Title | Inservice Testing of the Diesel Fuel Oil Transfer Piping |
Description | Unresolved Item. Inservice Testing of the Diesel Fuel Oil Transfer Piping. Introduction. The inspectors identified an unresolved item pertaining to the Unit 2 diesel fuel oil transfer piping being designated as safety-related, but was not in the inservice testing program. Description. The diesel fuel oil transfer piping from the vaults to the day tanks is safety-related, but is not included in the inservice testing program. Regulator
Guide 1.137, Fuel-Oil Systems For Standby Diesel Generators, Part C.e., states, i part, Section 7.3 of ANSI N195-1976 states that the arrangement of the fuel-oil syste shall provide for inservice inspection and testing in accordance with ASME Boiler an Pressure Vessel Code,Section XI, 'Rules for Inservice Inspection of Nuclear Powe Plant Components. For those portions of the fuel-oil systems for standby diese generators that are designed to Section III, Subsection ND of the Code, an acceptabl method of meeting the requirements of Section 7.3 is to ensure that the syste arrangement would allow: (1) Pressure testing of the fuel-oil system to a pressure 1.10 times the system design pressure at 10-year intervals. In the case of storage tanks, recommendations of the tank vendor should be taken into account when establishing the test pressure. (2) A visual examination to be conducted during the pressure test for evidence of component leakages, structural distress, or corrosion. In the case of burie components, a loss of system pressure during the test constitutes evidence o component leakage. The licensee has not entered the fuel transfer piping into the inservice testing program. The licensee is not fully committed to Regulatory Guide 1.137, but at the time of the inspection was unable to provide documentation to demonstrate an alternate method of meeting the ANSI N195-1976 requirements. The licensee was searching microfilm records for additional documentation and the inspectors have contacted NRR for additional guidance. This issue is being tracked as URI 05000368/2014003-06. |
