Attachment 1, Volume 12, Rev. 0, Page 6 of 161 DISCUSSION OF CHANGES ITS 3.7.1, RESIDUAL HEAT REMOVAL SERVICE WATER (RHRSW) SYSTEM ADMINISTRATIVE CHANGES A.1 In the conversion of the Monticello Current Technical Specifications (CTS) to the plant specific Improved Technical Specifications (ITS), certain changes (wording preferences, editorial changes, reformatting, revised numbering, etc.) are made to obtain consistency with NUREG-1433, Rev. 3, "Standard Technical Specifications General Electric Plants, BWR/4" (ISTS). These changes are designated as administrative changes and are acceptable because they do not result in technical changes to the CTS. MORE RESTRICTIVE CHANGES M.1 CTS 3.5.C.1 is applicable whenever irradiated fuel is in the reactor vessel and reactor water temperature is greater than 212 0F. ITS LCO 3.7.1 is applicable in MODES 1, 2, and 3. This changes the CTS by requiring two RHRSW subsystems to be OPERABLE in MODE 2 when reactor water temperature is less than or equal to 212 0F. The purpose of CTS 3.5.C.1 is to ensure the RHRSW subsystems are OPERABLE to mitigate the consequences of a design basis accident. The RHRSW subsystems are required to be OPERABLE during MODES 1, 2, and 3 when there is considerable energy in the reactor core and a DBA could cause a significant heat up of the suppression pool. In MODES 1 and 3, the reactor coolant temperature will always be above 212 0 F. In MODE 2, the reactor coolant temperature may be less than or equal to 2120 F when the reactor is subcritical but control rods are withdrawn. Therefore, it is necessary and acceptable to require the RHRSW subsystems to be OPERABLE. This change is designated as more restrictive because the LCO will be applicable under more reactor operating conditions than in the CTS. M.2 Currently, the CTS does not provide any specific Surveillances to verify OPERABILITY of the RHRSW subsystems. ITS SR 3.7.1.1 requires verification that each RHRSW subsystem manual, power operated, and automatic valve in the flow path that is not locked, sealed, or otherwise secured in position is in the correct position or can be aligned to the correct position every 31 days. This changes the CTS by adding this Surveillance Requirement to the Technical Specifications. The purpose of ITS SR 3.7.1.1 is to provide assurance that the proper flow paths will exist for RHRSW System operation. This change is acceptable because it provides additional assurance that the RHRSW System will be capable of performing its function. This change is designated as more restrictive because it adds Surveillance Requirements to the CTS.

Attachment 1, Volume 12, Rev. 0, Page 7 of 161 DISCUSSION OF CHANGES ITS 3.7.1, RESIDUAL HEAT REMOVAL SERVICE WATER (RHRSW) SYSTEM REMOVED DETAIL CHANGES LA.1 (Type I - Removing Details of System Design and System Description, Including Design Limits) CTS 3.5.C.1 states that an RHRSW subsystem consists of the following equipment powered from one division: 1 RHR Heat Exchanger, 1 RHR Service Water Pump, and valves and piping necessary for torus cooling. ITS 3.7.1 requires two RHRSW subsystems to be OPERABLE, but the details of what constitutes an OPERABLE subsystem are moved to the Bases. This changes the CTS by moving the details of what constitutes an OPERABLE subsystem to the Bases. The removal of these details, which are related to system design, from the Technical Specifications is acceptable because this type of information is not necessary to be included in the Technical Specifications to provide adequate protection of public health and safety. The ITS still retains the requirement for two RHR service water subsystems to be OPERABLE. Also, this change is acceptable because the removed information will be adequately controlled in the ITS Bases. Changes to the Bases are controlled by the Technical Specification Bases Control Program in Chapter 5 of the ITS. This program provides for the evaluation of changes to ensure ihe Bases are properly controlled. This change is designated as a less restrictive removal of detail change because information relating to system design is being removed from the Technical Specifications. LESS RESTRICTIVE CHANGES L.1 (Category 4 - Relaxation of Required Action) When two RHRSW subsystems are inoperable, a unit shutdown is required by CTS 3.5.C.3; no time is provided to restore a subsystem prior to requiring the unit shutdown. With two RHRSW subsystems inoperable, ITS 3.7.1 ACTION B will allow 8 hours to restore one inoperable RHRSW subsystem prior to requiring a unit shutdown. This changes the CTS by allowing 8 hours to restore one of two inoperable RHRSW subsystems prior to requiring a unit shutdown. The purpose of CTS 3.5.C is to require sufficient containment cooling to ensure the primary containment conditions for the safety analyses are met. The proposed 8 hour Completion Time is acceptable since an immediate shutdown has the potential to result in a unit scram and discharge of steam to the suppression pool, when both RHRSW subsystems are inoperable and incapable of removing the generated heat. The 8 hours provides some time to restore one of the subsystems prior to requiring a shutdown (thus precluding the potential problem described above), yet is short enough that it does not significantly increase the probability of an accident to occur during this additional time. This change is designated as less restrictive because less stringent Required Actions are being applied in the ITS than were applied in the CTS. L.2 (Category 3 - Relaxation of Completion Time) CTS 3.5.C.3 requires the unit to be shutdown and reactor water temperature reduced to less than 21 20 F within 24 hours if the requirements of CTS 3.5.C.1 or CTS 3.5.C.2 are not met. ITS 3.7.1 ACTION C requires the reactor be in MODE 3 in 12 hours and in MODE 4 in 36 hours. This changes the CTS by requiring the unit to be in Monticello Page 2 of 3 Attachment 1, Volume 12, Rev. 0, Page 7 of 161

Attachment 1, Volume 12, Rev. 0, Page 8 of 161 DISCUSSION OF CHANGES ITS 3.7.1, RESIDUAL HEAT REMOVAL SERVICE WATER (RHRSW) SYSTEM MODE 3 in 12 hours and by extending the time to reduce reactor water temperature to < 212 0 F (i.e., MODE 4) from 24 hours to 36 hours. The purpose of CTS 3.5.C.3 is to place the unit outside the Applicability of the Specification within a reasonable amount of time. This change is acceptable because the Completion Time is consistent with the safe operation under the specified Condition, considering the OPERABLE status of the redundant systems or features. This includes the capacity and capability of remaining systems or features, a reasonable time for repairs or replacement, and the low probability of a DBA occurring during the allowed Completion Time. The allowed Completion Times are reasonable, based on operating experience, to reach the required unit conditions from full power conditions in an orderly manner and without challenging unit systems. This change is also acceptable because it requires the unit to be in an intermediate condition (MODE 3) sooner than is currently required (12 hours versus 24 hours). This portion of the change reduces the amount of time the unit would be allowed to continue to operate in MODES 1 and 2 once the condition is identified. The consequences of a pressurization event are significantly reduced when the reactor is shutdown and a controlled cooldown is already in progress. This change is designated as less restrictive because additional time is allowed to place the unit outside the LCO Applicability than is allowed in the CTS.

1. ISTS 3.7.1 ACTIONS A and B have been deleted because they are not applicable to Monticello. The Monticello USAR, Section 5.2.3.2.3 (for the long term primary containment response after a design basis loss of coolant accident analysis) only credits one RHRSW pump in one subsystem (i.e., a flow rate of 3500 gpm, which is the flow rate for one RHRSW pump). The following requirements have been renumbered, where applicable, to reflect this deletion.
2. Changes have been made to reflect changes made to other Specifications.
3. The brackets have been removed and the proper plant specific information/value has been provided.

The RHRSW System is operated whenever the RHR heat exchangers are required to operate in the shutdown cooling mode r3flin I modesthe suppression pool coolingor spray mode of the RHR System. Q The RHRSW System consists of two independent and redundant%-f subsystems. Each subsystem is made up of a header, two m gpm pumps, a suction source, valves, piping, heat exchanger, and associated instrumentation. Either of the two subsystems is capable of providing the required cooling capacity with one pump operating to maintain safe manual 1 Inch shutdown conditions. The two subsystems are separated from each normally close cross tie valved, so that failure of This 1 inch cross tie lins one subsystem will not affect the OPERABILITY of the other subsystem. > (ID Installed between the two The RHRSW System is designed with sufficient redundancy so that no J subsystems to allow both subsystems to be single active component failure can prevent it from achieving its design pressurizedbyoneoperating function.

