SUMMARY
l 1
The periodic Integrated Leak Rate Test (ILRT) of Prairie Island Unit 2 Containment-was completed April 21, 1989. This
. leakage rate test was-performed in accordance with Prairie Island Technical Specification 4.4.A, 10CFR50 Appendix J,
~*
and ANSI N45.4-1972. In addition, ANSI 56.8-1981 Mass Point calculation technique was used to analyze the data.
' The test After psig. was performed initial at reduced pressure,.P[n, pressurization ment wasequal to 23 the conta allowed to stabilize for approximately five .'surs followed by 1 a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> Containment Integrated Leakage Rate Test. Shortly after the ILRT the supplemental test commenced to verify the accuracy of the Type A test. -
For a reduced pressure test, 0.75 L as determined during preoperational testing, is 0.13258 5t%/ day. The 1989 ILRT on Unit 2 containment yielded a least squares curve fit Lem of 0.0266 wt%/ day and a corresponding 95 percent upper confidence level L of 0.0272 wt%/ day. A valve lineup penalty _of .00969 6E%/ day.must be added to Ltm @ the 95% UCL (reference Appendix C)
- 2. 0 ' JESIGN INFORMATION 2.1 Containment Vessel Design The design parameters of the Unit 2 containment vessel have previously been described in references 6.1, 6.5, and 6.7.
2.2 ILRT Instrumentation System The Integrated Leakage Rate Test In'strumentation' System is designed to monitor containment parameters and calculate a leakage rate using the absolute method. Data read from the transducers is entered directly into a Hewlett Packard Model 1000 computer for reduction and analysis.
Details of the test system are described in reference 6.6. For this leakage rate test twenty-six resistance l
temperature detectors (RTD), eight humiters, three p.g precision pressure gauges and one flow meter were used.
l l 2.3~ ILRT Pressurization System The Containment was pressurized using Atlas Copco Corp.
L compressors, af ter coolers and air dryers connected to Prairie Island's pressurization line. All air released from containment for the leakage rate test was vented to the Auxiliary Building and hence monitored.by the Auxiliary Building ventilation radiation monitoring system. In addition, continuous air monitors (CAM) were positioned at the localized release path.
IBM L
ILRT Unit 2 Page 3 3.0 PRE-TEST CONSIDERATIONS 3.1 ILRT Instrumentation All instrumentation utilized during the ILRT was
{
calibrated by vendors whose Quality Assurance Programs !
were verified by Nor*hern States Power Company.
These instruments, all calibrated within six months of the test date, have calibration certification traceable to the National Bureau of Standards. Sensor calibration correction factors were then derived from the calibration curves.
Though not required by Technical Specifications, the containment fire detection system was temporarily modified by installing 12 photoelectric fire detectors in place of the existing ionization type. This was performed to avoid spurious fire alarms during periods when the containment was pressurized. No fire alarms were received during the duration of the test.
During the ILRT containment pressure was monitored by Control Room personnel via the containment wide range pressure channels. The six safeguards containment pressure channels were defeated by opening the test jack switches in the analog protection racks.
3.2 Venting and Draining Criteria The following criteria was used to determine the ILRT valve lineup:
- a. From 10CFR50 Appendix J:
(1) "Those portions of the fluid systems that are part of the reactor coolant pressure boundary and are open directly to the containment atmosphere under post-accident conditions and become an extension of the boundary of the containment shall be opened or vented to the containment atmosphere prior to and during the test."
(2) " Portions of closed systems inside containment that penetrate containment and rupture as a
. result of a loss of coolant accident shall be vented to the containment atmosphere."
(3) "All vented systems shall be drained of water or other fluids to the extent necessary to assure exposure of the system containment isolation valves to containment air test pressure and to assure they will be subjected to the post-accident differential pressure."
IBM
ILRT Unit 2 Page 4 (4) " Systems that are required to maintain the plant in a safe condition during the test shall be operable in their normal mode, and need not be vented."
(5) " Systems that are normally filled with water and operating under post-accident conditions, such as the containment heat removal system, need not be vented."
- b. Other Criteria:
(1) All isolation valves which shut automatically on a safeguards signal, which are shut manually as a part of the post-accident safeguards sequence, or which are normally shut during power operation (except venting lineups) shall be shut during the ILRT.
(2) Lines penetrating containment are to be vented to the outside atmosphere if, they are normally or potentially vented during power operation or if they could be vented after some phase of the safeguards sequence.
Normally closed systems outside of the .
containment shall also be vented unless they are Seismic Class 1.
- c. Pressure vessels inside containment vented to containment atmosphere during the ILRT:
(1) RCS via Pressurizer Vent (2) Reactor Coolant Drain Tank (3) Pressurizer Relief Tank (4) Power Operated Relief Valve Accumulators (2 trains)
(5) No. 21 & 22 SI Accumulators (6) No. 21 & 22 Steam Generator Snubber Accumulators r

