NPF-72, AMENDMENT NO. 180 TO FACILITY OPERATING LICENSE NO. NPF-77, AMENDMENT NO. 186 TO FACILITY OPERATING LICENSE NO. NPF-37, AND AMENDMENT NO. 186 TO FACILITY OPERATING LICENSE NO. NPF-66

1.0 INTRODUCTION

EXELON GENERATION COMPANY, LLC BRAIDWOOD STATION, UNITS 1 AND 2 BYRON STATION, UNIT NOS. 1 AND 2 DOCKET NOS. STN 50-456, STN 50-457, STN 50-454, AND STN 50-455, By appiication to the U.S. Nuclear Regulatory Commission (NRC) dated April17, 2014 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML14111A257), Exelon Generation Company, LLC (the licensee) requested changes to the technical specifications (TSs) and facility operating licenses for the Braidwood Station (Braidwood), Units 1 and 2, and Byron Station (Byron), Unit Nos. 1 and 2. The proposed changes revise required action notes in the Braidwood and Byron TS 3.3.1 and TS 3.3.2 to reflect the specific functions that have bypass test capability installed and the specific functions that do not have bypass test capability installed. The current wording is no longer applicable because the installation and implementation of the bypass test instrumentation modifications for certain functions have been completed.

2.0 REGULATORY EVALUATION

The NRC staff determined that the licensee, in Section 4.1 of its submittal, identified the applicable regulatory requirements. The regulatory requirements for which the staff based its acceptance are as follows.

Enclosure Title 10 of the Code of Federal Regulations (1 0 CFR), Section 50.36(c)(2)(ii)(C) requires, in part, that a TS limiting condition for operation (LCO) be established for a structure, system, or component that is part of the primary success path and that functions or actuates to mitigate a design basis accident or transient that either assumes the failure of or presents a challenge to the integrity of a fission product barrier.

3.0 TECHNICAL EVALUATION

3.1 TS 3.3.1 Condition D Required Action Notes Current Text:

1. For Functions with installed bypass test capability, one channel may be bypassed for up to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> for surveillance testing and setpoint adjustment.
2. For Functions with no installed bypass test capability, the inoperable channel may be bypassed for up to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> for surveillance testing and setpoint adjustment of other channels.

Revised Text:

One channel may be bypassed for up to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> for surveillance testing and setpoint adjustment.

Evaluation The licensee in its March 14, 2011 (ADAMS Accession No. ML110760088), letter, identifies that Condition D applies to the Power Range Neutron Flux-High function.

The NRC staff by amendment dated April9, 2012 (ADAMS Accession No. ML120950371), approved installed bypass capability for Power Range Neutron Flux.

In its April17, 2014, submittal, the licensee states that Power Range Neutron Flux-High function has been modified to have installed bypass capability.

Based on the above NRC evaluation, the NRC staff determined that the wording regarding functions with no installed bypass test capability no longer applies and should be removed for clarification. The NRC staff, therefore, concludes that the revised text is consistent with the currently installed function capability and is acceptable.

Condition E Required Action Notes Current Text:

1. For Functions with installed bypass test capability, one channel may be bypassed for up to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> for surveillance testing and setpoint adjustment.
2. For Functions with no installed bypass test capability, the inoperable channel may be bypassed for up to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> for surveillance testing and setpoint adjustment of other channels.

Revised Text:

One channel may be bypassed for up to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> for surveillance testing and setpoint adjustment.

Evaluation The licensee in its April17, 2014, application, identified that ConditionE applies to the following functions:

Power Range Neutron Flux-Low; Overtemperature ~ T; Overpower ~T; Power Range Neutron Flux-High Positive Rate; and SG Water Level-Low Low.

The NRC staff by amendment dated April 9, 2012, approved installed bypass capability for the above listed functions. In its April 17, 2014, submittal, the licensee states that the above listed functions have been modified to have installed bypass capability.

Based on the above NRC evaluation, the NRC staff determined that the wording regarding functions with no installed bypass test capability no longer applies and should be removed for clarification. The NRC staff, therefore, concludes that the revised text is consistent with the currently installed function capability and is acceptable.

