Snubbers tray be categorized into two groups, " accessible" and " inaccessible".

This categorization shall be based upon the snubber's accessibility for inspection during reactor operation. These two groups may be inspected independently according to the above schedule.

C*

The required inspection interval shall not ce lengthened more than one step at a time.

CCD Snubbers served by the ca.no reservoir are enclosed within a bracket. All reservoirs serving more than one snubber shall be *nspected for proper hydrnulic fluid level: a) within 7 days after startup following a major outage or following maintenance in the in wdiate vicinity of the reservoir or associated piping, and b) every 31 days + 25%.
