This must be performed at a Frequency of 18 months. This SR is modified by a Note that requires the verification that time constants are adjusted to prescribed values. This changes the CTS by adding a CHANNEL CALIBRATION requirement for the Turbine Trip functions.

3.3.1 M.8 CTS Table 4.3-I contains a Surveillance Requirement for the Intermediate Range channels. A SR 3.3.1. II Table 4.3-1 Note CHANNEL CALIBRATION is required and modified by a footnote. Note i3 states, "The provisions 13 of Specification 4.0.4 are not applicable for entry in MODE 2 or I." ITS SR 3.3. 1.11 for the Intermediate Ranges requires a CHANNEL CALIBRATION every 18 months. This changes the CTS by deleting a portion of the Note reinstating the Speciflication 4.0.4 allowance.

Unit 2 CTS Table 4.3-I Function 18, Turbine Trip on Low Auto Stop Oil Pressure and Turbinc Stop Valve Closure, lists N/A under the "MODES IN WHICH SURVEILLANCE REQUIRED," column. Function 18 requires a CHANNEL FUNCTIONAL TEST to be performed for each portion of ihe function at a frequency of S/U (1). S/U requires the surveillance to be performed prior to each reactor start up. Note (1 states, "If not performed within the previous 31 days." The applicable MODES or other specified conditions for ITS Table 3.3.1-1 Function I1, RCP Breaker Position Trip is MODE I"), with SR 3.3. I. 14 as a required Surveillance.

Note (9) states, "Above the P-8 (Power Range Neutron Flux) interlock." This changes the CTS by requiring the surveillance for thi eRCP Breaker Position Trip and the Turbine Trip Functions to be performed in the ITS when they arc"not required in the CTS.

CTS Table 4.3-I Function 23.b Low Power Reactor Trip Block, P-7, states that a CHANNEL Table 3.3.1-1, Table 4.3-1 3.3.1 M.10 SR 3.3.1.5 CALIBRATION and a CHANNEL FUNCTIONAL TEST are to be perforrmed at a frcquency of R (refueling).

The CTS does not require a CHANNEL FUNCTIONAL TEST to be performed at any frequency. The ITS 3.3.2 Function for the start of the AFW pump on Loss of Offsite Power (6.d) requires the performance of SRs 3.3.2.8 (CHANNEL CALIBRATION) and 3.3.2.9 (ESFAS RESPONSE TIMES) every 18 months, and 3.3.2.6 (TADOT) every 92 days. The TADOT is modified by a Note that states, "Verification of relay setpoints not required." This changes the CTS by requiring the TADOT to be performed every 92 days.

3.3.2 M.7 CTS requirements in Table 3.3-3 list the Allowable Values for ESFAS Functions and Interlocks. The Table 3.3.2- 1 Table 3.3-3 Allowable Values for the following function are stated as: P-12 Ž_ 541 'F, Safety Injection (SI) on Containment Pressure High _<18.5 psia, SI on Pressurizer Pressure Low-Low > 1755 psig, SI on Steam Flow in Two Steam Lines Coincident with Tare Low-Low or Steam Line Pressure Low _ a AP corresponding to 44% of full steam flow increasing to 111.5% at full load, Containment Spray on Containment Pressure High-High < 29.25 psia, Steam Line Isolation on Containment Pressure Intermediate High-High < 19.3 psia, and Steam Line Isolation on Steam Flow in Two Steam Lines Coincident with Tve Low-Low or Steam Line Pressure Low < a AP corresponding to 44% of full steam flow increasing to 111.5% at full load.

This SR requires the performance of a TADOT at a frequency of once per reactor trip breaker (RTB) cycle. The SR is modified by a Note that states, "Verification of setpoint not required." The ITS TADOT and CTS CHANNEL FUNCTIONAL TEST requirements are equivalent. This changes the CTS by increasing the testing Frequency from once per refueling cycle to each time the reactor trip breaker is cycled.

