SUBJECT:

Turbine Building Temperature Response to Steam Leaks BV1 BV2 DB PY ORIGINATOR/DATE REVIEWER/DATE DESIGN VERIFIER/DATE APPROVER/DATE James E. Praser David J. Godshalk Tom O'Reilly OBJECTIVE OR PURPOSE OF ADDENDUM:

This addendum contains two parts. The purpose of Part 1 to this Addendum is to evaluate the temperature response in the Turbine Building to a new limiting Main Steam leak of 32.90 Lbm/sec. This evaluation is performed in line with the objective of Calculation 2.4.6.14. Conclusions will be based on whether the results meet the specified acceptance criteria in order that boundary dose limits are not exceeded.

The purpose of Part 2 to this Addendum is to evaluate the temperature response in the Turbine Building to a Main Steam leak after two temporary fans, each with a flowrate of 1000 cfm, have been installed to circulate air in the vicinity of temperature switches 1E31N0361A/B/C/D. This information will be compared to the results of PNPP Calculation 2.4.6.14 Rev. 0, as well as Part 1 of this Addendum, and will aid in evaluating the ability of this interim measure to eliminate the possibility of nuisance trips of the Turbine Building temperature switches (1E31N0361A/B/C/D) that trigger MSIV isolation.

SCOPE OF ADDENDUM:

The scope of Part 1 to this Addendum falls in line with the scope of Calculation 2.4.6.14. The only change made to the base analytical models was the mass flow rate of the leak.

st The calculation results from Part 2 to this Addendum apply to operation of the fans during the summer months (June 1 -

st October 1 ). The addition of the fans in the Turbine Building is a temporary modification that will be removed during RF10 (April, 2005).

SUMMARY

OF RESULTS/CONCLUSIONS OF ADDENDUM:

Part 1 The analysis indicates that a steam leak rate of 32.90 Lbm/sec will result in elevated temperatures of 145°F and 160°F near the E31 thermocouples well within the acceptable time limit of 1 hr 11 min 46 sec.

Part 2 Comparing the results of the GOTHIC model, before and after the addition of the fans, reveals minor yet generally consistent effects. Beyond the special case of Summer Leak Location #1 (discussed further in the Conclusions section), the results are consistent in predicting that the fans will help to homogenize the volumes and decrease the time for detection. Even in the instance that the time required is increased, all of the detection times still remain well within the acceptance criteria.

SUBJECT:

Turbine Building Temperature Response to Steam Leaks This Addendum was prepared in accordance with the methodology of Calculation 2.4.6.14. Therefore, review of this Addendum shall be done in association with Calculation 2.4.6.14.

Analysis Methodology Part 1 The purpose of this part of the addendum is simply to provide additional Turbine Building temperature response data for the new limiting leak rate of 32.90 Lbm/sec established in Calculation 2.4.6.15 Rev. 0 (DIN 3). Therefore, the analysis methodology used in Calculation 2.4.6.14 remains the same with the only difference being the leak flow rate (Boundary Condition 2F). Evaluations will also be performed, and subsequent results represented, in a manner consistent with the original calculation (Summer, Winter, and Average conditions at Leak Locations 1, 2, 3 for a total of nine (9) new scenarios).

Part 2 This part of the addendum evaluates the Turbine Building temperature response, after two (2) temporary fans have been installed to circulate air in the vicinity of temperature switches 1E31N0361A/B/C/D, using the GOTHIC computer code (Version 7.0) (DIN 1). Referring to the base calculation as well as Part 1 of this Addendum, the fans were added to the GOTHIC models that predict the highest and fastest temperature rise at the location of the thermocouples at the East end of the Turbine Building. The highest leak rate under Summer Conditions fits this criteria. However, the highest leak rate of 45.11 Lbm/sec was not selected, because according to Calculation 2.4.6.15 Rev. 0 the limiting leak rate due to critical crack length is 32.90 Lbm/sec. Therefore, the applicable worst-case scenarios being analyzed for this part of the addendum are the following:

  • Summer Conditions, Leak Location #1, 32.90 Lbm/sec
  • Summer Conditions, Leak Location #2, 32.90 Lbm/sec
  • Summer Conditions, Leak Location #3, 32.90 Lbm/sec The basis and methodology of these original GOTHIC models is described thoroughly in PNPP Calculation 2.4.6.14 Rev. 0, as well as Part 1 to this Addendum.

