p h p?re q uestT ype=areaItemPrint&itemId=301 DISCUSSION OF CHANGES ITS 3.3.1, REACTOR PROTECTION SYSTEM (RPS) INSTRUMENTATION Kewaunee Power Station Page 2 of 31 A03 CTS Table TS 3.5-2, Column 3 specifies the "MINIMUM OPERABLE CHANNELS" associated with each RPS Functional Unit and CTS 3.5.2 specifies the actions to take when the number of channels for a particular Functional Unit is less than the Column 3 requirements. Additionally, the Notes for Table

TS 3.5-2 contain a table that pertains to the RPS Permissives and Interlocks.

This Note table contains a column titles "Coincident," which describes the coincidence logic needed for each permissive/interlock. ITS LCO 3.3.1 requires the RPS Instrumentation to be OPERABLE, and includes only one column in Table 3.3.1-1 titled "REQUIRED CHANNELS." This changes the CTS by changing the title of the MINIMUM OPERABLE CHANNELS" and "Coincidence" columns to "REQUIRED CHANNELS."

This change is acceptable because the ITS Table 3.3.1-1 "REQUIRED CHANNELS" column reflects the requirements for when actions are required to be taken, consistent with the CTS Table TS 3.5-2 column when actions must be taken. In addition, the change is acceptable for the RPS Permissives and Interlocks Note table since the description of the coincidence logic that is required (e.g., 1 of 2 for P-6) implies that all the Permissives and Interlock channels are required. This change is designated as administrative because it does not result in technical changes to the CTS.

A04 CTS Table TS 3.5-2 Column 6 specifies the "OPERATOR ACTION IF CONDITIONS OF COLUMN 3 OR 4 CANNOT BE MET." CTS Table TS 3.5-2 Column 6 requires maintaining HOT SHUTDOWN for Functional Units 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 13, 14, 16, and 17. Based on the CTS Table TS 3.5-2 requirement to maintain HOT SHUTDOWN, the Mode of Applicability would be considered OPERATING and HOT STANDBY for Functional Units 1(Manual), 2, (Nuclear Flux Power Range (High Setting, Positive Setting, and Negative Setting)), 5 (Overte Pressure), 12 (Lo-Lo Steam Generator Water Level), 16 (Steam Flow/Feedwater Flow Mismatch), and 17 (Reactor Trip Breaker (RTB) and (Independently Test Shunt and Undervoltage Trip Attachments). For Functional Unit 2 (Nuclear Flux Power Range (Low Setting)), the Mode of Applicability is OPERATING below the P-10 interlock and HOT STANDBY for the Nuclear Flux Power Range (Low Setting) because Column 5 of Table TS 3.5-2 lists the permissible bypass condition as P-10. This means that the Nuclear Flux Power Range (Low Setting) channels are blocked above the P-10 setting. With the P-10 Setting Limit of

< 7.8% RATED POWER, Nuclear Flux Power Range (Low Setting) would be required to be OPERABLE in the OPERATING MODE below the P-10 limit and in HOT STANDBY. For Functional Unit 3 (Nuclear Flux Intermediate Range), the MODE of Applicability is OPERATING below the P-10 interlock and HOT STANDBY because Column 5 of Table TS 3.5-2 lists the permissible bypass condition as P-10. This means that the Nuclear Flux Intermediate Range channels are blocked above the P-10 setting. With the P-10 Setting Limit of < 7.8% RATED POWER, Nuclear Flux Intermediate Range would be required to be OPERABLE in the OPERATING MODE below the P-10 limit. Furthermore, since the Nuclear Flux Intermediate Range are not required until below the P-6 setting, then the HOT STANDBY requirement would only be above the P-6

setting. Therefore, the MODE of Applicability, for the Nuclear Flux Intermediate Range, would be OPERATING below the P-10 interlock and HOT STANDBY above the P-6 interlock.

