SECTION 2

SUMMARY

2.1 TYPE A TEST

.Pressurization for the ILRT began at 0207 hours0.0024 days <br />0.0575 hours <br />3.422619e-4 weeks <br />7.87635e-5 months <br /> on June 7, 1985. Investi-gations 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 pressure was 67.92 psia when the pressurization equipment was secured at approximately 1102 hours0.0128 days <br />0.306 hours <br />0.00182 weeks <br />4.19311e-4 months <br />. The temperature stabilization criteria was satisfied at 2015 hours0.0233 days <br />0.56 hours <br />0.00333 weeks <br />7.667075e-4 months <br /> on June 7, 1985. This is slightly longer than the traditional Turkey Point temperature stabilization period of approximately eight hours. The additional time in achieving the temperature stabilization is attributed to the first. hour of pressurization when the cooling water to the compressor aftercoolers was found to be inadequate.

When sufficient flow was established, the quality of the compressed air improved.

The one hour of inadequate cooling water flow also impacted the moisture stabilization. The moisture trend did not achieve an essentially straight line trend until 0200 hours0.00231 days <br />0.0556 hours <br />3.306878e-4 weeks <br />7.61e-5 months <br /> on June 8, 1985. The start of the Type A was shifted to 0200 hours0.00231 days <br />0.0556 hours <br />3.306878e-4 weeks <br />7.61e-5 months <br /> based on moisture stabilization.

Both the Mass Point'nd the Total Time leakage rates were well below the Turkey Point 0.75La limit of 0.1875 percent per day. The stability in the leakage trends was interrupted at approximately 0715 and 0830 when the Spent Fuel Pit Heat Exchanger (SFPHX) was put in service. This, additional cooling load raised the component cooling water temperature which in turn raised the residual heat removal temperature. As shown on Attachment 2.1A, the impact on the containment air temperature was very subtle, however, the impact on the leakage trends, as shown on Attachment 2.1B, was dramatic. The start time of the Type A Test was shifted to 0830 based on the SFPHX temperature perturbation.

The temperature, humidity, and the pressure data were monitored at 15 minute intervals. The Type A Test was run from 0830 to 1630 hours0.0189 days <br />0.453 hours <br />0.0027 weeks <br />6.20215e-4 months <br /> on June 8, 1985, with a Mass Point Upper Confidence Limit (UCL-MP) of 0.069782 percent/day and a Total Time Upper Confidence Limit (UCL-TT) of 0.14049 percent per day (See Section 3.3, Test Results.) These rates are well below the 0.1875 percent day acceptance criteria.

The superimposed leakage verification test was started at 1730 hours0.02 days <br />0.481 hours <br />0.00286 weeks <br />6.58265e-4 months <br /> and was sucessfully completed at 2130 hours0.0247 days <br />0.592 hours <br />0.00352 weeks <br />8.10465e-4 months <br /> on June 8, 1985. Depressurization of the containment was started at 2207 hours0.0255 days <br />0.613 hours <br />0.00365 weeks <br />8.397635e-4 months <br /> on June 8, 1985, and was completed at 0608 hours0.00704 days <br />0.169 hours <br />0.00101 weeks <br />2.31344e-4 months <br /> on June 9, 1985.

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

The Local Leakage Rate Tests (LLRTs) of containment isolation valves and other primary containment penetrations were conducted as required by the methods described in FPSL's Operating Procedure No. 13404.1, "Containment Boundary Isolation Valves - Local Ieakage Rate Tests" since the last Unit No. 3 Type A Test performed in March 1982.

Section 4 of this report summarizes the data for the two surveillance periods (1983 and 1985) of LLRTs conducted since the last Type A Test in accordance with Appendix J, 10CFR50, Paragraph V.B.

GENERAL TEST DESCRIPTION 3.2.1 Prerequisites In accordance with the Turkey Point Plant Unit No. 3 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.

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.

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 10,000 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 (RTDs), ten relative humidity detectors (RHDs), and two absolute pressure quartz manometers. Pertinent data for the test instrumentation is listed in Attachment 3.2B, and the general locations of the RTDs and RHDs are shown in Attachment 3.2C through 3.2F.

A rotometer was used to perform the superimposed leakage verification test.

0830-1537101-B2 3-3

3.2.3 Data Acquisition System The Turkey Point Plant Unit No.. 3 ILRT sensor data were recorded at approximately 15 minute intervals during the test. A programmable, multicha'nnel data logger was used to scan and record data from 22 RTDs, 10 RHDs, and manometer signal inputs. Data readings of the flowmeter were manually recorded.

The ILRT utilized a portable programmable computer to average the test data.

Periodically during the test period, weighted average temperature, weighted average relative humidity, absolute pressure, 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 8 Webster Engineering Corporation's (SWEC) portable computer for leakage rate calculations. For the Turkey Point Plant Unit No. 3 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 masses within the containment structure, over the test period, using pressure, temperature, and dewpoint observations made during the ILRT. The air masses are computed using the ideal gas law as follows:

144 V (P-P )

v (Eq. 1)

RT where: M = air mass, lb m

P = total pressure, psia P = average vapor pressure, psia R = 53.35 ft-lb /lb m R (for air)

T = average containment temperature, R 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.

The air mass is calculated and correlated as a function of time by means of a least-squares curve fit of the form:

M = At, + B (Eq. 3) 0830-1537101-B2 3-4

The slope A and y-intercept B are 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 the 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 dewpoint observations made during the ILRT.

The containment air mass is computed using Equation l.

The measured leakage rate at any time (t) is 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:

Mi-Mt Measured leakage rate =

M..<)

Mi (b,t (2400) (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 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)

A is the slope and B is the y-intercept of the least-squares curve.

The confidence interval is calculated using 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 conjunction with the procedure.

SECTION 4 IOCAL LEAKAGE RATE TESTS (TYPES B and C)

Section 4 summarizes the LLRT data which has been obtained from periodic testing performed since the March 1982 Type A test. Pre-repair data are provided for surveillance testing performed in 1983 and 1985. These LLRTs were performed by pressurizing the listed penetrations with air and either measuring leakage across the containment isolation valves (Type C) or across the 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 or, in some cases, if the post-repair leakage is greater than the pre-repair leakage, then no it should be noted that certain penetrations repair was performed. Also, had multiple LLRT's performed as described 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 penetra-tions and valves subject to Types B and C tests in 1983 and 1985 were well below the acceptance criteria of less than 0.60 Ia.