If operating during a loss of coolant accident (LOCA), the system is automatically (i2 tripped to allow thi'diesel generators to automatically power only that equipment necessary to reflood the core. The system can be manually started mnuteath A, or manetad any time the LOCA signal is manually overridden or clears. APPLICABLE The RHRSW System removes heat from the suppression pool to limit the SAFETY suppression pool temperature and primary containment pressure ANALYSES following a LOCA. This ensures that the primary containment can perform its function of limiting the release of radioactive materials to the environment following a LOCA. The ability of the RHRSW System to support long term cooling of the reactor or primary containment is BWR/4 STS B 3.7.1-1 Rev. 3.0, 03/31/04 Attachment 1, Volume 12, Rev. 0, Page 14 of 161

Attachment 1, Volume 12, Rev. 0, Page 17 of 161 RHRSW System B 3.7.1 BASES APPLICABILITY In MODES 1, 2, and 3, the RHRSW System is required to be OPERABLE to support the OPERABILITY of the RHR System for primary containment cooling (LCO 3.6.2.3, "Residual Heat Removal (RHR) Suppression Pool and therefore, the requirements are not the same for all facets of Coolingm _ "-kni _ _ _ __ (R_____ edo gpr,3 ) and decay heat removal (LCO 3.4."'Residual Heat __oval C nI 0 operatoninMODES4 Removal (RHR) Shutdown Cooling System - Hot Shutdown"). The and s. The LCOs of the system supported by the Applicability is therefore consistent with the requirements rqieet of these RHRSW System wilt systems. govern RHRSW System OPERABILITY In MODES 4 and 5, the OPERABILITY requirementsof the RHRSW requirements In MODES System are determined by the systems it supports. 0 ACTIONS A.1 With one RHRSW ump inoperable, the in perable pump must be restored to OPE LE status within 30 ys. With the unit in this condition, the re ining OPERABLE RH SW pumps are adequate to perform the RH W heat removal funct n. However, the overall reliability is redu ed because a single f ilure in the OPERABLE subsystem cou result in reduced RHISW capability. The 30 day Completion Ti e is based on the rem ining RHRSW heat removal 0 capability, inc ding enhanced reliabipty afforded by manual cross connect cap ility, and the low prob bility of a DBA with concurre worst case single ilure. B.1 With on RHRSW pump inoper ble in each subsystem, if no dditional failures ccur in the RHRSW stem, and the two OPERAB pumps are ali ned by opening the no mally closed cross tie valves, hen the remali ng QPERABLE pump and flow paths provide adeq ate heat remo al capacity following a/design basis LOCA. Howeve capability for this lignment is not assumed in long term containment re ponse analysis and an additional single fai ure in the RHRSW System co Id reduce the sy em capacity below th assumed in the safety analy is. Therefore, c tinued operation is pe mitted only for a limited time. One inoperable ppmp is required to be r stored to OPERABLE status ithin 7 days. The day Completion Time/or restoring one inoperable R RSW pump to PERABLE status is b sed on engineering judgment considering the level of redundancy provided.

Attachment 1, Volume 12, Rev. 0, Page 18 of 161 RHRSW System B 3.7.1 BASES ACTIONS (continued) Required Action 1 is intended to handle the inoperability of one RHRSW subsystem e .an The Completion Time of 7 days is allowed to restore the RHRSW subsystem to OPERABLE status. With the unit in this condition, the remaining OPERABLE RHRSW subsystem is adequate to perform the RHRSW heat removal function. However, the overall reliability is reduced because a single failure in the OPERABLE RHRSW subsystem could result in loss of RHRSW function. The Completion Time is based on the redundant RHRSW capabilities afforded by the OPERABLE subsystem and the low probability of an event occurring requiring RHRSW during this period. The Re~quiread Action isrmodified by 'a Note'indicating that the applicable - Conditions of LCO 3.4J, be entered and Required Actions taken if the YU inoperable RHRSW subsystem results in inoperableTRHR shutdown cooling. This is an exception to LCO 3.0.6 and ensures the proper actions are taken for these components. With both RHRSW subsystems inoperablelfor reasons other that Condition B (e.g. subsystemsw noperable flow , or one subsysterg~wtnan ino eralump and one subsiha ino e flow pathF,the RHRSW System is not capable of performing its intended function. At least one subsystem must be restored to OPERABLE status within 8 hours. The 8 hour Completion Time for restoring one RHRSW subsystem to OPERABLE status, is based on the Com letion Times provided for the RHR suppression pool cooling !MdII M~functions. The Required Action is modified by a Note indicating that the applicable Conditions of LCO 3.4, be entered and Required Actions taken if the inoperable RHRSW subsystem results in inoperable MRHR shutdown coolingl. This is an exception to LCO 3.0.6 and ensures the proper (D actions are taken for these components. BWRI4 STS B 3.7.1-4 Rev. 3.0, 03/31/04 Attachment 1, Volume 12, Rev. 0, Page 18 of 161

To achieve this status, the unit must be placed in at least MODE 3 within 12 hours and in MODE 4 within 36 hours. The allowed Completion Times are reasonable, based on operating experience, to reach the required unit conditions from full power conditions in an orderly manner and without challenging unit systems.

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

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

Attachment 1, Volume 12, Rev. 0, Page 26 of 161 DISCUSSION OF CHANGES ITS 3.7.2, EMERGENCY SERVICE WATER (ESW) AND ULTIMATE HEAT SINK (UHS) ADMINISTRATIVE CHANGES None MORE RESTRICTIVE CHANGES M.1 The CTS does not have any specific requirements for the Emergency Service Water (ESW) System or ultimate heat sink (UHS). The ESW System and UHS requirements are governed by the systems they support. ITS LCO 3.7.2 requires two ESW subsystems and the UHS to be OPERABLE. Appropriate ACTIONS and Surveillance Requirements are also provided. This changes the CTS by incorporating the requirements of ITS 3.7.2. The ESW System and UHS are necessary to support the equipment required for long term cooling of the reactor containment following a Design Basis Accident (DBA). The requirement to maintain two ESW subsystems and the UHS OPERABLE assures adequate cooling capacity is available for the removal of heat from equipment such as residual heat removal and core spray pump coolers, and ECCS room coolers required for safe shutdown following a DBA. The ESW System, together with the UHS satisfies Criterion 3 of 10 CFR 50.36(c)(2)(ii). This change is acceptable because the ability of the ESW System to provide adequate cooling to the identified safety equipment is an implicit assumption for the safety analysis evaluated for a DBA. The ITS restoration actions for when an ESW subsystem or the UHS is inoperable is consistent with or more restrictive than the Technical Specification Systems they support. In addition, specific temperature and level requirements are now specified, as well as Surveillance Requirements. This change is designated as more restrictive because it adds new requirements to the CTS.

1. The brackets have been removed and the proper plant specific information/value has been provided.
2. ISTS 3.7.2 ACTIONS A and B have been deleted because they are not applicable to Monticello. The Monticello ESW System design contains only one ESW pump per subsystem.
3. The bracketed ISTS 3.7.2 ACTION C has been deleted because it is not applicable to Monticello. Monticello does not include cooling towers for OPERABILITY of the ESW System or UHS.
4. The bracketed ISTS ACTION D has been deleted as it is not part of the plant specific ITS. The 900 F limit in ITS SR 3.7.2.2 is the maximum water temperature assumed in the accident analysis. Therefore, when 900 F is exceeded, the UHS is inoperable and ISTS 3.7.2 ACTION F (ITS 3.7.2 ACTION B) must be taken. The following requirements have been renumbered to reflect this and other ACTION deletions.
5. ISTS 3.7.2 Required Action E.1 Note 1 has been deleted because it is not applicable to Monticello. The Emergency Diesel Generator-Emergency Service Water System provides the Monticello emergency diesel generator cooling water. The following Note has been renumbered to reflect this deletion.
6. Changes have been made to reflect changes made to other Specifications.
7. The ISTS 3.7.2 Required Action E.1 Completion Time has been changed from 72 hours to 7 days. The requirement for 72 hours was based on the more limiting Completion Time associated with restoring an inoperable DG. The Monticello EDGs are supported by the EDG-ESW system. The Completion Time has been revised to be consistent with the time provided to restore an inoperable RHR and core spray subsystem, which are the subsystems supported by the ESW System.
8. Each ESW subsystem includes both manual and automatic valves. There are no power operated valves other than automatic valves: therefore, reference to "power operated" valves in ISTS SR 3.7.2.5 (ITS SR 3.7.2.3) has been deleted.

Attachment 1, Volume 12, Rev. 0, Page 47 of 161 DISCUSSION OF CHANGES ITS 3.7.3, EMERGENCY DIESEL GENERATOR-EMERGENCY SERVICE WATER (EDG-ESW) SYSTEM ADMINISTRATIVE CHANGES None MORE RESTRICTIVE CHANGES. M.1 The CTS does not have any specific requirements for the Emergency Diesel Generator-Emergency Service Water (EDG-ESW) System. The EDG-ESW System requirements are governed by the EDG Technical Specifications. ITS LCO 3.7.3 requires two EDG-ESW subsystems to be OPERABLE. An appropriate ACTION and Surveillance Requirements are also provided. This changes the CTS by incorporating the requirements of ITS 3.7.3. The EDG-ESW System is necessary to support the emergency diesel generator requirement following a Design Basis Accident (DBA). The requirement to maintain two EDG-ESW subsystems OPERABLE assures adequate cooling capacity is available for the removal of heat from the emergency diesel generators required for safe shutdown following a DBA. The EDG-ESW System satisfies Criterion 3 of 10 CFR 50.36(c)(2)(ii). This change is acceptable because the ability of the EDG-ESW System to provide adequate cooling to the emergency diesel generators is an implicit assumption for the safety analysis evaluated for a DBA. The ITS restoration actions for when an EDG-ESW subsystem is inoperable is consistent with the EDG CTS Actions, since the ITS requires the associated EDG to be declared inoperable. In addition, specific Surveillance requirements are now specified. This change is designated as more restrictive because it adds new requirements to the CTS.

