COMPANY CONFIDENTIAL Working Report R 142 38/77 Topic: Number (department/no./year) Results of the non-nuclear hot Of fenbach, 22 March ] 977 test with the relief system in Place, date the Philippsburg nuclear power plant 3245 Gobel R 142 Reference (e.g., project, RGD project): Author Department Tel. Suppression chamber, relief system, II /s/ Frenkel Signature/classifier test results Class File no. Summary This report represents a summary of the loads measured with the relief system during the non-nuclear hot test in KKP. The information relates to:
- the measured pressures and pressure distributions in the sup-pression chamber during vent clearing and condensation; - the loads on the relief system itself, insofar as they are solely of a thermal-hydraulic nature.
The measurement values are transposed to the most unfavorable boundary conditions in the plant and are compared with the speci-fication values. The specification values are not exceeded in any case. There are adequate reserves relative to the specification values. Accordingly, the expert condition of GB 2.6.3-7 of the expert opinion for the pressure relief system /9/ is satisfied.

- 1. Introduction Extensive development tests with the perforated-pipe quencher were performed in the Mannheim Central Power Plant and in the model test stand. The test results are documented in /1,2/.
The relief system'with perforated-pipe quencher was tested under actual conditions and in the actual geometry as part of a non-nuclear hot test in the Brunsbuttel nuclear power plant in October 1974. The test results of those tests are documented in /3,4/. The result of the KKB hot test displayed an adequate margin
'between the measurement results and the specified limits.
Furthermore, tests with the relief system were performed during the KKB nuclear start-up. The measurement results are docu-mented in /5,6,7/. In addition, tests were performed with the relief system during the non-nuclear hot test in the Philippsburg nuclear power plant. Those tests were based on the actual geometry of the relief system. They were performed under plant-relevant or conservative operating conditions in September 1976. The measurement results confirm the measurements of the KKB non-nuclear hot test and the KKB nuclear commissioning. The results display an adequate margin relative to the specifi-cation values. The maximum measured pressure at, the bottom was
+0.48 bar, compared to a maximum specification value of +0.8/-0.57 bar. 18- 3
- 2. Sco e of the tests Vent clearing and condensation tests with the relief system were performed during the non-nuclear hot test in September 1976 in the Philippsburg nuclear power plant. The relief pilot valves were actuated in the relief and safety function.
In order to cover "single failures", the relief valves were also opened with simultaneous actuation of two pilot valves. To measure the pressure profile during clearing of several quenchers, clearing tests were performed with adjacent perforated-pipe quenchers (E, F, G). A total of about 70 clearing and condensation .tests were performed. The operating range in which the relief system was tested is illustrated in Figure 01. The operating range tested in KKB is illustrated in Figure 02. The tests performed and their boundary conditions are shown in Tables 1-7. The actuated relief valves and the associated perforated-pipe quenchers and all the instrumentation are shown .in Figures 1-13. From the tests in KKP it was able to be demonstrated that the measurement results of the non-nuclear hot test and the KKB nuclear start-up test are reproducible;
- any further test series with the relief system would provide no 18- 4
new information concerning the loads on the containment and relief system;
- the load reductions determined for the containment load in KKB are equally valid for KKP; the clearing tests with three adjacent perforated-pipe quenchers resulted in no significant increases of the bottom and wall pressures; the condensation proceeded calmly.
- 3. Pressure load on the su ression chamber 3.1 Vent clearing In the vent clearing tests, the main interest lies on the pressure oscillations that are produced by the expulsion of air from the relief system into the pool of the suppression chamber.
The effect on the pressure oscillations caused by the variation of parameters such as reactor pressure, valve opening time, water pool temperature and condition in the blowdown pipe was examined thoroughly during the KKB non-nuclear hot test. Accordingly, a repetition of these parameter variations was no longer necessary for the KKP non-nuclear hot test. All that remained was the parameter variations caused by the trial operation: reactor pressure, valve opening time, condition in the blowdown pipe ~ The variation of the valve opening time was caused by the different 18 5
opening characteristics of the relief valves and also by the actua-tion of one or two pilot valves. The condition in the blowdown pipe was varied in such a way that the initial conditions in the blowdown pipe with respect to the water level in the pipe were left as they were set instantane-ously (real conditions) or a pressure equalization was brought about by opening the snifting valves so that the water levels in the pipe and in the suppression chamber were the same (clean con-ditions). In the tests with real conditions, the water level in the blowdown pipe was determined by a pressure-difference measurement. As in KKB, no dependence of the pressure oscillations on the 'above-mentioned parameters was found in KKP. A dependence of the pressure oscillations on the clearing pressure was found, as in KKB. Figure 14 shows the measured maximum pressure amplitudes in com-parison to the limits of the scatter band that was measured in the KKB non-nuclear hot test. We note that the pressure amplitudes t measured in KKP fit well into the KKB scatter band. The measure-ment values from test 192 are somewhat above the KKB scatter band boundary. Considering the boundary conditions prevailing for that test (e.g., clearing pressure 21 bar, which was not nearly reached in KKB), the difference is within the statistical error of the test. Figure 15 shows the slight rise of the pressure oscillations with clearing pressure fox "clean conditions", as measured previously 18-6
in KKB. For comparison, the test results with ".real conditions" are also entered in this Figure. No dependence of these bottom pressures on the clearing pressure is recognizable. When the relief valves were opened sequentially at intervals of 5 or 10 seconds, the following pressures were measured at the bot-tom in time order: +0.19/-0.21 bar; +0.21/-0.32 bar; +0.27/-0.32 bar. Thus, the interval test shows a behavior similar to that observed for such boundary conditions in the multiple interval tests in KKB. A slight load increase must be anticipated in the second and subsequent clearing processes /3/. This is probably attributable to the larger amount of air expelled, due to the 4 quencher being only just filled with water. Figure 16 shows the variation of the bottom pressure (DA 10) for "real conditions". Figure 17 shows the same pressure variation for "clean conditions". Zt is clearly evident from the two Figures that, after five oscillations the bottom pressure has fal-len below 0.5 bar and has dropped to values <0.3 bar. According to the expert condition GB2.6.3-9 from /9/, the bottom pressure of 0.5 bar is to be used as a basis for the fatigue analysis as a mean expected load. From the KKP hot test it can be confirmed that this is a very conservative hypothesis. The decay of the clearing oscillations can also be seen at the protective tube. This is demonstrated by DMS 5/6 in Figure 17. The KKP containment is designed to be durable for a pressure load 18-7
of +0.4 bar ) +0.3 bar for loads from the pressure relief system (see /12/) . Figure 18 shows a comparison of the ratio of positive to negative pressure amplitudes based on KKB measurements and theory. The theory is based on the formula
~p os po
* + ETT neg hp pos p0 o KK p KK = pressure in the air space of the suppression chamber BRETT
= hydrostatic pressure corresponding to the submergence
[ETT] of the blowdown pipe. This formula was presented at the 1974 Reactor Convention in the lecture entitled "Depressurization of a boiling water reactor with perforated-pipe quencher; Part 1: Air oscillations during vent clearing". The formula is also the basis of the pressure ampli-tude assignment in the expert opinion for the KKB pressure relief system /8/. A theory describes the primary trend of a process which proceeds under the conditions specified in the theory. In practice, those conditions are falsified by perturbing factors. Therefore, this formula is confirmed in practice only for those events which are large enough to enable possible perturbing factors to be neglected. In the non-nuclear hot test, the pressure ampli-tudes were (+0.4 bar. In that range, the measurement values were scattered about the theoretical curve in KKB also. Only for pressure amplitudes greater than 0.6 did the theoretical curve 18 8
f indicate the trend unambiguously. In principle, therefore, the theoretical relation Qp ~ neg pros b,p
'o
+ p is valid for KKP also.
