(ANSI) Standard N510-1975, Testing of Nuclear Air Cleaning Systems, during.the performance of Standby Gas Treatment . (SGT) . System surveillance testing.                                                            . Technical Specification (TS) _3.7.B.2.a states that SGT high efficiency particulate air (HEPA) filter performance testing shall-be performed in accordance with ANSI N510-1975'. The. standard prescribes air-aerosol distribution criteria for dioctyphthalate (DOP) challenge aerosol' upstream and-downstream of the HEPA filter under test.
                          ~Although TVA has determined that the DOP distribution criteria of~the ANSI standard were not met by the Surveillance Instruction, subsequent testing has confirmed that the SGT HEPA filters meet the leakage requirements-of the TS.
                            .TVA is reporting this event in pursuant to 10' CFR 50.73 (a) (2) (i) (B), as a condition prohibited by plant Technical Specifications.
