L-2014-160 Attachment I Page 1 of 5 ATTACHMENT 1 - DESCRIPTION AND ASSESSMENT
1.0 DESCRIPTION
The proposed change provides a short Allowed Outage Time to restore an inoperable system for conditions under which the existing Technical Specifications require a plant shutdown.
The proposed amendment is consistent with TSTF-426, Revision 5, "Revise or Add Actions to Preclude Entry into LCO 3.0.3 - RITSTF Initiatives 6b & 6c."
2.0 ASSESSMENT 2.1 Applicability of Published Safety Evaluation Florida Power & Light (FPL) has reviewed TSTF-426, Revision 5, and the model safety evaluation dated May 30, 2013 as part of the Federal Register Notice of Availability. This review included a review of the Nuclear Regulatory Conmmission (NRC) staff evaluation, as well as the information provided in TSTF-426, Revision 5, and the referenced Topical Report WCAP-16 125-NP-A, Revision 2, "Justification for Risk-Informed Modifications to Selected Technical Specifications for Conditions Leading to Exigent Plant Shutdown." As described in the subsequent paragraphs, FPL has concluded that the justifications presented in the TSTF-426 proposal and the model safety evaluation prepared by the NRC staff are applicable to St.
Lucie Units 1 and 2 and justify these amendments for the incorporation of the changes to the St. Lucie Technical Specifications (TS).
2.2 Optional Changes and Variations FPL is not proposing any deviations from the Technical Specifications changes described in TSTF-426, Revision 5, or the applicable parts of the NRC staff's model safety evaluation dated May 30, 2013; however, FPL is proposing the following differences that are administrative in nature and do not affect the applicability of TSTF-426, Revision 5 to St.
Lucie Unit I and Unit 2.
- 1. St. Lucie uses different numbering and titles than in the Improved Standard Technical Specifications (ISTS) in several instances. The table below provides a cross-reference of those TS that are applicable for this application.
St. Lucie Unit 1 St. Lucie Unit 2 ISTS N/A TS 3.4.3, "Pressurizer" TS 3.4.9, "Pressurizer" TS 3.6.2, "Containment TS 3.6.2, "Containment TS 3.6.6A, "Containment Spray and Cooling Spray and Cooling Spray and Cooling Systems" Systems" Systems" TS 3.6.6.1, "Shield TS 3.6.6.1, "Shield TS 3.6.8, "Shield Building Building Ventilation Building Ventilation Exhaust Air Cleanup System (SBVS)" System (SBVS)" System (SBEACS)"
TS 3.7.7, "Control Room TS 3.7.7, "Control Room TS 3.7.11, "Control Room Emergency Ventilation Emergency Air Cleanup Emergency Air Cleanup System" System (CREACS)" System (CREACS)"
L-2014-160 Attachment I Page 2 of 5 St. Lucie Unit 1 St. Lucie Unit 2 ISTS TS 3.7.7, "Control Room TS 3.7.7, Control Room TS 3.7.12, "Control Room Emergency Ventilation Emergency Air Cleanup Emergency Air System" System (CREACS)" Temperature Control System (CREATCS)"
- 2. The Unit 1 and Unit 2 designs do not include an independent Iodine Cleanup System (ICS). Each unit's Containment Spray System in conjunction with the Spray Additive System (Unit 1) and Iodine Removal System (Unit 2) is credited for iodine removal.
Additionally, neither unit has a separate Penetration Room Exhaust Air Cleanup System. Therefore, the TSTF-426, Revision 5 changes for ICS are not included. This variation is administrative and does not affect the applicability of TSTF-426, Revision 5 to St. Lucie Unit 1 and Unit 2.
