SECTION 2 SLMfARY 2.1 TYPE A TEST 2.1.1 TYPE A TEST SLHMARY A plot of the mass versus time for the period of 1022 hours0.0118 days 0.284 hours 0.00169 weeks 3.88871e-4 months on April 5, 1985 to 0900 hours0.0104 days 0.25 hours 0.00149 weeks 3.4245e-4 months on April 6, 1985 is shown in Attachment 2.1.

This period coincides with the end of temperature stabilization to just af ter the last adjustment to the containment boundary.

Typically, significant changes in the mass trend can be achieved by isolating significant leakage paths.

Using graphical techniques, these changes or breakpoints, can usually be seen immediately although several data points, e.g. two hours minimum, are required before an analytical analysis can be predicted with certainty. This breakpoint analysis will be caed to evaluate each action that was performed during the leakage investigation period.

The temperature stabilization criteria of 1-PT-57.1, Revision 1,

was satisfied at 1010 hours0.0117 days 0.281 hours 0.00167 weeks 3.84305e-4 months on April 5, 1985. The mass trend data from 1022 hours0.0118 days 0.284 hours 0.00169 weeks 3.88871e-4 months on April 5, 1985 to 0326 hours0.00377 days 0.0906 hours 5.390212e-4 weeks 1.24043e-4 months on April 6,

1985, shows an excessive mass loss of about 39 lba per hour.

This race exceeded the procedure's acceptance criteria of 0.75 La, or 0.195 percent / day, test which is approximately 13 lbm per hour.

In order to reduce the mass loss, or to place the containment boundary in its most conservative configuration, the following actions were performed:

a)

At 1700 hours0.0197 days 0.472 hours 0.00281 weeks 6.4685e-4 months on April 5, 1995, the Residual Heat Removal System (RHS) root valve IRH3*V15 was closed to stop the loss of suppression pool wa:er.

The local leakage was approximately 0.625 gallons per minute.

b)

At 2130 hours0.0247 days 0.592 hours 0.00352 weeks 8.10465e-4 months on April 5, 1985, the Main Steam Isolation Valve (MSIV) Outboard division was pressurized to slightly less than containment pressure.

c)

At 0315 hours0.00365 days 0.0875 hours 5.208333e-4 weeks 1.198575e-4 months on April 6,1985, the Reactor Plant Ventilation (HVR)

System differential pressure transmitter low side isolation valves were closed.

d)

At 0823 hours0.00953 days 0.229 hours 0.00136 weeks 3.131515e-4 months on April 6, 1985, the motor operated valve IDFR*MOV146 was opened.

2-1

Each of these actions is evaluated separately, using the breakpoint technique to determine whether the leakage path was significant.

The following Table summarized the mass trend data before and after the action.

If the before and af ter mass trend data is the same, the action is judged to be insignificant. Also, reference Attachment 2.1.

Based on the results of Table 2.1 the only action that is judged to be significant is the isolation of the HVR instrument isolation valves at 0315 hours0.00365 days 0.0875 hours 5.208333e-4 weeks 1.198575e-4 months on April 6, 1985.

1RHS*V15 is an instrument root valve on the discharge of 1RHS*PC0025.

It was to be closed during the Type A test as Operations had been using a temporary connection on one of the downstream instruments to vent the RHS pump casing. This root valve would normally be open, and the system subject to periodic inspection for system leakage during plant operation.

Adequate administrative controls exist regarding the alignment of systems, the tagging of system components, and the handling of temporary system modifications.

The mispositioning of 1RHS*V15 is a procedural and a tagging concern, not a Type A concern.

2-2

i The MSIV lines are excluded fros the Type A Leakage per River Bend Final Safety Analysis Report (FSAR),

Section 15.6.5.5.2 Fission Product Transport to the Environment.

During the Type A test, these lines were pressurized to less than Pa to minimise the outleakage.

The original airblock consisted of pressurising only the body of the outboard division block valve.

As the line from the outboard MSIV to the block valve is a large disseter line, it was pressurized to reduce any leakage by the inboard division. The leakage of the MSIV divisions are treated as Technical Specification surveillance tests. The low leakage reported by the surveillance tests combined with the insignificant change in the mass trend, indicates that the pressurizing of the outboard division was not a significant leakage path.

The HVR differential pressure transmitters were the significant leakage path. There are six HVR differential pressure transmitters that monitor the annulus and containment differential pressure for automatic shutdown of the containment unit coolers to aid in preventing containment negative pressure.

The isolation provisions for these lines are discussed in the River Bend FSAR, Section 6.2.4.3.5 Conformance to Regulatory Guide 1.11.

Three of the six HVR differential pressure transmitters were not properly aligned for the Type A test.

Only the positions of the root valve were specified.

See Section 2.1.2 for the recommended corrective action.

The 1DFR*MOV146 had been installed just prior to the Type A test.

Control and power cables had not been run, nor had the generic electrical testing been performed.

The position of all containment isolation valves were set prior to the performance of the Containment

(

Wald Integrity Test.