Attachment 1, Volume 12, Rev. 0, Page 51 of 161 JUSTIFICATION FOR DEVIATIONS ITS 3.7.3, EMERGENCY DIESEL GENERATOR-EMERGENCY SERVICE WATER (EDG-ESW) SYSTEM

1. The brackets have been removed and the proper plant specific information/value has been provided.
2. ISTS 3.7.3 Required Actions A.1, A.2 and A.3 have been deleted because they are not applicable to Monticello. The Monticello EDG-ESW System design does not provide for credited alternate cooling sources. In addition, ISTS 3.7.3 Condition B has been deleted to reflect the ISTS 3.7.3 ACTION A requirements for inoperability of one or more EDG-ESW subsystems. The following requirements have been renumbered, where applicable, to reflect this deletion.
3. ISTS 3.7.3 provides the cooling water requirement for the DG I B SSW System. This Specification was a plant-specific Specification, written for the E. I. Hatch Units 1 and 2 design. Hatch Units I and 2 design includes a SSW System for the common DG (1B DG), separate from the cooling water for the remaining DGs. ISTS 3.7.2, Plant Service Water (PSW) System and Ultimate Heat Sink (UHS) provided the cooling water requirement for the remaining DGs. This is shown in the ISTS 3.7.2 Bases, Background section, which states that the PSW System provides cooling water for.

the removal of heat from equipment, such as the DGs. The ISTS 3.7.2 Applicability is MODES 1, 2, and 3. As stated in the ISTS 3.7.2 Bases, Applicability section, the MODES 4 and 5 OPERABILITY requirements of the PSW System and UHS are determined by the systems they support. Thus, for all DGs except the common 1B DG, no specific PSW requirements are provided in the ISTS for MODES other than MODES 1, 2, and 3. In addition, NUREG-1431, Rev.3, the Westinghouse ISTS, the ISTS includes only MODES 1, 2, 3, and 4 (which is equivalent to the BWR MODES 1, 2, and 3) for the DG cooling water Specification (ISTS 3.7.6, Service Water System). The Monticello design includes an EDG-ESW System that only provides cooling water to the EDGs. Therefore, consistent with the ISTS intent, the Applicability for ISTS 3.7.3 (ITS 3.7.3) has been changed to MODES 1, 2, and 3.

4. Each EDG-ESW subsystem includes only manual valves. There are no power operated or automatic valves; therefore, reference to "power operated" and "automatic" valves in ISTS SR 3.7.3.1 has been deleted.
5. An ACTIONS Note has been added to ISTS 3.7.3 (ITS 3.7.3) to allow separate Condition entry for each inoperable EDG-ESW subsystem. This change is intended to ensure that each occurrence of an inoperable EDG-ESW subsystem be assessed in accordance with the applicable Conditions and Required Actions of LCO 3.8.1 for its impact on the EDG capability to function as an AC power source. This change is acceptable since the ITS 3.7.3 Required Action is to declare the associated EDG inoperable.

Attachment 1, Volume 12, Rev. 0, Page 54 of 161 B 3.7.3 Q INSERT I In addition, the Service Water System to EDG-ESW System isolation valves open upon receipt of an associated EDG start signal. If offsite power is not lost, then the Service Water System will supply cooling water to the associated EDG (i.e., the EDG-ESW and Service Water pumps are in parallel, and the discharge pressure of the Service Water pump is higher than the EDG-ESW pump). However, the Service Water System capability is not required to be OPERABLE as part of this Specification. Q' INSERT IA The EDG-ESW subsystems are independent of each other to the degree that each has separate controls, power supplies, and the operation of one subsystem does not depend on the other subsystem. In the event of a DBA, one EDG-ESW subsystem is required to provide the minimum heat removal capability assumed in the safety analysis for the associated EDG. To ensure this requirement is met, two EDG-ESW subsystems must be OPERABLE. At least one subsystem will operate, if the worst single active failure occurs coincident with the loss of offsite power. A subsystem is considered OPERABLE when it has an OPERABLE pump and an OPERABLE flow path capable of taking suction from the intake structure and transferring the water to the associated EDG. Q INSERT2 In MODES 1,2, and 3, the EDG-ESW System is required to be OPERABLE to support OPERABILITY of the EDGs. Therefore, the EDG-ESW System is required to be OPERABLE in these MODES. In MODES 4 and 5, the OPERABILITY requirements of the EDG-ESW System are determined by the systems it supports. Therefore, the requirements are not the same for all facets of operation in MODES 4 and 5. LCO 3.8.2, 'AC Sources - Shutdown," will govern EDG-ESW System OPERABILITY requirements in MODES 4 and 5.

Section 1.3, Completion Times, specifies once a Condition has been entered, subsequent divisions, subsystems, components or variables expressed in the Condition, discovered to be inoperable or not within limits, will not result in separate entry into the Condition. Section 1.3 also specifies Required Actions of the Condition continue to apply for each additional failure, with Completion Times based on initial entry into the Condition. However, the Required Actions for inoperable EDG-ESW subsystems provide appropriate compensatory measures for separate inoperable EDG-ESW subsystems. As such, a Note has been provided that allows separate Condition entry for each inoperable EDG-ESW subsystem. Insert Page B 3.7.3-2 Attachment 1, Volume 12, Rev. 0, Page 56 of 161

Attachment 1, Volume 12, Rev. 0, Page 68 of 161 DISCUSSION OF CHANGES ITS 3.7.4, CONTROL ROOM EMERGENCY FILTRATION (CREF) SYSTEM ADMINISTRATIVE CHANGES A.1 In the conversion of the Monticello Current Technical Specifications (CTS) to the plant specific Improved Technical Specifications (ITS), certain changes (wording preferences, editorial changes, reformatting, revised numbering, etc.) are made to obtain consistency with NUREG-1433, Rev. 3, "Standard Technical Specifications General Electric Plants, BWR/4" (ISTS). These changes are designated as administrative changes and are acceptable because they do not result in technical changes to the CTS. A.2 CTS 4.1 7.B.1 states to operate each CREF subsystem for at least 10 hours with the heaters "operable." ITS SR 3.7.4.1 requires the CREF System to operate with the heaters "operating." This changes the CTS by requiring the CREF heaters to be "operating" in lieu of being "operable" during the test. The purpose of CTS 4.17.B.1 is to ensure each CREF subsystem remains OPERABLE to support the safety analyses. This change requires the CREF heaters to be "operating" in lieu of being "operable" during the test. Moisture may accumulate on the high efficiency particulate air filters and the charcoal adsorber when the system is in standby. Performing this Surveillance on a periodic frequency will remove the moisture since it is necessary for the heaters to actually operate to reduce moisture from the adsorbers and HEPA filters. Therefore it is necessary that the heaters are actually operating during the test. This change is consistent with current practice. The heaters are still required to be OPERABLE, as required by ITS SR 3.7.4.2 and ITS 5.5.6, Ventilation Filter Testing Program (VFTP). This change is designated as administrative because it does not result in technical changes to the CTS. A.3 Under certain conditions, CTS 3.17.B.1.c and 3.17.B.1 .d, in part, require the immediate suspension of movement of recently irradiated fuel assemblies in the secondary containment. ITS 3.7.4 ACTIONS D and F include the same requirement, however a Note has been added that states that LCO 3.0.3 is not applicable. This changes the CTS by adding this Note. The purpose of CTS 3.17.B.1.c and 3.17.B.1.d, in part, is to provide the appropriate actions when one or two CREF subsystems, as applicable, are inoperable while moving recently irradiated fuel in the secondary containment. This change adds a Note that states LCO 3.0.3 is not applicable. This Note has been added because ITS LCO 3.0.3 has been added to ITS Section 3.0 in accordance with ITS Section 3.0 DOC M.1. This Note is necessary because if moving recently irradiated fuel assemblies while in MODE 4 or 5, LCO 3.0.3 would not specify any action. If moving recently irradiated fuel assemblies while in MODE 1, 2, or 3, the fuel movement is independent of reactor operations. Therefore, in either case, inability to suspend movement of recently irradiated fuel assemblies would not be a sufficient reason to require a reactor shutdown. Since ITS LCO 3.0.3 is not currently included in the CTS this change is considered administrative. This change is designated as administrative because it does not result in technical changes to the CTS. Monticello Page 1 of 7 Attachment 1, Volume 12, Rev. 0, Page 68 of 161