- 3. The Unit I Control Room Emergency Ventilation System (CREVS) and Unit 2 Control Room Emergency Air Cleanup System (CREACS) maintain habitability and provide cooling in the control room; therefore, each is equivalent in function to the Control Room Emergency Air Cleanup System (CREACS) and, for cooling only, the Control Room Air Temperature Control System (CREATCS). The CREVS differs in design being that the CREVS is not physically a two independent train system. A common filter train is shared by what are otherwise two physically and electrically independent CREVS "trains." Furthermore, the CREVS has three air conditioning units as opposed to two. At present, the Unit 1 TS do not address a loss of CREVS function -- for habitability or cooling -- caused by inoperability of both booster fans (effectively one per "train") or inoperability of all air conditioning units, respectively. As a result, an Action for inoperability of both booster fans with a 24-hour restoration period and other elements required by TSTF-426, Revision 5 is included for the CREVS habitability function in Modes 1, 2, 3, and 4. In addition, the current Action for inoperability of the common filter train in Modes 1, 2, 3, and 4, which also constitutes a loss of the CREVS habitability function, has been modified accordingly. Lastly, an Action has been included to address inoperability of all air conditioning units for loss of the CREVS cooling function, again, with a 24-hour restoration period. These variations meet the intent of the TSTF-426, Revision 5 changes for the CREACS and CREATCS.
Consequently, these variations are administrative and do not affect the applicability of TSTF-426, Revision 5 to St. Lucie Unit 1. There are no similar variations from TSTF-426, Revision 5 required for St. Lucie Unit 2.
- 4. Changes to Pressurizer Heaters (for Unit I only), Pressurizer Power Operated Relief Valves (PORVs), and the Control Room Emergency Air Temperature Control System were not included in the WCAP-16125-NP-A, Revision 2 evaluation. Therefore, the TSTF-426, Revision 5 changes for the equivalent systems are not included in this request. These variations are administrative and do not affect the applicability of TSTF-426, Revision 5 to St. Lucie Unit 1 and Unit 2.
- 5. The change to the Emergency Core Cooling System (ECCS) Pump Room Exhaust Air Cleanup System (ISTS) is not included. This change is prohibited in that the equivalent
L-2014-160 Attachment I Page 3 of 5 system for Unit 1 and Unit 2, ECCS Area Ventilation System, performs a temperature control function which may impact the operability of the ECCS pumps and equipment.
- 6. Unit 1 and Unit 2 TS address PORV Block Valves only. TS 3.4.12, "PORV Block Valves," and TS 3.4.4, "PORV Block Valves," respectively, currently contain an Action for one or more PORV block valves inoperable. Within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> it is required to either restore the block valve(s) to OPERABLE status, or close the block valve(s) and remove power from the block valve(s). Although a change to the equivalent TS was approved in TSTF-426, Revision 5, FPL is not pursuing the change. Since each TS change was evaluated separately in WCAP-16125-NP-A, Revision 2, failure to adopt this change will not have an impact on the acceptability of adopting the remaining changes which apply. This variation is administrative and does not affect the applicability of TSTF-426, Revision 5, to the St. Lucie TS.
- 7. St. Lucie Unit 1 and Unit 2 TS contain requirements for the Boration System which do not appear in the Inproved Standard Technical Specifications and, therefore, do not appear in TSTF-426. The referenced Topical Report, WCAP-16125-NP-A, included changes to the Boration System TS that were found to be acceptable by the NRC. As a result, proposed changes are included to the St. Lucie Unit I and Unit 2 Boration System TS, consistent with those evaluated and found acceptable in WCAP-16 125-NP-A.
2.3 Licensee Verifications St. Lucie confirms no licensee verifications are required.
3.0 REGULATORY ANALYSIS
3.1 No Significant Hazards Consideration Determination FPL requests adoption of TSTF-426, Revision 5, "Revise or Add Actions to Preclude Entry into LCO 3.0.3 - RITSTF Initiatives 6b & 6c," which is an approved change to the standard technical specifications (STS), into the St. Lucie Unit I and Unit 2 Technical Specifications.
