Attachment 1 GNRO-2007/00009 Description and Assessment to GNRO-2007/00009 Page 1 of 4 1.O DESCRIPTION The proposed amendment would modify the Grand Gulf Nuclear Station (GGNS) Technical Specifications (is) requirements for Mode change limitations in LCO 3.0.4 and SR 3.0.4.

The GGNS TS already contain a TS Bases Control Program (TS 5.5.1 1) and SR 3.0.1, thus these requirements do not need to be added as described in NRC-approved Industry Technical Specification Task Force (TSTF) Standard Technical Specification Change, TSTF-359, Rev. 9, Increase Flexibility in MODE Restraints.

The proposed TS changes are consistent with Nuclear Regulatory Commission (NRC) approved Industry Technical Specification Task Force (TSTF) Standard TS (STS) change, TSTF-359, Revision 8, as modified by the notice in the Federal Register; published on April 4, 2003 (68 FR 16579). That Federal Register Notice (FRN) announced the availability of this TS improvement through the Consolidated Line Item Improvement Process (CLIIP).

TSTF-359, Revision 8 was subsequently revised to incorporate the modifications discussed in the April 4,2003, FRN and other minor changes. TSTF-359, Revision 9 was subsequently submitted to the NRC on April 28,2003 and was approved by the NRC on May 9,2003.

2.0 ASSESSMENT 2.1 ADDlicabilitv of Published Safetv Evaluation Entergy Operations, Inc. (EOI) has reviewed the safety evaluation published on April 4, 2003 (68 FR 16579) as part of the CLIIP Notice of Availability. This verification included a review of the NRC staffs safety evaluation, as well as the supporting information provided to support TSTF-359, Rev. 9. EOI has concluded that the justifications presented in the TSTF proposal and the safety evaluation prepared by the NRC staff are applicable to GGNS and justify this amendment for the incorporation of the changes to the GGNS TS.

2.2 Optional Chanqes and Variations EOI is adopting the TS changes described in TSTF-359, Revision 9, and the NRC staffs model safety evaluation published on April 4, 2003, with the following exceptions.

1. Due to differences between the GGNS TS and TS Bases and their corresponding model BWW6 STS (NUREG-1434), in some cases variances from the TSTF marked-up changes are made. These variances are discussed below and do not affect the adoption or application of TSTF-359, Revision 9.
a. In the TSTF mark-ups, BWW6 STS 3.6.3.1, Primary Containment Hydrogen Recombiners, the NOTE LCO 3.0.4 is not applicable, was removed from REQUIRED ACTION A. The GGNS equivalent TS was deleted per TS Amendment 166, issued in NRC letter dated June 16,2004. Therefore, GGNS TS 3.6.3.1 markups are not included in this package.

2. TS Section 1.4 Frequency

Description:

Section 1.4, Frequency, Example 1.4-1, is revised to be consistent with the changes to SR 3.0.4. SR 3.0.4 was revised by TSTF- 359, Revision 9, and the current example is not consistent with the Technical Specification requirements. The second paragraph of Example 1.4-1 is revised to reflect the changes made to SR 3.0.4.

Justification: The changes made in TSTF 359 to SR 3.0.4 have made certain statements in Example 1.4-1 incorrect. This change is consistent with TSTF-485, Rev. 0.

Table 1 of this attachment provides a brief summary of the changes.

3.0 REGULATORY ANALYSIS

3.1 No Siqnificant Hazards Consideration Determination EOI has reviewed the proposed no significant hazards consideration determination published on April 4, 2003 (68 FR 16579) as part of the CLIIP. EOI has concluded that the proposed determination presented in the notice is applicable to GGNS and the determination is hereby incorporated by reference to satisfy the requirements of 10 CFR 50.91 (a).

3.2 Verification and Commitments As discussed in the notice of availability published in the Federal Register on April 4, 2003 (68 FR 16579) for this TS improvement, the following plant-specific verifications were performed as follows:

EOI has proposed changes to the TS Bases for LCO 3.0.4 and SR 3.0.4 which state that use of the TS mode change limitation flexibility established by LCO 3.0.4 and SR 3.0.4 is not to be interpreted as endorsing the failure to exercise the good practice of restoring systems or components to operable status before entering an associated MODE or other specified condition in the TS Applicability.