As shown on CTS Table TS 3.5-2 (Attachment 1, Volu me 8, Page 7 of 517)

Functional Unit 10 is Low Flow in One Loop and Low Flow Both Loops. Therefore, the sentence on Attachment 1, Volume 8, Page 22 of 517, in Discussion of Change A04 is proposed to be changed to state "For Functional Unit 10 (Low Flow in One Loop and Low Flow Both Loops), the Mode of Applicability is OPERATING because Column 5 lists the permissible bypass conditions for Low Flow in One Lo op as P-8 and for Low Flow in Two Loops as P-7." A draft markup rega rding this change is attached. This change will be reflected in the suppl ement to this section of the ITS conversion amendment.

p h p?re q uestT ype=areaItemPrint&itemId=311 DISCUSSION OF CHANGES ITS 3.3.1, REACTOR PROTECTION SYSTEM (RPS) INSTRUMENTATION Kewaunee Power Station Page 3 of 31 Mode of Applicability is HOT STANDBY because Column 5 of Table TS 3.5-2 lists the permissible bypass condition as P-6. This means that the Nuclear Source Range channels are blocked when above the P-6 setting. With the P-6

Setting Limit of > 10

-5% RATED POWER, the Nuclear Source Range would not be required to be OPERABLE above HOT STANDBY. For Functional Unit 7 (Low Pressurizer Pressure), 9 (Pressurizer High Water Level), 13 (Undervoltage 4-kV), and 14 (Underfrequency 4-kV), the Mode of Applicability is OPERATING because Column 5 of Table TS 3.5-2 lists the permissible bypass condition as P-7. This means that the Low Pressurizer Pressure channel, the Pressurizer

High Water Level, the Undervoltage 4-kV, and the Underfrequency 4-kV channels are blocked when below the P-7 setting. With the P-7 Setting Limit of > 12.2% RATED POWER, the Low Pressurizer Pressure, the Pressurizer High Water Level, the Undervoltage 4-kV, and the Underfrequency 4-kV would not be required to be OPERABLE below the OPERATING MODE. For Functional Unit

10 (Low Flow in One Loop) and (Low Flow in One Loop), the Mode of

Applicability is OPERATING because Column 5 lists the permissible bypass condition for Low Flow in One Loop as P-8 and for Low Flow in Two Loops as P-7. For the Low Flow in One Loop, this means that the channels are blocked

when below the P-8 setting. With the P-8 Setting Limit of < 10% RATED POWER, Low Flow in One Loop channel would not be required to be

OPERABLE below the OPERATING MODE. For the Low Flow in Two Loops, this means that the channels are blocked when below the P-7 setting. With the P-7 Setting Limit of > 12.2% RATED POWER, the channel would not be required to be OPERABLE below the OPERATING MODE. ITS LCO 3.3.1 requires the

RPS instrumentation in Table 3.3.1-1 to be OPERABLE. ITS Table 3.3.1-1 Function 1, 2.a, 2.b, 3.a, 3.b, 4, 6, 7, 8.b, 14, 15, 17, and 18 state that the APPLICABLE MODE OR OTHER SPECIFIED CONDITIONS is MODE 1 and 2.

ITS Table 3.3.1-1 Function 2.b (Power Range Neutron Flux - Low) states that the APPLICABLE MODE OR OTHER SPECIFIED CONDITIONS is MODE 1

below the P-10 (Power Range Neutron Flux) interlock and MODE 2. ITS Table 3.3.1-1 Function 4 states that the APPLICABLE MODE OR OTHER SPECIFIED

CONDITIONS is MODE 1 below the P-10 (Power Range Neutron Flux) and MODE 2 above the P-6 (Intermediate Range Neutron Flux) Interlocks. ITS Table 3.3.1-1 Function 5 (Source Range Neutron Flux) state that the APPLICABLE MODE OR OTHER SPECIFIED CONDITIONS is MODE 2 below the P-6 (Intermediate Range Neutron Flux) interlocks. ITS Table 3.3.1-1 Function 8.a, 9, 12, and 13 state that the APPLICABLE MODE OR OTHER SPECIFIED CONDITIONS is MODE 1 above the P-7 (Low Power Reactor Trip Block) interlock. ITS Table 3.3.1-1 Function 10 states that the APPLICABLE MODE OR OTHER SPECIFIED CONDITIONS is MODE 1 above the P-8 (Power Range Neutron Flux) interlock. This changes the CTS by explicitly stating the MODES of Applicability for each Functional Unit.

