2.1 Type A Test

SUMMARY

Pressurization for the CILRT was started at 0045 hours5.208333e-4 days 0.0125 hours 7.440476e-5 weeks 1.71225e-5 months on April 20, 1983. A pressurization rate of approximately 4.5 psi per hour was maintained throughout the pressurization interval. Initial containment air temperature was approximately 74°F and the initial containment dew point temperature was approximately 65°F.

Containment pressurization was secured at 1131 hours0.0131 days 0.314 hours 0.00187 weeks 4.303455e-4 months on April 20, 1983, with a peak pressure of 61.385 psia.

Containment air temperature and dew point temperature at the start of the stabilization period were approximately 77°F and 68°F respectively.

The temperature stabilization criterion was satisfied at approximately 1604 hours0.0186 days 0.446 hours 0.00265 weeks 6.10322e-4 months on April 20, 1983. Over the next five hours, temperature increased by approximately 0.5°F. At 2104 hours0.0244 days 0.584 hours 0.00348 weeks 8.00572e-4 months on April 20, 1983, the contain~ent temperature became stable and showed little change over the next seven hours. During the early morning hours on April 21, 1983, river water temperature dropped approximately 2°F. This temperature drop was passed on to Component Cooling (CC)

System which supplies cooling water to the containment air recirculation fan cooling coils and to the Residual Heat Removal (RHR) System heat exchangers. This drop in CC temperature in turn affected containment air temperature causing it to drop approximately 0.3°F over a three hour period. At 0614 hours0.00711 days 0.171 hours 0.00102 weeks 2.33627e-4 months on April 21, 1983, CC was throttled in an attempt to offset the river water temperature drop.

During the test, Unit 2 was shutdown preparing for startup.

At .the time, the unit was on RHR which caused an increased load on CC. Due to CC being a. common system between both units, CC temperature stability was also affected by Unit 2 startup.

The inability to control containment air temperature, with the changes in CC temperature, complicated the determination of the actual leakage rate (See Attachments 2.lA and 2.lB).

Throughout the test, personnel performed searches to identify any leakage which might exist. During these investigations no significant sources of leakage were found. It was determined that the temperature effects were artificially inflating the leakage rate.

The reported leakage rate was based on a 28.333 hour0.00385 days 0.0925 hours 5.505952e-4 weeks 1.267065e-4 months test, running from 2104 hours0.0244 days 0.584 hours 0.00348 weeks 8.00572e-4 months on April 20, 1983, to 0124 hours0.00144 days 0.0344 hours 2.050265e-4 weeks 4.7182e-5 months on April 22, 1983. The calculated leakage rate satisfied the requirements of the procedure. For further discussion and

analysis of the leakage calculations, refer to Section 3.3 .

At 0214 hours0.00248 days 0.0594 hours 3.53836e-4 weeks 8.1427e-5 months on April 22, 1983, t.he mass pump-back verification test started. At 0400 hours0.00463 days 0.111 hours 6.613757e-4 weeks 1.522e-4 months , the mass pump-back test was completed. The verification test satisfied the requirements of the procedure.

Depressurization of the containment began at 0600 hours0.00694 days 0.167 hours 9.920635e-4 weeks 2.283e-4 months and was completed at 1708 hours0.0198 days 0.474 hours 0.00282 weeks 6.49894e-4 months on April 22, 1983 .

h. The Official Log of Events was established and available prior to commencement of the test.

i . Site meteorology data recorded for 7 days prior to and during the performance of the CILRT (Attachment 3.2A) .

3.2-1

3.2.2 Equipment and Instrumentation

Pressurization air dryer.

maintain of the containment was achieved by utilization of eight air compressors.* Air was piped through two aftercoolers in parallel and a refrigerated Instrumentation and valving were installed to proper monitoring and control during pressurization. The total capacity of the pres~urization system as installed was rated at 9,900 scfm.

During the test the necessary variables used to determine containment leakage were continually monitored using instrumentation which consisted of multiple resistance temperature detectors (RTDs), chilled mirror dew point indicators, and two absolute pressure quartz manometers (Attachment 3.2B). The general locations of the temperature and moisture sensors are shown in Attachments 3.2C and 3.2D.

A mass flowmeter in the service air system was used during the mass pump back verification test. All test instrumentation readings are input into the plant computer for data acquisition and averaging .

3.2-2

3.2.3 Data Acquisition System

The Surry Unit No. 1 CILRT utilized a Westinghouse Prodac P250 to scan, log, average, and a.nalyze data received from the containment instrumentation.

The P250 analog scan package reads all the analog inputs in a preestablished manner, converts these readings into engineering units, and then stores these values for use by the plant operators and by the plant application programs.

For the CILRT, the P250 Plant Computer monitored the following instrumentation:

~ Scan Rate (sec) 24 RTDs 20 5 chilled mirrors 20 2 quartz manometers 2 Instantaneous values of the CILRT instruments were recorded every 15 minutes during the test period, using the P250 digital trend function on the operator's console.

A 10-minute time average of the readings, calculated by the P250 Average and Integrate (A&I) package, was used as input in the plant computer CILRT programs .