The specification 3.0.4 exception allows MODE transitions while relying on the CTS 3.7.1.5 Action. ITS 3.7.2, Action C, applies with one or more MSTVs inoperable and does not allow operation in MODE I and does not provide an exception to ITS LCO 3.0.4, so MODE transition to MODE I is not allowed. This changes the CTS by not allowing operation in MODE I with an inoperable, closed MSTV.

None 3.7.1.5 Actions 3.7.2 M.4 CTS 3.7.1.5 ACTION for MODE I specifies that POWER OPERATION may continue when one MSTV is inoperable if the inoperable valve is restored to OPERABLE status or closed within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.

The ITS does not provide any allowance for continued operation by closing the valve while in MODE 1. This changes the CTS by deleting the allowance for continued operation in MODE I with a closed, inoperable MSTV.

CTS 3.7.1.5 Actions requires that when one main steam trip valve is inoperable in MODE I, the 3.7.2 Action A 3.7.1.5 Actions 3.7.2 M.5 valve is to be restored to Operable status within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> or the unit is to be in MODE 3 within the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

3.7.3 None 3.7.3 M. I CTS does not have any requirement for Main Feedwater Isolation Valves (MFIVs), Main Feedwater Pump Discharge Valves (MFPDVs), Main Feedwater Regulating Valves (MFRVs) and Main Feedwater Regulating Bypass Valves to be OPERABLE, other than a requirement for an actuation signal to be supplied to the valves in CTS 3.3.2.1. ITS 3.7.3 requires the MFIVs, MFPDVs, MFRVs, and MFRBVs be OPERABLE in MODES I, 2, and 3. This changes the CTS by incorporating the requirements of ITS 3.7.3.

3.7.4 None 3.7.4 M.1 CTS does not have any Technical Specification requirements for atmospheric dump valves. ITS 3.7.4 specifies the requirements for the "Steam Generator Power Operated Relief Valves,"

SGPORVs, consistent with the requirements of ISTS 3.7.4, "Atmospheric Dump Valves." This changes the CTS by incorporating the requirements of ITS 3.7.4.

Table M - More Restrictive Changes ITS Section 3.7 - Plant Systems DOC No. Description of Change ITS Requirement CTS Requirement 3.7.5 M. I CTS LCO 3.7.1.2 is applicable in Modes 1, 2, and 3. ITS LCO 3.7.5 is applicable in Modes 1, 2, 3.7.5 3.7.1.2 and 3, and MODE 4 when the steam generator is relied upon for heat removal for the system.

To support this change in the Applicability, the following additional requirements are added to the CTS:

"* A note is added to the LCO that requires an AFW train, supported by a motor driven pump, to be operable in MODE 4;

" A new ACTION E is added which requires an immediate action to restore a required inoperable AFW train to OPERABLE status when the SG is required in MODE 4; and

" The addition of Notes to ITS SRs 3.7.5.3 and 3.7.5.4. which state the requirements are not applicable in MODE 4 when a steam generator is reli d upon for heat removal.

3.7.6 M. I The CTS requirements on the ECST are applicable in MODES I, 2, and 3. ITS 3.7.6 is applicable 3.7.6 3.7.1.3 in MODES I, 2, and 3, and in addition, MODE 4 when a SG is relied upon for heat removal. Applicability Applicability Consistent with this change in applicability, the phrase "Be in MODE 4, without reliance on steam generator for heat removal" is added to ITS ACTION B. This changes the CTS requirements by requiring the ECST to be OPERABLE in MODE 4 when a SG is relied upon for heat removal.

3.7.6 M.2 CTS ACTION b requires the plant must be in HOT SHUTDOWN within the next twelve hours if the 3.7.6 Action B 3.7.1.3 Action b ECST is inoperable for seven days. ITS Action B states "Required Action and associated Completion

This changes the CTS to require the plant to be in MODE 3 within six hours. The change in the time to reach MODE 4 is discussed in DOC L. I.

