1.0 INTRODUCTION
By correspondence dated June 9,1994 the staff of the Duquesne Light Company (DLC or the licensee) submitted a request to amend the operating licenses, DPR-66 and NPF-73 respectively, for Beaver Valley Power Station Units 1 and 2.
The amendment to each license seeks a change to Surveillance Requirement (SR) 4.8.1.1.2.d.l.d of the Beaver Valley Unit 1 and Unit 2 Technical Specifications (TSs).
The requested amendment, upon approval, will allow the licensee to change the qualitative " Clean and Bright" test for water and sediment content (ASTM Procedure D4176) to a quantitative method for testing water and sediment content (ASTM Procedure D1796).
The amendment request includes implementing any appropriate changes to the TS Bases Section.
The licensing basis for the nuclear industry has been established so that licensees are normally required by their TSs to periodically test the quality of diesel oil stored onsite.
One of the reasons for testing diesel oil stored onsite is to assure that the oil is not contaminated with excessive levels of water, sediment or particulates. Water in diesel oils can lead to corrosion products in carbon steel components, and can adversely impact combustion of the oil in the diesel cylinders. High levels of sediment and particulates in diesel oils can occlude fuel oil filters and lead to fuel starvation.
Licensees are required by TSs to declare any diesel generator as inoperable if
-the water, sediment or particulate level in the stored oil is determined to be above surveillance test acceptance limits.
Licensees are also normally required by TSs to sample and test all incoming shipments of fuel oil for quality. Tests on new oil typically include tests for specific gravity, flash point, kinematic viscosity, and water and sediment content.
In contrast to SRs on stored diesel oil, SRs on incoming diesel oil shipments require that licensees reject any batches of oil that fail to meet 9409140204 940908 PDR ADOCK 05000334 p
. the surveillance test acceptance criteria. The SRs on new fuel oil assure that any out-of-specification or contaminated diesel oil shipments will be prevented from being inadvertently added to the diesel oil storage tanks onsite.
Most licensees perform their tests on fuel oil samples in accordance with certain standard specifications or test methods issued by the American Society for Testing and Materials (ASTM). Typical ASTM test methods for fuel oil include those invoked in ASTM Standard Specification D975, entitled " Diesel Fuel Oils,", and tests for fuel oil parti ASTM Standard Test Method D2274 or 02276.pulate content, as defined in either D975 is a general standard for evaluating the quality of diesel fuel oils. The scope of 0975 is accomplished by invoking a series of ASTM Standard Test Methods commonly used for testing the quality of fuel oils. A list of the ASTM Standard Test Methods invoked in D975 is given in Table I of this Safety Evaluation; however, some of the standard methods include D445, " Test for Kinematic Viscosity of Transparent and Opaque Liquids (and the Calculation of Dynamic Viscosity);" 093, " Test for Flash Point by Pensky-Martens Closed Tester;" and D1796, " Test for Water and Sediment in Crude Oils and Fuel Oils by Centrifuge."
In 1992, the Environmental Protection Agency (EPA) enacted a rule (40 CFR 80.29) which required diesel fuel oil manufacturers or suppliers to mark any high sulfur content (> 0.05 wt. %), high aromatic content (> 35 vol. %), or high cetane index (> 40 cetane index) diesel oils with a blue dye (1,4 dialkylamino-anthraquinone).
Prior to implementation of the new EPA requirements, Grade 2-D diesel fuels were typically of a tinted amber color (light yellow-amber for fuels with ASTM color indexes of 0.5 or 1.0, moderate amber for fuels with ASTM color indexes of 1.5 or 2.0, and dark amber for fuel with ASTM color indexes of 2.5 or higher). Now, under the new EPA regulation, Grade 2-D oils would normally contain high sulfur or aromatic levels, and would be required to be manufactured with the blue dye.
EPA proposed 40 CFR 80.29 to prevent manufacturers, suppliers, or wholesalers of diesel fuel oils from selling undyed, high sulfur or high aromatic content diesel fuels to the automotive and trucking industries.
40 CFR 80.29 went into effect in October 1993. The rule was not enacted to affect the operation of emergency diesel i
generators at nuclear power generation facilities.
i 2.0 ' EVALUATION l
The TS requirements for determining water and sediment contents of diesel oil vary from plant to plant.
Some licensees are required by TSs to perform the quantitative test for water and sediment as defined in D1796. As stated previously, 01796 is invoked by D975 as the standard method for determining water and sediment contents in diesel fuel oils.
The method in D1796, which Henceforth,- for simplicity, all general ASTM Standard Specifications or Test Methods will be designated simply by their D-numbers, designated by Dxxx.
Specific editions of these Standard Specifications or Test Methods will be followed by a hyphenated two digit index, Dxxx-yy.