The proposed change provides a short Allowed Outage Time to restore an inoperable system for conditions under which the existing Technical Specifications require a plant shutdown to begin within one hour in accordance with Limiting Condition for Operation (LCO) 3.0.3.
FPL has evaluated whether or not a significant hazards consideration is involved with the proposed amendments by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of Amendment," as discussed 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 provides a short Allowed Outage Time to restore an inoperable system for conditions under which the existing Technical Specifications require a plant
L-2014-160 Attachment 1 Page 4 of 5 shutdown to begin within one hour in accordance with Limiting Condition for Operation (LCO) 3.0.3. Entering into Technical Specification Actions is not an initiator of any accident previously evaluated. As a result, the probability of an accident previously evaluated is not significantly increased. The consequences of any accident previously evaluated that may occur during the proposed Allowed Outage Times are no different from the consequences of the same accident during the existing one-hour allowance. As a result, the consequences of any accident previously evaluated are not significantly increased.
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.
No new or different accidents result from utilizing the proposed change. The changes do not involve a physical alteration of the plant (i.e., no new or different type of equipment will be installed) or a change in the methods governing normal plant operation. In addition, the changes do not impose any new or different requirements. The changes do not alter assumptions made in the safety analysis.
Therefore, the proposed change does not create the possibility of a new or different kind of accident from any previously evaluated.
- 3. Does the proposed change involve a significant reduction in a margin of safety?
Response: No.
The proposed change increases the time the plant may operate without the ability to perform an assumed safety function. The analyses in WCAP-16125-NP-A, "Justification for Risk-Informed Modifications to Selected Technical Specifications for Conditions Leading to Exigent Plant Shutdown," Revision 2, August 2010, demonstrated that there is an acceptably small increase in risk due to a limited period of continued operation in these conditions and that this risk is balanced by avoiding the risks associated with a plant shutdown. As a result, the change to the margin of safety provided by requiring a plant shutdown within one hour is not significant.
Therefore, the proposed change does not involve a significant reduction in a margin of safety.
Based on the above, FPL concludes that the proposed change presents no significant hazards consideration under the standards set forth in 10 CFR 50.92(c), and, accordingly, a finding of "no significant hazards consideration" is justified.
L-2014-160 Attachment 1 Page 5 of 5 4.0 ENVIRONMENTAL EVALUATION The proposed change would change a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR 20, or 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 occupational radiation exposure. Accordingly, the proposed change meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(9). Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed change.

BASES (continued) 314.1.2 BORATION SYSTEMS The boron injection system ensures that negative reactivity control is available during each mode of facility operation. The components required to perfomi this function include 1) borated water sources,
- 2) charging pumps, 3) separate flow paths, 4) boric acid pumps, and
- 5) an emergency power supply from OPERABLE diesel generators.
With the RCS average temperature above 200 0 F, a minimum of two separate and redundant boron injection systems are provided to ensure single functional capability in the event an assumed failure renders one of the systems inoperable. Allowable out-of-service periods ensure that minor component repair or corrective action may be completed without undue risk to overall facility safety from injection system failures during the repair period.
The boration capability of either system is sufficient to provide a SHUTDOWN MARGIN from all operating conditions corresponding to the requirements of Specification 3.1.1.2 after xenon decay and cooldown to 200 0 F. The maximum boration capability requirement occurs at EOL from full power equilibrium xenon conditions. This requirement can be met for a range of boric acid concentrations in the Boric Acid Makeup Tanks (BAMTs) and Refueling Water Tank (RWT). This range is bounded by 6800 gallons of 3.5 weight percent (6119 ppm boron) boric acid from the BAMTs and 17,000 gallons of '1900 ppm borated water from the RWT to 8700 gallons of 3.0 weight percent (5245 ppm boron) boric acid from the BAMTs and 13,000 gallons of 1900 ppm borated water from the RWT.
A minimum of 45,000 gallons of 1900 ppm boron is required from the RWT if it is to be used to borate the RCS alone.