The proposed changes also include changes to the Bases for LCO 3.0.4 and SR 3.0.4 that provide details on how to implement the new requirements. The Bases changes provide guidance for changing Modes or other specified conditions in the Applicability when an LCO is not met. The Bases changes describe in detail how: LCO 3.0.4.a allows entry into a MODE or other specified condition in the Applicability with the LCO not met when the associated ACTIONS to be entered permit continued operation in the MODE or other specified condition in the Applicability for an unlimited period of time; LCO 3.0.4.b allows entry into a MODE or other specified condition in the Applicability with the LCO not met after performance of a risk assessment addressing inoperable systems and components, consideration of the results, determination of the acceptability of entering the MODE or other specified condition in the Applicability, and establishment of risk management actions, if appropriate; and LCO 3.0.4.c allows entry into a MODE or other specified condition in the Applicability with the LCO not met to GNRO-2007/00009 Page 3 of 4 based on a Note in the Specification, which is typically applied to Specifications which describe values and parameters (e.g., RCS Specific Activity) though it may be applied to other Specifications based on NRC plant-specific approval. The Bases also state that any risk impact should be managed through the program in place to implement 10 CFR 50.65(a)(4) and its implementation guidance, NRC Regulatory Guide 1.182, Assessing and Managing Risk Before Maintenance Activities at Nuclear Power Plants, and that the results of the risk assessment shall be considered in determining the acceptability of entering the MODE or other specified condition in the Applicability, and any corresponding risk management actions.

Upon entry into a MODE or other specified condition in the Applicability with the LCO not met, LCO 3.0.1 and LCO 3.0.2 require entry into the applicable Conditions and Required Actions until the Condition is resolved, until the LCO is met, or until the unit is not within the Applicability of the Technical Specification. The Bases also state that SR 3.0.4 does not restrict changing MODES or other specified conditions of the Applicability when a Surveillance has not been performed within the specified Frequency, provided the requirement to declare the LCO not met has been delayed in accordance with SR 3.0.3.

Finally, as noted in Section 1.O above, the GGNS TS already contain a TS Bases Control Program (TS 5.5.1 1) and SR 3.0.1 , thus these requirements do not need to be added to the TS.

4.0 ENVIRONMENTAL EVALUATION EOI has reviewed the environmental evaluation included in the model safety evaluation published on April 4,2003 (68 FR 16579) as part of the CLIIP. EOI has concluded that the staffs findings presented in that evaluation are applicable to GGNS and the evaluation is hereby incorporated by reference for this application.

If any one low pressure ECCS injection/spray subsystem is inoperable, the inoperable subsystem must be restored to OPERABLE status within 7 days. In this Condition, the remaining OPERABLE subsystems provide adequate core cool ing during a LOCA. However, overall ECCS reliability i s reduced because a single failure in one of the remaining OPERABLE subsystems concurrent with a LOCA may result in the ECCS not being able to perfom its intended safety function. The 7 day Completion Time i s based on a reliability study (Ref. 12) that evaluated the impact on ECCS availability by assuming that various components and subsystems were taken out of service. The results were used to calculate the average availability of ECCS equipment needed to mitigate the consequences of a LOCA as a function o f allowed outage times (i.e., Completion Times).

8.1 and 8.Z If the HPCS System i s inoperable, and the RCIC System is verified to be OPERABLE (when RCIC is required to be OPERABLE), the HPCS System must be restored to OPERABLE status within 14 days. In this Condition, adequate core cooling i s ensured by the OPERABILITY o f the redundant and diverse low pressure ECCS injection/spray subsystems in conjunction wjth the ADS. Also, the RCIC System will automatically provide makeup water at most reactor operating pressures.

This may be performed by an administrative check, by examining logs or other information, to determine if RCIC is out o f service for maintenance or other reasons. It is not necessary to perform the Surveillances needed to demonstrate the OPERABILITY o f the RCIC System. However, if the OPERABILITY of the RCIC System cannot be verified and RCIC i s required to be OPERABLE, Condition D must be i m d i a t e l y entered. If a single active component fails concurrent with a design basis LOCA, there i s a potential, depending on the specific failure, that the minimum required ECCS equipment will not be available. A 14 day Completion Time i s based on the results o f a reliability study (Ref. 12) and has been found to be acceptable through operating experience.

GRAND GULF B 3.5-6 Revision No. 8 to GNRO-2007/00009 Page 13 of 22 RCIC System B 3.5.3 BASES BACKGROUND The RCIC pump i s provided with a minimum flow bypass line, (continued) which discharges to the suppression pool. The valve in this line automatically opens to prevent pump damage due to overheating when other discharge line valves are closed. To ensure rapid delivery of water to the RPV and to minimize water h a m e r effects, the RCIC System discharge llne "keep fill" system is designed to maintain the pump discharge line filled with water.