3.7.7 M. I CTS Table 4.7-1 item #2 allows the sampling frequency for the DOSE EQUIVALENT 1-131 to be SR 3.7.7.1 Table 4.7-1, Item 2 extended to once per 6 months whenever the gross activity determination indicates the iodine concentrations are below 10% of the allowable limits. ITS SR 3.7.7.1 does not provide for this extended time frame for determining the DOSE EQUIVALENT 1-131 and requires verification of specific activity of the secondary coolant every 31 days whenever the unit is in MODES 1, 2, 3, and

4. This changes the CTS by deleting CTS Table 4.7-I, item 2.b, and the qualifying statement of, "whenever the gross activity determination indicates iodine concentrations greater than 10% of the allowable limit."

3.7.8 M. I CTS 4.7.4.1 does not contain a requirement to verify each SW System pump starts automatically on SR 3.7.8.3 None an actuation signal. ITS SR 3.7.8.3 states, "Verify each SW pump starts automatically on an actual or simulated actuation signal." This changes the CTS by adding a SR to test the SW Systems pumps.

ITS 3.7.l10 states, "The 3.7.10 3.7.7.1 following MCRIESGR EVS trains shall be OPERABLE: a. Two MCR/ESGR Emergency Ventilation System (EVS) trains; and b. One MCR/ESGR EVS train on the other unit." This changes CTS by specifying the number and type of MCRIESGR EVS trains required to be OPERABLE.

3.7.10 M.2 CTS 3.7.7.1 Action a states, "With either the emergency ventilation system or the bottled air 3.7. 10 Action A 3.7.7.1 Action a pressurization system inoperable, restore the inoperable system to OPERABLE status within 7 days..." ITS 3.7. 10 Condition A states, "One required LCO 3.7. I0.a or 3.7. 1 0.b MCRIESGR EVS train inoperable." ITS Required Action A. I states, "Restore train to OPERABLE status," within 7 days. This changes CTS by allowing only one required train of the MCR/ESGR EVS to be inoperable for 7 days, but not allowing the entire MCR/ESGR EVS to be inoperable for 7 days.

3.7.10 M.3 CTS 3.7.7.1 Action b states, "With both the emergency ventilation system and the bottled air 3.7.10 Actions B 3.7.7.1 Action b pressurization system inoperable, restore at least one of these systems to OPERABLE status within and C, LCO 3.0.3 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or be in at least HOT STANDBY 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 />."

The Bases for Required Action B.lI state, "During the period that the MCR/ESGR boundary is inoperable, appropriate compensatory measures (consistent with the intent of GDC 19) should be utilized to protect control room operators from potential hazards such as radioactive contamination. Preplanned measures should be available to address these concerns for intentional and unintentional entry into the condition." ITS 3.7.10 Condition C requires that if the Required Actions and associated Completion Time of Condition A or B are not met, the unit 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 />, and MODE 5 in 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.

This also changes CTS by requiring compensatory measures be taken while the MCR/ESGR boundary is inoperable. This results in allowing 23 fewer hours to place the unit in MODE 3 and MODE 5, and requires additional compensatory actions be taken.

ITS LCO 3.0.3 allows 7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br /> to place the unit in MODE 3, and 37 hours4.282407e-4 days <br />0.0103 hours <br />6.117725e-5 weeks <br />1.40785e-5 months <br /> to place the unit in MODE 5. This changes CTS by not providing a Completion time of 7 days when the two or more required MCR/ESGR EVS trains are inoperable resulting in less time allowed to place the unit in MODE 3 and MODE 5.

3.7.10 M.5 CTS 4.7.7.1 states, "Each control room emergency ventilation system shall be demonstrated SR 3.7.10.3 4.7.7.1 OPERABLE: ...d. At least once per 18 months by:...2. Verifying that the normal air supply and exhaust are automatically shutdown on a Safety Injection Actuation Test Signal." ITS SR 3.7.10.3 states, "Verify each LCO 3.7.10.a MCR/ESGR EVS train actuates on an actual or simulated actuation signal." The Frequency is every 18 months. This changes CTS by requiring verification of automatic actuation of each LCO 3.7.10.a MCR/ESGR EVS train on an actual or simulated actuation signal. The change moving details of how the test is performed are addressed in a removed detail discussion of change.