The negative pressure amplitude measured under extreme conditions (opening with two pilot valves under clean conditions with a valve opening time of 250 ms) was -0.48 bar and thus was sufficiently far from the design value of -0.7 bar. As shown in Figures 14 and 15, the KKP measurement values fit in well with the KKB measurement values. As shown in Figure 15, the pressure amplitude remains (0.8 bar even at the specified clearing pressure of 34 bar. Therefore, the pressure amplitudes in Table 8 from /9/, which were specified on the basis of KKB measurements, can be considered as verified. Figure 19 shows the circumferential distribution of the bottom pressures. The measured circumferential distribution for test 192 is illustrated in the upper part of the Figure. Test 19K was used on the basis of the evaluation of the KKB tests, where bottom pres-sures >0.5 bar were selected for the circumferential distribution, since 'it turned out to be the only KKP test having a comparably high bottom-pressure of 0.48 bar. In turn, the selection of the pressure magnitude is based on the fact that perturbing influences 18- 9
can be minimized only for relatively powerful events. Thus, what was already said concerning the ratio of positive to negative pressure amplitudes applies here also. The 1/R law in the circumferential direction was able to be con-firmed with the KKB tests. For the KKP tests, Figure 19 shows that the 1/R law was also able to be confirmed in test 19Z. In this circumferential distribution it is assumed that the pressure remains constant. within the circumscribed circle having the radius of the quencher. In the bottom part of the Figure it is shown that the 1/R circum-ferential distribution, based on the specification value of 0.5 bar (see Table 8), represents an upper envelope for normal response of the relief system for all KKP tests. As already <shown in Figure 14, the load reduction found at the spherical shell in comparison to the values at the L-joint in the vicinity of the quencher is also verified in the KKB hot test. As part of the vent clearing test program, a few tests were run in which three adjacent relief valves were opened simultaneously., The measurement results show that this causes no increase of the pressures. Furthermore, there were also no differences in the pressure distributions in the meridional and circumferential directions compared to the single-valve tests. The pressure values measured in the multi-pipe tests are entered as crosses in Figure 14. 18- 10
On the whole, it can be stated that the vent clearing tests in Philippsburg have fully confirmed the KKB measurements in regard to the pressure amplitudes and pressure distribution. Thus, the suppression chamber loads according to Table 8 were able to be verified for the clearing of the pressure relief system. 3.2 Condensation The condensation tests were so performed that condensation occur-red through one or two quenchers at reactor pressures of 70-11.5 bar and with the quenchers provided only in the automatic depres-surization mode II at reactor pressures below 11.5 bar. A maximum harmonic pressure oscillation of +0.18 bar was measured (see Figure 20). This is below the specified condensation pres-sure of +0.2 bar. The frequency was approximately 80 Hz. At re-actor pressures below 11.5 bar, pulsating condensation occurred. The pressure spikes measured then had a maximum value, of 1.2 bar with a base width of <2 ms. Because of this small duration of action, the pressure spikes have no effect on the stresses in the structural members of the suppression chamber (see Figures 21, 22) . The temperature distribution in circumference and elevation ex-hibited a mean deviation of +4.5 C in the condensation tests. On the whole, the condensation proceeded calmly and exhibited the results already measured previously in KKB.

4.1 Vent clearing pressure Pronounced clearing pressures were measured only in three tests. The reactor pressure was approximately 70.5 bar. The measured maximum clearing pressure was approximately 21 bar with a valve opening time of approximately 250 ms. Figure 23 shows the extrapolation to 88 bar reactor pressure and 100 ms valve opening time based on the measurement values. The computation results for the reactor pressure of 70.5 bar and the corresponding valve opening times envelop the measurement results. Thus, the basis of the extrapolation is conservative with respect to the clearing pressures. The maximum clearing pressure calculated on that basis is 29 bar. Th's value is clearly smaller than the specified clearing pressure of 34 bar. 4.2 Steady-state pressure The steady-state pressure in the quencher's vicinity is plotted versus the mass flow density in Figure 24. Zt can be seen that the maximum steady-state pressure for a reactor pressure of 88 bar is approximately 13 bar. This value is below the value of 16 bar specified for the quencher. 4.3 Vertical force on the blowdown 'aipe To measure the vertical force on the blowdown pipe, two strain gauges each in the circumferential and vertical directions were 18- 12
mounted in the water region (see Figure 2). The evaluation technique used to infer the vertical force from the measured stresses and to perform the extrapolation to 100 ms valve opening time and 88 bar reactor pressure based on the available measurement results is described in /7/. The evaluated measurement results for the three informative tests are shown in the following Table: Test Reactor Valve Pipe Vertical pressure opening pressure force time bar ms bar kN 70.8 816 t?]* 180 8 70 616 7.5 190 19Z 71 255 21 385 The extrapolation to 100 ms valve opening time and 88 bar reactor pressure results in a vertical force of approximately 600 kN. P The specification value of the vertical force is 700 kN. There is an adequate margin between the specification value of 700 kN and the extrapolated value of 600 kN for the vertical force. 4.4 Forces on the struts of the protective tube The maximum strut force was measured in test 19Z at a clearing pressure of 21 bar and a valve opening time of about 250 ms. It was 85 kN. t
*Tr. note: First digit not clear in German document.
18- 13
This force is composed of three factors:
- 1. Pressure difference across the vent pipe
- 2. Pressure I difference across the protective tube
- 3. Displacement of the pivot point of the struts on the inner cylinder.
All three factors together yield the total force. The measured total force must be viewed in terms of the load case on which the design is determined. That case is not. the clearing of the relief system, but rather air-poor condensation at the vent pipes. A temporal coincidence of the two load cases was excluded by the premature automatic depressurization. The external force on a strut of the inner cylinder for the load case of air-poor condensation is 195 kN /10/. This force is larger by a factor of'.3 than the measured force of 85 kN on the struts of the protective tube. The difference between the two values seems to be large enough, so that it can be stated that the load case of air-free condensation conservatively envelops the load case of vent clearing.
-3 inner For the probability of occurrence of 10 /LOCA, a maximum strut force of approximately 230 kN was demonstrated in /ll/.
This force is greater by a factor of 2.7 than the force of 85 kN measured in KKP and can surely still be supported by the struts. 18-14

- 2. Introduction In accordance with the goals set in the Test Specification /1/,
primary emphasis in the KKB non-nuclear hot test was on pre-operational testing or the behavior of the SRV, the behavior of the components of the pressure relief system,
- the magnitude and distribution of pressures in the suppression chamber .
The test results relevant to these subjects are discussed separately in the following Sections. Comments are made only when necessary to understand the Tables and Figures.
- 3. Test arameters We shall dispense here with a detailed description of the test arrangement and instrumentation, which are reported upon at length in /1/.
The overall arrangement of the pressure relief system inside the pressure suppression system is shown in Fig. 1. The arrangement of the 8 SRV and the blowdown quenchers A-H in the suppression chamber is shown in Figure 2. The most important measurement transmitters for evaluating the pressure relief system and their exact positions can be seen in Figures 3 and 4. Those Figures show the pressure relief system with blowdown quencher F on the 260'eridian, on which most of the blowdown tests were concentrated. For further identification of the measurement transmitters. and their positions, we refer here once again to the Test Specification /1/. 19-3
A complete list of the test parameters is given in Tables 1-7. They include the relevant parameters for the blowdown tests: blowing SRV and quenchers,
'type of actuation, liquid level in blowdown pipe before beginning of test, pool temperature before beginning of test, test duration, reactor overpressure at beginning and after end of test, liquid level in suppression chamber, liquid level in RPV before beginning of test, steady-state flow rate.
- 4. Behavior of safet /relief va ves Zn order that the pressure in the RPV not rise impermissibly, e.g., in the event of a failure of the main heat sink, the valve opening time of the SRV may not exceed 1000 ms with an additional dead time of 500 ms. Figure 5 shows diagrammatically the definition of all dead times and opening times of the pilot valves and SRV.
4.1 Dead and opening times of the safety/relief valves Listed in Tables 8 14 are the results of the vent clearing tests at ca. 70 bar reactor pressure for SRV "A - H", divided according to the excitation of the SRV by relief ilot valve or safet ilot valve and also relief ilot valve and safet A comprehensive survey of the measured valve times is given in 19-4
l Table 15. Figure 6 exhibits these results once again with respect to the scatter of the valve opening times for valves B, D, F, H and'he excitation by means of 1 pilot valve or 2 pilot valves. 4.2 Typical lift/time variations Figure 7 shows a comparison of theoretical and hypothetical lift/time variations with measured opening characteristics. Besides the lift/time variation determined computationally by the manufacturer of the SRV, the idealized variation used for precalculations and the variation assumed for extreme hypo-thetical accident conditions (jamming valve), we have also drawn in three of the lift/time variations that were measured in the vent clearing tests and which are representative of the following cases: quick-opening valve (test 19 2), normal-opening valve (test 18), slow-opening valve (test 28). By selecting the quickest and slowest of the measured lift/time variations, we simultaneously get the upper and lower envelopes for the experimentally determined opening characteristics.
- 4. 3 Flow rate of SRV Table 16 is a comparison of the required total flow rates during the valve opening phase and the total flow rates determined from the discharge coefficients (< values, Figure 8) in accordance with the lift/time variations. One representative test each was selected for valves B, D, E, F, G, and H. According to 19-5
that, the actual steam flow rates are higher than the required values. Figures 9 and 10 show two supplementary examples of measured lift/time variations and the corresponding flow rate/time variations based on the < calculations, with which the required and the specified flow rate/time variations are compared.
