3-2 3.2 GENERAL TEST DESCRIPTION
3.2.1 Prerequisites
In accordance with the Turkey Point Plant Unit No.4 ILRT Procedure 13100.1 (Reference 2), the following is a listing of the pertinent prerequisites that were completed and documented prior to containment pressurization:
a.General inspection of the accessible interior and exterior surfaces of the containment structures and components completed.
b.All equipment and instrumentation that could be damaged by test pressure removed or protected.
II c.All instrumentation required for the test.calibrated within six months of the test and functionally verified.d.All required system valve lineups completed, including closure of containment isolation valves.e.All required Types B and C local leakage rate testing completed.
f.The Official Log of Events established.
g.Site meteorological data recorded at least three days prior to and during the ILRT (Attachment 3.2A).h.Temporary containment air recirculation fans installed and tested.ILRT pressurization system properly installed and tested.All ILRT computer software used for test calculations tested and operational.
3.2.2 Equipment and Instrumentation Pressurization of the containment was achieved by the utilization of a temporary system consisting of ten air compressors manifolded to aftercoolers and refrigerant air dryers.The system included adequate instrumentation and valving to maintain proper monitoring and control of the compressed air quality throughout the pressurization sequence.The total capacity of the pressurization system was rated at approximately 11,000 standard cubic feet per minute (scfm).The various containment parameters required to calculate containment leakage during the test were monitored using instrumentation which consisted of 22 resistance temperature detectors (RTD's), 10 relative humidity detectors (RHD's), and an absolute pressure quartz manometer,.
Pertinent data for the test instrumentation is listed in Attachment 3.2B, and the general locations of the RTD's and RHD's are shown in Attachment 3.2C through 3.2F.A rotometer was used to perform the superimposed leakage verification test.3-3 3.2.3 Data Acquisition System The Turkey Point Plant Unit No.4 ILRT sensor data were recorded at approximately 15 minute intervals during the test.A programmable, multichannel data logger was used to scan and record data from 22 RTD's, 10 RHD's, and manometer signal inputs;Data readings of the rotometer were manually recorded.The ILRT utilized a portable programmable computer to average the test data.Periodically during the test period, weighted average temperature, air pressure, weighted average vapor pressure, and mass values were computed.3.2.4 Data Resolution System After the appropriate data had been acquired and averaged, the results were inputted to the Stone 6 Webster Engineering Corporation's (SWEC)portable computer for leakage rate calculations.
For the Turkey Point Plant Unit No.4 ILRT, both the Absolute Method of Mass Point Analysis and Absolute Method of Total Time Analysis were used to determine the leakage rate.Absolute Method of Mass Point Anal sis The Absolute Method of Mass Point Analysis consists of calculating the air mass within the containment structure, over the test period, using pressure, temperature, and relative humidity observations made during the ILRT., The air mass is computed using the ideal gas law as follows: M 144V(P-Pv)
RT (Eq.1)where: M~air mass, ibm P~total pressure, psia Pv~average vapor pressure, psia R~53.35 ft-lbf/lb R (for air)m 0 T average containment temperature, g 3 V containment free volume, 1.55 x 10 ft The leakage rate is then determined by plotting the air mass as a function of time, using a least-squares fit to determine the slope, A~dM/dT.The leakage rate is expressed as a percentage of the air mass lost in 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or symbolically:
Leakage Rate A/B(-2400)(Eq.2)Where A is the slope of the least-squares curve and B is the y-intercept.
The sign convention is such that the leakage out of the containment is positive, and the units are in percent/day, 3-4 (Eq 3)The air mass is calculated and the result is correlated as a function of time by means of a'least-squares curve fit of the form: M~At+B The slope A and y-intercept B are then used in Equation 2 to determine the leakage rate.A confidence interval is calculated using a Student's T distribution.
The sum of the leakage rate and confidence interval is the upper confidence limit-mass point (UCL-MP).Absolute Method of Total Time Anal sis The Absolute Method of Total Time Analysis consists of calculating air lost from the containment, using pressure, temperature, and relative humidity observations made during the ILRT.The containment air mass is computed using Equation 1.The measured leakage rate at any time (t)is then determined by subtracting the mass at that time (Mt)from the initial mass (Mi)and dividing by the initial mass.The measured leakage rate is expressed as a percentage of containment mass lost in 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or symbolically:
Measured Leakage Rate Mi-Mt (2400)Mi (>t)(Eq.4)The sign convention is such that leakage out of the containment is positive, and the units are in percent/day.
The calculated leakage rate is then determined by plotting the measured leakage rate as a function of time and then performing a least-squares curve fit of the measured leakage rate values as follows: Calculated Leakage Rate At+B (Eq.5)where, A is the slope and B is the y-intercept of the least squares curve.The confidence interval is calculated in accordance with the'equations in Reference 5.The sum of the calculated leakage rate and the confidence interval is the upper confidence limit-total time (UCL-TT).This analysis method was used in con)unction with procedure 13100.1 (Reference 2).3-5 ATTACHMENT 3.2A SITE METEOROLOGY Date 3-23-86 3-24-86 3-25-86 Time 1700 1800 1900 2000 2100 2200 2300 0000 0100 0200 0300 0400 0500 0600 0700 0800 0900 1000 1100 1200 1300 1400 1500 1600 1700 1800 1900 2000 2100 2200 2300 0000 0100 0200 0300 0400 0500 0600 0700 0800 0900 1000 1100 1200 1300 1400 Ambient Temperature (p 69 68 66 66 64 63 62 60 58 56 56 56 57 57 57 57 58 61 64 70 72 70 71 72 71 69 65 65 65 65 65 66 66 66 66 66 66 66 65 68 71 70 71 73 74 72 Page 1 of Barometric Pressure 30.36 30.37 30.38 30.40 30.40 30.41 30.42 30.40 30.37 30.37 30.36 30.36 30.37 30.37 30.40 30.44 30.46 30.48 30.48 30.47 30.47 30.42 30.41 30.40 30.41 30.42 30.43 30.43 30.45 30.45 30.45 30.45 30.42 30.40 30.38 30.36 30.25 30.40 30.41 30.43 30.45 30.33 30.33 30.31 30.30 30.25 Wind Velocity~(m h)11 8 5 10 6 9 12 10 12 12 7 ll 6 8 12 10 10 5 6 8 10 10 12 7 8 7 8 4 12 5 6 5 6 5 6 7 12 12 16 13 12 15 13 13 12 10 Wind Direction~(a z emu th 300 330 335 335 330 330 320 315 335 320 325 325 355 325 330 330 330 330 330 40 70 60 63 65 45 45 65 64 63 55 55 55 55 60 70 79 90 91 91 90 90 85 90 85 85 75 ATTACHMENT 3.2A (Continued)

