Subject:

License Amendment Request for Adoption of Technical Specifications Task Force (TSTF) Traveler TSTF-423, Revision 1, "Technical Specifications End States, NEDC-32988-A" 1.0 Description The proposed amendment will modify Technical Specifications (TS) to risk-inform requirements regarding selected Required Action end states. Additionally, it will modify the TS Required Actions with a Note prohibiting the use of limiting condition for operation (LCO) 3.0.4.a when entering the preferred end state (Mode 3) on reactor startup. The changes are consistent with Nuclear Regulatory Commission (NRC)-approved Technical Specification Task Force (TSTF) traveler TSTF-423, Revision 1, "Technical Specifications End States, NEDC-32988-A," dated December 22, 2009 (i.e., ADAMS Accession Number ML093570241) (Reference 1). The Federal Register notice published on February 18, 2011 (76 FR 34) (Reference 2) announced the availability of this TS improvement as part of the consolidated line item improvement process (CLllP).

2.0 Assessment 2.1 Applicability of Topical Report NEDC-32988-A, TSTF-423, and Model Safety Evaluation Duke Energy Progress, LLC, (Duke Energy) has reviewed Boiling Water Reactor (BWR)

Owners' Group (BWROG) topical report (TR) NEDC-32988-A (Reference 3), TSTF-423, Revision 1 (Reference 1), and the NRG staff's model safety evaluation (SE) (Reference 4) as part of the CLllP. Duke Energy has concluded that the information in TR NEDC-32988-A, TSTF-423, and the NRG staff's model SE are applicable to the Brunswick Steam Electric Plant (BSEP), Unit Nos. 1 and 2, and justify this license amendment request (LAR) for the incorporation of the changes to the BSEP TSs.

2.2 Optional Changes and Variations Duke Energy is proposing variations or deviations from TR NEDC-32988-A, the TS changes described in TSTF-423, Revision 1, or the NRG staff's model SE referenced in the Federal Register on February 18, 2011 (76 FR 34) as part of the CLllP Notice of Availability. The proposed variations/deviations and their effects are discussed in the following table.

Condition C addresses inoperability of a RHRSW for reasons other than Condition A.

BSEP TS 3.7.1 does not have a Condition equivalent to Standard TS 3.7.1 Condition B. Rather, BSEP TS 3.7.1 Condition B addresses inoperability of a RHRSW for reasons other than Condition A (i.e., which would include inoperability of one RHRSW pump in each subsystem). As such, adding the new BSEP TS 3.7.1 Condition C provides an equivalent change to that in TSTF 423 for Standard TS 3.7.1.

11. 3.7.2 Service Water No changes to BSEP The justification provided in (SW) System and TS 3.7.2 are proposed. the topical report and model Ultimate Heat Safety Evaluation for changes Sink (UHS) to Standard TS 3.7.2 are based on a typical two subsystem configuration. The BSEP SW system consists of four site nuclear service water pumps and three conventional service water pumps per plant. Based on the significant differences, no changes to BSEP TS 3.7.2 are proposed.

BSEP TS 3.7.3 addresses inoperability of one GREV subsystem (i.e., plant specific nomenclature corresponding to MCREC) in Condition A.

BSEP TS 3.7.3 Condition C provides the shutdown requirements for failure to meet the Completion Time of Condition A, Condition B, and for inoperability of two GREV subsystems. As such, only BSEP TS 3.7.3 Condition C is revised to provide equivalent changes to those in TSTF-423 for Standard TS 3.7.4.

3.0 Regulatory Analysis 3.1 No Significant Hazards Consideration Analysis Duke Energy has evaluated the proposed changes to the Technical Specifications (TS) using the criteria in 10 CFR 50.92 and has determined that the proposed changes do not involve a significant hazards consideration.

Description of Amendment Request: A change is proposed to the TS of the Brunswick Steam Electric Plant (BSEP), Units 1 and 2, consistent with TSTF-423, Revision 1, to allow, for some systems, entry into hot shutdown rather than cold shutdown to repair equipment, if risk is assessed and managed consistent with the program in place for complying with the

BSEP 16-0087 Enclosure 1 Page 9 of 11 requirements of 10 CFR 50.65(a)(4). Changes proposed in TSTF-423 will be made to the BSEP TSs for selected Required Action end states.

Basis for no significant hazards consideration determination: As required by 10 CFR 50.91 (a),

Duke Energy analysis of the issue of no significant hazards consideration is presented below:

1. Does the proposed change involve a significant increase in the probability or consequences of an accident previously evaluated?

Response: No The proposed change allows a change to certain required end states when the TS Completion Times for remaining in power operation will be exceeded. Most of the requested TS changes are to permit an end state of hot shutdown (Mode 3) rather than an end state of cold shutdown (Mode 4) contained in the current TS. The request was limited to: (1) those end states where entry into the shutdown mode is for a short interval, (2) entry is initiated by inoperability of a single train of equipment or a restriction on a plant operational parameter, unless otherwise stated in the applicable TS, and (3) the primary purpose is to correct the initiating condition and return to power operation as soon as is practical. Risk insights from both the qualitative and quantitative risk assessments were used in specific TS assessments. Such assessments are documented in Section 6 of topical report NEDC-32988-A, Revision 2, "Technical Justification to Support Risk-Informed Modification to Selected Required Action End States for BWR Plants." They provide an integrated discussion of deterministic and probabilistic issues, focusing on specific TSs, which are used to support the proposed TS end state and associated restrictions. The NRC staff finds that the risk insights support the conclusions of the specific TS assessments. Therefore, the probability of an accident previously evaluated is not significantly increased, if at all. The consequences of an accident after adopting TSTF-423 are no different than the consequences of an accident prior to adopting TSTF-423. Therefore, the consequences of an accident previously evaluated are not significantly affected by this change. The addition of a requirement to assess and manage the risk introduced by this change will further minimize possible concerns.

Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.

2. Does the proposed change create the possibility of a new or different kind of accident from any accident previously evaluated?

Response: No The proposed change does not involve a physical alteration of the plant (i.e., no new or different type of equipment will be installed). If risk is assessed and managed, allowing a change to certain required end states when the TS Completion Times for remaining in power operation are exceeded (i.e., entry into hot shutdown rather than cold shutdown to repair equipment) will not introduce new failure modes or effects and will not, in the absence of other unrelated failures, lead to an accident whose consequences exceed the consequences of accidents previously evaluated. The addition of a requirement to assess and manage the risk introduced by this change and the commitment by the

BSEP 16-0087 Enclosure 1 Page 10 of 11 licensee to adhere to the guidance in TSTF-IG-05-02, "Implementation Guidance for TSTF-423, Revision 1, 'Technical Specifications End States, NEDC-32988-A,'" will further minimize possible concerns.

Thus, based on the above, this change does not create the possibility of a new or different kind of accident from an accident previously evaluated.

3. Does the proposed change involve a significant reduction in a margin of safety?

Response: No The proposed change allows, for some systems, entry into hot shutdown rather than cold shutdown to repair equipment, if risk is assessed and managed. The BWROG's risk assessment approach is comprehensive and follows NRC staff guidance as documented in Regulatory Guides (RG) 1.174 and 1.177. In addition, the analyses show that the criteria of the three-tiered approach for allowing TS changes are met. The risk impact of the proposed TS changes was assessed following the three-tiered approach recommended in RG 1.177. A risk assessment was performed to justify the proposed TS changes. The net change to the margin of safety is insignificant.

Therefore, the proposed change does not involve a significant reduction in a margin of safety.

Based upon the reasoning presented above, Duke Energy concludes that the requested change involves no significant hazards consideration, as set forth in 10 CFR 50.92(c), "Issuance of Amendment."

3.2 Verifications, Commitments, and Additional Information Needed Duke Energy commits to the regulatory commitments in Enclosure 7. In addition, Duke Energy has proposed TS Bases consistent with TSTF-423, Revision 1, which provide guidance and details on how to implement the new requirements. Implementation of TSTF-423 requires that risk be managed and assessed, and the licensee's configuration risk management program is adequate to satisfy this requirement. The risk assessment need not be quantified, but may be a qualitative assessment of the vulnerability of systems and components when one or more systems are not able to perform their associated function. Finally, Duke Energy has a Bases Control Program consistent with Section 5.5 of the Standard Technical Specifications (STS).

4.0 Environmental Evaluation The proposed change would change a requirement with respect to installation or use of a facility c9mponent located \Nithin the restricted area, as defined in 10 CFR Part 20, and would change an inspection or surveillance requirement. However, the proposed change does not involve (i) a significant hazards consideration, (ii) a significant change in the types or significant increase in the amounts of any effluents that may be released offsite, or (iii) a significant increase in individual or cumulative occup2tional radiation exposure. Accordingly, the proposed change meets the eligibility criterion for categorical exclusion set forth in i O CFR 51.22(c)(9).

Therefore, pursuant to i O CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed change.

ECCS- Operating B 3.5.1 BASES ACTIONS C.1 and C.2 (continued)

If any Required Action and associated Completion Time of Condition A or B are not met, the plant must be brought to a MODE in which the LCO does not apply overall plant risk is minimized. To achieve this status , the plant must be brought to at least MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and to MODE 4 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.

Remaining in the Applicability of the LCO is acceptable because the plant risk in MODE 3 is similar to or lower than the risk in MODE 4 (Ref. 15) and because the time spent in MODE 3 to perform the necessarv repairs to restore the system to OPERABLE status will be short However.

voluntarv entry into MODE 4 may be made as it is also an acceptable low-risk state.

Required Action C, 1 is modified by a Note that states that LCO 3.0.4.a is not applicable when entering MODE 3. This Note prohibits the use of LCO 3.0.4.a to enter MODE 3 during startup with the LCO not met.

However. there is no restriction on the use of LCO 3.0.4.b. if applicable.

because LCO 3.0.4.b requires performance of a risk assessment addressing inoperable systems and components . consideration of the results determination of the acceptability of entering MODE 3 and establishment of risk management actions. if appropriate. LCO 3.0.4 is not applicable to, and the Note does not preclude, changes in MODES or other specified conditions in the Applicability that are required to comply with ACTIONS or that are part of a shutdown of the unit.

The allowed Completion Times--afe is._reasonable, based on operating experience , to reach the required plant conditions from full power conditions in an orderly manner and without challenging plant systems.

D.1 and D.2 If the HPCI System is inoperable and the RCIC System is verified to be OPERABLE, the HPCI System must be restored to OPERABLE status within 14 days. In this condition , adequate core cooling is ensured by the OPERABILITY of the redundant and diverse low pressure ECCS injection/spray subsystems in conjunction with ADS . Also , the RCIC System will automatically provide makeup water at most reactor operating pressures . Immediate verificati on of RCIC OPERABI LITY is th erefore required when HPCI is inoperable. This may be performed as an administrative check by examining logs or other information to determine if RCIC is out of service for maintenance or other reason s. It does not mean to perform the Surveillances needed to demonstrate the OPERABILITY of the RCIC System. However, if the OPERABILITY of the RCI C System cannot be immediately verified , Condition I must be immediately entered. If a sing le active component fails concu rrent with a design basis LOCA , there is a potential , depending on the specific fa ilu re, that th e minimum requ ired ECCS eq uipment wi ll not be availa ble.

