I. INTRODUCTION A periodic Type "A" Integrated Leak Rate Test (ILRT) was performed on the containment structure of the Toledo Edison Company's Davis-Besse Nuclear Power Station (DBNPS) pres-surized water reactor in October of 1991. The results of this test were anelyzed utilizing the " Total-Time" methr: ,
This test was performed for a period of 6'.2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> at a p res-sure equal to or greater than the calculated peak contain-ment internal pressure related to the design bases cccident and specified in'the Technical-Specifi ations. This report describes and presents the results of this periodic Type A test including the supplemental test method utilized for verification (Controlled Leak Rate Test or CLRT).

The test results are reported in accordance with the re-quirements of 10 CFR 50, Appendix J, Section V.B.2.,
ANSI N45.4-1972 and the intent of ANSI /ANS-56.8-1987.
In addition, Type "B" and "C" test results performed since the last Type "A"-test are included in this report (Appen-dix B) in accordance with the requirements-of 10 CFR 50, Appendix J, Section V.B.3.

SUMMARY
Prior to performance of the ILRT, Local Leak Rate Tests (LLRTs), were performed to verify containment integrity.
These Type "B" and Type "C" tests were performed on contain-ment electrical penetrations, mechanical penetrations, con-tainment isolation valves, fuel transfer tubes, equipment hatch, and air locks. The acceptance criteria for the LLRTs is that the total leakage does not exceed 0.60 (L,) where L, is the maximum allowable leakage rat at pressure P, (peak accident pressure) stated as a percent of containment free volume per day (24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />). The total leakage from these tests was well within this limit, and the results are pre-sented in the ofricial copies of the associated Type B and C surveillance test procedures, DD-PF-03000 (Containment ves-sel Local Leakage Rate Test), which are on file at the DBNPS.
At the start of the ILRT, all valves were in their normal position for accident conditions. Exceptions to this valve line-up were identified in the official copy of acceptance test procedure DB-PF-10309 (Containment Integrated Leakage Rate Test), w'ich is also on file at the DBNPS.

(Continued)
The first order least-squares fit analysis of the data uti-lizing the Total-Time method yielded a leak rate of 0.022770% per day with a 95% upper confidence limit of 0.061169% per day. These values are well within che allowable limit of 0.375% per day.

C/ A. Description of Containment The containment for the station consists of three basic structurest a steel Containment Vessel, a reinforced concrete Shield Building, and the internal structures.
The Containnent vessel is a cylindrical steel pressure vessel with hemispherical dome and ellipsoidal bottom which houses the reactor vessel, reactor coolant pip-ing, pressuriser, pressuriser quench tank and coolers, reactor coolant pumps, steam generators, core flooding tanks, letdown coolers, and normal ventilating systems.
It is completely enclosed by a reinforced concrete a
Shie? auilding having a cylindrical shape with a shal-
. .g low dome roof. An annular space is provided between l
the wall of the Containment vessel and the shield Building. There are no structural ties between the containment Vessel and the Shield Building above the foundation slab. Above this, there is unlimited free-dom of differential movement between the Containment vessel and the Shield Building. The containment inter-nal structures are constructed of reinforced concrete and structural steel. These structures are isolated from the Containment' Vessel by steel grating panels with sliding supports which allow free differential e

The non-field stress relieved Containment vessel was constructed in a two-stage operation and in a manner that conforms to the ASME Boiler and Pressure Vessel Code, Article 14, N-1411. The vessel inside dianieter is 130 feet and the net free volume is approximately 2,834,000 ft3 The cylindrical shell and bottom head thickness, exclusive of reinforced areas, is 1-1/2" s
with a dome thickness of 13/16". The 180-ton polar x s-crane is supported from the cylindrical vessel shell by a 14' 6-1/2" deep by 5' 11" wide circular crane girder.
Access to the containment is provided by an equipment hatch, a personnel air lock, and an emergency air lock.
Electrical and mechanical penetrations are provided for services to the containment.
The Containment vessel is capable of withstanding an external pressure differential of-0.50 psi in accor-dance with the ASME Boiler and Pressure Vessel Code,Section VIII, UG-28. The Containment Vessel is vented as required to eliminate pressure fluctuatione caused D
y A. Description of Containment (Continued) by air temperature changes during various operating modes. This is accomplished through ventilation purge connections which are normally closed while the reactor is in operation. Automatic vacuum relief devices are also used to prevent the Containment Vessel from ex-ceeding the external design pressure in accordance with the requirements of the AsME Boiler and Pressure Vessel Code,Section III, Article 16. Multiple vacuum breek-ers are used to relieve pressure from the Shield Build-ing into the containment in case the containment vessel is subjected to excess external pressur6. These 'ralves ensure that external pressure differential on the Con-O i tainment vessel does not exce.d 0.50 psi.
The reinforced concrete Shield Building was designed in accordance with ACI 307-69, Specification for the Design and Construction of Reinforced Concrete Chim-neys, and checked by the Ultimate Strength Design '
Method in accordance with ACI 318-63. Load combina-tions specified in ACI 307-69 provide the design basis of the Shield Building. The Shield Building is designed to provide biological shielding during normal operation and from hypothetical accident conditions.
The building provides a means for collection and fil-tration of fission product leakage from the containment O

