When extending the CT of a TS in the proposed system lineup (i.e., 1X210 or 1X220 de-energized), the licensee will make one train of RHRSW and Emergency Service Water (ESW) inoperable by disabling power to the RHRSW array valves and the bypass valve. If during the revised CT of 7 days, the station experiences a dual unit loss of offsite power (LOOP) with a single failure of the redundant RHRSW train, both trains of RHRSW and ESW would be inoperable. The scenario presented in the enclosure to the LAR dated January 26, 2016 (pages 6 and 7 of 30) does not address this concern.

Based on this concern, provide results of an analysis stating how the station will mitigate a dual unit LOOP when in the revised CT of 7 days. The results of the analysis should do one of the following:

a. Provide reasonable assurance, with specified compensatory actions in place at the start of the planned maintenance, that the probability of failure of the remaining train of RHRSW has been significantly reduced to justify the 7-day CT; Or

b. Assume the only remaining train of RHRSW has failed with the LOOP, and with defined compensatory actions in place at the start of the planned maintenance, demonstrate that RHRSW can be restored such that safe shutdown and cooldown to Mode 4 can be achieved for both units, including cooling of the spent fuel pool. In your analysis,

i.

assume the LOOP duration is the full 7 days; ii.

identify the minimum time Unit 1 must be shut down in order for your analysis to be valid, since Unit 1 will already be in Mode 4; iii.

describe the operator actions and the associated timeline needed to restore an RHRSW header to service in order to provide decay heat removal for both units.

Response

This response will address question 1 b. In discussing the response to this question, it is important to understand the configuration and availability of the RHRSW and ESW pumps in the division that the work is occurring. The work will cause a loss of power to the bypass and spray array valves causing them to fail in their current position (bypass valve open and spray array valve closed). As part of the work, the spray pond bypass valve will be confirmed in the open position. This establishes a flow path for both RHRSW and ESW to the spray pond. The RHRSW and ESW pumps on the division being worked will have power available and be able to start in the event of a design basis accident (e.g., LOOP) since they are powered from the Emergency Diesel Generators (EDGs). Since the RHRSW pumps in the affected division will have AC power and a flow path to the spray pond, they will remain functional to remove decay heat as required.

Page 1 of 8 SSES Response to RAl A potential issue that may impact RHRSW and ESW pump functionality is the loss of all ESSW Pumphouse ventilation fans in the affected division. Analyses have been performed to demonstrate that if the doors or dampers are configured in a specific manner, the natural circulation of air will keep the affected division temperature within pump operability limits. The analyses conservatively assumes design basis outside air temperatures. The required configuration will be established at the start of the work.

With the above actions in place at the start of the assumed event (LOOP), both RHRSW pumps in the affected division will be available for decay heat removal. The ESW loop in the affected division will be available to provide cooling water flow to the diesel generators and other ESW users. The operating unit RHR system will be aligned for suppression pool cooling or shutdown cooling when the RHR shutdown cooling pressure permissive is reached. The plant operator will align RHR in fuel pool cooling mode for the shutdown unit. This would cool both the fuel pool and the shutdown core assuming the core and fuel pools are connected though the reactor cavity. Operational experience has demonstrated that the non-safety related fuel pool cooling pumps can cool both the fuel pools and the core during outages. The RHR fuel pool cooling mode has a greater cooling capacity than the fuel pool cooling system so both the core and fuel pools will be cooled by the outage division RHR system.

The only long term concern of this approach is maintaining peak spray pond temperatures within the current analytical bounds. In the scenario analyzed to address this question, it is assumed only the affected division of RHRSW/ESW is available (i.e. the division with an open bypass valve). The spray pond temperature will increase in this valve alignment. The spray pond bypass and spray array valves are located in a valve vault near the spray pond. Plant personnel will be designated to manually position these valves in the event of an accident resulting in the loss of the operable loop of RHRSW/ESW cooling. This will provide cooling for the spray pond and maintain temperatures within design limits. This manual action will conservatively take less than 2 hour2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months to perform. To determine the impact on spray pond temperature, this time will conservatively be doubled. If the initial spray pond temperature is maintained below 82°F, the peak pond temperature will be bounded by the current analysis assuming Unit 1 has been shut down for at least 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months .