A 14 day Completion Time is based on a reliability study cited in Brunswick Unit 1 B 3.5.1-7 Revision No. 31

ECCS-Operating B 3.5.1 BASES ACTIONS G.1 and G.2 (continued)

Since both a high pressure system (ADS) and a low pressure subsystem are inoperable, a more restrictive Completion Time of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> is required to restore either the low pressure ECCS subsystem or the required ADS valve to OPERABLE status. This Completion Time is based on a reliability study cited in Reference 12 and has been found to be acceptable through operating experience.

H.1 and H.2 If the HPCI System is inoperable in addition to one required ADS valve inoperable, adequate core cooling is ensured by the OPERABILITY of the remaining ADS valves and the low pressure ECCS subsystems.

However, overall ECCS reliability is reduced because a single active component failure concurrent with a design basis LOCA may result in the minimum required ECCS equipment not being available. Since a high pressure system is inoperable (HPCI) and the ADS cannot withstand a single active component failure , a more restrictive Completion Time of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> is required to restore either the HPCI System or the required ADS valve to OPERABLE status. The Completion Time is based on a reliability study cited in Reference 12 and has been found to be acceptable through operating experience.

1.1 and1.2 If any Required Action and associated Completion Time of Condition D, E, F, G, or H is not met, or if two or more required ADS *1alves are inoperable, the plant must be brought to a condition MODE in which--tRe LCO does not apply overall plant risk is minimized .

To achieve this status. the plant must be brought to at least MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and reactor steam dome pressure reduced to ::> 150 psig within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />. The allowed Completion Times are reasonable . based on operating experience . to reach the required plant conditions from full power conditions in an orderly manner and without challenging plant systems.

K1 When multiple ECCS subsystems are inoperable , as stated in Condition J!S, the plant is in a condition outside of the accident analyses.

Therefore , LCO 3.0 .3 must be entered immediately.

SURVEILLANCE SR 3.5.1.1 REQUIREMENTS The flow path piping of each ECCS has the potential to develop voids and pockets of entrained air. Maintaining the pump discharge lines of the HPCI System , CS subsystems , and LPCI subsystems full of water ensures that the ECCS w ill perform properly, injecting its full capacity into the RCS upon demand . This SR also prevents water hammer in the piping following an ECCS initiation signal. One acceptable method of ensuring that the lines are full is to vent at the high points. The 31 day Frequency is based on the gradual nature of void buildup in the ECCS piping , the procedural controls governing system operation , and operating experience .

SR 3.5.1.2 Verifying the correct alignment for manual , power operated , and automatic valves in the ECCS flow paths provides assurance that the proper flow paths exist for ECCS operation . This SR does not apply to valves that are locked , sealed , or otherwise secu red in position since these are verified to be in the correct position prior to locking , sealing , or securing . A valve that receives an initiation signal is allowed to be in a nonaccident position provided the valve will automatically reposition to the accident position in the proper stroke time. This SR does not require any testing or valve manipulation ; rather, it involves verification th at those valves capable of potentially bein g mispositioned are in the correct position . This SR does not apply to valves that cannot be inadvertently misaligned , such as check valves. For the HPCI System, this SR al so includes the steam flow path for the tu rbine and the flow contro ller position.

REQUIREMENTS TIME testing. This exception is allowed since the ECCS instrumentation response time is a small part of the ECCS RESPONSE TIME (e .g.,

sufficient margin exists in the emergency diesel generator start time when compared to the instrumentation response time) (Ref. 14).

ECCS RESPONSE TIME tests are conducted every 24 months. The 24 month Frequency is consistent with the Brunswick refueling cycle.

RCIC System B 3.5.3 BASES ACTIONS A.1 and A.2 (continued)

OPERABLE status within 14 days. In this condition , loss of the RCIC System will not affect the overall plant capability to provide makeup inventory at high reactor pressure since the HPCI System is available to function during a loss of coolant accident (LOCA) . OPERABILITY of the HPCI System is therefore verified immediately when the RCIC System is inoperable. This may be performed as an administrative check, by examining logs or other information, to determine if the HPCI System is out of service for maintenance or other reasons. It does not mean it is necessary to perform the Surveillances needed to demonstrate the OPERABILITY of the HPCI System. If the OPERABILITY of the HPCI System cannot be immediately verified , however, Condition B must be immediately entered . For transients and certain abnormal events with no LOCA, RCIC (as opposed to HPCI) is the preferred source of makeup coolant because of its relatively small capacity, which allows easier control of the RPV water level. Therefore, a limited time is allowed to restore the inoperable RCIC to OPERABLE status .

The 14 day Completion Time is based on the availability of the HPCI System and the low probability of the occurrence of an event that would require the RCIC System.

B.1 and B.2 If the RCIC System cannot be restored to OPERABLE status within the associated Completion Time , or if the HPCI System is simultaneously inoperable, the plant must be brought to a condition in which the LCO does not apply overall plant risk is minimized. To achieve this status, the plant must be brought to at least MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and reactor steam dome pressure reduced to < 150 psig within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.

Remaining in the Applicability of the LCO is acceptable because the plant risk in MODE 3 is similar to or lower than the risk in MODE 4 <Ref. 4) and because the time spent in MODE 3 to perform the necessarv repairs to restore the system to OPERABLE status will be short. However, voluntarv entrv into MODE 4 may be made as it is also an acceptable low-risk state.

