Table M More Restrictive Changes Section 1.0 - Use and Application ITS # CTS # DOC # Description of Change ITS Requirement CTS Requirement ITS 1.0 CTS 1.0 M.1 The CTS definition for CHANNEL FUNCTIONAL TEST states the following: "A CHANNEL FUNCTIONAL TEST shall be the injection of a simulated signal into the channel as close to the primary sensor as practicable to verify OPERABILITY including alarm and/or trip functions". The corresponding ISTS definition for CHANNEL OPERATIONAL TEST adds the following requirements to the CTS definition: " The COT shall include adjustments, as necessary, of the required alarm, interlock, and trip setpoints required for channel OPERABILITY such that the setpoints are within the necessary range and accuracy. The COT may be performed by means of any series of sequential, overlapping, or total channel steps". The CTS definition is being revised to incorporate the additional ISTS requirements. 1.1 Definitions 1.11 ITS 1.0 CTS 1.0 M.2 The CTS shutdown and refueling Mode requirements in Table 1.1 that specify the transition between shutdown and refueling Modes are revised consistent with the ISTS. The CTS specifies Mode 6 entry when the reactor vessel head is unbolted or removed. The corresponding ISTS Table 1.1-1 requirement for Mode 6 specifies that one or more reactor vessel head closure bolts be less than fully tensioned. Additionally, the ISTS provides a corresponding condition for the reactor vessel head bolts in Modes 4 and 5. The ISTS specifies that in Modes 4 and 5 the reactor vessel head bolts be fully tensioned. This changes the CTS by adding new and different Mode definition requirements for vessel head bolts that define different transition points between the shutdown Modes and Refueling Mode. 1.1 Definitions Table 1.1 ITS 1.0 CTS 1.0 M.3 Unit 1 only. New definitions are added for MASTER RELAY TEST, ACTUATION LOGIC TEST, and SLAVE RELAY TEST consistent with the ISTS. The CTS is revised to conform to the ISTS. This changes the CTS by the addition of new and more specifically defined requirements for instrumentation surveillance testing. 1.1 Definitions 1.0 Definitions ITS 1.0 CTS 1.0 M.4 A new definition is included for the TRIP ACTUATING DEVICE OPERATIONAL TEST (TADOT) consistent with the ISTS. The proposed change revises the CTS by adding a new and more specific requirement for instrumentation surveillance testing. 1.1 Definitions 1.0 Definitions BVPS Units 1 and 2 Page 1 of 52 Rev. 1.5 Table M More Restrictive Changes Section 2.0 - Safety Limits ITS # CTS # DOC # Description of Change ITS Requirement CTS Requirement NONE BVPS Units 1 and 2 Page 2 of 52 Rev. 1.5 Table M More Restrictive Changes Section 3.0 - LCO and SR Applicability ITS # CTS # DOC # Description of Change ITS Requirement CTS Requirement ITS 3.0 CTS 3/4.0 M.1 CTS 4.0.2 states, "Each Surveillance Requirement shall be performed within the specified time interval with a maximum allowable extension not to exceed 25 percent of the surveillance interval." ISTS SR 3.0.2 introduces a limitation to the application of the surveillance interval extension provided by CT S 4.0.2. ISTS SR 3.0.2 states that "For Frequencies specified as "once," the above interval extension does not apply." The CTS is revised to be consistent with the ISTS. This changes the CTS by limiting the application of the surveillance interval extension permitted by CTS 4.0.2.

3.1.2 CTS 3.1.1.1 M.1 ITS SR 3.1.2.1 requires the core reactivity balance to be determined to be within 1% k/k of the predicted value once prior to entering MODE 1 after each refueling. The CTS does not contain a similar requirement. This changes the CTS by adding an additional performance requirement for the core reactivity balance SR.
SR 3.1.2.1 NA ITS 3.1.1 &
3.1.2 CTS 3.1.1.1 M.2 CTS 4.1.1.1.1.e requires SDM to be determined to be within its limit every 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> when in MODES 3, 4, and 5. ITS SR 3.1.1.1 requires SDM to be determined to be within its limit in MODE 2 with K eff < 1.0, and MODES 3, 4, and 5. This changes the CTS by expanding the applicability of the Surveillance to include MODE 2 with Keff < 1.0. SR 3.1.1.1 4.1.1.1.1.e ITS 3.1.1 CTS 3.1.1.2 NONE ITS-NA CTS 3.1.1.3 NONE ITS 3.1.3 CTS 3.1.1.4 M.1 The CTS 3.1.1.4 Applicability for MTC is Mode 1 and Mode 2 with Keff 1.0. The CTS Actions require the unit to be placed in Mode 3 when the MTC limit is not met. The ISTS applicability for the lower limit includes Modes 1, 2, and 3. The ISTS Action applicable when the lower MTC limit is not met requires that the plant be placed in Mode 4. Consistent with the ISTS, the CTS applicability is expanded to include not only Mode 1 and Mode 2 with Keff 1.0 but all of Mode 2 and all of Mode 3 for the lower MTC limit. In addition, the CTS Action requirement applicable when the lower MTC limit is not met is also revised consistent with the ISTS. 3.1.3 Applicability and Action 3.1.1.4 Applicability and Action ITS 3.1.3 CTS 3.1.1.4 M.2 CTS Surveillance 4.1.1.4.2.b verifies the lower MTC limit is met. The CTS surveillance requires that MTC be verified "At any THERMAL POWER, within 7 EFPD after reaching a RATED THERMAL POWER equilibrium boron concentration of 300 ppm". The ISTS surveillances that verify the lower MTC limit add the following requirements for verifying this limit " If the MTC is more negative than the 300 ppm Surveillance limit (not LCO limit) specified in the COLR, SR 3.1.3.2 shall be repeated once per 14 EFPD during the remainder of the fuel cycle. SR 3.1.3.2 need not be repeated if the MTC measured at the equivalent of equilibrium RTP-ARO boron concentration of 60 ppm is less negative than the 60 ppm Surveillance limit specified in the COLR". The CTS is revised by the addition of these new ISTS requirements for verification of the lower MTC limit.

