St. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 Proposed License Amendments Technical Specification Improvements Associated with Handling of Recently Irradiated Fuel Assemblies Pursuant to 10 CFR 50.90, Florida Power & Light Company (FPL) requests to amend Facility Operating Licenses DPR-67 and NPF-16 for St. Lucie Units 1 and 2.

The proposed amendments revise Unit 1 and Unit 2 Technical Specifications (TS) to incorporate line item improvements associated with the handling of recently irradiated fuel assemblies in accordance with Revision 2 of NUREG-1432, Standard Technical Specifications Combustion Engineering Plants (STS) and a portion of Nuclear Energy Institute (NEI) TS Task Force (TSTF) change traveler TSTF-51, Revision 2. The proposed changes modify Unit 1 and Unit 2 TS Sections 3.9.4 and 3.9.9, Unitl TS Section 3.9.12, and Unit 2 TS Sections 3.6.6.1.

TSTF-51, incorporated into Revision 2 of the STS, removed the TS applicability regarding operability of certain systems (containment penetrations, spent fuel pool and shield building ventilation, and containment isolation) when handling fuel assemblies that have decayed a sufficient period of time such that dose consequences for the postulated fuel handling accident (FHA) remain well below the limits given in 10 CFR 100 and within the limits given in the NRC Standard Review Plan (SRP) when these systems are not available.

Further, the FHA analyses do not credit the subject systems and rely on decay of the fission product inventory to ensure that the dose consequences remain below the SRP limits. Therefore, the TSs that pertain to these systems during fuel handling can be revised to limit their applicability to recently irradiated fuel assemblies. Recently irradiated fuel will be defined in the TS Bases 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 />.

St. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 L-2002-089 Attachment 1 Page 1 ATTACHMENT 1 SAFETY ANALYSIS Introduction Florida Power and Light Company (FPL) proposes to revise the St. Lucie Units 1 and 2 Technical Specifications (TS) to incorporate line item improvements associated with the handling of recently irradiated fuel assemblies in accordance with Revision 2 of NUREG-1432, Standard Technical Specifications Combustion Engineering Plants (STS) and TSTF-51.

The STS remove the TS applicability regarding operability of certain systems (containment penetrations, spent fuel pool and shield building ventilation, and containment isolation) when handling fuel assemblies that have decayed a sufficient period of time such that dose consequences for the postulated fuel handling accident (FHA) remain below the limits of the Standard Review Plan (SRP) when these systems are not available. The design bases FHA analyses for St. Lucie Units 1 and 2 are based on a fission product inventory that has decayed 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. Further, the FHA analyses do not credit the subject systems and rely on decay of the fission product inventory to ensure that the dose consequences remain below the SRP limits. Therefore, the TSs that pertain to these systems during fuel handling can be revised to limit their applicability to recently irradiated fuel assemblies. Recently irradiated fuel will be defined in the TS Bases 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 />. Partial implementation of STS criteria was applied to containment penetration specifications during refueling by Unit 1 and Unit 2 License Amendments 172 and 120, respectively. The proposed license amendments would incorporate the remaining applicable line item improvements and provide consistency between the two St. Lucie units.

Background

TSTF-51 Revision 2 was incorporated into Revision 2 of NUREG-1432. TSTF-51 removes the TS applicability regarding operability of certain systems (containment penetrations, spent fuel pool and shield building ventilation, and containment isolation) when handling fuel that has decayed a sufficient period of time such that dose consequences for the postulated FHA remain below the limits of the SRP when these systems are not available.

The design basis FHA analyses for St. Lucie Units 1 and 2 are based on a fission product inventory that has decayed 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> giving no credit for the subject systems. Therefore, the TSs that pertain to these systems can be revised to limit their applicability to recently irradiated fuel assemblies, where recently irradiated fuel will be defined in the TS bases 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 />.

The analyses of the dose consequences for the FHA for St. Lucie Units 1 and 2 were performed based on the methodology outlined in Regulatory Guide (RG) 1.25 (Reference 6). The FHA analyses assume that the entire fission gas inventory in the fuel rod gap for all the fuel rods in the highest power fuel assembly is released over a two-hour period.

St. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 L-2002-089 Attachment 1 Page 2 There is no credit taken for containment or the fuel handling building isolation or filtering systems. Therefore, the consequences of these analyses bound the FHAs in the fuel handling building and in the reactor containment building. In these FHA analyses, the minimum water level above the fuel is 23 feet, supporting a conservative assumption of an overall decontamination factor of 100 for the iodine isotopes released from the damaged fuel assembly. Also, the FHA analyses assume that the containment does not preclude or mitigate the dispersion of the activity release from the damaged fuel assembly.