Required Action B.1 is modified by a Note that states that LCO 3.0.4.a is not applicable when entering MODE 3. This Note prohibits the use of LCO 3.0.4.a to enter MODE 3 during startup with the LCO not met.

However, there is no restriction on th e use of LCO 3.0.4.b, if applicable ,

because LCO 3.0.4.b requires performance of a risk assessment addressing inoperable systems and components, cons ideration of the results, determination of the acceptability of entering MODE 3, and establishment of risk management actions , if appropriate. LCO 3.0.4 is not applicable to, and the Note does not preclude, changes in MODES or other specified conditions in the Applicability that are required to comply with ACTIONS or that are part of a shutdown of the unit.

.B...1 If a required suppression chamber-to-drvwell vacuum breaker is inoperable for opening and is not restored to OPERABLE status within the required Completion Time. the plant must be brought to a condition in which overall plant risk is minimized . To achieve this status. the plant must be brought to at least MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

Remaining in the Applicabilitv of the LCO is acceptable because the plant risk in MODE 3 is similar to or lower than the risk in MODE 4 (Ref. 3) and because the time spent in MODE 3 to perform the necessary repairs to restore the system to OPERABLE status will be short. However.

Required Action B.1 is modified by a Note that states that LCO 3.0.4.a is not applicable when entering MODE 3 This Note prohibits the use of LCO 3.0.4.a to enter MODE 3 during startup with the LCO not met.

However there is no restriction on the use of LCO 3.0.4.b. if applicable because LCO 3 O 4 b requires performance of a risk assessment addressing inoperable systems and components. consideration of the results. determination of the acceptabilitv of entering MODE 3. and establishment of risk management actions if appropriate.

The 14 day Frequency is based on engineering judgment, is considered adequate in view of other indications of vacuum breaker status available to operations personnel and procedural controls to ensure the drywell is normally maintained at a higher pressure than the suppression chamber, and has been shown to be acceptable through operating experience . This verification is also required within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> after any discharge of steam to the suppression chamber from any source, and within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> after an operation that causes any of the vacuum breakers to open.

A Note is added to this SR which allows suppression chamber-to-drywell vacuum breakers opened in conjunction with the performance of a Surveillance to not be considered as failing this SR. These periods of opening vacuum breakers are controlled by plant procedures and do not represent inoperable vacuum breakers.

SR 3.6 .1.6.2 Each required vacuum breaker must be cycled to ensure that it opens adequately to perform its design function and returns to the fully closed position. This is accomplished by verifying each required vacuum breaker operates through at least one complete cycle of full travel. This SR ensures that the safety analysis assumptions are valid. The 92 day Frequency of this SR was developed , based on lnservice Testing Program requirements to perform valve testing at least once every 92 days. In addition , this functional test is required within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> after a discharge of steam to the suppression chamber fro m the SRVs.

SR 3.6.1.6.3 Verification of the vacuum breaker opening setpoint is necessary to ensure that the safety analysis assumption regarding vacuum breaker full open differential pressure of 0.5 psid is valid. The 24 month Frequency is based on the need to perform this Surveillance under the conditions that apply during a plant outage and the potential for an unplanned transient if the Surveillance were performed with the reactor at power.

B.1 and B.2 If secondary containment cannot be restored to OPERABLE status within the required Completion Time, the plant must be brought to a MODE in which the LCO does not apply overall plant risk is minimized . To achieve this status , the plant must be brought to at least MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and to MODE 4 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.

Remaining in the Applicability of the LCO is acceptable because the plant risk in MODE 3 is similar to or lower than the risk in MODE 4 (Ref. 7),

because the time spent in MODE 3 to perform the necessary repairs to restore the system to OPERABLE status will be short. However, voluntary entry into MODE 4 may be made as it is also an acceptable low-risk state.

Required Action B.1 is modified by a Note that states that LCO 3.0.4.a is not applicable when entering MODE 3. This Note prohibits the use of LCO 3.0.4.a to enter MODE 3 during startup with the LCO not met.

However there is no restriction on the use of LCO 3.0.4.b, if applicable .

because LCO 3.0 4,b requires performance of a risk assessment addressing inoperable systems and components. consideration of the results. determination of the acceptability of entering MODE 3, and establishment of risk management actions . if appropriate.

The allowed Completion Times afe--is_reasonable , based on operating experience, to reach the required plant conditions from full power conditions in an orderly manner and without challenging plant systems.

C.1 and C.2 Movement of recently irradiated fuel assemblies in the secondary containment and OPDRVs can be postulated to cause significant fission product release to the secondary containment. In such cases, the secondary containment is the only barrier to release of fission products to the environ ment. Therefore, movement of recently irradiated fu el assemblies must be immediately suspended if the secondary containment is inoperable. Suspension of this activity shall not preclude completing an action that involves moving a component to a safe position. Also, acti on must be immediately in itiated to suspend OPDRVs to minimize the probability of a vessel draindown and subsequent potential for fission produ ct release. Action s must continue until OPDRVs are suspended .

LCO 3.0.3 is not applicable wh ile in MODE 4 or 5. However, since recently irradiated fuel assembly movement can occur in MODE 1, 2, or 3, Required Action C.1 has been mod ified by a Note stating that Brunswick Unit 1 B 3.6.4.1 -3 Revision No. 31

SGT System B 3.6.4 .3 BASES APPLICABILITY (OPDRVs) or during movement of recently irradiated fuel assemblies in (continued) the secondary containment. Due to radioactive decay, the SGT System is only required to be OPERABLE during fuel handling accidents involving handling recently irradiated fuel (i.e., fuel that has occupied part of a critical reactor core within the previous 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />).