The plant computer CILRT program consists of ILRTDATA, which runs every 10 minutes, collects A&I data for all the instrumentation, performs sensor validity checks, calculates weighted average dew point temperature, and vapor pressure, weighted average containment temperature, and containment air mass .

3.2-3

3.2.4 Data Resolution System

- After the appropriate data have been acquired and averaged, utilizing the plant computer system, the results are manually input to a remote computer system for leakage rate calculations.

Absolute Method of Mass Point Analysis The Absolute Method of Mass Point Analysis consists of calculating air masses within the containment structure, over the test period, from pressure, temperature, and dew point observations made during the CILRT. The air masses are computed using the ideal gas law as follows:

M = 144V (P-Pv) (Eq 1)

RT where:

M =airmass, lbm P = total pressure, psia Pv = average vapor pressure, psia R = 53.35 ft lbf/lbm 0 R (for air)

T = average containment temperature, 0 R V = .containment free volume, l .*8 x 10 6 ft 3

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 exQressed as a Qercentage of air mass lost in 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months or symbolically:

Leakage rate= (A/B) (-2400) (Eq 2) where A is the slope of the least-squares curve and Bis they-intercept. The sign convention is such that leakage out of the containment is positive and the units are in percent/day. The air mass is computed and the result is correlated as a function of time by means of a least-squares fit of the form:

m =At+ B (Eq 3)

The slope A and the y-intercept B are then used in Equation 2 to determine the leakage rate.

A 95 percent confidence interval is calculated using a Student's t distribution. The sum of the leakage rate and the 95 percent confidence interval is the UCL. The measured leakage rate may be described as 95 percent accurate to within the value of the UCL .

3.3 Test Results

3.3.1 Analysis of Test Results The test data for the period of 2104 hours0.0244 days 0.584 hours 0.00348 weeks 8.00572e-4 months on April 20, 1983, through 0124 hours0.00144 days 0.0344 hours 2.050265e-4 weeks 4.7182e-5 months on April 22, 1983, were analyzed for the final test results using VEPCO's time sharing computer program. The reduced input data, mass point analysis results, and the representative graphs are contained in Attachments 3.3A through 3.3E.

In order to evaluate the effect of the component cooling (CC) water temperature fluctuations on the containment air temperature and therefore on the reported leakage rate, the Type A test period has been divided into three distinct time periods. These time periods, or regions, are identified on the containment air temperature and air mass plots contained on Attachments 3.3C and 3.3D. The regions are as follows:

Region I - Depicts trend data from 2104 hours0.0244 days 0.584 hours 0.00348 weeks 8.00572e-4 months on April 20, 1983, to 0804 hours0.00931 days 0.223 hours 0.00133 weeks 3.05922e-4 months on April 21, 1983.

Region II - Depicts trend data from 0804 hours0.00931 days 0.223 hours 0.00133 weeks 3.05922e-4 months on April 21, 1983, to 1504 hours0.0174 days 0.418 hours 0.00249 weeks 5.72272e-4 months on April 21, 1983.

Region III - Depicts trend data from 1504 hours0.0174 days 0.418 hours 0.00249 weeks 5.72272e-4 months on April 21, 1983, to 0104 hours0.0012 days 0.0289 hours 1.719577e-4 weeks 3.9572e-5 months on April 22, 1983 .

The regions were determined primarily by observing the magnitude and algebraic sign of the slope of the containment air temperature plot. The temperature curve could easily be divided into more regions (as many as six) based entirely on slope, however three regions are sufficient to demonstrate the CC effect on the leakage rate.

The leakage rate of each region is summarized below:

Region Leakage rate (%/day)

I 0.066 II 0.116 III 0.038 This leakage rate is based on the total mass loss during each interval with a conversion to percent per day. The likelihood of obtaining an extended time period with an essentially constant temperature slope (due to Unit 2 Startup) was doubtful. Thus, the decision was made to use the entire twenty-eight hours as the reported leakage rate realizing that the actual leakage rate would be much lower .

3.3-1

The Absolute Method of Mass Point Analysis results for the reported containment leakage rate are 0.068774 percent per day. This satisfies the procedural acceptance criteria of 0.072 percent per day which is 0.075 percent per day less the Type C penalty for valves on systems not vented to the containment. The results, including corrections for Type Band C leakage, are outlined in Section 3.3.2.

The Type A test calculations were verified by the mass pump back method. The computer calculated air mass was within 0.25La of the metered mass, as shown in Section 3.3.3.

SECTION 4

LOCAL LEAK RATE TEST (TYPE BAND C)

Attachment 4A summarizes the Local Leak Rate Test (LLRT) data that was established to support the overall containment leakage testing program. Attachment 4B summarizes the leakage penalties added to the Type A overall leakage for systems that were either isolated or not vented and drained during the Type A Test, These LLRTs were performed by pressurizing the listed penetrations and either measuring leakage across the containment isolation valves (Type C) or across the resilient seals (Type B).

The acceptance criteria for Type Band C testing is in accordance with 10CFRSO, Appendix J (Reference LER 83-018). The combined leakage rate for all penetrations and valves, subject to Type B and C tests, is well below the acceptable leakage rate of 0.6 La or 165 scfh .