- 5. Load on the structures of the su ression chamber The pressure values indicated in Tables 17 31 represent maximum values of the measured dynamic pressures during the vent clearing phase.
The following subdivision was made: Pressures in 260'eridian in Tables 17 19, Pressures in 244'eridian in Tables 20 22, Pressures at periphery of the conical bottom in Tables 23 25, Pressures at periphery of spherical shell in Tables 26 28, Pressures at the inner cylinder in Tables 29 31." To clarify the pressure distributions in the meridian cross-section at 260', Figures 11 14 show representative examples for the different types of tests: Figure ll Distribution during vent\ clearing with quencher F at a reactor pressure of ca. 50 bar. Figure 12 Distribution during vent clearing with only one quencher (F), with two adjacent quenchers (F,G) and three adjacent quenchers (E,F,G) at. a reactor pressure of ca. 70 bar. 19-6
~ r Figure 13 Distribution during vent clearing with three adjacent quenchers (E,F,G) and reactor pressures of ca. 45 bar and 70 bar.
Figure 14 Distribution during the vent clearing phases of an interval test with quencher F. Figure 15 shows the measured circumferential distribution of the bottom pressures. Xt turns out that the 1/R circumferential distribution, based on the specified value of 0.5 bar for normal response of the pressure relief system, represents an upper enve-lope for all KKP l blowdown tests.

For conversion of the strains measured at the various components of the pressure relief system into stresses and forces, the appropriate conversion factors for the individual measurement points are listed in Table 32.. The strains indicated in Tables 33-42 (and stresses or forces) represent the maximum values measured during. the vent clearing phases. The strains and stresses at measurement points DMS 15/16 and DMS 17/18 are an exception. Those values are correlated in time with the corresponding vent-clearing pressures. Tables 33-36 contain the measured dynamic strains, stresses and deflections of the blowdown pipe and cladding tube. Tables 37-40 contain the measured dynamic strains, stresses and deflections of:the perforated-pipe quencher and bottom mount. 19-7
Tables 41 and 42 contain the measured dynamic strains and forces W in the struts of the cladding tube.

- 1. ~Summar A total of 29 tests to investigate the air oscillations after vent clearing were performed in the AEG condensation test stand in the Mannheim Central Power Station (GKM). The tests were carried out with a single NW 150 or NW 200 pipe and with an NW 150 double pipe. The vent pipe submergence and the valve opening time were intentionally varied.
It was found that the pressure peaks beneath the central pipe are at most equal to the pressure in the vent pipe at the time of the vent clearing. When plotted against the valve opening time, the measurement points representing the pressure peaks fall along a uniform curve. No significant influence of the submergence or pipe geometry is revealed. The tests show further that the assumption of an additive superposition of the central pressure peaks, as was made in the Loading Specification for the KWW suppression chamber bottom, is conservative.
- 2. Statement of the roblem When a relief valve is blown down, the water slug located in the pipe has to be expelled during the flow initiation process.
A cushion of compressed air is formed between the water slug and the steam flowing behind it. When this air cushion emerges from the pipe, it begins to expand rapidly. Physical models that provide -good agreement with experimental results have been described previously in /l/ and /2/. Zn this report, test results shall be used to investigate the quantities that. have a substantial influence on the pressure peaks of the gas bubble oscillation. Xn addition, the pressure profile at the bottom of the tank during simultaneous blowdown through a double pipe having a pipe separation of 600 mm is compared with the profile for a single pipe.
The vent clearing tests were performed in the GKM test stand illustrated in Figure 3.1. This test stand is used for vent clearing and condensation tests. A detailed description of the test stand is contained in /3/. The test stand is connected to the steam system of the GKM via an NW 200 pipeline. Superheated steam at 20 kg/cm 2 (gauge) and ca. 280'C can be obtained from that system. An NW 200 repair gate-valve, which is mounted directly on the steam header, represents the beginning of the experimental section and simultaneously delimits the test stand from the GKM. An actual KWW relief valve is located approximately 25 m down-stream from this repair gate-valve. After opening the relief valve, steam is conducted into the following vent pipe and condenses in the water pool of the test tank. Some of the tests described here were performed with the test set-up using a double pipe, as illustrated in Figure 3.2. In the vicinity of the distribution point from the single pipe to the double pipe, the off-center pipe could be sealed off from the rest of the test stahd by means of a pipe blanking disk. The most important dimensions and instruments are shown in Figures 3.1 and 3.2.

- 4. Com ilation and inter retation of the GKM test results Vent clearing tests were performed in GKM on a vent pipe with mass flow densities such as those that occur when a relief valve is blown down. The measurements were made on a single pipe (NW 200 or NW 15) and on a 2 x NW 150 double pipe. Besides the vent pipe submergence, the valve opening time was also varied in the tests. All tests performed to investigate the vent clearing process in GKM are compiled in Table 4.1 togther with the parameters of greatest importance for the vent clearing process.
4.1 Dependence of the pressure peaks on the pressure build-up in the vent pipe (vent clearing pressure) During the vent clearing process, there is a pressure build-up in the vent pipe. It causes an acceleration of the water column standing in the pipe, but simultaneously also causes a compression of the air column. At the instant of expulsion of the water column (either the water slug is expelled in its entirety or the following air bores a channel in the water pool), the ai column is under maximum compression. Therefore, it may be expected that the maximum overpressures during the subsequent air oscillations do not exceed this vent clearing pressure. The investigations relating to this question are summarized in Fig. 4.1. In that Figure, the measured pressure peaks beneath the pipe (beneath the central pipe in the double-pipe configura-tion) in the second oscillation are'lotted versus the vent clearing pressure. The second oscillation was used for the evaluation because it is in the second oscillation that the
larger overpressures occur, even compared to the first oscillation. The first expansion of the air bubble probably already begins before the entire volume of air has left the vent pipe. Accordingly, energy continues to be fed in during the first oscillation, so that the second pressure peak can be higher. Figure 4. 1 shows that the measured pressure peaks at the bottom were found to be at most equal to the vent clearing pressure. The condensation shocks, which are superimposed on these pressure I peaks and falsify the result, were not taken into consideration here. However, most of the measurement points were found below the vent clearing pressure, which can be explained by the fact that a damping had already occurred in the second oscillation. Finally, it should be noted that no significant differences were found with respect to the nominal bore, submergence and number of pipes. 4.2 Dependence of the pressure peaks on the valve opening time In the preceding Section, a relation was found between the pressures measured at the bottom beneath the pipe during the air oscillations and the pressure in the vent pipe at the instant of vent clearing (vent clearing pressure). However, the vent clearing pressure is not a very suitable magnitude for practical applications. In searching for a more suitable physical magnitude, the following analysis is relevant: The pressure build-up in the vent pipe is surely dependent on the time variation of the valve opening process. It is therefore
obvious to investigate 'the dependence of the pressure peaks on the valve opening time. The last tests, in which the displacement-vs.-time function of the valve piston was measured directly, revealed the following problem concerning the valve opening time: In slow opening processes, the valve lift does not increase linearly with time. Instead, there can be a slower increase at the beginning and at the end of the opening process, as is illustrated in a graph in Figure 4.2. In the earlier tests, some of which were discussed .in /3/, the valve opening time was determined by another method. There, a valve opening time was extrapolated linearly by using 2 contacts which were separated from the upper and lower end points (Figure 4.2). The start and gradual end of the valve lift process are disregarded in that method. The switching point. of the contacts is not very exact and thus represents an additional uncertainty. Therefore, the valve opening time was determined from the pressure before the orifice which precedes the valve. The dependence of t the pressure peak beneath the pipe during the same oscillation on the valve opening time determined in that way is illustrated in Figure 4.3. The measurement points yield a uniform variation which is approximated by a curve drawn through them. For short opening times, high pressure peaks are produced, but they decrease very quickly as the valve opening time is increased and tend toward a low limiting. value for very slow valve opening processes. No significant influence of the submergence, the lo
pipe nominal bore or a superposition due to the second pipe can be found from Figure 4.3. 4.3 Pressure profile at the bottom for the single and double pipes Figure 4.4 shows a comparison of the pressure profiles at the bottom for a single pipe and a double pipe. Both tests were performed with a submergence of 4 m and approximately identical valve opening times. Approximately the same pressure peaks were found centrally, as shown in Figure 4.4. In regard to the superposition of loads caused by 2 pipes blowing down simultaneously, a statement was already made with Figure 4.3. Both for the NN 200 and NN 150 single pipes and for the Nid 150 double pipe, the pressure peak beneath the central pipe was found to depend only on the valve opening time. Hence, no superposition of the pressure peaks occurs. However, the Load Specification for the KWN suppression chamber bottom, described in detail in /4/, is based on an additive superposition. Thus, the tests performed in the GKN with single and double pipes demonstrate that that Load Spec'.fication is conservative.