3.7.10 M.6 CTS 4.7.7. l.d.3 uses a reference of "outside atmosphere" with regard to the pressure at which the SR 3.7.10.4 4.7.7. l.d.3 emergency ventilation system must maintain the control room. ITS SR 3.7.10.4 uses the reference "adjacent areas." This changes the reference used when determining whether the MCR/ESGR envelope has been sufficiently pressurized to a more specific reference.

3.7.10 M.7 CTS 4.7.7.I.d.3 specifies positive pressure and flow requirements that must be met by the control SR 3.7.10.4 4.7.7. l.d.3 room emergency ventilation system. ITS SR 3.7.10.4 states the positive pressure and flow requirements that must be met by each required train of the MCRIESGR EVS. This changes the CTS by specifying that the each required train of the MCR/ESGR EVS must be capable of performing the specified Surveillance Requirement.

3.7.11 M.I ITS 3.7.11 Applicability includes, "During movement of recently irradiated fuel assemblies." ITS 3.7.11 None 3.7.11 Condition C is entered when the Required Action and associated Completion Time of Applicability and Condition A is not met during movement of recently irradiated fuel assemblies. The Required Actions Actions require either placing an OPERABLE MCRIESGR ACS subsystem in operation or suspending movement of recently irradiated fuel assemblies. Condition D is entered when less than 100% of the MCR/ESGR ACS cooling equivalent to a single OPERABLE MCR/ESGR ACS subsystem is available during movement of recently irradiated fuel. Required Action D. I requires suspending movement of recently irradiated fuel assemblies immediately. This changes CTS by adding an additional Applicability criteria and associated Conditions and Required Actions.

ITS SR 3.7. 11.1 states, "Verify each MCR/ESGR ACS chiller has the capability to remove the design heat load." The Frequency is every 18 months on a STAGGERED TEST BASIS. This changes CTS by replacing a temperature verification with a test to verify each MCR/ESGR ACS chiller has the capability to remove the design heat load.

3.7.11 M.3 CTS 3.7.7.1 Action d states, "With both the air conditioning systems inoperable, restore at least one 3.7.11 Action E 3.7.7.1 Action d system to OPERABLE status within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or be in at least HOT STANDBY within the next 6 and LCO 3.0.3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-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 />."

The change in the criteria for the systems is addressed in another more restrictive discussion of change.

3.7.12 M. I CTS LCO 3.7.8.1 states, "Two safeguards area ventilation systems (SAVS) shall be OPERABLE 3.7.12 and SRs 3.7.8.1 and 4.7.8.1 with: a. one SAVS exhaust fan b. one auxiliary building HEPA filter and charcoal adsorber 3.7.12.

ITS 3.7.12 states, "Two ECCS PREACS trains shall be OPERABLE." ITS Condition A addresses the inoperability of one ECCS PREACS train. ITS SR 3.7.12.1 and SR 3.7.12.2 require the respective surveillances be performed on each ECCS PREACS train. This changes CTS by applying the requirements to all the components that constitute an ECCS PREACS train, rather than just the SAVS.

I CTS 3.8.1. 1 Actions would allow the LCO to not be met for an indefinite period ofttime, as long as 3.8.1, Required 3.8.1. I Actions the allowed outage time of each individual Action is not exceeded. For example, an EDG may be Actions A.3 and inoperable for a period of 14 days. During the allowed time, an offsite circuit may become B.4 inoperable. This would require a 12-hour action to be entered, until cither the EDG or offisite circuit is restored to OPERABLE status. The restoration of either the EDG or offsite circuit is allowed within the CTS Actions for an unlimited period of time. This could allbw ihe LCO to not be met for a period that could exceed many weeks. ITS Required Actions A.3 and B.4 require the restoration of all required features within 17 days from discovery of failure to meet the LCO. This changes the CTS by limiting the total time that any combination of ot'tsite circuits and EDGs may be inoperable to a total of 17 days.

3.8.1 M.2 CTS requirement 4.8.1.1 .2 for the EDG day tank does not require a periodic surveillance to monitor SR 3.8.1.5 None the fuel oil tank for water. ITS SR 3.8.1.5 requires each EDG's day tank be checked and any accumulated water removed at a Frequency of every 92 days. This changes the CTS by adding an additional Surveillance Requirement.

