LA.3 CTS 3.4.10. and Figure 3.4.101. detail various power-to-flow operating regions for the reactor core: CTS Actions a, b. and c specify requirements for operation in these regions: and N l l CTS 4.4.10.2 details the specific region to monitor for N, J instability when operating near the instability region. These ej ] controls are based on Generic Letter 94 02. "Long Term Solutions 3 and Upgrade of Interim Operating Recommendations for Thermal-Hydraulic Instabilities in Boiling Water Reactors" and the June 1994 BWROG Letter (no. 94078). ITS 3.4.1 maintains the scope and intent of CTS requirements and Actions, but relocates the definition of what constitutes core thermal hydraulic instability. # and the Figure that contains the definitions of the various regions, to the ITS Bases. Bases revisions require change control in accordance with ITS 5.5.10. Bases Control Program. These g l j relocations continue to provide adequate protection of the public ! health and safety since the ITS retain sufficient requirements ! related to maintaining appropriate response to thermal hydraulic l instabilities.

L.1 CTS 3.4.1.3 Applicability applies the recirculation pump speed , (revised to " loop flow" in another discussion) mismatch "during two recirculation loop operation." ITS SR 3.4.1.2 also applies the mismatch criteria to "when both recirculation loops [are] in operation": but adds a Note to the SR allowing 24 hours after establishing both loops in operation before the SR is required to be performed. This allowance is necessary to avoid intentional entry into the Actions each time the second recirculation pump is started and the SR has not been performed within its required Frequency. This change, although less restrictive. will have a negligible impact on safety. 1 l l l FERMI - UNIT 2 4 REVISION 4 04/02/99l

SRVs B 3.4.3 BASES SURVEILLANCE REQUIREMENTS (continued) The SR gives set pressures for all 15 SRVs installed. However. since only 11 SRVs are required, the SR is met if 11 SRVs are set properly. The Frequency is required by the Inservice Testing Program and is consistent with the. fact that Surveillance must be performed during shutdown conditions. SR 3.4:3.2 A manual actuation of each required SRV is performed to verify that, mechanically, the valve is functioning properly and no blockage exists in the valve discharge line. This can be demonstrated by the response of the turbine control valves or bypass valves, by a change in the measured steam flow, or by any other method suitable to verify steam flow. . Adequate reactor steam dome pressure must be available to l perform this test to avoid damaging the valve. Also, adequate steam flow must be passing through the main turbine or turbine bypass valves to continue to control reactor pressure when the SRVs divert steam flow upon opening. Sufficient time is therefore allowed after the required , pressure and flow are achieved to perform this test. l Adequate pressure at which this test is to be performed is !
= 850 psig (the pressure recommended by the valve manufacturer). Adequate steam flow is represented by I turbine bypass valves open at least 20%. Plant startup is allowed prior to >erforming this test because valve OPERABILITY and tie setpoints for overpressure protection are verified, per ASME Code requirements, prior to valve l installation. Therefore, this SR is modified by a Note that i states the Surveillance is not required to be performed !
until 12 hours after reactor steam pressure and flow are adequate to perform the test. The 12 hours allowed for manual actuation after the required pressure is reached is sufficient to achieve stable conditions for testing and provides a reasonable time to complete the SR. 'If a valve ' fails to actuate due only to the failure of the solenoid but is capable of opening on overpressure, the safety function of the SRV is considered OPERABLE.

DISCUSSION OF CHANGES ITS: SECTION 3.4.3 - SAFETY RELIEF VALVES (SRVs) LA.2 CTS 3.4.2.1.c and 4.4.2.1.1 requires the SRV position indicators be Operable. Additionally CTS 4.4.2.1.1 requires the SRV position indicators be demonstrated Operable with the pressure setpoint of each of the tail-pipe pressure switches verified by performance of a Channel Calibration. The SRV position indicators 4 do not impact the Operability of the SRVs. ' DECO knows of no plant specific reason that these position indicators would meet the 10 1 J 1 CFR 50.36 criteria for inclusion in the ITS. ITS 3.4.3 requires the Operability of the SRVs. but does not require that the j position indicators are Operable. Therefore these requirements , will be relocated to the Technical Requirements Manual (TRM). l ,4 which require revisions to be controlled by 10 CFR 50.59. This 4 relocation continues to provide adequate protection of the public
- E health and safety since the requirement for SRV Operability 4 continues to be required by the Technical Specifications, and is consistent with the NUREG 1433.
LR.1 CTS SR 4.4.2.1.2 requires 1/2 of the SRVs to be set pressure tested at least once per 18 months, such that all 15 SRVs are set pressure tested at least once per 40 months. These requirements
-. are considered details of methods for performing the surveillance
- and are not included in the ITS. These details do not impact the Operability of the SRVs. ITS 3.4.3 continues to require the Operability of the SRVs and requires they be tested in accordance with the IST Program. Regulatory control of changes to these requirements (e.g.. Technical Specification amendment or 10 CFR 50.59) is not necessary to provide adequate protection of the public health and safety since the requirement for SRV Operability continues to be required by the Technical Specifications. This is consistent with the NUREG 1433.

