NRC, "Submittal of Relief Requests Associated with the Fourth Inservice Testing Interval," dated June 22, 2015 (2) Email form J. Wiebe (NRC) to J. A. Bauer (Exelon Generation Company, LLC), "Preliminary RAls for Relief Request RP-1," dated October 15, 2015 In the Reference 1, Exelon Generation Company, LLC (EGC) requested approval of five proposed relief requests in accordance with 10 CFR 50.55a, "Codes and standards." These relief requests are associated with the Fourth 10-Year Inservice Testing (IST) Program Interval for Byron Station. The Fourth 10-Year Interval begins on July 1, 2016 and is required by 10 CFR 50.55a(f)(4) to comply with the requirements of the American Society of Mechanical Engineers (ASME) Operation and Maintenance (OM) Code, 2004 Edition through the 2006 Addenda.

In Reference 2, the NRC requested additional information related to Relief Request RP-1 which addresses the Essential Service Water Makeup Pumps' vibration limits. It was agreed that the response to the request for additional information would be submitted to the NRC on or before November 30, 2015. The subject response is presented in Attachment 1.

As noted in Reference 1, the Byron Station Fourth 10-year IST Interval will be in effect from July 1, 2016 to June 30, 2026; accordingly, EGC respectfully requests approval of the subject relief requests by June 22, 2016.

ATTACHMENT 1 Response to Request for Additional Information Related to Relief Request RP-1 In the Reference 1, Exelon Generation Company, LLC (EGC) requested approval of five proposed relief requests in accordance with 10 CFR 50.55a, "Codes and standards." These relief requests are associated with the Fourth 10-Year Inservice Testing (IST) Program Interval for Byron Station. The Fourth 10-Year Interval begins on July 1, 2016 and is required by 10 CFR 50.55a(f)(4) to comply with the requirements of the American Society of Mechanical Engineers (ASME) Operation and Maintenance (OM) Code, 2004 Edition through the 2006 Addenda.

In Reference 2, the NRC requested additional information related to Relief Request RP-1 which addresses the Essential Service Water Makeup Pumps' vibration limits. The response to the NRC's request is presented below.

RAI-RP-1-1 Provide vibration history from 2001 to present and history of maintenance activities performed or corrective actions taken (if any) since 2001.

Response

Based on a clarification call with the NRC on October 29, 2015, it was agreed that providing vibration and maintenance history data from July 2006; i.e., the start of the Third Inservice Testing Interval, to present would be acceptable. The subject vibration data is provided in Attachment 1-1, and the maintenance history is provided in Attachment 1-2.

RAI-RP-1-2 ASME OM Code, paragraph ISTB-5223(d) requires, in part, that "vibration (displacement or velocity) shall be determined and compared with corresponding reference values. Vibration measurements are to be broad band (unfiltered). If velocity measurements are used, they shall be peak. "

However, in the letter dated March 1, 2001 from Philadelphia Gear Corporation (PGC) to EGC, PGC stated, in part, that the recommended maximum levels of filtered housing vibration in terms of velocity is 0.3 inch per second (ips). It appears that the PGC recommended ALERT RANGE of 0.55 ips was based on filtered vibration measurements. Therefore, it is not clear if filtered vibration measurements are used in the Byron IS program.

Provide confirmation that in the Byron 1ST program, the proposed gearbox vibration value of 0.55 inch per second is unfiltered and peak, as required by the ASME OM Code, IS TB-5223(d).

Response

Exelon confirms that the proposed gearbox vibration value of 0.55 inch per second is unfiltered and peak, as required by Maintenance procedures MA-AA-716-230-1005, "AMS Suite:

Machinery Health Manager Database Setup Guideline," and MA-AA-716-230-1008, "Setup and Operation of CSI 2130 Handheld Vibration Monitoring Equipment Using AMS Suite: Machinery Health Manager and the Standalone Data Transfer Software." The vibration data is collected

ATTACHMENT 1 Response to Request for Additional Information Related to Relief Request RP-1 using Byron Operating procedure OBOSR 5.5.8.SX.5-1(2)c, "Unit Zero Comprehensive Inservice Testing (IST) Requirements For Essential Service Water Makeup Pump OA(B)."

