ENCLOSURE1 Response to RAIs Related to NRC's April 19, 2011 Letter Tennessee Valley Authority - Watts Bar Nuclear Plant - Unit 2, Docket No. 50-391 Requests for Additional Information (RAI)

EMCB RAI 1 In response to Item 3.k. 1 of the Watts Bar Nuclear Plant (WBN), Unit 2, supplemental Generic Letter (GL) 2004-02 response (Reference 1), four out of the six load combinations for which the strainers were structurally qualified include loads due to either an operating basis earthquake (OBE) or a safe shutdown earthquake (SSE). However, no information was provided regarding the structural damping values used in the seismic analyses of the strainers, including their individual components, as part of the structural qualification of these components. Please provide the OBE and SSE damping values used for the strainer structures in the aforementioned analysis.

TVA Response The WBN Unit 2 OBE and SSE damping values used in the sump strainer were 2% and 3%,

respectively, per the TVA Advanced Design Containment Building Sump Strainer Design Specification, SQN-WBN-DS-2005-063-001, Rev. 2. Refer to Attachment 1 for excerpts from this specification which provide the WBN Unit 2 seismic spectra. These response spectra are similar to spectra used for analysis of the WBN Unit 1 strainer assemblies. The slight difference is due to steam generator replacement for Unit 1 which added mass to the reactor building.

These damping values are the same as used for Category I Equipment Seismic/Structural Qualification (ESQ).

EMCB RAI 2 Note 3 accompanying the loading combinations in Reference 1, which were considered in the structural analyses of the WBN Unit 2 sump strainers, indicates that loads due to jet impingement and debris impact were not considered in the final strainer design. The response to Item 3.k.3 of the WBN Unit 2 supplemental GL 2004-02 response clearly articulates that loads due to jet impingement are not credible, due to the location of the sump strainers.

However, there is little justification for neglecting the postulated loads due to debris impact.

Please provide additional justification and/or explanation regarding the conclusion of debris impact loads from the applicable loading combinations considered in response to Item 3.k. 1.

TVA Response Debris impact loads were included in Load Combination 6, but determined to be negligible based on the location of the WBN Unit 2 strainer assembly relative to postulated pipe breaks inside containment. This is the same reasoning as used for jet impingement loads, as stated in the response to Item 3.k.3.

Note that Load Combination 6 conservatively combines Safe Shutdown Earthquake (SSE) with applicable debris impact and jet impingement loads from postulated pipe breaks at the location of the component (i.e., the strainer assembly). The load combinations and allowable stresses used for strainer assembly structural analysis are consistent with WBN design criteria WB-DC-20-21 for miscellaneous steel components.

ENCLOSURE1 Response to RAIs Related to NRC's April 19, 2011 Letter Tennessee Valley Authority - Watts Bar Nuclear Plant - Unit 2, Docket No. 50-391 EMCB RAI 3 Note 6 accompanying the aforementioned loading combinations considered in the structural analyses of the WBN Unit 2 sump strainers, indicates that loads due to hydrostatic or hydrodynamic effects were not considered in the final strainer design. There is no accompanying justification for the exclusion of the effects of these loads in the sump strainer structural analyses. Please provide additional justification regarding the exclusion of hydrostatic and hydrodynamic loads. This justification should include, but not be limited to, whether submergence, sump strainer construction, or the bounding of these effects by other loads account for the absence of hydrostatic and hydrodynamic loads in the current structural analysis.

TVA Response Contrary to the above NRC question, Note 6 does not say that hydrostatic or hydrodynamic loads are excluded from the design. Instead, Note 6 states that these loads are not considered in combination with seismic Operating Basis Earthquake (OBE) or SSE loads. The WBN Unit 2 containment sump design basis does not require consideration of a seismic event during recovery from a design basis LOCA. As the containment sump strainers will only be subjected to accident hydrostatic or hydrodynamic loading during the recovery from a design basis event, application of hydrostatic or hydrodynamic loads to load combinations which include seismic loads is beyond the current design and licensing basis of the plants.

Hydrostatic loads are included in the differential pressure (DP) load as discussed in response to Item 3.k.l. The strainers are designed for a strainer maximum submergence of 14.42 ft above floor elevation at the top of the sump pit. These static loads to the strainer assembly and plenum were considered in determining the DP load. The DP load acts during accident conditions when the strainers are covered with debris. This is conservatively based on the maximum allowable hydrostatic pressure drop across the debris covered strainers of 3.5 feet of water.

ENCLOSURE2 Response to RAIs Related to NRC's April 25, 2011 Letter Tennessee Valley Authority - Watts Bar Nuclear Plant - Unit 2, Docket No. 50-391 Debris Generation (DG)

DG RAI-1 According to the Break Selection Evaluation, mineral wool is installed in limited locations, but was stated to not be within any loss-of-coolant accident (LOCA) zone of influence (ZOI). No ZOI size was provided for the mineral wool material. The basis for excluding the mineral wool as potential debris was not provided. Provide information to justify that the mineral wool cannot become transportable debris. Alternately, provide information to justify that the design basis debris load bounds any alternate debris load that includes the mineral wool.

