5.0 COMPUTATIONS AND ANALYSIS This calculation documents the results of analyses to determine the NPSH available for the pipe routing and configuration from the ECCS suction strainer to the pump suctions for both the RHR and CS piping systems. NPSH margins are calculated for selected system maximum flow rates and suppression pool temperatures. System operating conditions and modes of operations are considered in determining flow rates and temperatures.

The Net Positive Suction Head (NPSH). is defined as the minimum head required to prevent cavitation in piping systems and pumps. The Net Positive. Suction Head Required (NPSHR) for the RHR and CS pumps is determined from the pump vendor curves (references 3.1 and 3.2). The difference between NPSHA and NPSHR is the NPSH margin.

t The NPSHA is the actual fluid energy delivered to the pump impeller through the piping configuration and is calculated by the following equation.

NPSHA = h, + h, - hr - h~ (Reference 3.3)

NPSH Evaluation of Browns Ferry RHR and Rev. Prepared Date CS Pumps Checked Date where:

h, = Atmospheric head = Suppression Pool airspace pressure h, = Static pressure head = Elevation difference between the center line of the pump inlet and the suppression pool water level.

hr = Total friction head loss = hr, + hr~

hr, = Friction head loss (pressure drop) across the suction strainer.

hr~

= Friction head loss in pipe.

h~ = Vapor pressure head.

The Browns Ferry Plant ECCS configuration includes an ECCS ring header circumscribing the suppression chamber with connecting piping to four inlet penetrations through the P torus wall into the su ression pool. Inside the suppression pool, each connecting line is fitted with a piping of the (RCIC) systems.

)ipse@

Since the ECCS ring header and the connecting piping to the ECCS strainers is common to the suction of all of the ECCS pumps, the flow and pressure distribution for the ring header and strainers is different for varying system demands. Therefore, to determine individual ECCS pump suction pressures for various plant states, a model of the suction piping configuration was created from TVA drawings (Reference 3.4) for analysis with the EZFLOW computer program (Reference 3.5). A simplified layout of the EZFLOW model for the ECCS ring header and suction piping to the RHR and CS pumps is shown in Figure 1. All model link input dimensions and components were summarized from TVA drawings (Reference 3.4) which contained confirmed systems configuration and dimensions.

For each piping link in the model, piping lengths included the total piping isometric dimension. When drawings did not specify whether a piping elbow was short or long radius, the conservative case, e.g. short radius, was chosen. In the RHR 30" suction lines from the ring header, 67.5'hort radius elbows were modeled as 90'ong radius elbows since EZFLOW does not easily enable modeling of the oF-nominal bend. For all form losses(elbows, valves, etc.), the EZFLOW default values of equivalent length, resistance, etc. were selected. It was also chosen to ignore resistance of piping tees having zero branch flow. The piping roughness value was selected as .00015 which is acceptable for a condensate quality system and would not be expected to change with system age.

Subject:

NPSH Evaluation of Browns Ferry RHR and Rev. Prepared Date CS Pumps Ch eel<ed Date The piping model was not extensive in terms of elevation changes. In order to assist analysis convergence, "dummy" check valve components were installed in the piping links from the strainer flanges to the ECCS ring header tees. The model was enhanced further by using this component to also represent ECCS strainer head loss as a function of fiow. To do this, head loss values versus flow from strainer sizing calculations were utilized.

C The important function of the HPCI and RCP( systems is for events that do.not result in g I/I'ff'ifi depressurization of the reactor vessel to the level where the low pressure ECCS systems (RHR and !

is@

CS) operate. Therefore, maximum flows for RHR and CS pumps for NPSH purposes in this calculation do not consider the demands of these systems.

Pump static suction head is equal to the available water level above pump suction centerline.

In the EZFLOW model, the static suction head at the strainer flange node is needed to be established for calculation purposes. It is necessary to establish this value in psig in the EZFLOW model at the strainer flanges. From TVA drawings (Reference 3.6), the low water level of the suppression pool is 536'1.75" with hp.

a:4'References 3.7.a and b.)

h =4 sin 40'=2.57'2'7" Pt. A elevation = 525'4" + 2'7" = 527' 1".

and static head to Pt. A = 536'1.75" - 527'l l" = 8'2.75" = 8.23' 95'F, II, = 8.23ft

62.06 N/ft/ 144 in /ft = 3.55 psig and this pressure was established at the strainer flange points (nodes 1, 5, 23, and 27)

NPSH Evaluation of Browns Ferry RHR and Rev. Prepared Date CS Pumps Checked Date System design flow values for RHR were taken from reference 3.8 and for CS were taken from reference 3.9. Maximum RHR flows are restricted by plant modifications which installed orifices in each RHR pump discharge and in the test return line (References 3.10 and 3.11).