RAI-RP-1-3 RP-1 is requested under 10 CFR 50.55a(z)(1). This alternative request should be requested under 10 CFR 50.55a(z)(2), because compliance with the ASME OM Code requirements would result in increased test frequency which may be considered as hardship to the licensee.

Provide details of the hardship associated with increased test frequency such as increased man-hours and dose (if any).

Response

Exelon concurs that Relief Request RP-1 will be requested in accordance with 10 CFR 50.55a(z)(2), "Hardship without a compensating increase in quality and safety." In summary, placing the SX Makeup pumps in double test frequency due to their normal vibration levels would result in 7040 additional man hours, increased pump run time/pump component degradation, confined space entry hazards and inclement weather executions over the Fourth 10-year IST Interval. A revised copy of Relief Request RP-1 is provided in Attachment 1-3.

This revision of RP-1 replaces the previous revision of Relief Request RP-1 submitted in Reference 1 in its entirety.

RAI-RP-1-4 The spectral analysis has been performed as part of the second and third ten year IST program. However, RP-1 did not specifically reference spectral analysis. Performing spectral analysis enhances the ability of monitoring and detecting pump degradations.

Provide reasons or rationales for not addressing or not performing spectral analysis in the fourth 10-year 1ST program.

Response

Spectral analysis will be performed on SX Makeup Pump vibration data throughout the Fourth IST Interval. Future advanced analysis techniques, equivalent to spectral analysis, may be performed in lieu of spectral analysis.

1. ASME Code Component(s) Affected OSX02PA Essential Service Water Makeup Pump A OSX02PB Essential Service Water Makeup Pump B

2. Applicable Code Edition and Addenda

ASME OM Code 2004 Edition through the 2006 Addenda.

3. Applicable Code Requirement

Table ISTB-5221-1, "Vertical Line Shaft and Centrifugal Pumps Test Acceptance Criteria."

4. Reason for Request

In accordance with 10 CFR 50.55a, "Codes and standards," paragraph (z)(2), relief is requested from the requirement of ASME OM Code Table ISTB-5221-1. The basis of the relief request is that the Code requirements present an undue hardship without a compensating increase in the level of quality and safety. Table ISTB-5221-1 specifies the vibration limits for vertical line shaft pumps operating at or above 600 rpm as the following for both the Group A and the comprehensive pump test:

Reference Value Acceptable Alert Required Action Vr < 2.5 Vr >2.5 Vr - 6.0 Vr or >6.OVr or

>0.325 - 0.70 in/sec >0.70 in/sec Due to the unique design of these pumps, normal vibration levels have been as high as approximately 0.5 in/sec at the gearbox locations. As a result, the normal vibration levels may exceed the Acceptable and Required Action limits of Table ISTB-5221-1.

5. Proposed Alternative and Basis for Use The objective of the essential service water (SX) make-up pump is to maintain cooling tower basin level to compensate for drift losses, evaporation, and blowdown. These pumps automatically start on a low level signal in the cooling tower basin. The pump will continue to operate regardless of whether offsite power is available or not since these pumps are diesel engine driven.

The essential service water make-up pumps are categorized as Group B since they are in a standby system which is not operated routinely except for testing.

ATTACHMENT 1-3 10 CFR 50.55a Request Number RP-1 Page 2 of 6 The SX Makeup Pumps are a unique design (see Figure 1). A horizontal diesel drives a right angle gearbox located approximately 39 feet above the pump. The driveshaft from the gearbox to the pump consists of five coupled sections and is located in the pump discharge piping column. Pump thrust is carried by bearings physically located within the gearbox. The pump is submerged in river water.

Although these pumps are considered vertical line shaft pumps, the unique design configuration is not addressed by the ASME OM Code. Due to monitoring limitations of this design, and because of the similarity to the requirements for vertical line shaft pumps, vibration is monitored on the gearbox. The limitation of taking the vibration readings at this location is that the resultant vibration readings are not attributable to the pump. Vibration analysis has indicated the vibration readings obtained are the result of vibration induced by the diesel engine and the gearbox itself, along with a resonant condition of the gearbox and its foundation.