The corresponding ISTS Action requires that additional Actions be taken in this condition to verify SDM or restore SDM to within limits within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> as well as requiring the unit to be placed in Mode 3 in 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />. The CTS is revised to adopt the additional ISTS Actions for SDM.
3.1.4 Action 3.1.3.1 Action ITS 3.1.4 CTS 3.1.3.1 M.2 CTS 3.1.3.1, Action c, states that with one rod misaligned, POWER OPERATION may continue provided that certain actions are completed within one hour. If those actions are not complete, CTS 3.0.3 would be entered which allows 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> to initiate action and would require entry into MODE 3 within the following 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />. Including the hour allowed in Action c, a total minimum time of 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> would be allowed before having to enter Mode 3.
The proposed ISTS Condition C, states that if the Required Actions and associated Completion Times are not met, the unit must be in MODE 3 in 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />. The shortest Completion Time in the affected Actions is one hour. Therefore, under the ISTS, the minimum time to enter MODE 3 is 7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br />. This changes the CTS by reducing the time that would be allowed before Mode 3 must be entered when the Actions for a misaligned rod have not been completed within the allowed time.
3.1.4 Action 3.1.3.1 Action ITS 3.1.7.2 CTS 3.1.3.2 (Unit 2) M.1 CTS 3.1.3.2 does not contain an Action to follow if the Required Actions cannot be met. Therefore, CTS 3.0.3 would be entered which would allow 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> to plan a shutdown and be in MODE 3 within 7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br />. ISTS 3.1.7 contains Action E which states that the plant must 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 /> if the Required Actions and associated Completion Times are not met. The CTS is revised to incorporate the ISTS Action. This changes the CTS by eliminating the one hour in LCO 3.0.3 to plan a shutdown and, consequently, allowing one hour less for the unit to be in MODE 3.
3.1.7.2 Action 3.1.3.2 Action ITS 3.1.7.1 CTS 3.1.3.2 (Unit 1) M.1 CTS surveillance 4.1.3.2.1.a is modified by an
- footnote that specifies rod position overlap be verified as follows "During startup and shutdown, overlap must be checked for all control banks at the respective bank overlap height transition points." The corresponding ISTS surveillance SR 3.1.6.3 specifies "Verify sequence and overlap limits specified in the COLR are met for control banks not fully withdrawn from the core every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />." The CTS surveillance is revised consistent with the ISTS. This changes the CTS by 1) requiring that the rod bank withdrawal sequence as well as overlap be verified, 2) that the applicable limits be specified in the COLR, and 3) that the surveillance be performed every SR 3.1.6.3 4.1.3.2.1 BVPS Units 1 and 2 Page 5 of 52 Rev. 1.5

ITS 3.1.4 CTS 3.1.3.4 NONE ITS 3.1.5 CTS 3.1.3.5 M.1 The CTS 3.1.3.5 Actions provide the option to "Declare the rod to be inoperable and apply Specification 3.1.3.1" within an hour. The ISTS Actions require that SDM be verified or restored within an hour. The CTS Actions are revised to conform to the ISTS Actions. This changes the CTS by eliminating the option to declare a rod inoperable and apply Specificati on 3.1.3.1.
3.1.5 Actions 3.1.3.5 Actions ITS 3.1.5 CTS 3.1.3.5 M.2 CTS 3.1.3.5 is applicable in MODE 1 and MODE 2 with k eff 1.0. The corresponding ISTS 3.1.5 is applicable in MODES 1 and 2. The CTS is revised to conform to the ISTS. This changes the CTS by expanding the applicability from MODE 2 with the reactor critical to all of MODE 2 (which includes the approach to criticality). 3.1.5 Applicability 3.1.3.5 Applicability ITS 3.1.6 CTS 3.1.3.6 M.1 CTS LCO 3.1.3.6 requires the control banks to be within the insertion limits specified in the CORE OPERATING LIMITS REPORT. ITS LCO 3.1.6 requires the control banks to be within the insertion, sequence, and overlap limits specified in the COLR. ISTS Condition B provides Actions for not meeting the overlap and sequence requirements, and ISTS SR 3.1.6.3 requires verification of the overlap and sequence every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. The CTS is revised to conform to the ISTS. This changes the CTS by adding requirements (LCO, Action, and Surveillance) for the overlap and sequence limits to the Insertion Limits TS.

ITS 3.1.9 CTS 3.10.3 (Unit 2) CTS 3.10.4 (Unit 1) M.1 CTS 3.10.3 provides an exception to CTS 3.1.1.4, 3.1.3.1, 3.1.3.5, and 3.1.3.6 during the performance of PHYSICS TESTS and provides restrictions that must be followed when utilizing the exception. The corresponding ISTS Test Exception (ITS 3.1.9) provides an exception to the equivalent ITS LCOs and adds a requirement to the restrictions that must be followed. The ISTS adds the requirement that SDM must be within the limits provided in the COLR. In addition, the ISTS adds a Surveillance to verify the SDM every 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> and ACTIONS to follow if the SDM limit is not met. The CTS is revised to conform to the additional ISTS requirements. This changes the CTS by imposing additional requirements on the application of the test exception LCO.
3.1.9 LCO & SR 3.10.3 ITS 3.1.9 CTS 3.10.3 (Unit 2) CTS 3.10.4 (Unit 1) M.2 CTS 4.10.3.1 requires THERMAL POWER to be verified to be 5% once per hour. The corresponding ISTS Surveillance requires the verification be performed every 30 minutes. This changes the CTS by increasing the Frequency of the THERMAL POWER verification.
SR 3.1.9.3 4.10.3.1 ITS 3.1.10 CTS - NA M.1 The CTS is revised by the addition of a new Technical Specification (3.1.10, "RCS Boron Limitations < 500 0F"). The addition of this new specification is consistent with the Westinghouse Owners Group (WOG) TSTF-453. TSTF-453 was developed to address issues in Westinghouse Nuclear Safety Advisory Letter (NSAL)-00-016.

