! l l BASES l BACKGROUND Each diesel generator (DG) is provided with a storage tank having a fuel

! oi! capacity sufficient to operate that diesel for a period of 7 days while the DG is supplying maximum post loss of coolant accident load demand discussed in the UFSAR, Section 9.5.4.2 (Ref.1). The maximum load ,

demand is calculated using the assumption that a minimum of any two DGs is available. This onsite fuel oil capacity is sufficient to operate the DGs for longer than the time to replenish the onsite supply from outside sources.

i Fuel oil is transferred from storage tank to day tank by gravity transfer.

All outdde tanks and piping are located underground.

l l For prcper operation of the standby DGs, it is necessary to ensure the proper quality of the fuel oil. Regulatory Guide 1.137 (Ref. 2) addresses the recommended fuel oil practices as supplemented by ANSI N195 (Ref. 3). The fuel oil properties governed by these SRs are the water and sediment content, the kinematic viscosity, specific gravity (or API gravity),

and impurity level.

The DG lubrication system is designed to provide sufficient lubrication to  ;

permit proper operation of its associated DG under all loading conditions.

l The system is required to circulate the lube oil to the diesel engine working surfaces and to remove excess heat generated by friction during ,

operation. Each engine oil sump contains an inventory capable of 1 supporting a minimum of 7 daysof operation.fThe onfite storag in  ;

j Caddfion to thfengine oil syfnp is sufficight to ensure /7 days of coAtinuous QDeration.fThis supply is sufficient to all6w the operator to  !

replenish lube oil from outside sources. I l

Each DG has an air start system with adequate capacity for five successive start attempts on the DG without recharging the air start receiver (s).

Description of Proposed Changes 5

ITS 3.8.3 delineates requirements for the Diesel Generator l Fuel Oil, Lube Oil, and Starting Air Systems. Specifically,  ;

ITS 3.8.3 requires a diesel lube oil inventory of g 600 (

j gallons. Condition B states that with one or more diesels t l_ with lube oil inventory < 600 gallons and > 575 gallons, the  ;

l lube oil inventory must be restored to within limits within  ;

i 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />. SR 3.8.3.2 requires verification that the lube  ;

oil inventory is 3 600 gallons on a 31 day frequency. ,

This amendment request changes the 600 gallon requirement to i 400 gallons. In addition, the 575 gallon lower limit of

{

i Condition B is modified to.375 gallons. Refer to the ITS '

3.8.3 markups for the changes. '

I

! Corresponding changes to the-Bases for ITS 3.8.3 are also i l made as indicated in the proposed markups. Note that in the i l Bases Background section, the fourth paragraph is modified [

L to delete the next to the last sentence. This statement is I misleading, in that the engine oil sump inventory alone is i sufficient to ensure 7 days of continuous operation, without l' relying on the onsite storage capability. This sentence was bracketed in NUREG-1431, " Standard Technical Specifications, L Westinghouse Plants," and should not have been included in the Catawba Bases. Also, in the Bases for ITS SR 3.8.3.2, the-discussion pertaining to the transfer of lube oil from l its storage location to the diesel is deleted, since the i t

sump inventory alone is sufficient to meet the 7 day  ;

requirement. In the second paragraph of the ITS SR 3.8.3.2 )

Bases discussion, the word "onsite" is changed to i "available" to be consistent with the above change.  :

L Clarification is also added to the ITS SR 3.8.3.2 Bares )

discussion to indicate that the 400 gallon requirement must J be met whether or.not the diesel generator is running. I Finally, a typographical error (Condition "D" should be Condition "E") is being corrected in the first line of the Bases Actions section at the top of page B 3.8.3-5. NUREG-1431 contained this error and it was translated into the Catawba ITS Bases.

l These revised requirements are consistent with the design of i the Diesel Generator Lube Oil System at Catawba. 1 Technical Justification The Diesel Generator Lube Oil System provides sufficient i

, lubrication to permit proper operation of the diesel  ;

! generators under all loading conditions. The system

circulates the lube oil to the diesel engine working

! l I

l

surfaces and removes excess heat generated by friction during engine operation. Each engine oil sump contains an inventory capable of supporting a minimum of 7 days of operation. This supply is sufficient to allow the operator to replenish lube oil from outside sources.

Catawba calculation CNC-1223.59-02-0003, " Diesel Generator Lube Oil System Verification Calculation," Revision 4, dated November 2, 1998, determined the lube oil requirements for the diesels. This calculation indicates that an anti-vortexing baffle is present at the bottom of eac'n lube oil sump tank, resulting in an unusable volume of 161.4 gallons.

