Part D Package 3.7 NSHD Change category number Discussion Of Change 3.7 A

002 CTS 3.4.A, 3.4.B, 3.4.C, 3.4.D, 3.3.C, 3.3.D, 3.6.E and 3.6.F.

The CTS contain prose descriptions of the conditions for which the specification is applicable. This description has been replaced with the equivalent MODES of applicability for the ITS. Since the plant conditions to which this specification apply have not changed, this is an administrative change.

L 003 CTS 3.4.A.2.a. A new Condition and associated Required Action and Completion Time are included to allow 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> to restore the inoperable MSSV to operable status or begin preparations to shut the plant down. PI CTS does not address the condition when a MSSV is inoperable. The 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> Completion Time is reasonable to assess the inoperability and perform minor repairs. The probability of an event or transient occurring during this 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> period which requires any given MSSV to be operable is extremely low. In the remote case an event did occur during this time the plant would rely upon other systems (i.e. PORVs) to shut the plant down in a safe manner.

PI is not proposing to continue plant operation for extended periods at reduced power with less than all ten MSSVs operable; therefore an allowed outage time is required to restore an inoperable valve and make preparations to shut down. This change is less restrictive since CTS would require entry into CTS 3.0.C which would allow the plant to continue to operate 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> while corrective actions are pursued.

Package 3.7 Discussion Of Change NSHD category L

Prairie Island Units 1 and 2 2/2/02 Part D 007 CTS 3.4.A.2.a. This change will allow one SG PORV to be inoperable for 7 days and two SG PORVs inoperable for I hour. It is acceptable to have one SG PORV inoperable for this length of time because the other SG PORV is still operable and there are other comparable means of heat removal such as the Steam Dump and Main Steam Safety Valves. It is acceptable to have two SG PORVs inoperable for 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> because there is a low probability of a SG Tube Rupture coincident with a loss of offsite power. Also there are other means of removing heat such as the Steam Dump and Main Steam Safety Valves. Since these changes extend the time the plant can operate with equipment out of service, these changes are less restrictive.

Change number 3.7-4

Part D Package 3.7 NSHD Change category number Discussion Of Change 3.7 M

008 CTS 3.4.B.1.a and 3.4.B.2. In conformance with the guidance of NUREG-1431, the more general term "train" is used instead of only requiring AFW pumps to be operable.

Since the requirement for a "train" to be operable may require more equipment, this change is more restrictive.

Also the specifications have been simplified in that the AFW requirements for a single unit operating are specified. If two units are operating, then the same requirements apply to each unit individually. CTS 3.4.B.2 also contained a statement that if the OPERABILITY of the AFW pump is not restored to OPERABILITY within the specified time, place the affected unit (or either unit in the case of the motor driven AFW pump inoperability) or initiate a shutdown track.

PI design is that a motor driven AFW pump can be cross tied and aligned to provide feedwater to the SGs to the other unit. In this case, one unit must be in a shutdown condition and the other unit motor driven AFW pump inoperable. PI is deleting this CTS flexibility and therefore, making this a more restrictive change. Eliminating this flexibility is acceptable since the ITS provides specific Conditions and Required Actions for individual unit equipment inoperabilities.

009 CTS 3.4.B.1.b. The AFW requirements for two units operating have been included in the ITS LCO such that the requirements are the same for each operating unit; thus a separate statement for two unit operation is not required. Since these requirements have been incorporated into the ITS, this is an administrative change.

010 Not used.

Part D Package 3.7 NSHD Change category number Discussion Of Change 3.7 L

011 CTS 3.4.B.1.c. This statement has been replaced with a LCO Note which specifies that AFW is considered operable during alignment and operation for SG level control if capable of being manually realigned to the AFW mode of operation. Since the note is broader in scope than this specification, this change is considered less restrictive. This change incorporates the conditions of NRC letter from Beth Wetzel to Roger Anderson, dated October 17, 1997.

M 012 A new SR, 3.7.5.1, is included which requires that AFW valves that are not locked, sealed or otherwise secured in position, are in the correct position. Since this SR requires additional plant activities, it is more restrictive. This more restrictive change is included to make the PI ITS complete. This change is consistent with the guidance of NUREG-1431.

M 013 A new specification, 3.7.2, is included which requires two MSIVs to be operable. PI CTS require surveillance of the MSIVs but does not include any limiting conditions for operations. Since this new specification places additional restrictions on the plant, this change is more restrictive. This change is included to make the P1 ITS consistent with the guidance of NUREG-1431. This change is acceptable because the MSIVs are currently administratively required to be operable by the plant.

Part D Package 3.7 NSHD Change category number Discussion Of Change 3.7 M

014 A new specification, 3.7.3, is included which requires two MFRVs and associated bypass valves to be operable. Since this new specification places additional restrictions on the plant, this change is more restrictive. This change is included to make the PI ITS consistent with the guidance of NUREG-1431. This change is acceptable because the MFRVs and associated bypass valves are currently administratively required to be operable by the plant.

M 015 Two new SRs, 3.7.3.1 and 3.7.3.2 are included which require verification of the isolation time for the MFRV and MFRV bypass valves on an actual or simulated signal. Since these new specifications place additional restrictions on the plant, these changes are more restrictive. These changes are included to make the PI ITS consistent with the guidance of NUREG-1431. These changes are acceptable because the MFRVs and MFRV bypass valves are currently administratively required to be operable by the plant.

M 016 CTS 3.4.B.1.d. The CTS requirement for 100,000 gallons of water in the CTSs is clarified to require 100,000 gallons per unit. Since this requires more water than is currently required, this is a more restrictive requirement. This change is acceptable because the plant currently maintain 100,000 gallons per unit in accordance with current plant procedures.

PartD Package 3.7 Discussion Of Change NSHD category LR LR Prairie Island Units 1 and 2 12/11/00 Change number 3.7-017 CTS 3.4.B.1.d. The details of the OPERABILITY requirements for the condensate storage tank, including backup water supply requirements have been relocated to the Bases. These specification details are unnecessary since the Specification requirement that the CST is OPERABLE envelopes these requirements. This change is consistent with the guidance of NUREG-1431. Since the ITS Bases (under the Bases Control Program in Section 5.5 of the ITS) are licensee controlled, this change is less restrictive.

018 CTS 3.4.B.1.e, f and g. The details of the OPERABILITY requirements for AFW system motor operated and manual valves, and condensate cross connect valve to the AFW system have been relocated to the TRM. These specification details are unnecessary in the TS since the Specification requirement that the AFW system is OPERABLE envelopes these requirements. This change is consistent with the guidance of NUREG-1431. Since the TRM is licensee controlled, this change is less restrictive. This change is acceptable since the TRM is under the regulatory controls of 10 CFR 50.59.

Package 3.7 Part D 8

NSHD Change category number Discussion Of Change 3.7 LR 019 CTS 3.4.B.2.a. CTS and ITS allow startup to proceed without demonstration of AFW pump and associated valve operability.

CTS details on the conditions of inoperability have been relocated to the Bases. This change is consistent with the guidance of NUREG-1431 as modified by approved travellers.

This change is acceptable because the turbine driven AFW pumps will continue to be maintained and tested as they are under the CTS requirements. Since the ITS Bases (under the Bases Control Program in Section 5.5 of the ITS) are licensee controlled, this change is less restrictive.

A 020 CTS 3.4.B.2. CTS states that. "any one of the following conditions of inoperability may exist..." This requirement prevents two or more of the listed conditions from existing at the same time. The limitation that only one condition of inoperability may exist is not explicitly stated in ITS. In ITS, these conditions may be in more than one specification.

However, in the NUREG-1431 format, the SFDP exists to provide a mechanism to assure that entry into multiple TS Conditions will not result in loss of safety function. Thus the SFDP limits these conditions from simultaneous existence when there is a loss of safety function. The Maintenance Rule will also assure that multiple equipment inoperabilities are evaluated for reduction of plant safety. Since the ITS includes provisions to address this clause, there is no net change in plant safety and this is an administrative change.

Part D Package 3.7 NSHD Change category number Discussion Of Change 3.7 A

021 CTS 3.4.B.2.a. The CTS requirements for completion of turbine driven AFW pump testing have been reworded to be consistent with the NUREG-1431 format. Since there are no substantive changes, this is an administrative change.

L 022 CTS 3.4.B.2. A new Condition is included which allows one steam supply to the turbine driven AFW pump to be inoperable for 7 days and 10 days from discovery of failure to meet the LCO. This is less restrictive since the CTS allow a TDAFW pump, valve or piping to be inoperable for 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. However, the TDAFW pump is NOT inoperable when one steam supply is inoperable. Seven days and 10 days from discovery of failure to meet the LCO are acceptable since there is a redundant steam supply to the pump; there is also a redundant motor driven pump and there is a low probability of an event which requires the inoperable steam supply to the TDAFW pump. This change is consistent with the guidance of NUREG-1431.

M 023 CTS 3.4.B.2.a. The CTS requirement that specifies equipment that may be inoperable is generalized to allow an AFW train to be inoperable. Since more equipment under this specification may make the AFW train inoperable, this change is considered more restrictive. Since a "train" of equipment is more inclusive, this change may enhance plant safety. This change is consistent with the guidance of NUREG-1431.

Prairie Island Units 1 and 2 10 2/2/02

Part D Package 3.7 NSHD Change category number Discussion Of Change 3.7 LR 024 CTS 3.4 B.2.b. Since the ITS specifies that a whole train may be inoperable, the definition of equipment that may be inoperable is unnecessary in the TS and therefore relocated to the Bases. This change is consistent with the guidance of NUREG-1431. Since the ITS Bases (under the Bases Control Program in Section 5.5 of the ITS) are licensee controlled, this change is less restrictive.

L 025 CTS 3.4.B.2.c. This change will allow the CSTs to be inoperable for 7 days. This is acceptable due to the availability of the backup supply of water from the cooling water system and the low probability of an event during this time which will require the CSTs. Also, inoperable CSTs does not necessarily mean total loss of function, such as the circumstances when the CST level is low. This change is consistent with the guidance of NUREG-1431. Since plant equipment may be inoperable for additional time beyond that allowed in the CTS, this change is less restrictive.

M 026 CTS 3.4.B.2.c. The ITS requires verification of cooling water supply availability within four hours and every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> thereafter. This additional verification provides that the plant will be maintained in a safe condition during the extended time the CSTs are allowed to be inoperable. Since a specific time for verification is provided, this is a more restrictive change.

Verification within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> and every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> thereafter does not place the plant at risk and may improve plant safety. This change is consistent with the guidance of NUREG-1431.