Attachment 1, Volume 12, Rev. 0, Page 69 of 161 DISCUSSION OF CHANGES ITS 3.7.4, CONTROL ROOM EMERGENCY FILTRATION (CREF) SYSTEM A.4 CTS 3/4.17.B.2 specifies the performance requirements for the CREF subsystems while CTS 3/4.17.B.3 specifies the post maintenance requirements for the CREF subsystems. ITS SR 3.7.4.2 requires the performance of the required CREF filter testing in accordance with the Ventilation Filter Testing Program (VFTP). CTS 314.17.B does not include a VFTP, but the requirements that make up the program are being moved to ITS 5.5. This changes the CTS by requiring testing in accordance with the VFTP, whose requirements are being moved to ITS 5.5. This change is acceptable because filter testing requirements are being moved to the VFTP as part of ITS 5.5 and ITS SR 3.7.4.2 references the VFTP for performing these tests. This change is.designated as administrative because it does not result in technical changes to the CTS. A.5 CTS 4.17.B.2.c requires verification of the OPERABILITY of each CREF subsystem each "operating cycle." ITS SR 3.7.4.3 and ITS SR 3.7.4.4 require the same testing however the Surveillances are required to be performed every "24 months." This changes the CTS by changing the Frequency from "operating cycle" to "24 months." This change is acceptable because the current "operating cycle" is "24 months." In letter L-MT-04-036, from Thomas J. Palmisano (NMC) to the USNRC, dated June 30, 2004, NMC has proposed to extend the fuel cycle from 18 to 24 months and the same time has performed an evaluation in accordance with Generic Letter 91-04 to extend the unit Surveillance Requirements from 18 months to 24 months. 4.17.B.2.c was included in this evaluation. This change is designated as administrative because it does not result in any technical changes to the CTS. A.6 These changes to CTS 3.17.B.1, CTS 3.17.B.1.c, and CTS 3.17.B.1.d are provided in the Monticello ITS consistent with the Technical Specifications Change Request submitted to the USNRC for approval in NMC letter L-MT-04-023, from Thomas J. Palmisano (NMC) to USNRC, dated April 29, 2004. As such, these changes are administrative. A.7 This change to CTS 4.17.B.2.c is provided in the Monticello ITS consistent with the Technical Specifications Change Request submitted to the USNRC for approval in NMC letter L-MT-04-036, from Thomas J. Palmisano (NMC) to USNRC, dated June 30, 2004. As such, this change is administrative. MORE RESTRICTIVE CHANGES M.1 CTS 3.17.B.1, is applicable, in part, whenever irradiated fuel is in the reactor vessel and reactor water temperature is greater than 2120 F. ITS LCO 3.7.4 is applicable in MODES 1, 2, and 3. This changes the CTS by requiring the CREF System to be OPERABLE in MODE 2 when reactor water temperature is less than or equal to 212 0 F. Monticello Page 2 of 7 Attachment 1, Volume 12, Rev. 0, Page 69 of 161

Attachment 1, Volume 12, Rev. 0, Page 70 of 161 DISCUSSION OF CHANGES ITS 3.7.4, CONTROL ROOM EMERGENCY FILTRATION (CREF) SYSTEM The purpose of CTS 3.17.B.1 is to ensure the CREF System is OPERABLE to mitigate the consequences of a design basis accident. The CREF System is required to be OPERABLE during MODES 1, 2, and 3 when there is considerable energy in the reactor core or there is a potential for the reactor core to become critical and the CREF System would be required to mitigate the consequences of a design basis accident. In MODES 1 and 3, the reactor coolant temperature will always be above 212 0F. In MODE 2, the reactor coolant temperature may be less than or equal to 2120 F when the reactor is subcritical but control rods are withdrawn. Therefore, it is necessary and acceptable to require the CREF System to be OPERABLE. This change is designated as more restrictive because the LCO will be applicable under more reactor operating conditions than in the CTS. M.2 CTS 3.17.B.1.a allows 7 days to restore an inoperable CREF subsystem. If this cannot be met, it requires the unit to be in hot shutdown (i.e., MODE 3) in 12 hours and to be below 2120 F (i.e., be in MODE 4) or initiate and maintain the OPERABLE CREF subsystem in the pressurization mode within the following 24 hours. ITS 3.7.4 ACTION C does not include the option to place the OPERABLE CREF subsystem in operation in lieu of being in MODE 4. This changes the CTS by deleting the allowance'to place the OPERABLE CREF subsystem in operation in lieu of achieving MODE 4 conditions. The purpose of the 3.17.B.1.a, in part, is to place the unit in a MODE in which the LCO is no longer applicable in a reasonable amount of time. ITS 3.7.4 ACTION C does not include the option to place the OPERABLE CREF subsystem in operation. ITS 3.7.4 ACTION C requires the unit to be in MODE 3 in 12 hours and MODE 4 in 36 hours. This change deletes the allowance to place the OPERABLE CREF subsystem in operation and continue to operate in MODE 3. CTS 3.17.B.1 allows the unit to operate in MODE 3 conditions indefinitely with an inoperable CREF subsystem as long as the OPERABLE CREF subsystem is operating. With the system operating, automatic functions of the systems may not be required since the system is operating, however, there is a potential that an operating component can still fail if required (for example, power is not available). In MODE 3 conditions, the potential for a design basis accident still exists, therefore the allowance has been deleted since the failure of the operating subsystem may result in a failure to satisfy the requirements of the system. This change is designated as more restrictive since the option to start the OPERABLE CREF subsystem has been deleted. M.3 When both CREF subsystems are inoperable, CTS 3.17.B.1.b allows 24 hours to restore an inoperable CREF subsystem to OPERABLE status prior to initiating a reactor shutdown. When both CREF subsystems are inoperable due to an inoperable control room boundary, ITS 3.7.4 ACTION B allows 24 hours to restore the control room boundary to OPERABLE status. When both CREF subsystems are inoperable for reasons other than an inoperable control room boundary, ITS 3.7.4 ACTION E requires immediate entry into LCO 3.0.3. This will require the unit to initiate action within 1 hour to place the unit in MODE 2 within 7 hours, MODE 3 within 13 hours, and MODE 4 within 37 hours. This changes the CTS by requiring an immediate entry into LCO 3.0.3 when two Monticello Page 3 of 7 Attachment 1, Volume 12, Rev. 0, Page 70 of 161

Attachment 1, Volume 12, Rev. 0, Page 71 of 161 DISCUSSION OF CHANGES ITS 3.7.4, CONTROL ROOM EMERGENCY FILTRATION (CREF) SYSTEM CREF subsystems are inoperable for any reason other than the control room boundary being inoperable. The purpose of the CtS 3.17.B.1.b is to provide appropriate compensatory action when both CREF subsystems are inoperable. This change requires immediate entry into LCO 3.0.3 when two CREF subsystems are inoperable for any reason other than the control room boundary being inoperable. Under the same conditions in the CTS, 24 hours is allowed to restore one CREF subsystem prior to initiating a reactor shutdown. This change is acceptable because it does not allow the unit to operate for 24 hours with two inoperable CREF subsystems in MODES 1, 2, and 3. This is necessary because if there is an accident, the CREF subsystem will not be able to pressurize the control room boundary and ensure the control room dose remains within the safety analyses dose calculations. This change is designated as more restrictive because with two CREF subsystems inoperable in MODES 1, 2, and 3 the reactor will have to be shutdown sooner in the ITS than is currently allowed in the CTS. RELOCATED SPECIFICATIONS None -REMOVED DETAIL CHANGES LA.1 (Type 3 - Removing Procedural Details for Meeting TS Requirements or Reporting Requirements) CTS 4.17.B.1 states to "initiate from the control room" flow through CREF subsystem and operate for at least 10 hours. ITS SR 3.7.4.1 includes the same requirement, however, the statement to "initiate from the control room" is not included. This changes the CTS by moving the requirement to "initiate from the control room" from the CTS to the ITS Bases. The removal of these details for performing Surveillance Requirements from the Technical Specifications is acceptable because this type of information is not necessary to be included in the Technical Specifications to provide adequate protection of public health and safety. The ITS still retains the requirement to operate the CREF subsystem for > 10 hours in ITS SR 3.7.4.1. Also, this change is acceptable because these types of procedural details will be adequately controlled in the ITS Bases. Changes to the Bases are controlled by the Technical Specification Bases Control Program in Chapter 5. This program provides for the evaluation of changes to ensure the Bases are properly controlled. This change is designated as a less restrictive removal of detail change because procedural details for meeting Technical Specification requirements are being removed from the Technical Specifications. LA.2 (Type 1 - Removing Details of System Design and System Description, Including Design Limits) CTS 3.17.B.2.c.(3) and CTS 4.17.B.2.c.(3) require each CREF subsystem be shown to be OPERABLE with automatic initiation upon receipt of a "high radiation" signal. ITS SR 3.7.4.3 requires verification that each CREF subsystem actuates on an initiation signal. This changes the CTS by moving the specific type of actuation signal to the ITS Bases.

