1.0 IhTRODUCTION i

h Point Beach Nuclear Plant Unit I steam generators have experienced g

intergranular attack of the tubes in the tubesheet crevice area. A test program was undertaken to evaluate the potential rate of secondarv a

leakage through simulated defective stexn generator tubes in the tube-sheet crevice.

This report details the te: sting which was perfomed to detemine the seccodarj to primary leakage rate through tubes with simulated defects at various locations within the tubesheet crevice. All tests were g

U perfomed with a naninal secondarv side pressure of 1000 psig.

2.0 SlFARY The following strrarizes the results of tests ccapleted to detemine ilew characteristics through defective steam generator tubes durine a postulated loss of primary pressure accident.

1.

Nineteen tests were ccapleted on samplec having defects rancing k

frce a.01 inch diameter hole to a.01" by 3 inch long slit.

2.

The maximum steady state secondary to primar/ flew of 1460 lb/hr.

was obtained with the.01 inch by 1/2 inch defect.

3.

Defects greater than 1/2 inch long were found to reduce in size during test due to external pressure which caused defomatien of the tabe.

4.

Flow is affected by prirary side back pressure.

Increasing the back pressure close to the saturation pressure resulted in a max =um flew that was almost twice as large as that obtained under maximum differential pressure.

8 il 1

TR-ESE-411 8

I I

I 5.

Small defects yielded the maximum flow per unit area. Values ranged from 930,000 lbs. per hour per square inch for the.01 inch diameter hole to 46,000 lbs, per, hour per square inch for the largest defect area tested.

I 6.

An instrunent error analysis showed that all tests were run with the test water entering the simulated tubesheet crevice in the liquid subcooled state.

7.

Defects located 12 inches to 18 inches below the top of the tubesheet have leakage rates approximately 30% less than those located 5/8 inches below the top of the tubesheet.

I 3.0 DETARS OF TEST HARIEARE 3.1 Test Facility Setup The test facility is shown in Figure 1 and was assembled utilizing a 70 gallon autoclave w.ch a nitrogen overpressure to provide a source of demineralized water at 550 F and a pressure of 1065 psig.

The system piping was 3/4 inch stainless steel tubing. Connectors and valves were 3/4 in:h Swagelok. The discharge valve was a 1 1/2 inch fast-acting valve connected to an atcmospheric drain line.

3.2 Instrumentation All instrum.'ntation was calibrated prior to and at the ccxnpletion of the test.

Instrumentation error analysis and calibration data are included as Appendi:: B.

I 3.2.1 Pressure Gaceo I

Pressure gages were installed in the aucoclave (P ),

t tubesheet inlet (P2) and upstream of the discharge I-valve (P3).

3.2.2 Thermocounles I

Thermocouples were installed in the autoclave (Ti),

tubesheet inlet (T ), tubesheet I.D. (T3), and inside th tube adja ent t the defect (T ).

The thennocouples BD were connected to a digital readout.

3.2.3 Flow A Meriam AP gage was connected to a Flow-Dyne venturi flow renter with a 0.1985 inch throat diameter. Connected in parallel to the venturi was a Rosemont AP Transmitter g

WP and a Honeywell 1508A visicorder. This system provided both a visual and permanent record of flow.

For backup flow data, the autoclave level was monitored.

The level was measured using a Rosemont SP transmitter connected to a meter. Using a stonwatch and the level indicat on, the ficw per unit time could be established.

i As the level instrumentation had been calibrated at 68 F, the calculation in Appendix C was used to detennine the 550 F flow rate. Flow rates for the 0.010 inch hole defect were obtained solely by the autoclave level vs. time method.

I 3.3 Test Sectis i

A 21/2 inch diameter carbon steel round was gun drilled to 0.892

.001 inches I.D. to simulate the tubesheet (Figure 2).

Instru-I ment taps and a vent tap were drilled perpendicular to the I.D.

In addition, a tube deflection device was installed to deflect the test tube against the tubesheet I.D. to provide the maximum clearance area at the tube defect.

I Eight strip heaters (of 250 watts each) were utilized to provide heat to the test section and inlet plenun. The test section tem-g 5

perature was stabilized at 600 F prior to initiation of the blowdown.

3.4 Test Specimens B

The simulated steam genera tor tubes (Figures 15 through 22) were fabricated from 7/8 inch 0.D. 316 stainless steel welded seam tubing. The tubes were cut to 24" in length and a plug welded into one end; they were then centerless ground to 0.872 :.001 inches. Tube defects, with the exception et the 0.040 inch hole (3A) and the 0.010 X.500 inch slit (2A), were installed using Electron Discharge machining.

The tube were installed in the test section (tubesheet) usine 8

Swagelok fitti.gs. Defect positioning within the tubesheet crevice was meucured to 1/16 inches.

the defect location fixed. The tube was deflected to contact g

the tubesheet opposite the defect to allow maximum flow area E

at the defect. The system was heated and pressurized frca the autoclave through the specunen tube up to the discharge valve.