Prairie Island Units 1 and 2 11 12/11/00

Package 3.7 Discussion Of Change NSHD category M

LR Prairie Island Units 1 and 2 12/11/00 Part D Change number 3.7-027 A new SR, 3.7.6.1, is included which requires verification of the CST inventory every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. Currently plant procedures require verification of CST inventory; however, since this SR makes this verification a TS requirement, this change is considered more restrictive. This more restrictive change is included to make the PI ITS complete. This change is consistent with the guidance of NUREG-1431.

028 CTS 3.4.B.2.d. The details of inoperability conditions for the AFW backup supply of water from the cooling water system have been relocated to the Bases for the AFW system. AFW system OPERABILITY will require the availability of the backup water supply. Therefore, these specification details are unnecessary since the Specification requirement for AFW system OPERABILITY and associated ACTIONS envelope these requirements. This change is consistent with the guidance of NUREG-1431. Since the ITS Bases (under the Bases Control Program in Section 5.5 of the ITS) are licensee controlled, this change is less restrictive.

12

NSHD Change category number Discussion Of Change 3.7 LR 029 CTS 3.4.B.2.e. The details of inoperability conditions for AFW system valves have been relocated to the TRM. These specification details are unnecessary since the Specification requirement for AFW system OPERABILITY and associated ACTIONS envelopes these requirements. This change is consistent with the guidance of NUREG-1431. Since the TRM is licensee controlled, this change is less restrictive.

This change is acceptable since the TRM is under the regulatory controls of 10 CFR 50.59.

This CTS requirement does not meet 10CFR50.36(c )(2)(ii) criteria for inclusion into the ITS as follows:

Criterion 1: Installed instrumentation that is used to detect and indicate in the control room, a significant abnormal degradation of the reactor coolant pressure boundary.

This Specification only applies to valve position lights for AFW system motor operated valves MV32242 and MV32243 (unit 2 MV32248 and MV32249). These lights show AFW valve position and do not provide any function for detection of an abnormal degradation of the reactor coolant system.

Therefore, they do not meet criteria 1.

Criterion 2: A process variable, design feature, or operating restriction that is an initial condition of a design basis accident or transient analysis that either assumes the failure of or presents a challenge to the integrity of a fission barrier:

This Specification only provides valve position indication which is not an operating restriction nor assumed as initial conditions for a design basis accident or transient analysis.

These lights do not control any equipment nor are they controlled by plant operators to mitigate any accident or event. Therefore, they do not meet criteria 2.

Prairie Island Units 1 and 2 13 2/2/02 Package 3.7 Part D

NSHD Change category number Discussion Of Change 3.7 LR 29 (continued)

Criterion 3: A structure, system, or component that is part of the primary success path and which functions or actuates to mitigate a design basis accident or transient that either assumes the failure of or presents a challenge to the integrity of a fission product barrier:

These lights are not a structure, system, or component that are a primary success path or actuates to mitigate a design basis accident. These lights only provide a visual aid for the control room operators to monitor AFW valve position.

Therefore, they do not meet criteria 3.

Criterion 4: A structure, system, or component which operating experience or probabilistic risk assessment has shown to be significant to public health and safety.

Again, these lights only provide a valve status of open or closed. The do not have any initiating signals nor generate any to actuate valve position or throttling. There has not been any operating experience or probabilistic risk assessment issues at PI for these lights. Therefore, they do not meet criteria 4.

Based on the above, these lights can be relocated to a Licensee Controlled Document.

Prairie Island Units I and 2 14 2/2/02 Part D Package 3.7

Package 3.7 NSHD Change category number 3.7-M Discussion Of Change 030 CTS 3.4.D. CTS requires the plant to meet secondary coolant radiochemistry requirements while in MODES 1, 2, and 3.

When these limits are not met the plant is required to go to MODE 4 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. These requirements have been conformed to the more restrictive requirements of NUREG 1431 by applying the radiochemistry limits in MODE 4 and requiring the plant to go to MODE 5 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />. This change is acceptable since it will not cause any unsafe plant operations and is consistent with current plant operating practices when radiochemistry limits are not met in MODE 4.

031 Not used.

Prairie Island Units 1 and 2 2/2/02 Part D 15

NSHD Change category number Discussion Of Change 3.7 R

032 CTS 3.4 C and 4.8.C. This specification provides requirements for the plant Steam Exclusion System. The Steam Exclusion System LCO and SR requirements have been relocated to the TRM since the system does not meet the criteria of 10 CFR 50.36 for inclusion in the Technical Specifications.

This system is an installed system for preventing steam from high energy line breaks from reaching safeguards equipment; thus it does not meet 10 CFR 50.36 (c)(2)(ii) Criterion 1 or 2.

The Steam Exclusion System is an installed system. However, it does not mitigate accidents and thus is not a primary success path for mitigating accidents. Therefore, the Steam Exclusion System does not meet 10 CFR 50.36 (c)(2)(ii) Criterion 3.

The Steam Exclusion System is not considered in the plant IPE and it is not a system which operating experience or probabilistic risk assessment has shown to be significant to public health and safety. Therefore this system does not meet 10 CFR 50.36 (c)(2)(ii) Criterion 4.

L 033 CTS Table 3.5-2B, Functional Unit 5a and Table 4.1-1 B, Functional Unit 5a. CTS requires operability of the main steam line isolation valves manual switches at all times when in MODE 2. In the ITS, MODE 2 applicability is modified by a condition which does not require these switches to be operable when both MSIVs are closed. Since this change limits the applicability for these switches, this is a less restrictive change.

This change is acceptable since the steam line isolation function is met passively without these switches operable when both MSIVs are closed. This change conforms to the guidance of NUREG-1431.

034 CTS Table 3.5-2B, Note c and Table 4.1-1B, Note 23. The format of this note has been revised to conform to the guidance of NUREG-1431. The note has been restated but has the same meaning; therefore this is an administrative change.

M 035 CTS 3.4.D. For consistency with NUREG-1431, 3.7.18 action statements, the one hour to initiate actions necessary to place the unit in MODE 3 has been deleted. Since this change may require the plant to shutdown sooner, it is a more restrictive change. This change does not cause the plant to be operated in an unsafe manner.

A 036 CTS3.3.C.1. The CTS has separate specifications for single unit or two unit operations. The ITS is written such that the requirements are the same for single or two unit operation. Any differences are addressed in the Bases.

M 037 CTS 3.3.C.1.a.l. For consistency with the format guidance of NUREG-1431, the requirement for two CC pumps to be OPERABLE has been generalized to require two trains of CC to be operable. Since this may require more equipment to be operable, this is a more restrictive requirement. This change is acceptable since the requirement for two trains may increase plant safety.

Prairie Island Units 1 and 2 17 12/11/00 Package 3.7 Part D

Package 3.7 Discussion Of Change NSHD category LR M

Prairie Island Units 1 and 2 12/11/00 Part D Change number 3.7-038 CTS 3.3.C.1.a.2. Since the ITS specifies that a whole train is required to be OPERABLE, the definition of specific components required to be OPERABLE is unnecessary in the TS and therefore relocated to the Bases. This change is consistent with the guidance of NUREG-1431. Since the ITS Bases (under the Bases Control Program in Section 5.5 of the ITS) are licensee controlled, this change is less restrictive.

039 A new SR, 3.7.7.1, is included which requires that CC valves in flow paths to safety related equipment that are not locked, sealed, or otherwise secured in position, are in the correct position. Since this SR may require additional plant activities, it is more restrictive. This more restrictive change is included to make the PI ITS complete. This change is consistent with the guidance of NUREG-1431. This change is acceptable since it may increase plant safety.

Part D Package 3.7 NSHD Change category number Discussion Of Change 3.7 M

040 CTS Table 3.5-2B, Action 27. The CTS requirements for the main steam line isolation valve (MSIV) manual switches are included in the ITS LCO 3.7.2 requirements because: 1) LCO 3.7.2 is a new specification for PI which should include all applicable design features of the MSIVs; and 2) these switches directly operate the MSIV without any intervening logic circuitry.

CTS requires an inoperable MSIV manual switch to be restored to operability within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />. ITS LCO 3.7.2 requires the MSIVs (including switches) to be restored to operability within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> or be in MODE 2 within 14 hours1.62037e-4 days <br />0.00389 hours <br />2.314815e-5 weeks <br />5.327e-6 months <br />, close the valve within 22 hours2.546296e-4 days <br />0.00611 hours <br />3.637566e-5 weeks <br />8.371e-6 months <br /> and verify the valve to be closed once per 7 days.

Since this will require the plant to shut down much sooner, this is a more restrictive change. This change is acceptable since it places the plant in a safer condition sooner and does not introduce any unsafe plant operations or tests.

LR 041 CTS3.3.C.2. The new format of the PI ITS requires that each unit has two trains OPERABLE. The details of equipment required to define two OPERABLE trains is contained in the Bases. Therefore, these details are unnecessary in the TS and are relocated to the Bases. This change is consistent with the guidance of NUREG-1431. Since the ITS Bases (under the Bases Control Program in Section 5.5 of the ITS) are licensee controlled, this change is less restrictive.

NSHD Change category number Discussion Of Change 3.7 M

042 CTS3.3.D.1. For consistency with the format guidance of NUREG-1431, the detailed listing of equipment required to be OPERABLE has been generalized to require two trains of Cooling Water (CL) to be operable. Since this may require more equipment to be operable, this is a more restrictive requirement. This change is acceptable since the requirement for two trains may increase plant safety.

LR 043 CTS 3.3.D.1.a., b., and c..The new format of the PI ITS requires that each unit has two trains OPERABLE. The details of equipment required to define two OPERABLE trains is contained in the Bases and TRM. This change is consistent with the guidance of NUREG-1431.

This change also relocates the CTS requirements for non safeguards CL pumps to the TRM. The non-safeguards pumps do not detect RCS leakage, they are not an initial condition of a DBA, they are not components that are part of the primary success path for mitigation of a DBA and they are not significant to public health and safety; thus these pumps do not meet the Screening Criteria for inclusion in the ITS.

Relocating CTS requirements to the TRM or Licensee Controlled Document is less restrictive.

NSHD Change category number Discussion Of Change 3.7 A

044 CTS3.3.D.1.a. For clarity and consistency with the format requirements of NUREG-1431, the CTS requirements for safeguards CL pump inoperability have been restated as "No safeguards pumps OPERABLE for one train..." Since this statement is substantively the same as the CTS requirements and does not change any requirements for plant operation, this is an administrative change.