The EZFLOW model calculation accounted for system static head and,piping friction losses. To obtain the NPSH available, it was necessary to adjust the EZFLOW pump suction pressure separately to add h, (normal suppression pool airspace pressure plus containment overpressure (based on the analysis of Reference 3.16)), to subtract fiuid condition vapor pressure h~

(at the analyzed suppression pool temperature), and to include the value of the simulated strainer head loss. The result is the available NPSH. Reduction of these values by the specific pump required NPSH values from vendor pump curves (References 3.1 and 3.2) and the head loss of a designed ECCS strainer (Reference 3. 1P) results in the final NPSH margin for the pumps.

Flow conditions of the RHR and CS systems analyzed were 1) maximum flow at a pool temperature of 95'F with no operational reduction, 2) maximum flow combinations at pool temperatures of 140'nd 150'F with no operational reduction, and+ Long term operation at the < t(ii)'i8 g@ii/nI; suppression pool design temperature limit of 177'F at design required system flows at that !

condition.

6.0 RESULTS AND CONCLUSIONS With credit for a containment pressure of 2 psig, positive margin to pump required NPSH exists for all plant conditions analyzed. Summary values of pump NPSH margin are shown in Tables 1 and 2 for the RHR and CS pumps respectively. Table 3 is a total summary of the pertinent EZFLOW data and the detailed EZFLOW case results for Unit 2 and Unit 3 are included as Appendices 1 and 2.

After 10 minutes the paint debris head loss is greater than the RMI head loss (0.98 versus 0.24 feet) but the revised higher head loss remains significantly lower than the maximum allowable (4.41 ft.). It is also of interest to note that after 10 minutes, the sum of the RMI and the paint 8 fsupplement 1

DRF E12-00164-00 October 8, 1998 Page 3 debris head loss (0.06+ 0.80 + 0.18 = 1.04 ft.) remains well below the maximum allowable head loss. In conclusion, under these assumptions, the Browns Ferry ECCS strainers can process the required 10,000 fthm of containment coating debris in addition to the RMI debris and the other fiber plus miscellaneous debris.

Concern Re ardin Assum tion That RMIand Increased Paint Debris Head Losses Are Not Additive GE calculations have shown that the combined bulk volume of fiber debris and the relatively large quantity of containment coating debris is approximately 4.2 cubic feet, and this is a small fraction of the Browns Ferry strainer gap volume (greater than 20 cubic feet). Under these conditions it is likely that a significant fraction of the perforated plate area will remain free of both fibrous and paint debris. Under these conditions the RMI head loss (plus the clean strainer head loss) would be equal to the total strainer head loss (the RMI and paint debris head losses would not be additive). This approach is consistent with the URG for ECCS Strainer Blockage; however, as noted earlier the NRC has suggested plant specific verification of this assumption. The bases for justification of the adequacy of the Browns Ferry ECCS strainer design (considering the increased volume of paint debris) are as follows:

~ The high head loss during the first 10 minutes of the LOCA is because of extremely high RHR flow rates. As the head loss increases with increased debris collected on the strainer, the reactor operators would likely reduce the flow rates to maintain an acceptable pump NPSH.

~ After 10 minutes the problem disappears when the pump flows are reduced.

Significant pump degradation during this short interval is unlikely.

~ Results of proprietary testing performed by Duke Engineering for Vermont Yankee demonstrated that turbulent energy in the suppression pool which is sufficient to entrain paint debris will also inhibit debris accumulation on low approach velocity ECCS strainers. At medium LOCA energy levels (reference NUREG-6368), the pool turbulence facilitated preferential deposition of the fiber on the strainer when compared to deposition of paint debris. If this phenomenon is extrapolated further, there is question of whether substantial quantities of RMI debris will ever be collected on low approach velocity strainers since this material (in addition to the paint debris) will settle to the suppression pool floor after pool turbulence subsides (5 to 15 minutes following LOCA initiation pending size of pipe break).

l. I0,000 ft~ epoxy coating debris weighs 559 Ibm. based on TVA provided value of 0 0 Ibm. per 179 ft2 epoxy/IOZ debris.
2. Paint debris head loss calculation based on testing of GE prototype strainer (209.3 Ibm. tested). [Reference 4]
3. Paint debris head loss is linear with debris bed thickness.
4. Since flow is turbulent across paint debris bed, the head loss is not a function of viscosity or temperature. This assumption also applies to RMI debris and was accepted by the NRC.
S. Paint debris head loss is proportional to the square of the strainer flow rate.
This is expected when the flow is turbulent and is applicable also to RMI debris.
8. The Rockwool and other miscellaneous debris (not including the paint debris) blocks 50% of the Browns Ferry strainer perforated plate area (50%
of 298 square feet). The fiber quantity is 2.94 cubic feet and the strainer gap volume is greater than 20 cubic feet. Since the strainers load preferentially toward the inner portion of the strainer this assumption is believed to be conservative. The unblocked 149 square feet is then assumed available for processing the relatively large quantity of paint debris.
