R1 vision 0 Abstract The LaSalle main steam tunnel (MST) leak detection system consists of temperature sensors that monitor the MST temperature and the ventilation system supply and exhaust air temperatures. The system functions to isolate the main steam line whenever abnormal conditions exist as indicated by high MST temperature or high differential temperature between ventilation system supply and exhaust air. The trip settings are established based on the temperature response of the MST due to steam leakage. This calculation uses a GOTHIC system model to determine the MST temperature response due to a variety of leak rates and supply air temperatures. The results are intended to be used to determine the appropriate setpoints in conjunction l

with other design considerations, such as allowable leakage rate and instrument uncertainties, which are addressed in other design calculations.

1. Introduction The main steam tunnel leak detection system is a part of the reactor coolant pressure boundary (RCPB) leakage detection system. Its design basis satisfies the requirements of 10CFR50 Appendix A General Design Criteria 54. One of the safety design bases given in Section 7.6.2.1.1 of the LaSalle UFSAR is " signals are provided to permit isolation of abnormalleakage before the results of this leakage become unacceptable."

This basis can be achieved through monitoring of the MST temperature and the trip logic used to isolate the steamlino whenever abnormal leakage exists. Trip setpoints must be set high enough to avoid spurious trip under normal operating conditions and low enough to provide early detection of abnormal leakage.

The purpose of this calculation is to determine the temperature response of the main steam tunnel (MST) due to different amounts of steam leakage for different supply air temperatures. The temperature response can then be used to specify a setpoint for leak detection.

2. Methodology /Model Description and Assumptions The main steam tunnel temperature response was calculated by a GOTHIC system model. The following sections describe the tunnel configuration, the transient due to a steam leak, the analytical model, the computer code, and the input parameters and assumptions used in the analysis.

2.1 PhysicalConfiguration

~

A sketch of the MST is shown in Figure 1. In this analysis, the MST is subdivided into three areas denoted as the lower, middle and upper MST. The lower and upper MST extend from Elevation 687 to 706 ft and from Elevation 736 ft 7 in to 768 ft 4.5 in, respectively. The middle MST consists of th? vertical section of the tunnel between Elevation 706 ft and 736 ft 7 in.

The temperature of the MST is maintained by the reactor building ventilation (VR) system. Two streams of VR air enter the MST at different elevations and exit the tunnel via an exhaust riser located at the top of the MST. Air from the area between the primary containment and core standby cooling system (CSCS) cubicles enters the lower MST at the floor level (A). The air inlet at A is configured to yield a high velocity stream capable of sweeping the lower MST regions. In the current plant configuration, there l are two exhaust vents at B. The majority of the air introduced at A sweeps toward B I

. and then reverses direction, flowing to the upper regions. After flowing through the '

middle MST and the upper MST, the air exits the tunnel via the exhaust riser (D). The '

other air stream, which comes from the refueling floor and the reactor water cleanup (RWCU) area, enters the upper MST at (E) and exhaust through the exhaust riser (D).

This analysis is based on a revised configuration without the exhaust flow path at B, except for the heat load calculation which is based on data for the current configuration.

2.2 Description of Transient The analysis assumes continuous steam leakage from cracks in the main steam line.

The cracks are postulated to occur at any location along the fulllength of the steamline inside the MST. In the event of steam leakage with VR in operation, the temperature at locations downstream of the crack will experience a temperature rise, while locations upstream of the crack may not experience (except locally) any temperature increase at all. For example, cracks in the upper MST will not result in temperature rise in the lower MST. Hence, for leak detection purposes, a sensor located near the exhaust riser in the upper MST is capable of detecting leaks that occur anywhere in the MST. For a given amount of leakage, the temperature rise is greatest near the vicinity of the crack and decreases as the distance between the crack and the location of interest increases.

Therefore, the basis for the leak detection setpoint for a sensor located in the upper

MST is leakage from a crack located in the lower MST near the area where the steam lines exit the tunnel. Thus, in this analysis, only a leak in the lower MST is considered 2 of 19

BSA L-95-oS R; vision 0 i

j for the purpose of establishing a leak detection setpoint. However, upper MST leaks l

are also considered to confirm that the lower MST leak location is bounding.