3.8.I M.3 CTS Surveillance Requirement 4.8.1.1 .2.d.8 requires that the EDG must be capable of transferring SR 3.8.1.15 4.8.1.1 .2.d.8 loads to and from offsite electrical source. Once the capability has been demonstrated', in part c) the EDG may, "proceed through its shutdown sequence." ITS SR 3.8. 1.15 ,verifics the capability of the EDG to transfer loads from and to the offsite electrical source. The SR requires.in part c that the EDG, "Returns to ready-to-load operation." This changes the CTS by stating that the EDG is capable of re-powering the emergency bus by being returned to the ready-to-load condition.

3.8.1 M.4 CTS requirement 4.8.1.1.2.d.4 verifies that on an ESF signal without the loss of offsite power, the SR 3.8. 1.1 1 4.8.1 . 1.2.(..4 EDG starts in < 10 seconds with voltage > 3960 V and frequency > 59.5 Hz and operates in a standby condition > 5 minutes, The steady state voltage and frcquency are required to be > 3740 and

< 4580 volts and >Ž59,5 and

  • 60.5 Hz. ITS SR 3.8. 1.11 states the EDG will start in < 10 seconds with voltage > 3960 V and frequency > 59.5 Hz and operates in a standby condition _>5 minutes. The steady state voltage and frequency are required to be > 3740 to < 4580 volts and _>59.5 to
  • 60.5 lHz.

The ITS also requires verification that each permanently connected load rcmains cnergized from the offsite electrical power system and emergency loads are energized or auto-connecled through the sequencing timing relays are energized from the offlsite clectrical power system. This changes the CTS by requiring the verification of permanently connected loads and auto-connected loads, through their sequencing timing relays, remain energized from offisite circuits.

I ITS 5.1.1 states, "The plant manager or his designee shall approve, prior to implementation, each 5.5.1 None proposed test, experiment or modification to systems or equipment that affect nuclear safety." The CTS does not include such a statement. This changes the CTS by adding a required action for the plant manager or his designee.

5.0 M.2 ITS 5.4.1 states, "Written procedures shall be established, implemented, and maintained covering the 5.4.1 None following activities:...b. The emergency operating procedures required to implement the requirements of NUREG-0737 and NUREG-0737, Supplement 1, as stated in Generic Letter 82-33." The CTS does not include this requirement. This changes the CTS by adopting a new requirement for emergency operating procedures.

5.0 M.3 ITS 5.4.1 states, "Written procedures shall be established, implemented, and maintained covering the 5.4.1 None following activities:...e. All programs specified in Specification 5.5." The CTS does not include this requirement. This changes the CTS by adopting a new requirement for procedures to address programs described in ITS 5.5.

This changes the CTS by specifying certain information is required to be in the RWP or equivalent. The addition of the option to use a means equivalent to the RWP is addressed in DOC L. 16.

5.0 M.5 The CTS does not contain a diesel fuel oil testing program that controls the requirements for testing and 5.5.12 None maintaining the properties of both new and stored fuel oil. ITS 5.5.12 establishes a diesel fuel oil testing program to implement required testing of both new and stored fuel oil. This changes the CTS requirements by adding the requirement for a diesel fuel oil testing program.

5.0 M.6 The CTS does not contain specific requirements for a Technical Specification Bases Control Program 5.5.13 None that controls changes to the Bases. ITS 5.5.13 specifies the programmatic controls for processing changes to the Bases of the ITS. This changes the CTS by adding the requirements for the Technical Specification Bases Control Program.

ITS 5.6.6 also states, "The report shall outline the cause of the inoperability and the plans and schedule for restoring the instrumentation channels of the Function to OPERABLE status."

The CTS do not include these requirements. This changes the CTS by requiring a report to be submitted within 14 days after entering Condition B of ITS 3.3.3 and specifying the contents of the report.

5.0 M. 10 CTS 6.9.1.9, "Annual Radiological Effluent Release Report," states, "A single submittal may be made 5.6.3 6.9.1.9 for a multiple unit station. The submittal should combine those sections that are common to all units at the station..." The ITS 5.6.3 Note replaces the word "should" with "shall." This changes the CTS by clarifying that when a single submittal is made for a multiple unit station, sections common to all units are to be combined.

