2.1 2.1.1 2.1.2 2.2 2'This test shall be performed every 18 months or following painting, fire, or chemical release, in the area communicating with the air handling unit and shall have the following conditions demonstrated:
Pressure drop across the<<HEPA<<filter bank is<3<<H 0 at design flow rate, (+104).In place thermally generated<<DOP<<testing.of the<<HEPA<<filters shall show>994 removal efficiency.
Test shall be performed after each complete or partial replacement of the<<HEPA<<filter bank or after any structural maintenance performed on the hepa mounting frames or housing.Visual inspection of<<HEPA<<filter assemblies for damage and for freedom of dust accumulation, shall be performed.

4.1 Vendor documentation required by the applicable purchase order has been.submitted to QC Dept.and found acceptable prior to start of work.QC 4.2 Ensure an A-52.4 has been initiated for the unit to be tempted, or the plant is in Cold Shutdown with Tavg 200 F.4.3 RGGE test personnel are qualified in accordance with A-1102.4.'4 Notify Shift Supervisor and Head Control Operator at start of test.4.5 When mass air flow thru"HEPA" bank(s)has been determined, log on applicable vendor's"IN-TEST" data sheet(s).4.6 4~6~1 This procedure is divided into the following sections.Initial which section(s) apply and mark remainder N/A.Hepa Filter Bank Visual Inspection (Section 6.2).4.6.2 Hepa Filter Bank Testing-DOP (Section 6.3).4.6.3 Hepa Filter Bank Removal and Replacement (Section 6.4).
4~7 Prepare test tags for the following:
PT-47.5:3 POSITION PRIOR TO TEST: "AS REQUIRED FOR TEST"<tREMOTEn POSITION RE UIRED: 4.7.1 MCB EMERG.STA."A" Recirc.Fan Switch: MCB EMERG.STA.4.7.2"B" Recirc.Fan Switch: 4.7.3"C" Recirc.Fan Switch: 4.7.4"D" Recirc.Fan Switch: 4.'8 Notify HP Dept.that system will be shutdown to facilitate entry into unit for inspection.and test preparation.
4.9 SWP has been issued.4.10 If a discrepancy requiring maintenance is found, submit a WR/TR to correct the problem.4.11 4.12 Notify QC Dept.prior to start of test.Notify Chemical Control to ensure"Ginna Station Consumable Material Labels" are available to be posted on all chemical containers used for this test.4.12.1 A Restricted Use Permit has been issued for the listed products: 4~12.1.1 PRODUCT: DXOCTYL PHTHALATE DOP~PERMIT 90:173P 5.0 PRECAUTIONS
'.1 Radiation protection practices will be observed at all times.
PT-47.5:4 5.2 Normal company work safety practices will be observed at all times.5.3 5.4 Notify the Health Physics Section that DOP will be used to test the recirculation unit Hepa Filters and a strong organic odor may be noticed in the areas affected by this system.Proper sequential implementation of each process in this procedure, as approved, is necessary to ensure adherence to A-805, Control of Consumable Materials, at Ginna Station.6.0 INSTRUCTIONS:
NOTE: These instructions are common for all four hepa banks and will be repeated when testing each individual unit.Steps may be marked N/A, if any unit is not being tested at this time.Recirc.Units"A" II B II C II D lf 6.1 Ensure associated fan is shutdown (" Pull-Stop" position)and test tag(s)are hung on fan switch(es), before entering plenum unit (MCB and Emerg.Sta.).6.2 HEPA FILTER BANK VISUAL INSPECTION:

Connect DOP Detector to upstream sample line, allow reading to stabilize, record reading on vendor's"DOP TEST" data sheet, and disconnect sample line.Connect DOP Detector to downstream sample line, allow reading to stabilize, record reading, and disconnect sample line.
PT-47.5:6 Recirc.Units II A II II B II"D" 6.3.10 Repeat Step 6.3.8 to ensure that upstream concentration has remained the same, (+5).6.3.11 Calculate percent efficiency and transfer data to appropriate vendor's data sheet.EFFZCZENCY:
6.3.12 Zf a discrepancy requiring maintenance is found, due to the percent efficiency obtained being less than the allowable limits, submit.a WR/TR to correct the problem as soon as practical and retest, otherwise mark N/A.RETEST EFFZCIENCY:
6.3.13'emove all DOP equipment hoses from sample points.6.3.14 Replace all pipe caps and fittings on unit.6.4 HEPA FILTER BANK REMOVAL AND REPLACEMENT 6.4.1 Ensure instruction Step 6.1 has been performed prior to entering plenum unit.6.4.2 Number of filter cells removed.¹¹6.4.3 Replace filter cells removed with approved type and ensure the bank is restored to operating condition.
6.4.4 Test system utilizing appropriate test section to ensure system efficiency within allowable limits.6.5 A copy of the vendor's test data shall be attached to this procedure.
6.6 Vendor to submit, at a future date, a complete report of test results.6.7'nsure all test tags have been removed and test tag log reflects so.
