e DISCUSSION OF CHANGES ITS: SECTION 3.3.3.1. PAM INSTRUMENTATION A.5 CTS Table 4.3.7.5 1 footnote # states that the provisions of Specification 4.0.4 are not applicable. This is not required in ITS 3.3.3.1 because any potential confusion concerning when the surveillance is. required is eliminated by specifying the precise 7
requirements for performance of the Surveillance such that an explicit exception to 4.0.4 is not necessary. The ITS SR 3.3.3.1.2 Note 2 h
modifies the Frequency such that it is "Not required to be performed Q
until 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> for one channel and 7 days for the second channel after >
I 15% RTP." This is an administrative change with no impact on safety.
TECHNICAL CHA N C MORE RESTRICTIVE None TECHNICAL CHANGES - LESS RESTRICTIVE
" Generic" LR.1 CTS Table 3.3.7.5-1. Action 81, requires that with the Operable channels less than the minimum required, initiate the preplanned alternate method of monitoring the appropriate parameter (s) within "3
72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> and restore the inoperable channel within 7 days. ITS 3.3.3.1, Action C, requires the channel restored within 7 days, but does not require the preplanned alternate method of monitoring to be initiated within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. This is acceptable because the requirement to initiate an alternate monitoring plan does not impact the requirement to restore the channel within 7 days.
k Furthermore, the probability of an accident during the allowed s
repair time is minimal. Regulatory control of changes to this requirement (e.g., Technical Specification amendment or 10 CFR 50.59) is not necessary to provide adequate protection of the I
public health and safety since the requirement for post accident instrument channel Operability and actions for inoperable instrumentation, continues to be required by the Technical l
Specifications.

REVISION 14, 08/26/99l a
DISCUSSION OF CHANGES ITS: SECTION 3.3.4.1 - AWS-RPT INSTRUMENTATION A.4 For CTS Specification 3.3.4 (and ITS 3.3.4.1). the AWS RPT system instrumentation is interpreted to include the actuated device (s).
Each instrumentation channel (reactor water level and reactor pressure) ultimately provides signals that can result 1.n all four breakers tripping. Therefore, any inoperable breaker is s
necessarily associated with both trip systems being inoperable.
I For the case of an inoperable AWS-RPT breaker CTS 3.3.4 Action e does not allow inoperable channels to be placed in trip, but required both trip systems be restored or the plant to shutdown.
Due to the reformatting to ITS, where multiple Condition entry applies, and the ITS presentation of Action A for any number of inoperable channels, the ITS option for tripping channels must be
\\
taken exception to in order to conform to CTS requirements. Since l
ITS Action A can apply to one or many inoperable channels, the Note to Required Action A.2 is provided to direct a restoration requirement (and preclude a channel tripping allowance) in the event of an inoperable trip breaker. This explicit limitation is only a clarification of the requirements that would be imposed by C
compliance with CTS 3.3.4 requirements. The changes to the time 3
allowed to restore the inoperable breaker / channels are addressed by DOC L.1.
Therefore, this change only reflects a presentation
. _.y) clEffication necessitated by the ITS format.
~
~ ~~
A.5 CTS 4.3.4.2 requires an LSFT "and simulated automatic operation" of all channels. The simulated automatic operation is interpreted in the CTS to be included in the LSFT, since the CTS LSFT definition " includes the actuated device." ITS SR 3.3.4.1.4 n
O requires an LSFT but explicitly states " including breaker
]
actuation." Since the ITS LSFT definition is revised to exclude g
the actuated device (refer to Section 1.0), explicitly adding g
" breaker actuation" captures the CTS requirement. This clarification is an administrative presentation preference only.
A.6 CTS Table 3.3.41, Note (*), allows required surveillance testing "without placing the trip system of the tripped condition provided the other channel in the same trip function is OPERABLE." ITS SR Note 2 provides the same allowance stated as " entry into the associated Conditions and Required Actions may be delayed provided the associated Function maintains trip capability." This represents consistency in presentation with other Specifications, and as such, is considered an administrative change.