Introduction The purpose of the report is to provide a comprehensive survey of the relief system. Important relationships in regard to the system's use are made clear and the require-ments on individual components are justified. The indi-cation of very specialized data and information was in-tentionally dispensed with for the sake of a better survey and, instead, reference is made to detailed reports and specifications. This facilitates the search for detailed information. 8-5
Descri tion of the relief s stem Two relief pipes branch off from the main-steam lines in the upper annulus of the drywell. They lead into the suppression chamber, which is partially filled with water, and are sub-merged in the water pool (Figure 2.1) . This system, called the relief system, is used to relieve the pressure in the reactor pressure vessel in the event of accidents (e.g., failure of the main heat sink). For that purpose, main steam is blown into the water pool of the suppression chamber and is condensed as water. The total of 7 relief lines, which are equipped with quick-opening valves, are connected to the main-steam lines inside the drywell. Figure 2.2 shows the relief system beginning at, the valve. Xt consists of the relief valve, restraining structure, blowdown pipe, perforated-pipe quencher, bottom mount and protective tube. Each of the 7 main valves is equipped with two separate pilot valves (Figure 2.3) which can be actuated either by internal means (steam) or by external means (electromagnetically) . Figure 2.4 shows a section through the spring-loaded pilot-operated safety valve. After opening the control valves, steam flows from the reactor via the control line into the pressure chamber of the main valves and the valve opens. The valves are arranged in three groups which are actuated at different reactor pressures (Section 3.1). 3 valves are 8-6
I provided for the automatic depressurization mode (Section 3.1). The arrangement of the safety-relief valves is illustrated diagrammatically in Figure 2.5. From the Figure it is ob-vious that the various groups of valves are distributed uniformly over the circumference of the suppression chamber. The 3 valves which are actuated for automatic depressuriza-tion are also distributed along the circumference. ln this way, adjacent valves are not actuated simultaneously (except P in the safety mode (Section 3.2)) and the pool is heated uniformly when there is a high thermal load. A fitting with an orifice plate is connected to the relief valve. It is followed by a second fitting with two connec-tions for snifter valves, to which is connected the blowdown pipe with a nominal bore of 400 mm (Figure 2.2). The orifice plate is meant to generate a steam velocity which is uniform in time and space by limiting the extent. of the supersonic "braid" emerging from the valve. The snifter valve opens at. a low adjustable underpressure in the blowdown pipe with respect to the pressure in the drywell and allows air to flow in so as to equalize the pressure. Large fluctuations of the water column in the blowdown pipe can thereby be avoided. More details of this process are described in /1/. 8-7
The blowdown pipe widens in the suppression chamber to an inside diameter of 555 mm and is drawn in again to a nominal bore of 400 mm at the water level. The submergence of the quencher is about 4 m with respect to the normal water level and centerline of the quencher arms. Figure 2.6 shows the construction of the perforated-pipe quencher which is rigidly connected to the blowdown pipe. The central member of the quencher between the blowdown pipe and the 4 quencher arms is a ball. The angles between the arms are so chosen that favorable installation conditions are achieved in the suppression chamber (Figure 2.7). The perforated-pipe quencher is built with a total of 2216 bores of 10 mm diameter. Two quencher arms, which point in the same circumferential direction, each have 88 thrust bores in the arm bottom in order to produce a circulating flow in the suppression chamber so as to obtain a uniform temperature mixing of the pool water. The 8 hole arrays themselves are arranged symmetrically and thus in a neutral-force manner on the sides of the quencher arms. The installation conditions and arrangement of the perforated-pipe quenchers in the suppression chamber are shown in Figure 2.7. The perforated-pipe quencher makes possible a calm condensation up to high pool temperatures (> 80') and re-duces the pressure oscillations which occur during clearing of the blowdown pipes. 8-8
The blowdown pipe is surrounded by a protective tube in the area of the suppression chamber. The protective tube is mounted in the top head of the suppression chamber and in the area of the catwalk is supported in the brace with the vent pipes. Below the water level, the protective tube is led in a water-tight manner to the spherical central member of the perforated-pipe quencher welded to the blowdown pipe. Near the quencher the protective tube is tapered and forms an annular gap there with a width of 10 mm. The task of the protective tube is to prevent the emergence of steam into the air space of the suppression chamber in the event of a leak in the blowdown pipe and thus to maintain the operation of the pressure suppression system. The restraining structure near the valve represents the anchor point of the relief system. A diagrammatic illustration is shown in Figure 2.8. The bottom mount is fastened to the sandwich structure by webs. The connection between the perforated-pipe quencher and the bottom mount is so designed that a displacement of the perforated-pipe quencher in the vertical direction due to thermal expansion of the blowdown pipe is possible (Figure 2.9) . The task of the bottom mount is to guide the system and to absorb the transverse forces and moments about the vertical axis which act on the quencher. 8-9
Use of the relief s stem The description given here is taken essentially from /1/. The safety/relief valves protect the pressure vessel in the event of pressure excursions. They prevent the reactor pres-sure from exceeding 1.1 times the pressure-vessel design pressure, even from maximum possible pressure transients. Xn the event of a loss of coolant and failure of the coolant injection system in the automatic depressurization mode, the valves also provide for a lowering of the reactor pressure in order to make possible the injection of water by the RHR system and the core spray system. The valves are also used briefly together with the turbine bypass systems in order to prevent a shutdown of the reactor in the event of a "Turbine tripout" or "Load rejection" accident. The main valves have a dual function as combined safety and relief valves. The pilot valves open electromagnetically both in the safety function and in the relief function. The main valves are opened and kept open by internal means. Due to the higher response accuracy, the electrical control sys-tem permits a more exact excitation of the valves and thus a closer staggering of the response pressures in the event of pressure excursions. The electrical control system also makes it possible to open the valves and keep them open, as is necessary for automatic depressurization and when they are used together with the turbine bypass system. The pilot 8-10
'i solenoid valves also receive a pneumatic supplementary load -which is controlled via separate solenoid valves. This second external energy source, in combination with the elec-trical system, which is installed for the opening process, permits a very exact. closing of the valves. Use for relief function The main valves are opened by one of their two control valves in the following cases: Turbine tri out Because of the limited capacity of the turbine bypass system (75% of the nominal steam flow rate), 1 valve opens for ca. 5 sec at a reactor power of 80 90% full load and 1 addi-tional valve opens for ca. 10 sec at )90% full load. These two valves are designated by TSS in Figure 2.5 and are actuated directly from the Geamatic. The reactor pressure is thereby held at 70 bar. Hi h reactor ressure If the reactor pressure rises impermissibly due to failure of the control system or components, e.g., in the event of a turbine tripout caused by failure of the main condenser, then the relief valves, staggered in three groups, open at the following set pressures: 8-11
( 1st group, 74.3 + 0.5 bar, 1 valve 2nd group, 74.8 + 0.5 bar, 2 valves 3rd group, 75.5 + 0.5 bar, 4 valves in order to handle this pressure transient. The-'time varia-tion of the reactor pressure is plotted in Figure 3.1 to-gether with an indication of the response marks for scram and safety/relief valves. The following boundary conditions are applicable: failure of the main heat sink reactor at nominal load reactor shutdown due to high neutron flux and control-rod fast-insertion time of 5 sec. A detailed description of the transient operational and acci-dent behavior is contained in /7/. Hold at ressure and tern erature when the main heat sink is not available Following the scram, the residual heat is removed by periodic opening of several valves in the first 15 seconds and 1 valve thereafter. Emer enc shutdown when the main heat sink is not available The reactor is depressurized in 5 hours by repeated manual opening of one valve according to a prescribed pressure vari-ation. 8-12
Automatic de ressurization in the event of loss of coolant In the event of a loss of coolant, one relief valve is opened automatically in any event in order to depressurize the system gradually. This occurs only if the liquid level in the reac-tor pressure vessel is high enough and, at the earliest, 10 minutes after appearance of the accident criteria. At a reactor pressure below ll bar, 3 relief valves are opened in the event. of a loss of coolant in order to create a closed emergency cooling loop: suppression chamber pump reactor suppression chamber. Finally, the depressurization system is used as a redundance for the coolant injection system. If the coolant injection system does not convey a sufficient amount of water into the reactor when needed, then 3 relief valves are opened in order to bring the low-pressure emergency cooling systems quickly into use by means of a rapid lowering of the pressure. Performance test Each valve can be actuated individually by hand during opera-tion. 3.2. Use for safety function In the improbable event that several valves should not open in their relief function during a reactor pressure transient, 8-13
the control valves open the main valves in the safety func-tion on the basis of a reactor pressure of 81.5 + 1.5 bar. 8-14
e
- 4. 0 erational boundar conditions The relief system must satisfy the following boundary condi-tions in regard to the reactor pressure regulation and the effect on the pressure suppression system. This description represents an extension of the compilation of operational boundary conditions previously contained in /1/.