Attachment 1, Volume 12, Rev. 0, Page 72 of 161 DISCUSSION OF CHANGES ITS 3.7.4, CONTROL ROOM EMERGENCY FILTRATION (CREF) SYSTEM The removal'of these details, which are related to system design, from the Technical Specifications is acceptable because this type of information is not necessary to be included in the Technical Specifications to provide adequate protection of public health and safety. The ITS still retains the requirement to verify each CREF subsystem actuates on an initiation signal. Also, this change is acceptable because the removed information will be'adequately controlled in the ITS Bases. Changes to the Bases are controlled by the Technical Specification Bases Control Program in Chapter 5. This program provides for the evaluation of changes to ensure the Bases are properly controlled. This change is designated as a less restrictive removal of detail change because information relating to system design is being removed from the Technical Specifications. LESS RESTRICTIVE CHANGES L.i (Category 1 - Relaxation of LCO Requirement) CTS 3.17.B.1 requires two CREF subsystems to be OPERABLE, but does not allow the main control room boundary to be opened intermittently under administrative controls. If it is opened, both CREF subsystems are inoperable. ITS LCO 3.7.4 also requires the two CREF subsystems to be OPERABLE, however a Note to the LCO is included that allows the main control room boundary to be opened intermittently under administrative controls. This changes the CTS by allowing the main control room boundary to be opened intermittently under administrative controls and not consider the CREF System to be inoperable. The purpose of CTS 3.17.B.1 is to ensure the CREF System remains OPERABLE to support the safety analyses. This change is acceptable because the LCO requirements continue to ensure that the structures, systems, and components are maintained consistent with the safety analyses. The LCO is modified by a Note allowing the main control room boundary to be opened intermittently under administrative controls. The control room boundary is often opened intermittently to allow entry and exit and also periodically opened to perform maintenance. 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 consist of stationing a dedicated individual at the opening who is in continuous communication with the main control room. This individual will have a method to rapidly close the opening when a need for main control room isolation is indicated. This change is acceptable because the ITS Bases requires these administrative controls to be met in order to utilize the proposed LCO Note. This change is designated as less restrictive because less stringent LCO requirements are being applied in the ITS than were applied in the CTS. L.2 (Category6 - Relaxation Of Surveillance Requirement Acceptance Criteria) CTS 4.17.B.1 requires that each CREF subsystem be initiated with 1000 cfm (+/- 10%) of flow and operated for 10 hours. ITS SR 3.7.4.1 includes a similar requirement, except the flow rate is not specified. This changes the CTS by deleting the flow rate requirement from the Surveillance acceptance criteria. The purpose of 4.17.B.1 is to ensure the each CREF subsystem remains OPERABLE to support the safety analyses. This change is acceptable because it Monticello Page 5 of 7 Attachment 1, Volume 12, Rev. 0, Page 72 of 161

Attachment 1, Volume 12, Rev. 0, Page 73 of 161 DISCUSSION OF CHANGES ITS 3.7.4, CONTROL ROOM EMERGENCY FILTRATION (CREF) SYSTEM has been determined that the relaxed Surveillance Requirement acceptance criteria are not necessary for verification that the equipment used to meet the LCO can perform its required functions. This change deletes the flow rate requirement from the Surveillance acceptance criteria. Moisture may accumulate on the high efficiency particulate air filters and the charcoal adsorber when the system is in standby. Performing this Surveillance on a periodic frequency will remove the moisture since it is necessary for the heaters to actually operate (cycle properly when required) to reduce moisture from the adsorbers and HEPA filters. The actual flow rate is not specifically required to remove the moisture. Therefore, the explicit flow rate requirement has been deleted. Each CREF subsystem is still required to be tested at the specified flow rate as required by ITS SR 3.7.4.2 and ITS 5.5.6. This change is designated as less restrictive because less stringent Surveillance Requirements are being applied in the ITS than were applied in the CTS. L.3 (Category 6 - Relaxation Of Surveillance Requirement Acceptance Criteria) CTS 3.17.B.2.c.(3) and 4.17.B.2.c.(3) require verification of the automatic actuation of each CREF subsystem upon a receipt of the specified inputs (i.e., simulated signal). ITS SR 3.7.4.3 specifies that the signal may be from either an "actual" or "simulated" initiation signal. This changes the CTS by explicitly allowing the use of an actual signal for the test. The purpose of CTS 3.17.B.2.c.(3) and 4.17.B.2.c.(3) is to ensure that each CREF subsystem operates correctly upon receipt of an actuation signal. This change is acceptable because it has been determined that the relaxed Surveillance Requirement acceptance criteria are not necessary for verification that the equipment used to meet the LCO can perform its required functions. Equipment cannot discriminate between an "actual" or "simulated" signal and, therefore, the results of the testing are unaffected by the type of signal used to initiate the test. This change allows taking credit for unplanned actuation if sufficient information is collected to satisfy the Surveillance test requirements. The change also allows a simulated signal to be used, if necessary. This change is designated as less restrictive because less stringent Surveillance Requirements are being applied in the ITS than were applied in the CTS. L.4 (Category 7- Relaxation Of Surveillance Frequency, Non-24 Month Type Change) CTS 4.17.B.2.c.(3) requires each CREF subsystem to be operating in the pressurization mode of operation while maintaining the control room at a positive pressure with respect to adjacent areas, at least once per operating cycle. ITS SR 3.7.4.4 requires this same test, however it is required to be performed every 24 months "on a STAGGERED TEST BASIS." This changes the CTS by requiring the test to be performed using each CREF subsystem at least once per 48 months. The purpose of the CTS 4.17.B.2.c.(3), in part, is to ensure the integrity of the control room boundary. This change Is acceptable because the new Surveillance Frequency has been evaluated to ensure that it provides an acceptable level of equipment reliability. The change is acceptable since the proposed Surveillance Frequency will continue to require performance of the test every 24 months. This will ensure the control room boundary integrity is maintained. The status of the integrity of the control room boundary can be determined with either CREF Monticello Page 6 of 7 Attachment 1, Volume 12, Rev. 0, Page 73 of 161

Attachment 1, Volume 12, Rev. 0, Page 74 of 161 DISCUSSION OF CHANGES ITS 3.7.4, CONTROL ROOM EMERGENCY FILTRATION (CREF) SYSTEM subsystem. The secondary purpose of this test will now also serve to ensure that each CREF subsystem is being tested every 48 months (based on the definition of STAGGERED TEST BASIS). ITS SR 3.7.4.3 requires the performance of a test to ensure each CREF subsystem actuates on an actual or simulated initiation signal. Therefore, each subsystem will continue to be tested to ensure it can be automatically aligned to the pressurization mode, however the pressurization verification will only be required with one subsystem in operation. This change is designated as less restrictive because the pressurization Surveillance will only be required to be performed on one CREF subsystem each Surveillance interval instead of on both CREF subsystems. L.5 (Category 6 - Relaxation Of Surveillance Requirement Acceptance Criteria) CTS 4.17.B.2.c.(3) requires each CREF subsystem to be operating in the pressurization mode of operation while maintaining the control room at a positive pressure with respect to adjacent areas with a flow rate of 1000 cfm (+/- 10%). ITS SR 3.7.4.4 requires this same test, however the flow rate limit is specified to be < 1100 cfm. This changes the CTS by deleting the minimum flow rate limit. The purpose of the CTS 4.17.B.2.c.(3), in part, is to ensure the integrity of the control room boundary. This change is acceptable because it has been determined that the relaxed Surveillance Requirement acceptance criteria are not necessary for verification that the equipment used to meet the LCO can perform its required functions. The CREF flow rate limit range has been changed to a maximum flow rate limit. The CTS requires the CREF flow rate to be from 900 cfm to 1100 cfm during the control room boundary integrity test. In the ITS, the same test may be performed at < 1100 cfm. This change is acceptable because if the control room boundary is positive with a lower flow rate, the control room boundary is intact. This change is designated as less restrictive because less stringent Surveillance Requirements are being applied in the ITS than were applied in the CTS.

Actions must be taken to restore an OPERABLE main control room boundary within 24 hours. During the period that the main control room boundary is 10 CFR 50. inoperable, appropriate compensatory measures (consistent with the AnintoGDC 19) should be utilized to protect control room operators 0 from potential hazards such as radioactive contamination, toxic chemicals, smoke, temperature and relative humidity, and physical security. Preplanned measures should be available to address these concerns for intentional and unintentional entry into the condition. The 24 hour Completion Time is reasonable based on the low probability of a DBA occurring during this time period, and the use of compensatory measures. The 24 hour Completion Time is a typically reasonable time to diagnose, plan and possibly repair, and test most problems with the main control room boundary. C.i and C.2 In MODE 1, 2, or 3, if the inoperables ystem or control room ( boundary cannot be restored to OPERABLE status within the associated Completion Time, the unit must be placed in a MODE that minimizes risk. To achieve this status, the unit must be placed in at least MODE 3 within 12 hours and in MODE 4 within 36 hours. The allowed Completion Times are reasonable, based on operating experience, to reach the required unit conditions from full power conditions in an orderly manner and without challenging unit systems. D.1. D.2.11and 0.2.2 The Required Actions of Condition D are modified by a Note indicating that LCO 3.0.3 does not apply. If movingarecentlyi irradiated fuel ( 3 assemblies while in MODE 1, 2, or 3, the fuel movement is independent of reactor operations. Therefore, inability to suspend movement of mrecentlyM irradiated fuel assemblies is not sufficient reason to require a reactor shutdown.