However, under the general rules of TS usage (CTS 3.0.2) these measurements do not have to be completed if at any time compliance with the LCO is reestablished. The corresponding ISTS 3.2.2 Condition A contains a Note that states, "Required Actions A.2 and A.3 must be completed whenever Condition A is entered." ISTS Required Actions A.2 and A.3 require performance of a F NH measurement every 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> and prior to exceeding 50% RTP, 75% RTP, and within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after THERMAL POWER 95% RTP. The CTS is revised to conform to the ISTS. This changes the CTS by the addition of the ISTS Note. The ISTS Note requires the Actions that measure F NH prior to each specified power level and every 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to be completed even if F NH is restored to within its limit and compliance with the LCO is re-established. 3.2.2 Condition A 3.2.3 Action c ITS 3.2.4 CTS 3.2.4 M.1 CTS Action f requires that peaking factors be verified within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after reaching RTP or within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> after increasing THERMAL POWER.

CTS Action f (ITS A.6) requires a follow up verification of core status by measuring peaking factors after power has been increased. However, under the general rules of TS usage (CTS 3.0.2) the peaking factor measurements required by CTS Action f (ITS A.6) do not have to be completed if compliance with the LCO is reestablished in CTS Action e (ITS A.5). Therefore, the ISTS 3.2.4 Action A.5 contains a Note that states, "Required Action A.6 must be completed whenever Required Action A.5 is performed."

The CTS list of interlocks includes P-10 and P-13. The P-10 and P-13 interlocks function to provide the P-7 interlock (low power permissive). Although the CTS references the P-7 permissive in several RTS Functions, the CTS does not specifically list the P-7 interlock in RTS Function 23. The CTS relies on specifying the components of the P-7 interlock (P-10 and P-13) to address the function of P-7. The ISTS list of interlocks includes P-10, P-13, and P-7. The CTS is revised to conform to the ISTS. This changes the CTS by adding a specific RTS line item Function for the P-7 interlock in Tables 3.3-1 and 4.3-1. Table 3.3.1-1 Tables 3.3-1 and 4.3-1 ITS 3.3.1 CTS 3.3.1.1 M.2 CTS Note 3 in Table 3.3-1 states the following; " With the reactor trip system breakers in the closed position and the control rod drive system capable of rod withdrawal." This CTS Note is used to modify the Applicability of RTS functions needed to mitigate the consequences of rod withdrawal events. The corresponding ISTS Note (a) states; " With Rod Control System capable of rod withdrawal or one or more rods not fully inserted." The CTS is revised to conform to the ISTS. This changes the CTS by adding the requirement to the applicability of whenever one or more rods are not fully inserted. Table 3.3.1-1 Note (a) Table 3.3-1 Note 3 ITS 3.3.1 CTS 3.3.1.1 M.3 CTS Action 2.a.2, for an inoperable Power Range Neutron Flux Channel, states "place the inoperable channel in trip within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and perform SR 4.2.4." The referenced SR requires that the Quadrant Power Tilt Ratio be verified within the limit. The corresponding ISTS Action in Condition D specifies the performance of a surveillance to verify QPTR but includes a periodic frequency of "Once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />" for performing this surveillance. The CTS Action 2.a.2 is revised to conform with the corresponding ISTS Action in Condition D. This changes the CTS by specifying a periodic frequency for performing the required
surveillance.
Action D Action 2.a.2 ITS 3.3.1 CTS 3.3.1.1 M.4 CTS Action 7a requires that "the inoperable channel is placed in the tripped condition within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />". The corresponding ISTS Action Conditions E, K, and L specify the same Action but also includes the requirement that if the channel is not placed in the trip condition the affected unit must be removed from the Applicable Mode associated with the RTS Function. This additional ITS Action is to reduce power to Mode 3 in ITS Condition E, or reduce power to less than P-7 for ITS Condition K, and to reduce power to less than P-9 for ITS Condition L. The CTS is revised to include the ISTS Action requirement to remove the unit from the Applicable Mode for the affected RTS Function. This changes the CTS by including a specific Action to remove the unit from the Applicable Mode of the affected RTS Function if the Action to place the channel in trip is not met.
Actions E, K, & L Action 7a ITS 3.3.1 CTS 3.3.1.1 M.5 CTS Action 8 applies to the Turbine Trip (Stop Valve Closure) RTS Function.

The corresponding ISTS Action Condition L specifies the same Action for this RTS Function but also includes the requirement that if the channel is not placed in the trip condition the affected unit must be removed from the Applicable Mode associated with the RTS Function. The Action L Action 8 BVPS Units 1 and 2 Page 10 of 52 Rev. 1.5 Table M More Restrictive Changes Section 3.3A - 3.3.1, Reactor Trip System Instrumentation ITS # CTS # DOC # Description of Change ITS Requirement CTS Requirement additional ITS Action requires that power be reduced to less than P-9 for ITS Condition L. The CTS is revised to include the ITS Action requirement to remove the unit from the Applicable Mode for the affected RTS Function. This changes the CTS by including a specific Action to remove the unit from the Applicable Mode of the affected RTS Function if the Action to place the channel in trip is not met. ITS 3.3.1 CTS 3.3.1.1 M.6 CTS Action 11 applies to the Reactor Coolant Pump (RCP) breaker position RTS Function. Action 11 requires that "the inoperable channel is placed in the tripped condition within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />". The corresponding ISTS Action Condition K specifies the same Action for this RTS Function but also includes the requirement that if the channel is not placed in the trip condition the affected unit must be removed from the Applicable Mode associated with the RTS Function. The additional ITS Action requires that power be reduced to less than P-7 for ITS Condition K. The CTS is revised to include the ITS Action requirement to remove the unit from the Applicable Mode for the affected RTS Function. This changes the CTS by including a specific Action to remove the unit from the Applicable Mode of the affected RTS Function if the Action to place the channel in trip is not met.
Action K Action 11 ITS 3.3.1 CTS 3.3.1.1 M.7 Unit 2 only (Unit 1 does not have an Action 44). Action 44 is applicable to the Unit 2 RTS Interlock Functions (i.e., P-6, P-8, P-9, etc.). The Unit 2 CTS Action 44 requires that action be taken "With less than the Minimum Number of Channels OPERABLE-." The CTS minimum channels operable requirement for the RTS Interlock Functions is one less than the total number of Interlock channels. As such the CTS does not require any Action when a single interlock channel is inoperable. The corresponding ITS Actions Conditions O and P specify that Action be taken when "one or more channels are inoperable". The ITS Actions are based on the "Required" or total number of channels. As such, the ITS Actions for the RTS interlocks require that action be initiated as soon as a single interlock channel becomes inoperable. The CTS is revised to conform to the ISTS. This changes the CTS by specifying that action be initiated when a single interlock channel becomes inoperable.
Action O & P Action 44 ITS 3.3.1 CTS 3.3.1.1 M.8 Unit 2 only (Unit 1 does not have an Action 44). Action 44 is applicable to the Unit 2 RTS Interlock Functions (i.e., P-6, P-8, P-9, etc.). CTS Action 44 requires that the interlock be determined to be "in its required state for the existing plant condition". The default action requirement if the interlock can not be determined to be in the required state within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> is to apply Specification 3.0.3.

