.' l.0 INTRODUCTION .

This document describes testing conducted for Commonwealt!' Edison Company,

Zion Station to evaluate the effects of paint ch;ps on sump strainer screen head loss.

Testing was conducted at the laboratory facilities of Continuum Dynamics, Inc. In Princeton, New Jersey following the test plan described in Reference 1. The primary objective of the program was to determine the head loss across the strainer sump screen

-as a result of the buildup of paint chips. Paint chips of different sizes and thicknesses-were tested. All tests were conducted with chips made from Ameron/Amercoat 90HS high performance epoxy paint. De test apparatus consisted of a simulated portion of the full scale Zion Station strainer sump screen mounted in a 675 gallon,82 inch diameter - 1 tank. Prototypical, full scale strainer screen approach velocities were maintained for all of the tests.

The tests documented in this report were observed by Commonwealth Edison

. personnel on July 9,1997 at the Continuum Dynamics, Inc, laboratory facilities. A series of tests were conducted in March 1997 under similar conditions with essentially the same results but the tests were not witnessed by Commonwealth Edison perosnnel (Reference 2), ne March 1997 tests were documented in C.D.I. Technical Memorandum No. 97 05,  ;

April 1997.

l 2.0 TEST FACILITY APPARATUS 2.1 Strainer Model The test apparatus is sh..n schematically in Figure 21. One corner of the full scale Zion Station sump strainer was modeled using nominal 1/2 inch mesh,14 gage,304 SS wire cloth supplied by Commonwealth Edison The cloth was painted with Keeler &

Long E-17475 Epoxy Enamel paint. The strainer was constructed with two approrimately 6.25 inch deep by 12 inch high sides with a 3 inch by 3 inch angle added at the intersection of the two sides to model a support angle. The total surface area of the strainer was 1.05 square feet. To better visualize the testing, the remainder of the structure (remaining sections of sides and the top) were fabricated from 1/2 inch thick clear polyca'rbonate sheet. A photograph of the modelis shown in Figure 2.2 The model was mounted to the floor of a 675 gallon tank with a diameter of approximately 82 inches and a height of 30 inches. To simulate prototypical now conditions through the strainer, bulkhead fittings were inserted in the floor of the 82 inch tank to produce flow from the bottom of the strainer. The bulkheads in the Door are visible in Figure 2.2.

2.2 Flow System Four Hayward 1.5 horsepower pumps were used to provide system flow. Each pump could produce on the order of 95 to 100 GPM. Flow rate for the pumps was determined by establishing the time required to fill a container of known volume.

Knowing the total strainer area and that an approach velocity of 0.72 ft/see was required for the test, the corresponding system now rate could then be calculated. To minimize the turbulence from the discharge of the pumps back into the 82 inch diameter tank, return flow was directed into a 36 inch diameter diffuser tank installed above the water

! surface. The center of the diffuser tank was appronimately 30 inches away fmm the tip of the strainer model at the nominal centerline of the tank. Holes were drilled into the bottom of the tank to create a rain effect for water re entry. A photograph of the test apparatus set'up showing the diffuser tank (left side of photograph) and the strainer mounted in the tank is shown in Figure 2.3. If required, flow from an individual pump was regulated through the use of a butter 0y valve. Since there was essentially no change in head loss across the pumps, system flow rate was assumed to remain constant throughout each test. This was confirmed during shakedown testiug when flow rate through the pumps was found to be the same at the beginning and end of a test, t

2.3 Head Loss Pressure drop across the strainer screen was measured through the use of a water filled manometer and recorded manually during testing. One end of the manometer was cannected to a pressure tap insened into the model and the other end to a bulkhead fitting in the side of the tank wall behind the strainer. The pressure tap in the strainer is visible exiting the top of the model in Figure 2.2.

2.4 Instrumentation Minimal instrumentation was required to perform the tests for the program.

Measurements of paint chip size and tnickness were made using commercial grade dial calipers and tape rules. Head loss was measured using a water filled manometer.

Readability on the manometer was +/ 1/16 inch of water. The mass of paint chips used in a test was measured using an AND model FX 300 electronic balance. The balance has a readability of 0.001 grams. The commercial grade accuracy of this instrument was adequate for its use in the test program. The blance was subject to confidence checks during testing.

b 3.0 PAINT CillP DEDRIS 3.1 Paint Tvoc Ameron/Amercoat 90llS two part high performance white epoxy paint was used to crecie the chips for the tests. The raint has a specific gravity of 1.4 1.5.