4.1. Blowdown capacity The nominal flow rate of one relief valve is 600 t/h at a reactor pressure of 83 bar.* This flow rate is utilized, in accordance with the relevant standards, as a basis for the calculation of reactor pressure transients which are covered by the safety function. A value of 600 t/h at 70 bar reactor pressure is expected for the actual flow rate by the valve manufacturer. The flow rate actually expected by the valve manufacturer is shown in Figure 4.1 as a function of reactor pressure. The design of the pressure relief system, especially the perforated-pipe quencher, is based on this flow-rate variation. At high reactor pressures, a critical pressure ratio prevails above the seat of the safety/relief valve. The flow rate through the valve is then determined by the reactor pressure and is approximately proportional to it. Xf the reactor pres-sure drops to low values, then the pressure above the valve
" Translator's note: t = metric ton = 1000 kg 8-15
seat finally drops below the critical pressure gradient and the flow rate decreases superproportionally with the reactor pressure. Since the blowdown capacity plays an important role at lowered reactor pressure for the automatic depressuri-zation mode described in Section 3, the flow rate per relief valve for low reactor pressures was plotted in Figure 4.2. The upper curve corxesponds to the flow rate through the valve as indicated by the valve manufacturer. In the plotted range of reactor pressure, these values also apply in prac-tice for the flow rate through the relief system with the perforated-pipe quencher inserted further on. The reduced flow rates illustrated in the lower curve occur for a pressure of 2.8 kg/cm (absolute) in the air space of the suppression chamber. The flow rate through the xelief system at lowered reactor pxessure is only slightly influ-enced by the perforated-pipe quencher (for reactor pressures <- 5 kg/cm~ (absolute)) but more strongly by a rise of the suppression-chamber pressure. The variation of the liquid level inside the core shroud during the automatic depressurization following a 44 cm 2 leak and failure of the coolant injection system is plotted in Figure 4.3. The illustration makes it clear that the liquid-level variation is favorably influenced at elevated pressure in the suppression chamber. This result is due to the fact that in the event of an elevated pressure in the 8-16
suppression chamber, the low-pressure coolant injection sys-tem can already inject coolant at a higher reactor pressure and can convey more coolant at the same reactor pressure. The reduced flow through the relief valve is thereby over-compensated. As the accident proceeds further, heat is also removed to an increasing extent via the injected cold water and an additional lowering. of the pressure is effected. 4.2. Openinq of the valves In order that the pressure in the reactor pressure vessel not rise impermissibly, e.g., in the event of failure of the main heat sink, the valve opening time of the safety/relief valves may not exceed 1 second with an additional dead time of 0.5 second. According to the measurements with K%1 valve /8/, the expectation value of the opening time is about 300 ms. However, shorter opening times down to 100 ms must not cause impermissible loads (in this regard, see Section 6). The valve opening time is defined as the total setting time of the valve.'uring the opening process, the flow rate increases in pro-portion to the time. 4.3. Water level and submergence The nominal water level is plotted in Figure 2.2. The sub-mergence of the quencher relative to the arm axis is 3.975 m for normal water level in the suppression chamber but the sys-tem must also remain operable for deviations of +0.40 and 8-17
-3.00 m in the water level; the latter, of course, in the event of sharply reduced reactor pressure (see Figure 4.4). Detailed information is contained in /6/ concerning the con-densation of the steam when the quencher submergence is very small. When the depth of the water covering the quencher arms is only 1 to 2 arm diameters (40 to 80 cm), a steam flow rate of 600 t/h can still be condensed completely. An appre-ciable lowering of the water level below the nominal value occurs if the suppression pool water is used for core flooding. The lowest water level occurs in the event of a so-called runout of the suppression chamber. Zn the event of a suppres-sion chamber leak having the size of a connection line, the relief system must still be capable of permitting an auto-matic depressurization. In this case, at least the design pressure of the containment must not be exceeded. Figure 4.4, taken from /1/, shows the decrease of the flow rate with decreasing water level in the suppression chamber. Temperature distribution in the suppression chamber during relief processes A most uniform possible temperature distribution of the water in the suppression chamber is necessary because then the heat capacity of the water is better exploited and thermal stresses at the walls and bottom due to nonuniform heating are avoided. 8-18
J In order to achieve a uniform vertical temperature distribu-tion, the perforated-pipe quencher was installed very deep in the water space of the suppression chamber (Figure 2.2). The warm, specifically lighter water rises, mixes with the colder water situated above it and a uniform heating of the pool in the vertical direction is obtained. Due to a strong large-scale turbulence in the pool, which is generated by the flow processes and condensation processes at the quencher, a suf-ficient quantity of heat is also delivered to the water below the quencher /1/. A uniform mixing in the circumferential direction is achieved by the thrust bores in the bottoms of two arms pointing in the same circumferential direction. The water is set into a slow motion by this one-sided impulse on the water mass. An important active element for the mixing of the pool water is the recirculation cooling system. After an averaged pool temperature of 36' is exceeded, water is taken from the lowest point of the pool, cooled and carried back, distributed over the circumference of the suppression chamber, via four RHR legs near the water surface. In this manner, a recircu-lation of the suppression pool water is effected every half hour by the four RHR legs shown in Figure 2.5. This measure alone already produces a uniform temperature distribution, since the emergency shutdown of the reactor is extended over 5 hours, for example, i.e., over a 10-times-longer time. 8-19
On the basis of the numerous investigations performed in /l/, it can be assumed that the maximum deviation of the -tempera-ture in the pool of the suppression chamber does not exceed
+5', except for regions in the immediate vicinity of the steam outlet. This difference should be maintained even if the pool is heated by 20' by one or more blowdown lines during a blowdown process and, simultaneously, 2 out of 4 RHR system pumps are in operation.
The temperature range of the pool water in the vicinity of the quencher at which the blowdown can be effected with full flow rate should be at least between 35' and 60'. With a linearly decreasing flow rate, it must still be possible to pass through the temperature range from 60' to 80' according to Figure 4.5. This stipulation was based on a mean pool temperature of up to 55' for full flow rate and a maximum permissible mean pool temperature of 75' and the above-mentioned nonuniformity of the water heating. 4.5. Permissible pressure loads on the suppression chamber A distinction is made between two types of loads which gener-ate pressure loads on the suppression chamber during opera-tion of the blowdown lines. First, after opening the valve the water slug in the blowdown pipe is expelled, whereupon the air in the pipe is compressed. When this air is expelled, brief pressure oscillations are generated which act on the bottom and walls of the suppression chamber. This process C is described in detail in /5/. The pressure loads to be 8-20
expected are also indicated there. Second, pressure oscil-lations which depend on the steam flow rate and the water temperature occur during the steady-state condensation of steam. A detailed description of these processes and the expected pressure amplitudes is contained in /1/. Both loads are to be limited to the following limiting values in the plant: 4.5.1. Pressure oscillations during vent clearing For a reactor pressure of up to 88 bar and for the specified valve-opening times, the air oscillations on the bottom and wall should not exceed the value
+1.45 kg/cm and -0.4 kg/cm globally
-0. 6 kg/cm~ locally during blowdown of all valves in the safety function.
4.5.2. Pressure oscillations during condensation For the specified range of flow rate and temperature, the pressure amplitudes on the bottom and wall should be kept below +0.4 atm. 8-21
- 5. Re uirements on individual com onents The requirements which should ensure the operation and utili-zation of the individual components are compiled in this Section, taking into consideration the design details of the pressure suppression system. In addition, an extract from the specifications for the individual components is reproduced.