. Specifications (ITS), certain wording pref.erences or conventions are adopted which do not result in technical changes (either actual or interpretational). Editorial changes, reformatting, and revised numbering are adopted to make the ITS consistent with the Boiling Water Reactor (BWR) Standard Technical Specifications NUREG 1433. Rev. 1.
A.2 CTS 3.4.3.2.c snd 3.4.3.2.e allow Leakage to be averaged over "any 24 hour period." ITS 3.4.4.c and 3.4.4.d specifies that the Leakage is averaged over the " previous 24 hour period." The intent of the CTS is that the total Leakage limit applies, to the Q previous 24 hours (not any future or past 24 hour periods). This _ results in a " rolling average" covering "any 24 hour period." Therefore, changing "any" to "the previous" does not change the Q intent of the CTS requirement.

ITS SR 3.4.4.1 requires the performance of the Surveillance, but does not provide specific details on the ways the Surveillance can be performed. Defining the method used to determine RCS Leakage is not necessary to ensure Leakage does not exceed the LC0 limits and detect a degradation of the RCPB does not impact the requirement to maintain .the RCPB Leakage within specified limits. Therefore, these details can be relocated to the Bases. This change is consistent with NUREG-1433. The information moved to the Bases l

" Specific" L.1 CTS 4.4.3.2.1 requires that leakage be demonstrated to be within limit, in part, by monitoring primary containment atmospheric gaseous radioactivity be monitored at least once per 4 hours. .
However, the remaining parts of CTS 4.3.2.1 require leakage o~ e demonstrated to be within limit by monitoring once per 12 hours; and this 12 hour monitoring is done on the system that actually quantifies the leakage (the atmospheric gaseous radioactivity monitor is agt utilized to quantify the leakage for comparison to the LC0 limit, as provided in CTS footnote
- to the referenced surveillance).. ITS SR 3.4.4.1 requires verification every 12 hours that the RCS unidentified and total Leakage, and unidentified Leakage increase, are within limits consistent with lgg these latter CTS requirements. RCS Leakage is monitored by a l4 variety of instruments designed to provide alarms when excessive %
Leakage is indicated and to quantify the various types of Leakage. In conjunction with alarms and administrative controls, a 12 hour Q Frequency for this Surveillance is appropriate for identifying ; Leakage and for tracking trends. Note also that in Mode 1 this Frequency is restricted from applying the 25% extension of ITS j SR 3.0.2. This change is consistent with Generic Letter 88 01, ' will provide an effective means to determine any adverse trends and will have a negligible impact on safety. I l b 1 q

DISCUSSION OF CHANGES ITS: SECTION 3.4.4 RCS OPERATIONAL LEAKAGE I L.2 CTS 3.4.3.2.f. Action f. 4.4.3.2.1.b and 4.4.3.2.1.c contain requirements for Unidentified Leakage during Operational Conditions 2 and 3. IT5 3.4.4 revises the unidentified Leakage rate increase limit to be applicable only in Mode 1. instead of ' l the CTS required Operational Conditions 1. 2 and 3. As the plant starts up and increases pressure, increasing leakage will occur due to increasing pressure. This could result in a requirement for a unit shutdown. even though there is no new leakage source l with potential of rapid propagation. This change allows the limit to be applied only after Mode 1 is achieved, which is when reactor pressure has effectively reached normal operating pressure. The overall 5 gpm unidentified Leakage limit is still required to be 1 met during the startup. This limit is much below the expected l flow from a critical crack in the primary system. and provides l adequate protection during the brief exception to the leakage increase limit. This change is also consistent with NUREG 1433. Therefore, this less restrictive change will have a minimal impact on safety. As discussed in 00C L.1 above, the 12 hour Frequency for monitoring for RCS Leakage is adequate. The CTS 4.4.3.2.1.b and c frequency of once per 4 hours in MODES 2 and 3 is related to h the appropriate monitoring frequency for the unidentified leakage j rate increase limit, which is eliminated for MODE 2 and 3 (as discussed in this L.2 DOC). As such, this once per 4 hour frequency can be elk nated, leaving the once per 12 hour surveillance. RELOCATED SPECIFICATIONS None TECHNICAL SPECIFICATION BASES The CTS Bases for this Specification have been replaced by Bases that reflect the format and applicable content of ITS 3.4.4 consistent with the BWR STS.