Maintenance and inspection activities to date have indicated that the angle gearboxes have been operating properly and without degradation. Maintenance and inspection activities on the pumps have indicated that there has not been any pump degradation due to the vibration observed on the gearboxes. Likewise, the pump units have not caused vibration degradation of the gearboxes. As expected, since these pumps are Group B, little to any degradation has been identified.

The pump impellers have been replaced with stainless steel units and the wear rings replaced with a more resistant alloy, due to the adverse service application associated with these pumps. The new pump assemblies were tested at the vendor's facility and exhibited very low vibration levels.

Byron Station had consulted an industry vibration expert and vendor representative from the gearbox company in 2001 (see Figure 2), in an effort to ensure vibration levels are as low as achievable with this particular pump design, and to assure the existing vibration levels are not indicative of pump degradation. These efforts included the following activities:

Field service representatives from the gearbox company supervised the refurbishment of the two gearboxes. Both refurbished units were then installed on the pumps. The units that were refurbished had seen a significant amount of service under the historically higher vibration conditions and when inspected did not show any vibration related degradation.

Bi-directional support braces were installed on the gearboxes to address the vibration resonance problem.

The gearboxes were precision aligned and the couplings were balance checked upon installation.

All of these efforts combined have resulted in some reduction in the vibration levels; however, not enough to remove the pumps from the ASME OM Code Alert Range. Both pumps have experienced vibration levels at the gearbox locations of up to approximately

ATTACHMENT 1-3 10 CFR 50.55a Request Number RP-1 Page 3 of 6 0.5 in/sec during the third 10 year inservice testing interval. Byron has concluded that vibration levels recorded at the gearbox locations are normal for the unique design configuration and do not indicate an unusual condition of the gearbox or the pump. The proposed alternative limits below will ensure that required action is taken if vibration levels increase while ensuring the pump is not prematurely declared inoperable.

Since the gearbox normally exhibits relatively high vibration levels, which are not indicative of degradation, the use of Table ISTB-5221-1 would not be practical in that it would require double test frequency when the vibration levels are normal.

Placing the SX Makeup pumps in double test frequency with their normal vibration levels would result in 7,040 additional man hours, increased pump run time/pump component degradation, confined space entry hazards and inclement weather executions over the fourth 10-year IST interval.

Byron Station proposes the use of the following limits when performing vibration testing of the SX Makeup Pumps:

Reference Value Acceptable Alert Required Action Vr < 2.5 Vr or >2.5 Vr - 6.0 Vr or >6.OVr or

<_ 0.55 in/sec >0.55 0.70 in/sec >0.70 in/sec Increasing the Alert Range limits for these pumps would ensure that pumps are placed in double test frequency at a vibration level that would be abnormal for the SX Makeup Pumps' design configuration.

The basis of the >0.55 in/sec Alert limit was based on vendor concurrence and previous approval of this request during the third 10-year IST interval (See Figure 2 Vendor Concurrence Letters).

Using the provisions of this relief request as an alternative to the specific requirements of Table ISTB-5221-1 identified above will provide adequate indication of pump performance and continue to provide an acceptable level of quality and safety.

Therefore, in accordance with 10 CFR 50.55a(z)(2) Byron Station requests relief from the specific ISTB requirements identified in this request.

6. Duration of Proposed Alternative The proposed alternative will be utilized during the entire fourth 120-month Inservice Test interval (which will begin on July 1, 2016 and conclude on June 30, 2026).

7. Precedents This relief request was previously approved for the third 120-month Interval at Byron Station as relief request RP-1. That approval was documented in NRC SER dated September 7, 2006, TAC NOS. MC9642, MC9643, MC9752, MC9753, MC9754, MC9755, MC9758, MC9759, MC9764 and MC9765.