Attachment 1, Volume 12, Rev. 0, Page 97 of 161 DISCUSSION OF CHANGES ITS 3.7.5, CONTROL ROOM VENTILATION SYSTEM ADMINISTRATIVE CHANGES A.1 In the conversion of the Monticello Current Technical Specifications (CTS) to the plant specific Improved Technical Specifications (ITS), certain changes (wording preferences, editorial changes, reformatting, revised numbering, etc.) are made to obtain consistency with NUREG-1433, Rev. 3, "Standard Technical Specifications General Electric Plants, BWR/4" (ISTS). These changes are designated as administrative changes and are acceptable because they do not result in technical changes to the CTS. A.2 Under certain conditions, CTS 3.17.A.2.c and CTS 3.17.A.3.c, in part, require immediate suspension of movement of irradiated fuel assemblies in the secondary containment. ITS 3.7.5 ACTIONS C and E include the same requirement, however a Note has been added that states that LCO 3.0.3 is not applicable. This changes the CTS by adding this Note. The purpose of CTS 3.17.A.2.a and CTS 3.17.A.3.c, in part, is to provide the appropriate actions when one or two control room ventilation subsystems, as applicable, are inoperable while moving irradiated fuel in the secondary containment. This change adds a Note that states LCO 3.0.3 is not applicable. This Note has been added because ITS LCO 3.0.3 has been added to ITS Section 3.0 in accordance with ITS Section 3.0 DOC M.1. This Note is necessary because if moving irradiated fuel assemblies while in MODE 4 or 5, LCO 3.0.3 would not specify any action. If moving irradiated fuel assemblies while in MODE 1, 2, or 3, the fuel movement Is independent of reactor operations. Therefore, in either case, inability to suspend movement of irradiated fuel assemblies would not be a sufficient reason to require a reactor shutdown. Since ITS LCO 3.0.3 is not currently included in the CTS this change is considered administrative. This change is designated as administrative because it does not result in technical changes to the CTS. A.3 These changes to CTS 3.17.A.1, CTS 3.17.A.2.c, and CTS 3.17.A.3.c are provided in the Monticello ITS consistent with the Technical Specifications Change Request submitted to the NRC for approval in NMC letter L-MT-04-023, from Thomas J. Palmisano (NMC) to USNRC, dated April 29, 2004. As such, these changes are administrative. MORE RESTRICTIVE CHANGES M.1 CTS 3.17.A.1 is applicable, in part, whenever irradiated fuel is in the reactor vessel and reactor water temperature is greater than 21 20 F. ITS LCO 3.7.5 is applicable in MODES 1, 2, and 3. This changes the CTS by requiring the Control Room Ventilation System to be OPERABLE in MODE 2 when reactor water temperature is less than or equal to 212 0F. The purpose of CTS 3.17.A.1 is to ensure the Control Room Ventilation System is OPERABLE to mitigate the consequences of a design basis accident. The Control Room Ventilation System is required to be OPERABLE during MODES 1, Monticello Page 1 of 3 Attachment 1, Volume 12, Rev. 0, Page 97 of 161

Attachment 1, Volume 12, Rev. 0, Page 98 of 161 DISCUSSION OF CHANGES ITS 3.7.5, CONTROL ROOM VENTILATION SYSTEM 2, and 3 when there is considerable energy in the reactor core or there is the potential for the reactor core to become critical and the Control Room Ventilation System would be required to mitigate the consequences of a design basis event. In MODES 1 and 3, the reactor coolant temperature will always be above 212 0 F. In MODE 2, the reactor coolant temperature may be less than or equal to 2120 F when the reactor Is subcritical but control rods are withdrawn. Therefore, it is necessary and acceptable to require the Control Room Ventilation System to be OPERABLE. This change is designated as more restrictive because the LCO will be applicable under more reactor operating conditions than in the CTS. M.2 CTS 4.17.A does not provide a requirement to verify the capability of the Control Room Ventilation System to remove the assumed heat load. ITS 3.7.5 includes a Surveillance Requirement to cover this requirement. ITS SR 3.7.5.1 requires verification that each control room ventilation subsystem has the capability to remove the assumed heat load every 24 months. This changes the CTS by adding an additional OPERABILITY requirement for the Control Room Ventilation System. The purpose of the new Surveillance Requirement is to ensure that the heat removal capability of the system is sufficient to remove the control room boundary heat load assumed in the safety analyses. The SR consists of a combination of testing and calculation. The 24 month Frequency is appropriate since significant degradation of the Control Room Ventilation System is not expected over this time period. This change is acceptable because it provides additional assurance that the Control Room Ventilation System will perform correctly during a design basis event. This change is designated as more restrictive because it adds a new Surveillance Requirement to the CTS. M.3 When both control room ventilation subsystems are inoperable, CTS 3.17.A.3.a allows 24 hours to restore an inoperable control room ventilation subsystem to OPERABLE status. If CTS 3.17.A.3.a is not met, CTS 3.17.A.3.b requires the unit to be in MODE 3 in 12 hours and in MODE 4 within the following 24 hours. ITS 3.7.5 ACTION D requires immediate entry into LCO 3.0.3 under the same conditions. This will require the unit to initiate action within 1 hour to place the unit in MODE 2 within 7 hours, MODE 3 within 13 hours, and MODE 4 within 37 hours. This changes the CTS by requiring an immediate entry into LCO 3.0.3 when two control room ventilation subsystems are inoperable. The purpose of the CTS 3.17.A.3.a and CTS 3.17.A.3.b is to provide appropriate compensatory actions when both control room ventilation subsystems are inoperable and place the unit in a MODE in which the LCO is no longer applicable in a reasonable amount of time if at least one subsystem is not restored to OPERABLE status. This change requires immediate entry into LCO 3.0.3 when two control room ventilation subsystems are inoperable. ITS 3.7.5 ACTION D does not include any specific time for restoration and requires immediate entry into LCO 3.0.3. This change is acceptable because the equipment in the control room boundary may not function correctly if a design basis event were to occur. This change places the unit outside of the applicability of the Specification where the system is not required to mitigate the consequences of those design basis events postulated during operating Monticello Page 2 of 3 Attachment 1, Volume 12, Rev. 0, Page 98 of 161

Attachment 1, Volume 12, Rev. 0, Page 99 of 161 DISCUSSION OF CHANGES ITS 3.7.5, CONTROL ROOM VENTILATION SYSTEM conditions. This change is designated as more restrictive since the restoration time of 24 hours has been deleted. RELOCATED SPECIFICATIONS None REMOVED DETAIL CHANGES None LESS RESTRICTIVE CHANGES L.1 (Category 5- Deletion of Surveillance Requirement) CTS 4.17.A.1 requires verification that the control room temperature is within limit. ITS 3.7.5 does not include this requirement. This changes the CTS by eliminating the Surveillance Requirement to verify control room temperature. The purpose of CTS 4.17.A.1 is to ensure the continuous duty rating for the instrumentation and equipment cooled by this system is not exceeded. This change is acceptable because the deleted Surveillance Requirement is not necessary to ensure the Control Room Ventilation System can perform its safety function. ITS SR 3.7.5.1 has been added in accordance with DOC M.2 to verify each control room ventilation subsystem has the capability to remove the assumed heat load. This SR will ensure the Control Room Ventilation System can perform its safety function. Temperature is not always the appropriate method to verify the system capability to remove its design basis heat load because the conditions in the control room boundary do not always reflect the assumptions of the accident (e.g., personnel assumed to be in the control room boundary during an accident, the system does not normally operate in the pressurization mode of operation). ITS SR 3.7.5.1 will ensure each control room ventilation subsystem has sufficient cooling capability to meet the safety analyses assumptions. This change is designated as less restrictive because a Surveillance that is required in the CTS will not be required in the ITS.

Total system failure could result in the equipment operating temperature exceeding limits.

TheRControl Room&System is considered OPERABLE when the (i) individual components necessary to maintain the control roomybudr temperature are OPERABLE in both subsystems. These components include the cooling coils, fans, c rs compressors, ductwork, dampers, and associated instrumentation and controls. Ventilabon APPLICABILITY In MODE 1,2, or 3, thelControl RoomE&System must be OPERABLE to ensure that the 'control roomrtemperature will not exceed equipment i) 0 lbounda OPERABILITY limits following control room isolation. In MODES 4 and 5, the probability and consequences of a Design Basis Accident are reduced due to the pressure and temperature limitations in these MODES. Therefore, maintaining the lControl Room stm OPERABLE is not required in MODE 4 or 5, except for the following n; 0i bd situations under wich significant radioactive releases can be postulated:

a. During operations with a potential for draining the reactor vessel (OPDRVs),and f
b. During movement of irradiated fuel assemblies in the Irentl secondarA containment. [Due to rdioactive decay, the Co ol oom ys em is only require to be OPERABLE duri fuel han ng involving handling re ntly irradiated fuel (i.e. el that has 0

However, the overall reliability is reduced because a single failure in the OPERABLE subsystem could result in loss of the control roornair conditioning function. The 30 day Completion Time is e low probability of an event occurring requiring control room isolation, the consideration that the remaining subsystem can provide the required protection, and the availability of alternate safety and nonsafety cooling methods.

To achieve this status, the unit must be placed in at least MODE 3 within 12 hours and in MODE 4 within 36 hours. The allowed Completion Times are reasonable, based on operating experience, to reach the required unit conditions from full power conditions in an orderly manner and without challenging unit systems. C.1. C.2.1. and C.2.2 The Required Actions of Condition C are modified by a Note indicating that LCO 3.0.3 does not apply. If moving [re ntly irradiated fuel (i) assemblies while in MODE 1, 2, or 3, the fuel movement is independent of reactor operations. Therefore, inability to suspend movement of [recntly irradiated fuel assemblies is not sufficient reason to require a (i reactor shutdown. During movement of re ntl irradiated fuel assemblies in the Osecondari, containment or during OPDRVs, if Required Action A.1

          ~o         ant ecmlted within the required Completion Time, the OPERABLE I~control room'M subsystem may be placed immediately in Operation. This action ensures that the remaining subsystem is OPERABLE, that no failures that would prevent actuation will occur, and that any active failure will be readily detected.