The methodology used in calculating the control room doses is derived from an expression provided in Nuclear Power Plant Control Room Ventilating System Design for Meeting General Design Criteria (GDC) 19, 13th AEC Air Cleaning Conference, CONF740-807, Vol.

1, which determines the radiological doses based on an activity balance within the control room. The design basis Westinghouse FHA analyses, Determination of Fuel Handling Accident Radiological Releases in Support of St. Lucie TSs 3.9.4 (references 14 and 15) were submitted to the NRC in support of License Amendments 172 and 120 by FPL letters L-2000-222 dated October 30, 2000 and L-2001-083 dated June 22, 2001 for Unit 1 and Unit 2, respectively.

The results of the Unit 1 analysis are as follows:

"* Control Room Dose 8.48 rem - thyroid and 0.013 rem - whole body

"* Limiting Exclusion Area Boundary Dose (EAB) 59.1 rem - thyroid and 0.68 rem - whole body

"* Low Population Zone Dose (LPZ) 27.9 rem - thyroid and 0.319 rem - whole body The results of the Unit 2 analysis are as follows:

"* Control Room Dose 9.39 rem - thyroid and 0.02 rem - whole body

"* Limiting Exclusion Area Boundary Dose 61.6 rem - thyroid and 0.75 rem - whole body

"* Low Population Zone Dose 26.7 rem - thyroid and 0.33 rem - whole body These values remain well within the criteria specified in NUREG-0800, Standard Review Plan, Section 15.7.4, Radiological Consequences of Fuel Handling Accidents.

The NRC acceptance criteria for control room habitability as provided in Section 6.4 in NUREG-0800 is 30 rem for inhalation thyroid dose and 5 rem for the whole body gamma dose. The calculated control room doses indicate that these dose acceptance criteria are met with significant margins.

St. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 L-2002-089 Attachment 1 Page 3 Description of the Proposed Change FPL proposes to change the following TSs in support of the proposed amendments.

SURVEILLANCE REQUIREMENTS:

4.9.9 The containment isolation system shall be demonstrated OPERABLE within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> prior to the start of and at least once per 7 days during CORE A"L TERAT ON movement of recently irradiated fuel by verifying that containment isolation occurs on manual initiation and on a high radiation test signal from each of the containment radiation monitoring instrumentation channels.

Justification The proposed TS changes to the applicability, actions, and surveillance requirements of certain systems (containment penetrations, spent fuel pool and shield building ventilation, and containment isolation) are based on the FHA analyses that demonstrate that sufficient radioactive decay has occurred after 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> such that the resulting dose consequences are within SRP limits. The systems that have been included in the proposed change will have administrative controls in place to assure that the systems are available and can be promptly returned to operation to further reduce dose consequences.

These administrative controls will include a single normal or contingency method to promptly close the primary or secondary containment penetrations. 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 FHA such that it can be treated and monitored.

Evaluation Containment Integrity TS 3.6.1.1, Containment Integrity, requires that containment integrity be maintained while in MODES 1 through 4. During MODES 1 through 4, the reactor coolant system contains

St. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 L-2002-089 Attachment 1 Page 7 significant energy that provides the motive force for the expulsion of radionuclides subsequent to a design basis accident (DBA). The relaxation described in this evaluation is being sought for MODE 6 where the effect of a FHA inside containment is the event of concern and is bounded by the DBA.

Containment Closure TS 3.9.4, Containment Penetrations, requires that a minimum of one door on each containment airlock, the equipment door, as well as other containment penetrations (except as permitted under administrative controls), be closed during core alterations or movement of irradiated fuel within the containment. This requirement is more conservative than the assumptions used in the St. Lucie Unit 1 and Unit 2 FHA analyses that assumed in the event of a FHA in containment, all of the iodine and noble gases that become airborne within the containment, escape within a two-hour period and reach the site boundary and low population zone with no credit taken for the containment building barrier.

The FHA analyses also assume 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 /> prior to fuel movement to ensure that the dose consequences are within SRP limits. The proposed changes eliminate the applicability of this TS for core alterations or when irradiated fuel that has decayed a minimum of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> is being moved. Since the only accident postulated to occur during core alterations that results in significant radioactive release is the FHA, removing the requirement for applicability during core alterations is justified. The FHA analyses demonstrate that sufficient decay has occurred such that the primary path for mitigating the dose consequences of the FHA no longer includes the functions of the active containment systems. Instead, water level and decay time are the primary success paths for mitigating the dose consequences of the FHA. Nevertheless, containment closure capability 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 FHA such that it can be treated and monitored.