Response to Request for Additional Information Regarding Relief Request RP-1 Associated with the Fourth Inservice Testing Interval

References:

(1) Letter from D. M. Gullott (Exelon Generation Company, LLC) to U. S. NRC, "Submittal of Relief Requests Associated with the Fourth Inservice Testing Interval," dated June 22, 2015 (2) Email form J. Wiebe (NRC) to J. A. Bauer (Exelon Generation Company, LLC), "Preliminary RAls for Relief Request RP-1," dated October 15, 2015 In the Reference 1, Exelon Generation Company, LLC (EGC) requested approval of five proposed relief requests in accordance with 10 CFR 50.55a, "Codes and standards." These relief requests are associated with the Fourth 10-Year Inservice Testing (IST) Program Interval for Byron Station. The Fourth 10-Year Interval begins on July 1, 2016 and is required by 10 CFR 50.55a(f)(4) to comply with the requirements of the American Society of Mechanical Engineers (ASME) Operation and Maintenance (OM) Code, 2004 Edition through the 2006 Addenda.

In Reference 2, the NRC requested additional information related to Relief Request RP-1 which addresses the Essential Service Water Makeup Pumps' vibration limits. It was agreed that the response to the request for additional information would be submitted to the NRC on or before November 30, 2015. The subject response is presented in Attachment 1.

As noted in Reference 1, the Byron Station Fourth 10-year IST Interval will be in effect from July 1, 2016 to June 30, 2026; accordingly, EGC respectfully requests approval of the subject relief requests by June 22, 2016.

November 30, 2015 U. S. Nuclear Regulatory Commission Page 2 There are no regulatory commitments contained in this letter. Should you have any questions concerning this letter, please contact Joseph A. Bauer at (630) 657-2804.

Respectfully, David M. Gullott Manager Licensing Exelon Generation Company, LLC : Response to Request for Additional Information Related to Relief Request RP-1 cc: NRC Regional Administrator Region III NRC Senior Resident Inspector Byron Station NRC Project Manager, NRR Byron Station Illinois Emergency Management Agency Division of Nuclear Safety

ATTACHMENT 1 Response to Request for Additional Information Related to Relief Request RP-1 In the Reference 1, Exelon Generation Company, LLC (EGC) requested approval of five proposed relief requests in accordance with 10 CFR 50.55a, "Codes and standards." These relief requests are associated with the Fourth 10-Year Inservice Testing (IST) Program Interval for Byron Station. The Fourth 10-Year Interval begins on July 1, 2016 and is required by 10 CFR 50.55a(f)(4) to comply with the requirements of the American Society of Mechanical Engineers (ASME) Operation and Maintenance (OM) Code, 2004 Edition through the 2006 Addenda.

In Reference 2, the NRC requested additional information related to Relief Request RP-1 which addresses the Essential Service Water Makeup Pumps' vibration limits. The response to the NRC's request is presented below.

RAI-RP-1-1 Provide vibration history from 2001 to present and history of maintenance activities performed or corrective actions taken (if any) since 2001.

Response

Based on a clarification call with the NRC on October 29, 2015, it was agreed that providing vibration and maintenance history data from July 2006; i.e., the start of the Third Inservice Testing Interval, to present would be acceptable. The subject vibration data is provided in Attachment 1-1, and the maintenance history is provided in Attachment 1-2.

RAI-RP-1-2 ASME OM Code, paragraph ISTB-5223(d) requires, in part, that "vibration (displacement or velocity) shall be determined and compared with corresponding reference values. Vibration measurements are to be broad band (unfiltered). If velocity measurements are used, they shall be peak. "

However, in the letter dated March 1, 2001 from Philadelphia Gear Corporation (PGC) to EGC, PGC stated, in part, that the recommended maximum levels of filtered housing vibration in terms of velocity is 0.3 inch per second (ips). It appears that the PGC recommended ALERT RANGE of 0.55 ips was based on filtered vibration measurements. Therefore, it is not clear if filtered vibration measurements are used in the Byron IS program.

Provide confirmation that in the Byron 1ST program, the proposed gearbox vibration value of 0.55 inch per second is unfiltered and peak, as required by the ASME OM Code, IS TB-5223(d).