The requirements for a minimum contained volume of 401,800 gallons of borated water in the refueling water tank ensures the capability for borating the RCS to the desired level. The specified quantity of borated water is consistent with the ECCS requirements of Specification 3.5.4.
Therefore, the larger volume of borated water is specified here as well.
IINSERT lB-,
With the RCS temperature below 200 0 F, one injection system is acceptable without single failure consideration on the basis of the stable reactivity condition of the reactor and the additional restrictions prohibiting CORE ALTERATIONS and positive reactivity change in the event the single injection system becomes inoperable.

BASES (continued) 3/4.1.2 BORATION SYSTEMS (continued)
Temperature changes in the RCS impose reactivity changes by means of the moderator temperature coefficient. Plant temperature changes are allowed provided the temperature change is accounted for in the calculated SDM. Small changes in RCS temperature are unavoidable and so long as the required SDM is maintained during these changes, any positive reactivity additions will be limited to acceptable levels.
Introduction of temperature changes must be evaluated to ensure they do not result in a loss of required SDM.
The boron addition capability after the plant has been placed in MODES 5 and 6 requires either 3650 gallons of 3.0 to 3.5 weight percent boric acid solution (5245 to 6119 ppm boron) from the boric acid tanks or 11,900 gallons of 1900 ppm borated water from the refueling water tank to makeup for contraction of the primary coolant that could occur if the temperature is lowered from 200OF to 140 0 F.
The restrictions associated with the establishing of the flow path from the RWT to the RCS via a single HPSI pump provide assurance that 10 CFR 50 Appendix G pressure/temperature limits will not be exceeded in the case of any inadvertent pressure transient due to a mass addition to the RCS. If RCS pressure boundary integrity does not exist as defined in Specification 1-16, these restrictions are not required. Additionally, a limit on the maximum number of operable HPSI pumps is not necessary when the pressurizer manway cover or the reactor vessel head is removed.
Ensuring that the BAM pump discharge pressure is met satisfies the periodic surveillance requirement to detect gross degradation caused by impeller structural damage or other hydraulic component problems. Along with this requirement, Section Xl of the ASME Code verifies the pump developed head at one point on the pump characteristic curve to verify both that the measured performance is within an acceptable tolerance of the original pump baseline perfomiance and that the performance at the test flow is greater than or equal to the performance assumed in the unit safety analysis. Surveillance Requirements are specified in the Inservice Testing Program, which encompasses Section Xl of the ASME Code.
Section Xl of the ASME Code provides the actMties and frequencies necessary to satisfy the requirements.

In order for the CREVS to be considered OPERABLE, the CRE boundary must be maintained such that the CRE occupant dose from a large radioactive release does not exceed the calculated dose in the licensing basis consequence analyses for DBAs, and that CRE occupants are protected from smoke.
The LCO is modified by a Note allowing the CRE boundary to be opened intermittently under administrative controls. This Note only applies to openings in the CRE boundary that can be rapidly restored to the design condition, such as doors, hatches, floor plugs, and access panels. For entry and exit through doors, the administrative control of the opening is performed by the person(s) entering or exiting the area. For other openings, these controls should be proceduralized and consist of stationing a dedicated individual at the opening who is in continuous communication with the operators in the CRE. This individual will have a method to rapidly close the opening and to restore the CRE boundary to a condition equivalent to the design condition when a need for CRE isolation is indicated.
In MODES 1, 2, 3, or 4, the CREVS must be OPERABLE to ensure that the CRE will remain habitable to limit operator exposure during and following a DBA. T--INRT7B If the unfiltered inleakage of potentially contaminated air past the CRE boundary and into the CRE can result in CRE occupant radiological dose greater than the calculated dose of the licensing basis analyses of DBA consequences (allowed to be up to 5 rem total effective dose equivalent -

Insert 7B If the CREVS function, whether that for maintaining control room habitability or for cooling, is lost in MODE 1, 2, 3, or 4 due to the filter train, both booster fans, or all (three) air conditioning units being inoperable for reasons other than an inoperable CRE boundary, the filter train, at least one booster fan, or at least one air conditioning unit must be returned to OPERABLE status within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> (Action c, Action e, and Action f), respectively.

