WESTINGHOUSE CLASS 3 PHASE 3 PASSIVE CONTAINMENT COOLING SYSTEM WATER DISTRIBUTION TEST 1.0 PURPOSE The purpose of the Passive containment Cooling System (PCS) is to remove heat from the post accident environment through the containment shell, The PCS accomplishes its purpose by means of evaporation of water delivered to the top of the steel containment structure. The evaporation occurs as the water flows over the containment dome and sidewalls.

The PCS achieves maximum effectiveness when the cooling water is uniformly distributed so that maximum containment area is wetted.

The purpose of the Phase 3 Passive Containment Cooling System (PCS) Water Distribution Test is to provide a large-scale demonstration of the ability of the finalized weir design to distribute water on the outer surface of the steel containment dome and the top of the sidewall as part of the PCS function.

2.0 OBJECTIVES The objectives of the Phase 3 Passive containment Cooling System Water Distribution Test are to assess the effectiveness of the weir design to distribute water over the containment dome and top of the sidewall for the entire range of expected water flow rates and to provide a large scale visual demonstration of the water distribution over the containment dome.

The specific objectives of the test are:

Determine the flow off the sides and bottom of the model with weirs over the range of expected flow rates, Determine film thickness and volumetric flow rate at the springline of the model to adequately characterize the thin film flow for use in safety analysis.

4.0 TEST FACILITY REQUIREMENTS The Phase 3 test shall be performed on the existing Phase 2, 1/8th segment model located at Waltz Mill.

A description of the existing facility is found in References 1 and 2.

4.1 MODIFICATIONS TO THE TEST FACILITY Following completion of Test 8 (as described in Section 8.0, Test Operation and Data Requirements), a 5-foot collection gutter shall be attached to the Page 1 of 5 1

i

\\

l existing model. The gutter shall be placed approximately 3 feet from the bottom of the model and be positioned such that it does not cross a simulated weld.

The position of the gutter shall be recorded.

The gutter shall be attached to the model such that no water shall pass under the gutter.

The gutter shall be divided into 3 inch collection troughs for the purpose of obtaining a volumetric flow rate of water on the model.

Each collection trough shall be equipped such that the water collected in the trough may be directed to a lower collection trough, a drain, or a graduated measuring device.

Following completion of test 14, simulated baffle support plates shall be attached to the model. The design and location of the support plates shall be provided later.

5.0 TEST ARTICLES The test articles shall consist of the weirs to be attached on the model surface. These test articles shall include:

The V-notch weir design (to be provided under a separate letter) shall be attached to the model surface.

The cognizant test engineer shall note, document, and evaluate local surface imperfections for acceptability following attachment of a weir.

In general, any surface imperfection resulting from attachment of the weirs shall not dominate the resulting flow distribution.

6.0 INSTRUMENTATION REQUIREMENTS The instrumentation for Phase 3 of the test shall be sufficient to provide the following data:

Measurement of the film thickness over the surface of the simulated containment dome section in each flow stream across the springline.

Measurement of the water which leaven the periphery of the model.

Measurement of the water which leavrs the model surface through the collection cups.

Measurement of initial water temperature

(+/- l'F)

Measurement of total water flow rate delivered to the test article

(+/- 2%).

Measurement of total time of each test.

7.0 DATA ACQUISITION AND PRESENTATION Test data shall include documentation of the weir positions.

In addition, data sheets shall be prepared for each test run.

Water temperature and total flow measurements shall be taken for each test and included on the data sheet.

Tests shall be divided into two series. The first series (tests 1 through 8) shall be used to determine the flow distribution on the model by recording the collection drum measurements. All tests shall be recorded on video. The second series of_ tests thickness at the(

(tests 9 g(a, rough 14)

Q shall be used to determine film m

j pproximately 6-inches above the upper collection gutter) and the springline (approximately 4 feet off floor), as well as volumetric flow rate at the spr:pgline. The filg thickness shall be 3*#Mh11 only be taken measured in each flow stream across the dnd the springline.

Note that the measurements taken at the[

across half of the model, above the upper collection gutter. The volumetric flow rate at the springline shall be taken by collecting water in the additional collection gutter and measuring the rate of water collection.

8.0 TEST OPERATION AND DATA REQUIREMENTS The proposed test matrix is provided in Table 8-1.

Several runs may be eliminated or modified during testing.

- 3,C, 9.0 TEST REPORTS AND DATA RETENTION A construction plan / facility description detailing model construction methods has been submitted and is documented Reference 2.

Additional information is provided in Reference 1.

A Test Operating Procedure shall be prepared in accordance with the applicable QA requirements of Section 10.0 and shall be submitted to the author of this j

specification for review and approval prior to the start of testing.

Separate procedures shall be prepared for measuring film thicknesses and volumetric flow rates and shall be submitted to the author of this specification for review and approval prior to the start of testing.

Data from the tests shall be provided following testing. Data shall include either the flow distribution to the collection buckets or film i

thickness / volumetric flowrate measurements. A video tape of each test shall be provided.

10.

QUALITY ASSURANCE REQUIREMENTS Testing quality assurance shall conform to ANSI /ASME NQA-1-1986.

As this is a safety related test, the Code of Federal Regulations, Title 10, Part 21, (10CFR21) is also applicable. To incorporate the requirements of NQA-1, the Page 3 of 5

following measures shall be taken in the detailed test procedure:

1)

Provisions for ensuring that those performing the tests are qualified and trained in the quality assurance requirements of the specification.

2)

Provisions for ensuring that changes to the test procedure are reviewed and approved to the same extent as the originals.

3)

Provisions for ensuring that the latest approved revision of the test procedure is used.

4)

Provision for calibration of test equipment, traceable to recognized national standards.

If no such standard exists, a description of the calibration method shall be included.

5)

Provisions for verification and configuration control of computer software (if any) used to collect or reduce data.

6)

Provision for reporting and reconciling deviations from the approved test procedure.

l 7)

Provisions (such as a signed checklist) for ensuring that test l

prerequisites are met.

Test prerequisites include calibrated instrumentation, appropriate equipment, trained personnel, condition of l

test equipment and item (s) to be tested, suitable environmental

[

conditions, and provisions for data acquisition.

8)

Provisions for ensuring that necessary monitoring is performed and that test conditions are maintained.

(A test log containing periodic signed entries that include any pertinent observations or information not captured elsewhere is recommended.)

9)

Documented evaluation of test results by the test sponsor to ensure that test requirements were met.

10)

Identification in the test records of items tested, date of test, instrumentation and data recorders, type of observation, results and acceptability, action taken in connection with noted deviations, and person who evaluated the test results.

11)

The testing organization shall verify and document that the instrumentation calibrations have been performed prior to testing. This j

documentation must be submitted to the test sponsor.
