PLANT SYSTEMS BASES The inspection frequency applicable to snubbers containing seals fabricated from materials which have been demonstrated compatible with their operating environment (only ethylene proplyene compounds to date) is based upon maintaining a constant level of snubber protection. Therefore, the required inspection interval varies inversely with the observed snubber failures. The number of inoperable snubbers found during'an inspection of these snubbers determines the time interval for the next required inspection of these snubbers. Inspections performed before that interval has elapsed may be used as a new reference point to determine the next inspection. However, the results of such early inspections performed before the original required time interval has elapsed (nominal time less 25$ ) may not be used to lengthen the required inspection interval. Any inspection whose results require a shorter inspection interval will override the previous schedule.

To provide further assurance of snubber reliability, a representative sample of the installed snubbers will be functionally tested during plant shutdowns at 18 month intervals. These tests will include stroking of the snubbers to verify proper piston movement, lock-up and bleed. Observed failures of these sample snubbers will require functional testing of additional units. To minimize personnel exposures, snubbers installed in high radiation zones or in especi ally difficult to remove locations (as identified in Table 3.7-2) may be exempted from these functional testing requirements provided the OPERABILITY of these snubbers was demonstrated during functional testing at either the completion of their fabrication or at a subsequent date.

3/4. 7.11 FIRE SUPPRESSION SYSTEMS The operability of the fire suppression systems ensures that adequate fires suppression capability is available to confine and extinguish fires occurring in any portion of the facility where safety related equipment is located. The fire suppresion system consists of the water system, fire hose stations, yard fire hydrants, hydrant hose houses, and spray and/or sprinkler systems. The collective capability of the fire suppression systems is adequate to minimize potential damage to safety related equipment and is a major element in the facility fire protection program.

In the event that portions of the fire suppr ession systems are inoperable, alternate backup fire fighting equipment is requi red to be made available in the affected areas until the inoperable equipment is restored to service.