Action e and Action f do not apply to voluntary removal of redundant systems or components from service. Action e is only applicable if one booster fan is inoperable for any reason and the second booster fan is discovered to be inoperable, or if both booster fans are discovered to be inoperable at the same time. Action f is only applicable if one or two air conditioning units are inoperable for any reason and the remaining two or the remaining one air conditioning unit(s),
respectively, is discovered to be inoperable, or if all air conditioning units are discovered to be inoperable at the same time. During the period that components are inoperable such that the CREVS function for maintaining habitability is lost, action must be initiated to implement mitigating actions to lessen the effect on CRE occupants from potential hazards. In the event of a DBA, the mitigating actions will reduce the consequences of radiological exposures to the CRE occupants. Specification 3.4.8, "Specific Activity," allows limited operation with the reactor coolant system (RCS) activity significantly greater than the LCO limit. This presents a risk to the plant operator during an accident when the CREVS control room habitability function is lost.

BASES (continued) 314.1.2 BORATION SYSTEMS The boron injection system ensures that negative reactivity control is available during each mode of facility operation. The components required to perform this function indude (1) borated water sources, (2) charging pumps, (3) separate flow paths, (4) boric acid makeup pumps, and (5) an emergency power supply from OPERABLE diesel generators.
With the RCS average temperature above 200 0 F, a minimum of two separate and redundant boron injection systems are provided to ensure single functional capability in the event an assumed failure renders one of the systems inoperable. Allowable out-of-service periods ensure that minor component repair or corrective action may be completed without undue risk to overall facility safety from injection system failures during the repair period.
The boration capability of either system is sufficient to provide a SHUTDOWN MARGIN from expected operating conditions of the limit specified in the COLR after xenon decay and cooldown to 200 0 F. The maximum expected boration capability requirement occurs at EOL from full power equilibrium xenon conditions. This requirement can be met for a range of boric acid concentrations in the Boric Acid Makeup Tank (BAMT) and Refueling Water Tank (RWT). This range is bounded by 8,750 gallons of 3.1 weight percent (5420 ppm boron) from the BAMT and 10,492 gallons of 1900 ppm borated water from the RWT to 7,550 gallons of 3.5 weight percent (6119 ppm boron) boric acid from BAMT and 11,692 gallons of 1900 ppm borated water from the RWT. A minimum of 33,000 gallons of 1900 ppm boron is required from the RWT if it is to be used to borate the RCS alone. This volume requirement, however, is expected to always be bounded by the ECCS RWT JINSERT IBi volume requirements of Specification 3.5.4.
With the RCS temperature below 200°F one injection system is acceptable without single failure consideration on the basis of the stable reactivity condition of the reactor and the additional restrictions prohibiting CORE ALTERATIONS and positive reactivity changes in the event the single injection system becomes inoperable.

Temperature changes in the RCS impose reactivity changes by means of the moderator temperature coefficient. Plant temperature changes are allowed provided the temperature change is accounted for in the calculated SDM.
Small changes in RCS temperature are unavoidable and so long as the required SDM is maintained during these changes, any positive reactivity additions will be limited to acceptable levels. Introduction of temperature changes must be evaluated to ensure they do not result in a loss of required SDM_
The boron capability required below 200°F is based upon providing a SHUTDOWN MARGIN corresponding to its COLR limit after xenon decay and cooldown from 200°F to 140 0F. This condition can be satisfied by maintaining either 1443 gallons of 1900 ppm borated water from the refueling water tank or 1433 gallons of 3.1 weight percent boric acid solution from the boric acid makeup tanks.
The contained water volume limits includes allowance for water not available because of discharge line location and other physical characteristics.