A 045 CTS 3.3.D.2.a.(1) and (2). CTS provides specific actions to be taken if two CL safeguards pumps are inoperable. These actions include cross train checks, verify support and supported relationships, and to ensure that there is not a loss of function in the CL system. Under the guidance and format of NUREG-1431, these specific actions are incorporated and verified under the Safety Function Determination Program (SFDP) as required by LCO 3.0.6 and 5.5.13, Safety Function Determination Program. This change is acceptable since the actions required to assure the plant is operated safely without loss of safety function is provided by the required Safety Function Determination Program. This change is consistent with the guidance of NUREG-1431. This is an Administrative change since the CTS requirements are consistent with those in the ITS.

046 CTS3.3.D.2.b.(1) and (2). CTS allow one CL header to be inoperable provided the vertical motor-driven CL is operable, but no time frame is defined within which this action is required to be completed. In the format of the ITS, some COMPLETION TIME is required to be defined for REQUIRED ACTIONS.

Under the requirements of ITS LCO 3.0.6, the other train will be verified to be operable, including the OPERABILITY of the diesel driven cooling water pump on the operable header. The vertical motor driven CL pump provides added assurance that there is a safeguards pump to supply the operable header.

Thus 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> is provided as the required time-frame in which the vertical motor driven CL pump must be verified to be operable. Since a specific time is specified, this change is more restrictive.

A 047 CTS 3.3.D.2.b.(1) and (2). CTS allow one CL header to be inoperable provided the horizontal CL pump is verified to be operable. These CTS actions include cross train checks, verifying support and supported relationships, and ensuring that there is not a loss of function in the CL system. Under the format and guidance of NUREG-1431, the horizontal pump will be relocated to the TRM as discussed in DOC LR3.7-43. In addition, the CTS requirements for verifying diesel generator operability and verifying the diesel driven pump operability are incorporated in LCO 3.7.8, Condition B.

048 A new SR, 3.7.8.1, is included which requires that CL valves in flow paths to safety related equipment that are not locked, sealed, or otherwise secured in position, are in the correct position. This SR is modified by a Note that clarifies that the CL system is not inoperable if the flow path to an individual component is isolated. The operability of each TS system affected by an isolated component would have to be evaluated under the TS definition of OPERABILITY. Since this SR may require additional plant activities, it is more restrictive. This more restrictive change is included to make the PI ITS complete. This change is consistent with the guidance of NUREG-1431. This change is acceptable since it may increase plant safety.

M 049 CTS3.3.D.2.c. CTS allow one Safeguards Traveling Screen to be inoperable provided a sluice gate is open but no time frame is defined within which this action is required to be completed.

In the format of the ITS, some COMPLETION TIME is required to be defined for REQUIRED ACTIONS. Since there is a redundant Safeguards Traveling Screen and an inoperable Safeguards Traveling Screen may not have an immediate loss of function, four hours was selected as a reasonable time to complete this action. Since a specific time is specified, this change is more restrictive. This change is included to make the ITS complete and will maintain the plant in a safe condition.

Prairie Island Units 1 and 2 12/11/00 Part D 051 CTS3.3.D.2.d. CTS allow both Safeguards Traveling Screens to be inoperable provided a sluice gate is open but no time frame is defined within which this action is required to be completed. In the format of the ITS, some COMPLETION TIME is required to be defined for REQUIRED ACTIONS. It is unlikely that both Safeguards Traveling Screens would become inoperable simultaneously; therefore when the first Safeguards Traveling Screen became inoperable the action to open the sluice gate would already have been taken and this CONDITION would likely only require administrative verification that a sluice gate had previously been opened. If both Safeguards Traveling Screens are inoperable, expeditious action is required to remedy the situation; thus one hour was selected as a reasonable time to complete this action. One hour is consistent with the time allowed in CTS 3.0.C to take action prior to shutdown when the plant is in conditions not addressed by TS. Since a specific time is specified, this change is more restrictive. This change is included to make the ITS complete and will maintain the plant in a safe condition.

054 CTS 3.13.A.1. The requirement for CRSVS operability has been revised to include MODES 1, 2, 3 and 4 and during movement of irradiated fuel.. When neither unit is in one of these modes or conditions, the CRSVS is not required to perform a safety function. Design basis accidents with radiological releases are not analyzed for MODES 5 and 6.

CRSVS operability during CORE ALTERATIONS is not required because:1) borated water prevents a problem with inadvertent rod withdrawal; 2) operators have sufficient time to identify and terminate a dilution accident; and 3) while shutdown, the borated water will maintain any misloaded assembly in a safe condition. The applicability would not require the CRSVS to be operable during handling of new fuel.

This is acceptable since new fuel does not contain any fission gas inventory. This change is consistent with TSTF-51. Since this change allows CRSVS inoperability during some modes, this change is less restrictive.

M 055 CTS 3.13.A.1. For consistency with NUREG-1431, the one hour to initiate actions to shut down has been deleted. This is acceptable since the Required Actions already allow time to take actions and prepare for shutdown if required.

This change is consistent with TSTF-51. Since this change allows CRSVS inoperability during CORE ALTERATIONS, this change is less restrictive.

A 057 CTS 3.13.A.1 and 2. NUREG-1431 provides separate action statements for CRSVS during plant operation (MODES 1, 2, 3, and 4) and irradiated fuel handling operations. For clarity a new statement is included to show the changes in the CTS markup.

Since this statement by itself does not change any CTS requirements, it is an administrative change.

M 058 CTS 3.13.A.1. CTS provisions which allow two hours to take actions with respect to fuel handling have been deleted since NUREG-1431 requires immediate termination of irradiated fuel handling activities. If only one train of CRSVS is inoperable, the option of placing the operable CRSVS train in service is included. Immediate termination of irradiated fuel handling and placement of the operable CRSVS train in service are acceptable since they maintain the plant in a safe condition.

These changes are more restrictive since required actions are required to occur sooner.

059 A new specification, 3.7.11, is included which requires two safeguards chilled water trains to be operable. Since this new specification places additional TS requirements on the plant, this change is more restrictive. This change is acceptable because the plant currently operates this system as a support system to the CRSVS.

M 060 New SR 3.7.8.3 requires monthly verification that the CL diesel fuel oil supply meets the required limits. CTS does not explicitly require verification of the diesel CL pump fuel oil supply; therefore, this is a more restrictive change. This change is acceptable since the plant currently checks the fuel oil supply and this will not introduce any unsafe plant operations or tests. This change is consistent with the intent of NUREG-1431 as applied to diesel generators.

M 061 Two new SRs, 3.7.11.1 and 3.7.11.2, are included which requires verification each SCWS train actuates on an actual or simulated actuation signal and OPERABILITY of SCWS components in accordance with the ITS program. Currently the plant performs these tests. However, these SRs will make these verifications TS requirements; thus, these changes are considered more restrictive. These more restrictive changes are included to make the PI ITS complete.

063 CTS 3.6.E.2 and 3. The details of inoperability conditions and controls for the ABSVS have been relocated to the TRM and Bases. These specification details are unnecessary since the Specification requirement for ABSVS OPERABILITY in PI ITS 3.7.12 and associated ACTIONS envelopes these requirements. A general discussion of these requirements are included in the Bases for completeness. The specific requirements are included in the TRM to assure that they are readily accessible to the operators. This change is consistent with the format and philosophy of NUREG-1431.

066 CTS 3.8.B.1.c The ITS, consistent with CTS 3.8.E.2.a, requires the boron concentration to be maintained at 1800 ppm at all times when spent fuel is stored in the spent fuel pool.

Therefore the applicability is expanded beyond involving a spent fuel cask containing fuel. Since the applicability for this requirement is consistent with CTS 3.8.E.2.a, this is an administrative change. This change is consistent with other CTS requirements and does not cause the plant to operate in an unsafe manner.

LR 067 CTS 3.8.B.1.a. The CTS requirement to continuously monitor radiation levels in the SFP area during fuel handling was not included in the PI ITS. No screening criteria apply for this requirement because the process variable of the LCO is not an initial condition of a DBA or transient analysis. The SFP radiation levels only provide a secondary indication of a SFP area problem. Other ITS LCOs, such as SFP level and boron concentration, provide adequate assurance that all accident analysis assumptions are met. Since this Specification only applies during fuel handling, if an accident were to occur, the personnel stationed in the SFP area would be immediately aware of the problem. Therefore, this'specification does not satisfy any of the NRC Final Policy Statement TS screening criteria and is relocated to the TRM. This change is consistent with the guidance of NUREG-1431.

NSHD Change category number Discussion Of Change 3.7 LR 068 CTS 3.8.B.1.b. The requirement to test fuel handling cranes prior to fuel handling is not included in the PI ITS. No screening criteria applies for this requirement because the fuel handling crane limit switches, interlocks and alarms are not installed instrumentation that is used to detect and indicate in the control room, a significant abnormal degradation of the RCS. The crane testing requirements are not related to an initial condition of a Design Basis Accident or Transient analysis that either assumes the failure of or presents a challenge to the integrity of a fission product barrier. The equipment which is the subject of this specification requirement is not a part of the primary success path for mitigation of a DBA or Transient. If a fuel handling accident occurs, other plant features such as the SFP water and SFPSVS are the primary success paths. Therefore, this specification does not satisfy any of the NRC TS screening criteria and is relocated to the TRM. This change is consistent with WCAP-1 1618 and the guidance of NUREG-1431.

R 069 CTS 3.8.C. The CTS requirement to limit the number of recently discharged fuel assemblies stored in the small pool (Pool 1) is not included in the PI ITS. This specification does not contain requirements for installed instrumentation. This specification does not address an operating restriction that is an initial condition of a DBA or Transient analysis that either assumes the failure of or presents a challenge to the integrity of a fission product barrier. This operating restriction on fuel storage is not a structure, system or component. Therefore, this specification does not satisfy any of the NRC Final Policy Statement TS screening criteria and is relocated to the TRM.

L 072 CTS 3.8.D.2. This proposed change will delete the requirement to demonstrate operability of the redundant SFPSVS train when one train is inoperable. This change is acceptable because there is a low probability of a fuel handling accident in the 7 days that fuel movements are allowed to continue and the redundant train is required by ITS to be tested on a 31 day schedule. Further testing when one train fails is not necessary.

In addition, the ITS requires in Action B that if the Required Actions and associated Completion Time of Condition A is not met then place the OPERABLE SFPSVS train in operation immediately and to also immediately suspend movement of irradiated fuel assemblies in the spent fuel pool enclosure.

This change is consistent with the guidance of NUREG-1431.

Since this change may require less testing, it is a less restrictive change.

The CTS inspection and testing requirements do demonstrate the snubbers are OPERABLE. However, the ISI program, required by 10CFR50.55a, provides requirements for testing of snubbers. Prairie Island is required to comply with the provisions of 10CFR50.55a and therefore has an ISI program.

