A.C. SOURCES and DNSITE POWER DISTRIBUTION SYSTEMS The OPERABILITY of the A.C. and D.C. power sources and associated distribution systems during operation ensures that sufficient power will be available to supply the safety related equipment required for (1) the safe shutdown of the facility and (2) the mitigation and control of accident conditions within the facility.
The minimum specified independent and redundant A.C. and D.C. power sources and distribution systems satisfy the requirements of General Design Criteria 17 of Appendix A to 10 CFR Part 50.
The ACTION requirements specified for the levels of degradation of the power sources provide restriction upon continued facility operation commensurate with the level of degradation. ACTI0f1 statements have been included in the specification to cover all situations where either one A.C.
source or a cambination of two A.C. sources are inoperable.
ACTI0fl statements c, e, and f are intended to be followed to completion once entered and should not be exited until both A.C. sources are restored.
The OPERABILITY of the power sources are consistent with the initial condition assumptions of the accident analyses and are based upon maintaining at least Division I or 11 of the onsite A,C. and D.C. power sources and associated distribution systems OPERABLE during accident conditions coincident with an assumed loss of offsite pov,er and single failure of one of the two onsite A.C. sources.
Division 111 supplies the high pressure core spray (HPCS) system only.
The OPERABILITY of the minimum specified A.C. and D.C. power sources and associated distribution systems during shutdown and refueling ensures that (1) the facility can be maintained in the shutdown or refueling condition for extended time periods and (2) sufficient instrumentation and control capability is available for monitoring and maintaining the unit status, i
The surveillance requirements for demonstrating the OPERABILITY of the diesel generators are in accordance with the recommendations of Regulatory Guide 1.9, " Selection of Diesel Generator Set Capacity for Standby Power Supplies," March 10, 1971, with the exception noted in Appendix B to the FSAR, and Regulatory Guide 1.108, " Periodic Testing of Diesel Generator Units Used as Onsite Electric Power Systems at fluclear Power Plants," Revision 1, August 1977.
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 immediate, detrimental impact on diesel engine combustion / operation.
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.
The tests, limits, and applicable American Society for Testing Materials (ASTM) standards are as follows:
a.
Sample the new fuel oil in accordance with ASTM-D4057-88; b.
Verify in accordance with the tests specified in ASTM-D975-88 that the l
sample has a water and sediment content of less than or equal to 0.05 l
volume percent and a kinematic viscosity at 40 *C of greater than or equal j
to 1.9 but less than or equal to 4.1.

3/4.8 ELECTRICAL POWER SYSTEMS RASES A.C. SOURCES and ONSITE POWER DISTRIBUTION SYSTEMS (Continued) c.
Verify that the new fuel oil has a total particulate contamination of less than 10 mg/ liter when tested in accordance with ASTM-D2276-89.
This surveillance is an integral part of a comprchensive program to ensure the availability of high quality fuel oil for the diesel generators at all times.
By testing for particulate on a 31-day basis, information regarding the condition of stored fuel oil can be obtained and trended.
fuel oil degradation during long term storage shows up an increase in particulate, due mostly to oxidation.
The presence of particulate does not mean the fuel oil will not burn properly in a diesel engine. The particulate can cause fouling of filters and fuel oil injection equipment, however, which can cause engine failure.
If particulate is removed from stored fuel oil by circulating to oil through filters (other than diesel engine filters), the fuel oil can be restored to acceptable condition and its storage life extended indefinitely.
By obtaining and trending particulate data, it is possible to determine when stored fuel oil cleanup will be necessary.
This is done before the maximum allowable particulate concentration is reached.
Particulate concentrations should be determined in accordance with ASTM-D2276-89, Method A.
This method involves a gravimetric determination of total particulate concentration in fuel oil and has a limit of 10 mg/1.
It is acceptable tn obtain a field sample for subsequent lab testing in lieu of field testing.
In the case (s) where the total stored fuel oil volume is contained in two or more interconnected tanks, each tank must be considered and tested separately.
The frequency of this surveillance takes into consideration fuel oil degradation trends that indicate that particulate concentration is unlikely to change between frequency intervals.
There is no quantitative data regarding the capability of diesel engines to operate for prolonged periods of time with fuel oil particulate contamination in excess of 10 mg/1. Therefore, if this limit is reached, the associated diesel generator shall be declared inoperable.
In practice, however, this should not present a problem since the concept behind this surveillance requirement is to establish fuel oil degradation trends, which will provide an alert to the need for corrective action prior to impacting on diesel generator operability.
The diesel generators are equipped with a pre-lubrication system which maintains a continuous flow of oil to the diesel engine moving parts while the engine is shutdown. The purpose of this system is to increase long term diesel generator reliability by reducing the stress and wear caused by frequent dry starting of the diesel generator.
The diesel generator pre-lube may be accomplished either through, normal operation of the installed pre-lubrication system, or ty manual pre-lubrication of the diesel generator in accordance with manufacturers instructions.
Performance of an idle start of the diesel generator is not considered to be a means of pre-lubrication.