2.3 Analytical Model The temperature response of the MST due to steam leakage is calculated by considering the mass and energy balances for the MST. A schematic of these quantities is shown in Figure 2. A GOTHIC system model is constructed based on this schematic, it consists of three control volumes representing the upper, middle and lower MST. Five additional control volumes are used to model the structures adjacent to the MST. A flow path is used to represent the flow from the lower to the middle MST and another path from the middle to the upper MST. Three additional flow paths are used to model the VR inlet and exhaust flows. Heat transfer through the walls, ceilings a.1d floors to the adjacent structures is modeled with 16 heat structures. The heat load in the MST is produced predominantly from ti:e main steam and feedwater lines and is represented by one heater located in each of the control volumes. Additional model features and assumptions are listed in Section 2.5.

l 2.4 Computer Code The GOTHIC (Reference 1) computer code is used in the analysis. This code was

! developed by Numerical Applications, incorporated for the Electric Power Research Institute (EPRI). GOTHIC is a general purpose thermal-hydraulics computer program for design, licensing, safety and operating analysis of nuclear power plant containments l

and other confinement buildings. Applications of GOTHlO include evaluation of l containment and containment sub compartment response to the full spectrum of high energy line breaks within the design basis envelope. Applications may include pressure l and temperature determination, equipment qualification profiles and inadvertent system initiation, and degradation and failure of engineered safety features.

l The code was verified and validated by Comed and was installed in the company l !

computer system in accordance with approved Company procedures and requirements

! for design application computer codes (Reference 2).

l l 2.5 Input Assumptions and Parameters l

As described in Section 2.2, the basis for establishing a leak detection setpoint is the lowest temperature rise in the MST. Therefore, the input assumptions and parameters are chosen conservatively to yleid a low estimate of the temperature rise due to steam leakage. The following input assumptions and parameters were used in the analysis:

1. The heat transfer area of the walls, ceiling and floors were conservatively calculated without taking any allowances for obstructions. This assumption maximizes the heat

. i transfer out of the MST. Likewise, the gross volume of the MST is used.

r i

CSA L-95-05 Rivi: ion 0 Calculations for heat transfer areas, volumes and other geometrical parameters are given in Appendix C.

2. The mechanism of heat transfer between air and the heat structures is specified to be either convection plus radiation or condensation. The Uchida correlation is used to calculate the condensation heat transfer coefficient.

3. The thermal conductivity, density and specific heat of the reinforced concrete walls are taken as 0.92 Btu /hr-ft-F,145 lb/cu ft and 0.156 Btu /lb-F, respectively, based on Reference 3.

4. The temperatures of the VR supply air into the upper and lower MST are assumed to be equal. The VR supply air originates from outside the plant and enters the MST after passing through various areas in the reactor building. Hence, the VR supply air temperature is dependent on the outdoor air temperature. Two different supply air temperature values,65 and 110 deg F, are used to bound the conditions expected year-round. Another temperature wlue,95 deg F,is used which represents a typical condition expected during a moderately hot summer day. The relative humidity of the VR inlet air corresponding to the assumed temperatures are:

Temperature, F Relative Humidity, %

65 30 95 50 110 30 The temperatures of the upper and lower MST supply air may be different. Plant data indicates that the lower MST supply air temperature may be 6 to 7 deg F warmer, it is conservative to assume the upper and lower MST supply air temperatures to be equal because it results in a lower temperature rise in the upper MST.

5. The assumed conditions for the adjacent volumes corresponding to the assumed VR supply air temperatures, are:

VR supply air temperature, deg F 65 95 110 Auxiliary Building 65 104 110 Auxiliary Building (conditioned space) 75 75 75 Reactor Building 65 95 110 Containment 130 130 130 The assumed conditions provide the boundary conditions for the problem. They are also used by the code to calculate the initial temperature profiles in the heat structures. They have only a secondary effect on the through-wall heat transfer to the outside due to the thickness of the concrete and its low thermal diffusivity. The tunnel temperature response is quick and reaches steady state in a short period of 4 of 19

time. Only a fraction of the wall thickness experiences an appreciable change from ,

the initial conditions, !

6. The VR flows are induced by the VR system exhaust fans. The upper MST exhaust flow, which consists of ventilation air and steam, is assumed to be at a i constant volumetric flow rate. The VR flow rates used in the analysis are based I on plant data and they are: !

Upper MST supply air (initial condition) 24,000 cfm Lower MST supply air (initial condition) 40,000 cfm Upper MST exhaust air 64,000 cfm The flow rates are based on a temperature of 95 deg F.