The OPERABILITY of one boron injection system during REFUELING ensures that this system is available for reactivity control while in MODE 6.
The limits on contained water volume and boron concentration of the RWT also ensure a pH value of between 7.0 and 8.1 for the solution recirculated within containment after a LOCA. This pH band minimizes the evolution of iodine and minimizes the effect of chloride and caustic stress corrosion on mechanical systems and components.
Ensuring that the BAM pump discharge pressure is met satisfies the periodic surveillance requirement to detect gross degradation caused by impeller structural damage or other hydraulic component problems. Along with this requirement, Section Xl of the ASME Code verifies the pump developed head at one point on the pump characteristic curve to verify both that the measured performance is within an acceptable tolerance of the original pump baseline performance and that the performance at the test flow is greater than or equal to the performance assumed in the unit safety analysis.

Pressurizer code safety valves are to be tested in accordance with the requirements of Section XI of the ASME Code, which provides the activities and the frequency necessary to satisfy the Surveillance Requirements. No additional requirements are specified.
The pressurizer code safety valve as-found setpoint is 2500 psia +1- 3% for OPERABILITY; however, the valves are reset to 2500 psia +/- 1% during the Surveillance to allow for drift. The LCO is expressed in units of psig for consistency with implementing procedures.
3/4.4.3 PRESSURIZER A OPERABLE pressurizer provides pressure control for the Reactor Coolant System during operations with both forced reactor coolant flow and with natural circulation flow. The minimum water level in the pressurizer assures the pressurizer heaters, which are required to achieve and maintain pressure control, remain covered with water to prevent failure, which could occur if the heaters were energized uncovered. The maximum water level in the pressurizer ensures that this parameter is maintained within the envelope of operation assumed in the safety analysis. The maximum water level also ensures that the RCS is not a hydraulically solid system and that a steam bubble will be provided to accommodate pressure surges during operation.
The steam bubble also protects the pressurizer code safety valves against water relief. The requirement to verify that on an Engineered Safety Features Actuation test signal concurrent with a loss of offsite power the pressurizer heaters are automatically shed from the emergency power sources is to ensure that the non-Class 1 E heaters do not reduce the reliability of or overioad the emergency power source. The requirement that a minimum number of pressurizer heaters be OPERABLE enhances the capability to control Reactor Coolant System pressure and establish and maintain natural circulation.

This requirement is necessary to meet the assumptions used in the safety analyses and limit the site boundary radiation doses to within the limits of 10 CFR 50.67 during LOCA conditions.
The fuel handling accident analysis assumes a minimum post reactor shutdown decay time of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. Therefore, recently irradiated fuel is defined as fuel that has occupied part of a critical reactor core within the previous 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. This represents the applicability bases for fuel handling accidents.
Containment closure will have administrative controls in place to assure that a single normal or contingency method to promptly close the primary or secondary containment penetrations will be available. These prompt methods need not completely block the penetrations nor be capable of resisting pressure, but are to enable the ventilation systems to draw the release from the postulated fuel handling accident in the proper direction such that it can be treated and monitored.
Operation of the system with the heaters on for at least 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> continuous over a 31-day period is sufficient to reduce the buildup of moisture on the adsorbers and HEPA filters.

3/4.6.6.2 SHIELD BUILDING INTEGRITY SHIELD BUILDING INTEGRITY ensures that the release of radioactive materials from the primary containment atmosphere will be restricted to those leakage paths and associated leak rates assumed in the safety analyses. This restriction, in conjunction with operation of the shield building ventilation system, will ensure that the site boundary radiation doses are below the guidelines established for design basis.
3/4.6.6.3 SHIELD BUILDING STRUCTURAL INTEGRITY This limitation ensures that the structural integrivy of the containment shield building will be maintained comparable to the original design standards for the life of the facility. Structural integrity is required to provide (1) protection for the steel vessel from the external missiles, (2) radiation shielding in the event of a LOCA, and (3) an annulus surrounding the steel vessel that can be maintained at a negative pressure during accident conditions. A visual inspection is sufficient to demonstrate this capability.