APPLICABLE The function of the RCIC System is to respond to transient SAFETY ANALYSES events by providing makeup coolant to the reactor. The RCIC System is not an Engineered Safety Feature System and no credit is taken in the safety analyses for RClC System operation. Based on its contribution to the reduction of overall plant risk, however, the system is included in the Technical Specifications as required by the NRC Policy Stat ement .

LCO The OPERABILITY of the RCIC System provides adequate core cooling such that actuation o f any o f the ECCS subsystems i s not required in the event of RPV isolation accompanied by a loss o f feedwater f l o w . The RCIC System has sufficient capacity to maintain RPV inventory during an isolation event. t i APPLICABILITY The RCIC System i s required to be OPERABLE in MODE 1, and MODES 2 and 3 with reactor steam dome pressure > 150 psig since RCIC i s the primary non-ECCS water source for 'core cooling when the reactor is Isolated and pressurized. In MOOES 2 and 3 with reactor steam dome pressure 5 150 psig, and in HODES 4 and 5, RCIC is not required t o be OPERABLE since the ECCS injection/spray subsystems can provide sufficient flow to the vessel.

ACTIOEIS /%.I and A . Z If the RCIC System is inoperable during MODE 1, or MODES 2 or 3 with reactor steam dome pressure > 150 psig, and the HPCS System is verified to be OPERABLE, the RCIC System must be restored to 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 (cont inuedl GRAND GULF B 3.5-22 Revision NO.^

APPLICABILITY In MODES 1 and 2, the hydrogen igniter is required to control hydrogen concentration to near the fl anmabil ity limit of 4.0 v/o following a degraded core event that would generate hydrogen i n amounts equivalent to a metal water reaction o f 75% o f the core cladding. The control of hydrogen concentration prevents overpressurization of the primary containment. The event that could generate hydrogen in quantities sufficiently high enough to exceed the flamability limit is limited to MODES 1 and 2.

In MODE 3, both the hydrogen production rate and the total hydrogen produced after a degraded core accident would be less than that calculated for the DBA L O U . Also, because of the limited t i w in this WE, the probability o f an accident requiring the hydrogen igniter is low, Therefore, the hydrogen igniter is not requlred in HODE 3.

In W E S 4 and 5, the probability and consequences of a degraded core accident are reduced due to the pressure and temperature 1 imitations. Therefore, the hydrogen igniters are not required to be OPERABLE in W E S 4 and 5 to control hydrogen.

ACTIONS -

A. 1 With one hydrogen igniter division inoperable, the inoperable division must be restored to OPERABLE status within 30 days. In this Conditfon, the remaining OPERABLE hydrogen igniter division is adequate to perform the hydrogen burn function. However, the overall reliability i s reduced because a single failure in the OPERABLE subsystem could result i n reduced hydrogen control capabil ity. The 30 day Completion Time is based on the low probability o f the occurrence o f a degraded core event that would generate hydrogen in amounts equivalent to a metal water reaction of 75% of the core cladding, the amount o f time available after the event for operator action to prevent hydrogen accufaulation from exceeding the flamsability limit, and the low probability of failure of the OPERABLE hydrogen igniter GRAND GULF B 3.6-74 Revision N 0 .

The verification may be performed as an administrative check by examining logs or other information to determine the availability of the a1 ternate hydrogen control capabi 1 it ies. It does not mean to perform the Surveillances needed to demonstrate OPERABILITY of the a1 ternate hydrogen control capabilities.

If the ability to perform the hydrogen control function i s maintained, continued operation i s permitted with two igniter divisions inoperable for up to 7 days. Seven days is a reasonable time to allow two igniter divisions to be inoperable because the hydrogen control function i s maintained and because of the lw probability of tho occurrence of a LOCA that would generate hydrogen in the a u n t s capable of exceeding the flamability limit.

c.1 If any Required Action and required Completion Time cannot be met, the plant must be brought to a HODE in which the K O does not apply.

ACTIONS To ensure a highly reliable power source remains, it is necessary to verify the availability of the remaining required offsite circuits on a more frequent basis. Since the Required Action only specifies "perform," a failure of SR 3.8.1.1 acceptance criteria does not result in the Required Action not met. However, if a second required circuit fails SR 3.8.1.1, the second offsite circuit i s inoperable, and Condition C, for two offsite circuits inoperable, is entered.

This Completion Time assumes sufficient offsite power remains to power the minimum loads needed to respond to analyzed events. In the event more than one division i s without offsite power, this assumption is not met.

Therefore, the optional Completion Time is specifled.