Response

Exelon confirms that the proposed gearbox vibration value of 0.55 inch per second is unfiltered and peak, as required by Maintenance procedures MA-AA-716-230-1005, "AMS Suite:

Machinery Health Manager Database Setup Guideline," and MA-AA-716-230-1008, "Setup and Operation of CSI 2130 Handheld Vibration Monitoring Equipment Using AMS Suite: Machinery Health Manager and the Standalone Data Transfer Software." The vibration data is collected

ATTACHMENT 1 Response to Request for Additional Information Related to Relief Request RP-1 using Byron Operating procedure OBOSR 5.5.8.SX.5-1(2)c, "Unit Zero Comprehensive Inservice Testing (IST) Requirements For Essential Service Water Makeup Pump OA(B)."

RAI-RP-1-3 RP-1 is requested under 10 CFR 50.55a(z)(1). This alternative request should be requested under 10 CFR 50.55a(z)(2), because compliance with the ASME OM Code requirements would result in increased test frequency which may be considered as hardship to the licensee.

Provide details of the hardship associated with increased test frequency such as increased man-hours and dose (if any).

Response

Exelon concurs that Relief Request RP-1 will be requested in accordance with 10 CFR 50.55a(z)(2), "Hardship without a compensating increase in quality and safety." In summary, placing the SX Makeup pumps in double test frequency due to their normal vibration levels would result in 7040 additional man hours, increased pump run time/pump component degradation, confined space entry hazards and inclement weather executions over the Fourth 10-year IST Interval. A revised copy of Relief Request RP-1 is provided in Attachment 1-3.

This revision of RP-1 replaces the previous revision of Relief Request RP-1 submitted in Reference 1 in its entirety.

RAI-RP-1-4 The spectral analysis has been performed as part of the second and third ten year IST program. However, RP-1 did not specifically reference spectral analysis. Performing spectral analysis enhances the ability of monitoring and detecting pump degradations.

Provide reasons or rationales for not addressing or not performing spectral analysis in the fourth 10-year 1ST program.

Response

Spectral analysis will be performed on SX Makeup Pump vibration data throughout the Fourth IST Interval. Future advanced analysis techniques, equivalent to spectral analysis, may be performed in lieu of spectral analysis.

1. ASME Code Component(s) Affected OSX02PA Essential Service Water Makeup Pump A OSX02PB Essential Service Water Makeup Pump B

2. Applicable Code Edition and Addenda

ASME OM Code 2004 Edition through the 2006 Addenda.

3. Applicable Code Requirement

Table ISTB-5221-1, "Vertical Line Shaft and Centrifugal Pumps Test Acceptance Criteria."

4. Reason for Request

In accordance with 10 CFR 50.55a, "Codes and standards," paragraph (z)(2), relief is requested from the requirement of ASME OM Code Table ISTB-5221-1. The basis of the relief request is that the Code requirements present an undue hardship without a compensating increase in the level of quality and safety. Table ISTB-5221-1 specifies the vibration limits for vertical line shaft pumps operating at or above 600 rpm as the following for both the Group A and the comprehensive pump test:

Reference Value Acceptable Alert Required Action Vr < 2.5 Vr >2.5 Vr - 6.0 Vr or >6.OVr or

>0.325 - 0.70 in/sec >0.70 in/sec Due to the unique design of these pumps, normal vibration levels have been as high as approximately 0.5 in/sec at the gearbox locations. As a result, the normal vibration levels may exceed the Acceptable and Required Action limits of Table ISTB-5221-1.

5. Proposed Alternative and Basis for Use The objective of the essential service water (SX) make-up pump is to maintain cooling tower basin level to compensate for drift losses, evaporation, and blowdown. These pumps automatically start on a low level signal in the cooling tower basin. The pump will continue to operate regardless of whether offsite power is available or not since these pumps are diesel engine driven.

The essential service water make-up pumps are categorized as Group B since they are in a standby system which is not operated routinely except for testing.

ATTACHMENT 1-3 10 CFR 50.55a Request Number RP-1 Page 2 of 6 The SX Makeup Pumps are a unique design (see Figure 1). A horizontal diesel drives a right angle gearbox located approximately 39 feet above the pump. The driveshaft from the gearbox to the pump consists of five coupled sections and is located in the pump discharge piping column. Pump thrust is carried by bearings physically located within the gearbox. The pump is submerged in river water.