ACTIONS A.1 With one SGT subsystem inoperable in MODE 1, 2, or 3, the inoperable subsystem must be restored to OPERABLE status in 7 days. In this condition , the remaining OPERABLE SGT subsystem is adequate to perform the required radioactivity release control function. However, the overall system reliability is reduced because a single failure in the OPERABLE subsystem could result in the radioactivity release control function not being adequately performed. The 7 day Completion Time is based on consideration of such factors as the availability of the OPERABLE redundant SGT subsystem and the low probability of a OBA occurring during this period.

B.1 and B.2 In MODE 1, 2, or 3, if one SGT subsystem cannot be restored to OPERABLE status within the required Completion Time or both SGT subsystems are inoperable, the plant must be brought to a MODE in which the LCO does not apply overall plant risk is minimized . To achieve this status, the plant must be brought to at least MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and to MODE 4 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.

Remaining in the Applicability of the LCO is acceptable because the plant risk in MODE 3 is similar to or lower than the risk in MODE 4 (Ref. 8) and because the time spent in MODE 3 to perform the necessary repairs to restore the system to OPERABLE status will be short. However.

voluntary entry into MODE 4 may be made as it is also an acceptable low-risk state, Required Action B.1 is modified by a Note that states that LCO 3.0.4.a is not applicable when entering MODE 3. This Note prohibits the use of LCO 3.0.4 .a to enter MODE 3 during startup with the LCO not met.

However, there is no restriction on the use of LCO 3.0.4.b, if applicable.

because LCO 3.0.4.b requ ires performance of a risk assessment addressing inoperable systems and components , considerati on of the results. determination of the acceptability of entering MODE 3. and establishment of risk man agement actions if appropriate . LCO 3.0.4 is not applicable to . and the Note does not preclude changes in MODES or other specified con ditions in the Applicabil ity that are requ ired to comply with ACTIONS or that are part of a shutdown of the unit.

The allowed Completion Times are-is_reasonable, based on operating experience, to reach the required plant conditions from full power conditions in an orderly manner and without challenging plant systems.

SGT System B 3.6.4.3 BASES SURVEILLANCE SR 3.6.4.3.2 REQUIREMENTS (continued) This SR verifies that the required SGT filter testing is performed in accordance with the Ventilation Filter Testing Program (VFTP) . The SGT System filter tests are in accordance with Regulatory Guide 1.52 (Ref. 6) ,

except as specified in Specification 5.5.7, "Ventilation Filter Testing Program (VFTP)". The VFTP includes testing HEPA filter performance, charcoal adsorber efficiency, minimum system flow rate, and the physical properties of the activated charcoal (general use and following specific operations). It is noted that, per the basis provided by ESR 99-00055 (Ref. 7) , system flow rate is determined using installed calibrated flow orifice plates. Specific test frequencies and additional information are discussed in detail in the VFTP .

SR 3.6.4.3.3 This SR verifies that each SGT subsystem starts on receipt of an actual or simulated initiation signal. While this Surveillance can be performed with the reactor at power, operating experience has demonstrated that these components will usually pass the Surveillance when performed at the 24 month Frequency. The LOGIC SYSTEM FUNCTIONAL TEST in LCO 3.3.6.2, "Secondary Containment Isolation Instrumentation ,"

overlaps this SR to provide complete testing of the safety function .

Therefore, the Frequency was found to be acceptable from a reliability standpoint.

RHRSW System B 3.7.1 BASES ACTIONS (continued)

Required Action B.1 is intended to handle the inoperability of one RHRSW subsystem for reasons other than Condition A. The Completion Time of 7 days is allowed to restore the RHRSW subsystem to OPERABLE status. With the unit in this condition , the remaining OPERABLE RHRSW subsystem is adequate to perform the RHRSW heat removal function. However, the overall reliability is reduced because a single failure in the OPERABLE RHRSW subsystem could result in loss of RHRSW function . The 7 day Completion Time is based on the Completion Time provided for the RHR suppression pool cooling function ,

the redundant RHRSW capabilities afforded by the OPERABLE subsystem, and the low probability of an event occurring requiring RHRSW during this period.

A Note to the Required Action indicates that the applicable Conditions of LCO 3.4.7, be entered and Required Actions taken if the inoperable RHRSW subsystem results in inoperable RHR shutdown cooling . This is an exception to LCO 3.0.6 and ensures the proper actions are taken for these components .

C.1 If one RHRSW subsystem is inoperable or one RHRSW pump in one or one subsystem is inoperable and not restored within the provided Completion Times. the plant must be brought to a condition in which overall plant risk is minimized . To achieve this status . the plant must be brought to at least MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

This is an exception to LCO 3.0.6 and ensures the proper actions are taken for these components .

D.1 and D.2E .1 and E.2 If the RHRSW subsystems cannot be not restored to OPERABLE status within the associated Completion Times, the unit must be placed in a MODE in which the LCO does not apply. To achieve this status , the unit must be placed in at least MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and in MODE 4 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.

RHRSW System B 3.7.1 BASES (continued)

SURVEILLANCE SR 3.7.1.1 REQUIREMENTS Verifying the correct alignment for each manual , power operated , and automatic valve in each RHRSW subsystem flow path provides assurance that the proper flow paths exist for RHRSW operation. This SR does not apply to valves that are locked , sealed , or otherwise secured in position , since these valves are verified to be in the correct position prior to locking , sealing , or securing . A valve is also allowed to be in the nonaccident position , and yet considered in the correct position , provided it can be realigned to its accident position. This is acceptable because the RHRSW System is a manually initiated system .

