PRECAUTIONS 1.
Warning signs shall be pusted at convenient locations around the periphery of the test area. All personnel not perfoming any required duties shall restrict their access beyond these points.
2.
All station radiation protection and safety practicas and rules will be strictly followed for this test.
3.
All requests for equipment out-of-service for repairs during the test must be evaluated with respect to the fact that the primary centainment will be under approximately 48 psig.
4.
At no time during the period of pressurization, at test pres-sure, or depressurization of the primary containment will travel of the reactor building crane be allowed over the reactor cavity area.
5.
If use of the shutdown cooling system is anticipated at ;ay-time during the test, it shall be run for the entire duration of the test. This is to avoid transients in the vessel water level. A vessel water temperature of approximately 135*F shall be maintained.
\\
NOTE If shutdown cooling is run, one branch shall be put in service, but the vessel shell temperature shall not be allowed to drop below 120*F or go above 200*F and shall vary less than 5'F during the test.
When using shutdown cooling with the reactor recirculation pumps not running, either the recirculation pump suction valve (MO-202-4A or B) or discharge valve (M0-202-5A or B) and (MO-202-7A or 8) must be closed in order to insu*e that flow is es-tablished through the reactor ves-sel and not through the idle pump.

LIMITATIONS AND ACTIONS 1.
The integrated leakage rate test will be conducted by pressurizing the primary containment to a pressure of at least the calculated maximum peak a:cident pressure of 48 psig.
2.
After the preoperational leakage rate tests, a set of three type A tests shall be performed, at approximately equal in-tervals during each ten year service period. The third test of each set shall be conducted when the unit is shutdown for the ten year inservice inspections.
3.
Successful completion of this test will obtain all of the data necessary to demonstrate the integrity of the primary containment consistent with all station, license, and Nuclear Regulatory Commission requirements.
a.
The indicated leak rate shall be less than Lt (75% La).
b.
The upper 95 confidence limit of the indicated leak rate, whien includes appropriate consideration for ran-dom measurement errors, shall also be less than Lt (75% La).
4 Drywell pressurization will be discontinued if leakag: above the maximum allowable rate is obvious or the drywell pressure cannot be increased. Repairs will be made and the test re-started.
NOTE Before terminating the test, a leak rate must be determined for report-ing to tne NRC.
If the test is thus terminated, a Reportable Occurrence must be issued.
5.
During the period between the initiation of the containment inspectiori and the performance of this Type A test, no re-pairs or adjustments shall be made so that the containment can be tested in as close to the "as is" condition as prac-tical.
6.
During the period between the car.pletion of one Type A test and the initiation of the containment inspection for the sub-sequent Type A test, repairs or adjustments shall be rade to components whose leakage exceeds that specified in the Tech-nical Specifications as soon as practical after ide itification.

DTS 1600-7 Revision 5 7.
If ouring a Type A test, including the supplemental induced leakage test, potentially excessive leakage paths are iden-l tified which will interfere with satisfactory completion of the test, or which result in the Type A test not meeting the acceptance criteria, the Type A test shall be teminated and the leakage through such paths shall be measured using local leakage testing methods. Repairs and/or adjust:nents to equip-ment shall be made and the Type A test restarted. The cor-rective action and the change in leakage rate detemined from the tests and overall integrated leakage detemined from the local leak and Type A tests shall be included in the report submitted to the Cerimission.
8.
Closure of containment isolation valves for the Type A test shall be accomplished by normal operation and without any preliminary exercising or adjustments. Repairs of malopera-ting or leaking valves shall be made as necessary.
Informa-tion on any valve closure malfunction or valve leakage that requires corrective action before the test, shall be included in the report submitted to the Commission.
9.
The containment test conditions shall be allowed to stabilize for a period of at least four hours after initial pressurization.
Refer to Step F.2.g. (Pressurization and Stabilization).
10.
All vented systems shall be drained of water or other fluids to the extent necessary to assure exposure of the system con-tainment isolation valves to containment air test pressure and to assure that they will be subjected to the post-acci-dent differential pressure. Systems that are required to maintain the plant in a safe condition during the test shall be operable in their nomal mode, and need not be vented.
Systems that are normally filled with water and operating under post-accident conditions, such as the containment heat removal system, need not be vented. Refer to Table 1, list of non-vented systams.
11.
Results of the supplementai induced leakage test are accept-able provided that the difference between the supplemental test data and the Type A test data is within 0.25 La:

Revision'5 12.
A general inspection of the accessible interior and exterior surfaces of the primary containment stracture and components shall be perfomed prior to any Type A test to uncover any evidence of structural deterioration which may affect either the containment structural integrity or leak tightness.
If there is evidence of structural deterioration, Type A tests shall not be perfomed until corrective action is taken. Such structural deterioration and corrective actions taken shall be reported as part of the test report.
13.
If the shutdown cooling system is required due to the reactor decay heat, it shall remain in operation throughnut the test.
This will help prevent transients in reactor water level.
NOTE When using shutdown cooling with the reactor recirculation pumps not running either the recircula-or 8) pump suction valve (M0-20?-4A tien or discharge valves (M0-402-SA or B and M0-202-7A or B) must be closed in order to insure that flow is established through the reactor vessel and not through the idle pump.

