..To previde further assurance of snubber reliability, a representa-tive sample of the installed snubbers will be functionally tested at 18 month intervals.
("Once each refueling shutdown" as indicated in the specification defines the frequency, not the operational mode required for l
performance of functional testing of snubbers.)
Alternatively, snubbers may be tested on-line.
These tests will include stroking of the snubbers to verify proper piston movement, lock-up and bleed. Observed failures of i
these sample snubbers will require functional testing of additional units.
To minimize personnel exposures, snubters installed in areas which have high radiation fields during shutdown or a especially difficult to remove locations may be exempted from these functional testing requirements l
provided the OPERABILITY of these snubbers was demonstrated during functional testing at either the completion of their fabrication or at a subsequent date.