Containment Isolation System TS 3.9.9, Containment Isolation System, requires that the system be operable during core alterations or the movement of irradiated fuel. The proposed changes eliminate the applicability of this TS for core alterations or when irradiated fuel that has decayed a minimum of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> is being moved. Since the only accident postulated to occur during core alterations that results in significant radioactive release in the FHA, removing the requirement for applicability during core alterations is justified. As discussed above, isolation of the containment is not assumed in the FHA analyses. Instead, water level and decay time are the primary success paths for mitigating the dose consequences of the FHA. However, the FHA assumes that the control room ventilation system is operable and that outside air intake will be isolated in 30 minutes and switches to a filtered recirculation

St. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 L-2002-089 Attachment 1 Page 8 mode.

This can be accomplished either by automatic or manual initiation of the containment isolation system (CIS) or by manual isolation of the control room outside air intakes. Operator action within 30 minutes of notification of a FHA is reasonable since direct communication between the control room and refueling personnel is required during core alterations by TS 3.9.5.

Fuel Pool Ventilation System (Unit 1) and Shield Buildingq Ventilation System (Unit 2)

TS 3.9.12, Fuel Pool Ventilation System, for Unit 1 and TS 3.6.6.1, Shield Building Ventilation System, for Unit 2, require that the systems be operable when irradiated fuel is located within the fuel pool. The proposed changes eliminate the applicability of this TS when irradiated fuel that has decayed a minimum of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> is being moved or for crane operations with loads over such irradiated and decayed fuel. The FHA analyses were performed assuming no credit for fuel pool ventilation nor shield building ventilation filtering systems. Nevertheless, these systems will have administrative controls in place to assure that the systems can be returned to operation by a single normal or contingency method. These methods need not completely block the penetrations or be capable of resisting pressure, but are to enable the ventilation systems to draw the release from the postulated FHA such that it can be treated and monitored.

Applicable Regulatory Requirements/Criteria NUREG-0800, Standard Review Plan, Section 15.7.4, Radiological Consequences of Fuel Handling Accidents, describes the acceptance criteria for this event as, "the calculated doses at the exclusion boundary are well within the exposure guidelines of 10 CFR Part 100...well within shall mean 25% or less of 10 CFR Part 100, i.e., 75 Rem to the thyroid and 6 Rem for the whole-body doses." Neither the original nor the revised design basis FHA analyses take credit for the containment building barriers.

The results of the calculations performed show that the offsite dose consequences of a fuel assembly dropped inside containment are well within the 10 CFR Part 100 limits Regulatory Guide 1.25 is the NRC guidance that describes a method acceptable to the NRC staff for licensee evaluation of the potential radiological consequences of a FHA.

The parameters of concern and the acceptance criteria applied are based on the requirements of 10 CFR 100 with respect to the calculated radiological consequences of a FHA and GDC 61 with respect to appropriate containment, confinement, and filtering systems.

NUREG/CR-5009, Assessment of the Use of Extended Burnup Fuel in Light Water Power Reactors, relates to the expected release fraction for the radioactive iodine. According to this report, the calculated release fraction for extended burnup fuel may be up to 20%

higher than that assumed in Regulatory Guide 1.25 for iodine-131. See NUREG/CR-3011 and RG 1.109 (references 8 and 13) for related guidelines.

St. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 L-2002-089 Attachment 1 Page 9 The methodology, assumptions, and results of the revised FHA with the proposed TS changes demonstrate compliance with the applicable regulatory requirements, criteria, and guidance.

10 CFR Part 50, Appendix A, General Desigqn Criteria (GDC)

GDC 16, Containment Design, requires that reactor containment and associated systems shall be provided to establish an essentially leak-tight barrier against the uncontrolled release of radioactivity to the environment and to assure that the containment design conditions important to safety are not exceeded for as long as the postulated accident conditions require.

GDC 19, Control Room, requires that a control room shall be provided from which actions can be taken to operate the nuclear power unit safely under normal conditions and to maintain it in a safe condition under accident conditions, including loss-of-coolant accidents.

Adequate radiation protection shall be provided to permit access and occupancy of the control room under accident conditions without personnel receiving radiation exposures in excess of 5 rem whole body, or its equivalent to any part of the body, for the duration of the accident. Equipment at appropriate locations outside the control room shall be provided (1) with a design capability for prompt hot shutdown of the reactor, including necessary instrumentation and controls to maintain the unit in a safe condition during hot shutdown, and (2) with a potential capability for subsequent cold shutdown of the reactor through the use of suitable procedures.

