Visual Inspection Acceptance Criteria Visual inspections shall verify (1) that there are no visible indica-tions of damage or impaired OPERABILITY, (2) attachments to the founda-tion or supporting structure are functional, and (3) fasteners for attachment of the snubber to the component and to the snubber anchor-age are functional.
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 that may be generically susceptible; and (2) the affected snubber is functionally tested in the as-found condition and determined OPERABLE per Specification 4.7.7.lf.
All snubbers connected to an inoperable common hydraulic fluid reservoir shall be counted as inoperable snubbers, d.
Transient Event Inspection A visual inspection shall be performed of all hydraulic end mechanical snubbers attached to sections of systems that have experienced unexpected, potentially damaging transients as determined from a review of operational data.
This inspection shall be performed within 6 months following such an event.
In addition to satisfying the visual inspection acceptance 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; or (3) stroking the mechanical snubber through its full range of travel.
- The inspection interval for each type of snubber shall not be lengthened more than one step at a time unless a generic problem has been identified and cor-rected; in that event the inspection interval may be lengthened one step the first time and two steps thereafter if no inoperable Srubbers of that type are found.
- The provisions of Specification 4.0.2 are not applicable.
- For Unit 1, Cycle 4, the Inspection Period is 15 months 125%.

PLANT SYSTEMS SURVEILLANCE REQUIREMENTS (Continued) e.
Functional Tests During the first refueling shutdown and at least once per 18 months thereafter during shutdown, a representative sample of snubbers of each type shall be tested using one of the following sample plans.
The sample plan shall be r, elected prior to the test period and cannot be changed during the test period. The NRC Regional Admini-strator shall be notified in writing of the sample plan selected for
'i each snubber type prior to the test period or the sample plan used in the prior test period shall be implemented:
1)
At least 10% of the total of each type of snubber 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 4.7.7.1f., 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; or 2)
A representative sample of each type of snubber shall be func-tionally tested in accordance with Figure 4.7-1.
"C" is the total number of snubbers of a type found not meeting the accep-tance requirements of Specification 4.7.7.lf.
The cumulative number of snubbers of a type tested is denoted by "N".
At the end of each day's testing, the new values of "N" and "C" (pre-vious day's total plus current day's increments) shall.be plotted on Figure 4.7-1.
If at any time the point plotted falls in the " Reject" region, all snubbers of that type shall be functional 1g tested.
If at any t'lme the point plotted falls in the " Accept region, testing of snubbers of that type may be terminated. When the point plotted lies in the " Continue Testing" region, sdditional snubbers of that type shall be tested until the
" Reject" region, point falls in the " Accept" region or the or all the snubbers of that type have been tested; or 3)
An initial representative sample of 55 snubbers shall be func-tionally tested. For each snubber t functional test acceptance criteria,ype which does not meet the another sample of at least one-half the size of the initial sample shall be tested until the total number tested is equal to the initial sample size multiplied by the factor,1 + C/2, where "C" is the number of snubbers found which do not meet the functional test acceptance criteria.
The results from this sample plan shall be plotted using an " Accept" line which follows the equation N = 55(1 + C/2).
Each snubber point should be plotted as soon as the snubber is tested.
If the point plotted falls on or below the " Accept" line, testing of that type of snubber may be terminated.
If the point plotted falls above the " Accept" line, testing must continue until the point falls in the " Accept" region or all the snubbers of that type have been tested.