TVA Response As stated in the response to Item 3.a.2, some mineral wool insulation is used inside containment but it is not in locations within the ZOI for any LOCA. A small quantity of mineral wool (1.57 ft3) is used where the under vessel in-core instrument tubes penetrate the crane wall. Mineral wool is also used inside the guard pipes on the main feedwater lines outside of the crane wall where the lines penetrate the steel primary containment. Upon blowdown, if this material were to fail, the mineral wool in the under vessel in-core instrument tube crane wall penetrations would be blown to the area outside the crane wall, which has no communication with the emergency sump inside the crane wall. Mineral wool inside the guard pipes on the main feedwater lines outside of the crane wall would remain outside the crane wall. Therefore, mineral wool is not considered transportable debris.

Head Loss and Vortexinq (HLV)

HLV RAI-1 The design basis assumes 750 ft2 sacrificial strainer area for miscellaneous debris (Section 3.b of submittal), During testing, the NRC staff understood that scaling included a 200 ft2 sacrificial area, as documented in the staff's trip report (ML102160226). Please reconcile this discrepancy.

TVA Response An initial conservative allowance of 1,000 ft2 of total surface area was used for signs, placards, tags, tape, etc., inside the containment. The initial assumption was used in the design of the strainers. The entire quantity of signs, placards, tags, tape and similar miscellaneous materials was conservatively assumed in the analysis to be transported to the sump intake. Based on Section 3.5.2.2.2 of the NRC SER for NEI-04-07, a 75 percent packing ratio was applied to this debris. Thus, 750 ft2 represents the strainer area assumed to be blocked by signs, placards, tags, tape, and similar miscellaneous materials in containment in response to Item 3.b.5. Based on containment walkdown results documented in WAT-D-1 1530 for Unit 1, a conservative estimate of the actual total surface area of all signs, placards, tags, tape and similar miscellaneous materials in containment was established as 697 ft2; thereby confirming the adequacy of the original design allowance. The allowance will be the same for Unit 2. It was later determined that this type of debris does not get transported to the sump screens due to the geometry of the containment and thus the final test did not include these types of debris.

The WBN Unit 2 strainer surface area is about 4,600 ft2. For the purpose of test scaling, the total surface area was assumed to be only 4,400 ft2 in order to add 200 ft2 of margin to the E2-1

ENCLOSURE2 Response to RAIs Related to NRC's April 25, 2011 Letter Tennessee Valley Authority - Watts Bar Nuclear Plant - Unit 2, Docket No. 50-391 strainer flow test results. The AREVA Debris Allocation Table for the WBN Unit 1 strainer performance test erroneously stated that this 200 ft2 area was removed for tags and labels.

This 200 ft2 does not represent a direct correlation to signs, placards, tags and tape, but as described above, was an assumed clean strainer area reduction to provide margin. Results from AREVA strainer prototype testing confirmed that tag and label debris does not readily transport to the sump strainer assemblies and thus, tags and label debris were not included in the testing.

HLV RAI-2 The application did not include a plot of the test strainer head loss as a function of time for the design basis test, annotated with significant events during the test, as described in the revised content guide for GL 2004-02 supplemental responses (ADAMS Accession No. ML073110278).

The NRC staff reviews the plot to validate extrapolation of test results to the mission time, and to ensure that pressure-driven bed discontinuities did not affect the debris head loss (such that temperature scaling may be inappropriate). Provide an annotated plot of the design basis test.

TVA Response The third Thin Bed Test was performed on July 16, 2010. This thin bed test represents the design basis test for WBN Unit 2 debris loaded head loss.

Figure 6-6 below from AREVA document number 66-9144025-000, Watts Bar Unit 1 Emergency Core Cooling System Strainer Performance Test Report, presents a plot of the head loss data versus time for the duration of Test 4C.

As can be seen, the head loss after 15 flume turnovers is constant and therefore is bounding for the 30 day mission time.

ENCLOSURE2 Response to RAIs Related to NRC's April 25, 2011 Letter Tennessee Valley Authority - Watts Bar Nuclear Plant - Unit 2, Docket No. 50-391 Note: The clean strainer average head loss is the average head loss before debris was introduced during Test 40.

Using the clean strainer and thin bed upper limit head losses from Table 6-8, the thin bed upper limit debris loaded head loss is:

5.76 (ft of water) - 3.88 (ft of water) = 1.88 (ft of water)

The temperature corrected thin bed upper limit debris loaded head loss is:

3.35 (ft of water) - 2.26 (ft of water) = 1.09 (ft of water)

Net Positive Suction Head (NPSH)

NPSH RAI-1 It is unclear how the margins reported for residual heat removal switchover time and containment spray system (CSS) switchover time are consistent with the strainer submergence values reported in section 3. f.2 of the Watts Bar 2 submittal. For the limiting case of small-break LOCA (SBLOCA), the minimum sump level is stated to increase from 5.78 ft to 6.91 ft from the time of emergency core cooling system recirculation to the time of CSS recirculation. This would contribute to a net positive suction head (NPSH) margin of 1.1 ft. The NPSH section of the submittal states that NSPH margin increases by about 3.7 ft when comparing similar conditions.