This ISI program is reviewed, approved and inspected by the NRC. These controls are adequate to the required inspection and testing to demonstrate snubber operability. Therefore, PI programs and NRC regulations contain adequate requirements for snubbers without repeating them in the TS. Since the snubber requirements will be relocated to the TRM, changes will be under the controls of 1 OCFR50.59. This change is consistent with the guidance of NUREG-1 431.

These valves are not leak detection equipment, they are not process variables, they are not a part of the primary success path for mitigation of an accident and these valves have not been found to be significant to the public health and safety. Therefore these valves do not meet the criteria of 10 CFR 50.36 for inclusion in the TS. Thus the SR for testing these valves has been relocated to the TRM. This change is consistent with the guidance of NUREG-1431. However, this change is acceptable since the TRM is under the regulatory controls of 10 CFR 50.59.

085 CTS 4.8.A.1. The CTS requirement to demonstrate full flow to the SG each refueling shutdown is not included in the ITS. This change is acceptable because the other AFW system SRs assure that full flow will reach the SGs. ITS SRs which implement CTS requirements include verification that each AFW pump develops the required head at the test flow point, verification that automatic valves actuate to the correct position on an actual or simulated signal, and verification of the flow path from the CSTs to each SG after each shutdown extending beyond 30 days. Also a new SR is included, SR 3.7.5.1, which requires verification that each valve in the AFW flow path that is not locked, sealed, or otherwise secured in position, is in the correct position. The combination of these SRs provide the necessary assurances that full AFW flow will reach the SGs.

Furthermore this system is used as an operational system to feed the SGs during plant startup until the main feedwater pumps can be started (approximately 2% power); thus if AFW flow was not provided to the SGs, plant startup would not be able to proceed. Therefore this requirement is not included in the ITS. This change is consistent with the guidance of NUREG-1431.

088 CTS 4.8.A.6. The CTS requirement to verify the position of valves which are locked in position is not included. Some valves in the AFW system are locked, sealed, or otherwise secured in position under administrative controls to assure that AFW flow will not be obstructed or altogether stopped. Since these locks, seals or other secure means are under administrative control, it is unnecessary to verify these valves are secured in the proper position on a regular monthly schedule. Therefore this requirement is not included. Since this change places less requirements on plant operations, it is a less restrictive change. This change is consistent with the guidance of NUREG-1431.

L 089 CTS 4.8.A.7. The CTS requirement to verify the normal AFW flow path to the SGs after each cold shutdown is not included in the PI ITS. At PI the AFW system is used for each normal unit startup and shutdown. Therefore, further documented verification is not necessary. This change is consistent with the guidance of NUREG-1431 which states, "This SR is not required by those units that use AFW for normal startup and shutdown." Since this change requires less plant testing, it is a less restrictive change.

In accordance with SR 3.0.2 this surveillance interval is fixed at this maximum and is not allowed to be extended beyond 24 months. A review of the six year period from January 1990 to the end of 1995 showed that no problems were encountered during the performance of these tests.

Therefore extension of this interval up to 24 months is acceptable. This change is consistent with the guidance of GL-91-04. Since this change will allow less frequent performance of this test, this change is less restrictive. This change is consistent with the guidance of NUREG-1431.

L 092 CTS 4.8.A.8, 4.5.A.4 and 4.5.A.5. The phrase "that is not locked, sealed, or otherwise secured in position" is included to make this SR consistent with the guidance of NUREG-1431.

This is acceptable, since valves that are physically and administratively secured in position will very likely be in the correct position when system performance is required. Since this may require less verification of plant equipment, this change is less restrictive.

The CTS requirement to perform this SR using a test signal has been broadened to include use of an actual signal. If the system starts due to receipt of an actual signal, this is adequate verification of system operability. Further testing within that test interval should not be required using a test signal. Therefore this change is acceptable. This change is consistent with the guidance of NUREG-1431. Since this change may require less testing, it is a less restrictive change.

The CTS requirements have also been split into two SRs for clarity. Currently, the check damper operability is verified monthly under the provisions of the CTS. Since this verification does not involve an actuation signal, this test is specified as a separate SR.

This is acceptable since plant experience has shown that these valves usually pass their surveillance when performed in accordance with the CTS. Thus extension of the test interval to IST requirements is justified.

The testing interval for these valves remains under NRC control through NRC review and approval of the IST program. Since this change will require less testing, it is a less restrictive change.

LR 099 CTS 4.5.A.5.b. The requirements for diesel engine inspections will be relocated to the TRM and have not been included in the PI ITS. ITS 3.7.8 requires the necessary CL trains, which includes applicable pumps, to be OPERABLE. The ITS definition of OPERABILITY states, "A system, subsystem, train, component, or device shall be OPERABLE... when it is capable of performing its specified safety function(s) and when all necessary attendant instrumentation, controls, normal or emergency power, cooling and seal water, lubrication, and other auxiliary equipment that are required for the system...

to perform its specified safety function(s) are also capable of performing their related support functions(s)." The definition of OPERABILITY and the requirements of ITS LCO 3.7.8 are adequate for ensuring the diesel driven CL (DDCL) pump is OPERABLE. Therefore the LCO requirement for the DDCL pump to be OPERABLE mandates performance of inspections to the extent that they are required to assure operability of the pump. Thus, these requirements are relocated to the TRM.

Relocating these requirements to the TRM maintains consistency with NUREG-1431.

NSHD Change category number Discussion Of Change 3.7 LR 100 CTS 4.4.B.3.c. CTS requires verification that the ABSVS actuates on a high radiation signal in addition to an SI signal.

Following an accident, the ABSV system will be actuated by an SI signal, and therefore, actuation by the high radiation signal is not required for accident mitigation. The high radiation signal is not part of RCS leakage detection instrumentation; it is not a variable, design feature or operating restriction that is an initial condition of an accident; it is not a system, structure or component that is part of the primary success path for mitigating an accident; and it is not a structure, system or component which has been shown to be significant to the public health and safety. Thus this signal does not meet the TS Selection Criteria of 10CFR50.36 and is not included in the ITS. This requirement is relocated to the Offsite Dose Calculation Manual (ODCM). Since the ODCM is under licensee control this is a less restrictive requirement. However, this change is acceptable because the ODCM is a program required by ITS Section 5.5 and is under the regulatory controls of 10CFR50.59.

L 101 CTS 4.14.A and 4.15.A. The CTS requirement to test automatic initiation of this system at least every 18 months is not included. The ITS will require this system test every 24 months which will allow extension of the PI refueling outage cycle. A review of past test results for this system test showed that no problems were encountered during the performance of the test. Therefore, extension of the test to the refueling shutdown interval (up to 24 months) is acceptable.

Specific details for conduct of ventilation filter tests have been relocated to the Ventilation Filter Test Program in accordance with the requirements of PI ITS Section 5.5, Ventilation Filter Test Program. Since this test program is required by the TS, these requirements remain under regulatory controls. This change is consistent with the guidance of NUREG-1431. Since this change removes specific requirements from the TS, it is a less restrictive change.

L 103 CTS 4.14.B.1.c and 4.15.B.1.c. The test interval for verification of fan performance has been extended to once per operating cycle on a STAGGERED TEST BASIS (STB). Past experience has shown that this system usually passes the fan flow test.

Fan performance usually changes slowly over long periods of time which would allow prediction of unacceptable performance before a test is actually failed. Other system tests verify that the fans move air. This test verifies that the air movement is within the specified limits. If the fan fails the test, it may still move air and continue to perform most of its safety function. Therefore, extension of the interval to 24 months on an STB is acceptable.

The change to 24 months is consistent with the guidance of Generic Letter 91-04. The change to an STB is consistent with the guidance of NUREG-1431. Since this change will require less testing, it is less restrictive.

Since a train may include more equipment than a circuit, this is considered a more restrictive requirement. This change is consistent with the guidance of NUREG-1431. This change is incorporated to conform the PI ITS to the philosophy of the ISTS and make it complete.

105 CTS 4.4.E. The CTS requirement to test the auxiliary building normal ventilation system isolation valves is included in the requirements of SR 3.7.12.4. Since no substantive changes have been made in this clarification, this is an administrative change.

106 CTS 4.19. The requirements to inspect AB crane lifting devices prior to handling heavy loads is not included in the PI ITS. No screening criteria apply for this requirement because the AB crane lifting devices are not installed instrumentation that is used to detect and indicate in the control room a significant abnormal degradation of the RCS. The AB crane lifting device inspection requirements are not related to an initial condition of a Design Basis Accident or Transient analysis that either assumes the failure of or presents a challenge to the integrity of a fission product barrier. The equipment which is the subject of this specification requirement does not in any way mitigate the consequences of an accident and therefore is not a part of the primary success path for mitigation of a DBA or Transient.

Therefore, this specification does not satisfy any of the NRC Final Policy Statement TS screening criteria and is relocated to the USAR (TRM). This change is consistent with WCAP-1 1618 and the guidance of NUREG-1431.

M 107 CTS 4.20. A new SR, 3.7.17.1 is included to require verification of each assembly prior to moving the assembly. This change is acceptable because this verification is currently performed in accordance with plant procedures. Since this is a new TS requirement, it is a more restrictive change. This change is consistent with the guidance of NUREG-1431.

M Prairie Island Units 1 and 2 2/2/02 Change number 3.7-108 CTS Table 4.1-2B, Item 15 and Note 5. CTS allows this surveillance to be performed every six months when the activity level is less than 10% of the limit. This change will conform this SR to NUREG-1431 SR 3.7.18.1 requirements which require the surveillance to be performed every 31 days regardless of activity level. This change is acceptable since it will not cause any unsafe plant operations or tests and the plant currently performs this testing within a 31 day frequency.

NSHD Change category number Discussion Of Change 3.7 LR 112 CTS Table 4.1-2B, Items 14, 16 and Note 6. CTS requirements to sample the Secondary coolant gross Beta Gamma activity (Item 14) and Secondary coolant chemistry (Item 16) have been relocated to the TRM. These sampling tests are not leak detection equipment, they are not process variables, they are not a part of the primary success path for mitigation of an accident and these tests have not been found to be significant to the public health and safety. Therefore these sampling tests do not meet the criteria of 10 CFR 50.36 for inclusion in the TS. Item 14 is not the subject of a TS in NUREG-1431, and since it does not meet the criteria of 10 CFR 50.36 (c)(2)(ii) it is not included in the ITS. Item 16 is related to the Secondary Water Chemistry Program in NUREG 1431 Section 5.5 and thus is not the subject of a TS in NUREG-1431. In accordance with the PI LAR dated December 14, 1995 (LA 141/132), PI does not propose to include a Secondary Water Chemistry Program in the ITS.