Upon reaching test conditions, the system was rapidly depres-surized by opening the discharge valve. Temperature, flow and pressure were recorded before, during, and af ter b1culown.

g An instrument error analysis (Appendix B) showed that all tests 5

were run with the test water entering the simulated tubesheet crevice in the liquid subcooled state.

The testing was pe formed in accordance with Test Procedure 00000-ESE-298, "Wiscansin Electric Power SteLn Generator Tubesheet Crevice Test", (Appendix A).

I 4.2 Observations A total of 19 blowdown tests were perfonned using 9 tubes with various defects. Tests 1 through 12 and 17 through 19 were per-formed with the defect located 5/8 in, frcm the top of the tube-sheet. Tests 13 through 16 were perfonned with the defect located 12 and 18 inches into the tubesheet. Flows with the defect lo-cated at these levels were, respectively, 590 and 500 lbs. per hour less than those with the defect located 5/8 in, into the tubesheet. See Figure 12. Flow rates for the other defects are displayed in Figures 5 through 11.

I The flow rates during the initial ten seconds of each test were higher than those after test stabilization although significantly I

higher (50-100% higher) culy for the first two (2) seconds. This ccrresponded to a freely discharging submerced flow ccudition as 8

7 TR-ESE-411

I I

E the valve was being epened and the back pressure in the test section was being reduced to atmospheric pressure. As the in-ternal tube back pressure decreased and vaporization across the defect w: s established, flew rates stabilized at signifi-I cantly lewer values.

Tube deferrution at the simulated defect uns noted in most of the tubes after test. Tube S/N 4A defect was measured prior to installation at.010 x 1.00 inches. Die tube was then installed and brought to test canditions (550 F 1075 psig) and stabilized for 30 minutes. The 1.D. of the tube was not depressurized,

-I thus no differential pressure was established. The tube was cooled and reinspected. No change in tube diameter or defect area was noted. The tube was then tested normally, af ter wi ich test measurements disclosed a reduction in the defect area of about.005 in: due to tube defornution durins; flow testing.

It was thus verified that the defect reduction was due to the external pressure caused by the depressuriz.ation rather than I

thercul effects.

Figure 15 and Table 1 provide a correlation of the stabilized flow per unit area versus defect area af ter test. A trend seems to be established that the larger defects have lower flow per unit area than the small defects.

The measured flow rates and the defect size effect can be cor-related by equations for critical f1sw through orifices. These correlations are provided in Apyndix D.

For initially subcooled water, Zaloudek (Ref. 1) found that a choking condition occurs at the orifice throat corresponding to the situation when the local pressure reaches the saturation pressure. This is referred to as upstream choking which is characterized by flow consisting I

of a liquid core surrcunded by a vapor annulus. The flow through the orifice remains constant even with further decreases in 'he I

bamk pressure.

This critical flow, Gt, is given by q2 ge c1 (P

For highly metastable flow, the superheated liquid dces not have time to flash and establish themedynamic equilibrium.

In this instance, the liquid flashes dos 1 stream of the orifice leadirg to a second critical flow situatien. The vale of this critical flow is determined frtu the data of Burnell as, sat)

where C2 is a unction of the surface tension.

I Cceparison of '

me.asured flow rates with the predicted values by Eqs. 1 and 1 (n, pmo d: D) showed that the flew rates ter t:x smaller size defects corresponded to G: and those of the large It is thus apparent that with the defects corresponded to Gt smaller flow areas (0.010" hole up to 0.10" x 0.50" slit), surface tension has a strong effect in suppressing flashing and metastable conditions are more apt to occur. Conversely, thermodynamic I

equilibritn is reached with the larger ; low areas. The agreement between predicted and measured values it close (: 15 to 27 percent)

I Increasing the upstream pressure for Tube 2A (bas 3 $ 5) created only a small increase in flow (< 1% increase). This trend is 8

also predicted by Eq. 2; a much larger increase is predicted by Eq. 1.

This supports the conclusion of downstream cheking for this tube.

Figure 13 shows the effect of back pressure on flow for Tube 5A.

In this test, stabilized flow conditions were first established with the back pressure set at atmospheric conditions. The g

5 isolation valve was then slowly closed to increase the back pres-khen the back pressure reached a value in the vicinity of sure.

the saturation pressure (1003 psia), the ficw reached a maximum, a factor 1.8 greater than stabilized ficv rate, af ter which, with further increase in back pressure, the flow decreased to zero corresponding to a decreasing differential pressure as in single phase flow. Due to the difficulty of obtaining steady values of I

flow under high back pressures, the flow versus back pressure data of Figure 13 represent qu.wi-steady state values. Hcuever, the maximum ficv reached can be compared to the maximum theo-retically possible. Since Eq.1 applies for Tube 5A, increasing the back pressure would propagate this pressure increase back towards the orifice and cause the local static pressure to exceed the saturation pressure. Consequently, the choking conditim I

would be recoved, and the flow would be increased by the increase of the discharge coefficient to the single phase value (i.e.,

o.62 to 1.0 or a factor of 1.6).