In addition to the above three (3) scenarios, additional GOTHIC models were run under identical conditions (Summer Conditions, Leak Locations 1, 2, and 3) but with a leak rate of 19.68 Lbm/sec. The purpose for analyzing these specific scenarios is two-fold. First, the analysis will provide sensitivity data on the effect of the fans as the leak rate decreases. Second, a leak rate of 19.68 Lbm/sec meets the 10CFR100 site boundary dose limit criteria set forth in the base calculation that the total mass effluent from the steam line leak shall not exceed the total mass release from the main steam line break (141,687 Lbm) within two hours.

Each evaluation will determine the time required to reach 145°F and 160°F at the location of temperature sensors 1E31N0361A/B/C/D. These results will be compared to those predicted in the absence of the two temporary fans. The E31 leak detection thermocouples are located on the East wall at column TB14, approximate Elevation 632-feet (GOTHIC sub-volume V7s15).

SUBJECT:

Turbine Building Temperature Response to Steam Leaks A code-generated diagram in Attachment A indicates the basic layout of the Turbine Building GOTHIC model, showing the control volumes, the boundary conditions, the interconnecting flow paths, and the volumetric fans.

The GOTHIC model for this calculation analyzes the addition of two fans each blowing air at 1000 cfm through a hydraulic line. Each hydraulic line takes suction from the East end of the Turbine Building at Elevation 602 ft (GOTHIC sub-volume V7s9) and discharges air at the East end of the Turbine Building at Elevation 621 ft (GOTHIC sub-volume V7s15) up towards the E31 thermocouples (DIN 2). Refer to Attachment B for a sketch of the fan locations.

Control Volumes Refer to the base calculation for information on how the Control Volumes were set up in the GOTHIC models. No changes were made to the control volumes for this addendum to the calculation.

Thermal Conductors Refer to the base calculation for information on how thermal conductors were set up in the GOTHIC models. No changes were made to the thermal conductors for this addendum to the calculation.

Flow Paths (Junctions)

Refer to the base calculation for information on how the Flow Paths were set up in the GOTHIC models. The following additions were made for this addendum to the calculation:

Flow Paths 38 and 39 were added to represent the two hydraulic lines used to discharge air from the fans up towards the E31 thermocouples. Both flow paths connect sub-volume V7s9 to sub-volume V7s15. Suction is taken at Elevation 602 ft, and discharge is located at Elevation 621 ft. The hydraulic diameter is set equal to the 8-inch diameter of the round flex duct (DIN 2), and the corresponding flow cross-sectional area is set at .35 ft2.

' Diameter 2 Area = = .35 ft 2 4

The inertia length of a GOTHIC flow path is the center-to-center distance between the connected volumes. For this application, since the flow velocities are relatively small for volume-to-volume flow, the flow path inertia length is approximated at 1 foot for each volume-to-volume connection. The flow path friction length is considered non-critical for this application and is set to 1 foot for all flow paths.

The flow path friction length only becomes important when the model is concerned with buoyancy and thermally-induced flow. In this case, air movement is driven by forced convection (i.e. the fans).

SUBJECT:

Turbine Building Temperature Response to Steam Leaks Components Two volumetric fans were added to the model, representing the temporary vane-axial ventilator fans being installed in the Turbine Building (DIN 2). One volumetric fan was placed on Flow Path 38, and the other was placed on Flow Path 39. They are both set to blow air at 1000 cfm (DIN 2), discharging just below the E31 thermocouples (sub-volume V7s15). Note that according to DIN 2, the estimated flow of 1000 cfm for each fan takes into account losses through the flex duct and grating.

Boundary Conditions Refer to the base calculation for information on how the boundary conditions were set up in the GOTHIC models. Boundary Condition #2F is adjusted for each scenario in order to model the desired leak rate.

