SUMMARY
The proposed amendment would modify the Perry Nuclear Power Plant (PNPP) Technical Specification (TS) requirements for mode change limitations in Limiting Condition for Operation (LCO) 3.0.4 and Surveillance Requirement (SR) 3.0.4.
The changes are consistent with Technical Specification Task Force (TSTF) change TSTF-359, Revision 9, entitled Increase Flexibility in MODE Restraints". A notice of opportunity to comment on a Model Safety Evaluation, Environmental Consideration, and a No Significant Hazards Consideration for this change to LCO 3.0.4 and SR 3.0.4 was published in the Federal Register on August 2, 2002, as part of the Consolidated Line Item Improvement Process (CLIIP). Resolution of comments on the published CLIIP, and a notice of availability of this TS improvement were published in the Federal Register (FR) on April 4, 2003. This FR Notice referred to a "modified Revision 8" of the TSTF.
Subsequently Revision 9 of TSTF-359 was Issued to resolve changes to Revision 8. These resolutions were agreed to by the Nuclear Regulatory Commission (NRC) staff, and Revision 9 has been listed on the NRC CLIIP web site as being equivalent to the "modified Revision 8" discussed in the April 4, 2003 Federal Register notice (the changes made in Rev. 9 are publicly available and explained at the NRC web site, -at the following location:
http://www.nrc.covlreactors/operatina/licensina/techspecs/techspecs-pdf/359r9.pdf).
DESCRIPTION OF THE CHANGES As noted above, the proposed amendment would modify various TS requirements for mode change limitations in LCO 3.0.4 and SR 3.0.4. The proposed TS changes which directly adopt TSTF-359 Revision 9 with no variations are described directly below. A subsequent discussion entitled
'Optional Changes and Variations" describes the TS changes where variances are required from TSTF-359 Revision 9.
Descrintion Of TS Chanaes Which Directly Adopt Revision 9 Of TSTF-359
- 1. LCO 3.0.4 is revised to allow entry into a MODE or other specified condition in the Applicability while relying on the associated ACTIONS, provided one of the following is met:
- a. 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;
- b. 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; exceptions to this Specification are stated in the individual Specifications; or
- c. When an allowance is stated in the individual value, parameter, or other Specification.
- 2. SR 3.0.4 is revised to reflect the concepts of the change to LCO 3.0.4, including clarifying the relationship between SR 3.0.4, SR 3.0.3 and LCO 3.0.4.
Attachment 2 PY-CEI/NRR-2772L Page 2 of 4
- 3. The applicability of LCO 3.0.4 and SR 3.0.4 is expanded to include transition into all MODES or other specified conditions in the Applicability, except those transitions that are required to comply with ACTIONS, or that are part of a shutdown of the unit.
- 4. The following LCOs are revised to include a new NOTE to indicate that the risk assessment provisions of item 3.0.4.b (see above) may not be utilized for the diesel generators (DGs) and for the High Pressure Core Spray (HPCS) and Reactor Core Isolation Cooling (RCIC) systems:
> LCO 3.5.1 "ECCS-Operating"
> LCO 3.5.3 *RCIC System"
> LCO 3.8.1 UAC Sources - Operating'
- 5. As directed by TSTF-359, all of the existing "exceptions" to LCO 3.0.4 which currently exist in a number of Specifications are deleted. Based on the rewording of LCO 3.0.4, these NOTES, which state OLCO 3.0.4 is not applicable", are no longer needed or appropriate.
Optional Technical Snecification Changes and Variations All of the changes to the Technical Specifications described in the NRC staff's Model Safety Evaluation dated April 4, 2003 (as modified by the NRC approved Revision 9 of TSTF-359) and those described in the text of TSTF-359 Revision 9 have been included without change or variation.