ITS 5.5.11, Explosive Gas and Storage Tank Radioactivity Monitoring Program, include limits on hydrogen in addition to oxygen in the waste gas decay tanks, and requires the program address requirements specified in ITS 5,5.11. This changes the CTS by requiring a new program and specifying certain requirements the program must meet. Changes moving Actions and Surveillance Requirements to the TRM are addressed by DOC LA.7.

5.0 M. 12 CTS 6.2.4.1 states, "The Shift Technical Advisor shall serve in an advisory capacity to Shift Supervisor 5.2.2.f 6.2.4.1 on matters pertaining to the engineering aspects of assuring safe operation of the unit." ITS 5.2.2.f states, "An individual shall provide advisory technical support to the unit operations shift crew in the areas of thermal hydraulics, reactor engineering, and plant analysis with regard to the safe operation of the unit. This individual shall meet the qualifications specified by the Commission Policy Statement on Engineering Expertise on Shift," This changes the CTS by adding more detail to technical areas for which the STA is to provide support, and states that the STA will meet the qualifications specified by the Commission Policy Statement on Engineering Expertise on Shift.

Table M - More Restrictive Changes ITS Section 5.0 - Administrative Controls DOC No. Description of Changes ITS Requirement CTS Requirement 5.0 M. 13 Unit 2 CTS 6.12.1, High Radiation Area, "*," states, "Health Physics personnel or personnel escorted 5.7.2 6.12.1 and 6.12.2 by Health Physics personnel shall be exempt from the RWP issuance requirement during the performance of their assigned radiation protection duties, provided they comply with approved radiation protection procedures for entry into high radiation areas." Unit 2 CTS 6.12.1 applies for control of entry into high radiation areas in which the intensity of radiation is greater than 100 mrem/hr but less than 1000 mrem/hr. Unit 2 CTS 6.12.2 states that the requirements of 6.12.1 also apply to each high radiation area in which the intensity of radiation is greater than 1000 mrern/hr, but less than 500 rads/hr at one meter from a radiation source or any surface through which radiation penetrates. ITS 5.7.2, whose applicability is the same as Unit 2 CTS 6.12.2, does not include this allowance. This changes the CTS by deleting the exemption from the RWP issuance requirement for entering the high radiation areas addressed by Unit 2 CTS 6.12.2.

CTS 6.9.1.5.a requires, "A tabulation on an annual basis of the number of station, utility, and other 5.6.1 6.9.1.5.a 5.0 M. 14 personnel (including contractors) receiving exposures greater than 100 mreml/yr and their associated man rem exposure according to work and job functions." CTS 6.9.1.5.a also states, "In the aggregate, at least 80 percent of the total whole body dose received friom external sources should be assigned to specific major work functions." ITS 5.6.1 states, "A tabulation on an annual basis of the number of station, utility, and other personnel (including contractors), for whom monitoring was performed, receiving an annual deep dose equivalent > 100 mrems and the associated deep dose equivalent (reported in person-rein) according to work and job functions." ITS 5.6.1 also states, "In the aggregate, at least 80 percent of the total deep dose equivalent received from external sources should be assigned to specific major work functions." This changes the CTS by changing dose and exposure terminology to the more precise deep dose equivalent terms. It also changes the CTS by clarifying that the personnel for whom reporting is done are those for whom monitoring was performed.