With one offsite circuit inoperable, the reliability of the offsite system i s degraded, and the potential for a loss of offsite p e e r is increased, with attendant potential for a challenge to the plant safety systems. In this Conditlon, however, the remaining OPERABLE offsite circuit and DGs are adequate to supply electrical power to the onsite Class 1 E distribution system.

The Completion Time takes into account the capacity and capability of the remaining AC sources, reasonable time for repairs, and the low probability of a DBA occurring during this period.

to GNRO-2007/00009 Page 18 of 22 INSERT 1B (LCO 3.0.4 BASES)

LCO 3.0.4 establishes limitations on changes in MODES or other specified conditions in the Applicability when an LCO is not met. It allows placing the unit in a MODE or other specified condition stated in that Applicability (e.g., the Applicability desired to be entered) when unit conditions are such that the requirements of the LCO would not be met, in accordance with LCO 3.0.4.a, LCO 3.0.4.b, or LCO 3.0.4.c.

LCO 3.0.4.a allows entry into a MODE or other specified condition in the Applicability with the LCO not met when the associated ACTIONS to be entered permit continued operation in the MODE or other specified condition in the Applicability for an unlimited period of time.

Compliance with Required Actions that permit continued operation of the unit for an unlimited period of time in a MODE or other specified condition provides an acceptable level of safkty for continued operation. This is without regard to the status of the unit befbre or after the MODE change. Therefbre, in such cases, entry into a MODE or other specified condition in the Applicability may be made in accordance with the provisions of the Required Actions.

LCO 3.0.4.b allows entry into a MODE or other specified condition in the Applicabilitywith the LCO not met aRer performance of a risk assessment addressing inoperable systems and components, considerationof the results, determinationof the acceptabilityof entering the MODE or other specified condition in the Applicability, and establishment of risk management actions, if appropriate.

The risk assessment may use quantitative, qualitative, or blended approaches, and the risk assessment will be conducted using the plant program, procedures, and criteria in place to implement 10 CFR 50.65(a)(4), which requires that risk impacts of maintenance activities to be assessed and managed. The risk assessment, for the purposes of LCO 3.0.4 (b), must take into account all inoperable Technical Specification equipment regardless of whether the equipment is included in the normal 10 CFR 50.65(a)(4) risk assessment scope. The risk assessments will be conducted using the procedures and guidance endorsed by Regulatory Guide 1.182, Assessing and Managing Risk Before Maintenance Activities at Nuclear Power Plants. Regulatory Guide 1.182 endorses the guidance in Section I 1 of NUMARC 93-01, Industry Guideline for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants. These documents address general guidance fix conduct of the risk assessment, quantitative and qualitative guidelines for establishing risk management actions, and example risk management actions.

These include actions to plan and conduct other activities in a manner that controls overall risk, increased risk awareness by shift and management personnel, actions to reduce the duration of the condition, actions to minimize the magnitude of risk increases (establishment of backup success paths or compensatory measures), and determination that the proposed MODE change is acceptable. Considerationshould also be given to the probability of completing restoration such that the requirements of the LCO would be met prior to the expiration of ACTIONS Completion Times that would require exiting the Applicability.

LCO 3.0.4.b may be used with single, or multiple systems and components unavailable. NUMARC 93-01 provides guidance relative to consideration of simultaneous unavailability of multiple systems and components.

to GNRO-2007/00009 Page 19 of 22 The results of the risk assessment shall be considered in determining the acceptability of entering the MODE or other specified condition in the Applicability, and any corresponding risk management actions. The LCO 3.0.4.b risk assessments do not have to be documented.

The Technical Specificationsallow continued operation with equipment unavailable in MODE 1 for the duration of the Completion Time. Since this is allowable, and since in general the risk impact in that particular MODE bounds the risk of transitioning into and through the applicable MODES or other specified conditions in the Applicability of the LCO, the use of the LCO 3.0.4.b allowance should be generally acceptable, as long as the risk is assessed and managed as stated above. However, there is a small subset of systems and components that have been determined to be more important to risk and use of the LCO 3.0.4.b allowance is prohibited.

The LCOs governing these system and components contam Notes prohi3iting the use of LCO 3.0.4.b by stating that LCO 3.0.4.b is not applicable.

LCO 3.0.4.c allows entry into a MODE or other specified condition in the Applicability with the LCO not met based on a Note m the Specificationwhich states LCO 3.0.4.c is applicable.

These specific allowances permit entry into MODES or other specified conditions in the Applicability when the associated ACTIONS to be entered do not provide for continued operation for an unlimited period of time and a risk assessment has not been performed. This allowance may apply to all the ACTIONS or to a specific Required Action of a Specification.