DISCUSSION OF CHANGES ITS: SECTION 3.3.5.1 - ECCS INSTRUMENTATION A.9 CTS 4.3.3.3 requires ECCS Response Time testing however, the
]
details of the testing acceptance criteria are located in the Technical Requirements Manual (TRM): outside of Technical Specifications. Since the ECCS response time acceptance criteria includes testing only the ECCS system response (and utilizing assumed values for the ECCS instrumentation response), the 1
required Surveillance is more appropriately required in the ECCS Specification, ITS 3.5.1.
This change is a presentation preference only with no technical change or change in intent.
Refer to Section 3.5 for further discussion of any changes from the CTS presentation.
A.10 CTS Table 3.3.31 Actions 30.a 31. and 33, as they apply to inoperable ADS actuation channels, result in options to declare 7
associated ADS Trip System inoperable.
(Note: refer to DOC L.1 D
for discussion of CTS change from declaring ECCS inoperable to declaring ADS trip system inoperable for CTS Action 30.a.).
The CTS actions would then transfer to Action c of CTS 3.3.3, and provide additional time for restoration.
ITS 3.3.5.1 Actions E l
and G combine these restoration times for clarity. Any technical m
changes are addressed in other discussions of change. The revised prEie'ntation preference is an administrative change with no impact on safety. { Note also that CTS Action 30.b (converted to ITS 7
Required Action E.1) does not transfer to CTS Action c for additional time; it declares the ADS valves inoperable and 3
transfers Actions to LCO 3.5.1.
The ITS 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> Completion Time of g
Required Action E.1 matches the CTS Action 30.b time, and the ITS g
RequiredActionG.1matchesthetransferofActionstoLC03.5.1.}
A.11 CTS 4.3.3.2 requires an 18 month LSFT of all ECCS Instrumentation channels (which would include ADS Manual Inhibit function). CTS Table 4.3.3.1-1. Item 4.1, also required an 18 month Channel Functional Test of the ADS manual Inhibit function.
ITS Table 3.3.5.11 only requires the LSFT (SR 3.3.5.1.5) for this a
function. The Channel Functional Test for this function is e
adequately encompassed by the LSFT performance. Eliminating a g
reference to performing a Channel Functional Test is therefore an oc administrative change that eliminates a duplicative test.

DISCUSSION OF CHANGES ITS: SECTION 3.3.5.1 - ECCS INSTRUMENTATION j
TECHNICAL CHANGES - MORE RESTRICTIVE M.1 CTS Table 3.3.31 Actions 30.a and 32 allow the trip system associated with inoperable channels to be tripped to comply with the required action, and thereby allowing continued operation.
ITS 3.3.5.1 Required Action C.2 does not allow this option: but rather requires that inoperable channels be restored to Operable status.
If inoperable channels are not restored ITS 3.3.5.1 Action G would be entered, requiring the associated ECCS features lk to be declared inoperable. The Functions associated with these required actions are functions that perform a dual role (where tripping the trip system would: 1) not be clear what direction to trip to, and 2) result in the affected system continuing to be in an inoperable state) or functions that would inappropriately start the affected system. Therefore, tripping the associated trip system is replaced with the more appropriate " restore channel to OPERABLE status" otherwise declare associated ECCS features inoperable.
M.2 CTS Table 3.3.31 Actions 31, 33, and 34 allow 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to restore inoperable channels, regardless of whether the associated HPCI or
_s _ _,
ADS function is inoperable in both hivisions (resulting in a~ loss ~
~~ ~
~
of that ECCS function). For certain specified inoperabilities n
that result in a loss of initiation function. ITS 3.3.5.1 Required d
Actions D.1 and F.1 (and associated Notes) provide a more lg restrictive time of "I hour from discovery of loss of [HPCI/ ADS]
v initiation capability" to restore or declare the associated ECCS function inoperable. This provides a more appropriate action that will not adversely impact safety.
M.3 CTS Table 3.3.31 Note (a), allows required surveillance testing which causes channels to be inoperable without taking Actions for inoperable channels "provided at least one OPERABLE channel in the same trip system is monitoring that parameter." ITS SR Note 2 provides the same intended allowance by stating " entry into the g
associated Conditions and Required Actions may be delayed for Functions other than 3.c and 3.f provided the associated Function l@
or redundant Function maintains ECCS initiation capability." In 3
the case of some trip Functions literal compliance with the CTS allowance may not ensure trip capability remains (i.e., a single channel that is monitoring the parameter will not produce an initiation signal: the logic is 2 out of 2). This represents a j
more restrictive change, which has no significant impact on safety.