TSTF-359 also contains marked up Specification pages, and one minor difference from the BWR-6 markups is necessary due to a plant-specific difference in PNPP LCO 3.4.7 as compared to the Standard Technical Specification (STS) LCO 3.4.7. The PNPP LCO 3.4.7 contains two exceptions to LCO 3.0.4 which need to be deleted, whereas the STS LCO 3.4.7 contains only one such exception.
One additional clarification is made to be consistent with the changes being incorporated into SR 3.0.4. This change Is made In the Examples provided in TS Section 1.4 "Frequency'. Section 1.4 explains how to apply the surveillance testing rules. Two of the Examples discuss what constitutes a "violation" of SR 3.0.4; these are being clarified to acknowledge the existence of the two exceptions contained within SR 3.0.4. Specifically, this change to the Examples clarifies that MODE changes may be completed under the provisions of SR 3.0.3 or LCO 3.0.4 without "violating" SR 3.0.4. This ensures consistency between the newly revised SR 3.0.4 and the Section 1.4 Examples.
Bases With respect to the model Bases included InTSTF-359, only two minor clarifications to the Bases discussions are being made (the Bases markups are provided in Attachment 4, for information, as they are not a formal part of the Technical Specifications - changes to the Bases are completed under the provisions of the PNPP Bases Control Program):
- In two places in the model Bases (for LCO 3.0.4 and for SR 3.0.4), a definition is provided for what constitutes a "shutdown", as described in these two Specifications. In both places, the model Bases sentence states 'in this context, a unit shutdown is defined as a change in MODE
... from MODE I to MODE 2, MODE 2 to MODE 3, and MODE 3 to MODE 4." This "definition" does not address a common Boiling Water Reactor (BWR) shutdown path, involving a manual scram of the plant (where the plant goes from MODE 1 into MODE 3). This "definition" in the Bases could theoretically be interpreted to require that LCO 3.0.4 and SR 3.0.4 need to be applied to shutdowns by scram, which Is not the case. Therefore, these Bases sentences are revised to address this type of shutdown from MODE I to MODE 3. No technical information was removed by this change, and the intent of the discussion is retained.
-S ,
Attachment 2 PY-CEI/NRR-2772L Page 3 of 4
- The reworded SR 3.0.4 contains two clarifications of its interrelationship with SR 3.0.3 and LCO 3.0.4. In the model TSTF-359 Bases, the discussions of these two exceptions are out of order, i.e., in TS SR 3.0.4 itself, the exception addressing SR 3.0.3 comes before the exception addressing LCO 3.0.4, but in the model Bases, the SR 3.0.3 exception discussion was added after the discussion of the LCO 3.0.4 exception. Since the resultant discussion in the model Bases is confusing, the PNPP Bases markups were rearranged in the correct order, and an introductory sentence was added which provides a lead-in to the discussion of the two exceptions. No technical information was removed by this reformatting, and the intent of the discussions are retained.
TECHNICAL ANALYSIS Applicability of the Published Model Safety Evaluation A review has been performed which compared the PNPP-proposed changes to the conclusions of the model safety evaluation published April 4, 2003, as modified by Revision 9 of TSTF-359. This review included the NRC staffs evaluation, as well as the information provided to support TSTF-359, Revision 9. The review concluded that the justifications presented in the TSTF and in the safety evaluation prepared by the NRC staff, as modified by Revision 9 of TSTF-359, are applicable to the PNPP-proposed changes (including the change to Section 1.4 to provide consistency with SR 3.0.4) and justify this amendment to the PNPP Technical Specifications.
REGULATORY ANALYSISICOMMITMENTS Plant-specific Verification of Conformance/Applicabilitv to PNPP As discussed in the notice of availability published Inthe Federal Register on April 4, 2003, for this TS improvement, plant-specific verifications were performed as follows:
- The existing PNPP TS Bases for SR 3.0.4 already state that use of the TS mode change limitation flexibility established by LCO 3.0.4 and SR 3.0.4 "should not 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 Applicability" (a copy of the existing Bases is included in Attachment 4). This concept is maintained in the attached Bases markups. The existing TS Bases for LCO 3.0.4 contain a very similar statement; the attached markups revise the LCO 3.0.4 Bases to include the wording provided in TSTF-359.
- The modification to the PNPP Bases will also include changes to the LCO 3.0.4 and SR 3.0.4 Bases to provide details on how to Implement the new requirements (see the markups In Attachment 4). 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 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
Attachment 2 PY-CEI/NRR-2772L Page 4 of 4
- 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 in the Specification, which Is typically applied to Specifications which describe values and parameters. Although LCO 3.0.4.c may be applied to other Specifications based on NRC plant-specific approval, this submittal applies LCO 3.0.4.c only to TS 3.4.8 "Reactor Coolant System (RCS) Specific Activity"), consistent with the TSTF markups.
The Bases also state that the 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. In addition, the Bases state that 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 or until the LCO is met or the unit is not within the Applicability of the TS.
The Bases also state that SR 3.0.4 does not restrict changing MODES or other specified conditions in 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.
- Appropriate changes to the TS Bases (markups are included in Attachment 4) will be implemented concurrent with this license amendment.
- Finally, the PNPP Technical Specifications have a Bases Control Program consistent with Section 5.5 of the Standard Technical Specifications (STS), and the equivalent of STS SR 3.0.1 and its associated bases. A copy of PNPP Specifications 5.5.11 and SR 3.0.1 are included for information as part of Attachment 3, and the SR 3.0.1 Bases are included for Information in Attachment 4.
ENVIRONMENTAL CONSIDERATION An Environmental Consideration was included as Section 5.0 of the Model Safety Evaluation in the Federal Registerdated April 4, 2003. The minor modifications to TSTF-359 and the Model Safety Evaluation as discussed in the NRC-approved Revision 9 of the TSTF do not affect the April 4, 2003 Environmental Consideration. A review of the Environmental Consideration concluded that the staff's findings are applicable to PNPP, and the evaluation is hereby incorporated by reference for this application.
SIGNIFICANT HAZARDS CONSIDERATION A Proposed No Significant Hazards Consideration Determination was published in the Federal Register on April 4, 2003. The minor modifications to TSTF-359 and the Model Safety Evaluation as discussed in the NRC-approved Revision 9 of the TSTF do not affect the April 4, 2003 No Significant Hazards Consideration Determination. A review of the Proposed No Significant Hazards Consideration Determination has concluded that it is applicable to PNPP, and it is hereby incorporated by reference for this application to satisfy the requirements of 10 CFR 50.91 (a).
Attachment 3 PY-CEI/NRR-2772L Frequency Page 1f19 1.4 1.4 Frequency EXAMPLES EXAMPLE 1.4-1 (continued)
If the interval as specified by SR 3.0.2 is exceeded while the unit is not in a MODE or other specified condition in the Applicability of the LCO for which performance of the SR is required, the Surveillance must be performed within the Frequency requirements of SR 3.0.2 prior to entry into the MODE or other specified condito1) . ailure to do so would result in a violation of SR 3.0.4.

