PLANT SYSTEMS 3/4.7.9 HYDRAULIC SNUBBERS LIMITING CONDITION FOR OPERATION 3.7.9.1 All hydraulle snubbers listed in Table 3.7-3 shall be OPERABLE.
l APPLICABILITY:
MODES 1,2,3 and 4.
ACTION:
With one or more hydraulic snubbers inoperable, replace or restore the inoperable snubber (s) to OPERABLE status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or be in at least HOT STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in COLD SHUTDOWN within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.
SURVEILLANCE REOUIREMENTS 4.7.9.1 Hydraulic snubbers will be demonstrated OPERABLE by performance of the following ajgmented inservice inspection program and the requirements of Specification 4.0.5.
l a.
Each hydraulle snubber with seal material fabricated from ethylene l
propylene or other materials demonstrated compatible with the operating environment and approved as such by the NRC, shall be determined l
OPERABLE at least once after not less than 4 months but within 6 months l
of initial criticality and in accordance with the inspection echedule of Table 4.7-4 thereafter, by a visual inspection of the snubber. Visual inspections of the snubber shall include, but are not necessarily limited to, inspection of the hydraulic fluid reservoirs, fluid connections, and linkage connections to the piping and anchors. Initiation of the Table 4.7-4 inspection schedule shall be made assuming the unit was previously at the 6 month inspection interval.
b.
Each hydraulle snubber with seat material not fabricated from ethylene propylene or other materials demonstrated compatible with the operating-environment shall be determined OPERABLE at least once per 31 days by a I
visual inspection of the snubber. Visual inspection of the snubbers shall l
include but are not necessarily limited to, inspection of the hydraulic fluid reservoirs, fluid connections, and linkage connections to the piping and anchors.

l I-Snubbers may 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 f
The required inspection interval shall not be lengthened more than one step at a time. Following the 1983 refuelin.- 7tage, the first I
inservice visual inspection of accessible snubbers shall be performed after 4 months but within 10 months of co.- ~aencing POWER f
l OPERATION. Subsequent intervals shall be determined by the above Table.
I For the duration of Cycle Five, as many inaccessible snubbers as possible shall be visually inspected during any mid-cycle outage (s).
+
These inspections should not increase the duration of the outage (s).
