ELECTRICAL POWER SYSTEMS SHUTDOWN LIMITING 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 onsite Class 1E distribution system, and
- b. One diesel generator with:
- 1. A day fuel tank containing a minimum of 70 gallons of fuel,
- 2. A fuel storage system containing a minimum indicated volume of 46,000 gallons of fuel, and
- 3. A fuel transfer pump.
APPLICABILITY: MODES 5 and 6.
ACTION:
With less than the above minimum required A.C. electrical power'ources OPERABLE, suspend all operations involving CORE ALTERATIONS positive reactivity changes* until the minimum required A.C. electrical power sources are restored to OPERABLE status.
SURVEILLANCE RE UIREMENTS 4.8.1.2 The above required A.C. electrical power sources shall be demonstrated OPERABLE by the performance of each of the Surveillance Requirements of 4 '.1.1.1 and 4.8.1.1.2 except for requirement 4.8.1.1.2.a.5.
- For purposes of this specification, addition of water from the RWST does not constitute a positive reactivity addition provided the boron concentration in the RWST is greater than the minimum required by Specification 3.1.2.7.b.2.
COOK NUCLEAR PLANT - UNIT 1 3/4 8-9 AMENDMENT NO.
s ELECTRICAL POWER SYSTEMS Continued BASES Removal of accumulated water as required by 4.8.1.1.2.b,2 is performed by drawing the contents off the bottom of the tank until acceptable results are obtained for either a tape test or a water and sediment test. An acceptable result for the water and sediment content is a'easured value less than 0.05 percent volume.
The sample specified in 4.8.1.1.2.c.4 is sent offsite for testing. A serious attempt will be made to meet the 31-day limit on the offsite tests; however, if for some reason this limit is not met (e.g., if the sample is lost or broken or if the results are not received in 31 days), the diesel generators should not be considered inoperable. If the smaple is lost, broken, or fails the offsite tests and the new oil has already been put into the storage tank, the offsite tests will be performed on a sample taken from the storage tank.
If the results on the subsequent storage tank sample are not within specified limits, the diesel generators should be considered OPERABLE and the out-of-spec properties should be returned to within specification as soon as possible.
If the monthly storage tank sample taken in accordance with Specification 4.8.1.1.2.d fails the particulate contamination test, the diesel generators should be considered OPERABLE and the contamination level should be restored to below 10 mg/liter as soon as possible.
The precision leak-detection test described in Surveillance Requirement 4.8.1,1.2.f.2 should be performed as described in NFPA (National Fire Protection Association) - 329. As NFPA-329 is revised, the precision leak-detection test may be modified to incorporate changes to the test as described in the revisions to NFPA-329.
The minimum required diesel fuel oil volume is 43,240 gallons. This volume is consistent with operation of one diesel generator continuously for 7 days at rated load, as recommended in Regulatory Guide 1.137, entitled "Fuel Oil System for Standby Diesel Generators." The Technical Specifications require a minimum of 46,000 gallons of fuel. The 46,000 gallons is an indicated volume, This amount includes margin for characteristics such as location of the tank discharge pipes and slope of the tanks.

ELECTRICAL POWER SYSTEMS SHUTDOWN LIMITING CONDITION FOR OPERATION 3.8.1.2 As a minimum, the following A.C. electrical power sources shall be OPERABLE:
One circuit between the offsite transmission network and the onsite Class 1E distribution system, and
- b. One diesel generator with:
- 1. A day fuel tank containing a minimum of 70 gallons of fuel,
- 2. A fuel storage system containing a minimum indicated volume of 46,000 gallons of fuel, and
- 3. A fuel transfer pump.
APPLICABILITY: MODES 5 and 6.
ACTION:
With less than the above minimum required A,C, electrical power sources OPERABLE, suspend all operations involving CORE ALTERATIONS or positive reactivity changes* until the minimum required A.C. electrical power sources are restored to OPERABLE status.
SURVEILLANCE RE UIREMENTS 4.8.1,2 The above required A.C. electrical power sources shall be demonstrated OPERABLE by the performance of each of the Surveillance Requirements of 4.8.1.1.1 and 4.8.1.1.2 except for requirement 4.8.1.1.2,a,5.
- For purposes of this specification, addition of water from the RWST does not constitute a positive reactivity addition provided the boron concentration in the RWST is greater than the minimum required by Specification 3.1.2.7.b.2.

ELECTRICAL POWER SYSTEMS Continued BASES Removal of accumulated water as required by 4.8.1,1.2.b.2 is performed by drawing the contents off the bottom of the tank until acceptable results are obtained for either a tape test or a water and sediment test. An acceptable result for the water and sediment content is a measured value less than 0.05 percent volume.
The sample specified in 4.8.1.1.2.c.4 is sent offsite for testing. A serious attempt will be made to meet the 31-day limit on the offsite tests; however, if for some reason this limit is not met (e.g., if the sample is lost or broken or if the results are not received in 31 days), the diesel generators should not be considered inoperable. If the smaple is lost, broken, or fails the offsite tests and the new oil has already been put into the storage tank, the offsite tests will be performed on a sample taken from the storage tank.
If the results on the subsequent storage'ank sample are not within specified limits, the diesel generators should be considered OPERABLE and the out-of-spec properties should be returned to within specification as soon as possible.
If the monthly storage tank sample taken in accordance with Specification 4.8.1.1.2.d fails the particulate contamination test, the diesel generators should be considered OPERABLE and the contamination level should be restored to below 10 mg/liter as soon as possible.
The precision leak-detection test described in Surveillance Requirement 4.8.1,1.2.f.2 should be performed as described in NFPA (National Fire Protection Association) - 329. As NFPA-329 is revised, the precision leak-detection test may be modified to incorporate changes to the test as described in the revisions to NFPA-329.
The minimum required diesel fuel oil volume is 43,240 gallons. This volume is consistent with operation of one diesel generator continuously for 7 days at rated load, as recommended in Regulatory Guide 1.137, entitled "Fuel Oil System for Standby Diesel Generators." The Technical Specifications require a minimum of 46,000 gallons of fuel. The 46,000 gallons is an indicated volume. This amount includes margin for characteristics such as location of the tank discharge pipes and slope of the tanks.