This change is acceptable because the requirements are the same. The ITS explicitly states the MODES of Applicability in ITS Table 3.3.1-1. This change is designated as administrative because it does not result in technical changes to

the CTS.

A05 CTS Table 3.5-2 includes Channels, Coincidence, and setting limits for P-6, P-7, P-8, P-10, and P-13. However, no specific Applicability requirements are provided.

This changes the CTS by adding specific applicable MODES or other specified conditions associated with P-6, P-7, P-8, P-10, and P-13 interlocks.

This change is acceptable because the change provides more explicit conditions for when the interlocks are required to be OPERABLE, and is consistent with the RPS Functions they support (i.e., the RPS instruments described in the Functional Unit column of CTS Table 3.5-2). This change is designated as administrative because it does not result in a technical change to the CTS.

A06 CTS 4.1.a requires calibration, testing, and checking of protective instrumentation channels and testing of logic channels shall be performed as specified in Table TS 4.1-1. Table TS 4.1-1 requires performance of a TEST at the frequencies shown on Table TS 4.1-1. CTS 4.1.b requires, in part, equipment tests shall be conducted as specified in Table TS 4.1-3. Table TS 4.1-3 requires performance of a TEST at the frequencies shown on Table TS 4.1-3. Table TS 4.1-1 requires performance of a TEST at the frequencies

shown on Table TS 4.1-1. ITS 3.3.1 requires the performance of either a CHANNEL OPERATIONAL TEST (COT), a TRIP ACTUATING DEVICE OPERATIONAL TEST (TADOT), or, in the case of the Automatic Trip Logic, an ACTUATION LOGIC TEST. This changes the CTS by changing the TEST requirements to a COT, a TADOT, or an ACTUATION LOGIC TEST.

This change is acceptable because the COT, a TADOT, or an ACTUATION LOGIC TEST continue to perform tests similar to the current TEST. This change is one of format only and any technical change to the requirements is specifically addressed in an individual Discussion of Change. This change is designated as administrative because it does not result in technical changes to the CTS.

A07 Note (a) to CTS Table TS 4.1-1, Channel Description 2 and 3 in the Remarks Section states that Channel Check is once per shift when in service. For ITS Table 3.3.1-1 Function 4 and 5, ITS SR 3.3.1.1, the equivalent CHANNEL CHECK requirement, has a frequency of 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months . This changes the CTS by deleting this specific Note.

While the purpose of the Note appears to require the Channel Check only when it is in service, CTS 4.0.a, which provides the general requirements of all Surveillance Requirements, specifically states that Surveillances are only required to be met during the operational MODES or other specified conditions in the LCO. ITS SR 3.0.1 provides the same general requirement for Surveillances.

Therefore, it is unnecessary to reiterate that a CHANNEL CHECK is required when the instrument is in service. Therefore, the deletion of this Note is acceptable and considered administrative, since the technical requirements have not been changed.

A08 Note (c) to CTS Table TS 4.1-1, Channel Description 2 and 3 in the Remarks Section states that the Channel Check is required in all plant modes. For ITS Table 3.3.1-1 Function 4, ITS SR 3.3.1.1, the equivalent CHANNEL CHECK requirement, is only applicable in MODE 1 above the P-10 (Power Range Neutron Flux) interlocks and in MODE 2 below the P-6 (Intermediate Range A ttachment 1, Volume 8, Rev. 0, Page 23 of 517 A ttachment 1, Volume 8, Rev. 0, Page 23 of 517 Enclosure (1 of 8), Q&A to Attachment 1, Volume 8 (Section 3.3) Page 15 of 41 Enclosure (1 of 8), Q&A to Attachment 1, Volume 8 (Section 3.3) Page 15 of 41 below above Licensee Response/NRC Response/NRC Question Closure Id621NRC Question Number KAB-004 Select Application NRC Question Closure Response Date/Time Closure Statement This question is closed and no further information is required at this time to draft the Safety Evaluation.