The interval measurement for the Frequency of this Surveillance continues at all times, as described in Example 1.4-1. However, the Note constitutes an "otherwise stated" exception to the Applicability of this Surveillance.
Therefore, if the Surveillance were not performed within the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> (plus the extension allowed by SR 3.0.2) interval, but the unit was not in MODE 1, there would be no failure of the SR nor failure to meet the LCO.

Attachment 4 PY-CEI/NRR-2772L Page 2 of 19 INSERT 2 FOR LCO 3.0.4 BASES (ON PAGE B 3.0-5)
CO 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.
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 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 11 ofNUMARC 93-01, "Industry Guideline for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants." These documents address general guidance for 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.
Consideration should 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.
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 3.0.4b risk assessments do not have to be documented.
The Technical Specifications allow continued operation with equipment unavailable in MODE I 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 contain Notes prohibiting 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 in the Specification which 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 justify 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 Specifications which describe values and parameters (e.g., RCS Specific Activity), and may be applied to other Specifications based on NRC plant-specific approval

SR 3.0.1 SR 3.0.1 establishes the requirement that SRs must be met during the MODES or other specified conditions in the Applicability for which the requirements of the LCO apply.
unless otherwise specified in the individual SRs. This Specification is to ensure that Surveillances are performed to verify the OPERABILITY of systems and components, and that variables are within specified limits. Failure to meet a Surveillance within the specified Frequency. in accordance with SR 3.0.2. constitutes a failure to meet an LCO.
Systems and components are assumed to be OPERABLE when the associated SRs have been met. Nothing in this Specification, however, is to be construed as implying that systems or components are OPERABLE when:
- a. The systems or components are known to be inoperable.
although still meeting-the SRs: or
- b. The requirements of the Surveillance(s) are known to be not met between required Surveillance performances.
Surveillances do not -have to be performed when the unit is in a MODE or other specified condition for which the requirements of the associated LCO are not applicable.
unless otherwise specified. The SRs associated with a Special Operations LCO are only applicable when the Special Operations LCO is used as an allowable exception to the requirements of a Specification.
- Surveillances, including 'SurveillancesT invoked by Required Actions. do not have to be performed 'n inoperable equipment because the ACTIONS define the remedial measures that apply.
Surveillances have to be met and performed in accordance with SR 3.0.2. prior to returning equipment to OPERABLE status.

SR Applicability Attachment 4 B 3.0 PY-CEI/NRR-2772L Page 5 of 19 BASES SR 3 .0 Upon completion of maintenance. appropriate post maintenance continued) testing is required to declare equipment OPERABLE. This includes ensuring applicable Surveillances are not failed and their most recent performance is in accordance with SR 3.0.2. Post maintenance testing may not be possible in the current MODE or other specified conditions in the Applicability due to the necessary unit parameters not GO Z.aR A having been established. In these situations. the equipment rr may be considered OPERABLE provided testing has been satisfactorily completed to the extent possible and the equipment is not otherwise believed to be incapable of
'T Sor~iofi performing its function. This will allow operation to proceed to a MODE or other specified condition where other necessary post maintenance tests can be completed. Some examples of this process are:
- a. Control rod drive maintenance during refueling that requires scram testing at 2 950 psig. However, if other appropriate testing is satisfactorily completed and the scram time testing of SR 3.1.4.3 is satisfied.
the control rod can be considered OPERABLE. This allows startup to proceed to reach 950 psig to perform other necessary testing.
- b. Reactor core isolation cooling (RCIC) maintenance during shutdown that requires system functional tests at a specified pressure. Provided other appropriate testing is satisfactorily completed. startup can proceed with RCIC considered OPERABLE. This allows
-operation-to-reach the specified pressure to complete the necessary post maintenance testing.
SR 3.0.2 SR 3.0.2 establishes the requirements for meeting the specified Frequency for Surveillances and any Requi red Action with a Completion Time that requires the periodic performance of the Required Action on a "once per..."
interval.
SR 3.0.2 permits a 25X extension of the interval specified in the Frequency. This extension facilitates Surveillance scheduling and considers plant operating conditions that may not be suitable for conducting the Surveillance (e.g..
transient conditions or other ongoing Surveillance or maintenance activities).

-Containment air temperature is a Category I variable provided to detect breach of the RCPB and to verify ECCS functions that operate to maintain RCS integrity. Eight wide range primary containment air temperature signals (four per channel) are transmitted from separate temperature elements and are continuously recorded and displayed on two control room recorders. However, two primary containment air temperature signals provide sufficient information to erform the above functions. and therefore only two in each Function are required to be OPERABLE. The recorders are the primary indication used by the operator during an accident.
Therefore, the PAM Specification deals specifically with this portion of the instrument channel.
APPLICABILITY The PAM instrumentation LCO is applicable in MODES 1 and 2.
These variables are related to the diagnosis and preplanned actions required to mitigate DBAs. The applicable DBAs are assumed to occur in MODES 1 and 2. In MODES 3. 4. and 5.
plant conditions are such that the likelihood of an event -
that would require PAM instrumentation is extremely low:
therefore. PAM instrumentation is not required to be OPERABLE in these MODES.