To summarize, the following conditions will need to be met:

1. One unit in Mode 5 for at least 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months with the core and fuel pools connected through the reactor cavity

2. Spray pond temperature is maintained below 82°F

3. ESSW Pumphouse doors or dampers aligned to provide adequate cooling

4. Designated personnel to open the spray array valves and close the bypass valve Based on the above discussion, one division of RHRSW and ESW will remain functional throughout a LOOP and temperatures will remain within current analytical bounds assuming the failure of the division unaffected by transformer replacement.

Page 2 of 8 SSES Response to RAI RAI2:

In Table 1 in the enclosure to the LAR dated January 28, 2016 (pages 16 through 27 of 30), the licensee listed Unit 2 and common loads that are powered by Unit 1 Class 1 E 480 V transformers and are affected by de-energization with the associated Limiting Conditions for Operation (LCO) and Technical Requirements for Operation (TRO) implications.

In Enclosure 1 to the licensee's letter dated April 6, 2016, the licensee provided a listing of loads from the motor control centers (MCCs) powered by the Unit 1 Class 1 E 480 V transformers that will be replaced as identified in the LAR.

From a correlation of the loads listed in Table 1 of the LAR dated January 28, 2016, with the loads identified Enclosure 1 of the letter dated April 6, 2016, the NRC staff notes that a small percentage of the loads listed in Enclosure 1 is subsequently identified in Table 1 of the LAR as affecting Unit 2 LCOs and TROs. Many of the affected loads listed in Enclosure 1 have identifiers that do not clearly distinguish between Unit 1, Unit 2, and common loads. Therefore, the NRC staff requests that the licensee:

a. Provide a listing of all Unit 2 or common loads powered from the Unit 1 480 V transformers (1X210, 1X220, 1X230, and 1X240) listed in Enclosure 1 and that are:

1) safety related or Class 1 E and

2) not already identified in Table 1

b. For any loads identified above, determine if any LCOs or TCOs are associated with these loads, and discuss additional actions (if applicable) necessary to justify the LAR.

Response

a. See Enclosure 1.

b. There are no additional LCOs or TROs associated with this equipment. As a result no additional actions are required.

RAI 3

In Table 1 in the enclosure to the LAR dated January 28, 2016, the licensee has identified TRO 3.7.6 associated with the Engineered Safeguard Service Water (ESSW) Pumphouse Ventilation System. When either transformer 1X21 0 or 1X220 is being replaced, four ESSW fans are inoperable. The licensee stated in Table 1 that two ESW pumps and one RHRSW pump would be declared inoperable after 36 hours4.166667e-4 days 0.01 hours 5.952381e-5 weeks 1.3698e-5 months in accordance with TRO 3.7.6. The NRC staff does not have TRO 3.7.6 to review, and it is not clear why only one RHRSW pump would be inoperable.

The staff requests that the licensee:

Page 3 of 8 SSES Response to RAI

a. Explain why only one RHRSW pump becomes inoperable after 36 hours4.166667e-4 days 0.01 hours 5.952381e-5 weeks 1.3698e-5 months with two RHRSW fans out of service when either 1X210 or 1X220 is being replaced.

b. Provide a copy of TROs 3.7.6, 3.8.6, 3.7.9, 3.3.4, and 3.11.2.6 (i.e., TROs referenced in Table 1).

Response

a. Table 1 provides the details of the required LCO entries and the basis for the required timeframe. Due to the loss of the MCC, one division of ESSW Pumphouse ventilation will not be operable. Per the SSES Technical Requirements Manual Section 3.7.6, the associated pumps in that division need to be declared inoperable if at least two ventilation subsystems are not restored to operable status within 36 hours4.166667e-4 days 0.01 hours 5.952381e-5 weeks 1.3698e-5 months . Both RHRSW pumps (Unit 1 and Unit 2 pump) and both ESW pumps in the affected division will become inoperable. The table incorrectly identifies that only 1 RHRSW pump would be declared inoperable.

b. Copies of TRM Sections 3.7.6, 3.8.6, 3.7.9, 3.3.4, and 3.11.2.6 are provided in. Common TROs (Unit 0; used by both Unit 1 and 2) only have 1 TRO filed under Unit 1. These TRM sections list all associated TRO actions and allowed timeframes for the completion of those actions. An additional TRO not previously identified is also provided (TRO 3.7.1). TRO 3.7.1 covers the operability of the ESW system in Modes 4 and 5 and also during movement of irradiated fuel in Secondary Containment.