[ c3[ , p lf l DISCUSSION OF CHANGES l ITS: SECTION 3.4.5 - RCS PRESSURE ISOLATION VALVE (PIV) LEAKAGE 1 CTS 3.4.3.2 Action d 4.4.3.2.3, and Table 3.4.3.2-2 contain i 3 LR.1 Actions, Surveillance details, and a specific list of PIV leakage d pressure monitors related to alarm only functions, which are 4 removed from Technical Specifications. These alarm only functions lg are not assumed in any accident analysis. Alarm only functions do not relate directly to the Operability requirements for the Reactor Coolant System. ITS does not specify indication only, alarm-only, or test equipment to be Operable to support Operability of a system or component. Additionally, DECO knows of 9-no Fermi-specific reason these monitors would be required to be 1 retained. Regulatory control of changes to these requirements @- (e.g., Technical Specification amendment or 10 CFR 50.59) is not necessary to provide adequate protection of the public health and safety since alarm-only functions do not relate directly to the Operability requirements for the system or analysis assumptions and the requirement for RCS and PIV leakage limits continues to be required by the Technical Specifications. LR.2 CTS 4.4.3.2.2.b requires that any time the leakage rate of a PIV is affected by maintenance, repair, or replacement, post niaintenance testing is required to demonstrate Operability of the PIV. ITS requires the PIV Operability, but does not direct the performance of testing when reoair activities have been performed. The requirement to perform post msintenance testing is applicable to all plant equipment. The majority of CTS LCOs do not contain this requirement to perform post maintenance testing although this requirement is applicable. Therefore, these post maintenance 4 i testing requirement details can be removed from Technical 6 Specifications consistent with NUREG 1433. Regulatory control of g changes to these requirements (e.g., Technical Specification amendment or 10 CFR 50.59) is not necessary to. provide adequate ! protection of the public health and safety since the requirement l for PIV Operability continues to be required by the Technical Specifications.

. l DISCUSSION OF CHANGES ITS: SECTION 3.4.6 - RCS LEAKAGE DETECTION INSTRUMENTATION NUREG-1433. The information moved to the Bases requires changes to be controlled in accordance with the ITS 5.5.10. Bases Control Program. This relocation continues to provide adequate protection of the public health and safety since the requirement for RCS leakage detection system Operability continues to be required by the Technical Specifications.
LA.2 CTS 3.4.3.1.b.2 requires operationai requirements for The drywell equipment drain sump level, flow and pump-run time system." which is utilized for monitoring identified leakage rates. ITS 3.4.6 contains only requirements related to meeting Regulatory Guide 1.45 for unidentified leakage. Based on comparison to the ? Technical Specification " split" criteria of 10 CFR 50.36(c)(2)(ii) 9 the drywell equipment drain system will be relocated to the ! l[ I Technical "equirements Manual (TRM), which require revisions to be Q controlled by 10 CFR 50.59. The drywell equi'pment drain sump level, flow and pump run time system is not a part of a primary success path in the mitigation of a DBA or transient. and is a non-significant risk contributor to core damage frequency and offsite releases. This relocation continue to provide adequate protection of the public health and safety since the ITS retain sufficient requirements related to controlling the magnitude of the identified leakage rate. TECHNICAL CHANGES - LESS RESTRICTIVE
Speci fi c" L.1 CTS 3.4.3.1 Action requires two leakage detection systems to remain Operable when allowing a 30-day restoration time. ITS Action statements are provided whigh allow unlimited continued operation with either required primary containment atmosphere 1 gaseous radioactivity monitor or drywell floor drain sump level monitoring system inoperable. In either case the primary system '
for identifying and quantifying unidentified leakage in the i containment (i.e., the drywell floor drain sump flow monitoring system) remains OPERABLE. Since the inoperable system (s) provide actions for more frequent leakage measurements (ITS 3.4.6 Required Actions B.1 and/or C.1), operation is alloed to continue with the h system (s) inoperable. However. with both backup systems inormble, this continued operation is limited to 30 days since the diversity is significantly reduced. t FERMI UNIT 2 2 REVISION 4 04/02/99l

r-DISCUSSION OF CHANGES ITS: SECTION 3.4.7 - RCS SPECIFIC ACTIVITY i ! ADMINISTRATIVE A.1 In the conver'sion of the Fermi 2 current Technical Specifications (CTS) to the proposed plant specific Improved Technical Specific'ations (ITS), certain wording preferences or conventions are adopted which do not result in technical changes (either actual or. interpretational). Editorial changes, ref.ormatting; and. revised numbering are adopted to make the ITS consistent with the Boiling Water Reactor (BWR) Standard Technical Specifications NUREG 1433. Rev. 1. in A.2 (Not used.) lig A.' 3 CTS Table 4.4.51 Item 5. requires " Isotopic Analysis of an Offgas Sample. " ITS 3.4.7 does not retain this requirement. This is acceptable because the CTS requirement is the same as ITS SR 3.7.5.1 which requires the same sample to be.taken every 31 days. Therefore, this is an administrative change with no impact on i safety because it only eliminates a duplicate requirement I contained in CTS.

The CTS Bases state that the intent of the requirement to limit the specific activity of the reactor k coolant is to ensure that whole body and thyroid doses at the site boundary would not exceed a small fraction of the limits stated in 10 CFR 100 (i.e.,10% of 25 rem and 300 rem. respectively) in the event of a main steam line failure outside containment or an instrument line break. To ensure that offsite thyroid doses do not exceed 30' rem. reactor coolant dose equivalent I 131-(DEI) is limited to less than or equal to 0.2 pCi/gm. CTS also limits reactor coolant gross specific activity to less than or equal to 100/E bar pCi/gm to ensure that whole body doses do not exceed 2.5 rem.