ITS 3.3.1 CTS 3.3.1.1 M.9 Unit 1 only (Unit 2 does not use Action 3 or 12 for the RTS Interlock Functions). CTS Action 3 is applicable to the Unit 1 RTS P-6 Interlock Function. CTS Action 12 is applicable to the other RTS interlocks (P-8, P-9, P-10). The CTS Action 3 and 12 require that action be taken "With less than the Minimum Number of Channels OPERABLE-." The CTS minimum channels operable requirement for the RTS Interlock Functions is one less than the total number of Interlock channels. As such the CTS does not require any Action when a single interlock channel is inoperable. The corresponding ITS Action Conditions O and P specify that Action be taken when "one or more channels are inoperable". The ITS Actions are based on the "Required" or total number of channels. As such, the ITS Actions for the RTS interlocks require that action be initiated as soon as a single interlock channel becomes inoperable. The CTS is revised to conform to the ISTS. This changes the CTS by specifying that action be initiated when a single interlock channel becomes inoperable.
Actions O & P Action 3 ITS 3.3.1 CTS 3.3.1.1 M.10 Unit 1 only (Unit 2 already requires the P-10 interlock in Modes 1 and 2). The CTS Applicability for the P-10 RTS Interlock Function requires the Function to be operable in Mode 1. The ISTS Applicability for the P-10 RTS Function (and the BVPS Unit 2 Applicability) require the P-10 RTS Interlock Function to be operable in Modes 1 and 2. The Unit 1 CTS is revised to conform to the ISTS (and BVPS Unit 2). This changes the CTS by requiring the P-10 RTS Interlock Function on Unit 1 CTS Tables 3.3-1 and 4.3-1 to be operable in Mode 2 as well as Mode 1. P-10 Applicability P-10 Applicability ITS 3.3.1 CTS 3.3.1.1 M.11 The CTS daily channel calibration surveillance assigned to the power range neutron flux high setpoint on Table 4.3-1 consists of adjusting the power range instrument channels to match the calorimetric heat balance calculation each day. The CTS surveillance is modified by Note 2 that states the surveillance is only required above 15% RTP. The corresponding ISTS SR 3.3.1.2 specifies that the power range channel output be adjusted if calorimetric heat balance calculation results exceed power range channel output by more than + 2% RTP. The ITS surveillance is modified by a Note that states the surveillance is not required to be performed until 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after Thermal Power is 15% RTP. The CTS is revised to be consistent with the ITS. This changes the CTS by adding more specific requirements for the performance of the daily adjustment of the power range channels to the results of the calorimetric heat balance calculation. SR 3.3.1.2 Note Table 4.3-1 Note 2 ITS 3.3.1 CTS 3.3.1.1 M.12 The CTS monthly channel calibration requirement associated with the power range neutron flux high setpoint on Table 4.3-1 is modified by Note 3. CTS Note 3 specifies that the surveillance consist of an incore-excore comparison every 31 EFPD above 15% RTP and that the Nuclear Instrumentation System (NIS) be recalibrated (adjusted) if the absolute difference is > 3%.

The CTS is revised to conform to the proposed BVPS ITS surveillance requirement. This changes the CTS by placing a new time restriction on the first performance of the surveillance after exceeding the specified power. ITS 3.3.1 CTS 3.3.1.1 M.13 The CTS surveillances for the Power Range Low setpoint and Intermediate Range RTS Functions specified in Table 4.3-1 require a Channel Functional Test (CFT) to be performed Prior to Startup (S/U) if not performed in the previous 31 days (Note 1). The corresponding ISTS surveillance SR 3.3.1.8 (BVPS ITS SR 3.3.1.7) also requires a Channel Operational Test (COT) prior to reactor startup. However, the ISTS Surveillance Frequency is modified by a Note that states the surveillance is only required if it has not been performed in the previous 92 days. The ISTS surveillance also requires the performance of the COT 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> after reducing power below P-10 during shutdowns and every 92 days on a periodic basis as long as the plant is maintained in the Applicable Mode. The ISTS surveillance also requires a verification that the P-6 and P-10 interlocks are in their required state for existing plant conditions. The CTS surveillance requirements for these RTS Functions are revised to conform to the ISTS. This changes the CTS requirement to perform the surveillance prior to reactor startup by the addition of requirements to perform the surveillance during a shutdown (within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> after reducing power below P-10) and the addition of the requirement to repeat the surveillance every 92 days on a periodic basis after startup or during a shutdown while maintaining the plant in the Applicable Mode (Mode 2 and Mode 1 < P-7). The ISTS requirement to verify the state of the P-6 and P-10 interlocks are also included in the CTS requirement.
SR 3.3.1.7 Table 4.3-1 CFT ITS 3.3.1 CTS 3.3.1.1 M.14 The Unit 1 and 2 CTS surveillances for the Power Range High Positive Rate, Overpower and Overtemperature T RTS Functions and the Unit 2 surveillances for the Pressurizer Pressure - Low RTS Function specified on Table 4.3-1 include the requirement to perform a channel calibration. The corresponding ISTS channel calibration surveillance requirement (ITS SR 3.3.1.10) includes an additional requirement (Note) that affects the RTS Functions listed above. The ISTS channel calibration surveillance requirement includes a Note that requires the verification that time constants are adjusted to the prescribed values. The RTS Functions listed above have time constants associated with their allowable values and trip setpoints. The CTS surveillance requirements are revised to conform to the ISTS. This changes the CTS requirements by including a specific requirement to verify the time constants associated with the RTS Functions listed above.
SR 3.3.1.10 Table 4.3-1 Channel Calibration ITS 3.3.1 CTS 3.3.1.1 M.15 The CTS surveillances for the Source Range RTS Function specified on Table 4.3-1 include the requirement to perform a Channel Functional Test (CFT) quarterly. The CTS CFT requirement is modified by Note 8 which states that " Below P-6, not required to be performed for source range instrumentation prior to entering MODE 3 from MODE 2 until 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> after entry into MODE 3." The corresponding BVPS proposed ITS surveillance (SR 3.3.1.6) requires that a Channel Operational Test (COT) be performed quarterly. The ITS surveillance is modified by a note that states "Not required to be performed for source range SR 3.3.1.6 Table 4.3-1 CFT BVPS Units 1 and 2 Page 13 of 52 Rev. 1.5 Table M More Restrictive Changes Section 3.3A - 3.3.1, Reactor Trip System Instrumentation ITS # CTS # DOC # Description of Change ITS Requirement CTS Requirement instrumentation until 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> after power has been reduced below P-6."