GDC 54, Piping Systems Penetrating Containment, requires that piping systems penetrating primary reactor containment shall be provided with leak detection, isolation, and containment capabilities having redundancy, reliability, and performance capabilities which reflect the importance to safety of isolating these piping systems. Such piping systems shall be designed with a capability to test periodically the operability of the isolation valves and associated apparatus and to determine if valve leakage is within acceptable limits.

GDC 56, Primary Containment Isolation, describes the isolation provisions that must be provided for lines that connect directly to the containment atmosphere and which penetrate primary reactor containment unless it can be demonstrated that the isolation provisions for a specific class of lines are acceptable on some other defined basis.

GDC 61, Fuel Storage and Handling and Radioactivity Control, requires that the fuel storage and handling, radioactive waste, and other systems which may contain radioactivity shall be designed to assure adequate safety under normal and postulated accident conditions.

The assumptions and results of the FHA analyses, coupled with the proposed TS changes comply with the above GDCs.

St. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 L-2002-089 Attachment 1 Page 10 Conclusions Based on review of the licensing bases documentation and the results of the St. Lucie Unit 1 and Unit 2 FHA analyses, it is concluded that the proposed license amendments are acceptable and that code requirements are maintained.

St. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 L-2002-089 Attachment 2 Page 1 ATTACHMENT 2 DETERMINATION OF NO SIGNIFICANT HAZARDS CONSIDERATION Introduction Florida Power and Light Company (FPL) proposes to revise the St. Lucie Units 1 and 2 Technical Specifications (TS) to incorporate line item improvements associated with the handling of recently irradiated fuel assemblies in accordance with Revision 2 of NUREG-1432, Standard Technical Specifications Combustion Engineering Plants (STS) and TSTF-51, Revision 2. The STS remove the applicability of TSs regarding operability of certain systems (containment penetrations, spent fuel pool and shield building ventilation, and containment isolation) when handling fuel assemblies that have decayed a sufficient period of time such that dose consequences for the postulated fuel handling accident (FHA) remain below the limits of the NRC Standard Review Plan (SRP) when these systems are not available. The design bases FHA analyses for St. Lucie Unit 1 and Unit 2 are based on a fission product inventory that has decayed 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. Further, these FHA analyses do not credit the subject systems and rely on decay of fission product inventory to ensure that dose consequences remain below SRP limits. Therefore, the TSs that pertain to these systems during fuel handling can be revised to limit their applicability to recently irradiated fuel assemblies, where 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 /> without impacting the analyses. Partial implementation of the STS criteria was applied to containment penetration specifications during refueling by License Amendments 172 and 120 for Unit 1 and Unit 2, respectively. The proposed amendments would incorporate the remaining applicable line item improvements and provide consistency between the two St. Lucie units.

Determination of No Significant Hazards Consideration The standards used to arrive at a determination that a request for amendment involves a no significant hazards consideration are included in the Commission's regulation, 10 CFR 50.92, which states that no significant hazards considerations are involved if the operation of the facility in accordance with the proposed amendments would not (1) involve a significant increase in the probability or consequences of an accident previously evaluated; or (2) create the possibility of a new or different kind of accident from any accident previously evaluated; or (3) involve a significant reduction in a margin of safety.

Each standard is discussed as follows:

St. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 L-2002-089 Attachment 2 Page 2 (1)

Operation of the facility in accordance with the proposed amendments would not involve a significant increase in the probability or consequences of an accident previously evaluated.

The proposed changes to the St. Lucie Units 1 and 2 TSs incorporate line item improvements that are based on assumptions in the postulated fuel handling accident analyses. These proposed changes remove the applicability of TSs regarding operability of certain systems (containment penetrations, spent fuel pool and shield building ventilation, and containment isolation) when handling fuel assemblies that have decayed a sufficient period of time. The results of the FHA analyses demonstrate that sufficient radioactive decay has occurred after 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> such that the resulting dose consequences are well within the limits given in 10 CFR 100 and within the limits given in the Standard Review Plan, NUREG-0800.

The systems that have been included in these proposed changes will have administrative controls in place to assure that systems are available and can be promptly returned to operation to further reduce dose consequences.

These administrative controls will include a single normal or contingency method to promptly close the primary or secondary containment penetrations. 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 FHA such that it can be treated and monitored. This will result in lower doses than those calculated for the FHA.

The equipment or systems involved are not initiators of an accident. Operability of these systems or equipment during fuel movement and/or core alterations has no affect on the probability of any accident previously evaluated.

