversely affected by the inoperability of the snubbers in order to ensure that the component remains capable of meeting the 4
designed service.
- Testing methods may be used to measure parameters indirectly or parameters other than those specified if those results can be correlated to the specified parameters through established methods.

SURVEILLANCE REQUIREMENTS (Continued)
If any snubber selected for functional testing either fails to lockup,or fails to move, i.e., frozen in place, the cause will be evaluated and if caused by manufacturer or design deficiency all snubbers of the same type subject to the same defect shall be functionally tested.
This testing requirement shall be independent of the~ requirements stated in' Specification 4.7.6.e. or 4.7.6.f. for snubbers not-meeting the functional test acceptance criteria.
h.
Functional Testing of Repaired and Replaced Snubbers Snubbers which fail the visual inspection or the functional test acceptance criteria shall be repaired or replaced.. Replacement snubbers and snubbers which have repairs.which might affect the functional test result shall be tested to meet the functional test-criteria before installation in the unit.
These snubbers shall have met the acceptace criteria subsequent to their most.recent service, and the functional test must have been performed within 12 month before being installed in the unit.
i.
Snubber Service Life Monitorina A record of the service life of each snubber, the date at which the designated service life commences and the instal-lation and maintenance records on which the designated service. life is based shall be maintained as required by i
Specification 6.10.2.1.
Concurrent with the first inservice visual inspection and at least once per 18 months thereafter, the installation and maintenance records for each snubber shall be. reviewed to verify that the indicated service life has not been exceeded or will not be exceeded prior to the next scheduled snubber service life review.
If the indicated service life will be exceeded prior to the next scheduled snubber service life review, the snubber service life shall be reevaluated or the snubber shall be replaced or reconditioned so as to extend its service life beyond the date of the next scheduled service life review.
This reevaluation, replacement or reconditioning shall be indicated in the records.
I j.
Transient Event Inspections An inspection shall be performed of all hydraulic and mechanical snubbers attached to sections of safety systems that have y*
experienced unexpected, potentially damaging transients as determined from a review of operational data and a visual inspection of the systems within 6 months following a determination thet such an event has occurred.
In addition to satisfying the visual inspection acceptance criteria, freedom of motion of mechanical snubbers shall be verified using one of the following:
(1) manually induced snubber movement; (ii) evaluation of in place snubber piston l_
setting; (iii) stroking the mechanical snubber through its full y
range of travel.