Thus, Item 16 has been relocated to the TRM. Since the SR for these tests are not in ITS, this is a less restrictive change.

However, this change is acceptable since the TRM is under the regulatory controls of 10 CFR 50.59.

113 CTS 4.5.A.4.a, 4.5.A.5.a, 4.5.B.3.e, 4.5.A.B.3.f. The CTS has been revised to change phrase "refueling outage" or "refueling shutdown" to 24 months. As a result, DOC A3.4 113 was generated to justify this change. Throughout the ITS submittal, all SRs which are intended to be performed during refueling shutdown or refueling outage interval performance have a required Frequency of 24 months. The intent of the ITS is to allow PI operating cycles to extend up to 24 months. CTS 4.0.A.2 states that SRs with a "refueling shutdown" Frequency may not be performed at an interval exceeding to 24 months. ITS SR 3.0.2 retains CTS flexibility by allowing SR testing interval to be adjusted by 25%. CTS restrictions on this flexibility have also been retained in that ITS SR 3.0.2 states, "... the specified Frequency for each SR is met, except for SRs with a specified Frequency of 24 months, if the Surveillance is performed within 0.75 to 1.25 times the interval specified...." ITS SR 3.0.2 further reinforces this limitation by later stating, "The specified Frequency is met for each SR with a specified Frequency of 24 months if the Surveillance is performed within 24 months

." The proposed ITS does not intend for any SRs with 24 month Frequency to exceed 24 months and thus default PI operating cycles are limited to 24 months. Since the intent of the CTS Frequencies of "refueling outage" or Refueling Shutdown" are the same as the ITS, discussed above, this is considered to be an Administrative change.

114 CTS Table 3.5-2B, Action 27. New Note added allowing separate Condition entry for each MS IV. CTS would require entry into LCO 3.0.C when two MSIVs were inoperable at the same time. This change will allow continued plant operation with inoperabilities of both MSIVs, providing the Required Actions are met. This change is acceptable since the Required Actions assure that the safety function of the MSIVs are maintained.

M 115 CTS 3.3.D.1.d. The CTS has been revised changing the volume of fuel oil supply required for the CL diesel from 19,000 to 19,500 gallons. Recent calculations have determined that 19,500 gallons are required to meet the design basis for the diesel driven CL pumps. This is a more restrictive change since the ITS divides the CTS diesel fuel oil volume into two separate Specifications. One Specification for the CL diesel fuel oil supply (3.7.8) and another for the diesel generator fuel oil supply (3.8.3). This change is acceptable since it envelopes the CTS fuel oil volume requirements The two separate fuel oil volume requirements ensure there is an adequate supply of fuel oil in order for the diesel driven CL pumps to perform their intended function and at the same time not consume fuel oil required to meet the EDGs needs.

116 CTS 4.8.B. A new SR has been added to manually cycle the SG PORV block valves every 24 months. The purpose of the SR is to manually cycle both PORV block valves closed and open to demonstrate their capability to perform this function. This change is considered to be a more restrictive since the CTS does not require an SR for manually cycling these block valves on a specific frequency. Adding this SR is acceptable since it ensures that the block valves will perform their intended function when required. This change is consistent with NUREG-1 431.

L 117 CTS 3.3.C.1.b. CTS states that. "any one of the following conditions of inoperability may exist..." This requirement prevents two or more of the listed conditions from existing at the same time to assure that there is no loss of safety function. The limitation that only one condition of inoperability may exist is not explicitly stated in ITS. In ITS, the system is treated as "trains" rather than individual components. The ITS assures there is no loss of safety function by requiring one train to be operable at all times.

Multiple components within a train may be inoperable since the whole train is considered inoperable when one component is not operable. Since the ITS would allow a train, instead of individual components as in the CTS, this change is considered to be a less restrictive change.

118 Add new Condition and LCO Note. The LCO note allows the control room boundary to be open intermittently under administrative control. This.is acceptable since the ability to restore the boundary in the event of a DBA is always available in this condition. In addition, Condition B requires that with two CRSVS trains to be inoperable due to control room boundary in Modes 1, 2, 3, and 4, restore the control room boundary within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. Although less restrictive than the CTS, this change is applicable to PI since requiring the plant to enter LCO 3.0.3 when the ventilation envelope is not intact is excessive and not appropriate. The Completion Time of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> is also acceptable since it is a reasonable time for routine repairs and due to the low probability of a DBA occurring during this time.

M 119 CTS Table 3.5-2B. CTS Table 3.5-2B, Action 27 requires that if the inoperable MSIV cannot be restored to OPERABLE status within a specific time, place the unit in at least HOT SHUTDOWN and close the associated valve. There is no specific time required to close the inoperable MSIV. ITS LCO 3.7.2, Condition D has been added. This Condition requires that if the inoperable MSIV cannot be closed within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />, then be in Mode 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and Mode 5 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. Since the CTS only requires that the inoperable MSIV be closed and does not require any shutdown track, this is considered to be a More Restrictive change.

I I

Since the MSIVs are required to be OPERABLE in MODES 2 LR-I i

and 3, the inoperable MSIVs may either be restored to OPERABLE status or closed.

When closed, the MSIVs are already in the position required by the assumptions in the safety analysis.

ACTIONS G.1 and C.2 (eontinue-d)

The -8+ hour Completion Time is consistent with that allowed in Condition A for one MSlV inoperable.

For an inoperable MSIVW& that cannot be restored to OPERABLE status within the specified Completion Time, but isa-re closed, the inoperable MSIVs must be verified on a periodic basis to be closed.

This is necessary to ensure that the assumptions in the safety analysis remain valid.

The 7 day Completion Time is reasonable, based on engineering judgment, in view of MSIV status indications available in the control room, and other administrative controls, to ensure that these valves are in the closed position.

D.1 and D.2 If the MSIVs cannot be restored to OPERABLE status or are not closed within the associated Completion Time, the unit must be placed in a MODE in which the LCO does not apply.

To achieve this status, the unit must be placed at least in (continued)

In MODE 4, a steam generator and the SG PORV are not relied upon for heat removal.

In MODE 5 or 6, an SGTR is not a credible event.

ACTIONS A.1 With one required SG PORVADV---inre inoperable, action must be taken to restore OPERABLE status within 7 days.

The 7 day Completion Time allows for the redundant capability afforded by the remaining OPERABLE SG PORVABV lines, a nonsafety grade bakup in the Steam DumpBypass System, and MSSVs.

Required Action A.1 is modified by a Note indicating that LCO 3.0.4 does not apply.

B.1 With two or-mfoie-SG PORVsA9V lines inoperable, action must be taken to restoreall but one SG PORVAD1V*l-i-ne to OPERABLE status.

Since the block valve can be closed to isolate aft SG

PORVADV, some repairs may be possible with the unit at power.

The -241 hour Completion Time allows time to PA3.7-353 plan an orderly shutdown of the unit and is reasonable to repair inoperable ADV lines, based on the availability of the Steam Dump Bypass System 1R-111 and MSSVs, and the low probability of an event occurring L-during this period that would require the SG PORVABV- -lines.

Manually Ccycling the block valve both closed and open demonstrates its capability to perform this function.

Performance of inservice testing or use of the block valve during unit cooldown may satisfy this requirement.

This exception allows the system to be out of its normal standby alignment and temporarily incapable of automatic initiation without declaring the train(s) inoperable.

Since AFW may be used during MODES 2, 3 and 4 operations for steam generator level control, and these manual operations are an accepted function of the AFW system, OPERABILITY (i.e., the intended safety function) continues to be maintainedthe SR is-no required in MODE 4. in MODE 4, the required AFW train is already aligned and operating.

in MODE 4, the required putmp is already operating and the autostart function is not required. Since this PA3.7 test is performed during unit shutdown, the turbine driven AFW pump is not actually started, but the components necessary to assure it starts on an actual or simulated AFW pump start signal are demonstrated to be OPERABLE.

This test is considered satisfactory if control board indication and subsequent visual observation of the equipment demonstrate that all components have operated properly.

CSTs B 3.7.6 B 3.7 PLANT SYSTEMS B 3.7.6 Condensate Storage Tanks (CSTs)

PA3.7-201 CL3.7-141 BASES BACKGROUND Three 150,000 gallon CSTs (total) are shared via a common header between the 2 units. Unit 1 has 1 tank (11) and Unit 2 has 2 tanks (21 and 22).

The CSTs provides a nonsafety grade source of water to the steam generators for removing decay and sensible heat from the Reactor Coolant System (RCS).

A backup safety grade source of water is provided by the safety-related portion of the Cooling Water (CL)

System (LCO 3.7.8) via either the Emergency Cooling Water Line or the emergency bay sluice gates.

Since water supplied from the CL System is of lower ICL3.7-254 purity, its use is considered less desirable under normal conditions than the higher purity condensate water from the CSTs.

However, if needed, the operator can lineup the Cooling Water supply by opening the associated CL supply motor operated valve (MOV) and closing the associated CST supply MOV for each auxiliary feedwater pump.

The CSTs provides a passive flow of water, by gravity, to the Auxiliary Feedwater (AFW)

PA3.7-247 System (LCO 3.7.5).

The steam produced is released to the atmosphere by the main steam safety valves, ei-the steam generator power operated relief valves or the atmospheric dump valves.

EachT-he AFW pumps operates with a continuous recirculation to at-he CST.

When the main steam isolation valves are open, the preferred means of heat removal is to discharge steam to the condenser by the nonsafety grade path of the steam dumpbypass valves.

The condensed steam '-smay be returned to the CSTs by the (continued)

b. Failure of the steamn driven AFW pump (requiring a longer time for cooldown using only 0n"mtr rie These are not usually the limniting failures in terms of consequenees for these events.

A nonlimiting event eonsidered in CST inventory determinations is a break in either the main feedwater or AFW line near where the two join.

This break has the potential for dumping condensate until terminated by operator action, since the Emergency Feedwater Actuation System would not detect a differenee in pressure between the steam generators for this break location.

This loss of eondensate inventory is partially eompcnsated for by the retention of steam generator inventory.

The 100,000 gallon CSTs useable volume requirement for each unit in MODE 1, 2, or 3 is sufficient to:

The 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> is reasonable due to the low probability of an event occurring during this time requiring MSSV operation. TSTF - 235, which mostly deals with graduated plant power levels associated with inoperable MSSVs, has generally not been incorporated in this Specification and Bases. However, the statement of the LCO has been revised to be consistent with TSTF - 235 since this is an improvement which applies without the provisions for graduated power levels.