Because the VR flows are induced by the VR exhaust fans, tha inlet VR flows are reduced by the presence of steam. The reduced inlet flow phenomenon may affect the temperature indication from a sensor located in the VR inlet. As the inlet flow l

reduces to zero due to increased leakage flow, the temperature indicated will be that of the MST instead of the inlet flow. The analysis takes into account the effects of reduced flow phenomenon as follows:

a. Analyses were performed by assuming only the lower VR inlet flow is reduced. '

, With no reduction in upper MST VR inlet flow, a conservative upper MST temperature will be calculated for leaks in the lower MST. These results form the l bases for the analytical values for setpoint determination.

b. Confirmatory analyses were performed to determine that the bases are bounding by allowing both the upper and lower MST inlet flows to vary according to the thermodynamic conditions in the MST. These analyses consider steam leaks in both upper and lower MST.

7. The heat load for each of the three volumes in the MST is calculated using the GOTHIC analytical model of the MST using the following input:

Lower MST supply air flowrate 40,000 cfm Lower MST supply air temperature 95 deg F l Lower MST supply air relative humidity 50 %

! Lower MST temperature 110 deg F l Lower MST exhaust air (through duct) flowrate 4,600 cfm Middle MST temperature 114 deg F Upper MST supply air flowrate 24,000 cfm Upper MST supply air temperature 95 deg F Upper MST supply air relative humidity 50 %

Upper MST temperature 124.6 deg F 5 of 19

BSA-L-95 05 Rivision 0 The calculated heat load is valid at the ambient temperature resulting from the above input conditions. It is multiplied by a normalized heat load vs. temperature curve to yield the heat load for a different tunnel temperature. Because the heat load in the MST is produced predominantly by the main steam and feedwater lines, the normalized curve is assumed to have the form:

O/Qo = U/Ua x (T- Tam)/(To- Tnm) I where U is the overall heat transfer coefficient of an insulated pipe and it is a function of temperature. Details of the heat load calculations are given in Appendix C.

~ 8 The amount of steam leakage is expressed in gpm By definition the mass flow rate of onc gpm of steam leakage is equal in numerical value to the mass flow rate of one gpm of water with a density of 62.4 lb/cu ft. For example, 1 gpm of steam leakage = 1 gpm x 62.4 lb/cu ft /7.48 gal /cu ft = 8.34 lb/ min of steam l

9. During normal plant operating conditions, the steam pressure at the throttle valve is 965 psia (Table 10.1-1, UFSAR) and the steam dome pressure is limited by Tech Spec to less than 1020 psig (Tech Spec Sec. 3.4.6.2). Over this range of pressure, the enthalpy of saturated steam varies inversely with pressure. For this analysis, it is conservative to assume a low enthalpy value. Therefore, the condition of steam is assumed to be saturated at 1050 psia with an enthalpy of 1189.9 Btu /lbm.

10.The leak is located in the lower MST. As discussed in Section 2.2, this location gives the most conservative temperature setpoint.

11.A linear 100 sec leakage development profile is used in the analysis. The temperature response is expected to be quick and a near steady state condition is expected to be reached in a short period of time. Hence, the temperature results are not affected by the assumed profile shape.

3. Model Benchmark l

The validity of the analytical model is established by comparing the GOTHIC model results with plant measured data. Figure 3 shows the results of the calculated upper MST temperature during normal operation at different VR inlet temperatures. The plant measured data taken in the period from October 8,1995 to November 20,1995 are also plotted in the same Figure for comparison. The plot shows very good agreement

4. Results Figure 4 shows the upper MST temperature response as a result of 100 gpm of steam leakage. The VR inlet temperature is 110 deg F and the leak is initiated at time equal to 1000 sec. The temperature increased 45.1 degrees from 137.4 to 182.5 deg F in the first 10 minutes but added only 1.1 degrees in the next 30 minutes. The quick ,

temperature response is typical for all the cases analyzed. The quick response assures J that a leak of sufficient quantity produces a sufficient temperature rise which can be detected in a timely fashion.

Figure 5 shows the upper MST temperature for different leakage rates and for different !

VR inlet temperatures. These are the temperatures at approximately 10 minutes after !

the leak. In most cases, the temperature has reached a steady state value, and if it has !

not, it is very close to the steady state value. The results show that the temperature i varies directly with the quantity of steam leakage. For a given leakage rate, the upper MST temperature is highest for a VR inlet temperature of 110 deg F and lowest for a VR inlet temperature of 65 deg F.