However, only the most significant loads are considered and reference is made to the individual specifications for the others. 5.1. Relief valves The safety/relief valves are used for pressure limitation in the event of accidents with a pressure rise in the reactor pressure vessel and for pressure relief in the event of loss-of-coolant accidents. The requirements with respect to re-sponse pressures, opening times and blowdown capacity and the data determinative for the design are indicated in /2/. 5.2. Perforated-pipe guencher and blowdown pipe The processes during vent clearing and the model extended for the perforated-pipe quencher to calculate the clearing pres-sure are described in detail in /5/. The pressure profile in the blowdown pipe during clearing due to pressure transients (88 bar reactor pressure) is plotted versus time in Figure 5.1. For an extremely short valve-opening time of 100 ms, a maximum possible pressure of 31 bar 8-22
results in the blowdown pipe, conservatively neglecting the rate of condensation of the inflowing steam at the pipe wall and at the water surface. For an assumed 208'eduction of the outlet area of the quencher, the steady-state pressure in the nozzle is l6 bar. 6000 response cases (produced primarily in the "Hold at pressure and temperature" accident) arise with respect to,, the valve actuated in the first valve group. A total of 5000 clearing processes result from this accident. All other response cases together, such as emergency shutdown, depressurization, etc., then amount, to 1000. The other requirements relating to the load on the perforat-ed-pipe quencher and blowdown pipe are specified in /3/ for the operating conditions vent clearing steady-state condensation and intermittent condensation. 5.3. Bottom mount The bottom mount of the quencher (Figure 2.9) is so con-I structed that the flow around the quencher arm is not impaired. The task of the bottom mount is to absorb the transverse forces and torsional moments acting on the quencher during the clearing process and steady-state condensation. The val-ues applicable in the individual load cases are specified in 8-23
l 5.4. Restraining structure The restraining structure (Figure 2.8) forms the anchor point of the relief system. Xt supports the outward-acting forces and moments especially during vent clearing, but, also during condensation. The load on the restraining structure is speci-fied and described in detail in /9/. 5.5. Protective tube The task of the protective tube surrounding the blowdown pipe inside the suppression chamber is to prevent the emergence of steam into the air space of the suppression chamber in the event of a leak and thereby to maintain the operation of the pressure suppression system. The operational loads and the load in the event of a leak in the blowdown pipe are specified and described in detail in /10/. The water in the annular gap between the blowdown pipe and the protective tube is heated when the relief system responds. The flashing rates into the drywell are very low. Expectation values are indicated in /l0/. lf it should turn out during the start-up measurements that undesirably high moisture rates emerge into the drywell from the gap, then this gap shall be sealed in the region of the suppression-chamber head in a pres-sure-tight manner with respect to a differential pressure of 0.2 bar by means of a leaktight membrane which breaks under a larger load. Through small openings in the protective tube, 8-24
a natural circulation could then be created between the hot water in the gap and the pool of the suppression chamber. 8-25
Discussion concernin the failure of individual com onents A failure of the valve is conceivable in the following form: - A valve jams and does not open. In this accident, the re-maining 6 valves can be used. A valve jams at first and then opens suddenly when full sys-tem pressure appears on the control pressure side. This perturbed opening behavior of the valve is taken care of by very small valve-opening times of only 100 ms, which are allowed for in the design of the system. Smaller opening times are not possible according to /8/. Furthermore, the GKM tests, in which a larger pressure is present on the con-trol pressure side than on the system side, demonstrate that the valve-opening time in the plant cannot be less than 100 ms. A failure of the safety/relief valves to close can be caused by a failure of the pilot valves (which are present in dupli-cate) to respond. Accident sequences which could be produced in this manner are excluded by a limitation of the pool water temperature, which produces a timely shutdown of the reactor. In order to prevent an impermissible amount of water from collecting at the valve seat and also in the control line, which delays the valve opening, the valve is drained and the control line is also provided with a specified drain hole. On the other hand, these intentional leakage points, which 8-26
also include the leakage via the piston rings, have such small dimensions that an impermissible amount of steam cannot flow out from the control side. Should the redundant snifter valves not close completely, then a leak is produced in the drywell. The quencher is so sized and made safe by production monitor-ing and inspection that a tearing-off of the perforated-pipe quencher or one of its arms can be ruled out. ln the event of a leak in the blowdown pipe, the protective tube prevents an emergence of steam into the air space of the suppression chamber. Xn so doing, the load reduction achieved by the quencher is maintained, since the protective tube and the blowdown pipe form a small annular gap only 10 mm wide in the water space of the suppression chamber. Otherwise, the protective tube represents a redundance of the blowdown pipe. Therefore, the same loads due to internal pres-sure and temperature have been specified for the protective tube as for the blowdown pipe. The torsional moment exerted on the quencher is transferred to the bottom mount through guide bolts. The bolts have a re-dundant construction. 8-27

Th'e dependence of the bottom loads during vent clearing on the clearing pressure in the pipe was studied. At a clearing pressuze above about 7 bar, the change of the positive pressure amplitude at the bottom with respect to the change of the clearing pressure yielded c = 0.0275, a value which practically coincides with the results in GKM. The pressure amplitudes at the bottom can be reproduced with an accuracy of
+0,15 bar (test series 2). Parameter study during vent clearing.
The relative size of the water pool has proved meaningful for the pressure values at the bottom. Because of the scale ratios of about 1 : 30 to 1 : 50, the absolute values measured in the test stand are not transposable to BWR plants.

]. Introduction Pressure oscillations which occur in a water pool when pipes partially filled with water are cleared generate noticeable loads on the bottom and lateral walls in the water space of the suppression chambers of boiling-water reactors. These loads arise from oscillations of the air flushed over into the water space when the safety/relief valves are actuated. In order to reduce the loads on the relevant structural components, pipe termination geometries were developed and tested in the test stand of the Mannheim Central Power Station (GKM). Disadvantages of this large-scale test stand are the low pressure of the available steam (20 bar) and the unalterability of the tank geometry (earlier condensate tank). In order to obtain more exact knowledge concerning the deter-minative parameters for the analyses of the transposition from the GKM test stand to the reactor, the condensation model test stand located in the Grosswelzheim nuclear-power experimental facility was connected to the high-pressure steam boiler of the test facility. The set-up and operation of the test stand are described in /1/. With this set-up it was possible to include the entire pressure range of interest, starting from the initial pressure, and its influence on the pressure build-up in the blowdown pipe and the loads on the bottom of the water pool. These relationships were 9-8
investigated primarily in the second test series. Additional tests served to prepare for large-scale tests in the GKM. Among other things, these were to clarify the influence of different dimensions of the water pool. It should be noted that, because of the too sharply differing ratios of the quantities involved, the test results are not transposable as absolute values to the plant. 9-9
- 2. Condensation model test stand 2.1.1 Basic set-up
~ ~ ~ ~ ~ 0 The set-up and dimensions of the test stand are shown in Figure 1. The model tank consists of a rectangular tank 3 m high, 1.6 m wide and 1.59 m deep, which is supported by a steel frame.
The tank is provided with glass discs on the front and back up to a height of 1.5 m in order to be able to also observe the vent clearing and condensation processes optimally. For safety reasons, the test stand is placed in a sheet-metal trough which can hold the water content of the tank if the glass discs should possibly break. Furthermore, the sheet-metal trough is shielded by movable positioning walls made of Plexiglas in order to protect persons and instruments from the outflowing hot water in the event, of a glass break. 2.1.2 Steam-boiler connection
~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~
The high-pressure boiler of the experimental facility was used as the steam generator. The steam output is 40 Mg/h, maximum pressure 165 bar and max.. superheated-steam temperature .520'C. Figure 2 shows the connection of the model test stand to the high-pressure boiler. Before beginning the test, the boiler is run up to the steam output and temperature desired later in the test. The generated steam is conducted from the main-steam line 9-10
via an exhaust-steam line into the condenser. The condenser is capable of absorbing the entire output of the boiler. The pres-sure in the condensation system (32 bar) is kept constant. During vent clearing and condensation tests, a pneumatically operated quick-opening valve is opened in the connection line to the boiler and two parallel-connected valves in the connection to the exhaust.-steam header are closed. At the end of the test, the valves are actuated in the opposite direction. These switching operations cause large changes in the flow rate in the condenser and thus large pressure oscilla-tions which cannot be compensated so quickly by the automatic pressure control. In order to prevent a response of the safety valves of the condenser, the steam flow rate therefore had to be limited to about 25 Mg/h in the tests. At higher pressures, the setting of the desired steam pressure at the quick-opening valve of the test stand is effected directly at the main-steam outlet. Then it is necessary to allow for an overpressure covering the piping losses. For required steam pressures of <30 bar, the steam is throttled from higher boiler-pressure by means of a manually operated valve in the connection line to the test stand. The desired steam condition, generally saturated steam, is ensured by monitoring the steam temperature. In order to avoid wet steam 'with certainty, the tests were always performed with minimally superheated steam. 9-11
2.1,.3 Adjustment
~ 0 ~ ~ ~
of steam flow rate g valve opening time
~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~
An exchangeable throttle nozzle was placed after the valve in order to set particular steam flow rates for different steam pressures before the valve. When the valve is opened, there results a flow rate which corresponds to the critical pressure drop across the valve at the beginning of the opening phase and to the critical pressure ratio across the quencher later. The full initial pressure across the quencher corresponding to the full flow rate is reached in a shorter time than the valve opening time. By measuring the pressure build-up before the throttle, a "fictitious valve-opening time" can be determined. Only for an initial fraction of the valve opening time does the increase of the flow rate not correspond to the flow rate through a valve operating in the critical pressure ratio. See Figure 20 for a clarification of this relation.