48 psig Induced Leak Rate Phase (Phase 4).
i Phase 4 is the induced leakage portion of the ILRT. During this test, a deliberate leak of known magnitude will be su-perimposed on the leakage rate already calculated during the phase 3.
This will provide reassurance against any uncertain-ties associated with the performance of the leak rate test.
This leak should be of the same magnitude as phase 3 calculated leak rate.
ihe new leakage rate is then calculated and should approximately equal phase 3 leakage rate plus the induced leakage rate. This phase then acts as a verification of the accuracy of the data obtained in phase 3.

Pretest Requirements 1.
Arrange for the calibration of the instrumentation to be used.
Verified 2.
Make a survey of the primary containment for the purpose of establishing any tendencies for regional variations in temp-eratu re. This survey will be u ed in determining where to place the temperature sensing devices.
Verified NOTE Where testing experience with a given containment structure has previously established appropriate locations for temperature sensors, temperature surveys may be eliminated.
3.
At the same time as the temperature survey, conduct a survey for the purpose of detemining the placement of the humidity indicators so that a representative sampling of the primary containment air can be made.
Verified NOTE As in the case of the temperature survey, this humidt ty survey may be eliminated for a containment structure which has known and char-acteristic humidity patterns.
4.
Determine the placement of all temperature and humidity sensing devices from the surveys in steps 2 and 3 above.
Verified 5.
Obtain the instrument accuracies for all instruments and read-out devices to be used in the ILRT.
Perfonn an error analysis to verify that the accuracy of the collected data is consistent with the magnitude of the specified leakage rate. This analysis must be done prior to the placement of any instrumentation in the primary containment for the test. (See Appendix A, attached, for a sample calculation.)
APPROVED FEB 16'83 48 of 77 D.O.S.R.
DTS 1600-7 Revision 5 INTERPRETATION Specifically, the combined instr-ument repeatability error should be less than 2ET, of La, the maximum allowable leak rate.
Verified 6.
Arrange for the availability of the air compressors for use in pressurizing the containment.
Verified 7.
Examine LLRT results for all tests and verify that all Tech-nical Specification limits have been met prior to the start of the ILRT. Also, obtain the total calculated leakage fran the primary containment penetrations both prior to and after repairs (in the case of double gasketed seals, before and after opening the seal). This information will be required when the results of the ILRT are analyzed.
Verified 8.
Arrange with the Instrument Mechar.ics for placement of the calibrated instrumentation in the primary containment and its connection to read-out devices outside the primary containment.
Verify the location and operability status of the instrumentation.
Verified 9.
Verify the availability of instrumentation for the recording of ambient changes in the reactor building. These devices need only be of such accuracy that they will indicate gross barometric variations for correlation to test results.
Verified 10.
Determine the volume of the primary containment associated with each temperature and humidity sensing device. This information will be used during the test for volume weighting the data.

CALCULATED LEAK 2 ATE The method of "Least Squares" is a statistical procedure for finding the best fitting regression line for a set of v:3sured da ta. The criterion for the best fitting line to a set of data points is that the sum of the squares of the deviations of the observed points from the line must be a minimum. When this critarion is met, a unique best fitting line is obtained based on all of the data points in the ILRT. The value of the leak rate based on the regression is called the statistically average leak rate.
Since it is assumed tnat the leak rate is constant during the testing period; a plot of the measured contained dry air mass versus time would ideally yield a straight line with a negative slope (assuming 6 non-zero leak rate). Obviously, sampling techniques and test conditions are not perfect and consequently the measured values will de/iate from the ideal straight line situation.
Based on this statistical process, the calculated leak rate is obtained from the equation:
L9=Aj+89 g

95% CONFIDENCE LIMITS To detemine the value of the confidence limits the following statistical infomation is required; the variance, standard deviation, and students' T-distribution.
3:. SSO n-2 where SSQ =
(M9 - L )2 g
S2 variance
=
S standard deviation based (n-2) degrees of
=
freedom.
The standard deviation has more practical significance since computing the standard deviation returns the measure of variability to the original units of measurement. Addi tionally, it can be showr, that given a nomal distribution of measurements, approximately 95%
of the measurements will fall within two standard deviations of the mean.
The number of standard deviations either side of the regression line which establish a 95% confidence interval are more accurately determined using a statistical table called a " Table of Percentage Points of the T-Distribution" and provide increased confidence in outcomes for small and large sample sizes.
The Table of T-Cistributions has been fomulized for use by the computer program as follows:
TD = 1.95996 + 2.37226, 2.8225 (n-2)
(n-2)2 where TD = value of T-Distribution for the 95% confidence limit and (n-2) degrees of freedom.