Elimination of CTS LC0 3.4.5.b and i Surveillance Items 1 and 3 of Table 4.4.5-1 will allow plant personnel to focus attention on efficient. safe operation of the g plant without the unnecessary distraction of the redundant Surveillance Requirement. Additional assurance that the offsite doses will not exceed a small fraction of the 10 CFR 100 limits is provided by increasing the frequency of sampling and analysis of the reactor coolant for DEI from at least once per 31 days to at least once per 7 days. Since (1) the reactor coolant limit on DEI adequately assures that offsite doses will not exceed small fractio.ns of the limits of 10 CFR 100 in the event of a main steam line failure outside containment and (2) gross gamma radioactivity rate of the noble gases measured at the condenser evacuation system pretreatment monitor station is limited by ITS 3.7.5 to a value that provides reasonable assurance the reactor coolant gross specific activity is maintained at a sufficiently low level to preclude offsite doses from exceeding a small fraction of the limits of 10 CFR 100, t the requirements associated with LC0 3.4.5.b and Surveillance 4 Items 1 and 3 of Table 4.4.5-1 are unnecessary. The associated Actions and Surveillance Requirements are also being deleted. consistent with the LC0 requirement deletion. L.2 CTS 3.4.5 Applicability includes Operational Condition 2. 3. and
- 4. ITS 3.4.7 Applicability is limited to only those conditions which represent a potential for release of significant quantities of radioactive coolant to the environment. Mode 4 is omitted since the reactor is not pressurized and the potential for leakage is significantly reduced. In Modes 2 and 3, with the main steam lines isolated, no escape path exists .for significant releases and requiremencs for limiting the specific activity are not required.
The Required Actions are also modified to reflect the new Applicabi.ity, and an option for exiting the applicable Modes is provided for cases where isolation is not desired. Based on the fact that the ITS Applicability is consistent with plant conditions where event consequences are significant, this less restrictive change will have a negligible impact on safety. 7 FERMI - UNIT 2 3 REVISION 4 04/02/99l
l DISCUSSION OF CHANGES I ITS: SECTION 3.4.7 - RCS SPECIFIC ACTIVITY L.3 CTS 3.4.5 Actions do not allow Mode changes while Dose Equivalent I-131 is not within limit (CTS 3.0.4). ITS 3.4.7 Action A ! provides a Note to the Required Actions to indicate that LC0 3.0.4 is not applicable. Entry into the applicable Modes should not be restricted due to the significant conservatism incorporated into the specific activity limit the low probability of an event which is limiting due to exceeding this limit, and the ability to restore transient specific activity excursions while the plant remains at, or proceeds to power operation. Therefore, operation during the allowed time frame would not represent a significant impact to the health and safety of the public. This less restrictive change will have a negligible impact on safety. I L.4 CTS 3.4.5 Action c requires increased sampling of Item 4b of CTS Table 4.4.5-1. CTS 3.4.5 Action c associates this sampling with changing plant conditions. However, as required by CTS 3.0.1 8 l i this Action applies only when the LC0 is not met. Similarly. CTS s 3.4.5 Act.on b requires the sampling of Item 4a of Table 4.4.5-1 when the LC0 is not met. Since sampling of Item 4a provides D sampling requirements equivalent to Item 4b. the Action c $ requirement (and associated Item 4b) are unnecessary. Therefore, s elimination of the duplicative requirements of CTS Action c (including associated footnote *) involves no impact on safety.

Detroit Edison has evaluated the proposed Technical. Specification change identified as "Less Restrictive" in accordance with the criteria specified by 10 CFR 50.92 and has determined that the proposed change does not involve a significart hazards consideration. The bases fe the determination that the proposed change does not involve' a significant hazards consideration is an evaluation of these changes against ; each of the criteria in 10 CFR 50.92. The criteria and the conclusions of the j evaluation are presented below.
- 1. Does the change involve a significant increase in 'the probability or consequences of an accident previously evaluated?
The proposed change eliminates the requirements for increased sampling of isotopic analysis for iodine (which is stated in terms of changing plant conditions. but required only by CTS 3.4.5 Action c and thus applicable only when the associated LC0 is not met). Equivalent sampling requirements, also applicable when the LC0 is not met, are g included in CTS Action b. The removal of an action covered by an , equivalent action is not considered as an initiator of any previously Q l evaluated accident, nor will it have any impact on the consequences of N ! any previously evaluated accident. Therefore, the proposed change will ; not increase the probability of any accident previously evaluated and ' will not increase the consequences of any accident previously evaluated.
- 2. Does the change create the possibility of a new or different kind of j accident from any accident previously evaluated? i The proposed change does not introduce a mode of plant operation, not '
previously analyzed, and does not involve a physical modification to the plant. Therefore it does not create the possibility of a new or different kind of accident from any accident previously evaluated. ,
- 3. Does this change involve a significant reduction in a margin of safety? i This change does not involve a significant reduction in a margin of safety si' ice no limitation, operating parameter, or analysis assumption
,- is modified. Therefore, no question of safety is involved and these changes do not involve any reduction in a margin of safety. FERMI - UNIT 2 7 REVISION 4 04/02/99