Table M - More Restrictive Changes ITS Section 5.0 - Administrative Controls DOC No. Description of Changes ITS Requirement CTS Requirement 5.0 M. 15 CTS 6.2.l.d states, "The management position responsible for training of the operating staff and the 5.2. Ld 6.2.l.d and management position responsible for the quality assurance functions shall have sufficient organizational 6.2. I.e freedom including sufficient independence from cost and schedule when opposed to safety considerations." CTS 6.2. I.e states, "The management position responsible for health physics shall have direct access to that onsitc individual having responsibility for overall facility management. Health physics personnel shall have the authority to cease any work activity when worker safety is jeopardized or in the event of unnecessary personnel radiation exposures." ITS 5.2. I.d states, "The individuals who train the operating staff, carry out health physics, or perform quality assurance functions may report to the appropriate onsite manager; however, these individuals shall have sufficient organizational freedom to ensure their independence from operating pressures." This changes the CTS by stating that specified individuals, not just a particular manager, have sufficient organizational freedom and sufficient independence from operating pressures to perform their work. Also, rather than having access to particular managers, or the authority to cease work for reasons specified in the Specifications, the individuals have sufficient freedom to perform their work.

5.0 M. 16 CTS 6.12.l.b states that one of the optional criteria that allows entry into a high radiation area is, "A 5.7.l.e and 5.7.2.e 6.12. L.b radiation monitoring device which continuously integrates the radiation dose rate in the area and alarms when a preset integrated dose is received. Entry into such areas with this monitoring device may be made after the dose rate level in the area has been established and personnel have been made knowledgeable of them." ITS 5.7.l.e and ITS 5.7.2.e state, "Except for individuals qualified in radiation protection procedures, or personnel continuously escorted by such individuals, entry into such areas shall be made only after dose rates in the area have been determined and entry personnel are knowledgeable of them. These continuously escorted personnel will receive a pre-job briefing prior to entry into such areas. This dose rate determination, knowledge, and pre-job briefing does not require documentation prior to initial entry." This changes the CTS by expanding the requirement to apply to all the options for conditions allowing entry into a high radiation area, and adding the criteria that, "These continuously escorted personnel will receive a pre-job briefing prior to entry into such areas.

This dose rate determination, knowledge, and pre-job briefing does not require documentation prior to initial entry." The phrase, "Except for individuals qualified in radiation protection procedures, or personnel continuously escorted by such individuals," is addressed by DOC L. 17.

5.0 M. 17 One option allowed by CTS 6.12.2 for personnel to enter a high radiation area with radiation intensity 5.7.2 6.12.2 greater than 1000 mrem, but less than 500 rads/hr at one meter from a radiation source or any surface through which radiation penetrates, is to have, "A radiation monitoring device which continuously indicates the radiation dose rate in the area." ITS 5.7.2 does not include this allowance. This changes the CTS by deleting one of the acceptable means for providing personnel radiation exposure information.

Table M - More Restrictive Changes ITS Section 5.0 - Administrative Controls DOC No. Description of Changes ITS Requirement CTS Requirement 5.0 M.18 CTS Table 6.2-1 states, "Procedures will be established to insure that NRC policy statement guidelines 5.2.2.d Table 6.2-1 regarding work hours established for employees are followed." ITS 5.2.2.d states, "Administrative procedures shall be developed and implemented to limit working hours of personnel who perform safety related functions (e.g., licensed Senior Reactor Operators (SROs), licensed Reactor Operators (ROs),

health physicists, auxiliary operators, and key maintenance personnel). The controls shall include guidelines on working hours that ensure adequate shift coverage shall be maintained without routine heavy use of overtime. Any deviation from the above guidelines shall be authorized by the plant manager or the plant manager's designee, in accordance with approved administrative procedures, and with documentation of the basis for granting the deviation. Controls shall be included in the procedures to require a periodic independent review be conducted to ensure that excessive hours have not been assigned. Routine deviation from the working hour guidelines is not authorized." This changes the CTS by adding specific requirements for limiting work hours of personnel who perform safety related functions. The change not referencing the NRC policy statement guidelines regarding work hours is discussed in DOC L.24.

As part of one option for equipment required to enter a high radiation area as specified in ITS 5.7. I.d.4 5.7.1 .d.4 and 6.12. L.c 5.0 M. 19 and 5.7.2.d.3, the specifications require, "A self-reading dosimeter (e.g., pocket ionization chamber or 5.7.2.d.3 electronic dosimeter) and," one of two other criteria be met for entering a high radiation area. CTS 6.12.l.c does not include this requirement. This changes the CTS by adding an additional requirement for entering a high radiation area.