This valve was supposed to be opened but its opening was restricted by a tagging clearance.

Since it had not been closed by its nor=al means, it was conservatively opened.

The downstream check valves had been air seat leakage tested prior to the Type A.

The Type C test combined with the relatively insignificant change in the mass trend, see Table 2.1, indicates that the DFR actor operated valve position change did not significantly impact the leakage trend.

2.1.2 Corrective Action The leakage investigation resulted in a number of actions taken to reduce the leakage trend.

Each action taken was properly documented prior to performing the action.

The effect of each action was monitired using the Type A mass trend to determine which leakage path was significant.

This analysis has identified the three HVR differential pressure transmitters as the sole leakage paths responsible for the excessive leakage race.

These paths were not the result of a failed component, nor the result of an unconservative local leakage test.

The Type A Procedure failed to adequately address the entire valve alignment required for these transmitters.

To prevent the occurrence of the HVR leakage again the following corrective action is to be taken:

a)

The surveillance Type A procedure will address the entire valve alignment for all of the instruments included in the River Bend FSAR, Section 6.2.4.3.5.

b)

Permanent caution tags will be placed on the instrument valves (equalizing, vent or drain valves, and test valves) stating that the valve is a containment isolation valve and that it is to be normally closed except when performing asintenance or calibration.

c)

The instruments will have the position verified every 31 days per the recommendations in the Standard Technical Specifications Section 3./4.6.1.1 (b).

In addition to the HVR corrective action, all changes made to the preoperational Type A test procedure will be evaluated for incorporation into the surveillance Type A procedure.

2.1.3 Conclusions The preoperational Type A test should be considered a successful test as ence the HVR procedure deficiency was corrected the measured leakage rate was well within the plant's maximum allowable leakage rate.

The preoperational Type A test was run for a minimum of twenty-four (24) hours in order to verify that there were no effects due to diurnal bias, based on the data taken.

2.2 LOCAL LEAKACE RATE TESTS (TYPES B AND C)

The Local Leakage Rate Tests (LLRT's) of containment isolation valves and other primary containment penetrations were performed by the methods described in the plant preoperational test procedure No. 1-PT-57-2, and 1-PT-57-4.

in accordance with Appendix J to 10CFR50, Paragraph V.B., data for the Local Leakage Race Tests are summarized in Section 4 of this report.

Only the LLRT's for those containment isolation valves that are in the Appendix J.

10CTR50, Type B and C program are included in Section 4 of this report. LLRT's for valves that are a part of the Technical Specification Program (e.g. bypass or penetration leakage collection systems) have been exempted from the Appendix J.

10CFR50 Program.

The LLRT's for these exempted valves are maintained in the site test records.

3.2-1

i.

1 3.2.2 Equipment Pressurization of the containment was achieved by the utilization of a temporary system consisting of diesel driven air compressors, an aftercooler, and a refrigerant air dryer sa shown on Attachment 3.20.

Adequate instrumentation and valving were installed to maintain the quality of the air throushout the pressurization sequence.

3.2.3 Instrumentation The various containment and drywell parameters required to calculate the leakage rate during the ILRT were monitored using pressure, temperature and moisture sensors.

Pertinent data for the temporary ILRT instrumentation is listed in Attachment 3.2A.

The temperature zone layout is shown on Attachment 3.25.

The following table describes the arrangement of the moisture zoness Temperature Zones Zone A I and II Zone B III through VI Zone C VI and VIII A rotameter was used to perform the superimposed leakage verification test.

With the exception of this rotameter, all test instrumentation was monitored by the plant computer.

3.2-2

3.2.4 Data Aquisition System The data acquisition system used for the River Band tl nit No.1 ILRT was the Emergency Response Information Systes (ERIS) Computer.

For the ILRT, ERIS monitored the following parameters:

Containment Dryvell Temperatures 18 4

Moisture 4

2 Pressure 1

1 The input to the ILRT programe was an ERIS calculated ten minute average.

Each data set was time stamped to account for any time skewing.

Instantaneous data (e.g. one sampling for each sensor) was also taken every ten minutes during the test period.

The ILRT program performed sensor validity checks on the temperature, noisture, and pressure sensors to identify any aberrant behavior.

There were no sensor failures during the April 1985 ILRT.

3.2.5 Data Resolution System The ERIS ILRT Computer program calculated the leakage rate using the Absolute Method, Mass Point Analysis.

The leakage rate was also calculated using the Absolute Method, Total Time Analysis.

The Total Time Analysis was run on the Stone & Webster Engineering Corporation's portable computer.

Absolute Method. Mass Point Analysis The Absolute Method, Mass Point Analysis consists of calculating air masses within containment structure, over the test period, from pressure, temperature, and dowpoint observation s made during the ILRT.