Initial Conditions Refer to the base calculation for information on how the initial conditions were set up in the GOTHIC models. No changes were made to the initial conditions for this addendum to the calculation.

Turbine Building Thermal Characteristics Refer to the base calculation for information on how the thermal characteristics were determined for the GOTHIC models. No changes were made to the Turbine Building thermal characteristics for this addendum to the calculation.

Turbine Building Temperature Response to Steam Leaks Assumptions Parts 1 and 2

1. All assumptions stated in PNPP Calculation 2.4.6.14 Rev. 0 apply to this calculation.
2. All other assumptions are stated within the calculation.

Acceptance Criteria Parts 1 and 2 The temperature in the Turbine Building due to the 32.90 Lbm/sec steam leak must reach the particular analytical limit (145°F or 160°F) in less than 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> 11 minutes 46 seconds.

The temperature in the Turbine Building due to the 19.68 Lbm/sec steam leak must reach the particular analytical limit (145°F or 160°F) in less than 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> 59 minutes 59 seconds (2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />).

Basis: The total mass effluent from the steam line leak shall not exceed the total mass release from the main steam line break (141,687 Lbm). A leak rate that satisfies this criterion would ensure that the 10CFR100 site boundary dose limit is not exceeded.

Computation Parts 1 and 2 The thermal response over a 24-hour period at the location of the temperature sensors and at the steam leak is calculated by the GOTHIC computer program. For calculation brevity, only one input deck is included in Attachment C representing the Summer - Leak #1 - 32.90 Lbm/sec case. The required changes for all other cases are noted in the attachment. For further information on how GOTHIC performs its analysis, refer to the GOTHIC Users Manual (DIN 1).

SUBJECT:

Turbine Building Temperature Response to Steam Leaks Results Part 1 The resultant temperature graphs predict the temperature of the sub-volume that contains the E31 leak detection thermocouples (located on the east wall at TB14, approximate Elevation 632-feet, GOTHIC sub-volume V7s151). Also shown is the sub-volume temperature at the leak location2 if the leak location lies in a sub-volume different from the thermocouple sub-volume. The results over a 24-hour period for all cases are displayed below. A 24-hr period was analyzed in order to assure that steady-state temperatures were reached (the graphs confirm that this occurred). The following three summary items are listed below each graph.

  • The maximum temperature realized at the location of the thermocouples, along with the time required to reach the maximum temperature.
  • The time required to reach 145°F at the thermocouples.
  • The time required to reach 160°F at the thermocouples.

A summary of the times required to reach 145°F and 160°F can be found in Tables 1 and 2, respectively, at the end of this section.3 Attachment D contains the output data from which the results were derived. Note that the data produced by GOTHIC covers the time period from t = 0 seconds to t = 90,000 seconds (25 hours2.893519e-4 days <br />0.00694 hours <br />4.133598e-5 weeks <br />9.5125e-6 months <br />). As mentioned in Calculation 2.4.6.14, the steam leak is delayed to t = 3600 seconds (1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />) in order to allow the transient to steady. Therefore, times reported in the following results equal the output data minus 3600 seconds.

1 The legend in the GOTHIC-produced graphs denote sub-volume names with a T in front (e.g. TV7s15 is the same as V7s15).

2 Leak Locations 1, 2, and 3 lie in sub-volumes V7s15, V7s11, and V7s12, respectively.

3 o o Data points created by the GOTHIC analysis typically did not occur exactly at 145 F or 160 F. Consistent with Calculation 2.4.6.14, the data point was chosen that occurred at a time with a realized temperature closest to, but not less than, the target temperature (usually within a few tenths of a degree).

SUBJECT:

Turbine Building Temperature Response to Steam Leaks Part 2 The resultant temperature graphs indicate the temperature of the sub-volume that contains the E31 leak detection thermocouples (located on the east wall at TB14, approximate Elevation 632-feet, GOTHIC sub-volume V7s154). Also shown is the sub-volume temperature at the leak location5 if the leak location lies in a sub-volume different from the thermocouple sub-volume. The results over a 24-hour period for all cases (plus each corresponding case without the fan modification) are displayed below. A 24-hr period was analyzed in order to assure that steady-state temperatures were reached (the graphs confirm that this occurred). The following three summary items are listed below each graph.