The calculation requires a 7 day supply of oil above the tank baffle. According to vendor calculations, the burn rate for diesel lube oil is 1.2 gallons per hour. A 7 day supply of lube oil therefore requires 1.2 gallons per hour x 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> / day x 7 days = 201.6 gallons. This 201.6 gallon requirement must be added to the unusable volume in the sump, resulting in a sump inventory requirement of 161.4 gallons + 201.6 gallons = 363 gallons. Therefore, 363 gallons are required in the tank to ensure a 7 day requirement. For conservatism, an ITS volume requirement of 400 gallons is being selected. The lower limit of ITS 3.8.3 Condition B is chosen to be 375 gallons. The Bases states that the lower limit of Condition B needs to ensure at least a 6 day supply. A 375 gallon lower limit for Condition B will therefore easily meet the 6 day requirement of Condition B. The normal level in the sump tank is approximately 540 gallons when the diesel generator is in standby condition (not running). When the diesel is started and lube oil is circulated through the engine, the sump tank inventory drops to approximately 450 gallons. Therefore, the 400 gallon ITS limit can easily be met whether or not the engine is running. Catawba plans to raise the existing low lube oil alarm setpoint from its present value of 385 gallons to 415 gallons. This alarm will therefore annunciate prior to the 400 gallon ITS value being reached.

Refer to the attached Figure 1 for a graphical representation of diesel generator lube oil inventory requirements.

The proposed ch..nges are therefore determined to be acceptable, since a 400 gallon ITS requirement will support operation of the diesel generator at full load for a 7 day period.

Note that the previous ITS values of 600 gallons and 575 gallons were based on incorrect information in the Catawba UFSAR. Section 9.5.7.2.1 of the UFSAR indicates that the lube oil sump tank has a 700 gallon capacity. It also

I indicates that the normal operating volume of the sump tank i

No Significant Hazards Consideration Determination l l

l The following discussion is a summary of the evaluation of i l the changes contained in this proposed amendment against the j i 10 CFR 50.92(c) requirements to demonstrate that all three  :

l standards are satisfied. A no significant hazards  !

l consideration is indicated if operation of the facility in j l accordance with the proposed amendment would not:

i l 1. Involve a significant increase in the probability or consequences of an accident previously evaluated, or i I

2. Create the possibility of a new or different kind of j l accident from any accident previously evaluated, or t
3. Involve a significant reduction in a margin.of safety.  ;

First Standard Implementation of this amendment would not involve a significant increase in the probability or consequences of an accident previously evaluated. Approval of this amendment will have no significant effect on accident I probabilities or consequences. The Diesel Generator Lube L Oil System is not an accident initiating system; therefore, l there will be no impact on any accident probabilities by the approval of this amendment. The design of the system is not being modified by this proposed amendment. The amendment merely aligns ITS requirements with the existing design and l function of the system. Therefore, there will be no impact on any accident consequences.

Second Standard Implementation of this amendment would not create the possibility of a new or different kind of accident from any accident previously evaluated. No new accident causal l mechanisms are created as a result of NRC approval of this l amendment request. No changes are being made to the plant which will introduce any new accident causal mechanisms.

This amendment request does not impact any plant systems i that are accident initiators, since the Diesel Gene ator i Lube Oil System is an accident mitigating system.  !

Third Standard

, Implementation of this amendment would not involve a significant reduction in a margin of safety. Margin of

, safety is related to the confidence in the ability of the t

fission product barriers to perform their design functions I

i 9

during and following an accident situation. These barriers include the fuel cladding, the reactor coolant system, and the containment system. The performance of these fission product barriers will not be impacted by implementation of this proposed amendment. The Diesel Generator Lube Oil System is already capable of performing as designed. No safety margins will be impacted.

Based upon the preceding analysis, Duke Energy has concluded that the proposed amendment does not involve a significant hazards consideration.

o Environmental Analysis Pursuant to 10 CFR 51.22(b), an evaluation of this license amendment request has been performed to determine whether or not it meetc the criteria for categorical exclusion set  !

forth in 10 CFR 51.22 (c) (9) of the regulations.

l This amendment to the Catawba ITS modifies requirements for the Diesel Generator Lube Oil System to align these requirements with the design and function of the system.

Implementation of this amendment will have no adverse impact upon the Catawba units; neither Will it contribute to any additional quantity or type of effluent being available for adverse environmental impact or personnel exposure.

It has been determined there is:  ;

i

1. No significant hazards consideration,
2. No significant change in the types, or significant increase in the amounts, of any effluents that may be released offsite, and
3. No significant increase in individual or cumulative occupational radiation exposures involved.

Therefore, this amendment to the Catawba ITS meets the criteria of 10 CFR 51.22 (c) (9) for categorical exclusion from an environmental impact statement.
