8 3.8 ELECTRICAL POWER SYSTEMS B 3.8.3' Diesel Fuel Oil, tube Oil, and Starting Air ,

BASES BACKGROUND Each diesel generator (DG) is provided with a storage tank having a fuel oil capacity sufficient to operate that diesel i for a period of 7 days while the DG is supplying maximum l post loss'of coolant accident load demand discussed in the J FSAR, Sectiot) [9.5.4.2] (Ref.1) . The maximum load demand is calcia sted 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.

Fuel oil is transferred from storage tank to day tank by either of two transfer pumps associated with each storage tank. Redundancy of pumps and piping precludes the failure of one pump, or the rupture of any pipe, valve or tank to result in the loss of more than one OG. All outside tanks, pumps, and piping are located underground. ,. ,

For proper operation of the standby OGs, it is necessary to .

ensure the proper Regulatory Guide '1.137 (Ref. quality of the fuel oil.2)' addresses the recosam practices as supplemented by ANSI M195 (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 06 under all loading conditions. 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 supporting a minimum of [7] days of operation.

[The onsite storage in addition to the engine nil sum '

sufficient to ensure 7 days of continuous operation.]p This is supply is sufficient to allow the operator to replenish lube oil from outride sources.

Each 06 has an air start system with adequate capacity for five successive start attem the air start receiver (s). pts on the DG without recharging (continued)

APPLICABLE SAFETY ANALYSES The initial conditions of Design Basis Accident (D8A) and transient analyses in the FSAR, Chapter [6] (Ref. 4), and in the FSAR, Chapter [15] (Ref. 5), assu:ne Engineered Safety Feature (ESF) systems are OPERABLE.

The DGs are designed to provide sufficient capacity, capability, redundancy, and reliability to ensure the availability of necessary power to ESF systems so that fuel, Reactor Coolant System and containment design limits are not exceeded. These limits are discussed in more detail in the Bases for Section 3.2, i Power Distribution Limits; Section 3.4, Reactor Coolant i

System (RCS); and Section 3.6, Containment Systems.

Since diesel fuel oil, lube oil, and the air start subsystem support the operation of the standby AC power sources, they satisfy Criterion 3 of the NRC Policy Statement.

LCD Stored diesel fuel oil is required to have sufficient supply for 7 days of full load operation. It is also required to meet specific standards for quality. Additionally, sufficient lubricating oil supply must be available to .*

ensure the capability to operate at full load for 7 days.

This requirement, in conjunction with an ability to obtain replacement supplies within 7 days, supports the availability of DGs required to shut down the reactor and to maintain it in a s.fe condition for an anticipated operational occurrence (A00) or a postulated DBA with loss of offsite power. DG day tank fuel requirements, as well as transfer capability from the storage tank to the da are addressed in LCO 3.8.1, 'AC Sources-Operating,y tank,

" and LC0 3.8.2, 'AC Sources-Shutdown."

The starting air system is required to have a minimum capacity for five successive DG start attempts without recharging the air start receivers.

APPLICABILITY The AC sources (LCO 3.8.1 and LCO 3.8.2) are required to ensure the availability of the required power to shut down the reactor and maintain it in a safe shutdown condition after an A00 or a postulated D8A. Since stored diesel fuel oil, lube oil, and the starting air subsystem support LCO 3.8.1 and LCO 3.8.2, stored diesel fuel oil, lebe oil,

ACTIONS M In this Condition, the 7 day fuel oil supply for a DG is not available. However, the Condition is restricted to fuel oil level reductions that maintain at least a 6 day supply. i These circumstances may be caused by events, such as full load operation required after an inadvertent start while at minimum required level, or feed and bleed operations, which may be necessitated by increasing particulate levels or any number of other oil quality degradations. This restriction allows sufficient time for obtaining the requisite 1 replacement volume and performing the analyses required prior to addition of fuel oil to the tank. A period of 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months is considered sufficient to couplete restoration of the required level prior to declaring the DG inoperable.

Thisacceptance the Condition is entered criterion of as SRa3,8.3.5, result of a failure to meet Nonnally, trending of particulate levels allows sufficient time to correct high particulate levels prior to reaching the limit of acceptability. Poor sample procedures (bottom sampling),

contaminated sampling equipment, and errors in laboratory analysis can produce failures that do not follow a trend.

Since the presence of particulates does not mean failure of the fuel oil to burn properly in the diesel engine, and particulate concentration is unlikely to change significantly between Surveillance Frequency intervals, and proper engine perfonsance has been recently demonstrated (within 31 days), it is prudent to allow a brief prior to declaring the associated DG inoperable. period The 7 day Completion Time allows for further evaluation, resampling and re-analysis of the DG fuel oil.

i D.d With the new fuel oil properties defined in the Bases for SR 3.8.3.4 not within the required limits, a period of 30 days is allowed for restoring the stored fuel oil properties. This period provides sufficient time to test the stored fuel oil to determine that the new fuel oil, when i mixed with previously stored fuel oil, remains acceptable, )

or to restore the stored fuel oil properties. This restoration may involve feed and bleed procedures, filtering, or combinations of these procedures. Even if a DG start and load was required during this time interval and the fuel oil properties were outside limits, there is a high likelihood that the DG would still be capable of performing its intended function.