The risk assessments performed to just@ the use of LCO 3.0.4.b usually only consider systems and components. For this reason, LCO 3.0.4.c is typically applied to Specificationswhich describe values and parameters (e.g., RCS Specific Activity), and may be applied to other Specifications based on NRC plant-specific approval.

The provisions of this Specification should not be interpreted as endorsing the M u e to exercise the good practice of restoring systems or components to OPERABLE status before entering an associated MODE or other specified condition in the Applicability.

The provisions of LCO 3.0.4 shall not prevent changes in MODES or other specified conditions in the Applicability that are required to comply with ACTIONS. In addition, the provisions of LCO 3.0.4 shall not prevent changes in MODES or other specified conditions in the Applicability that result from any unit shutdown. In this context, a unit shutdown is defined as a change in MODE or other specil5ed condition in the Applicability associated with transitioning fiom MODE 1 to MODE 2, MODE 2 to MODE 3, and MODE 3 to MODE 4.

Upon entry into a MODE or other specified condition in the Applicability with the LCO not met, LCO 3.0.1 and LCO 3.0.2 require entry into the applicable Conditions and Required Actions until the Condition is resolved, until the LCO is met, or until the unit is not within the Applicability of the Technical Specification.

Surveillances do not have to be performed on the associated inoperable equipment (or on variables outside the specified limits), as permitted by SR 3.0.1. Therefore, utilizing LCO 3.0.4 is not a violation of SR 3.0.1 or SR 3.0.4 for any Surveillances that have not been performed on to GNRO-2007/00009 Page 20 of 22 inoperable equipment. However, SRs must be met to ensure OPERABILITY prior to declaring the associated equipment OPERABLE (or variable within limits) and restoring compliance with the affected LCO.

INSERT 2B (SR 3.0.4 BASES)

SR 3.0.4establishes the requirement that all applicable SRs must be met befbre entry into a MODE or other specified condition in the Applicability.

This Specificationensures that system and component OPERABILITY requirements and variable limits are met before entry into MODES or other specified conditions in the Applicability for which these systems and components ensure safe operation of the unit. The provisions of this Specification should not be interpreted as endorsing the fhilure to exercise the good practice of restoring systems or components to OPERABLE status before entering an associated MODE or other specified condition in the Applicability.

A provision is included to allow entry into a MODE or other specified condition in the Applicability when an LCO is not met due to Surveillance not being met in accordance with LCO 3.0.4.

However, in certain circumstances, failing to meet an SR will not result in SR 3.0.4 restricting a MODE change or other specified condition change. When a system, subsystem, division, component, device, or variable is inoperable or outside its specified limits, the associated SR(s) are not required to be performed, per SR 3.0.1, which states that surveillances do not have to be performed on inoperable equipment. When equipment is inoperable, SR 3.0.4 does not apply to the associated SR(s) since the requirement for the SR(s) to be performed is removed Therefbre, &dug to perform the Surveillance(s) within the specified Frequency does not result in an SR 3.0.4restriction to changing MODES or other specified conditions of the Applicability.

However, since the LCO is not met in this instance, LCO 3.0.4will govern any restrictions that may (or may not) apply to MODE or other specified condition changes. SR 3.0.4does not restrict changing MODES or other specified conditions of the Applicability when a Surveillance has not been performed within the specified Frequency, provided the requirement to declare the LCO not met has been delayed in accordance with SR 3.0.3.

The provisions of SR 3.0.4 shall not prevent entry into MODES or other specified conditions in the Applicability that are required to comply with ACTIONS. In addition, the provisions of SR 3.0.4 shall not prevent changes in MODES or other specified conditions in the Applicability that result &om any unit shutdown In this context, a unit shutdown is defined as a change in MODE or other specified condition in the Applicability associated with transitioning fiom MODE 1 to MODE 2, MODE 2 to MODE 3, and MODE 3 to MODE 4.

The precise requirements for performance of SRs are specified such that exceptions to SR 3.0.4 are not necessary. The specific time frames and conditions necessary for meeting the SRs are specified in the Frequency, in the Surveillance, or both. This allows performance of to GNRO-2007/00009 Page 21 of 22 Surveillances when the prerequisite condition(s) specified in a Surveillance procedure require entry into the MODE or other specified condition in the Applicabilityof the associated LCO prior to the performance or completion of a Surveillance. A Surveillance that could not be performed until after entering the LCO's Applicability, would have its Frequency specified such that it is not "due" until the specific conditions needed are met. Alternately, the Surveillance may be stated in the form of a Note, as not required (to be met or performed) until a particular event, condition, or time has been reached Further discussion of the specific formats of SRs' annotation is found in Section 1.4, Frequency.