The air masses are computed using the ideal gas law as follows:

M = 144V (P-Pv)

(Eq. 1)

RT I

Where M = air mass, iba P = total pressure, psia Pv=averagevaporpresgure, psia R = 53.35 Pt - lbf/1ba R (for air)

T=averagecontainmenttemperajure,'R V = containment free volume. Ft I

i l

3.2-3

r The leakage rate is then determined by plotting the air mass as a function of time, using a leset-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 0.00667 hours 3.968254e-5 weeks 9.132e-6 months or symbolically:

Leakage rate = A/S (-2400)

(Eq. 2)

Where A is the slope of the least-squares curve and 5 is the y-intercept.

The sign convention is such that an outward leak is positive and the units are in percent / day.

In

general, the containment is divided into two volumes the containment and the drywell air volumes.

The mass of each volume is computed separately and added together.

The result is correlated as a function of time by means of a least-squares curve fit of the forms M = At +5 (Eq. 3)

The slope A and the y-intercept 5 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 sua of the leakage rate and the 95 percent confidence interval is the upper confidence limit (UCL). The measured leakage rate may be described as 95 percent accurate to within the value of the UCL.

Absolute Method. Total Time Analysis This method consists of calculating a measured leakage rate.

The containment air mass is computed using Equation 1.

The measured leakage rate at any time (c) is then determined by subtracting the mass at the time (H ) from the initial mass (H ) and then by dividing by the initial, g

g mass.

The measured leakage rate is then expressed as a percentage of the containment mass lost in 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months or symbolically:

Measured leakage rate = Mi - Me (2400)

(Eq. 4)

Mi (at)

The sign convention is such that an outward leakage rate is positive and the units are in percent / day.

The estimated leakage rate is then determined by performing a linear least squares fit of the seasured leakage rate values, as follows:

Estimated leakage rata = At+5 (Eq. 5)

Where A is the slope and 5 is the y-intercept of the least squares line.

The confidence level is determined in accordance with the equations of SN-70F-1, Revision 1 Testing Criteria for Integrated Leakage Rate Testing of Primary Containment Structures for Nuclear Power Plants.

The sua of the total time estimated leakage rate and the confidence limit is the Upper Confidence Limit (UCL).

3.3 TEST RESULTS 3.3.1 Presentation of Test Results The test data for the April 1985 ILRT is based upon a 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months test period starting at 0326 hours0.00377 days 0.0906 hours 5.390212e-4 weeks 1.24043e-4 months on April 6, 1985 to 0328 on April 7, 1985.

The final test results were determined using CSU's ERIS Computer for the i

Mass Point Analysis, see Attachment 3.35, and by SWEC's portable computer for the Total Time Analysis, See Attachment 3.3C.

Both the Mass Point and the Total Time results were well within the 0.75

(

L,, or 0.195 percent / day.

The Type A test results were verified by performing a superimposed leakage rate test.

Both the Mass Point and Total Time test results for the superimposed leakage test were well within the Appendix J.10CFR50 acceptance criteria of + 0.25L,

or + 0.065 percent / day.

The information for the superimposed le$kage test is contained in Attachment i

3.30.

3.3.2 ILRT Results The ILRT was conducted in accordance with the River Bend ILRT test procedure 1-PT-57-1, Revision 1.

SECTION 4 LOCAL LEAKACE RATE TESTS (TYPES B AND C) A summarizes the Local Leakage Rate Tests (LLRT's) data that was established to support the overall containment leakage testing program. B summarized 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.

The LLRT's were performed by pressurizing the listed penetrations with air or nitrogen and either measuring leakage across the containment isolation valves (Type C) or across the resilient seals (Type B).

Each penetrations leakage rate can be obtained from site reference material. C susssarizes the results of the hydrostatic local leakage tests conducted on valves, identified in the plant Technical Specification, as being in systems that remmi'.s either filled or sealed by water.

The acceptance criteris of Types B and C testing is in accordance with 10CFR50, Appendix J.

The combined leakage rate for all penetrations and valves, subject to Types B and C tests, is well below the acceptable leakage rate of 0.6L,.

The Attachments for this section are:

LOCAL LEAKAGE RATE TEST DATA.

NOTES:

l.

The preliminary local leakage rate program commsenced approximately 12 months prior to the Type A test.

Repairs performed to these isolation valves were generally minor in nature and consisted of packing adjustments, torque switch adjustments, lapping, cleaning / flushing, and alignment adjustments.

Specific repairs are identified in the site maintenance records. Containment i

isolation valves that are not Type C tested, but that are tested in a separate Technical Specification Program (e.g. bypass leakage, seal system, etc.) are not included in this Report.

2.

Valves IDFR*V181, IDFR*V182, and IDFR*MOV146 are part of a

recent modification.

The Type C seat leakages will be reported under the Technical-Specification Surveillance Program.

The seat leakage test will be done prior to Primary Containment Integrity - Operating being require'd.

L 3.

Valve ISSR*SOV139 was not Type C leak tested prior to the Type A test.

The Type C seat leakage will be reported under the Technical Specification Surveillance Program.

The seat leakage test will be done prior to Primary Containment Integrity - Operating being required.

19 penetration assembly 4.

These are penetration assembly bellows.

There are bellows.