CL 112 Since PI intends to require all MSSV to be operable, it is unacceptable to allow more than one MSSVs to be inoperable at any given time and keep the plant operating. Therefore, use of Separate Condition entry is not appropriate and has not been included in the PI ITS.

PA CL CL 127 PI has two trains of AFW for each unit. Therefore, this specification is written to require two AFW trains.

128 This change adds a Note to the LCO and Bases which will allow the system to operate and still be considered OPERABLE for safety related requirements. PI requires this Note to incorporate NRC TS interpretation issued to NSP October 16, 1997. Since PI has only two trains of AFW per unit and the AFW system is required to operate as part of normal plant startup and shutdown, this change is required. This change is consistent with TSTF-245, Revision 1 (See TA3.7-136).

129 CTS only requires the AFW system to be operable in MODES 1,2, and 3; therefore the applicability requirements for MODE 4 are not included. Also, the related clause for Condition B and all of Condition E have been deleted.

Part F Package 3.7 Difference Difference Category Number 3.7-x Justification for Differences 130 This ITS conversion LAR proposes to require testing of the SG PORV at the interval specified in the IST Program. The IST Program, which is approved by the NRC, currently requires the SG PORV to be tested quarterly. A change in this interval would be reviewed and approved by the NRC. This interval is more frequent than the bracketed 18 month interval in NUREG-1431.

This change is also discussed in DOC L3.7-95.

2/2/02 Package 3.7 Part F 7

Package 3.7 Difference Difference Category Number 3.7-Justification for Differences 141 PI has three condensate storage tanks which are interconnected to commonly serve both PI units. Thus, these tanks form a system which is shared between PI Units 1 and 2. Therefore, an "s" has been added to "CST" in the title and Condition A to show it is the system of tanks, not just one tank, that is under consideration.

CL TA CL This change incorporates approved traveler, TSTF-140 which requires the CSTs to be operable rather than specifying tank contents.

143 CTS requires CSTs operable when either unit is in MODE 1, 2, or 3. Therefore, MODE 4 operability requirements are not included in the PI CTS. This is acceptable since in MODE 4, the pressure and temperature limitation are such that the probability for a design basis event requiring plant cool down using SG PORVs is low. Also, in MODE 4 the RHR system is available to provide adequate decay heat removal. The associated Bases have also been modified to be consistent with these changes.

Modification of the Bases inserts have been made to reflect the PI AFW system design features.

TA CL 151 Prairie Island Units I and 2 Two SRs and associated Bases, which are not provided in NUREG-1431, are included to incorporate CTS requirements for testing CL pump operability. Since these pumps may not be normally operating, operability testing is required.

Package 3.7 Difference Difference Category Number 3.7-Justification for Differences 155 Not used.

CL CL 156 New Action Statements A and B are included to incorporate CTS requirements for the safeguards traveling screens. These requirements are the same as CTS except for changes required to conform to the ISTS format (such changes were addressed in Part D, Discussion of Changes to CTS). Associated Bases have also been provided.

157 Prairie Island Units 1 and 2 The Action Statements and associated Required Actions and Completion Times have been modified to incorporate CTS requirements to assure that at least one emergency bay sluice gate is open. These requirements are the same as CTS except for changes required to conform to the ISTS format (such changes were addressed in Part D, Discussion of Changes to CTS, for this Section). Associated Bases have also been provided.

2/2/02 Part F 15

Package 3.7 Difference Difference Category Number 3.7-PA Justification for Differences 162 The system which provides a protected environment from which operators can control the unit following an uncontrolled release of radioactivity at P1 is called the Control Room Special Ventilation System (CRSVS).

Thus, this specification title, LCO, affected Action Statements, SRs and associated Bases have been revised to incorporate this change.

163 Not used.

CL 164 Bracketed MODES 5 and 6 are not included in the Applicability, affected Action Statements and Bases. As stated in the ISTS Bases for this specification, these MODES are applicable when the plant has external waste gas storage tanks which could rupture. Since P1 does not have external waste gas storage tanks, these MODES are not applicable.

Prairie Island Units 1 and 2 2/2/02 Part F 17

Part F Package 3.7 Difference Difference Category Number 3.7-PA PA 171 172 Justification for Differences The SCWS at PI is a shared system which supports the operation of both units. Since this system supports the CRSVS which is not required to be operable in MODES 5 and 6, the SCWS is likewise not required to be operable in MODES 5 and 6.

The PI Auxiliary Building Special Ventilation System (ABSVS) is the system which most closely resembles the Emergency Core Cooling System Pump Room Exhaust Air Cleanup System. Therefore, the name of this specification has been revised to ABSVS in the title, LCO, affected Action Statements, SRs and throughout the associated Bases.

173 Not used.

Prairie Island Units 1 and 2 2/2/02 Part F Package 3.7 20

Part F Package 3.7 Difference Difference Justification for Differences Category Number 3.7 CL 346 PI has two different designs of stored spent fuel which require two separate figures in Specification 3.7.17.

Thus, this discussion is modified to identify the two types of spent fuel and reference the PI specific figures.

CL 347 The Bases ASA discussion has been replaced with discussion derived from the CTS Bases. This discussion differs from NUREG-1431 since PI has been licensed to credit the soluble boron in the spent fuel pool.

PA 348 Specification 3.7.8 Required Actions A.land B.2 have been modified by the addition of the clause, "10 days from discovery of failure to meet the LCO". Similarly, required Action D.1 has been modified by the addition of the clause, "9 days from discovery of failure to meet the LCO". These additions are necessary because of the unique requirements of the Prairie Island Cooling Water specification requirements and to make the Completion Times consistent with similar ISTS Completion Time requirements. The associated Bases have also been revised to explain these additional allowed outage time limitations.

349 Not used.

350 Not used.

CL 351 The CTS also requires a minimum boron concentration when loading and unloading spent fuel storage casks.

For completeness, these activities are included in the Bases LCO discussion.

The ISTS Completion Time of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> was based on a 4 loop plant, whereas PI is a two loop plant. Due to only having two loops, PI cannot justify having both SG PORVs inoperable for up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

PART G PACKAGE 3.7 PLANT SYSTEMS NO SIGNIFICANT HAZARDS DETERMINATION AND ENVIRONMENTAL ASSESSMENT NO SIGNIFICANT HAZARDS DETERMINATION The proposed changes to the Operating License have been evaluated to determine whether they constitute a significant hazards consideration as required by 1 OCFR Part 50, Section 50.91 using the standards provided in Section 50.92.

For ease of review, the changes are evaluated in groupings according to the type of change involved. A single generic evaluation may suffice for some of the changes while others may require specific evaluation in which case the appropriate reference change numbers are provided.

A - Administrative (GENERIC NSHD)

(A3.7-00, A3.7-01, A3.7-02, A3.7-04, A3.7-05, A3.7-06, A3.7-09, A3.7-20, A3.7-21, A3.7-34, A3.7-36, A3.7-44, A3.7-45, A3.7-47, A3.7-57, A3.7-62, A3.7-66, A3.7-74, A3.7 77, A3.7-78, A3.7-83, A3.7-94, A3.7-97, A3.7-105, A3.7-113)

Most administrative changes have not been marked-up in the Current Technical Specifications, and may not be specifically referenced to a discussion of change. This No Significant Hazards Determination (NSHD) may be referenced in a discussion of change by the prefix "A" if the change is not obviously an administrative change and requires an explanation.

These proposed changes are editorial in nature. They involve reformatting, renaming, renumbering, or rewording of existing Technical Specifications to provide consistency with NUREG-1431 or conformance with the Writer's Guide, or change of current plant terminology to conform to NUREG-1431. Some administrative changes involve relocation of requirements within the Technical Specifications without affecting their technical content. Clarifications within the new Prairie Island Improved Technical Specifications which do not impose new requirements on plant operation are also considered administrative.

This proposed Technical Specifications revision involves modifying the Current Technical Specifications to impose more stringent requirements upon plant operations to achieve consistency with the guidance of NUREG-1431, correct discrepancies or remove ambiguities from the specifications. These more restrictive Technical Specifications have been evaluated against the plant design, safety analyses, and other Technical Specifications requirements to ensure the plant will continue to operate safely with these more stringent specifications.

1. The proposed amendment will not involve a significant increase in the probability or consequences of an accident previously evaluated.

The proposed changes provide more stringent requirements for operation of the plant. These more stringent requirements do not result in operation that will increase the probability of initiating an analyzed event and do not alter assumptions relative to mitigation of an accident or transient event.

These more restrictive requirements continue to ensure process variables, structures, systems, and components are maintained consistent with the safety analyses and licensing basis. Therefore, these changes do not involve a significant increase in the probability or consequences of an accident previously evaluated.

2.

The proposed amendment will not create the possibility of a new or different kind of accident from any accident previously analyzed.

The proposed changes do not involve a physical alteration of the plant, that is, no new or different type of equipment will be installed, nor do they change the methods governing normal plant operation.

These more stringent requirements do impose different operating restrictions.

However, these operating restrictions are consistent with the boundaries established by the assumptions made in the plant safety analyses and licensing bases. Therefore, these changes do not create the possibility of a new or different kind of accident from any accident previously evaluated.

Part G Package 3.7 R - Relocation (GENERIC NSHD)

(R3.7-32, R3.7-69, R3.7-79, R3.7-81, R3.7-106)

This License Amendment Request (LAR) proposes to relocate requirements contained in the Current Technical Specifications out of the Technical Specifications into licensee controlled programs. These requirements are relocated because they 1) do not meet the Technical Specifications selection criteria defined in 10 CFR 50.36; or 2) are mandated by current Nuclear Regulatory Commission (NRC) regulations and are therefore unnecessary in the Technical Specifications.

In the NRC Final Policy Statement on Technical Specifications Improvements for Nuclear Power Reactors (dated 7/16/93), the NRC stated:

.. since 1969, there has been a trend towards including in Technical Specifications not only those requirements derived from the analyses and evaluations included in the safety analysis report but also essentially all other Commission requirements governing the operation of nuclear power reactors....

This has contributed to the volume of Technical Specifications and to the several fold increase, since 1969, in the number of license amendment applications to effect changes to the Technical Specifications. It has diverted both staff and licensee attention from the more important requirements in these documents to the extent that it has resulted in an adverse but unquantifiable impact on safety.

Thus, relocation of unnecessary requirements from the Current Technical Specifications should result in an overall improvement in plant safety through more focused attention to the requirements that are most important to plant safety.

1.

The proposed amendment will not involve a significant increase in the probability or consequences of an accident previously evaluated.