A.2 CTS 3.4.1.4.a. 3.4.1.4.b. and 4.4.1.1.4.b and c address a 50*F limitation between the idle. loop and either the " reactor coolant" or an " operating recirculation loop." ITS SR 3.4.10.4 and SR 3.4.10.6 presents these limitations together with the idle loop compared to "RPV coolant temperature." Since the operating loop temperature is cnnsidered synonymous with RPV coolant temperature. this change is considered an editorial presentation preference. As such, the stated requirements for "both loops have been idle" Q (CTS 3.4.1.4.a) and for "only one loop has been idle" (CTS % 3.4.1.4.b) will be the same and separate discussion is no longer Q necessary. Th.ese will be combined in ITS SR 3.4.10.4. % A.3 CTS 3.4.1.4 Action requires " suspend startup of any idle recirculation loop" if any required differential temperature is not within limit. ITS SRs 3.4.10.3 and 3.4.10.4 present the same required differential temperatures. however, with the requirement . that SRs be met (ITS SR 3.0.1) the action to preclude startup with unacceptable temperatures is inherent without an explicit action. @ Therefore, elimination of this CTS Action is an administrative presentation preference. A.4 CTS 3.4.6.1 Action for any out of limits condition requires
" restore...within 30 minutes." ITS 3.4.10 Required Action C.1 for Modes 4 and 5 states " initiate action to restore ... Immediately."
The CTS Action provides 30 minutes in which pressure and temperature requirements could exceed the limits, and if the parameters are incapable of being restored to within the limits within 30 minutes. provides no further action. The intent of the action is more appropriately presented in ITS Required Action C.1 which provides for tuilt inuous Actions during all out of-limits conditions in Mode 4 and 5. As an enhanced presentation of the CTS intent, the change is deemed to be administrative. FERMI UNIT 2 1 REVISION 4 04/02/991

Therefore, this change is an administrative change with no impact on safety. TECHNICAL CHANGES MORE RESTRICTIVE M.1 CTS 3.4.6.1 Action requires an evaluation to determine that the RCS remains acceptable for continued operation. -ITS imposes a specific limitation for the engineering evaluation with a specific completion time. The Completion Time of 72 hours is considered reasonable for operation in Modes 1. 2. and 3 (Required Action A.2) because the P/T. limits represent long term vessel fatigue and usage factors. In Modes 4 and 5. the Completion Time of "."rior.to entering MODE 2 or 3" (Required Action C.2) specifically gevents entry into operating Modes. This.is consistent with the CTS intent in applying LCO 3.0.4 The'open ended time limit on completing the evaluation when the unit is shutdown is a g reasonable interpretation of the CTS requirement, since it is not t expected that a P/T limit violation while shutdown would present - an immediate threat to the RCS integrity. As a specific limitation consistent with the NUREG. and an enhanced presentation ( of the CTS intent.. the change will' not introduce any adverse impact on safety.

NO SIGNIFICANT HAZARDS EVALUATION ITS: SECTION 3.4.11 - REACTOR STEAM DOME PRESSURE TECHNICAL CHANGES - LESS RESTRICTIVE (Soecification 3.4.11 "L.1" Labeled Comments / Discussions) Detroit Edison has evaluated the proposed Technical Specification change identified as "Less Restrictive" in accordance with the criteria specified by 10 CFR 50.92 and has determined that the proposed change does not involve a significant hazards consideration. The bases for the determination that the proposed change does not involve a significant hazards consideration is an evaluation of these changes against each of the criteria in 10 CFR 50.92. The criteria and the conclusions of the evaluation are presented below.
- 1. Does the change involve a significant increase in the probability or' consequences of an accident previously evaluated?
The proposed change resolves an obvious discontinuity between the LC0 statement and its surveillance, and the associated Action statement. The operating limit on reactor steam dome pressure is not considered as an initiator for any previously evaluated accident. Therefore, the-proposed change will not increase the probability of any accident previously evaluated. The difference is infinitesimal, and resolves an obvious discontinuity in o manner consistent with the Fermi-2 vessel ' overpressurization analyses and the CTS Action presentation. Therefore. the change will not significantly increase the consequences of any accident previously evaluated.
- 2. Does the change create the possibility of a new or different kind of l accident from any accident previously evaluated?
1 This proposed change will not involve any physical changes to plant systems, structures, or components (SSC), or measurable changes in normal plant operation. Therefore, this change will not create the possibility of a new or different kind of accident from any accident previously evaluated. l FERMI UNIT 2 1 REVISION 4 04/02/99 i _ - . I

The proposed change does not involve a significant reduction in a margin of safety because the change is consistent with the vessel overpressurization analysis assumptions.