Although these pumps are considered vertical line shaft pumps, the unique design configuration is not addressed by the ASME OM Code. Due to monitoring limitations of this design, and because of the similarity to the requirements for vertical line shaft pumps, vibration is monitored on the gearbox. The limitation of taking the vibration readings at this location is that the resultant vibration readings are not attributable to the pump. Vibration analysis has indicated the vibration readings obtained are the result of vibration induced by the diesel engine and the gearbox itself, along with a resonant condition of the gearbox and its foundation.

Maintenance and inspection activities to date have indicated that the angle gearboxes have been operating properly and without degradation. Maintenance and inspection activities on the pumps have indicated that there has not been any pump degradation due to the vibration observed on the gearboxes. Likewise, the pump units have not caused vibration degradation of the gearboxes. As expected, since these pumps are Group B, little to any degradation has been identified.

The pump impellers have been replaced with stainless steel units and the wear rings replaced with a more resistant alloy, due to the adverse service application associated with these pumps. The new pump assemblies were tested at the vendor's facility and exhibited very low vibration levels.

Byron Station had consulted an industry vibration expert and vendor representative from the gearbox company in 2001 (see Figure 2), in an effort to ensure vibration levels are as low as achievable with this particular pump design, and to assure the existing vibration levels are not indicative of pump degradation. These efforts included the following activities:

Field service representatives from the gearbox company supervised the refurbishment of the two gearboxes. Both refurbished units were then installed on the pumps. The units that were refurbished had seen a significant amount of service under the historically higher vibration conditions and when inspected did not show any vibration related degradation.

Bi-directional support braces were installed on the gearboxes to address the vibration resonance problem.

The gearboxes were precision aligned and the couplings were balance checked upon installation.

All of these efforts combined have resulted in some reduction in the vibration levels; however, not enough to remove the pumps from the ASME OM Code Alert Range. Both pumps have experienced vibration levels at the gearbox locations of up to approximately

ATTACHMENT 1-3 10 CFR 50.55a Request Number RP-1 Page 3 of 6 0.5 in/sec during the third 10 year inservice testing interval. Byron has concluded that vibration levels recorded at the gearbox locations are normal for the unique design configuration and do not indicate an unusual condition of the gearbox or the pump. The proposed alternative limits below will ensure that required action is taken if vibration levels increase while ensuring the pump is not prematurely declared inoperable.

Since the gearbox normally exhibits relatively high vibration levels, which are not indicative of degradation, the use of Table ISTB-5221-1 would not be practical in that it would require double test frequency when the vibration levels are normal.

Placing the SX Makeup pumps in double test frequency with their normal vibration levels would result in 7,040 additional man hours, increased pump run time/pump component degradation, confined space entry hazards and inclement weather executions over the fourth 10-year IST interval.

Byron Station proposes the use of the following limits when performing vibration testing of the SX Makeup Pumps:

Reference Value Acceptable Alert Required Action Vr < 2.5 Vr or >2.5 Vr - 6.0 Vr or >6.OVr or

<_ 0.55 in/sec >0.55 0.70 in/sec >0.70 in/sec Increasing the Alert Range limits for these pumps would ensure that pumps are placed in double test frequency at a vibration level that would be abnormal for the SX Makeup Pumps' design configuration.

The basis of the >0.55 in/sec Alert limit was based on vendor concurrence and previous approval of this request during the third 10-year IST interval (See Figure 2 Vendor Concurrence Letters).

Using the provisions of this relief request as an alternative to the specific requirements of Table ISTB-5221-1 identified above will provide adequate indication of pump performance and continue to provide an acceptable level of quality and safety.

Therefore, in accordance with 10 CFR 50.55a(z)(2) Byron Station requests relief from the specific ISTB requirements identified in this request.

6. Duration of Proposed Alternative The proposed alternative will be utilized during the entire fourth 120-month Inservice Test interval (which will begin on July 1, 2016 and conclude on June 30, 2026).

7. Precedents This relief request was previously approved for the third 120-month Interval at Byron Station as relief request RP-1. That approval was documented in NRC SER dated September 7, 2006, TAC NOS. MC9642, MC9643, MC9752, MC9753, MC9754, MC9755, MC9758, MC9759, MC9764 and MC9765.