During the period that the CRE boundary is considered inoperable, action must be initiated to implement mitigating actions to lessen the effect on CRE occupants from the potential hazards of a radiological event or a challenge from smoke. Actions must be taken within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to verify that in the event of a DBA, the mitigating actions will ensure that CRE occupant radiological exposures will not exceed the calculated dose of the licensing basis analyses of DBA consequences, and that CRE occupants are protected from smoke.
These mitigating actions (i-e., actions that are taken to offset the consequences of the inoperable CRE boundary) should be preplanned for implementation upon entry into the condition, regardless of whether entry is intentional or unintentional. The 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> allowable outage time (AOT) is reasonable based on the low probability of a DBA occurring during this time period, and the use of mitigating actions. The 90 day AOT is reasonable based on the determination that the mitigating actions will ensure protection of CRE occupants within analyzed limits while limiting the probability that CRE occupants will have to implement protective measures that may adversely affect their ability to control the reactor and maintain it in a safe shutdown condition in the event of a DBA. In addition, the 90 day AOT is a reasonable time to diagnose, plan and possibly repair, and test most problems with the CRE boundary.
In MODE 1, 2, 3, or 4, ifthe inoperable CREACS or the CRE boundary cannot be restored to OPERABLE status within the required AOT, the unit must be placed in a MODE that minimizes the accident risk. To achieve this status, the unit must be placed in at least MODE 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, and in MODE 5 within 3630 hours0.042 days <br />1.008 hours <br />0.006 weeks <br />0.00138 months <br />. The AOT are reasonable, based on operating experience, to reach the required unit conditions from full power conditions in INSERT 8B an ordery manner and without challenging unit systems.
When in MODES 5 and or 6, or during movement of irradiated fuel assemblies, with both CREACS trains inoperable or with one or more CREACS trains inoperable due to an inoperable CRE boundary, action must be taken immediately to suspend activities that could result in a release of radioactivity that might require isolation of the CRE. This places the unit in a condition that minimizes the accident risk. This does not predude the movement of fuel to a safe position.

The Surveillance Requirement (SR) 4.7.7.e verifies the OPERABILITY of the CRE boundary by testing for unfiltered air inleakage past the CRE boundary and into the CRE. The details of the testing are specified in the Control Room Envelope Habitability Program.
The CRE is considered habitable when the radiological dose to CRE occupants calculated in the licensing basis analyses of DBA consequences is no more than 5 rem TEDE and the CRE occupants are protected from hazardous chemicals and smoke. This SR verifies that the unfiltered air inleakage into the CRE is no greater than the flow rate assumed in the licensing basis analyses of DBA consequences. When unfiltered air inleakage is greater than the assumed flow rate in Modes 1, 2, 3, and 4, ACTION b must be taken. Required ACTION b.3 allows time to restore the CRE boundary to OPERABLE status provided mitigating actions can ensure that the CRE remains within the licensing basis habitability limits for the occupants following an accident. Compensatory measures are discussed in Regulatory Guide 1.196, Section C.2.7.3, which endorses, with exceptions, NEI 99-03, Section 8.4 and Appendix F. These compensatory measures may also be used as mitigating actions as required by Required Action b_2.
Temporary analytical methods may also be used as compensatory measures to restore OPERABILITY, as discussed in letter from Eric J. Leeds (NRC) to James W. Davis (NEI) dated January 30, 2004, 'NEI Draft White Paper, Use of Generic Letter 91-18 Process and Alternative Source Terms in the Context of Control Room Habitability." Options for restodng the CRE boundary to OPERABLE status indude changing the licensing basis DBA consequence analysis, repairing the CRE boundary, or a combination of these actions.
Depending upon the nature of the problem and the corrective action, a full scope inleakage test may not be necessary to establish that the CRE boundary has been restored to OPERABLE status.
