The Point Beach DC electrical system has been modified so that each of the four main DC distribution buses, which are shared between the two units, has its own power supplies consisting of a safety-related station battery (DOS, D06, D105, D106) and a battery charger. In addition to these bus-specific power supplies, a swing safety-related battery (D305) is inetsited which is capable of being conr.ected to any one of the four main C4 distribution buses. Swing battery t chargers are also provided. Under cormal circumstances, one battery and one battery charger are connected in each main DC distribution bus. The battery charger normally shall be in service on each battery so that the batteries will always be at full charge in anticipation of a loss-of-AC power incident. Under unusual circumstances, two of the five safety-related batteries may be out of service for a limited period of time provided one of the two out-of-service batteries is returned to service within the time periods specified in ,

Specification 15.3.7.B.I.hi.. These limiting conditions for operation ensure that adequate DC power will always be available for starting the emergency generators and other emergency uses.  !

The EDG fuel oil system is considered operable when 1) 11,000 gal. of fuel oil is initially available in the emergency fuel oil.fstorage tank Mich[supplie.s to the diesel generators [Because the EDGs consume approximately 205 gallons of fuel per hour when fully loaded, the 11,000 gallon fuel supply in the emergency fuel tank provides sufficient fuel to operate one EDG at design load for more than 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />.], 2) the EDG day tank for;ithat}EDGI ;is;operabis and f6KG;0f[isd[G20 2[thj associated motor-operated fill valve are is operable, 3) for G-Ol[and;Gs02r at least one of the two base-mounted sump tank fuel oil transfer pumps is operable, and 4) the fuel oil transfer pump ' y;s stem associated with the EDG is operable.

However, both the fuel oil transfer pump: and- the4r :::cciatc 3 are system is allowed to be out of service for four hours for.p pipi 9.and G01 and;GIO2 due valve:

The EDG ventilation system is considered operable when diesel room temperature can be maintained $120'F with the diesel engine operating at full load. Temperature will be maintained $120 'F if 1) all gravity-operated louvers are operable, and

2) both diesel room exhaust fans are operable M forlG-Ollihd]GE02i one diesel room exhaust fan is operable and outside air temperature is 580'F.
