SUMMARY

2.1 TYPE A TEST Pressurization for the ILRT began at 2356 hours0.0273 days <br />0.654 hours <br />0.0039 weeks <br />8.96458e-4 months <br /> on March 25, 1986.

Investigations of all penetration areas for leakage were conducted during

the pressurization period and throughout the Type A test. Only minor leakage paths were identified.

Containment pressurization equipment was secured at approximately 0937 hours0.0108 days <br />0.26 hours <br />0.00155 weeks <br />3.565285e-4 months <br /> on March 26, 1986, with a peak instantaneous pressure of 67.148 psia.

Temperature, humidity, and pressure data was continuously recorded throughout the entire test period at 15 minute intervals. The temperature stabilization criteria was satisfied at 1915 hours0.0222 days <br />0.532 hours <br />0.00317 weeks <br />7.286575e-4 months <br /> on March 26, 1986.

The Type A test was successfully completed from 1930 hours0.0223 days <br />0.536 hours <br />0.00319 weeks <br />7.34365e-4 months <br /> on March 26, 1986 to 0500 hours0.00579 days <br />0.139 hours <br />8.267196e-4 weeks <br />1.9025e-4 months <br /> on March 27, 1986, with a Mass Point Upper Confidence Limit (UCL-MP) of 0.083594 percent/day and a Total Time Upper Confidence Limit (UCL-TT) of 0,108892 percent/day, (See Section 3.3, Test Results).

Both the Mass Point and the Total Time leakage rates were well below the Turkey Point 0.75 La acceptance criteria of 0.1875 percent per day.

The Type A test duration was extended by. approximately one and one-half hours. This, was done 'to closely monitor the slight change in the mass trend which occurred at approximately midnight of March 26, 1986.

Reference the mass and leakage rate graphs of Attachments 3.3D through 3.3F.

A review of Attachment 3.3A indicates that at approximately 2330 hours0.027 days <br />0.647 hours <br />0.00385 weeks <br />8.86565e-4 months <br /> on March 26, 1986 (which is 4.250 hours0.00289 days <br />0.0694 hours <br />4.133598e-4 weeks <br />9.5125e-5 months <br /> after the start of the Type A test),

the temperature and pressure trends essentially stabilized. This brought about a very slight change in the mass trend. Once additional data was obtained it was readily determined that a significant break in the trends had not occured. A subsequent review of all the individual sensor readings did not reveal any abnormalities.

The superimposed leakage verification test was started at 0630 hours0.00729 days <br />0.175 hours <br />0.00104 weeks <br />2.39715e-4 months <br /> and was successfully completed at 1115 hours0.0129 days <br />0.31 hours <br />0.00184 weeks <br />4.242575e-4 months <br /> on March 27, 1986. The results of the verification test satisfied the requirements set forth in References 4 and 5, (See Section 3.3, Test Results).

Depressurization of the containment commenced at 1200 hours0.0139 days <br />0.333 hours <br />0.00198 weeks <br />4.566e-4 months <br /> on March and was completed in the early evening. 27,'986 2-1

1 2.2 LOCAL LEAKAGE RATE TESTS (Types B and C)

The Local Leakage Rate Tests (LLRT's) of containment isolation valves and other primary containment penetrations were conducted as,.required by the methods described in FP&L's Operating Procedure No. 13404.1, "Containment Boundary Isolation Valves Local Leakage Rate Tests" since the last Unit No. 4 Type A Test performed in May 1983.

Section 4 of this report summarizes the data for the two surveillance periods (1984 and 1986) of LLRT's conducted since the last Type A Test in accordance with Appendix J, 10CFR50, Paragraph V.B.

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/lbm R (for air) 0 T average containment temperature, V containment free volume, 1.55 x 10 g ft3 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

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 (Eq 3)

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) (Eq. 4)

Mi (>t)

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).

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:

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.

1. Since both valves were reworked at the same time, one-half of the total leakage (As-Found minus As-Left) is conservatively assigned to this penetration. 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.