DISCUSSION OF CHANGES ITS: SECTION 3.3.6.2 - SECONDARY CONTAINMENT ISOLATION INSTRUMENTATION TECHNICAL CHANGES - LESS RESTRICTIVE
Speci fic" L.1 CTS Table 3.3.2-1 and Table 4.3.2.1 1. Function 6.a. requires that the reactor vessel water level Function be Operable (in addition
' to other specified conditions) when handling irradiated fuel in the secondary containment and during Core Alterations.
ITS Table 3.3.6.2-1 Function 1 eliminates the handling fuel and Core Alterr, tion Applicabilities for the reactor vessel water level Function (but retains the other Applicabilities consistent with
{
the CTS). The reactor vessel low level Function only actuates in the event of a vessel draindown event (i.e., an event initiated as a result of an operation with a potential for draining the reactor i
vessel). Reactor vessel water level Function is not assumed to actuate to provide secondary isolation for any event that is postulated to occur during core alterations or fuel handling (which is performed with the reactor cavity flooded). Therefore, this is a less restrictive change with no impact on safety.
L.2 Inoperable secondary containment isolation instrumentation affects two aspects of Secondary Containment Integrity - the secondary containment isolation valves (SCIVs) and the standby gas treatment (SGT) system. CTS 3.3.2 Actions b.1 and c for inoperable secondary containment isolation instrumentation direct entry into CTS Table 3.3.2-1 Actions 24 and 27.
In the case of CTS 3.3.2 Action b.1 there is an allowance for a 6 hour6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> delay (changed to 12 or 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> in the ITS. see DOC LC.1) before taking Action 24 or
- 27. CTS Table 3.3.2-1. Action 24 for inoperable secondary j
containment isolation instrumentation, requires Secondary 4
Containment Integrity be established with the SGT system operating I
within one hour. Action 27 is similar, except that it provides an 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> allowar.ce to restore manual initiation capability (refer to DOC A.6 for a discussion of this allowance). Actions 24 and 27 are applicable at times when the Secondary Containment Integrity is already required by CTS 3.6.5.1.
Therefore, it is not necessary to explicitly repeat the requirement to establish Secondary Containment Integrity.

DISCUSSION OF CHANGES ITS: SECTION 3.3.6.2 - SECONDARY CONTAINMEN'T ISOLATION INSTRUMENTATION L.2 (continued)
If one secondary containment isolation instrumentation trip system is affected by the inoperable instrumentation (i.e., CTS 3.3.2 Action b.1), Secondary Containment Integrity would not be lost because the otbr trip system would still be available to close its SCIVs. In this case, the restoration of the SCIV portion of Secondary Containment Integrity would require no action for compliance with CTS 3.3.2 or ITS 3.3.6.2, and therefore no change is introduced. (Note however, the Actions for inoperable SCIVs would apply.) This aspect is discussed within this less restrictive change DOC for completeness.
If both trip systems were affected by the inoperable instronentation (i.e., CTS 3.3.2, Action c) Secondary Containment Integrity would be lost because both divisions of SCIVs would be affected. In this case, the CTS Table 3.3.2-1 actions would require establishing Secondary Containment Integrity within one hour, which for SCIVs is equivalent to ITS Required Action C.1.1 (e.g., Secondary Containment Integrity was affected by the 3
inoperable instrumentation resulting in a loss of isolation J
capability -- isolating the penetrations will restore it).
y i
ITS Required Action C.1.2 provides an alternative to isolating the k
If isolation capability is maintained k
j (i.e., at least one trip system has the minimum required channels l
operable), declaring the affected SCIVs inoperable would place you j
in ITS 3.6.4.2, Required Action A.1, which allows 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> to j
isolate the penetration. This is equivalent to the CTS since Secondary Containment Integrity would not be lost.
If isolation capability is lost (i.e., both trip systems affected), ITS 3.3.6.2. Required Action B allows I hour to restore isolation capability.
If this is not achieved, Required Action C.1.2 would allow declaring the affected SCIVs inoperable within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />.
ITS 3.6.4.2, Required Action B.1 would then allow 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> to isolate i
the affected penetrations for a total of 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> from the time the instrumentation was declared inoperable until the penetrations are isolated, restoring Secondary Containment Integrity. This less restrictive change (6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> versus 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />) is acceptable because of the relatively brief time involved, the minimal probability of an event during this time, and any remaining manual capabilities that remain to effect the isolation.