Vessel following a hypothetical accident through the Emergency Ventilation Syetem, an engineered safety feature designed for that purpose. In addition, the building provides environmental protection for the Containment Vessel from adverse atmospheric conditions and external missiles. The Shield Building annulus volume is 670,700 ft'. The Emergency Ventilation Sys-tem limits the temperature induced pressure transients in the annular space to 6 inches H,0 during a loss of coolant accident (LOCA). Following the initial pres-sure transient, the annulus pressure is maintained
-between (-)l/4-and (-)l-1/2 inches water gauge.
The Containment vessel is designed for the following temperature and pressure conditions:
- Maximum Internal Pressure - 40 psig
- Design Internal Pressure - 36 psig, 264*r maximum Leakage Rate Test Pressure - 38 psig
- Negative Pressure - 0.5 psig
- Service Metal Temperature - 30*r Maximum Operating Ambient Temperature - 120'r

B. Description of Instrumentation A " state-of-the-brt" ILRT instrumentation system was utilized to allow leak rate determination by the "Abso-lute Method". The primary measurement variables in-clude containment pressure, relative humidity (dewpoint temperature), and dty-bulb temperature as a function of me. The Data Acquisition System or DAS utilized was a Fluke todel 2286. Two DAS devices were utilized with one as a primary while the second was available as a backup, Ancillary measurements include outside ambient temperature and barometric pressure. During the supplemental CLRT, containment verification ( f i x e d--
orifice) flow is also measured. Instrument readings were acquired at 15-minute intervals vi4 a data acqui-sirion system. The measurement system schematic is t ,

C. Description of Computer Program
(
The computer program utilized for the performance of the Davis-Besse ILRT is written entirely in C_ language.
It is an interactive system that utilizes the Microsoft Windows operating environment. Windows provides a "shell" that allows programs to run within a window-based' user environment and provides sufficient multi-tasking utilizing the latest PC software.
Windows allows multiple programs to operate simultane-ously and communicate with each other. This allows the Data Acquisition System (DAS) program to communicate with the ILRT analysis program by passing data in t memory and providing a " device independent" way to interface with output devices. Windows includes an intuitive user interface _through the use of pull-down menus and provides multiple views of data simultaneous-ly thus allowing real-time updating of displays. All calculations can be performed automatically and-all-graphs and displays can be updated immediately on the screen upon receipt of new data.
The ILRT program consists of two (2) separate programs.
The main program called LEAK.EXE is a data _ analysis and reporting program. Its " personality" is derived from:a
l C. Description of Computer Program (Continued) configuration file. The ILRT program contains the tools-required to create and edit the configuration file. The second program called DATnwQ.EXE controls and provides interface to the DAS. The main program communicates with the DAS internally through a Windows facility called Dynamic Data Exchange (DDE), allowing a standardized vay of communicating while' keeping the main program isolated from the actual details of data acquisition. The configuration file specifies all plant-specific information such as number of compart-ments or zones in containment, number of each type of sensor each compartment contains, individual sensor
( calibration constants, volume fractions, containment volume, etc. All configuration information is acces-sible within the program and easily accessed through standard Windows dialog boxes.
Prior to actual test performance, the program allows loop checkout and troubleshooting of data' acquisition all the way from the sensor proper to the computer.
This validates the configuration file and performs a consistency check. The confinuration file validation is automatically performed upon-initiation of data acquisition. Once pressurization begins, the Pressuri-zation Monitor allows monitoring of pressurization s-

} C. Description of Computer Program (Continued) trends until test pressure is achieved. At this point, the Temperature Stabilization window is utilized and determines when stabilization is achieved. This func-tion is formatted exactly like Appendix r of ANSI /ANS-56.8-1987. Once temperature stabilization is
-achieved, the ILRT start reading or sample number is selected and all leak rate calculations are performed up to the current reading. As subsequent data sets arrive, leak rate calculations are updated automati-cally. The leakage calculations are performed utiliz-ing both Total-Time ar.3 Mass-Point methodologies with Total-Time calculations performed in accordance with
( BN-TOP-1. Edit provisions exist within this program for failed sensors, corresponding volume fraction re-distribution, invalid data sets, etc. All calculations are updated automatically to reflect any changes of this type that are made. In conjunction with this, a continuous calculation of the Instrument Selection L
Guide (ISG) is performed during the test based upon test duration and number of sensors. This assures the ISG requirement is being met if. test duration is re-duced and/or unacceptable sensors are eliminated. Upon successful completion of the ILRT, the program calcu-lates a knownl leak in SCFM equal to L, for the CLRT.
l l
The actual leak that was imposed is manually entered x
s C. Description of Computer Program (Continued) and the program calculates the acceptance band for the verification test based upon this value. When all testing is complete and depressurization begins, the Depressurization Monitor allows monitoring of depre-ssurization trends until atmospheric pressure is achieved. Extensive reporting and graphical options exist within the program and are available in hard copy by utilizing the Print option.
Test parameters measured are pressure, dewpoint temper-ature, and dry-bulb temperature inside the containment.
,_s Instrument readings taken by the DAS are recorded on I the hard disk of the computer and from these data, the s
leak rate is calculated. All data, both raw and calcu-lated, can be displayed on the computer monitor. Use of the absolute pretsure method as described in ANS N45.4-1972 is the basis for the leakage calcula-tions performed by the ILRT system program. The methodologies utilized are the Total-Time analysis as described in BN-TOP-1 and the Mass-Point analysis as described in ANSI /ANS-56.8-1987.