An alternative to Required Action C.1 is to immediately suspend activities that present a potential for releasing radioactivity that might require isolation of the control room. This places the unit in a condition that minimizes risk. If applicable, movement o [re ntl irradiated fuel assemblies in the 14Th TsecondaryM containment must be suspended immediately. Suspension o these activities shall not preclude completion of movement of a component to a safe position. Also, if applicable, actions must be initiated immediately to suspend OPDRVs to minimize the probability of a vessel draindown and subsequent potential for fission product release. Actions must continue until the OPDRVs are suspended. BWR/4 STS B 3.7.5-3 Rev. 3.0, 03/31/04 Attachment 1, Volume 12, Rev. 0, Page 108 of 161

D.1 If both gcontrol room subsystems are inoperable in MODE 1, 2, or 3,1 the mControl Room gystem may not be capable of performing the intended function. Therefore, LCO 3.0.3 must be entered immediately. E.1 and E.2 The Required Actions of Condition E are modified by a Note indicating that LCO 3.0.3 does not apply. If moving [repcintly irradiated fuel assemblies while in MODE 1, 2, or 3, the fuel movement is independent of reactor operations. Therefore, inability to suspend movement of [recently irradiated fuel assemblies is not a sufficient reason to require a reactor shutdown. I ebabonl During movement of [re htly] irradiated fuel assemblies in the V(1 lsecondar containmentor uring OPDRVs, with two control roomin subsystems inoperable, action must be taken immediately to suspend activities that present a potential for releasing radioactivity that might require isolation of the control room. This places the unit in a condition that minimizes risk. If applicable, handling offjic~tly irradiated fuel in the Isecondary( containment must be suspended immediately. Suspension of these activities shall not preclude completion of movement of a component to a safe position.

Attachment 1, Volume 12, Rev. 0, Page 117 of 161 DISCUSSION OF CHANGES ITS 3.7.6, MAIN CONDENSER OFFGAS ADMINISTRATIVE CHANGES A.1 In the conversion of the Monticello Current Technical Specifications (CTS) to the plant specific Improved Technical Specifications (ITS), certain changes (wording preferences, editorial changes, reformatting, revised numbering, etc.) are made to obtain consistency with NUREG-1433, Rev. 3, "Standard Technical Specifications General Electric Plants, BWR/4" (ISTS). These changes are designated as administrative changes and are acceptable because they do not result in technical changes to the CTS. A.2 CTS 3.8.A.1 requires the main condenser offgas activity to be within limit "Whenever the Steam Jet Air Ejectors (SJAEs) are in operation." CTS 4.8.A requires the main condenser offgas activity Surveillance to be performed "after the SJAEs are in operation." ITS LCO 3.7.6 also requires the main condenser offgas activity to be within limit, however the Applicability is MODE 1, and MODES 2 and 3 with any main steam line not isolated and steam jet air ejector (SJAE) in operation. ITS SR 3.7.6.1 includes the same Surveillance requirement to verify the main condenser offgas activity, however a Note has been included that requires the Surveillance to be performed "after any main steam line is not isolated and SJAE in operation." This changes the CTS by clarifying that the LCO is always applicable in MODE 1, and only in MODES 2 and 3 when any main steam line is opened and a SJAE is in operation, and also allows the Surveillance to be performed only after both a main steam line is opened and a SJAE is in service. The purpose of CTS 3.8.A.1, in part, is to state when the main condenser offgas activity is applicable. The purpose of CTS 4.8.A, in part, is to state when the Surveillance is required to be performed. This change clarifies that the LCO is always applicable in MODE 1, and only in MODES 2 and 3 when any main steam line is opened and a SJAE is in operation, and also allows the Surveillance to be performed only after both a main steam line is opened and a SJAE is in service. The SJAEs cannot be placed in service without main steam pressure (i.e., any main steam line not isolated). This proposed Applicability is consistent with the CTS 3.8.A.3 default action to isolate the main steam lines, isolate the SJAEs, or be in cold shutdown. The Surveillance will be required to be performed at the same time as in the CTS since the SJAE cannot be placed in service without steam line pressure. This change is also acceptable because it matches the Actions and Applicability. In addition, the main condenser offgas activity limit is only necessary when the main steam is directed to the main condenser and the offgas system is in operation since this iswhen there is a potential for the Main Condenser Offgas System to rupture. This change is designated as administrative because it does not result in technical changes to the CTS.

Attachment 1, Volume 12, Rev. 0, Page 124 of 161 Main Condenser Offgas B 3.7.6 B 3.7 PLANT SYSTEMS B 3.7.6 Main Condenser Offgas BASES BACKGROUND During unit operation, steam from the low pressure turbine is exhausted directly into the condenser. Air and noncondensible gases are collected in the condenser, then exhausted through the steam jet air ejectors (SJAEs) to the Main Condenser Offgas System. The offgas from the main condenser normally includes radioactive gases. The Main Condenser Offgas System has been incorporated into the unit design to reduce the gaseous radwaste emission. This system uses a catalytic recombiner to recombine radiolytically dissociated hydrogen and oxygen. The gaseous mixture is cooled by the offgas condenser; the water and condensibles are stripped out by the offgas condenser a d moistu epara o.

APPLICABILITY The LCO is applicable when steam is being exhausted to the main condenser and the resulting noncondensibles are being processed via the Main Condenser Offgas System. This occurs during MODE 1, and during MODES 2 and 3 with any main steam line not isolated and] the SJAE in operation. In MODES 4 and 5, steam is not being exhausted to the main 0D condenser and the requirements are not applicable.

Attachment 1, Volume 12, Rev. 0, Page 126 of 161 Main Condenser Offgas B 3.7.6 BASES ACTIONS A.1 If the offgas radioactivity rate limit is exceeded, 72 hours is allowed to restore the gross gamma activity rate to within the limit. The 72 hour Completion Time is reasonable, based on engineering judgment, the time required to complete the Required Action, the large margins associated with permissible dose and exposure limits, and the low probability of IMa in Conde nse fasSystiem rup . NsERT3 B.1, B.2, B.3.1. and B.3.2 If the gross gamma activity rate is not restored to within the limits in the associated Completion Time,fNall main steam lines orl the SJAE must be isolated. This isolates the Main Condenser Offgas System from the source of the radioactive steam. The main steam lines are considered isolated if at least one main steam isolation valve in each main steam line is closed, and at least one main steam line drain valve in each drain line is closed. The 12 hour Completion Time is reasonable, based on operating experience, to perform the actions from full power conditions in an orderly manner and without challenging unit systems. An altemative to Required Actions B.1 and B.2 is to place the unit in a MODE in which the LCO does not apply. To achieve this status, the unit must be placed in at least MODE 3 within 12 hours and in MODE 4 within 36 hours. The allowed Completion Times are reasonable, based on operating experience, to reach the required unit conditions from full power conditions in an orderly manner and without challenging unit systems. SURVEILLANCE SR 3.7.6.1 REQUIREMENTS This SR, on a 31 day Frequency, requires an isotopic analysis of an offgas sample to ensure that the required limits are satisfied. The noble gases to be sampled are Xe-1 33, Xe-1 35, Xe-1 38, Kr-85, Kr-87, and Kr-88. If the measured rate of radioactivity increases significantly (by 2 50% after correcting for expected increases due to changes in THERMAL POWER), an isotopic analysis is also performed within 4 hours after the increase is noted, to ensure that the increase is not indicative of a sustained increase in the radioactivity rate. The 31 day Frequency is adequate in view of other instrumentation that continuously monitor the offgas, and is acceptable, based on operating experience. This SR is modified by a Note indicating that the SR is not required to be performed until 31 days after anyljmain steam line is not isolated andc the 0 SJAE is in operation. Only in this condition can radioactive fission gases be in the Main Condenser Offgas System at significant rates.

ITS LCO 3.7.7 requires the Main Turbine Bypass System to be OPERABLE. This changes the CTS by incorporating the requirements of ITS 3.7.7. Appropriate ACTIONS and Surveillance Requirements are also provided. The Monticello transient analyses credit the opening of the turbine bypass valves during certain events. If the Main Turbine Bypass System is inoperable, the safety analyses are not met. This change is acceptable since the Monticello transient analyses credit the Main Turbine Bypass System; therefore, the LCO ensures that the assumptions of the safety analyses are conserved. This change is designated as more restrictive because it adds new requirements to the CTS.