RA14:

On page 8 of the enclosure to the LAR dated January 28, 2016, the licensee provides the sequence/flow path for replacement of a 480 V Engineered Safeguard System (ESS) Load Center (LC) Transformer and information that applies throughout the evolution. The following questions relate to provisions that the license will make in order to limit the potential loss of power to Unit 2 equipment during the replacement of all Unit 1 480 V ESS LC Transformers that feed both units:

a. The licensee provided a list of surveillances that will be performed prior to the transformer replacement sequence. What test/surveillance will the licensee perform to verify that all structures, systems, and components are operable prior to entering the transformer replacement sequence?

b. What compensatory measures will the licensee take in order to limit the potential loss of power to Unit 2 during the replacement of all Unit 1 480 V ESS LC Transformers (e.g.,

scheduling the evolution in order to avoid anticipated severe weather conditions, corridor the work zone as a Protected Area, restrictions on the maintenance of the switchyard, contacting the grid system load dispatcher to ensure no significant grid perturbations are expected)?

Page 4 of 8 SSES Response to RAI

Response

The station performs surveillances as required by Technical Specifications and the Technical Requirements Manual. As required by 10 CFR 50.65(a)(4), the risk of performing maintenance is assessed and mitigated prior to commencing. The control and assurance of safety required to perform this work is built in to normal station processes as required by regulation.

a. Assurance of systems capabilities during the evolution:

Since this work impacts power sources on the Class 1 E Distribution system, surveillance testing is focused on testing associated with Diesel Generator capability to power all other ESS busses. SR requirements 3.8.1.3/3.8.1.7 are performed under approved station procedures for each emergency diesel generator (EDG). SSES has 4 EDGs that are connected to the class 1 E distribution system to meet LCO 3.8.1. Diesels are tested monthly to ensure the ability to start from standby condition and achieve rated parameters within their required start times. Additionally, surveillance requirements ensure the EDGs are capable of providing emergency power for the full duration of which they are required.

Prior to transformer replacement, the 24 month LOCA/LOOP surveillance will be performed for the same division in the maintenance window. This assures that response of the other bus in that division and the diesel including safety related loads and load timers are all operable and performing as designed.

Prior to commencing transformer work, a review will be performed to determine if LCO 3.0.6 has been applied to either unit for any reason. If it has, a Loss of Safety Function analysis is performed. This ensures the ability to perform a safety function assumed in the accident analysis can be performed with the equipment verified operable. A Loss of Safety Function (LOSF) exists when, assuming no concurrent single failure, loss of offsite power, or loss of on-site diesel generator(s), a safety function assumed in the accident analysis cannot be performed. This LOSF review ensures all other systems structures and components are operable prior to commencing transformer work.

b. Actions to be taken during the evolution:

Actions to be taken in severe weather conditions are implemented by Operations shift personnel using approved procedures. These procedures instruct the evaluation and termination of non-essential or operationally risk significant activities. This includes discussion with transmission to evaluate impact of weather to the grid.

When notified, station procedures require the evaluation of work and assessment of risk based on grid operator notifications of alerts/warnings by operations shift supervision and work management.

The risk of emergent conditions is governed by approved station procedures which ensure the emergent conditions are included in the previously performed Page 5 of 8 SSES Response to RAl RAIS:

risk assessment and ensure the reassessed risk is acceptable. The online work week manager performs risk assessments for work performed in Modes 1, 2, and

3. The outage risk assessor performs EOOS shutdown risk assessments for work in Modes 4 and 5. The potential impact of severe weather on upcoming work is considered in these assessments.

One division of Diesel generators (2 DGs on the opposite division) is protected to ensure reliable electrical power to supply the outage Unit key safety functions.

This also facilitates strict control of entry into those DG rooms and limits what activities are allowed to occur. This ensures that reliable AC power to the opposite division will be present during a LOOP concurrent with transformer replacement.

The offsite power sources of TS 3.8.1 are both protected during the outage. The SSES portions of this protection are governed by the protected equipment program. Protection also extends to the switchyard owned by PPL Electric Utilities. The protection of components owned by PPL electric utilities needed by Susquehanna is protected using PPL Electric utilities processes. By procedure, SSES approves the protection scheme and references these schemes in SSES protection clearances. The interface between PPL electric utilities and Susquehanna is governed by a separate procedure.