. is a quantitative method, uses centrifugation as a means of separating out water and sediment from the oil phase.
The acceptance criteria for D1796, as given in D975 Table 1, limit acceptable Grade 2-D diesel oils to a total water and sediment content of 0.05 vol. %.
Some licensees are required by TSs to perform the test defined in D4176, " Free Water and Particulate Contamination in Distillate Fuels (Clear and Bright Pass / Fail Procedures)," in lieu of the D1796 test.
In contrast to D1796, 0-4ri6 is a qualitative test.
The acceptance criteria in 04176 require the analyst performing the test to fail any diesel fuel sample exhibiting visible amounts of water or sediment or containing a " hazy" appearance.
However, the scope of D4176 is limited in that it applies only to fuel oils with ASTM color indexes of 5.0 or less (as defined in D1500, " ASTM Color of Petroleum Products").
When 40 CFR 80.29 initially went into effect in October of 1993, the blue dye was required to be mixed into the diesel oil at a concentration of 6 ppm. At this concentration, the dye darkens the tint of the oil and changes the color to a greenish, olive, or brownish hue.
Effective April 1, 1994, the dye concentration was required to be increased to 50 ppm.
The blue dye, at a concentration of 50 ppm, makes the fuel an extremely dark blue-black color.
In this case, any licensee required to perform a D4176, " Clear and Bright Test," on a freshly procured (dyed) oil sample would not be able to run the test since the fuel color would not fall within the scope of the procedure (i.e., be of an ASTM color index of 5.0 or less, as defined in D1500, " ASTM Color of Petroleum Products").
Dye in Grade 2-D fuel oil can also cause noncompliance with TS requirements if the licensing basis of the plant is such that the TSs require "a clear and bright appearance with proper color," or specifically limit the tint and color of the diesel fuel oil to a light-moderate amber or straw color, or to certain ASTM standard color numbers referenced in D1500.
TS 4.8.1.1.2.d.l. for Beaver Valley Units 1 and 2 requires the licensee to verify, prior to addition to the diesel fuel storage tanks, that new fuel oil has "a clear and bright appearance with proper color when tested in accordance with... D4176-82." Therefore, as currently licensed, the DLC is required to perform a " Clear and Bright Test," in accordance with D4176-82, on all incoming shipments of diesel fuel oil to the Beaver Valley Units 1 and 2.
According to TS SR 4.8.1.1.2.d.1, the licensee would be required to reject any shipment of high sulfur or aromatic content Grade 2-D diesel oil under either of the following conditions:
. the change in color and tint created by the dye has caused the fuel oil to fall outside the scope of D4176,
. the color and tint created by the dye is such of the fuel oil no longer meets the TS 4.8.1.1.2.d.1 requirement for " clear and bright appearance with proper color."
e l
- The licensee now proposes to perform the test for water and sediment delineated in D1796-83 in lieu of the 04176-82 test.
Since D975 has been approved by the staff as an acceptable general standard for evaluating the quality of diesel fuel oils in the industry, the staff continues to consider 01796 as an acceptable test method for determining water and sediment contents in diesel oils, and an acceptable alternative to D4176.
Therefore, the l
licensee's proposed amendment to use ASTM D1796-83 in lieu of ASTM D4176-82 is acceptable to the staff.
]
DLC's license amendment request submittal indicates that the alternative procedure, ASTM D1796-83, " Test for Water and Sediment in Crude Oils and Fuel Oils by Centrifuge," will prove an acceptable method of analyzing and determining the water and sediment content of all incoming shipments of diesel fuel oil onsite.
In this case, the licensee has shown that the change in ASTM procedures will not result in an unreviewed safety issue for the Beaver Valley l
Units 1 and 2, and therefore meets the acceptance criteria for implementing TS changes as defined in 10 CFR 50.59(c), 50.90, and 50.92.
The staff therefore finds that the changes to the TS proposed by the licensee are acceptable.
3.0 STATE CONSULTATION
In accordance with the Commission's regulations, the Pennsylvania State official was notified of the proposed issuance of the amendments.
The State official had no comments.
4.0 ENVIRONMENTAL CONSIDERATION
The amendments change a requirement with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20 and changes surveillance requirements.
The NRC staff has determined that the amendments involve no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendments involve no significant hazards i
consideration, and there has been no public comment on such finding (59 FR 34662). Accordingly, the amendments meet the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9).
Pursuant to 10 CFR 51.22(b) no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendments.

5.0 CONCLUSION
The Commission has concluded, based on the considerations discussed above, that:
(1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commission's regulations, 3
and (3) the issuance of the amendments will not be inimical to the common defense and security or to the health and safety of the public.