SURVEILLANCE SR 3.9.7.1 REQUIREMENTS Proper functioning of the refueling position one-rod-out interlock requires the reactor mode switch to be in Refuel. During control rod withdrawal in MODE 5, improper positioning of the reactor mode switch could, in some instances, allow improper bypassing of required interlocks.

By " locking" the reactor mode switch in the proper position (i.e., removing the reactor mode switch key from the cons ~ ole while the reactor mode switch is positioned in refuel), an additional administrative control is in place to preclude operator errors from resulting in unanalyzed operation.

TE_CHNICAL CHANGES - LESS RESTRICTIVE
Speci fic" L.1 CTS 3.1.3.7 LC0 and Action b. an':' CTS 4.1.3.7. require the position indication system to indicate the current position of any withdrawn control rod in Mode 5. ITS 3.9.4 requires only ' full-in" position indication apability. This change is acceptable because the Operability of the control rod " full-in" position indication for each control rod (whether the control rod is inserted or withdrawn) is required to support Operability of the refueling interlocks (ITS 3.9.1) and Operability of the one rod-out interlock (ITS 3.9.2). Requiring only the " full-in" po:ition indication is acceptable because in Mode 5'the safety analysis is based on the assurance that interlocks ensure that either all or all but one control rod is fully inserted. There is no assumption lh in the safety analysis about rod position other than it is " full- '
in" or not " full in." Therefore, only the position indication channel associated with the " full in" indication is required to be Operable in Mode 5. ITS 3.9.4 modifies Surveillance Requirements to be consistent with the requirement that only the full-in indicator must be Operable. The new Surveillance (ITS SR 3.9.4.1) requires that each time a ; control rod is withdrawn from the full in position, the full-in indication is indicating correctly (i.e., it is not indicating full in when a control rod is withdrawn). (Note that failure to indicate " full in" when the control rod is fully inserted results in conservative actuation or the one rod out and refueling interlocks, and therefore, is not explicitly required to be verified.) Additionally, the current requirements to verify the position of the control rod every 24 hours (CTS 4.1.3.7.a). that the control rod position changes during exercise tests (CTS 4.1.3.7.b), and that the full out indicator functions during rod coupling checks (CTS 4.1.3.7.c). are deleted because these tests do not support Operability of the " full-in" position indication channel. These less restrictive changes have no impact on safety. RELOCATED SPECIFICATIONS None .q FERMI - UNIT 2 3 REVISION 4 04/02/99l
T NO SIGNIFICANT HAZARDS EVALUATION ITS: SECTION 3.9.4 CONTROL R00 POSITION INDICATION TECHNICAL CHANGES - LESS h 5fRICTIVE (Soecification 3.9.4 "L.1" Labeled Comments / Discussions) Detroit Edison has evaluated the proposed Technical Specification change identified as "Less Restrictive" in accordance with the criteria specified by 10 CFR 50.92 and has determined that the proposed change does not involve a l significant hazards consideration. The bases for the determination that the proposed change does not involve a significant hazards consideration is an evaluation of these changes against each of the criteria in 10 CFR 50.97. The criteria and the conclusions of the I evaluation are presented below.
- 1. Does the change involve a significant increase in the probability or consequences of an accident previously evaluated?
This change replaces a Mode 5 requirement that the position indication system indicate the current position of any withdrawn control rod with a requirement that only the control rod ~" full in" position indication is
> Operable for all control rods including those not withdrawn. This change will not result in an increase in the probability or consequences of an accident previously evaluated because the Operability of the control rod " full in" position indication for each control rod (whether the control rod is inserted or withdrawn) is sufficient to support Operability of the refueling interlocks and Operability of the one-rod-out interlock. Requiring Operability of the " full-in" position indication only is acceptable because in Mode 5 the safety analysis is based one on the control rodassurance that interlocks is fully inserted. There is ensure that either no assumption all or in the all but l@
safety analysis about rod position other than it is " full-in" or not " full-in." Therefore, only the position indication channel associated with the
" full in" indication is required to be Operable in Mode 5.
- 2. Does the change create the possibility of a new or different kind of accident from any accident previously evaluated?
This proposed change will not involve any physical changes to plant systems, structures. or components (SSC) nr changes in normal plant operation. Therefore, this change will not create the possibility of a new or different kind of accident from any accident previously

Additionally. each RHR shutdown cooling subsystem'is considered OPERABLE if it can be manually aligned (remote or local) in the shutdown cooling mode for removal of decay heat. Operation (either continuous or intermittent) of one subsystem can maintain and reduce the reactc" coolant temperature es required. However, to ensure adequate core flow to allow for accurate average reactor coolant temperature monitoring, nearly continuous operation of either an RHR pump or a recirculation pump is required.