Figure 6 shows the temperature difference between the upper MST exhaust and supply air (VR Delta T). These are the Delta T's at approximately 10 minutes after the leak. In most cases, the Delta T has reached a steady state value, and if it has not, it is very close to the steady state value. The results show that the Delta T varies directly with the quantity of steam leakage. For a given leakage rate, the upper MST Delta T is highest for a VR inlet temperature of 65 deg F and lowest for a VR inlet temperature of 110 deg F.

5. Conclusions / Discussion l l

There are two basic requirements needed in choosing a process variable to monitor for l

leak detection. First, the response of this variable should be quick so that the leak can be detected in a reasonable time. Second, the change in magnitude of this variable to a given amount of leakage should be ample enough to account for measurement uncertainties and to avoid spurious trips when no leakage is present. The results presented in Section 3 show that in looking at each VR inlet condition separately, the upper MST temperature and upper MST VR delta-T satisfy these two requirements.

Therefore, a high temperature and a high delta-T trip setpoint can be set for each of the l VR inlet condition. However, a single trip setpoint that is valid for all VR inlet conditions l b desired. This Section discusses how a leak detection trip setpoint can be established for use year-round. It also shows that under some conditions, it is not possible to establish a year-round setpoint. An example is given to show that the high tempmature trip setpoint can not be established to detect a leak of 100 gpm. ;

l The first step in determining the trip setpoint is to establish the allowable leakage. This is determined from the critical crack flow, which is the leakage rate from a crack whose dimensions are calculated to rapidly propagate and result in pipe failure. Therefore, the allowable leakage is obtained by applying a design safety factor to the critical crack flow. The determination of the allowable leakage is not within the scope of this calculation.

If one assumes that the allowable leak rate has been determined to be 100 gpm, and the instmment uncertainties are +63 and -62, a proposed setpoint value can be established by using the analytical results as follows:

Setpoint s Analytical value for 100 gpm leak - 62 To avoid spurious trips, the proposed setpoint must have ample margin from the maximum expected temperature with no leakage during normal or no VR operation.

Therefore:

Setpoint 2 Analytical value for no leak + Si l

The right hand side of both inequalities may contain other margins and uncertainties due to operational transients such as loss of strtion heat or changes in outside air temperature, but for this discussion it is sufficient to include them in Si and 62 Therefore, the setpoint will be adequate if the difference between the analytical values for 100 gpm and no leak, the analytical margin, is greater than the sum of the measurement uncertainties:

Analytical margin 2 Si+ 62 l 9 of 19

CSA-L-9545 Rxvision 0 From Figure 5, the upper MST temperatures at 10 minutes for a 100 gpm leak are 151.3,173.5 and 182.5 deg F respectively for VR inlet temperatures of 65,95 and 110 deg F. If one setpoint value is used to cover the whole range of expected VR inlet temperature conditions, then the lowest calculated temperature for 100 gpm leak must be higher than the highest temperature for no leak. The analytical temperature value I

for 100 gpm leak is 151.3 deg F which is less than the temperature experienced in the MST when the VR system is out of service. Therefore, the single year-round high temperature setpoint can not be established based on an allowable leakage of 100 gpm.

From Figure 6, the upper MST VR delta-T's at 10 minutes for a 100 gpm leak are 86.3, 78.5 and 72.5 deg F respectively for VR inlet temperatures of 65,95 and 110 deg F.

Corresponding to these VR inlet temperatures, the delta-T's for no leak condition are 28.2,27.9 and 27.3 deg F. If one setpoint value is used to cover the whole range of expected VR inlet temperature conditions, then the lowest calculated delta-T for 100 l gpm leak and the highest calculated delta-T for no leak should be used in its detemilnation. This would result in an available margin of 72.5 - 28.2 = 44.3 degrees. l The available margin is also sufficient to cover the delta-T experienced in the MST when the VR system is out of service. The delta-T has been observed as high as 46 deg F, The calculated upper MST temperatures are higher when both the upper and lower VR inlet flows are varied according to MST conditions for both upper and lower MST steam leaks. Both upper and lower VR flows are reduced to zero for a 250 gpm leak. The '

results of the calculations show that the analytical value of 72.5 deg F for a 100 gpm leak is conservative l