Table TS 3.5-2 Functional Unit 1 (Manual Reactor Trip) Column 6 requires maintaining HOT SHUTDOWN. Table TS 3.5-2 Functional Unit 1 (Manual Reactor Trip)

Column 6 requires, in part, maintaining HOT SHUTDOWN. Thus, the applicability for these Functional Units is determined to be HOT STANDBY and OPERATING. ITS LCO 3.3.1 requires the RPS instrumentation in Table 3.3.1-1 to be OPERABLE. ITS Table 3.3.1-1 Function 1 specifies the Applicability of the Manual Reactor Trip as MODES 1 and 2 (equivalent to CTS OPERATING and

HOT STANDBY, respectively); and MODES 3, 4, and 5 (equivalent to CTS HOT SHUTDOWN, INTERMEDIATE SHUTDOWN and COLD SHUTDOWN, respectively) when the Rod Control System is capable of rod withdrawal or when one or more rods are not fully inserted. ITS Table 3.3.1-1 Function 1 specifies the Applicability of the Reactor Trip Breakers (RTBs) trains to be MODES 3, 4, and 5 when the Rod Control System is capable of rod withdrawal or when one or

more rods are not fully inserted, in addition to MODES 1 and 2. ITS Table 3.3.1-1 Function 18 requires the Applicability of the Reactor Trip Breaker Undervoltage and Shunt Trip Mechanisms to be MODES 3, 4, and 5 when the Rod Control System is capable of rod withdrawal or when one or more rods are not fully inserted, in addition to MODES 1 and 2. Commensurate with the addition of the new MODES of Applicability, ACTION C was added to address when there is one channel or train inoperable in MODES 3, 4, and 5 when the

Rod Control System is capable of rod withdrawal or when one or more rods are not fully inserted. ACTION C requires that with one channel or train inoperable, to either restore the channel or train to OPERABLE status within 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months or to initiate action to fully insert all rods within 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months and to place the Rod Control System in a condition incapable of rod withdrawal within 49 hours5.671296e-4 days 0.0136 hours 8.101852e-5 weeks 1.86445e-5 months . Additionally, commensurate with the addition of the new MODES of Applicability, new Surveillance Requirements are being adding. ITS SR 3.3.1.14 has been added for Function 1 to perform a TADOT every 18 months, but is modified by a Note that states that the verification of the setpoint is not required. ITS SR 3.3.1.4 has been added for Function 17 and 18 to perform a TADOT every 31 days, but is modified by a Note, which states that the Surveillance must be performed on the reactor trip bypass breaker prior to placing the bypass breaker in service. This changes the CTS by requiring the Manual Reactor Trip channels and the Reactor Trip Breakers (RTBs) trains to be OPERABLE in MODES 3, 4, and 5 when the

Rod Control System is capable of rod withdrawal or when one or more rods are not fully inserted. Furthermore, this change adds an ACTION to take when the Manual Reactor Trip channels and the Reactor Trip Breakers (RTBs) trains are inoperable in MODES 3, 4, and 5 when the Rod Control System is capable of rod withdrawal or when one or more rods are not fully inserted. It also adds additional Surveillance Requirements for the new MODE of Applicability.