ITS 3.3.1 CTS 3.3.1.1 M.16 Unit 1 only. The Unit 1 CTS surveillances specified on Table 4.3-1 for the Turbine Trip RTS Functions do not include channel calibrations every refueling cycle. The corresponding ISTS surveillance requirements (SR 3.3.1.10) (and the Unit 2 surveillance requirements) for this RTS Function include a requirement to perform channel calibrations every 18 months. The Unit 1CTS is revised to conform to the ISTS and Unit 2. This changes the Unit 1CTS by adding the requirement to perform channel calibrations on the Turbine Trip RTS Functions every 18 months.

The Unit 1 CTS surveillance requirements specified on Table 4.3-1 for the manual reactor trip function do not include the Applicable Modes for this RTS Function. In addition, the surveillance requirements specified on Table 4.3-1 for the power range neutron flux - low trip setpoint RTS Function do not include Mode 1 below the P-10 Interlock in the Applicable Modes for this RTS Function. The ISTS includes all the Applicable Modes for each RTS Function in the single combined ISTS Table 3.3.1-1. The CTS is revised to conform to the ISTS. This changes the CTS Table 4.3-1 by combining it with CTS Table 3.3-1 such that each RTS Function has all the associated requirements (including the Applicable Modes as modified by footnotes (a) and (b)) specified on a single Table. The proposed change results in the applicable Modes being correctly and consistently specified each affected Function in the RTS TS. Table 3.3.1-1 Applicability Table 4.3-1 Applicability ITS 3.3.1 CTS 3.3.1.1 M.18 CTS Table 3.3-1 contains a line item that addresses the requirements for the reactor Trip Breakers (RTBs). CTS Table 3.3-1 does not contain any reference to the RTB bypass breakers. The corresponding ISTS Table 3.3.1-1 contains a footnote (g) that modifies the requirements for the RTBs such that the RTB requirements are applicable to an RTB bypass breaker when the bypass breaker is racked in and closed to bypass an RTB. The CTS is revised to conform to the ISTS. This changes the CTS by providing specific requirements that are applicable to the bypass breakers when they are used in place of the RTBs. Table 3.3.1-1 Table 3.3-1 ITS 3.3.1 CTS 3.3.1.1 M.19 A new ITS surveillance BVPS ITS SR 3.3.1.9 (ISTS 3.3.1.6) is added to the CTS surveillances for the power range neutron flux high trip setpoint on CTS Table 4.3-1. The new surveillance requires that the excore nuclear instrumentation channels be calibrated to agree with incore detector measurements once per refueling cycle. The new surveillance is modified by a note that establishes the criteria for the initial performance following a refueling outage. The note requires that the surveillance be performed within 7 days after thermal power exceeds 50% RTP. The CTS is revised to incorporate this new surveillance requirement.

The CTS Action states "Neither breaker shall be bypassed while one of the diverse trip features is inoperable except for the time required for performing maintenance to restore the breaker to OPERABLE status." The ISTS contains a corresponding note (#2) in the Action Condition (ITS Condition N) for an inoperable RTB that states "One RTB may be bypassed for up to 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> for maintenance on undervoltage or shunt trip mechanisms, provided the other train is OPERABLE." The CTS allowance is revised to conform to the ISTS note.

Specification 3.0.3 would require that the plant be placed in a Mode where the requirements of CTS 3.3.3.1 were no longer applicable. The PAM ITS does not include an exception to ITS LCO 3.0.3. As such, the proposed change would result in ITS LCO 3.0.3 being applicable if the PAM ITS did not contain an appropriate Action for an inoperable condition or if the ITS Actions were not met.

The CTS Action requires that an explanation of why the inoperable instrument was not corrected in a timely manner be included in the next Annual Radioactive Effluent Release Report. The corresponding ITS Action if the Containment Area Radiation Monitor channel(s) are not restored to operable status within the specified Completion Time requires immediate compliance with ITS Specification 5.6.5. ITS Specification 5.6.5 states that "a report shall be submitted within the following 14 days. The report shall outline the preplanned alternate method of monitoring, the cause of the inoperability, and the plans and schedule for restoring the instrumentation channels of the Function to OPERABLE status."

The CTS Table specifies that a Channel Check for AFW Flow Rate be performed only upon a unit startup (S/U). The S/U frequency for this surveillance is modified by a note that states "Channel check to be performed in conjunction with Surveillance Requirement 4.7.1.2.7 following an extended plant outage." CTS 4.7.1.2.7 verifies AFW flow to the SGs after the Unit has been in Mode 5 or 6 for more than 30 days.
The corresponding ITS SR 3.3.4.1 requires the performance of a CHANNEL CHECK every month for each required instrumentation channel that is normally energized. The CTS is revised to conform to the ISTS surveillance requirement. This changes the CTS by replacing the requirement to perform an AFW flow channel check once per unit startup following an extended outage with the requirement for a channel check to be performed every month.

In addition, the CTS is revised to include an Action to enter the applicable plant systems specification (3.7.10) for an inoperable train of CREVS. The Action for an inoperable CREVS train in 3.7.10 allows 7 days of operation in this condition before the CREVS train must be restored to operable status (initiation instrument channel or train restored to operable status) or the plant must be placed in a condition where the affected CREVS train is no longer required operable.

