NILLSTONE - UNIT 3 3/4 8-1 Amendment No. JJ 97 0186
A. C. 500RG11 SHUTDOWN LINITING CONDITION FOR OPERATION 3.8.1.2 As a minimum, the following A. C. electrical power sources shall be OPERABLE:
a.
One circuit between the offsite transmission network and the I
Onsite Class 1E Distribution System, and b.
One diesel generator with:
1)
A day tank containing a minimum volume of 278 gallons of
- fuel, 2)
A fuel storage system containing a minimum volume of 32,760 gallons of fuel, 3)
A fuel transfer pump, 4)
Lubricating oil storage containing a minimum total volume of 280 gallons of lubricating oil, and 5)
Capability to transfer lubricating oil from storage to the diesel generator unit.
APPLICABILITY:
MODES 5 and 6.
ACTION:
With less than the above minimum required A. C. electrical power sources OPERABLE, immediately suspend all operations involving CORE ALTERATIONS, positive reactivity changes, movement of irradiated fuel, or crane operation with loads over the fuel storage pool, and within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />, depressurize and vent the Reactor Coolant System through a greater than or equal to 5.4 square inch vent.
In addition, when in MODE 5 with the reactor coolant loops not filled, or in MODE 6 with the water level less than 23 feet above the reactor vessel flange, immediately initiate corrective action to restore the required sources to OPERABLE status as soon as possible.
SURVEILLANCE REQUIRENENT 4.8.1.2 The above required A.C. electrical power sources shall be demonstrat-ed OPERABLE by the performance of each of the requirements of Specifications 4.8.1.1.1, 4.8.1.1.2 (except for Specification 4.8.1.1.2a.6), and 4.8.1.1.3.

3/4.8 ELECTRICAL POWER SYSTEMS BASES 3/4.8.1. 3/4.8.2 and 3/4.8.3 A.C. SOURCES. D.C. SOURCES. and ONSITE POWER DISTRIBUTION Technical Specifications 3.8.1.1.b.1 and 3.8.1.2.b.1 require a minimum volume of 278 gallons be contained in each of the diesel generator day tanks. This capacity ensures that a minimum usable volume of 189 gallons is available to permit operation of each of the diesel generators for approximately 27 minutes with the diesel generators loaded to the 2,000 hour0 days <br />0 hours <br />0 weeks <br />0 months <br /> rating of 5335 kW. The shutoff level for the (two) fuel oil transfer pumps is 493 gallons (413 gallons usable volume) which corresponds to approximately 60 minutes of engine operation at the 2,000 hour0 days <br />0 hours <br />0 weeks <br />0 months <br /> rating. The first pump has a make-up setpoint of 372 gallons (284 gallons usable volume) which corresponds to approximately 42 minutes of operation at the 2,000 hour0 days <br />0 hours <br />0 weeks <br />0 months <br /> rating. The 278 gallon day tank low level value corresponds to the auto make-up setpoint of the second pump and is therefore the lowest value of fuel oil with auto make-up capability.
Loss of the two redundant pumps would cause day tank level to drop below the minimum value.
Technical Specifications 3.8.1.1.b.2 and 3.8.1.2.b.2 require a minimum volume of 32,760 gallons be contained in each of the diesel generator's fuel storage systems. This capacity ensures that a minimum usable volume (29,180 gallons) is available to permit operation of each of the diesel generators for approximately three days with the diesel generators loaded to the 2,000 hour0 days <br />0 hours <br />0 weeks <br />0 months <br /> rating of 5335 kW.
The ability to cross-tie the diesel generator fuel oil supply tanks ensures that one diesel generator may operate up to approximately t
six days. Additional fuel oil can be supplied to the site within twenty-four hours after contacting a fuel oil supplier.