This change is acceptable because in MODE 3, 4, or 5 if one or more shutdown rods or control rods are withdrawn or the Rod Control System is capable of withdrawing the shutdown rods or the control rods, there is a possibility of an inadvertent control rod withdrawal. Therefore, action must be taken to restore the channel or train or to place the unit in a condition where there are no withdrawn rods and the ability to withdraw rods is precluded. This change is also acceptable because the new Required Actions and Completion Times are used to establish remedial measures that must be taken in response to the degraded conditions in order to minimize risk associated with continued operation while A ttachment 1, Volume 8, Rev. 0, Page 33 of 517 A ttachment 1, Volume 8, Rev. 0, Page 33 of 517 Enclosure (1 of 8), Q&A to Attachment 1, Volume 8 (Section 3.3) Page 26 of 41 Enclosure (1 of 8), Q&A to Attachment 1, Volume 8 (Section 3.3) Page 26 of 41 17 Licensee Response/NRC Response/NRC Question Closure Id641NRC Question Number KAB-006 Select Application NRC Question Closure Response Date/Time Closure Statement This question is closed and no further information is required at this time to draft the Safety Evaluation.

This changes the CTS by allowing continued operation as long as the interlock is placed in the correct state for existing unit operation and providing actions if the inoperable interlock is not placed in the correct state.

The purpose of the interlocks is to ensure the associated RPS instrumentation is automatically enabled or disabled when required. This change is acceptable since the proposed ACTIONS ensure that the interlock is either manually placed in the correct state for the existing unit conditions or that the unit is placed in a MODE or specified Condition outside the Applicability of the associated interlock. ITS 3.3.1 Required Action P.1 and Q.1 require the interlock to be placed in the same state as it would be normally placed in if it were automatically functioning (i.e., this performs the intended function of the interlock). If the Required Action is not accomplished within 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months , then Required Action P.2 and Q.2 require the unit to be placed in a MODE that is outside of the Applicability of the associated interlock. This change is designated as less restrictive because less stringent Required Actions are being applied in the ITS than were applied in the CTS.

There are two underfrequency relays per bus." In addition, the Kewaunee current Technical Specifications Table TS 3.5-2 functional unit 14 does not list the P-7 interlock under column 5, "permissible bypass cond itions."

5. However, Function Unit 14 is modified by footnote 4, which stat es that Underfre quency on the 4-kV buses trips the Reactor Coolant Pump breakers, which in turn trips the reactor when power is ab ove P-7. Thus, for Functiona l Unit 14, the reactor trip is only required above P-7, and the proposed Appl icability in the ITS is correct. Attached is a simplifi ed diagram of Kewaunee' s underfreque ncy reactor trip logic. Kewaunee h as a trip logic starting with four underfrequency relays two on each of the reactor coolant pump electric supply buses.

From the simplified logic diagram the logic matrix for tripping the reactor coolant pump breakers is 1/2 underfreq uency relays on 2/2 buses (Bus 1 and Bus 2) which then trip both reactor coolant pump breakers. The reactor coolant pump breakers feed a P-8 permissive logic device and a P-7 permissive logic device. The P-8 permissive devi ce is for a single-loop loss of flow condition whereas the P-7 logic device is for a loss of flow in both loops condition. B ecause the underfrequency logic matrix trips both reactor coolant pump breakers the only permissive device of concern for the underfrequency trip is the P-7 permissive.

Thus when the plant is below the P-7 permissive setting an underfrequency condition on Bus 1 and Bus 2 will cause the reactor coolant pumps to trip but a subsequent reactor trip will not occur.

p h p?re q uestT ype=areaItemPrint&itemId=361 DISCUSSION OF CHANGES ITS 3.3.1, REACTOR PROTECTION SYSTEM (RPS) INSTRUMENTATION Kewaunee Power Station Page 14 of 31 according to the requirement shown in Column 6 as soon as practicable. Table TS 3.5-2 Functional Unit 1 (Manual Reactor Trip) Column 6 requires maintaining HOT SHUTDOWN. Table TS 3.5-2 Functional Unit 1 (Manual Reactor Trip)