The division opposite the transformer being replaced does not have work going on in parallel. This is controlled by the outage schedule and the status file review that occurs during the divisional swap. Additionally the divisional windows have their own codes for shutdown equipment out of service and as such are captured when risk is run in the EOOS program. Protected equipment on the opposite division also includes Core Spray/RHRIRHRSW/ESW/Power supplies to support the key safety functions of decay heat removal and inventory control.

The opposite division is also supporting decay heat removal and therefore has power supplies and support systems protected to ensure the key safety function of DHR is not compromised. Support systems include RHRSW and ESW. The protection of ESW to support DHR also maintains its availability to support Unit 2 loads and 4 EDGs.

On page 3 of the enclosure to the LAR dated January 28, 2016, the licensee stated that the ESS LC supplies power to the individual 480 V loads and to MCCs that power instrument alternating current (AC) distribution panels, 125 and 250 V direct current (DC) battery chargers, and essential plant lighting. Discuss in detail the impact of the replacement of a Unit 1 480 V ESS LC Transformer on the Unit 2 instrument AC and DC power system loads. Explain how the Unit 2 DC power system continues to permit functioning of structures, systems, and components important to safety during the replacement of a Unit 1 480 V ESS LC Transformer.

Page 6 of 8 SSES Response to RAJ

Response

The impacted Unit 2 instrument AC and DC power system loads supplied by Unit 1 are listed below.

Load Normal Power Source Alternate Power Source 2D613-U-2 125V DC BATTERY OB516 Can be aligned to 2B210 via 0-ATS-516 CHARGER OB516071 2D623 - U-2 125V DC BATTERY OB526 Can be aligned to 2B220 via 0-A TS-526 CHARGER OB526071 2D633 - U-2 125V DC BATTERY OB536 Can be aligned to 2B230 via 0-A TS-536 CHARGER OB536071 2D643 - U-2 125V DC BATTERY OB546 Can be aligned to 2B240 via 0-ATS-546 CHARGER OB536071 Based on all loads above having alternate power sources, the Unit 2 DC power system continues to permit functioning of structures, systems, and components important to safety during the replacement of a Unit 1 480V ESS LC Transformer Replacement. Loads will be aligned to alternate power sources as required to complete the work.

RAI6:

In Enclosure 1 to the April 6, 2016, letter, the licensee provided a table with the affected loads listed by transformer. For the Unit 2 Class 1 E loads powered from Unit 1, identify the alternate source of power/alternate train that would be used during the Unit 1 transformer replacements.

Response

The only affected Unit 2 loads affected by the proposed evolution are the battery chargers identified in RAI 5. To support the transformer replacement activities, the chargers will be aligned to their alternate power sources as specified.

RAI7:

The enclosure to the LAR dated January 26, 2016 (pages 8 and 9 of 30) presents a list of bulleted items that will apply throughout the evolution and a flow path for replacement. Provide more complete justification, including time estimates for why a full 7-day CT is needed.

Response

Work schedules developed by experienced schedulers were drafted using typical/historical values for a 480 V ESS Load Center transformer replacement evolution. The schedules show that 108 hours0.00125 days 0.03 hours 1.785714e-4 weeks 4.1094e-5 months of work is required strictly to replace the transformer.

This includes time to perform all work that cannot be performed outside of the LCO, such as:

Page 7 of 8

Attachment I Clearance order application Pre-evolution testing and maintenance SSES Response to RAI Engineering review of test results that may influence the scope or schedule of work to be performed The replacement itself Work that supports the replacement evolution such as scaffold, rigging, welding Post-evolution testing and maintenance The schedule considers human factors such as shift turnover and fatigue rule restrictions, further making the estimate realistic. The schedule does not consider any contingent replacements that may occur. This could include replacement of the surge arrestors, cables, and various other components. The risk of unanticipated outcomes weighed against Completion Times is a primary driver in planning evolutions such as this. The anticipated duration of 108 hours0.00125 days 0.03 hours 1.785714e-4 weeks 4.1094e-5 months is approximately 65% of the requested time (168 hours0.00194 days 0.0467 hours 2.777778e-4 weeks 6.3924e-5 months ). This will accommodate unexpected responses or maintenance that may result during the transformer replacement.