  • The maximum temperature realized at the location of the thermocouples, along with the time required to reach the maximum temperature.
  • The time required to reach 145°F at the thermocouples.
  • The time required to reach 160°F at the thermocouples.

A summary of the times required to reach 145°F and 160°F can be found in Tables 3 and 4, respectively, at the end of this section.6 Note that the output data produced by GOTHIC covers the time period from t = 0 seconds to t = 90,000 seconds (25 hours2.893519e-4 days <br />0.00694 hours <br />4.133598e-5 weeks <br />9.5125e-6 months <br />). As done in Calculation 2.4.6.14 and Part 1 of this Addendum, the steam leak is delayed to t = 3600 seconds (1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />) in order to allow the transient to steady. Therefore, times reported in the following results equal the output data minus 3600 seconds.

4 The legend in the GOTHIC-produced graphs denote sub-volume names with a T in front (e.g. TV7s15 is the same as V7s15).

5 Leak Locations 1, 2, and 3 lie in sub-volumes V7s15, V7s11, and V7s12, respectively.

6 o o Data points created by the GOTHIC analysis typically did not occur exactly at 145 F or 160 F. In order to increase the accuracy of the comparison between cases with and without fans, data points were interpolated and then rounded up to the nearest full second.

SUBJECT:

Turbine Building Temperature Response to Steam Leaks Conclusions Part 1 The analysis indicates that a steam leak rate of 32.90 Lbm/sec will result in elevated temperatures of 145oF and 160oF near the E31 thermocouples well within the acceptable time limit of 1 hr 11 min 46 sec.

Part 2 Comparing the results of the GOTHIC model, before and after the addition of the fans, reveals minor yet generally consistent effects. The time required to reach a setpoint of 145oF is decreased in all six cases by adding the fans. Also, a lower leak rate resulted in the fans having a larger effect for each case. The time required to reach a setpoint of 160oF is decreased in 5 out of 6 cases. Again, except in the case of Leak Location #1 during summer conditions, a lower leak rate resulted in the fans having a greater effect in their ability to decrease the time required for detection. The reason behind Summer Leak Location #1 not performing in line with the other cases can only be conjectured. It is assumed that because Leak Location #1 lies in the same subvolume as the thermocouples, air is being directed via the fans from a cooler sub-volume towards the thermocouples, while the leaking steam is being forced out of the vicinity of the thermocouples where it originates. Over the longer period of time it takes to reach 160oF vs. 145oF, the region surrounding the thermocouples is allowed to be homogenized to a greater extent with the surrounding cooler air. Beyond this special case, the results are consistent in predicting that the fans will help to homogenize the volumes and decrease the time for detection. Even in the instance that the time required is increased, all of the detection times still remain well within the acceptance criteria.

Note: Two anomalies have been identified in the final results represented in this Addendum to Calculation 2.4.6.14. The first anomaly is that there is no definining trend on when a specific leak location is the limiting leak location for a given set of cases/scenarios. The reason for this is not readily apparent. There are many potentially contributing factors to this anomaly that are taken into account in the GOTHIC model, such as the leak rate and location, outdoor temperature, ventilation into the room, forced convection by fans, flow paths into adjacent zones, and the fact that the leaks are being directed away from the thermocouples allowing greater mixing. This complex set of factors results in GOTHIC treating each specific case in an individualistic manner, thus creating a set of solutions in which intuitive trends can sometimes not be found.

The second anomaly is that, according to the graphical results, once it appears that steady-state has been reached in some cases, there is a slight decline in temperature over time. It is conjectured that the reason for this is due to thick concrete walls surrounding the control volume in which the steam leaks and thermocouples reside. Once the concrete walls are heated up to a certain threshold temperature, they are able to begin radiating heat to their surroundings, thus conducting heat away from the control volume in question. Verifying this reasoning would require additional GOTHIC models to be created and executed outside the scope of this calculation.