In this Condition, the remaining OPERABLE subsystems provide adequate core cooling to an inoperable HPCS during a LOCA. However. overall ECCS reliability is reduced subsystem. There is an because a single failure in one of the remaining OPERABLE increased risk associated subsystems concurrent with a LOCA may result in the ECCS not I with entering a MODE or other specified condition in 7 being able to perform its intended safety function. The day Completion Time is based on a reliability study (Ref. 12) that evaluated the impact on ECCS availability by the Applicability with an assuming that various components and subsystems were taken inoperable HPCS subsystem out of service. The results were used to calculate the and the provisions of LCO average availability of ECCS equipment needed to mitigate 3.0.4.b, which allow entry the consequences of a LOCA as a function of allowed outage into a MODE or other times (i.e..

(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 hammer effects. the RCIC System discharge line '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 RCIC 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 Statement.
LCO The OPERABILITY of the RCIC System provides adequate core cooling such that actuation of any of the ECCS.-subsystems is not required in the event of RPV isolation accompanied by a loss of feedwater flow. The RCIC System has:!su ffiient capacity to maintain RPV inventory during an fsotationh event.
APPLICABILITY The RCIC System is required to be OPERABLE in MODE 1. and MODES 2 and 3 with reactor steam dome pressure > 150 psig since RCIC is the primary non-ECCS water source for core cooling when the reactor is isolated and pressurized. In MODES 2 and 3 with reactor steam dome pressure s 150 psig.

In MODE 3. both the hydrogen production rate and the total hydrogen production after a LOCA would be less than that calculated for the DBA LOCA. Also, because of the limited time in this MODE. the probability of an accident requiring the primary containment hydrogen recombiners is low.
Therefore. the primary containment hydrogen recombiners are not required inMODE 3.
In MODES 4 and 5, the probability and consequences of a LOCA are low due to the pressure and temperature limitations in these MODES. Therefore, the primary containment hydrogen recombiners are not required in these MODES.
ACTIONS LA With one primary containment hydrogen recombiner inoperable, the inoperable primary containment hydrogen recombiner must be restored to OPERABLE status within 30 days. In this Condition, the remaining OPERABLE primary containment hydrogen recombiner is adequate to perform the hydrogen control function. However. the overall reliability is reduced because a single failure in the OPERABLE recombiner could result in reduced hydrogen control capability. The 30 day Completion Time is based on the low probability of the occurrence of a LOCA that would generate hydrogen in amounts capable of exceeding the flammability limit. the amount of time available after the event for operator action to prevent hydrogen accumulation exceeding this limit, and the low probability of failure of the OPERABLE primary containment ombiner.

LCO Proper sequencing of loads. including tripping of (continued) nonessential loads, is a required function for both offsite circuit and DG OPERABILITY for Divisions 1 and 2.
The AC sources in one division must be se parate and independent (to the extent possible) of the AC sources in the other division(s). For the DGs. the separation and independence are complete. For the offsite AC sources, the separation and independence are to the extent practical.
APPLICABILITY The AC sources are required to be OPERABLE in MODES 1. 2.
and 3 to ensure that:
A Note prohibits the a. Acceptable fuel design limits and reactor coolant application of LCO 3.0.4.b to pressure boundary limits are not exceeded as a result an inoperable DG. There is of AOOs or abnormal transients: and an increased risk associated with entering a MODE or b. Adequate core cooling is provided and containment other specified condition in OPERABILITY and other vital functions are maintained the Applicability with an in the event of a postulated DBA.
inoperable DG and the A Note has been added taking exception to the Applicability provisions of LCO 3.O.4.b, requirements for Division 3 AC sources, provided the HPCS which allow entry into a System is declared inoperable. This exception is intended MODE or other specified to allow declaring of the HPCS System inoperable either in condition in the Applicability lieu of declaring the Division 3 AC source inoperable, or at with the LCO not met after any time subsequent to entering-ACTIONS for~an inoperable performance of a risk Division 3 AC source. This exception is acceptable since.
ILassessment addressing with the HPCS System inoperable and the associated ACTIONS entered. the Division 3 AC sources provide no additional inoperable systems and assurance of meeting the above criteria.

_ LCO 3.8.2. 'AC Sources-Shutdown."
ACTIONS LIl 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 is inoperable. and Condition C. for two offs-ite circuits inoperable, is entered.