<o t fictitious The valve opening time affects the quantities being measured. As mentioned before, the steam is supplied through a "quick-opening membrane valve". The air connections for the pneumatic drive were substantially enlarged in comparison to the normal design
'n order to make possible shorter opening and closing times.
valve opening time was controlled by providing the preceding
'he electromagnet control valve with a manual control valve with which the air flowing from the membrane valve was regulated. It was thereby possible to vary the valve opening time in the range of about 150 - 900 ms.
2.2 Instrumentation An extensive outfitting of the test stand with measurement trans-ducers provided for a careful recording of static and dynamic pressures, temperatures, loads and steam flow rates. 1 9-13
P Most of the instrumentation was the same in all the tests described in this report. Deviations from the basic equipment. are mentioned in the individual test series. 2.2.1 Instrumentation t of the steam supply
~ ~ ~ ~ ~ 0 ~ ~ 0 ~ ~ ~ ~ ~ ~
To adjust the desired steam conditions, a number of measurement transducers for pressure and temperature were installed in the supply line between the main-steam line and the -test stand (see Figure 2, measuring points PFD, FP07-01, FT07-01). Between the quick-opening valve and test tank, additional measuring points were a'rranged in order to check the steam condition 'along the pipe. Especially important was the highly transient pressure and temperature variation during the valve opening. 2.2.2 Determination
~ ~ ~ ~ I ~ ~
of steam flow rate
~ ~ ~ ~ ~ ~ ~ ~ ~
In order to determine the amount. of steam introduced into the test facility, we used 3 methods which were differently well suited for different boundary conditions. a) A measuring orifice was installed in the connection between the main-steam line and quick-opening valve. The differential pres-sure occurring there was measured by a Barton cell. The mea-surement signal could be read off on a directly indicating instrument. Here we measured the steam flow which flowed before the beginning of the test in the exhaust-steam header and then the amount that flowed during the test to the blow-out geometry. 9-14
The steam flow rate in the steady-state can be determined quite exactly in long-term tests (condensation tests) by this measure-ment. This method is not suitable for vent clearing tests in which only the first few seconds of the test are of interest. But during this time the alternate closing and opening of the valves in the connection lines to the exhaust-steam header and to the test tank cause intense pressure fluctuations in the pipe. Of course, no reasonable measurement of the differential pressure across the orifice is then possible. b) The second method to determine the flow rate is made possible by the throttle nozzle between the quick-opening valve and the test tank. Since there is a supercritical pressure ratio across this nozzle under almost all existing conditions, the speed of sound is reached in the narrowest cross-section. Together with the nozzle cross-section and the pressure before the nozzle, the flow rate can be indicated exactly at any arbitrary time. Therefore, this method is especially well suited for recording the increasing steam flow rate through the opening valve during vent clearing tests. An inspection and calibration of the measurement, values is possible with the method described under c). Zn this regard, see also the dependence of the steam flow rate on the initial pressure for various throttle diameters as illus-trated in Figures 3 and 4. 9-15
c) The most exact method for determining the integral value of the supplied steam is to measure the water level in the test tank. In condensation tests with temperature increases of about 20 C to about 90 C, the water level rose by 200 to 250 mm. Thus, the measurement error is no larger than +1%. In long-term tests with constant steam mass flow, method c) can be used to check the accuracy of the first two methods, which are affected by a larger error because of their underlying principle. 2.2.3 Pressure transducers
~ ~ ~ ~ ~ ~ ~ ~ ~ ~
in the test stand
~ ~ ~ ~ 0 ~ ~ ~ ~
E A number of pressure transducers are mounted on the bottom and on one side of the tank in order to record the'ressure waves emanating from the pipe texmination geometry. In order to avoid effects caused by deformations of the tank, the bottom pressure transducers were inserted into a rigid guide sunk into the bottom of the tank. In order to be able to continue comparison studies begun earlier concerning the suitability of different types of pressure trans-ducers /1/, transducers having rear and external diaphragms and piezo-electric transducers were used. The lateral pressure transducers could be used at various heights on the side wall in order to make possible an adaptation to the particular test geometry. 9-16
Xn order to be able to check whether and to what extent tank oscillations are superimposed on the recorded pressure amplitudes, in most of the tests an additional pressure transducer, diaphragm transducer was mounted down from the ceiling of the hall without any connection to the test tank. The data transmitter was placed freely in the water space. The measurement values were recorded by a light-beam oscillograph (Visicorder). The feed of the recording paper was variable within H broad limits. For most of the vent clearing tests, the recording was made at I a paper speed of 1 m/s. The basic configuration of the measurement chain is sketched below.

2.2.4 Temperature transducers in the test stand
~ ~ ~ ~ ~ 0 ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~
In analogy to the pressure measurement points, thermocouple elements (NiCr-Ni) were built into the test tank for temperature measurement. During the vent clearing tests', which last only a few seconds, they were used primarily only to check the water temperatures before beginning the test. 2.2.5 Displacement transducers

For an exact measurement of the valve opening time, an inductive-type displacement transducer was mounted parallel to the valve spindle. This recorded not only the end points of the valve travel but also the behavior during the opening displacement. 2.2.6 Integral load on the test stand 0 ~ ~ 1 ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ i The test tank was mounted at its four support points on load cells (piezoelectric measurement principle) which in turn sat on the substructure. The sum signal from these transducers cor-responded to the total load on the test tank due to the pressure pulsations occurring in the water space during vent clearing. Beginning in test 275, the load cells were removed and the tank bottom was propped additionally in order to reduce its suscep-tibility to oscillation. 9-18
f Vent clearin tests in the model'est stand 3., The tests performed from Nay 1973 to January 1974 on the clearing of water-filled pipes are listed in Table 1, Sheets 1-4. This list provides the test date, assignment to a particular test series and valve opening time. In this Table, the indicated mass flow density m always relates to the outlet cross-section, of the termination geometry of the blowdown pipe. A geometric configura-tion (a perforated cross pipe) with two different outlet areas was used exclusively for the tests covered in this Report (see Figure 5). The individual outlet opening was always a hole having a diameter of 10 mm, corresponding to the stipulated reactor design. 3.1 Test series 1 Influence of tank geometry on the bottom pressure during vent clearing. 3.1.1 Test goal
~ 0 ~ ~
Observations in earlier tests revealed an influence of the dimen-sions of the water pool on the measured bottom pressures. In the following tests, this influence was to be examined more exactly in order to make certain about the transposition of the values measured in the GKM test stand to reactor conditions. In these tests, the pipe between the valve and model tank was heated. 3.1.2 Special test set-up

The set-up corresponds essentially to the general description in 9-19
Item 2. The measurement set-up is illustrated in Figure 6. The perforated cross pipe 1 with A = 31.4 cm was used as blow-out geometry. Pi e heatin The specific surface area of the pipe between the valve and out-let geometry relative to the reactor is larger by a factor o f 10 to 12 in the model test stand than in the reactor. In order to reduce the associated substantially higher condensation rate in the model test stand, an electrical heater was installed along the major portion of this pipe. It consists of a total of 5 heater bands of 1070 watts each. They are divided into 3 groups of 2 or 1 heater band each, and each group is controlled by its own thermostat. The associated temperature sensors were installed V between the pipe surface and heater band. 'or an adjusted nominal temperature of 200 C, the temperature of the pipe surface is kept constant to within approximately +5 C. Larger deviations were found at the ends of the heated section and at a few unheated flanges. Here the temperature before beginning the tests was about 100 C. Restriction of the water s ace The tank's influence was investigated by arranging a circular sheet-metal jacket from the bottom up to the water surface con-centrically around the blow-out geometry or using the model tank without. any restriction. Since the pipe heating ended about 1 m 9-20
above the water surface, an appreciable heating of the water and increase of the water-vapor partial pressure was avoided. The transposition parameter between the model test stand and GKM or the reactor was assumed to be the ratio of the water surface area to the cross-sectional area of the air bubble, assumed spherical, corresponding to the amount of air enclosed in the pipe. Zn one case, the GKM conditions were to be simulated in this way in the model test stand. Zn the model test stand, the preheating of the pipe to 120 C on the average must be allowed for when determining the air volume. The effective air volume's reduced correspondingly. 3.1.3 Test execution
~ ~ ~ ~ ~ ~ ~
Vent clearing tests were performed with 4 different dimensions of the water space. The ratios described above between the air volume and water surface area are shown in Table 4. The last two columns indicate which water surface area or which suppres-sion-chamber section in the reactor corresponds to the parti'cular experimental set-up. The tests were performed with a mass flow density of 1000 kg/m s and, in a few cases, also with 500 kg/m s. The setting was done by the initial pressure across the throttle nozzle (58 kg/cm [gauge] at 1000 kg/m 2 s). The submergence was 1000 mm and the distance from the bottom was 300 mm. Chosen as the representative bottom pressure was the measuring point P>4 (piezoelectric trans-ducer) which was located precisely under the quencher and which 9-21
always indicated the highest values. Zn the eccentric arrangement of the quencher, the shortest distance to the tank wall was tank'.1.4 Test results
~ ~ ~ ~ ~ ~
All the essential test data are compiled in Table -' Figure 7 shows the bottom pressure as a function of the valve opening time. The various curves make clear the influence of the tank dimensions. This trend becomes still more clear from Figure 8 where the bottom pressure was plotted for various valve opening times as a function of the free water-surface-area or the ratio of air/ bubble cross-sectional area to water-space cross-sectional area. For the unrestricted water space, it seemed appropriate here to use the cross-sectional area of an inscribed circle. Zf we compare the bottom pressures for A+A = 8.7 (GKM ratio) to those for A+A = 38.7, then we find a reduction of about 60% for the positive pressures and an even somewhat larger reduction for the negative values. The question as to which A+A ratio should be used for BWR cannot be answered here. The entire water surface area in EKB is approximately 440 m . The cross-sectional area of the air bubble expelled from one quencher is approximately 1.6 m . Figures 10, ll and 12 represent copies of the Visicorder traces with which the pressure values were obtained for three different 9-22
test set-ups. Except, for the water space, the boundary condi-tions were, the same in all three tests. The influence of the pipe preheating is clearly shown in Figure 9. Tests which were performed during the last series to examine the double pipe with the unheated pipe are compared here with similar tests with a heated pipe. Although no transposition factor can be read off here either, the influence of the pipe heating and
.of a more or less marked condensation can be seen.
