Visual Inspection Acceptance Criteria Visual inspections shall verify that:
(1) there are no visible indications of damage or impaired OPERABILITY, (2) attachments to the foundation or support structure are secure, and (3) fasteners for attachment of the snubber to the component and to 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 irrespective of type on that system that may be generically susceptible; and (2) the affected snubber is functionally tested in the as-found condition and determined OPERABLE per Specifications 4.7.5.f.
All snubbers connected to an inoperable common hydraulic fluid reservoir shall be counted as inoperable snubbers.
For those snubbers common to more than one system, the OPERABILITY of such snubbers shall be considered in assessing the surveillance schedule for each of the related systems.
d.
Transient Event Inspection An inspection shall be performed of all hydraulic and mechanical snubbers attached to sections of systems that have experienced unexpected, potentially damaging transients as determined from a review i
l of operational data and a visual inspection of the systems within 6 l
months following such an event. In addition to satisfying the visual i
inspection criteria, freedom-of-motion of mechanical snubbers shall be verified using at least one of the following:
(1) manually induced snubber movement; or (2) evaluation of in place snubber piston setting; J
or (3) stroking the mechanical snubber through its full range of l
travel.
The inspection interval for each type of snubber on a given system shall l
a not be lengthened more than one step at a time unless a generic problem j
has been identified and corrected; in that event the inspection interval may be lengthened one step the first time and two steps thereafter if no inoperable snubbers of that type are found on that system.
b The provisions of Specification 4.0.2 are not applicable.
l c For Snubbers located on the reactor recirculation system, a one-time only exemption is allowed to extend this inspection interval to 18 months + 25%,
l for the inspection interval commencing November 11, 1988.
