4.16 Inservice Inspection Program for Shock Suppressors (Snubbersl Applicability 4.16.l Applies to periodic surveillance of safety-related snubbers as described per Specification 3.20.
Speci fi cations
- a.
Each snubber shall be demonstrated OPERABLE by performance of the following augmented inservice inspection program in addition to the requirements of Specification 4.0.5. As used in this specification, "type of snubber" sha 11 mean snubbers of the same design and manufacturer, irrespective of capacity.
Visual Inspection Snubbers are categorized as inaccessible or accessible during reactor operation.
Each of these categories (inaccessible and accessible) may be inspected independently according to the following paragraph:
If one or more unacceptable snubbers are found, the next inspection interval shall be 2/3 (-25%) of the previous interval.
If no unacceptable snubbers are found, the next interval may be doubled (-
25%),
but not to exceed 48 months.
The interval extension provisions of Technical Specification 4.0.2 are applicable for all inspection intervals up to and including 48 months.
Inspections performed before the interval has elapsed may be used as a new reference point to determine the next inspection.
- However, the results of such early inspections, performed before the original required time i~~erval has el~psed (Dominal time less 25%), may not be used to lengthen the required inspection interval.
Any inspecti.on whose results require a shorter inspection interval will override the previous schedule.
- b.
Visual Inspection Acceptance Criteria Visual inspection shall verify that (1) the snubber has no visible indications of damage or impaired OPERABILITY, (2) attachments to the foundation or supporting structure are functional, and (3) fasteners for the attachment of the snubber to the component and to the snubber anchorage are functional.
Snubbers which appear inoperable as a result of visual inspections shall be classified as unacceptable and may be reclassified acceptable for tbe purpose of establishing the rie~t ~isual inspection interval, provided that (1) the cause of the rejection is clearly established and remedied for 4-71 Amendment No.
~~, ~~, J~l
4.16.1 Specifications (continued) that particular snubber and for other snubbers, irrespective of type, that may be generically susceptible; and (2) the affected snubber is functionally tested in the as-found condition and determined OPERABLE per Technical Specification 4.16.ld or 4.16.le, as applicable. All snubbers found connected to an inoperable common hydraulic fluid reservoir shall be counted as unacceptable for determining the next inspection interval. A review and evaluation sha 11 be performed and documented to justify continued operation with an unacceptable snubber.
If continued operation cannot be justified, the snubber shall be declared inoperable and the action requirements shall be met.

4.16.1 Each snubber shall be demonstrated OPERABLE by performance of the following augmented inservice inspection program in addition to the requirements of Specification 4.0.5.
As used in this specification, "type of snubber" shall mean snubbers of the same design and manufacturer, irrespective of capacity.
- a.
Visual Inspection Snubbers are categorized as inaccessible or accessible during reactor operation.
Each of these categories (inaccessible and accessible) may be inspected independently according to the following paragraph:
If one or more unacceptable snubbers are found, the next inspection interval shall be 2/3 (-25%) of the previous interval. If no unacceptable snubbers are found, the next interval may be doubled (-25%), but not to exceed 48 months.
The interval extension provisions of Technical Specification 4.0.2 are applicable for all inspection intervals up to and including.48 months.
Inspections performed before the interval has elapsed may be used as a new reference point to determine the next inspection.
However, the results of such early inspections, performed before the original required time interval has elapsed (nominal time less 25%), may not be used to lengthen the required inspection interval.
Any inspection whose results require a shorter inspection interval will override the previous schedule.
- b.
Visual Inspection Acceptance Criteria Visual inspection shall verify that (1) the snubber has no visible indications of damage or impaired OPERABILITY, (2) attachments to the foundation or supporting structure are functional, and (3) fasteners for the attachment of the snubber to the component and to the snubber anchorage are functional. Snubbers which appear inoperable as a result of visual inspections shall be classified as unacceptable and may be reclassified acceptable 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, irrespective of type, that may be generically susceptible; and (2) the affected snubber is functionally tested in the as-found condition and determined OPERABLE per Technical Specification 4.16.ld or 4.16.le, as applicable. All snubbers found connected to an inoperable common hydraulic fluid reservoir shall be counted as unacceptable for determining the next inspection interval. A review and evaluation shall be performed and documented to justify continued operation with an unacceptable snubber.
If
Jr continued operation cannot be justified, the snubber shall be declared inoperable and the action requirements sha 11 be met.
