This period is acceptable based on the remaining capacity

(> 6 days), the fact that procedures will be initiated to obtain replenishment, and the low probability of an event during this brief period.

With the required ACTION and associated completion time not met, the associated EDG may be incapable of performing its intended function and must be immediately declared inoperable.

With the stored fuel oil viscosity not within the required limits, a period of 30 days is allowed for restoration.

This restoration may involve feed and bleed procedures, filtering, or combinations. of these procedures.

Even if an EDG start and load was required during the 30 day frequency and the fuel oil viscosity was outside its limits, there is a high likelihood that the EDG would still be capable of performing its intended function.

With the required ACTION and associated completion time not met, the associated EDG may be incapable of performing its intended function and must be immediately declared inoperable.

With the stored fuel oil water and sediment not within the required limits, the associated EDG may not be capable of performing its intended function and must be immediately declared inoperable.

SURVEILLANCE REQUIREMENTS:

SR 4.8.1.3.1.1 provides verification that there is an adequate inventory of fuel oil in the storage tanks to support each EDG's operation for 7 days at full load.

The 7 day period is sufficient time to place the unit in a safe shutdown condition and to bring in replenishment fuel from an outside source.

The 31 day SR is adequate to ensure that a sufficient supply of fuel oil is available, since low level.alarms are provided and unit operators would be aware of any large uses of fuel oil during this period.

SR 4.8.'1.3.1.2 ensures the availability of high quality fuel oil for the EDGs.

The frequency of this test (92 days).takes into consideration the low humidity and infrequent rainfall at the site and is an exception to RG 1.137, and is consistent with UFSAR Section 1.8.

SR 4.8.1.3.2 'ensures that the cathodic protection system is capable of minimizing external corrosion for the fuel oil storage tanks.

This period is acceptable based on the remaining. capacity

(> 6 days), the fact that procedures will be initiated to obtain replenishment, and the low probability of an event during this brief period.

With the required ACTION and associated completion time not met, the associated EDG may be incapable of performing its intended function and must be immediately declared inoperable.

With the stored fuel oil viscosity not within the required limits, a period of 30 days is allowed for restoration; This restoration may involve'eed and bleed procedures, filtering, or combinations of these procedures.

Even if an EDG start and load was required during the 30 day frequency and the fuel oil viscosity was outside its limits, there is a high likelihood that the EDG'would still be capable of performing its intended function.

With the required ACTION and associated completion time not met, the associated EDG may be incapable of performing its intended function and must be immediately declared inoperable.

With the stored fuel oil water and sediment not within the required limits, the associated EDG may not be capable of perform'.ng its intended function and must be immediately declared inoperable.

"-"-'~.SURVEILLANCE REQUIREMENTS:

SR 4.8.1.3.1.1 provides verification that there is an adequate inventory of fuel oil in the storage tanks to support each EDG's operation for 7 days at full load.

The 7 day period is sufficient time to place the unit in a safe shutdown condition and to bring in replenishment fuel from an outside source.

The 31 day SR is adequate to ensure that a sufficient supply of fuel oil is available, since low level alarms are provided and unit operators would be aware of any large uses of fuel oil during this period.

SR 4.8.1.3.1.2 ensures the availability of high quality fuel oil for the EDGs.

The frequency of this test (92 days) takes into consideration the low humidity and infrequent rainfall at the site and is an exception to RG I.I37, and is consistent with UFSAR Section 1.8.

SR 4.8.1.3.2 ensures that the cathodic protection system is capable of minimizing external corrosion for the fuel oil storage tanks.

Operation with a battery cell's parameter outside the normal limit but within the allowable value specified in Table 4.8-2 is permitted for up to 7 days.

During this 7-day period:

(1) the allowable values for electrolyte level ensures

.no physical damage to the plates with an adequate electron transfer capability; (2) the allowable value for the average specific gravity of all the cells, not more than 0.020 below the manufacturer's recommended full charge specific gravity, ensures that the decrease-in rating will be less than the safety margin provided in sizing; (3) the allowable value for an individual cell's specific gravity, ensures that an individual cell's specific gravity will not be more than 0.040 below the manufacturer's full charge specific gravity and that the overall capability of the battery will.be maintained within an acceptable limit: and (4) the allowable value for an individual cell's float voltage. greater than 2.07 volts (low specific gravity cells) 2. 14 volts (AT8T), ensures the battery's capability to perform its design function.