This SR does not require any testing or valve manipulation; rather, it involves verification that those valves capable of being mispositioned are in the correct position. This SR does not apply to valves that cannot be inadvertently misaligned , such as check valves.

The 31 day Frequency is based on engineering judgment, is consistent with the procedural controls governing valve operation , and ensures correct valve positions.

D.1. D.2.1 . D.2 .2. and D.2.3 The Required Actions of Condition D are modified by a Note indicating that LCO 3.0.3 does not apply. If moving irradiated fuel assemblies while in MODE 1, 2, or 3, the fuel movement is independent of reactor operations. Therefore, inabil ity to suspend movement of irradiated fuel assemblies is not sufficient reason to require a reactor shutdown .

During movement of irradiated fuel assemblies in the secondary containment, during CORE ALTERATIONS , or during OPDRVs, if the inoperable CREV subsystem cannot be restored to OPERABLE status within the required Completion Time , the OPE RABLE CREV subsystem may be placed in the radiation/smoke protection mode. This action ensures that the remaining subsystem is OPERABLE , that no fail ures that would prevent automatic actuation will occur, and th at any active fai lu re will be readily detected.

Control Room AC System B 3.7.4 BASES (continued)

ACTIONS A.1 With one control room AC subsystem inoperable, the inoperable control room AC subsystem must be restored to OPERABLE status within 30 days. With the unit in this condition , the remaining OPERABLE control room AC subsystems are adequate to perform the control room air conditioning function. However, the overall reliability is reduced because a single failure in the OPERABLE subsystems could result in loss of the control room air conditioning function. The 30 day Completion Time is based on the low probability of an event occurring requiring control room isolation , the consideration that the remaining subsystems can provide the required protection , and the availability of alternate safety and nonsafety cooling methods.

B.1 With two control room AC subsystems inoperable, the Control Room AC System may not be capable of performing the intended function .

However, since the BNP control room is common to both Units 1 and 2, the risk associated with continued operation for a relatively short time could be less than that associated with an immediate controlled shutdown of both units. Therefore, additional time is allowed to restore one of the inoperable control room AC subsystems to OPERABLE status. The 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> Completion Time provides a period of time to correct the problem commensurate with the importance of maintaining the Control Room AC System OPERABLE . This time period also ensures that the probability of an accident (requiring Control Room AC System OPERABILITY) occurring during periods when two control room AC subsystems are inoperable is minimal.

C.1 and C.2 In MODE 1, 2, or 3, if Required Action A.1 or B.1 cannot be completed within the associated Completion Time, the unit must be placed in a MODE that minimizes overall plant risk. To achieve this status , the unit must be placed in at least MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and in MODE 4 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.

Remaining in the Applicability ofthe LCO is acceptable because the plant risk in MODE 3 is similar to or lower than the risk in MODE 4 (Ref. 3) and because the time spent in MODE 3 to perform the necessary repairs to restore the system to OPERABLE status will be short. However.

However, since irradiated fuel assembly movement can occur in MODE 1, 2, or 3, the Required Actions of Condition D are modified by a Note indicating that LCO 3.0.3 does not apply. If moving irradiated fuel assemblies while in MODE 1, 2, or 3, the fuel movement is independent of reactor operations.

Therefore, inability to suspend movement of irradiated fuel assemblies is not sufficient reason to require a reactor shutdown.

During movement of irradiated fuel assemblies in the secondary containment, during CORE ALTERATIONS , or during OPDRVs, if Required Action A.1 or B.1 cannot be completed within the associated Completion Time , the OPERABLE control room AC subsystem or subsystems may be placed immediately in operation . This action ensures that the remaining subsystem(s) is OPERABLE, that no failures that would prevent actuation will occur, and that any active failure will be readily detected .

An alternative to Required Action D.1 is to immediately suspend activities that present a potential for releasing radioactivity that might require isolation of the control room . This places the unit in a condition that minimizes risk.

If applicable, CORE ALTERATIONS and movement of irradiated fuel assemblies in the secondary containment must be suspended immediately. Suspension of these activities shall not preclude completion of movement of a component to a safe position. Also , if applicable , action must be initiated immediately to suspend OPDRVs to minimize the probability of a vessel draindown and subsequent potential for fission product release . Action must continue until the OPDRVs are suspended .

E.1 If three control room AC subsystems are inoperable in MODE 1, 2, or 3, the Control Room AC System may not be capable of performing the intended function . Theref.ore , LCO 3.0 .3 must be entered immediately.

If moving irradiated fuel assemblies while in MODE 1, 2, or 3, the fuel movement is independent of reactor operations .

Therefore, inability to suspend movement of irradiated fuel assemblies is not a sufficient reason to require a reactor shutdown .

Main Condenser Offgas B 3.7.5 BASES (continued)

LCO To ensure compliance with the assumptions of the Main Condenser Offgas System failure event (Ref. 1), the fission product release rate should be consistent with a noble gas release to the reactor coolant of 100 µCi/MWt-second after decay of 30 minutes. The LCO is established consistent with this requirement (2436 MWt x 100 µCi/MWt-second =

243 ,600 µCi/second) and is based on the original licensed RATED THERMAL POWER.

APPLICABILITY The LCO is applicable when steam is being exhausted to the main condenser and the resulting noncondensibles are being processed via the Main Condenser Offgas System. This occurs during MODE 1, and during MODES 2 and 3 with any main steam line not isolated and the SJAE in operation. In MODES 4 and 5, main steam is not being exhausted to the main condenser and the requirements are not applicable.