The CTS is revised to incorporate the ITS default Action Conditions C and D. This changes the CTS by providing clear Action requirements to implement if the primary Actions that address the inoperable condition are not met within the required completion time. ITS 3.3.7 CTS 3.3.3.1 M.5 CTS 3.3.3.1 contains the requirements for radiation monitors, including the monitors used to actuate the Control Room Emergency Ventilation System (CREVS). CTS 3.3.3.1 does not contain requirements for m anual initiation of the CREVS. ITS 3.3.7 " CREVS Actuation Instrumentation," contains all the instrumentation requirements for the CREVS including the radiation monitors. ITS 3.3.7 also includes the requirements for the manual switches associated with each CREVS train. The CREVS manual initiation Function is applicable in MODES 1, 2, 3, and 4, and During the movement of recently irradiated fuel assemblies, or during movement of fuel assemblies over recently irradiated fuel assemblies." Two trains of manual initiation are required operable and a TADOT surveillance is assigned to the manual function. The CTS is revised to conform to the ITS. This changes the CTS by adding the requirements for the manual CREVS initiation Function to the TS.

SRs NA ITS 3.3.7 CTS 3.3.3.1 M.6 CTS LCO 3.3.3.1 states "The radiation monitoring instrumentation channels shown in Table 3.3-6 shall be OPERABLE." Table 3.3-6 lists the radiation monitors required for the Control Room Area. ITS LCO 3.3.7 states "The Control Room Emergency Ventilation System (CREVS) actuation instrumentation for each Function in Table 3.3.7-1 shall be OPERABLE." ITS Table 3.3.7-1 lists all the required CREVS instrument functions which includes the containment isolation Phase B (CIB) signal. The ITS Table 3.3.7-1 specification of the CIB actuation includes a reference to the requirements for the CIB being specified in ITS 3.3.2, ESFAS Instrumentation. The CTS is revised to conform to the ISTS. This changes the CTS by specifying an additional instrumentation actuation function for the CREVS. Table 3.3.7-1 Table 3.3-6 ITS 3.3.7 CTS 3.3.3.1 M.7 CTS LCO 3.3.3.1 Surveillance Requirement 4.3.3.1 states "Each radiation monitoring instrumentation channel shall be demonstrated OPERABLE by the performance of the CHANNEL CHECK, CHANNEL CALIBRATION and CHANNEL FUNCTIONAL TEST operations during the modes and at the frequencies shown in Table 4.3-3." The CTS does not include any requirements for the CREVS manual initiation function. ITS LCO 3.3.7 "Control Room Emergency Ventilation System (CREVS) Ac tuation Instrumentation," specifies the manual initiation Function and requires SR 3.3.7.3 to be performed on the manual function. The ITS SR requires a TADOT to be performed every 18 months. SR 3.3.7.3 is modified by a Note that states "Verification of setpoint is not required." This changes the CTS by adding a surveillance requirement that is not currently specified.

The corresponding Actions in proposed ITS 3.3.7 are simplified and treat each Unit equally and do not contain provisions for Unit 1 to credit the Unit 2 radiation monitors.

The proposed change results in a more simplified set of Actions for Unit 1 that are consistent with the proposed Unit 2 Actions and the corresponding ISTS Actions. ITS 3.3.7 CTS 3.3.3.1 M.9 Unit 1 only. CTS 3.3.3.1 contains the Actions applicable when one or more control room area radiation monitors are inoperable. CTS Actions 41a) 2, 41b) 2, and 41b) 3 require that the control room be isolated from the outside atmosphere by closing the series air intake and exhaust isolation dampers. The corresponding ITS 3.3.7 Action Conditions A and B require that a CREVS train be placed in the emergency pressurization mode of operation. The emergency pressurization mode of operation includes isolation of the control room ventilation intake and exhaust ducts as well as the start of a CREVS fan aligned to provide filtered makeup air to pressurize the control room. The CTS Actions are revised to conform to the ITS Actions. This changes the CTS Actions by requiring the control room to be placed in the emergency pressurization mode of operation instead of simply being isolated.

The Unit 2 Turbine Trip and Feedwater Isolation consists of three ESFAS Functions. The requirements for the Safety Injection input are addressed separately under Function 1 in the CTS. However, the operability requirements for the SG Water Level High-High Function and the Automatic Actuation Logic and Relays Function are addressed under the Turbine Trip and Feedwater Isolation Function. The CTS SG Water Level High-High Function is required operable in Modes 1-3 and the CTS Automatic Actuation Logic and Relays Function is only required operable in Modes 1-2. The corresponding ISTS Functions indicate that Mode 3 is optional (bracketed). The CTS is revised to make both these Functions required operable in Mode 3. This changes the CTS by requiring the Automatic Actuation Logic and Relays Function operable in Mode 3 as well as Modes 1-2. Table 3.2-1 Turbine Trip and Feedwater Isolation Function Table 3.3-3 Turbine Trip and Feedwater Isolation Function ITS 3.3.2 CTS 3.3.2.1 M.2 CTS Action statement 13 applies the trains of Automatic Actuation Logic and requires that with an inoperable channel the plant be placed in Hot Standby (Mode 3) in 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and in Cold Shutdown (Mode 5) within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.

Action C Action 13 ITS 3.3.2 CTS 3.3.2.1 M.3 The CTS Actions require that "the inoperable channel is placed in trip [or in bypass]". The corresponding ISTS Action Conditions specify the same Action but also include the requirement that if the channel is not placed in the trip condition or bypassed the affected unit must be removed from the Applicable Mode associated with the ESFAS Function. The additional ISTS Action requires power and Mode reductions to place the affected unit in a Mode where the ESFAS Function is no longer required operable. The CTS is revised to include the ISTS Action requirement to remove the unit from the Applicable Mode for the affected ESFAS Function. This changes the CTS by including specific Action(s) to remove the unit from the Applicable Mode of the affected ESFAS Function if the Action is not met.