The proposed changes do not significantly increase the consequences of a fuel handling accident as previously evaluated. The calculated doses are well within the limits given in 10 CFR Part 100 and within the limits given in the Standard Review Plan, NUREG-0800. In addition, the calculated doses are larger than the expected doses because the calculations do not credit any filtration or containment of the source term that will occur by the administrative controls that will be in place.

The changes being proposed do not affect assumptions contained in other plant safety analyses or the physical design of the plant, nor do they affect other TSs that preserve safety analysis assumptions.

Therefore, operation of the facility in accordance with the proposed amendments would not involve a significant increase in the probability or consequences of an accident previously analyzed.

St. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 L-2002-089 Attachment 2 Page 3 (2)

Operation of the facility in accordance with the proposed amendments would not create the possibility of a new or different kind of accident from any accidents previously evaluated.

The proposed changes to the TSs do not affect or create a different type of fuel handling accident. The fuel handling accident analyses assume that all of the iodine and noble gases that become airborne, escape, and reach the exclusion area boundary and low population zone with no credit taken for filtration, containment of the source term, or for decay or deposition. The proposed changes do not involve the addition or modification of equipment nor do they alter the design of plant systems. The revised operations are consistent with the fuel handling accident analyses. Therefore, the proposed changes do not create the possibility of a new or different kind of accident from any accident previously evaluated.

(3)

Operation of the facility in accordance with the proposed amendments would not involve a significant reduction in a margin of safety.

The calculated doses are well within the limits given in 10 CFR Part 100 and within the limits given in the Standard Review Plan, NUREG-0800.

The proposed changes do not alter the bases for assurance that safety-related activities are performed correctly or the basis for any TS that is related to the establishment of or maintenance of a safety margin.

The systems that have been included in the proposed change will have administrative controls in place to assure that the systems are available and can be promptly returned to operation to further reduce dose consequences.

These administrative controls will include a single normal or contingency method to promptly close the primary or secondary containment penetrations. 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 FHA such that it can be treated and monitored.

Therefore, operation of the facility in accordance with the proposed amendments would not involve a significant reduction in a margin of safety.

Based on the above, we have determined that the proposed amendments do not (1) involve a significant increase in the probability or consequences of an accident previously evaluated, (2) create the possibility of a new or different kind of accident from any accident previously evaluated, or (3) involve a significant reduction in a margin of safety; and therefore, do not involve a significant hazards consideration as defined in 10 CFR 50.92.

St. Lucie Units 1 and 2 Docket Nos. 50-335 and 50-389 L-2002-089 Attachment 2 Page 4 Environmental Impact Consideration Determination The proposed license amendments change requirements with respect to installation or use of facility components located within the restricted area as defined in 10 CFR Part 20. The proposed amendments involve no significant increase in the amounts and no significant change in the types of any effluents that may be released offsite, and no significant increase in individual or cumulative occupational radiation exposure. FPL has concluded that the proposed amendments involve no significant hazards consideration, and therefore, meet the criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b), an environmental impact statement or environmental assessment need not be prepared in connection with issuance of the amendments.

ST. LUCIE UNIT 2 314.9 REFUELING OPERATIONS (continued)

BASES (continued) 3/4.9.8 SHUTDOWN COOLING AND COOLANT CIRCULATION (continued)

The requirement to have two shutdown cooling loops OPERABLE when there is less than 23 feet of water above the reactor pressure vessel flange with irradiated fuel in the core ensures that a single failure of the operating shutdown cooling loop will not result in a complete loss of decay heat removal capability. With the reactor vessel head removed and 23 feet of water above the reactor pressure vessel flange with irradiated fuel in the core, a large heat sink is available for core cooling, thus in the event of a failure of the operating shutdown cooling loop, adequate time is provided to initiate emergency procedures to cool the core.

The footnote providing for a minimum reactor coolant flow rate of

>1850 gpm considers one of the two RCS injection points for a SDCS train to be isolated. The specified parameters include 50 gpm for flow measurement uncertainty, and 3°F uncertainty for RCS and CCW temperature measurements. The conditions of minimum shutdown time, maximum RCS temperature, and maximum temperature of CCW to the shutdown cooling heat exchanger are initial conditions specified to assure that a reduction in flow rate from 3000 gpm to 1800 gpm will not result in a temperature transient exceeding 140OF during conditions when the RCS water level is at an elevation > 29.5 feet.

314.9.9 CONTAINMENT ISOLATION SYSTEM The OPERABILITY of this system ensures that the containment isolation valves will be automatically isolated upon detection of high radiation levels within the containment. The OPERABILITY of this system is required to restrict the release of radioactive material from the containment atmosphere to the environment.