These proposed changes relocate requirements for structures, systems, components or variables which did not meet the criteria for inclusion in the improved Technical Specifications, or which duplicate regulatory requirements. The affected structures, systems, components or variables are not assumed to be initiators of analyzed events and are not assumed to mitigate accident or transient events.

Part G Package 3.7 LR - Less restrictive, Relocated details (GENERIC NSHD)

(LR3.7-17, LR3.7-18, LR3.7-19, LR3.7-24, LR3.7-28, LR3.7-29, LR3.7-38, LR3.7-41, LR3.7-43, LR3.7-63, LR3.7-64, LR3.7-67, LR3.7-68, LR3.7-82, LR3.7-84, LR3.7-86, LR3.7-87, LR3.7-98, LR3.7-99, LR3.7-100, LR3.7-102, LR3.7-112)

Some information in the Prairie Island Current Technical Specifications that is descriptive in nature regarding the equipment, system(s), actions or surveillances identified by the specification has been removed from the proposed specification and relocated to the proposed Bases, Updated Safety Analysis Report or licensee controlled procedures. The relocation of this descriptive information to the Bases of the Improved Technical Specifications, Updated Safety Analysis Report or licensee controlled procedures is acceptable because these documents will be controlled by the Improved Technical Specifications required programs, procedures or 10CFR50.59. Therefore, the descriptive information that has been moved continues to be maintained in an appropriately controlled manner.

1.

The proposed amendment will not involve a significant increase in the probability or consequences of an accident previously evaluated.

The proposed changes relocate detailed, descriptive requirements from the Technical Specifications to the Bases, Updated Safety Analysis Report or licensee controlled procedures. These documents containing the relocated requirements will be maintained under the provisions of IOCFR50.59, a program or procedure based on 1 OCFR50.59 evaluation of changes, or NRC approved methodologies. Since these documents to which the Technical Specifications requirements have been relocated are evaluated under 10CFR50.59 or its guidance, or in accordance with NRC approved methodologies, no increase in the probability or consequences of an accident previously evaluated will be allowed without prior NRC approval.

Therefore, these changes do not involve a significant increase in the probability or consequences of an accident previously evaluated.

Part G Package 3.7 L - Less restrictive, Specific Each CTS change which is designated as Less (L prefix) restrictive on plant operations is provided with a specific NSHD.

Specific NSHD for Change L3.7-03 CTS does not provide an action statement addressing inoperability of one or more MSSVs; therefore the unit would be required to enter CTS 3.0.0 if a MSSV were inoperable. CTS 3.0.C allows 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> to implement corrective action whereas this change proposes to allow four hours to implement corrective action. This change is acceptable because the probability is very low that a pressure transient will occur during this additional three hours; the SG PORVs will initially address a main steam pressure transient so the probability the MSSVs will be required to operate during this additional three hours is even lower. Furthermore, there are four other MSSVs, which service the SG being affected, which further reduces the likelihood that any particular MSSV will be required at any time. This change is consistent with the approved GITS.

1.

The proposed amendment will not involve a significant increase in the probability or consequences of an accident previously evaluated.

The proposed change involves extending the time allowed for one MSSV to be inoperable while corrective actions are implemented. Since MSSV design or Function has not changed, this change does not affect the probability of an accident. There are other system design features, such as the SG PORVs, which provide for pressure transient protection. In addition, the probability of an event, which requires any particular MSSV to operate is very low. Therefore this change does not involve a significant increase in the probability or consequences of an accident.

2.

The proposed amendment will not create the possibility of a new or different kind of accident from any accident previously analyzed.

The proposed change does not involve a physical alteration of the plant (no new or different type of equipment will be installed) or changes in parameters governing normal plant operation. Thus, this change does not create the possibility of a new or different kind of accident.

Part G Package 3.7 Specific NSHD for Change L3.7-03 (continued)

3.

The proposed amendment will not involve a significant reduction in the margin of safety.

The proposed change in effect extends the time for a MSSV to be inoperable while corrective actions are implemented from one hour to four hours. The probability of a plant transient during the three additional hours, which would require the inoperable MSSV to operate, is very low. The additional three hours allows the plant to attempt to make repairs and prepare for a well, planned shutdown. The process of shutting down the plant is more likely to cause a transient requiring the MSSVs than continued plant operation. Furthermore, there are other plant design features, such as the SG PORVs and Steam Dumps, to mitigate steam line pressure transients. Thus, this change does not involve a significant reduction in the margin of safety.

Therefore it is concluded this proposed change does not involve a significant hazards consideration.

Part G Package 3.7 Specific NSHD for Change L3.7-07 CTS allow one SG PORV to be inoperable for 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />. Since there are other means available to provide a heat sink for the SGs, it is acceptable to extend this outage time to 7 days. This change would also allow both SG PORVs to be inoperable for 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />.

This change is consistent with the guidance of NUREG-1431.

1.

The proposed amendment will not involve a significant increase in the probability or consequences of an accident previously evaluated.

The proposed change involves extending the time allowed for one SG PORV to be inoperable and defines allowable outage time for both SG PORVs inoperable. Since the SG PORV design or Function has not changed, these changes do not affect the probability of an accident. There are other systems which provide a comparable SG heat sink such as the Steam Dumps to the condenser, Steam Dumps to the atmosphere and the Main Steam Safety Valves. Thus the unavailability of one SG PORV for up to 7 days or both SG PORVs up to 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> does not involve a significant increase in the consequences of an accident. Also the probability of an event requiring use of a SG PORV during these allowed outage times is low.

2.

The proposed amendment will not create the possibility of a new or different kind of accident from any accident previously analyzed.

The proposed change makes the PI ITS consistent with the guidance of NUREG 1431 and does not involve a physical alteration of the plant (no new or different type of equipment will be installed) or changes in parameters governing normal plant operation. Thus, this change does not create the possibility of a new or different kind of accident.

Part G Package 3.7 Specific NSHD for Change L3.7-114 This change allows separate Condition entry when both MSIVs are inoperable while in Mode 2 or 3. This change is acceptable since the Required Actions assure that the safety function of the MSIVs continue to meet the PI safety analysis. This change is consistent with the guidance of NUREG-1431.

1.

The proposed amendment will not involve a significant increase in the probability or consequences of an accident previously evaluated.

This change will allow separate Condition entry for the MSIVs when the plant is in Mode 2 or 3. The Required Action require that an inoperable MSIV be closed within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> and verified closed once per 7 days. When in the closed position, the MSIV is performing its intended safety function. Since the MSIVs are not design basis accident initiators, this change does not involve an increase in the probability of an accident. Therefore, this change does not involve a significant increase in the consequences of an accident previously evaluated.

Since the Required Action requires the MSIV to be closed, it will be performing its intended safety function. Therefore, this proposed change does not involve a significant increase in the consequences of an accident previously evaluated.

2.

The proposed amendment will not create the possibility of a new or different kind of accident from any accident previously analyzed.

The proposed change does not involve a physical alteration of the plant (i.e., no new or different type of equipment will be installed). The proposed change introduces no new mode of plant operation or changes in the methods governing normal plant operation. Thus, this change does not create the possibility of a new or different kind of accident from any accident previously evaluated.

Part G Package 3.7 Specific NSHD for Change L3.7-114 (continued)

3.

The proposed amendment will not involve a significant reduction in the margin of safety.

The proposed change allows the plant to continue operating in Modes 2 or 3 with an inoperability in both MSIVs in conformance with the guidance of NUREG-1431.

Since a condition is not defined in the CTS for simultaneous inoperabilities of both MSIVs in these Modes, the plant would be required to enter LCO 3.0.C and shut down. Required Action C allows a MSIV to be closed in 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> and verified closed once per 7 days. Since the MSIV would be closed, it would be performing its intended safety function. Therefore this change does not involve a significant reduction in the margin of safety.

Therefore it is concluded this proposed change does not involve a significant hazards consideration.

Part G Package 3.7 Specific NSHD for Change L3.7-117 CTS 3.3.C.1 (b) requires that during STARTUP OPERATION or POWER OPERATION, "any one of" the following conditions of inoperability may exist provided startup operation is discontinued until OPERABILITY is restored. If OPERABILITY is not restored within the time specified, be in at least HOT SHUTDOWN within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in COLD SHUTDOWN within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.

(1) One of the assigned component cooling pumps may be inoperable for 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.

(2) One of the assigned component cooling heat exchangers may be inoperable for 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.

The CTS does not allow a component cooling pump and a cooling heat exchanger to be inoperable at the same time. The ITS allow an entire train to be inoperable for 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. A train in this case is the component cooling pump and component cooling heat exchanger. Allowing both to be inoperable makes this a less restrictive change.

1.

The proposed amendment will not involve a significant increase in the probability or consequences of an accident previously evaluated.

This change eliminates the CTS requirement of having either a component cooling (CC) pump or CC heat exchanger inoperable at the same time whereas, the ITS allows having an entire CC train inoperable. The CC train, in the ITS, includes both the CC pump and CC heat exchanger. PI design is that the CC pumps are interconnected so that either pump from either unit can be manually aligned to serve any heat exchanger, and the capability of manually switching the pumps enables the two unit system to tolerate loss of an additional pump with one pump already out of service. The heat exchangers are not similarly interconnected, so loss or outage of a heat exchanger disables one set of essential equipment in one unit. Therefore, the ITS allowing a train to be inoperable allows either a CC pump or CC heat exchanger to be inoperable or both can be inoperable. Once the CC heat exchanger is lost, the entire train would be inoperable and therefore, requiring entry into Condition A. PI has been analyzed for the event where a failure disables an entire loop consisting a pump and heat exchanger, in the same train. In this case, the plant would have sufficient CC cooling to successfully and safely shut down the unit. For a LOCA, PI safety analysis shows that one CC pump and CC heat exchanger can accommodate the heat removal loads. Therefore, redefining the CTS requirements of allowing a CC train to be inoperable does not involve a significant increase in the consequences of an accident previously evaluated.

Since the CC system is not an assumed accident initiator in the PI USAR Safety Analysis, there is not a significant increase in the probability of an accident previously evaluated.

Part G Package 3.7 Specific NSHD for Change L3.7-117 (continued)

2.

The proposed amendment will not create the possibility of a new or different kind of accident from any accident previously analyzed.

The proposed change does not involve a physical alteration of the plant (i.e., no new or different type of equipment will be installed). The proposed change introduces no new mode of plant operation or changes in the methods governing normal plant operation. Thus, this change does not create the possibility of a new or different kind of accident from any accident previously evaluated.

3.

The proposed amendment will not involve a significant reduction in the margin of safety.