ITS 5.5.15.b states, "The containment design pressure is 45 psig." The CTS does not include such a 5.5.15.b None 5.0 M.20 statement. This changes the CTS by adding a design criterion to the Technical Specifications.

5.0 M.21 CTS 4.7.8. I provides ventilation filter testing requirements for the safeguards area ventilation systems 5.5.10 4.7.8.1 (SAVS). Each system is described as having one SAVS exhaust fan and one auxiliary building HEPA filter and charcoal adsorber assembly. ITS 5.5.10 provides ventilation filter testing requirements for the ECCS Pump Room Exhaust Air Cleanup System (PREACS) trains. Each ECCS PREACS train is described as having one safeguards area exhaust fan, one Auxiliary Euilding Central exhaust system fan, and respective filters, controls, and dampers. This changes CTS by adding additional equipment tested as part of the ventilation filter testing requirements, and changing the testing criteria accordingly, to conform to the system as described in NUREG- 1431.

Table M - More Restrictive Changes ITS Section 5.0 - Administrative Controls DOC No. Description of Changes ITS Requirement CTS Requirement 5.0 M.22 CTS 6.8.4.c, "Secondary Water Chemistry," requires, "A program for monitoring of secondary water 5.5.10 6.8.4.c chemistry to inhibit steam generator tube degradation." ITS 5.5.9, "Secondary Water Chemistry Program," states, "This program provides controls for monitoring secondary water chemistry to inhibit SG tube degradation and low pressure turbine disc stress corrosion cracking." This changes CTS by adding the fact that the Secondary Water Chemistry Program provides controls for monitoring secondary water chemistry to inhibit low pressure turbine disc stress corrosion cracking in addition to SG tube degradation.

5.0 M.23 Unit I CTS 6.12, High Radiation Area, footnote "*," states, "Health Physics personnel shall be exempt 5.7.1.c and 5.7.2.c 6.12 footnote "*"

from the RWP issuance requirement during the performance of their assigned radiation protection duties, provided they comply with approved radiation protection procedures for entry into high radiation areas." Unit 2 CTS 6.12, High Radiation Area, footnote "*," states, "Health Physics personnel or personnel escorted by Health Physics personnel shall be exempt from the RWP issuance requirement during the performance of their assigned radiation protection duties, provided they comply with approved radiation protection procedures for entry into high radiation areas." ITS 5.7.1.c states, "Individuals qualified in radiation protection procedures and personnel continuously escorted by such individuals may be exempted from the requirement for an RWP or equivalent while performing their assigned duties provided that they are otherwise following plant radiation protection procedures for entry to, exit from, and work in such areas." ITS 5.7.2.c states, "Individuals qualified in radiation protection procedures may be exempted from the requirement for an RWP or equivalent while performing radiation surveys in such areas provided that they are otherwise following plant radiation protection procedures for entry to, exit friom, and work in such areas." This changes the CTS by requiring that for personnel to be exempt from the RWP issuance requirement, they must be qualified in radiation protection procedures, or escorted by a qualified individual in high radiation areas. Changing the term "Health Physics" to "radiation protection" is addressed by DOC L. I I.

5.0 M.24 CTS Table 6.2-1 requires that with both units in MODE5 or 6 or defueled, two Auxiliary Operators 5.2.2.a Table 6.2-1 (AOs) be part of the staff manning, one AO assigned to each unit. ITS 5.2.2.a states, "Two unit siteg with both units shutdown or defueled require a total of three non-licensed operators for the two units."

This changes the CTS by requiring three AOs with both units shutdown or defueled. Other changes to the AO requirements are addressed by DOC L.9.

5.0 M.25 ITS 5.6.5.b contains two analytical methods, WCAP-8745-P-A and WCAP-14483-A, which do not appear 5.6.5.b None in the CTS. This changes the CTS by adding two analytical methods to those referenced in the Technical Specifications.

5.0 M.26 ITS 5.5.10.e requires testing of MCR/ESGR EVS heaters to verify they dissipate the required wattage. The 5.5. 1l0.e None CTS does not contain this requirement. This changes the CTS by adding a Surveillance Requirement.