The Unit 1 general ESFAS surveillance requirement 4.3.2.1.1 specifies the instrumentation to be tested and the surveillances that must be performed in a similar manner as the corresponding Unit 2 general surveillance requirement. However, unlike Unit 2, the Unit 1 requirement does not specify that interlock, automatic actuation logic, and master and slave relay instrument functions are included in the ESFAS surveillance requirements. The corresponding ISTS ESFAS requirements do not include a general surveillance requirement similar to CTS 4.3.2.1.1. Instead, the ISTS surveillance requirements are specified in detail on Table 3.3.2-1. However, the ISTS ESFAS surveillance requirements, similar to the Unit 2 ESFAS TS, specify that testing be performed on interlock, automatic actuation logic, and master and slave relay instrument functions. The Unit 1 CTS surveillance 4.3.2.1.1 is revised to conform more closely to the corresponding Unit 2 and ISTS ESFAS surveillance requirements.

The corresponding ISTS 3.4.17 Action Condition B contains the same requirement to place the plant in Mode 5. However, the ISTS Action is modified by a note that requires the Action to be completed whenever the Condition is entered. The CTS does not contain a similar note that requires that the action be completed whenever it is started. The CTS is revised to conform to the ISTS. This changes the CTS by requiring the Action to be in Mode 5 to be completed whenever it is started.
Action B Action a ITS 3.4.18 CTS 3.4.1.5 M.1 CTS 3.4.1.5 LCO requires that the hot and cold leg isolation valves be closed until the isolated portion of the loop has been drained and refilled from the RWST or RCS. In addition, the CTS LCO requires that the hot and cold leg isolation valves be closed if the boron concentration in the isolated loop is less than the minimum required to satisfy the requirements of Specification 3.1.1.2 (Mode 5 SDM) and Specification 3.9.1 (Mode 6 boron LCO, Action, & SR NA BVPS Units 1 and 2 Page 28 of 52 Rev. 1.5 Table M More Restrictive Changes Section 3.4 - Reactor Coolant System ITS # CTS # DOC # Description of Change ITS Requirement CTS Requirement concentration). The corresponding ISTS 3.4.18 LCO requirements specify that the hot and cold leg isolation valves be closed if the boron concentration of the isolated loop is less than the boron concentration required to meet the SDM of LCO 3.1.1 (Mode 5) or boron concentration of LCO 3.9.1 (Mode 6). In addition, the ISTS LCO requires that the cold leg isolation valve be closed if the cold leg temperature of the isolated loop is [20]F below the highest cold leg temperature of the operating loops. The CTS is revised to be more consistent with the ISTS LCO requirements. However, the proposed change includes BVPS specific temperature requirements that differ from the ISTS temperature requirement described above. This changes the CTS by adding additional requirements (LCO, Action, and Surveillance) to verify an upper and lower temperature limit is met for the isolated loop being returned to service. ITS 3.4.18 CTS 3.4.1.5 M.2 The CTS applicability for isolated loop startup states: "Whenever an RCS loop has been isolated greater than 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> or drained(1)." The footnote (1) identifies that fuel must be in the vessel. The corresponding ISTS Applicability simply states "MODES 5 and 6." The CTS Applicability is revised to conform to the ISTS Applicability. This changes the CTS by eliminating the 4-hour isolation or loop drained allowance in the CTS Applicability and requiring the LCO to be applicable at all times in Modes 5 and 6. Applicability Applicability ITS 3.4.10 CTS 3.4.3 M.1 CTS 3.4.3 Action, requires that when one pressurizer safety valve is inoperable, it must be restored to OPERABLE status within 15 minutes or the plant must be placed in hot shutdown within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

The mode reductions required by the CTS Action are acceptable because of the availability of the remaining operable AFW train. If three AFW trains are inoperable, the CTS Action e precludes any Mode transitions that may place the plant in a condition that could increase the likelihood that the AFW would be required to support decay heat removal and requires that one AFW train be restored to operable status prior to initiating a plant transient. The corresponding ISTS Action Condition D for two inoperable AFW trains also contains a provision for three inoperable AFW trains and requires a plant shutdown to Mode 4 be made. The provision of the ISTS Action D for three inoperable AFW trains in MODE 1, 2 or 3 applies only to a turbine-driven AFW pump that is inoperable solely due to one required steam supply line being inoperable. Conversely, the ISTS Action E for three inoperable AFW trains (applicable when the turbine-driven AFW pump is inoperable for reasons other than a single inoperable steam supply line) continues to require the restoration of one AFW train prior to placing the plant in Mode 4. The corresponding CTS Actions are revised to incorporate this provision of the ISTS Actions. This changes the CTS by requiring a plant shutdown to Mode 4 when three AFW trains are inoperable if the turbine-driven pump is inoperable solely due to a single required steam supply being inoperable.

The corresponding ISTS surveillance contains a similar frequency for performance with the exception that the ISTS specifies that the surveillance is applicable after the plant has been in a "defueled" condition as well as in Modes 5 and 6. The CTS is revised to conform to the ISTS. This changes the CTS by expanding the operating conditions for which the cumulative time is tracked by CTS surveillance 4.7.1.2.7. As such, the proposed change requires the time spent in a defueled condition be accounted for as well as the time spent in Modes 5 and 6 for determining when surveillance 4.7.1.2.7 must be performed.

Action B Action b ITS 3.7.13 CTS 3.7.1.4 M.1 CTS Table 4.7-2 Item #2 allows the sampling frequency for the DOSE EQUIVALENT I-131 to be extended to once per 6 months whenever the gross activity determination indicates the iodine concentrations are below 10% of the allowable limits. ISTS SR 3.7.18.1 (ITS SR 3.7.13.1) does not provide for this extended time frame for determining the DOSE EQUIVALENT I-131 and requires verification of specific activity of the secondary coolant every 31 days whenever the unit is in MODES 1, 2, 3, and 4. The CTS surveillance is revised to conform to the ISTS fixed surveillance frequency of 31 days for determining DOSE EQUIVALENT I-131. This changes the CTS by revising the specified frequency for determining DOSE EQUIVALENT I-131 to 31 days instead of referencing the program specified on CTS Table 4.7-2. The proposed change also eliminates the need for CTS Table 4.7-2.

The CTS does not include a specific time in which the unit must be placed in Mode 3. Thus, the CTS would allow continued operation in Modes 2 and 3 with an open and inoperable MSIV for up to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> before Mode 4 must be entered.

Additionally, the ISTS requires a continuous check of the valve position to verify that it is closed while operating in Modes 2 or 3 (which is not required by the CTS). As long as the requirements of C.1 and C.2 are met, the ISTS permits continued operation in Modes 2 and 3.