Column 6 requires, in part, maintaining HOT SHUTDOWN. Thus, the applicability for these Functional Units is determined to be HOT STANDBY and OPERATING. ITS LCO 3.3.1 requires the RPS instrumentation in Table 3.3.1-1 to be OPERABLE. ITS Table 3.3.1-1 Function 1 specifies the Applicability of the Manual Reactor Trip as MODES 1 and 2 (equivalent to CTS OPERATING and

HOT STANDBY, respectively); and MODES 3, 4, and 5 (equivalent to CTS HOT SHUTDOWN, INTERMEDIATE SHUTDOWN and COLD SHUTDOWN, respectively) when the Rod Control System is capable of rod withdrawal or when one or more rods are not fully inserted. ITS Table 3.3.1-1 Function 1 specifies the Applicability of the Reactor Trip Breakers (RTBs) trains to be MODES 3, 4, and 5 when the Rod Control System is capable of rod withdrawal or when one or

more rods are not fully inserted, in addition to MODES 1 and 2. ITS Table 3.3.1-1 Function 18 requires the Applicability of the Reactor Trip Breaker Undervoltage and Shunt Trip Mechanisms to be MODES 3, 4, and 5 when the Rod Control System is capable of rod withdrawal or when one or more rods are not fully inserted, in addition to MODES 1 and 2. Commensurate with the addition of the new MODES of Applicability, ACTION C was added to address when there is one channel or train inoperable in MODES 3, 4, and 5 when the

Rod Control System is capable of rod withdrawal or when one or more rods are not fully inserted. ACTION C requires that with one channel or train inoperable, to either restore the channel or train to OPERABLE status within 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months or to initiate action to fully insert all rods within 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months and to place the Rod Control System in a condition incapable of rod withdrawal within 49 hours5.671296e-4 days 0.0136 hours 8.101852e-5 weeks 1.86445e-5 months . Additionally, commensurate with the addition of the new MODES of Applicability, new Surveillance Requirements are being adding. ITS SR 3.3.1.14 has been added for Function 1 to perform a TADOT every 18 months, but is modified by a Note that states that the verification of the setpoint is not required. ITS SR 3.3.1.4 has been added for Function 17 and 18 to perform a TADOT every 31 days, but is modified by a Note, which states that the Surveillance must be performed on the reactor trip bypass breaker prior to placing the bypass breaker in service. This changes the CTS by requiring the Manual Reactor Trip channels and the Reactor Trip Breakers (RTBs) trains to be OPERABLE in MODES 3, 4, and 5 when the

Rod Control System is capable of rod withdrawal or when one or more rods are not fully inserted. Furthermore, this change adds an ACTION to take when the Manual Reactor Trip channels and the Reactor Trip Breakers (RTBs) trains are inoperable in MODES 3, 4, and 5 when the Rod Control System is capable of rod withdrawal or when one or more rods are not fully inserted. It also adds additional Surveillance Requirements for the new MODE of Applicability.

This change is acceptable because in MODE 3, 4, or 5 if one or more shutdown rods or control rods are withdrawn or the Rod Control System is capable of withdrawing the shutdown rods or the control rods, there is a possibility of an inadvertent control rod withdrawal. Therefore, action must be taken to restore the channel or train or to place the unit in a condition where there are no withdrawn rods and the ability to withdraw rods is precluded. This change is also acceptable because the new Required Actions and Completion Times are used to establish remedial measures that must be taken in response to the degraded conditions in order to minimize risk associated with continued operation while A ttachment 1, Volume 8, Rev. 0, Page 33 of 517 A ttachment 1, Volume 8, Rev. 0, Page 33 of 517 Enclosure (1 of 8), Q&A to Attachment 1, Volume 8 (Section 3.3) Page 40 of 41 Enclosure (1 of 8), Q&A to Attachment 1, Volume 8 (Section 3.3) Page 40 of 41 17 (Reactor Trip Breakers and Independently Test Shunt and Undervoltage Trip Attachments)