The change in submergence for a large-break LOCA reported in section 3.f.2 (3.4 ft) is closer to this value. There may be a discrepancy in the reported minimum sump level at CSS recirculation for the SBLOCA case. Clarify the water levels and discuss how the NPSH margins reported in section 3.g. 16 were calculated. Clarify the water levels and and discuss how the NPSH margins reported in section 3.g. 16 were calculated.

TVA Response The value for minimum sump level for the SBLOCA case reported in response 3.f.2 is incorrect.

The 3.f.2 response erroneously stated the sump level at the time of entering containment spray system (CSS) recirculation mode is 6.91 feet. The correct value is 9.39 ft which is the result of a 3.61 ft increase in sump water level. This 3.61 ft increase corresponds to the 3.7 ft NPSH margin increase seen in the 3.g.16 response as described below. Note 2 in the original 3.f.2 response states, "SBLOCA results are for the 120 gpm SBLOCA case. 2000 gpm SBLOCA was also examined in sump water inventory calculations for NPSH." The minimum sump level of 6.91 ft is actually the sump level at the time of emergency core cooling system (ECCS) recirculation for the 2000 gpm SBLOCA. The corrected values, including the values for the 2000 gpm SBLOCA case and the large break LOCA case from the latest revision of the analysis for minimum sump level, are shown below:

The sump level is an input to the MULTIFLOW model. The model is based on a maximum sump temperature of 1900F. Thus, a 3.61 ft change at 60°F and 1 atmosphere converts to 3.73 ft at 1900F, which rounds to 3.7 ft of NPSH margin.

E2-6

ENCLOSURE2 Response to RAIs Related to NRC's April 25, 2011 Letter Tennessee Valley Authority - Watts Bar Nuclear Plant - Unit 2, Docket No. 50-391 NPSH RAI-2 For SBLOCAs, Enclosure 3 indicates that the minimum water level calculation assumes the reactor coolant system (RCS) will contribute inventory to the reactor cavity. The applicant calculates RCS shrinkage, due to cooling of the primary inventory, and subtracts this value to reduce the amount of water that reaches the containment sump. It is not clear to the staff that the calculations account for the inventory required to refill the RCS, such that the stated amounts provide for conservative estimates of minimum sump level. The NRC staff's position is that the applicant should account for the potential for the RCS to become completely filled with water at it's ultimate equilibrium temperature. The staff understands that the levels may have been calculated correctly and that ice melt will contribute inventory at a rate required to account for RCS refill and cooldown. Provide information to demonstrate that the minimum sump level has determined properly considering the above discussion.

TVA Response Considering only the water inventory that spills from the RCS into the reactor cavity does not result in a level that will cause reactor cavity overflow to the sump for all SBLOCA minimum sump level determinations. The Reactor Cavity inventory is 128,000 gallons. The diversion of sump inventory from ECCS to maintain the Reactor Vessel filled was determined for a 4 inch SBLOCA of 2,000 gpm based upon the WBN Unit 1 SBLOCA Accident Analysis Parameter Checklist. As WBN Unit 1 RCS inventory is greater than WBN Unit 2, this is considered a conservative assumption. Initial RCS specific volume is based upon 2,235 psig and 586.2°F.

The cooldown is postulated to occur until RCS achieves 600 psia, the accumulator injection setpoint, as accumulator injection is not credited as a sump or RCS makeup source. The RCS remains at the equilibrium RCS hot and cold leg temperatures of 489°F and 260°F for an average RCS temperature of 374.5°F. This temperature and pressure were used to determine the RCS specific volume and shrinkage at ECCS and CSS recirculation initiation. The ECCS makeup due to RCS shrinkage for ECCS and CSS recirculation were the same since no further RCS shrinkage occurs to permit accumulator injection after ECCS recirculation initiation.

The diversion of ECCS sump inventory for a 2 inch SBLOCA of 120 gpm assumes the initial RCS specific volume is based upon 2235 psig and 586.2°F. The diversion of sump inventory from ECCS to maintain the Reactor Vessel filled was determined for a 2 inch SBLOCA of 120 gpm based upon WCAP-1 1145, Westinghouse Small Break LOCA ECCS Model Generic Study with NOTRUMP Code. RCS cooldown does not achieve equilibrium at the time of ECCS recirculation initiation. The RCS hot and cold leg temperatures at initiation of ECCS recirculation were 561.0°F and 474.70F for an average RCS temperature of 517.80F. The RCS pressure at initiation of ECCS recirculation was 1,167 psia.

The long-term cooldown is postulated to occur until RCS achieves 610 psig, the accumulator injection setpoint, as accumulator injection is not credited as a sump or RCS makeup source.

The long-term equilibrium RCS hot and cold leg temperatures were 509.40F and 362.20 F for an average RCS temperature of 435.80F. This temperature and pressure were used to determine the RCS specific volume and shrinkage at CSS recirculation initiation.