The Unit 2 CTS requirements for SLCRS do not include a requirement to verify the fuel building integrity by verifying that the required SLCRS can maintain a negative pressure in the fuel building. The proposed ITS 3.7.12 includes a surveillance requirement (SR 3.7.12.3) to verify a SLCRS train can maintain the Unit 2 fuel building at a negative pressure. The proposed new surveillance contains a note that clarifies the surveillance is only applicable for fuel movement involving recently irradiated fuel in the fuel storage pool. The Note is necessary as the Unit 1 SLCRS is also required operable for fuel movement involving recently irradiated fuel inside containment. The new surveillance is only for the fuel building integrity and would not be appropriate if the Unit 1 SLCRS was only required for fuel movement inside containment. The containment penetration refueling requirements are addresses in ITS 3.9.3 of the technical specifications. The note does not affect the Unit 2 surveillance as the Unit 2 SLCRS is only required for fuel movement in the fuel building. Thus, the Unit 2 CTS is revised by the addition of a new surveillance requirement.

ITS SR 3.8.1.11 requires verification for each DG that it is capable of synchronizing with the offsite power source while carrying emergency loads. Upon a simulated restoration of offsite power, the emergency loads would be transferred to the offsite source and the DG would return to a specified condition. The Unit 2 DGs would return to a ready-to-load position and the Unit 1 DGs would be required to proceed through the shutdown sequence. The surveillance is required to be performed every 18 months. A note modifies the SR. The note states this surveillance shall not normally be performed in MODE 1, 2, 3, and 4. The note allows the performance of the SR in MODES 1, 2, 3, and 4 to reestablish OPERABILITY for the DG provides an assessment can determine that the safety of the plant can be maintained or enhanced.

ITS SR 3.8.1.12 requires verification that with a DG operating in a test mode and connected to its bus, an actual or simulated ESF actuation signal overrides the test mode. The actual or simulated signal would cause the DG to return to the ready-to-load condition. The surveillance is required to be performed every 18 months. Two notes modify the SR. Note 1 states that the SR is only applicable to Unit 2 only. The second note states this surveillance shall not normally be performed in MODE 1, 2, 3, and 4. The note allows portions of the SR to be performed in MODES 1, 2, 3, and 4 to reestablish OPERABILITY for the DG provides an assessment can determine that the safety of the plant can be maintained or enhanced.

The Category A parameters are electrolyte level, float voltage, and specific gravity. Two notes modify specific gravity requirements in CTS Table. Note (a) modifies the general requirement for specific gravity and states "Corrected for electrolyte temperature and level." Note (b) modifies the Category A and the allowable values of the Category B limits and states "Or battery charging current is less than (2) amps when on charge." The Category B limits apply to each connected cell. ITS SR 3.8.6.1 requires that the float current for each battery is verified 2 amps every 7 days.

The Note states "Not required to be met when battery terminal voltage is less than the minimum established float voltage of SR 3.8.4.1" This changes the CTS by eliminating a method for determining specific gravity requirements. ITS 3.8.4 ITS 3.8.6 ITS 3.8.9 CTS 3.8.2.3 M.4 CTS 4.8.2.3.2.b.1 states the parameters in Table 3.8-1 meet the Category B limits every 92 days and within 7 days after a battery discharge or overcharge condition. Category B parameters applies to each connected cell. ITS SR 3.8.6.3 states "Verify each battery connected cell electrolyte level is greater than or equal to minimum established design limits," every 31 days. This changes the CTS by requiring each connected cell electrolyte level be verified every 31 days instead of 92 days.

SR 3.9.2.1 4.9.2 ITS 3.9.2 CTS 3.9.2 M.4 CTS Surveillance Requirement 4.9.2 specifies testing for the source range instrumentation channels in Mode 6. The corresponding ISTS surveillances require the performance of a CHANNEL CALIBRATION on the source range monitors every 18 months. This 18-month surveillance is not specified in CTS 4.9.2. The CTS is revised to incorporate the ISTS 18-month channel Calibration requirement for the source range monitors. This addition changes the CTS by requiring a CHANNEL CALIBRATION every 18 months on each source range monitor.

The Unit 2 provisions that allow open PAL doors and other containment penetrations added by Amendment 116 to Unit 2 CTS 3.9.4 are eliminated from the TS.

In addition, the nonspecific completion time for the CTS Actions to "suspend operations involving-" is revised by the addition of an immediate completion time for these CTS Actions, also consistent with the ISTS. ITS 3.9.4 CTS 3.9.8.1 M.2 CTS 3.9.8.1 Actions b and c specify, in part, that "the residual heat removal loop may be removed from operation for up to 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> per 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> period" and that " the residual heat removal loop may be removed from operation for up to 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> per 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> period during the performance of Ultrasonic In-service Inspection inside the reactor vessel nozzles." The corresponding ISTS requirement (LCO Note) contains a provision that limits the applicability of the CTS allowances. The ISTS limitation states "provided no operations are permitted that would cause introduction into the Reactor Coolant System, coolant with boron concentration less than required to meet the minimum required boron concentration of LCO 3.9.1." The CTS is revised to incorporate the ISTS limitation. This changes the CTS allowance by prohibiting operations that will cause introduction into the RCS, coolant with a boron concentration less than required to meet the boron concentration of LCO 3.9.1. LCO Notes Actions b & c ITS 3.9.4 CTS 3.9.8.1 M.3 CTS 4.9.8.1 requires that an RHR loop be verified in operation and circulating a specified flow only in certain circumstances (i.e., during dilution and reduced inventory operations).

The corresponding ITS 3.9.4 also requires that the RHR loop be operable. The CTS LCO is revised to conform to the ITS LCO. This changes the CTS LCO by adding the requirement for the RHR loop to be operable as well as in operation.
LCO LCO ITS 3.9.5 CTS 3.9.8.2 M.1 CTS 3.9.8.2 requires two independent RHR loops to be OPERABLE and at least one loop to be in operation. The corresponding ISTS specifies a surveillance that requires verification every seven days of correct breaker alignment and indicated power available to the RHR pump not in operation. The CTS does not have a corresponding surveillance. The CTS is revised to adopt the ITS SR 3.9.5.2 for the standby RHR pump. This changes the CTS by adding a new Surveillance Requirement.