Condition K Required Action Notes Current Text:

1. For Functions with installed bypass test capability, one channel may be bypassed for up to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> for surveillance testing.
2. For Functions with no installed bypass test capability, the inoperable channel may be bypassed for up to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> for surveillance testing of other channels.

Revised Text:

1. For Functions with installed bypass test capability (Functions Sa, 9, and 1 0), one channel may be bypassed for up to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> for surveillance testing.
2. For Functions with no installed bypass test capability (Functions 12 and 13), the inoperable channel may be bypassed for up to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> for surveillance testing of other channels.

Evaluation The licensee in its April 17, 2014, application, identified that Condition K applies to the following functions:

o Function 8a o Function 9 o

Function 10 o

Function 12 o

Function 13 Pressurizer Pressure-Low Pressurizer Water Level - High Reactor Coolant Flow - Low Undervoltage Reactor Coolant Pumps Underfrequency Reactor Coolant Pumps The NRC staff by amendment dated April 9, 2012, approved installed bypass capability for:

Function 8a Function 9 Function 10 Pressurizer Pressure-Low Pressurizer Water Level - High Reactor Coolant Flow - Low In its April17, 2014, submittal, the licensee stated that the above three functions have been modified to have installed bypass capability. The revised text provides clarification wording to specify Functions 12 and 13.

Based on the above NRC evaluation, the NRC staff determines that the wording regarding functions with installed bypass test capability is applicable to Functions 8a, 9, and 10 and that the wording regarding the functions with no installed bypass test capability is applicable to Functions 12 and 13. The NRC staff, therefore, concludes that the revised text is consistent with the function capability and is acceptable.

3.2 TS 3.3.2 Condition D Required Action Notes Current Text:

1. For Functions with installed bypass test capability, one channel may be bypassed for up to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> for surveillance testing and setpoint adjustment.
2. For Functions with no installed bypass test capability, the inoperable channel may be bypassed for up to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> for surveillance testing and setpoint adjustment of other channels.

Revised Text:

One channel may be bypassed for up to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> for surveillance testing and setpoint adjustment.

Containment Pressure-High 1; Pressurizer Pressure-Low; Steam Line Pressure-Low; Containment Pressure-High 2; Steam Line Pressure-Negative Rate-High; SG Water Level-Low Low; and SG Water Level-High High (P-14).

The NRC staff by amendment dated April 9, 2012, approved installed bypass capability for the above functions. In its April17, 2014, submittal, the licensee stated that the above functions have been modified to have installed bypass capability.

Based on the above NRC evaluation, the NRC staff determined that the wording regarding functions with no installed bypass test capability no longer applies and should be removed for clarification. The NRC staff, therefore, concludes that the revised text is consistent with the currently installed function capability and is acceptable.

Condition K Required Action Notes Current Text:

1.

For Functions with installed bypass test capability, one channel may be bypassed for up to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> for surveillance testing.

2.

For Functions with no installed bypass test capability, the inoperable channel may be bypassed for up to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> for surveillance testing of other channels.

Revised Text:

One channel may be bypassed for up to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> for surveillance testing.

Evaluation The licensee in its March 14, 2011, letter, identifies that Condition K applies the Refueling Water Storage Tank Level-Low Low function. The NRC staff by amendment dated April9, 2012, approved installed bypass capability for the Refueling Water Storage Tank Level-Low Low function. In its April17, 2014, submittal, the licensee states that the Refueling Water Storage Tank Level-Low Low function has been modified to have installed bypass capability.

Based on the above NRC evaluation, the NRC staff determined that the wording regarding functions with no installed bypass test capability no longer applies and should be removed for clarification. The NRC staff, therefore, concludes that the revised text is consistent with the currently installed cuntion capability and is acceptable.

Based on the above, the NRC staff concludes that the TS revisions did not change LCOs, surveillances, or other TS requirements. The revisions removed text that was no longer applicable and inserted text to specifically identify TS required functions that have bypass test capability. Therefore the NRC staff concludes that the TSs with the requested revisions continue to meet 10 CFR 50.36(c)(2)(ii)(C) requirements.
