Background

SRP-LR Table 3.0-1, "FSAR Supplement for Aging Management of Applicable Systems," summary description provides an acceptable program description for the GALL Report AMP XI.M30, "Fuel Oil Chemistry," as per 10 CFR 54.21 (d). The FSAR Supplement includes the specific ASTM Standards used for monitoring and control of fuel oil contamination to maintain fuel oil quality.

Issue LRA Section A.1.15, "Diesel Fuel Monitoring," USAR supplement does not appear to include the specific industry standards used for the program. The current licensing basis will not be consistent with the staff-issued guidance document during the period of extended operation if the industry standards recommended by the GALL Report are not used.

Reguest Justify the apparent absence of the above mentioned industry standards in the USAR supplement for the Diesel Fuel Monitoring program. Alternatively, state the changes to the USAR supplement necessary to include the GALL Report recommended industry standards that will be used for the program.

Response

Changes to the previous response are shown with additions underlined.

Changes are provided to the USAR supplement to identify ASTM standards used in the monitoring and control of diesel fuel, specifically, ASTM 04057, 01796, 02274 and 02276.

The use of ASTM standard 01796 in lieu of ASTM 02709 is appropriate for RBS. ASTM 02709-96 states that Test Method 01796, "Standard Test Method for Water and Sediment in Fuel Oils by the Centrifuge Method (Laboratory Procedure)," is intended for higher viscosity fuel oils. The use of ASTM 02709-96 is limited to fuel oils within a specific viscosity and density range. However, a review of ASTM 01796 -83 and -04 reveals no limitation on its use due to viscosity or other fuel oil parameters that would impact its use at RSS. In addition, Section B.3.8.3 of the RBS Technical Specifications Bases provides a discussion in Surveillance Requirement 3.8.3.3 on fuel oil testing that states "Following the initial new fuel oil sample, the fuel oil is analyzed to establish that the other properties specified in Table 1 of ASTM 0975-81 (Ref. 6) are met for new fuel oil when tested in accordance with ASTM 0975-81 (Ref. 6)". ASTM 0975-81 states in Section 4.1.3 that water and sediment are determined in accordance with method 01796. This test method has been used at RBS for many years

RBG-47849 Page 2 of 2 in accordance with Technical Specification requirements. The use of ASTM 02709 in lieu of ASTM 01796 at RBS is unnecessary.

The changes to LRA A.1.15 and B.1.15 follow with additions underlined and deletions lined through.

[The following revised LRA sections are unchanged from the previous RAI response submitted on January 24, 2018.]

A.1.15 Diesel Fuel Monitoring The Diesel Fuel Monitoring Program manages loss of material in piping, tanks and other components in an environment of diesel fuel oil by verifying the quality of the fuel oil source.

This is performed by receipt inspection, sampling, and limiting the quantities of contaminants before allowing it to enter the fuel oil storage tanks. Parameters monitored include water and sediment content, total particulates, and levels of microbiological organisms in the fuel oil.

Monitoring and control are performed in accordance with ASTM standards 04057,01796, 02274 and 02276. The program includes multi-level sampling of fuel oil storage tanks.

Where multi-level sampling cannot be performed due to design, a representative sample is taken from the lowest part of the tank. A stabilizer/biocide is added to new fuel.