DISCUSSION OF CHANGES ITS: SECTION 3.9.8 - RHR - LOW WATER LEVEL TECHNICAL CHANGES - LESS RESTRICTIVE
Generic"
- LA.1 CTS 3.9.11.2' includes details relating to system design, function.
. and Operability for the Residual Heat Removal System'in Shutdown Cooling Mode. ITS 3.9.8 includes only a requirement for Operability and moves details of system' design and specific Operability requirements to the Bases.' This is acceptable because the requirement to maintain the function Operable is not impacted by the relocation of the design information. Therefore, these details can be' adequately defined and controlled in the Bases which require change control-in accordance with ITS 5.5.10. Bases ,
Control Program. l LA.2 CTS 4.9.11.2.3 requires verification of RHR shutdown cooling capability. and includes details of the required capability. ITS ! SR 3.9.8.2 requires this same surveillance, but relocates the I details _ of RHR shutdown cooling capability to the Bases. This is acceptable because these details do not impact the ITS requirement ! to maintain the system Operable. These details can be adequately l c defined and controlled in the Bases which require change control
! in. accordance with ITS 5.5.10, Bases Control Program,- The system configuration and capability requirements are also described in the UFSAR. which are controlled in' accordance with 10 CFR 50.59.
LA.3 CTS 3.9.11.2 during Mode 5 operation with the reactor cavity not completely flooded requires reactor water level to be maintained 2 214 inches in addition to a means of forced circulation. CTS 3.9.11.2 Action c requires two means of forced circulation
~
from either two recirculation pumps or two RHR-SDC loops in the event 'evel is not maintained 2 214 inches. ITS 3.9.8 does not l retain these restrictions -- only requiring one means of forced circulation regardless of reactor water level. This is consistent with the NUREG 1433. This water level requirement can be adequately defined and controlled in the Technical Rec;uirements Manual (TRM), which requires revisions to be controlled by 10 CFR
'50.59. This relocation continues to provide adequate protection
> of the public health and safety 'since the requirement for forced circulation, and alternate means of reactor coolant circulation on loss of forced circulation, continues' to be required by the Technical Specifications.

SRVs B 3.4.3 1 BASES SURVEILLANCE REQUIREMENTS (continued) The SR gives set pressures for all 15 SRVs installed. However, since only 11 SRVs are required, the SR is met if 11 SRVs are set properly. The Frequency is required by the Inservice Testing Program and is consistent with the fact that Surveillance must be performed during shutdown conditions. SR 3.4.3.2 A manual actuation of each required SRV is performed to verify that, mechanically, the valve is functioning properly and no blockage exists in the valve discharge line. This can be demonstrated by the response of the turbine control valves or bypass valves, by a change in the measured steam flow, or by any other method suitable to verify steam flow. Adequate reactor steam dome pressure must be available to perform this test to avoid damaging the valve. Also, adequate steam flow must be passing through the main turbine or turbine bypass valves to continue to control reactor pressure when the SRVs divert steam flow upon opening. i Sufficient time is therefore allowed after the required pressure and flow are achieved to perform this test. Adequate pressure at which this test is to be performed is
= 850 psig (the pressure recommended by the valve manufacturer). Adequate steam flow is represented by l turbine bypass valves open at least 20%. Plant startup is allowed prior to performing this test because valve OPERABILITY and the setpoints for overpressure protection are verified, per ASME Code requirements, prior to valve installation. Therefore, this SR is modified by a Note that states the Surveillance is not required to be performed until 12 hours after reactor steam pressure and flow are adequate to perform the test. The 12 hours allowed for manual actuation after the required pressure is reached is sufficient to achieve stable conditions for testing and provides a reasonable time to complete the SR. If a valve fails to actuate due only to the failure of the solenoid but is capable of opening on overpressure, the safety function of the SRV is considered OPERABLE.

ACTIONS (continued) i Action is to restore either of the inoperable monitors to l OPERABLE status within 30 days to regain the intended leakage detection diversity. The 30 day Completion Time ensures that the plant will not be operated in a degraded ! configuration for a lengthy time period. ! E.1 and E.2 If any Required Action of Condition A, B, C, or D cannot be met within the associated Completion Time, the plant must be ! brought to a MODE in which the LC0 does not apply. To achieve this status, the plant must be brought to at least i MODE 3 within 12 hours and MODE 4 within 36 hours. The ! allowed Completion Times are reasonable, based on operating experience. to perform the actions in an orderly manner and without challenging plant systems. M ' With all required monitors inoperable, no required automatic means of monitoring LEAKAGE are available, and immediate plant shutdown in accordance with LCO 3.0.3 is required. SURVEILLANCE SR 3.4.6.1 REQlIIREMENTS This SR is for the performance of a CHANNEL CHECK of the required primary containment atmosphere gaseous radioactivity monitoring system. The check gives reasonable confidence that the channel is operating properly. The Frequency of 12. hours is based on instrument reliability and is reasonable for detecting off normal conditions. SR 3.4.6.2 This SR is for the po formance of a CHANNEL FUNCTIONAL TEST of the required RCS leakage detection instrumentation. The test ensures that the monitors can perform their function in l the desired manner. The Frequency of 31 days considers instrument reliability, and operating experience has shown it proper for detecting degradation. I FERMI UNIT 2 B 3.4.6 - 5 Revision 4, 04/02/99