3.2 Paint Chin Generatior The two part paint was first mixed together according to the manufacturers specifications. A known area (typically 10 foot by 10 foot) of one mil thick plastic shecting was painted and the paint was allowed to cure for at least 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />. The amount of paint that was applied to the sheets was based upon the required thickness of the chips to be produced. The cured paint was peeled from the plastic sheets and its thickness was measured at random locations using a dial caliper. ' Die paint chips were then produced either by breaking the cured paint up by hand or by using a standard household blender, r

3.3 Paint Chit,,mthy ,

The amour' : paint chips used in the test was documented on a mass basis as well as an area bas.. By measuring the area painted and the total mass of the dried paint collected from the area, the weight per square foot of the chips was determined. For the tests docun.ented in this report, three different thickness paint chips were generated: 2 3 mils thick,10 mils thick ar.d 20 mils thick. A random size distribution was used for the chips with the majority of the chips falling into the range between 1/8" x 1/8" to 2" x 2" pieces.

k 4.0 TEST PROCEDURE

SUMMARY

The general test procedure for conducting a head loss test is described below.

Test descriptions and initial conditions were recorded. The required amount of paint chips were then prepared and presoaked to insure they would not float on the water surface when introduced into the tank. The tank was then filled with water to the

.equired height and the pumps primed for operation. The screen area was verified and the required flow rate calculated to give an approach velocity of 0.72 ft/sec. System flow was started and the paint chips were added to the tank under the nominal center of the diffuser with the returning water. Tests continued to run until steady state conditions were observed. Steady state conditions were reached when there was no significant movement of the paint chips in the tank and the head loss across the strainer had been steady for approximately five minutes. Typically, this was about 10 to 15 minutes after introduction of the chips. The strainer head loss was recorded and the strainer photographed. An estimation of the amount of the strainer screen blocked by the paint chips was then performed. Each test was also documented by a video camera. After steady state conditions were reached, the test would be stopped or more paint chips would be added with the flow system continuing to run.

Turbulence in the tank due to return flow patterns caused some chip movement. When flow was terminated upon completion of test 14, the paint chips which had accumulated on the strainer screen immediately fell off of the strainer screen, regardless of paint chip thickness or size. -

' 10 mil and 20 mil) paint chips in the tank. Figure 5.4 was taken after reaching steady state conditions during Test #14 with the final increment for a total of 170 square feet of paint chips in the tank (~56 square feet each of 2 to 3,10 mil and 20 mil thicknesses, j paint chip sizes ranging from ~ 1/8 to 2 inches). Note that some of the strainer screen remains free of paint chips. Figure 5.5 shows the strainer upon completion of Test #14 ,

with flow stopped. Compare Figure 5.5 to Figure 5.4 (the test just completed) and note that all of the paint chips on the strainer screen have fallen off after flow was stopped.

The top of the stral..:: has been marked for clarity.

4 5,3 Full Scale Data Annlication

!- Testing was conducted on a section of a full scale strainer at full scale approach velocities. To determine the amount of paint chips that correspond to the entire strainer.

simply multiply the test amount of paint chips by the area ratio Area fun cde. g / Ares

i.i.ngnn where the full scale strainer has an area of approximately 28 square feet. The

head loss values measured in the tests are the head loss values expected across the entire strainer in the plant. Since the containment floor velocities for the Zion Station are typical to those found in the test tank for this program, it is anticipated that the head loss results obtained in the test program are representative of that to be expected across Zion's sump screens. A plot of the predicted steady state pressure drop versus square feet of i paint chips is shown in Figure 5.6.

Note that the tests conducted in March 1997 and detailed in C.D.I. Technical i Memorandum 97-05 featured a slightly dif0; rent strainer screen area, water level and  ;

approach velocity. Upon completion of the March tests, the strainer screen was removed L from the test rig and coated with epoxy paint at the request of Commonwealth Edison.  :

NOTE The following step stems from an incident where material from the air filters of a te@orary cooling unit plugged the RHR suction strainers in the suppression pool of a BWR (equivalent to Zion's containment recirculation sum st.ainers).

NRC IEB 93 02. Debris Plugging of Energency Core Cooling Suction Strainers, requires action to identify and renove all sources of fibrous material from containment prior to power operation.

In addition to loose material, any item that could become dislodged during a LOCA and potentialiy restrict flow to the containment recirc sump should be evaluated (consider water / steam impingement and weakening of the item and its fasteners by exposure to water / steam).

4. Inspect all areas of containment for material which could potentially clog the containment recirc sum during the recirculation phase of a LOCA. (f/n 2)

Examples:

Cleaning materials.

- Rags. Kim Wipes, paper towels. etc.

Packing materials.

Wire

- Check for wire used in non permanent installations.

(Non qualified installations could result in items becoming dislodged by steam / water impingement and then being swept along to obstruct the sump intake screen).