ACTIONS A.1 If the offgas radioactivity rate limit is exceeded , 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> is allowed to restore the gross gamma activity rate to within the limit. The 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> Completion Time is reasonable, based on engineering judgment, the time required to complete the Required Action , the large margins associated with permissible dose and exposure limits, and the low probability of a Main Condenser Offgas System failure.

B.1. B.2. and B.3.1. and B.3.2 If the gross gamma activity rate is not restored to within the limits in the associated Completion Time , all main steam lines or the SJAE must be isolated . This isolates the Main Condenser Offgas System from significant sources of radioactive steam. The main steam lines are considered isolated if at least one main steam isolation valve in each main steam line is closed , and at least one main steam line drain valve in each drain line is closed. The 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> Completion Time is reasonable ,

An alternative to Required Actions B.1 and B.2 is to place the unit in a MODE in which the LCO does not apply overall plant risk is minimized .

To achieve this status, the unit must be placed in at least MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and in MODE 4 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.

Remaining in the Applicability of the LCO is acceptable because the plant risk in MOPE 3 is similar to or lower than the risk in MODE 4 <Ref. 4) and because the time spent in MODE 3 to pertorm the necessary repairs to restore the system to OPERABLE status will be short. However.

voluntarv entry into MODE 4 may be made as it is also an acceptable low-risk state .

Required Action B.3 is modified by a Note that states that LCO 3.0.4.a is not applicable when entering MODE 3. This Note prohibits the use of LCO 3.0.4.a to enter MODE 3 during startup with the LCO not met.

However, there is no restriction on the use of LCO 3.0.4 .b. if applicable ,

SURVEILLANCE SR 3.7 .5.1 REQUIREMENTS This SR, on a 31 day Frequency, requires an isotopic analysis of an offgas sample (taken at the discharge of the main condenser air ejector prior to dilution or discharge) to ensure that the required limits are satisfied . The noble gases to be sampled are Xe-133, Xe-135 , Xe-138 ,

Kr-85m , Kr-87 , and Kr-88. If the measured rate of radioactivity increases significantly (by~ 50% after correcting for expected increases due to changes in THERMAL POWER) , an isotopic analysis is also performed within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> after the increase is indicated (by the condenser air ejector noble gas activity monitor) , to ensure that the increase is not indicative of a sustained increase in the radioactivity rate. The 31 day Frequency is adequate in view of other instrumentation that continuously monitor the offgas , and is acceptable , based on operating experience .

This SR is modified by a Note indicating that the SR is not required to be performed until 31 days after any main steam line is not isolated and the SJAE is in operation. Only in this condition can radioactive fission gases be in the Main Condenser Offgas System at significant rates.

AC Sources-Operating B 3.8.1 BASES ACTIONS G.1 (continued)

According to Regulatory Guide 1.93 (Ref. 9) , with two or more DGs inoperable, operation may continue for a period that should not exceed 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />. While this Action allows more than two DGs to be inoperable, Regulatory Guide 1.93 (Ref. 9) assumes only two DGs are required by the LCO , and a loss of those two DGs results in a total loss of on site power to the Class 1E Electrical Power Distribution System. Thus, with the BNP electrical design , a loss of the four DGs results in the same condition assumed in Regulatory Guide 1.93 (Ref. 9).

H.1 and H.2 If the inoperable AC electrical power sources cannot be restored to OPERABLE status within the associated Completion Time, the unit must be brought to a MODE in which the LCO does not apply overall plant risk is minimized. To achieve this status, the unit must be brought to at least MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and to MODE 4 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.

Remaining in the Applicability of the LCO is acceptable because the plant risk in MODE 3 is similar to or lower than the risk in MODE 4 (Ref. 14) and because the time spent in MODE 3 to perform the necessarv repai rs to restore the system to OPERABLE status will be short. However.

voluntarv entry into MODE 4 may be made as it is also an acceptable low-risk state .

Required Action H 1 is modified by a Note that states that LCO 3,0.4 ,a is not applicable when entering MODE 3. This Note prohibits the use of LCO 3.0.4 ,a to enter MODE 3 during startup with the LCO not met.

However. there is no restriction on the use of LCO 3.0.4.b, if applicable ,

because LCO 3.0.4.b requires performance of a risk assessment addressing inoperable systems and components. consideration of the results. determination of the acceptability of entering MODE 3, and establishment of risk management actions . if appropriate. LCO 3.0.4 is not applicable to. and the Note does not preclude, changes in MODES or other specified conditions in the Applicability that are required to comply with ACTIONS or that are part of a shutdown of the unit.

The allowed Completion Times afe-is_reasonable , based on operating experience , to reach the required plant conditions from full power conditions in an orderly manner and without challenging plant systems .

L1 Condition I corresponds to a level of degradation in which all redundan cy in the AC electrical power supplies has been lost. At thi s severely deg raded level, any further losses in the AC electrical power system may cau se a loss of function. Therefore, no additional time is justified for continued operation . The unit is required by LCO 3.0.3 to commence a controlled shutdown.

DC Sources-Operating B 3.8.4 BASES ACTIONS A.1 (continued)

Therefore.the Required Actions of Condition A are modified by a Note to indicate that when Condition A results in de-energization of an AC electrical power distribution subsystem or a DC electrical power distribution subsystem , Actions of LCO 3.8 .7 must be immediately entered . This allows Condition A to provide requirements for the loss of a DC electrical power subsystem without regard to whether a distribution subsystem is de-energized. LCO 3.8.7 provides the appropriate restriction for a de-energized distribution subsystem.