3.2 Test series 2 Investigation of parameters during vent clearing. 3.2.1 Test goal
- 1. The pressure build-up in the pipe connection between a quick-opening valve (relief valve) and a pipe termination geometry arranged in the water space (perforated-pipe quencher) was to be investigated (vent clearing pressure).
- 2. The relation between the vent clearing pressure.and the loads occurring at the bottom of the test tank was to be determined experimentally. The vent clearing pressure was to vary at least in a ratio of 1:3.
3.2.2 Special test set-up
~ ~ ~ ~ ~ ~ ~ ~ ~
The set-up corresponds essentially to the description under Item 2. In order to guarantee the comparability of the model 9-23
tests with the GKM tests, a number of transposition parameters were to be considered. The corresponding data are compiled in Table 4 and Figure 14. The tests were always performed with an insert of the same diameter to restrict the water surface area. The steam was supplied via a quick-opening valve with a succeed-ing exchangeable throttle-nozzle. This throttle unit was con-nected closer to the test tank. The pipe section, which was shorter than in the earlier test series, could thereby be con-structed with a larger diameter. By this measure and the elec-trical auxiliary heating of the pipe also used here, greater condensation was prevented in this pipe. A In the part lying under water, the corresponding effect was achieved by means of an internal Hostaflon lining which was led as far as the stop of the perforated cross pipe. In order to obtain the same resistance coefficients, the diameter of the individual holes is the same as the hole diameter for GKN and reactor quencher (see Figure 5) . It should he noted that in com-parison to the preceding test series the outlet cross-sectional area A for the perforated cross pipe 2 used here is only half as large as for perforated cross pipe 1. To measure the velocity of the air/water phase boundary surface during the water expul-sion process, electrical resistance measurements were made at 5 points (Zl to Z5) (see Figure 13). 3.2.3 Test execution
~ ~ ~ ~ ~ ~ ~
In accordance with the test goal, a largest possible range of 9-24
vent clearing pressure was to be covered. For that purpose, the pressure before the valve was varied between 10 and 100 bar. The variation of the pressure before the throttle nozzle as a direct measure of the flow rate was 10 to 76 bar. Zn order to extend the range of the clearing pressures set in this manner, two test series were performed with a different diameter of the throttle nozzle.. The resulting mass flow density for the entire range covered was 220 to 2600 kg/m 2 s relative to the outlet cross-section of the perforated cross pipe. The submergence was 2.0 m in all tests. The valve opening time was adjusted to the smallest possible value. Zt was 145 ms
+ 15 ms on the average. The test duration was about 3 s in each instance.
The sheet-metal insert was led beyond the water level in order to decouple the internal and external spaces. 3.2.4 Test results
~ ~ ~ ~ ~
The most important data from the test evaluation, indicating the relationship between vent clearing pressure and bottom load, are compiled in Table 5. The measurement point P>4, which was located
,centrally under the outlet geometry, was used exclusively for the indication of the maximum bottom pressure. This measurement point also indicated the highest values in all cases.
The variation of the maximum clearing pressure (hPD< ) is illustrated in Figure 15 as a function of the initial pressure 9-25
before the throttle nozzle and thus as a function of the inflow-ing steam rate. In addition, the pressure value set at the mea-surement point PRl at the same time was also indicated. Basic-ally, the same dependence is shown in Figure 16, except that here the clearing pressure is illustrated as a function of the mass flow density relative to the pipe and outlet cross-section. The most important result from these tests, the relation between clearing pressure and bottom load, is evident from Figure 17. From the mean-value curve, a dependence of the change of the positive pressure amplitude at the bottom relative to the vent clearing pressure can be indicated in the form 8 = hPB hPDE
= 0.0275 in the upper range. If we extrapolate beyond the measurement range, this value seems to decrease further. A quantitative indication concerning the further decrease of c is not possible.
For the positive pressure amplitudes, the range of double stan-dard deviation was also plotted. The reason for the larger scatter in the range hPDE DE max
= 8 bar compared to the other values surely lies in the fact that at this point there is a crossover of two measurement series with different prethrottling.
The highly variable initial pressure has effects which cannot be evaluated exactly and are responsible for the larger devia-tions from the mean value. In general, however, it can be stated that the pressure values at the bottom could be 9-26
reproduced with an accuracy of +0.15 bar. A statistical evaluation of the scatter was dispensed with for the negative pressure amplitudes at the bottom, because only slight deviations from the mean value occur, especially at the higher values. The curve leads us to conclude that there is an asymptotic approach to the value -0.5 bar. The measurements concerning the speed of the water surface-pass-ing thxough the pipe during the vent clearing are evaluated in Figures 18 to 21. The path-dependent change of the speed is il-lustrated for various clearing pressures in Figures 18 and 19. In Figures 20 and 21, the speed is illustrated as a function of the time after the valve opening begins. Copies of the Visicorder recordings together with the measured pressure values are included in Figures 22 to 25 for 4 tests. The particularly interesting curves for FP07-04, dP and hP 4 are specially emphasized. The measurement-point coverage of the light-beam oscillographs used for this test series (Visi-corder) is shown in >>Table 7 and Table 8. The frequency of the first air-water oscillation was 5.4 to 5.9 Hz in all tests. These relatively slight differences are caused by slightly different boundary conditions (temperature and moisture content of the air in the pipe before the test). The different clearing pressures quite obviously have no influences on the frequency. 9-27
- 4. Summar o f results The vent clearing tests in the condensation model test stand in Grosswelzheim have demonstrated the direct relation between the pressure build-up in the pipe and the dynamic pressure loads on the bottom of the confining tank. The clearing pressures in the pipe vary within a range of 3 to 18 bar.
Important observations concerned the influence on the bottom pressures exerted by the water space relative to the amount of air introduced during the clearing. By parametrizing the cross-sectional area of the water space, it was possible to obtain from these tests important information for the transposition of the quantitative results obtained in GEM tests to reactor conditions. The influence of the stiffness of the surrounding tank walls on the wall load and bottom load was determined qualitatively. A "compliant" confining wall, which was loaded up to or beyond the permissible limit, resulted in values up to 60% lower than a "noncompliant" wall. No quantitative statement can be made about this dependence. For all of the measured bottom pressures, it should be noted that no absolute values are transposable to reactor conditions. 9-28