SECTION 4 LOCAL LEAKAGE RATE TESTS (TYPES B AND C)Section 4 summarizes the LLRT data which has been obtained from periodic testing performed since the Hay 1983 Type A ILRT.Pre-repair data are provided for surveillance testing performed in 1984 and 1986.These LLRT's were performed by pressurizing the listed penetrations with either air or nitrogen and measuring the leakage across the containment isolation valves (Type C)or resilient seals (Type B).Each penetration's leakage rate can be obtained from site reference material.If the pre-repair and post-repair leakages are the same then no repair was performed.
Also, it should be noted that certain penetrations had multiple LLRT's performed as indicated in Attachments 4A and 4B.The acceptance criteria for Types B and C testing are in accordance with 10CFR50, Appendix J.The combined"as-left" leakage rate for all penetrations and valves subject to Type B and C tests in 1984 and 1986 were well below the acceptance criteria of less than 0.60 La.The data contained in this section are summarized below: Attachment Title 4A 4B 4C 1986 Local Leakage Rate Test Data 1984 Local Leakage Rate Test Data 1986 Local Leakage Rate Test Summary Analysis I 4-1 ATTACHMENT 4A 1986 LOCAL LEAKAGE RATE TEST DATA Penetration No.5 PRT to Gas Analyzer 6 Nitrogen to PRT 7 PW to PRT and RCP Standpipes Type Test Equipment/Valves Tested CV-516 (OSC)SV-6385 (OSC).CK-518 (ISC)CK-519 (ISC)CV-519A (OSC)CV-519B (ISC)CV-522A (ISC)CV-522B (ISC)CV>>522C (ISC)Pre-Repair Leakage (cc/min)425 425 70,000 540 (25 Combination

SUMMARY
ANALYSIS The pre-repair LLRT, the repair, and the post-repair LLRT for each boundary, or penetration, was reviewed.The net leakage contribution for each penetration was determined using the following criteria: 1.A leakage equivalent to the repair improvement achieved on each valve in the penetration is calculated.
2.The leakage equivalent is the difference between the pre-repair and the post-repair LLRT results.,3.If a repair was not performed, a zero leakage equivalent is assessed to the valve.4.The leakage equivalent assessed to a penetration may be reduced due to the safety related service of the system associated with the penetration(s).
Justification for this reduction will be provided with the analysis.5.The net equivalent leakage for the penetration is the lowest of the inside or outside valve grouping (e.g., simulates minimum pathway leakage).6.If the"As-Left" leakage of a repaired valve is lower than the"As-Left" leakage of a valve that didn't require a repair, then the penetration net equivalent leakage is the difference between the"As-Left" leakages.7.For series valves tested together, the penetration net equivalent leakage is half the total leakage when both valves are repaired at the same time (prior to performing another test).8.When the summation of the leakage equivalent and the leakage measured during a successful Type A test is greater than 0.75 L the penetration(s) with excessive leakage(s) shall be analyzed under a corrective action program.Page 1 of 5 ATTACHMENT (Continued) 1986 LLRT SU&fARY ANALYSIS Pen.No.Valve Loc."As-Found""As-Left" Pen.(ccm).(ccm)Net Remarks 5-PRT to Gas Analyzer-Nitrogen to PRT RCP Standpipes CV-516 SV-6385 CK-518 CK-519 OSC OSC ISC ISC Z 25 (25 70,000 540 (25 (25 170 370 540 10 14-PW to PRT and RCP Standpipes

If piece-wise maintenance had been performed; as was done on Penetration 36, a smaller net equivalent leakage~mi ht have resulted.2.Greater than represents the largest flowmeter used for the 1986 LLRT program.See Penetration 36.CONCLUSION The net equivalent leakage is 21,850 ccm, or 0.071860 percent/day.