Attachment 1, Volume 12, Rev. 0, Page 141 of 161 Main Turbine Bypass System B 3.7.7 B 3.7 PLANT SYSTEMS B 3.7.7 Main Turbine Bypass System BASES BACKGROUND The Main Turbine Bypass System is designed to control steam pressure when reactor steam generation exceeds turbine requirements during unit startup, sudden load reduction, and cooldown. It allows excess steam r flow from the reactor to the condenser without going through the turbine. a The bypass capacity of the system is% of the Nuclear Steam Supply A) System rated steam flow. Sudden load reductions within the capacity of the steam bypass can be accommodated without reactor scram. The Main Turbine Bypass System consists t e valves connected to the Q m steam lines between the main steam isolation valves and the turbine

     'Electrical Pressure        stop valve bypass valve chest. Each of th se re valves is operated by Mechanical Pressure        hydraulic cylinders. The bypass valves are controlled by the pressure Regulator                  regulation function of the Turbine6lectro Hydrauliontrol Systen , as discussed in th SAR, Sec7ioQ [7 .4] (Ref. 1). The bypass valves are ii.norm-a y cosed, and the pressure regulator controls the turbine control valves that direct all steam flow to the turbine. If the speed governor or the load limiter restricts steam flow to the turbine, the pressure regulator controls the system pressure by opening the bypass valves. When the bypass valves open, the steam flows from the bypass chest, through connecting piping, to the pressurelbreakdowrl assemblies, where s ie lof orifices are          urther reduce the steam pressure before the steam enters the condenser.                        isreduced APPLICABLE                     E  The Main Turbine Bypass System is assumed to function during the SAFETY                             turbine eereoad          reiection transient as discussed in thefgAR, ANALYSES                           Section [15.1. e. 2 Opening the bypass valves during the eedwaterontrlerven                                     mitigates the      ase in reactor vessel pr failure (maximum                 which affects the MCPR during the event. n opdrable Mainur                        /

Attachment 1, Volume 12, Rev. 0, Page 151 of 161 v>DISCUSSION OF CHANGES. ITS 3.7.8, SPENT FUEL STORAGE POOL WATER LEVEL ADMINISTRATIVE CHANGES A.1 In the conversion of the Monticello Current Technical Specifications (CTS) to the plant specific Improved Technical Specifications (ITS), certain changes (wording preferences, editorial changes, reformatting, revised numbering, etc.) are made to obtain consistency with NUREG-1433, Rev. 3, "Standard Technical Specifications General Electric Plants, BWR/4" (ISTS). These changes are designated as administrative changes and are acceptable because they do not result in technical changes to the CTS. A.2 These changes to CTS 3.10.C and CTS 4.10.C are provided in the Monticello ITS consistent with the Technical Specifications Change Request submitted to the USNRC for approval in NMC letter L-MT-05-013, from Thomas J. Palmisano (NMC) to USNRC, dated April 12, 2005. As such, these changes are administrative. A.3 Under certain conditions, CTS 3.10.C, in part, requires immediate suspension of movement of irradiated fuel assemblies. ITS 3.7.8 ACTION A includes the same requirement, however a Note has been added that states that LCO 3.0.3 is not applicable. This changes the CTS by adding this Note. The purpose of CTS 3.10.C, in part, is to provide the appropriate actions when the spent fuel storage pool water level is not within limit. This change adds a Note that states LCO 3.0.3 is not applicable. This Note has been added because ITS LCO 3.0.3 has been added to ITS Section 3.0 in accordance with ITS Section 3.0 DOC M.1. This Note is necessary because if moving irradiated fuel assemblies while in MODE 4 or 5, ITS LCO 3.0.3 would not specify any action. If moving irradiated fuel assemblies while in MODE 1, 2, or 3, the fuel movement is independent of reactor operations. Therefore, in either case, inability to suspend movement of irradiated fuel assemblies would not be a sufficient reason to require a reactor shutdown. Since ITS LCO 3.0.3 is not currently included in the CTS, this change is considered administrative. This change is designated as administrative because it does not result in any technical changes to the CTS. A.4 CTS 4.10.C.2 requires verification that the spent fuel storage pool water level is within limit once every 7 days when irradiated fuel assemblies are stored in the spent fuel storage pool. This Surveillance is not included in ITS 3.7.8. This changes the CTS by deleting this Surveillance. The purpose of CTS 4.10.C.2 is to ensure there is sufficient water in the spent fuel storage pool when irradiated fuel assemblies are stored in the spent fuel storage pool. The applicability specified in CTS 3.10.C is "during movement of irradiated fuel assemblies," not "when irradiated fuel assemblies are stored in the spent fuel storage pool." CTS 4.10.C.1 requires verification that the spent fuel storage pool water level is within limit once every 24 hours during movement of irradiated fuel assemblies. CTS 4.0.C states that whenever the plant condition is such that a system or component is not required to be OPERABLE, the Surveillance testing associated with that system or component may be discontinued. This allowance is retained in SR 3.0.1. Therefore, CTS 4.1 0.C.2 is not required to be met or performed. The requirements in CTS 3/4.1 0.C have Monticello Page 1 of 2 Attachment 1, Volume 12, Rev. 0, Page 151 of 161

Attachment 1, Volume 12, Rev. 0, Page 152 of 161

                           - DISCUSSION OF CHANGES ITS 3.7.8, SPENT FUEL STORAGE POOL WATER LEVEL recently been proposed to be modified (as discussed in DOC A.2) to ensure that when irradiated fuel assemblies are being moved over the spent fuel storage pool, the spent fuel storage pool level is adequate to ensure the consequences of fuel handling accident over the spent fuel pool will be bounded by the safety analysis. This specific Surveillance should not have been added to the Technical Specifications as part of this Amendment request. Therefore, this Surveillance is not required and is deleted. This change is designated as administrative because it does not result in technical changes to the CTS.

MORE RESTRICTIVE CHANGES None RELOCATED SPECIFICATIONS None REMOVED DETAIL CHANGES None LESS RESTRICTIVE CHANGES L.1 (Category 7 - Relaxation of Surveillance Frequency, Non-24 Month Type Change) CTS 4.1 O.C.1 requires a verification every 24 hours that the spent fuel storage pool water level is within the limit. ITS SR 3.7.8.1 requires verifying the spent fuel storage pool water level is within the limit every 7 days. This changes the CTS by extending the Surveillance Frequency from 24 hours to 7 days. The purpose of CTS 4.1 O.C.1 is to ensure the spent fuel storage pool water level is within limit. This change extends the Surveillance Frequency from 24 hours to 7 days. This change is acceptable because the new Surveillance Frequency has been evaluated to ensure that it provides an acceptable level of reliability. The change in Surveillance Frequency from 24 hours to 7 days maintains a Frequency that is adequate to trend changes in the spent fuel storage pool water level. In addition, a control room alarm exists to alert the operator to a decreasing water level. This change is designated as less restrictive because Surveillances will be performed less frequently under the ITS than under the CTS.

1. The brackets have been removed and the proper plant specific information/value has been provided.
2. ISTS LCO 3.7.8 requires the spent fuel storage water level to be 23 ft over the top of irradiated fuel assemblies seated in the spent fuel storage pool racks and ISTS SR 3.7.8.1 requires verification that the spent fuel storage water level to be 23 ft over the top of irradiated fuel assemblies seated in the spent fuel storage pool racks. The.

value of 23 ft is bracketed. ITS LCO 3.7.8 requires the spent fuel storage water level to be > 37 ft above the bottom of the spent fuel storage pool and ITS SR 3.7.8.1 requires verification that the spent fuel storage level is > 37 ft above the bottom of the spent fuel storage pool. The proposed level will ensure there is > 21 ft 4 inches of water over the top of irradiated fuel assemblies seated in the spent storage pool racks. The proposed level is acceptable because the safety analyses shows that the radiological consequences of a refueling accident occurring over the core bounds the same accident over the spent fuel storage pool. The value and method of referencing the spent fuel storage pool level in ITS LCO 3.7.8 and ITS SR 3.7.8.1 is consistent with a recent NMC License Amendment Request, as provided in NMC letter L-MT-05-013, from Thomas J. Palisano (NMC) to USNRC, dated April 12, 2005. Monticello Page 1 of 1 Attachment 1, Volume 12, Rev. 0, Page 155 of 161

The fuel handling accident is evaluated for the dropping of an irradiated fuel assembly onto the reactor core. The consequences of a fuel handling accident over the spent fuel storage pool are no more severe m than those of the fuel handling accident over the reactor core, ask 43 discussed in the SAR, Sectio (9.1 .2.2] (Ref.l.-The water leveTn the(D i) spent fuel storage pool provides for absorption of water soluble fission product gases and transport delays of soluble and insoluble gases that must pass through the water before being released to the secondary containment atmosphere. This absorption and transport delay reduces the potential radioactivity of the release during a fuel handling accident. The spent fuel storage pool water level satisfies Criteria 2 and 3 of 10 CFR 50.36(c)(2)(ii). LCO The specified water level preserves the assumptions of the fuel handling accident analysis (Ref. 2). As such, it is the minimum required for fuel movement within the spent fuel storage pool. APPLICABILITY This LCO applies during movement of irradiated fuel assemblies in the spent fuel storage pool since the potential for a release of fission products exists.

Attachment 1, Volume 12, Rev. 0, Page 158 of 161 Spent Fuel Storage Pool Water Level B 3.7.8 BASES ACTIONS A.1 Required Action A.1 is modified by a Note indicating that LCO 3.0.3 does not apply. If moving irradiated fuel assemblies while in MODE 1, 2, or 3, the fuel movement is independent of reactor operations. Therefore, inability to suspend movement of irradiated fuel assemblies is not a sufficient reason to require a reactor shutdown. When the initial conditions for an accident cannot be met, action must be taken to preclude the accident from occurring. If the spent fuel storage pool level is less than required, the movement of irradiated fuel assemblies in the spent fuel storage pool is suspended immediately. Suspension of this activity shall not preclude completion of movement of an irradiated fuel assembly to a safe position. This effectively precludes a spent fuel handling accident from occurring. SURVEILLANCE SR 3.7.8.1 REQUIREMENTS This SR verifies that sufficient water is available in the event of a fuel handling accident. The water level in the spent fuel storage pool must be checked periodically. The 7 day Frequency is acceptable, based on operating experience, considering that the water volume in the pool is normally stable, and all water level changes are controlled by unit procedures.