SR 3.9.2.2 Performance of a CHANNEL FUNCTIONAL TEST demonstrates the associated refuel position one rod out interlock will ,
' function properly when a simulated or actual signal 1 indicative of a. required condition is injected into the logic. A successful test of the required contact (s) of a i channel relay may be performed by the verification of the l change .of state of a single contact of the relay. This A clarifies what is an acceptable CHANNEL FUNCTIONAL TEST of a WJ relay. This is acceptable because all of the other contacts of the relay are verified by other Technical Specifications and non Technical Specifications. tests at least once per refueling interval with applicable extensions. The CHANNEL FUNCTIONAL TEST may be performed by any series of .
sequential, overlapping, or total channel steps so that the entire channel is tested. The 7 day Frequency is considered adequate because of demonstrated circuit reliability, procedural controls on control rod withdrawals, and visual and audible indications available in the control room to alert the operator to control rods not fully inserted. To 1 perform the required testing, the applicable condition must I be entered'(i.e.. a control rod must be withdrawn from its 1 full in position). Therefore. SR 3.9.2.2 has been modified by-a Note that states the CHANNEL FUNCTIONAL TEST is not required to be performed until I hour after any control rod , is withdrawn. I REFERENCES 1. 10 CFR 50.

Control Rod OPERABILITY-Refueling B 3.9.5 l BASES LCO Each withdrawn control rod must be OPERABLE. The withdrawn control ' od is considered OPERABLE if the scram accumulator i pressure is = 940 psig and the control rod is capable of being automatically inserted upon receipt of a scram signal: however, no s)ecific scram time limit is imposed. Inserted control rods lave already completed their reactivity control function, and therefore are not required to be OPERABLE. l APPLICABILITY During MODE 5 withdrawn control rods must be OPERABLE to ensure that in a scram the control rods will insert and provide the required negative reactivity to maintain the d reactor subcritical. i o- For MODES 1 and 2. control rod requirements are found in fI LC0 3.1.2. " Reactivity Anomalies." LCO 3.1.3. " Control Rod _ OPERABILITY." LCO 3.1.4. " Control Rod Scram Times." and
< LC0 3.1.5 " Control Rod Scram Accumulators." During MODES 3 T and 4. control rods are not able to be withdrawn since the reactor mode switch is in shutdown and a control rod block is applied. This provides adequate requirements for control rod OPERABILITY during these conditions.
ACTIONS .A_J With one or more withdrawn control rods inoperable, action must be immediately initiated to fully insert the inoperable control rod (s). Inserting the control rod (s) ensures the shutdown and scram capabilities are not adversely affected. Actions must continue until the inoperable control rod (s) is fully inserted.

complete subsystem. l l Additionally. each RHR shutdown cooling subsystem is 1 considered OPERABLE if it can be manually aligned (remote or ! local).in the shutdown cooling mode for removal of decay heat. Operation (either continuous'or intermittent) of one subsystem can maintain and reduce the reactor coolant temperature as required. j g- APPLICABILITY One RHR shutdown cooling subsystem must be OPERABLE in i MODE 5, with irradiated fuel in the reactor pressure vessel.
$ with the water level = 20 ft 6 inches above the top of the g RPV flange. and heat losses to ambient not greater than or oc equal to heat input to the reactor coolant to provide decay heat removal. RHR System requirements in other MODES are covered by LCOs in Section 3.4. Reactor Coolant System (RCS): Section 3.5. Emergency Core Cooling Systems (ECCS) ' and Reactor Core Isolation Cooling (RCIC) System: and Section 3.6. Containment Systems. RHR Shutdown Cooling System requirements in MODE 5 with irradiated fuel in the h reactor 3ressure vessel and with the water level < 20 ft 6 inches a)ove the RPV flange are given in LC0 3.9.8.
4 ACTIONS A.,.1 With no RHR shutdown cooling subsystem OPERABLE. the availability of an alternate method of decay heat removal must be established within 1 hour. In this condition, the volume of water above the RPV flange provides adequate capability to remove decay heat from the reactor core. However, the overall reliability is reduced because loss of water level could result in reduced decay heat removal capability. The 1 hour Completion Time is based on decay > heat removal function and the probability of a loss of the available decay heat removal capabilities. Furthermore.

Additionally. each RHR shutdown cooling subsystem is ; considered OPERABLE if it can be manually aligned (remote or i local) in the shutdown cooling mode for removal of decay heat. Operation (either continuous or intermittent) of one subsystem can maintain and reduce the reactor coolant temperature as required. _However, to ensure adequate core flow to allow for accurate average reactor coolant tem)erature monitoring, nearly continuous operaticn of eitler an RHR pump or a recirculation pump is required. i Note 1 is provided to allow a 2 hour exception to shut down the operating subsystem every 8 hours. Note 2 is provided to allow a 2 hour exception for a single subsystem inoperability due to surveillance testing.