Condition A represents one division with a loss of ability to completely respond to an event, and a potential loss of ability to remain energized during normal operation. It is therefore imperative that the operator's attention focus on stabilizing the unit, minimizing the potential for complete loss of DC power to the affected division .

If one of the required DC electrical power subsystems is inoperable (e.g .,

inoperable battery, inoperable battery charger(s), or inoperable battery charger and associated inoperable battery) , the remaining DC electrical power subsystems have the capacity to support a safe shutdown and to mitigate an accident condition. Since a subsequent worst case single failure could , however, result in the loss of minimum necessary DC electrical subsystems to mitigate a worst case accident, continued power operation should not exceed 7 days. The Completion time is based on the capacity and capability of the remaining DC Sources, including the enhanced reliability afforded by the capability to manually transfer DC loads to the opposite unit's DC electrical power distribution subsystems .

B.1 and B.2 If the DC electrical power subsystem cannot be restored to OPERABLE status within the required Completion Time or if two or more DC electrical power subsystems are inoperable , the unit must be brought to a MODE in which the LCO does not apply overall plant risk is minimized . To achieve this status, the unit must be brought to at least MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and to MODE 4 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.

Remaining in the Appl icability of the LCO is acceptable because the plant risk in MODE 3 is similar to or lower than the risk in MODE 4 (Ref. 12) and because the time spent in MODE 3 to perform the necessarv repairs to restore the system to OPERABLE status will be short. However, voluntarv entry into MODE 4 may be made as it is also an accepta ble low-risk state, Required Action B.1 is mod ified by a Note that states that LCO 3.0.4.a is not appl icable when entering MODE 3. This Note prohibits th e use of LCO 3.0.4.a to enter MODE 3 during startup with the LCO not met.

However, th ere is no restriction on the use of LCO 3.0.4.b, if applicable because LCO 3.0.4 .b req uires performance of a risk assessment addressing inoperable systems and components, consideration of the results, determination of the acceptability of entering MODE 3, and Brunswick Un it 1 B 3.8.4-4 Revision No. 31

The Completion Time to bring the unit to MODE 4 is consistent with the time required in Regulatory Guide 1.93 (Ref. 7) .

C 1andC2 If two or more DC electrical power subsystem are inoperable, the unit must be brought to a MODE in which overall plant risk is minimized. To achieve this status , the unit must be brought to a MODE in which the LCO does not apply. To achieve this status, the unit must be brought to at least MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and to MODE 4 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.

The Completion Time to bring the unit to MODE 4 is consistent with the time required in Regulatorv Guide 1.93 <Ref. 7) .

SURVEILLANCE SR 3.8.4.1 REQUIREMENTS Verifying battery terminal voltage while on float charge for the batteries helps to ensure the effectiveness of the charging system and the ability of the batteries to perform their intended function . Float charge is the condition in which the charger is supplying the continuous charge required to overcome the internal losses of a battery and maintain the battery in a fu lly charged state. The voltage requirements are based on the nominal design voltage of the battery. The 7 day Frequency is conservative when compared with manufacturer recommendations and IEEE-450 (Ref. 8).

SR 3.8.4.2 Visual inspection to detect corrosion of the battery cells and connections ,

or measurement of the resistance of each inter-cell and inter-rack connection , provides an indication of physical damage or abnormal deterioration that could potentially degrade battery performance.

The connection resistance limits are ::; 1.2 times the established benchmark resistance values for the connections or ::; 5µohms above the established benchmark resistance values for the connections, which ever is higher. These connection resistance acceptance criteri a were derived from IEEE-450 (Ref. 8) and IEEE-484 (Ref. 9) , respectively.

The Frequency for these inspections, which can detect conditions that can cause power losses due to resistance heating, is 92 days. This Frequency is consistent with man ufacturers recommendations.

This Completion Time allows for an exception to the normal "time zero" for beginning the allowed outage time "clock."

To achieve this status, the plant must be brought to at least MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and to MODE 4 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.

Distribution Systems-Operating B 3.8.7 BASES (continued)

SURVEILLANCE SR 3.8.7.1 REQUIREMENTS Th is Surveillance verifies that the AC and DC electrical power distribution systems are functioning properly , with the correct circuit breaker alignment. This includes verifying that distribution bus tie breakers are open and control power transfer switches associated with the 4.16 kV and 480 V emergency buses and transfer switches associated with the ESS and DG panels are aligned to their normal DC sources . The correct breaker alignment ensures the appropriate separation and independence of the electrical buses are maintained , and power is available to each required bus. The verification of energization of the buses ensures that the required power is readily available for motive as well as control functions for critical system loads connected to these buses . This may be performed by verification of absence of low voltage alarms or by verifying a load powered from the bus is operating. The 7 day Frequency takes into account the redundant capability of the AC and DC electrical power distribution subsystems, and other indications available in the control room that alert the operator to subsystem malfunctions .

SR 3.8.7.2 This Surveillance verifies that no combination of more than two power conversion modules (consisting of either two lighting inverters or one lighting inverter and one plant uninterruptible power supply unit) are aligned to Division II (bus B). Two power conversion modules aligned to Division II (bus B) was an initial assumption in the DC battery load study.

Limiting two power conversion modules to be aligned to Division II ensures the associated batteries will supply DC power to safety related equipment during a design basis event. The 7 day Frequency takes into account the redundant capability of the DC electrical power distribution subsystems and indications available in the control room to alert the operator of power conversion module misalignment.