Allowing a CC train to be inoperable as allowed by the ITS supports PI safety analysis. PI is analyzed for losing a loop of CC during a LOCA and still ensuring plant safe shutdown as discussed in USAR 10.4.2.3. Therefore, the CTS change is consistent with NUREG-1431 and PI accident analysis. Therefore this change does not involve a significant reduction in the margin of safety.

Part G Package 3.7 Specific NSHD for Change L3.7-118 The proposed change would allow the control room boundary to be open with both trains of the CRSVS inoperable under administrative controls for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> while the unit is in MODES 1, 2, 3, or 4. The CTS does not allow this flexibility.

1.

The proposed amendment will not involve a significant increase in the probability or consequences of an accident previously evaluated.

This proposed change would allow the control room boundary to be opened with both trains of CRSVS inoperable for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> under administrative controls.

Requiring the plant to enter LCO 3.0.3 when the ventilation envelope is not intact is excessive and not appropriate. If the control room boundary is inoperable in MODES 1, 2, 3, and 4, the CRSVS trains cannot perform their intended functions.

Actions must be taken to restore an OPERABLE control room boundary within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. Preplanned measures would be available to address these concerns for intentional and unintentional entry into the condition. The 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> 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 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> Completion Times is a typically reasonable time to diagnose, plan, and possibly repair, and test most problems with the control room boundary. Accident consequences are not significantly increased because any opening in the control room envelope (under this Specification) is under direct administrative controls, thus, the control room boundary integrity can be restored in the event of a DBA. This proposed change can only be applied to those areas where administrative control will not be precluded by the initiating event itself. For example, administrative control cannot be credited for an open door (required for steam exclusion) if the person(s) controlling the door would be precluded from restoring the control room boundary by a main steam line break. Therefore, allowing the control room boundary to be open with both trains of CRSVS to be inoperable for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> under administrative controls does not involve a significant increase in the consequences of an accident previously evaluated.

2.

The proposed amendment will not create the possibility of a new or different kind of accident from any accident previously analyzed.

The proposed change does not involve a physical alteration of the plant (i.e., no new or different type of equipment will be installed). The proposed change introduces no new mode of plant operation or changes in the methods governing normal plant operation. Thus, this change does not create the possibility of a new or different kind of accident from any accident previously evaluated.

3.

The proposed amendment will not involve a significant reduction in the margin of safety.

Allowing both CRSVS trains to be inoperable for up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> under administrative controls is acceptable. During this time, entry and exit of plant personnel would be allowed. In addition, appropriate compensatory measures will be utilized to protect the control room operators from potential hazards such as radioactive contamination, toxic chemicals, smoke, temperature and relative humidity, and physical security. During this proposed time, control room integrity can be restored as needed. This proposed change can only be applied to those areas where administrative control will not be precluded by the DBA itself. The 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> Completion Time is reasonable based on the low probability of a DBA occurring during this time period in addition to the use of other compensatory measures. This change does not significantly reduce the margin of safety because it provides an equivalent level of CRSVS protection to the control room, such that the control room operators are not prevented from maintaining the integrity of fuel cladding, the reactor coolant system, or the containment. Based on the above, this change does not involve a significant reduction in the margin of safety.

Therefore it is concluded this proposed change does not involve a significant hazards consideration.

Prairie Island Units 1 and 2 52 2/2/02

Part G ENVIRONMENTAL ASSESSMENT Package 3.7 The Nuclear Management Company has evaluated the proposed changes and determined that:

1. The changes do not involve a significant hazards consideration, or
2.

The changes do not involve a significant change in the types or significant increase in the amounts of any effluents that may be released offsite, or

3.

The changes do not involve a significant increase in individual or cumulative occupational radiation exposure.

Accordingly, the proposed changes meet the eligibility criteria for categorical exclusion set forth in 10 CFR Part 51 Section 51.22(c)(9). Therefore, pursuant to 10 CFR Part 51 Section 51.22(b), an environmental assessment of the proposed changes is not required.

Diesel Fuel Oil B 3.8.3 BASES ACTIONS D. 1 (continued)

With the stored fuel oil supply not within the limits specified or Required Actions and associated Completion Times of Conditions A or C not met, the DGs may be incapable of performing their intended function and must be immediately declared inoperable.

A Note has been added to Condition D requiring entry into the applicable Conditions and Required Actions of LCO 3.7.8, "CL System" when Condition D is entered as a result of stored fuel oil properties not within limits. Since the diesel generators and the diesel driven CL pumps share a common storage tank, the diesel fuel oil properties are maintained by Specification 5.5.11, "Diesel Fuel Oil Testing Program." Therefore, if the fuel oil properties are not within limits, both the diesel generators and the diesel driven CL pumps are affected and appropriate Required Actions taken.

SURVEILLANCE SR 3.8.3.1 REQUIREMENTS This SR provides verification that there is an adequate inventory of fuel oil in the storage tanks to support the operation of one DG for 14 days. The 14 day period is sufficient time to place the unit in a safe shutdown condition and to bring in replenishment fuel from an offsite location.

The specified fuel oil inventory for the Unit 1 emergency diesel generators (EDGs) is in addition to the fuel oil inventory specified for the diesel driven cooling water pumps (LCO 3.7.8) that must be available in the Unit 1 diesel fuel oil storage system. There are four Design Class I fuel oil storage tanks for the Unit 1 EDGs and two Design Class I fuel oil storage tanks for the diesel driven cooling water pumps. These six Design Class I tanks are interconnected such that any tank can be manually aligned to supply any Unit 1 Prairie Island Units 1 and 2 B 3.8.3-4 2/2/02

REQUREMENTS EDG or diesel driven cooling water pump day tank. Any combination of inventory in these six tanks may be used to satisfy the inventory requirements for the Unit 1 EDGs and the diesel driven cooling water pumps. There are four Unit 2 Design Class I fuel oil storage tanks. The four Unit 2 tanks are interconnected such that any tank can be manually aligned to supply either Unit 2 EDG day tank. Any combination of inventory in these four Unit 2 tanks may be used to satisfy the Unit 2 EDG inventory requirements.

The 31 day Frequency is adequate to ensure that a sufficient supply of fuel oil is available, since low level alarms are provided and unit operators would be aware of any large uses of fuel oil during this period.

SR 3.8.3.2 The tests for the new fuel oil prior to addition into the safeguards storage tank(s) are a means of determining whether new fuel oil is of the appropriate grade and has not been contaminated with substances that would have an immediate, detrimental impact on diesel engine combustion. If results from these tests are within acceptable limits, the fuel oil may be added to the safeguards storage tanks without concern for contaminating the entire volume of fuel oil in the safeguards storage tanks. These tests are to be conducted prior to adding the new fuel to the safeguards storage tank(s), but in no case is the time between receipt of new fuel and conducting the tests to exceed 31 days. The tests and limits for new and stored fuel are described in the Diesel Fuel Oil Testing Program of Specification 5.5.11.

68 New Note. A new Note has been added to NUREG-1431, LCO 3.8.3 Condition D requiring that if the diesel fuel oil cannot be restored to within limits, declare the DGs inoperable and "enter applicable Conditions and Required Actions of LCO 3.7.8, "CL System" when Condition D is entered as a result of stored fuel oil properties not within limits." The PI design for the DGs and diesel driven CL pumps is a shared common fuel oil storage tank. The contents of the tank are controlled under ITS 5.5.11, "Diesel Fuel Oil Testing Program." In the event that the subject fuel oil properties are not within limits, ITS 3.8.3 provides specific Required Actions to restore the fuel oil to within limits or declare the DGs inoperable immediately.

There are no separate Required Actions for the diesel driven CL pumps. If the fuel oil in the storage tanks is not within limits for the DGs, it is also not within limits for the diesel driven CL pumps. Providing this Note in the ITS maintains CTS and provides assurance that the quality of the fuel oil for the diesel driven CL pumps is maintained to within standards and ensuring the pumps remain OPERABLE. Since this change maintains CTS, this is considered an Administrative change.

Difference Difference Category Number Justification for Differences 3.8 PA 218 NUREG-1431 LCO 3.8.3, Required Action D, has been revised by a Note stating, "Enter applicable Conditions and Required Actions of LCO 3.7.8, 'CL System' when Condition D is entered as a result of stored fuel oil properties not within limits". The requirements for diesel fuel oil volume have been divided into two separate specifications. ITS 3.7.8 provides diesel fuel oil volume for the diesel driven CL pumps and ITS 3.8.3 provides the requirements for the diesel generators. In addition, ITS 5.5.11 provides the requirements for the Diesel Fuel Oil Testing Program. Both the diesel driven CL pumps and the plant diesel generators share a common storage tank and fuel oil contents. ITS 3.8.3 provides requirements for testing the tank contents and associated Required Actions if the fuel oil properties are not restored to within limits. A Note was added to Condition D instructing the operators that if the diesel fuel oil in the storage tanks is not within limits, to enter the associated Conditions and Required Actions for the diesel driven CL pumps. This change provides consistency between the two systems and is consistent with current plant design and practices.

Part G PACKAGE 3.8 ELECTRICAL POWER SYSTEMS NO SIGNIFICANT HAZARDS DETERMINATION AND ENVIRONMENTAL ASSESSMENT NO SIGNIFICANT HAZARDS DETERMINATION The proposed changes to the Operating License have been evaluated to determine whether they constitute a significant hazards consideration as required by 1 OCFR Part 50, Section 50.91 using the standards provided in Section 50.92.

For ease of review, the changes are evaluated in groupings according to the type of change involved. A single generic evaluation may suffice for some of the changes while others may require specific evaluation in which case the appropriate reference change numbers are provided.

A - Administrative (GENERIC NSHD)

(A3.8-01, A3.8-10, A3.8-13, A3.8-15, A3.8-17, A3.8-20, A3.8-22, A3.8-23, A3.8-25, A3.8-30, A3.8-38, A3.8-39, A3.8-40, A3.8-51, A3.8-53, A3.8-56, A3.8-57, A3.8-58, A3.8-60, A3.8-62 and A3.8-63, A3.8-68)

Most administrative changes have not been marked-up in the CTS, and may not be specifically referenced to a discussion of change (DOC). This NSHD may be referenced in a discussion of change by the suffix "A" if the change is not obviously an administrative change and requires an explanation.

These proposed changes are editorial in nature. They involve reformatting, renaming, renumbering, or rewording of existing TS to provide consistency with NUREG-1431 or conformance with the Writer's Guide, change of current plant terminology to conform to NUREG-1431 or change of NUREG-1431 terminology to conform to CTS. Some administrative changes involve relocation of requirements within the TS without affecting their technical content. Clarifications within the NEW PI ITS which do not impose new requirements on plant operation are also considered administrative.