Prior to this, various tasks were completed such as instrument sensor instal-lation, in-situ testing, temperature survey, Type B and C testing, valve line-ups, etc. Various minor problems were encountered and resolved during this period. The details concerning these issues can be found in accept-ance test procedure DB-PF-10309, containment Integrated Leakage Rate Test, and the associated test log which are-on file at the DBNPS. l Pressurization of containment commenced at 1800 hour0.0208 days <br />0.5 hours <br />0.00298 weeks <br />6.849e-4 months <br />s- ;

The average pressurization rate was approximately 2.5 psi / hour. Upon reaching P,, pressure was. decreasing more than anticipated.- This was attributed to-the fact that-containment. average-ambient temperature prior to close-out was approximately 67'F, As arresult, containment average temperature at P, was-being " dragged down" with a corresponding effect on pressure. .Thl= created a concern of being at less than P, prior to actual commencement of the ILRT. To avoid this condition, repressurization recommenced at 1215-

Following satisfactory completion of the ILRT at p. , a 4.2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> CLRT was performed with a total of 21 samples or data sets taken. This test was conducted by superimposing a known fixed-orifice leak approximately equivalent to La (0.5% per day) of 35.9 scfm. The calculated Total-Time leak rate for CLRT was 0.579865% por day.
Following valve repairs during the refueling outage, the total Type D and C minimum pathway leakage improvement was 0.00145% per day. Added to the "As-Left" results value above, this yielded an "As-Found" Type A test result of 0.063629% per day.
! V. CONCLUSIONS The Integrated Leak Rate Test at peak accident pressure provided acceptable results as evidenced by the computer printouts in Appendix A of this report. The computed leak rate is well within the specified limit. The acceptance criteria for the ILRT is as follows:
- 1. The maximum allowable operational leak rate shall not -
exceed 75% of L, (0.5% per day) at a pressure of not lees than P, (38.0 psig):
- 0.375% per day
- 2. The accuracy of the ILRT is verified by a supplemen-tal test (CLRT) where a calibrated leak is imposed on the existing leaks (L,,) in the containment system.
The superimposed leak rate (Lo) shall be between 75% .
and 125% of L,.

- 1. The Trend Report based on Total Time calculations shall indicate that the magnitude of the calculated leak rate is tending to stabilire at a value less than the maximum allowable leak rate (<.75La).
Required Value: 0.375000 %/ day Actual Value: 0.022770 %/ day (Note: The magnitude of the calculated leak rate may be increasing slightly as it tends to stabilire. In this case the average rate of increase of the calculated leak rate shall be determined from the accumulated data over the last five hours or list twenty data points, whichever provides the most points, t : sing this average rate the calculated leak rate can then be .nearly extrapolated to u o 24th hout data point.
If this extrapolated value of the calculated leak rate exceeds 75% of the maximum allowabl6 leak rate (La) then the leak rate test is continued.)
Required Value: 0.375000 %/ day Actual Value: 0.000000 %/ day f

) 2. The end of test upper 95% confidence limit for the calculated leak rate based nn Tota) Time calculations shall be less than the maximum allowable leak rate (<.75La).
Required Value: 0.375000 %/ day Actual Value: 0.061169 %/ day
- 3. The mean of the measured leak sates based on Total Tirm calculations over the last five hours of test or last twenty data points, whichever provioes the most data, shall be less than the maximum allowable leak rate (<.75La).
Required Value: 0.375000 %/ day Actual Value: 0.045863 %/ day
, 4. Data shall be recorded at approximately equalintervals and in no case at intervals greater than one hour.
Required interval: < = 1 hr Maximum ActualInterval: 0.25 hr

Introduction Appendix B summarizes the results of the Local Leak Bate Test (LLRT) data which was obtained from periodic testing I
performed since the September 1908 periodic Type A test.
Data is provided for surveillance testing performed in 1990 t
and 1991. The leakage rates that are listed in Appendix B i are individua? valve measurements unless otherwise noted.
The acceptance criteria for Types B and C testing is in accordance with 10CFR50, Appendix J. The combined leakage a d e for all penetrations and valves subject to Types B and C tests in 1990/1991 were well below the acceptance criteria ,
of less than 0.60L ' .