Ed With starting air receiver pressure < [225] psig, sufficient capacity for five successive DG start attempts does not exist. However, as long as the receiver pressure is

> (125] psig, there is adequate capacity for at least one start attempt, and the DG can be considered OPERA 8LE while the air receiver pressure is restored to the required limit.

SURVEILLMCE SR 3.8.3.1 REQUIREMENTS This SR provides verification that there is an adequate inventory of fuel oil in the storage tanks to support each DG'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 offsite location.

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

SR 3.8.3.2 l This Surveillance ensures that sufficient lube oil inventory is available to support at least 7 days of full load operation for each DG., The (500] gal requirement is based on the DG manufacturer consumption values for the run time of the DG.

REQUIREMENTS the level reaching the manufacturer recommended minimum level.

A 31 day Frequency is adequate to ensure that a sufficient ,

lube oil supply is onsite, since DG starts and run time are closely monitored by the unit staff.

SR 3.8.3.3 The tests listed below are a means of determining whether new fuel oil is of the appropriate grade and has not been contaminated with substances that would have an imediate, detrimental impact on diesel engine combustion. If results from these tests are within acceptable limits, the fuel oil may be added to the storage tanks without concern for contaminating the entire volume of fuel oil in the storage tanks. These tests are to be conducted prior to adding the new fuel to the storage tank (s), but in no case is the time between receipt of new fuel and conducting the tests to '

exceed 31 days. The tests, limits, and applicable ASTM Standards are as follows:

a. Sample the new fuel oil in accordance with ASTM D4054-[ ] (Ref. 6);

b. Veri fv in accordance with the tests specified in ASTM !

0975- : ) (Ref. 6) that the sample has an absolute 1 specific gravity at 60/60'F of = 0.83* and s 0.89* or l an API gravity at 60'F of a 27' and s 39', a kinematic l viscosity at 40'C of a 1.9 centistokes and s 4.1 centistokes, and a flash point of a 125*F; and l

c. Verify that the new fuel oil has a clear and bright appearance with proper color when tested in accordance with ASTM D4176-[ ] (Ref 6).

Failure to meet any of the above limits is cause for rejecting the new fuel oil, but does not represent a failure to meet the LCO concern since the fuel oil is not added to the storage tanks.

is acceptable because the fuel oil properties of interest, even if they were not within stated limits, would not have an imediate effect on 06 operation. This Surveillance ensures the availability of high quality fuel oil for the DGs.

Fuel oil degradation during long tem ' storage shows up as an increase in particulate, due mostly to oxidation. The 3resence of particulate does not mean the fuel oil will not

) urn properly in a diesel engine. The particulate can cause fouling of filters and fuel oil injection equipment, however, which can cause engine failure.

Particulate concentrations should be determined in . {

accordance with ASTM 02276-[ ], Method A (Ref. 6). This !

method involves a gravinetric determination of total 1 particulate concentration in the fuel oil and has a limit of l 10 mg/1. It is acceptable to obtain a field sample for ,

subsequent laboratory testing in lieu of field testing. [For l those designs in which the total stored fuel oil volume s !

must be considered and tested separately.]

The Frequency of this test takes into consideration fuel oil degradation trends that indicate that particulate concentration is unlikely to change significantly between Frequency intervals.

" Diesel Fuel Quality Assurance Related to Standby Electrical Generators," Attendeec workshop included representatives from several nuclear power plants, the Nuclear Maintenance Applications Center (NMAC various laboratories and fuel service compa),nies. Topics discu included generator fuel systems, fuel contamination, fuel properties and significan specifications, laboratory tests, fuel monitoring, and additives. The attendees were a given demonstrations by two fuel cleaning companies.

planned for the week of May 7,1990. ~ A second workshop is already ASTM DEVELOPING NEW TEST FOR PARTICULATES IN DIESEL' FU The ASTM Committee which has responsibility for diesel and gas turbine fuel st cleanliness is D02.E.05. This group is in the process of developing a new test method f determining particulate contamination in diesel and gas turbine fuels. In most cases th test currently used for this purpose is ASTM Method D 2276.

The new test method will be essentially a modified version of D 2276. Using D 227i fuel. Jet fuel is a very clean fuel and so a large sample 2276 in order to obtain a measurable amount of particulate from the fuel. Th not the case with diesel fuel which tends to be much dirtier. As such, a smaller sam could be used with diesel and still produce accurate results, in fact a smaller sam should be used. A smaller sample size will reduce the test time and will also reduce; possibility that the test filters will become plugged before the entire sample has been diesel and gas turbine fuel. filtered. There will also be other modifications to th There will be a meeting of the task force working on this new test method at the December meeting of ASTM Committee D02 in New Orleans, LA at the Hyatt Hotel.

< NUCLEAR POWER PLANT DIESEL FUEL USER'S GROUP FORMING\

During the diesel fuel workshop several attendees voiced the desire to form a diesel user's group. This group would be a forum for sharing common problems and concern and, would be able to present a stronger, more unified position to regulatory agencies Representatives from NMAC and Southwest Research Institute were asked to initiate t planning for such a group.

As a result there will be an organization meeting at the upcoming ASTM meetings in New Orleans, LA. The organizational meeting will be held on the evening of Tuesday, December 12,1989, at the Hyatt Regency Hotel.