- d. Electrical penetration venting ,
The electrical penetrations were. pressurized to 101 5 psig prior to the. ILRT. Any penetration i'.tdicating greater than 15 psig would require
.. investigation. During the ILRT, no electrical L penetrations were observed to be greater than 15 l .psig. The nitrogen supply to the electrical
, penetrations and the airlock electrical penetra-tions were isolated ,and vented to atmosphere.
- e. Water level in tbn following equipment is recorded before and after the ILRT:
(1) Reactor' Coolant Drain Tank (2) Pressurizer Relief Tank (3) Containment Sump A (4) Containment Sump B
'(5) 21 & 22 Steam Generator (6) Pressurizer 3.3 Local Leak Rate Testing Program The local leak rate test program was performed during each refueling outage as required by 10CFR50, Appendix J and Prairie Island Technical Specification 4.4.A. A summary of Type B and C test results, obtained since the last ILRT report was submitted, are in Appendices A, B, and C. The 1989 final results reflect the as-left conditions of containment after the 1989 Unit 2 Type A test. Local leak rate valve repairs are summarized in Appendix D.
The acceptance criteria for type B & C test are as follows:
- a. If the total leakage of all local leakage testing l exceeds 60% of L repairs and retests shall be performed to red 8c,e leakage below that value.
~
- b. Total leakage past isolation valves in systems in the Auxiliary Building Special Ventilation Zone (ABSVZ) shall be less than 0.1 wt%/ day at P,.
- c. Total leakage past isolation valves in systems exterior to both the ABSVZ and the Shield Building shall be less than 0.01 wt%/ day at P,.
IBM
ILRT Unit 2 Page 6-
- d. Airlock leakage shall be less than 1% of the L at 10 psig for the door innergasket tests and less than 5% of the L, at 46 psig for overall airlock tests.
344 C_ontainment Inspection
, A general inspection of the accessible interior and exterior surfaces of the containment and related components was performed prior to the ILRT as required
.. by 10CFR50, Appendix J, Section V. There was no evidence of structural d,egradation.
Additionally, the inspection revealed no pressurized containers, fire hazards or containment wall growth
-interferences. In general, the containment was very clean.
The annulus area was also inspected for wall growth interferences; none were found.

4.2 Type A Test and Verification Test Results and Conclusions J '
The Unit 2 Type A test and the Verification test were performed using the Mass Point Calculational Technique.
The Containment vessel was pressurized and allowed to
, stabilize for five hours. The Type A test then commenced.
The test data displayed acceptable results after only two hours of testing using the Mass Point Technique.
. The least squares leakage rate, L , at the final data point after 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of data collEEtion was 0.0266 wt%/ day with a correspon' ding L at the 95 percent upper confidence level equal to 0.02ff wt%/ day.
After the completion of the Type A test a supplemental test was performed to verify the validity of the Type A test measurements. A superimposed leak rate L = 1.2 L was initiated for the verification test. The fest was t per#ormed for four hours. The composite leakage rete exhibited very good correlation to the acceptance band: i 0.1945? wt%/d ay 1Le 1 0.28292 wt%/day Figure 1 through 8 display the results and parameters for the test period. Table 1 and Table 2 provide the applicable test data.
4.3 Ms 021-5 Evaluation As additional criteria the extended ANS 56.8 equations proposed by the U.S. Nuclear Regulatory Commission in Reg. Guide MS 021-5 were used during the Unit 2 ILRT.
This criteria defines three equations which must be satisfied prior to test end. Figures 9 and 10 entitled
" Extended ANSI Data Plots" represent these plotted values. Equation 1.1 represents a second order term as j computed from the least squares air mass regression l
.line. If a second order term is not present, equation 1.1 is satisfied and plotted above the 1.0 acceptance line. Equation 1.2 sets a limit on the relationship of the second order term's magnitude with respect to the allowable leakage rate of the containment under test. ;
Equation 1.2 is satisfied when ploted above the 1.0 j acceptance limit. Equation 2.1 represents the relation-ship between mass and time. This equation sets a limit on the allowed data scatter during the ILRT. The plotted equation 2.1 is satisfied when above the 1.0 acceptance limit.

ILRT 2 Unit 2 Page 8 Either equations 1.1 or 1.2.may be satisfied at any given time for valid test end. It is not necessary for these equations to be satisfied simultaneously.
Although, it is necessary for equation 2.1 to be satisfied simultaneously with either equation 1.1 or J. 1.2. As determined by this criteria both the Type A and Verification tests have a stable' linear regression with little data scatter. The results from MS 021-5 v add support to the 24 hcurs of Type A test data and 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> of Verification da,ta collected from Unit's April ILRT.
5.0 SPECIAL TESTING 5 .1- Shield Building Testing Section IV, ' paragraph B of 10CFR50, Appendix J, "Special Testing Requirements" and Technical Specification 4.4.A.6 require testing of multiple barrier containments. Unit 2 Shield Building is functionally tested at. quarterly intervals according to NSP Surveillance Procedure SP 2073. The Shield Building is functionally tested when each redundant train of the special ventilation system is tested to determine if it meets drawdown performance computed for the test condition with 75% of the Shield Building inleakage specified in Technical Specification Figure TS 4.4.1. None of~these quarterly tests on Unit 2 i Shield Building have failed to meet the acceptance L criteria due to Shield Building degradation.
5.2 Auxiliary Building Testing Technical Specification 4.4.A.6 requires retesting of the Auxiliary Building Special Ventilation Zone (ABSVZ).
Leak tightness of the ABSVZ is verified at quarterly intervals when each redundant train is run to determine if it can produce an acceptable negative pressure in the L zone within six minutes with an opening in the boundary of at least ten square feet. None of these quarterly tests have failed to meet the acceptance criteria.
