Revision: i lhe current visual e< amination frequency table is based only on the number of inoperable snubbers found during the previous visual inspection, irrespective of the size of the snubber population.
TRH Change Request Number: 1R 91003.1 SER/SSLR 1mpact: No 3*6 3 See page No(s):3-6 Delete re f erences to t he " Reject Line" wit h respect to the "37" sample plan in section 3.le(2).
Revision:
1his change is being made to climinate the "keject Line" f rom the 37 plan. Deleting the " Reject Line" will eliminate the possibility of rejecting a good snobber population without increasing the possibility of accepting a bad population. ASHL/ANS) OH 1981 Part 4 w'is revised to delete the " Reject Line" from the : tandat d.

Revision:
Because there is a choice of three sample plans, 10%.
37%, and 55%, with the 55% plan being the least desirable to use, the 551 plan is being deleted. The 55% plan would not be uaed at CPSES by choice, in addition, Ast1E/ ANSI OH 1987, Part 4. niso deletes the 55% plan, TRM Change Request Number: 1R 91003.3 SLp!SSER linpact: No 37 3 See Paoe No(s):3-7 Oclete ref er ence to sunhbets specifically reqntred not to displate under tontinuous load in sect ion 3,1f t 4 ) .

f Snubbers may be categorized, based upon their 5 -
accessibility during power operation, as accessible or l inaccessible. These categories may be examined separately or jointly. However, the licensee must make and document that decision before any inspection and shall use that decision as the basis upon which to determine the .
next inspection interval for that category. j Note 2: Interpolation between population or category sizes and the 5 l number of unacceptable snubbers is permissible. Use next {
lower integer for the value of the limit for Columns A, B, !
or C if that integer includes a fractional value of l unacceptable snubbers as determined by interpolation. ;
t Note 3: If the number of unacceptable snubbers is equal to or less 5 l than the nuniber in Column A, the next inspection interval i may be twice the previous interval but not greater than 48 :
months. [
Note 4: If the number of unacceptable snubbers is equal to or less 5 !
than the number in Column B, but greater than the number !
in Column A, the next inspection interval shall be the !
same as the previous interval.
Note 5: If the number of unacceptable snubbers is equal to or 5 greater than the number in Column C, the next inspection interval shall be two-thirds of the previous interval.
However, if the number of unacceptable snubbers is less than the number in Column C but greater than the number in Column B, the next interval shall be reduced proportionally be interpolation, than is, the previous interval shall be reduced by a factor that is one-third of the ratio of the difference between the number of unacceptable snubbers found during the previous ifiterval and the number in Column B to the difference in the numbers in Columns B and C.
Note 6: The provisions of Specification 4.0.2 are applicable for 5 all inspection intervals up to and including 48 months.

An inspection shall be performed of all snubbers attached to !

satisfying the visual inspection acceptance criteria, freedom-of- i motion of mechanical snubbert. shall be verified using at least one l of the following: (1) manually induced snubber mo dment; or (2) evaluation of in-place snubber piston setting; or (3) stroking the i mechanical snubber through its full range of travel.

- e. Functional Tests During the first refueling e.hutdown and at least once per 18 !
months thereafter during shutdown, a representative sanple of :
snubbers of each type shall be tested using one of the following ,
sample plans. The sample plan for each type shall be selected prior to the test period and cannot be changed during the test period. The NRC Regional Administrator shall be notified in ;
writing of the sample plan selected for each snubber type prior to the test period or the sample plan used in the prior test period ,
shall be implemented:
- I
- 1) At least 10% of the total of each type of snubber shall be l 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 Test / Inspection TR3.lf, 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 functionally tested in accordance with figure 3.1-1. "C" is the total number of snubbers of a type found not meeting the acceptance requirements of Test / Inspection TR3.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" (previous day's total plus current day's increments) shall be plotted on Figure 3.1-1. If at any time the point plotted falls in the " Accept" region, testing of snubbers of that type may be terminated. When the point plotted lies in 5 the " Continue Testing" region, additional snubbers of that type shall be tested until the point falls in the " Accept" region, or all the snubbers of that type have been tested.

The snubber functional test shall verify that:
- 1) Activation (restrainir.g action) is achieved within the ,
specified range in both tension and compression; ,
- 2) Snubber bleed, or release rate where required, is present in !
both tension and compression, within the specified range; ;