This provides an explanation of the increase in flev rate.

Two test runs were made to assess the effect of tube clearance within the simulated tubes 5eet. Runs 18 and 19, using the.01 I

by.5 inch long c'efect located 5/8 inches frcra the top, were placed undefle:te" in the test section.

Leakage rates were I

10 TR-ESE-411 I

I B

I generally lower than those obtainea with the maxunum clearance runs but only by a small percentage, approximately 3%. Since other parameters, such as inlet temperature 'nd pressure have a much larger effect, it is concluded that tube ucentricity within the clearances tested does not significannly affect the leakage rates reported.

The test simulated a single tube and the adjacent tubesheet material.

In an operational situation, unless adjacent tubes were also leaking, a larger heat source would be available thus maintaining a higher discharge /tubesheet temperature. This would tend to decrease the tube leak rate.

I

5.0 CONCLUSION

S Based on the test data, it can be seen that the smaller defects yield larger leak rates per unit area. The maximum leak rate per unit area was obtained with the.01 inch diameter hole which yielded about 930,000 lbs. per hour per square inch. The measured leak rates can be correlated to previous data for critical ficw in orifices based on I

upstream choking for the larger defect areas and downstream choking for the smaller defect areas.

An increased leak rate was observed when the simulated steam generator tube was internally pressuri;:ed to near saturation pressure of the wa te r.

The magnitude of this increase for large defects was twice that found while discharging at maximum 6P.

With large defects,12 inches to 18 inch-frcm the top of the tube-sheet, leak rates were reduced as much as 30%. Concentricity of the I

tube within the tubesheet crevice had minimal effect.

1.0 OIL'ECTIVE Ihis procedure details tests to evaluate the potential rate of secon-dary leakage throuch s tmulated defective steam generator tubes in the I

event of a 1DCA. The test section reflects the Point Beach Steam Gen-erator Design in the support plate region.

2.0 TEST HARIL'ARE DESCRIPTION 1hc tests will be performed using a 70 gal. autocalve to provide fluid at the pressure and temperature required.

The test section, Figure 1, will be connected to the autoclave with insulated 3/4 tubing. A venturi will be located upstream of the test section for flow measurement, in addition, a fluid level indicator will be connected to the autoclave for volumetric cceparison.

2.1 Test Section h

The test section will consist of a 2" diameter carbon steel round, with a 0.892

.002 hole through the center to simulate the tube-sheet. Attached to the tubesheet is a 4" section of 1 1/2" sch:

80 pipe which will provide a test fluid reservoir having pressure and temperature measurement capability adjacent to the tube being I

tested.

Strip heaters and a fluid bleed are provided to maintain a test section temperature of 600 10 F prior to testing.*

Pressure gages and thermocouples will be provided at the tube sheet inlet and upstream of the 1 1/2" discharge valve. An addi-I tional TC will be lo ated in the tubesheet adjacent to the test tube.

To be adjusted per cognizant engineer.

8 2.2 Test Specimens The test specimens will be fabricated from 7/8 0.D. x.049 wall welded tubing type 316.

The tubes will be secured to the test section with swagelok fittings. Maximum tube to tubesheet excen-tricity will be maintained during testing using a rod against the tube downstream of the tube defect (except for bot-tan defect). Eight 24" long tube sections will be fabricated with the top end plugged containing the following defects.

Incation Defee t 1.

Center of tubesheet To be detemined later 8.

Bottcm of tubesheet To be determined later 2.3 Test conditions Ideal test conditions at the entrance to the tubesheet are 550 F at 1025 psia. By overcharging the autoclave by approximately 10 100 psi and using a Nitrogen overpressure a pressure of 1100 psig at 550 YF should be Assibic. However, tests will be per-formed to determine the correct autoclave pressure that yields the closest possible test tubesheet inlet temperature 550 and pres-I sure 1065 10 psig.

We We N2 will be applied just prior to initiation of the test.

autoclave will be degassified prior to each additional test.

COMPARISON OF MEASURED AND PREDICTED FILh' RATES Several investigators have observed two distinct types of critical flow of flashin{; water through orifices. The first type occurs with flashing at the orifice throat, termed upstrean choking.

Zaloudek gives o relation for this critical flow (reported in L. S. Tong, Boiling Heat Transfer and Two-Phase Flow, J. Wiley,1965 pp.108-110.

A second type of critical flow occurs when the water in a netastable state exits the orifice and only then flashes. This is downstream choking. The equation of Barne11 or Kinderman & Wales (Also reported by Tong).