DISCUSSION OF CHANGES ITS: SECTION 3.3.6.2 - SECONDARY CONTAINMENT ISOLATION INSTRUMENTATION L.2 (continued)
As for the CTS requirement to establish SGT operating. CTS Table 3.3.2-1 Actions 24 and 27 require starting the affected SGT subsystem (s) within one hour.
ITS Required Action C.2.1 provides this same requirement. However, instead of starting the affected SGT subsystem (s), Required Action C.2.2 provides a less restrictive option to allow declaring the affected SGT subsystem (s) inoperable. The action to initiate the associated SGT subsystem is the compensatory action for losing the automatic initiation instrumentation for that subsystem. Taking that action i
allows for unlimited continued operation. Declaring the affected SGT subsystem (s) inoperable avoids placing the SGT subsystem (s) in operation but limits the time you are allowed to operate (7 days for one subsystem, immediate shutdown for two subsystems) under this provision. These actions are the same as the actions in CTS 3.6.5.3 for the SGT system. Under the CTS, if you take the g
actions in CTS 3.6.5.3 for inoperable SGT subsystem (s). Secondary tc Containment Integrity would be maintained. Therefore, under the CTS there would not be any additional action required to restore" Secondary Containment Integrity. Since there are accepted safe actions in the CTS for loss of a SGT subsystem function which still allow for the secondary containment to be considered
' TCi~
Operable. allowing these;same actions will continue to ensure-
-~
continued safe operation when the impact on the secondary containment function is solely due to instrumentation that effects the automatic start of SGT system. Therefore, this less restrictive change (not starting the affected SGT subsystem (s))
will have a negligible impact on safety.

9 LLS Instrumentation B 3.3.6.3
]
BASES APPLICABILITY The LLS instrumentation is recuired to be OPERABLE in KODES 1, 2, and 3 since consicerable energy is in the nuclear system and the SRVs may be needed to provide pressure relief. If the SRVs are needed.-then the LLS function is required to ensure that the primary containment design basis is maintained. In MODES 4 and 5. the reactor pressure is low enough that the overpressure limit cannot be a)proached by assumed operational transients or accidents.
T1us, LLS instrumentation and associated pressure relief is not required.
ACTIONS AJ The failure of any reactor steam done pressure instrument channel to provide the arming, SRV opening and closing pressure set)oints for an individual LLS valve does not affect the a)ility of the other LLS SRV to perform its LLS function. A LLS valve.is OPERABLE if the associated logic has one Function'l channel, two Function 2 channels, and at least three Function 3 channels OPERABLE. Therefore, 14
. _../.A_
days is provided to restore the inoperable channel (s) to OPERABLE status (Required Action A.1).
If the inoperable channel (s) cannot be restored to OPERABLE status within the allowable out of service time, Condition C must be entered and its Required Action taken. The Required Actions do not allow placing the channel in trip since this action could result in an instrumented LLS valve actuation. The 14 day Completion Time is considered a)propriate because of the redundancy in the design (two L.5 valves are provided and any one LLS valve can perform the LLS function) and the very low probability of multiple LLS instrumentation channel failures, which renders the remaining LLS SRV inoperable,
-p occurring together with an event requiring the LLS function during the 14 day Completion Time.
l B.1. B.2. and B.3 Although the LLS circuitry is designed so that operation of a single tailpi>e pressure switch will result in arming both LLS logics: eac1 tailpipe pressure switch provides an input to both LLS logics. Since any overpressure event will normally open at least five SRVs and actuate their associated pressure switch inputs, the LLS logic and
-instrumentation remains capable of performing its safety function even with several SRV tailpipe pressure switch

s OPERABLE status, prior to entering MODE 2 or 3 from MODE 4.
This will ensure that sufficient switches are OPERABLE at the beginning of a reactor startup (this is because the switches are not accessible during plant operation). The p
Required Actions do not allow placing the channel in trip since this action could result in an inadvertent LLS valve actuation. As noted. LCO 3.0.4 is not applicable. thus allowing entry into MODE 1 or 2 from MODE 2 or 3 with i
inoperable channels. This allowance is needed since the channels only have to be repaired prior to entering MODE 2 or MODE 3 from MODE 4.
A Note has been provided in the Condition to modify the Required Actions and Completion Times conventions related to LLS Function 3 channels. Section 1.3. Completion Times.
e specifies that once a Condition has been entered. subsequent O
divisions, subsystems, components, or variables expressed in the Condition discovered to be inoperable or not within g
limits, will not result in separate entry into the Condition. Section 1.3 also specifies that Required Actions of the Condition continue to apply for each additional failure, with Completion Times based on initial entry into the Condition. However, the Required Actions for inoperable LLS Function 3 channels provide appropriate compensatory f
measures for separate inoperable Condition entry for each SRV with inoperable tailpipe pressure switches.

DISCUSSION OF CHANGES ITS: SECTION 3.3.6.3 - LLS INSTRUMENTATION ADMINISTRATIVE A.1 In the conversion of the Fermi 2 current Technical Specifications (CTS) to the proposed plant specific Improved Technical Specifications (ITS), certain wording preferences 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 ITS 3.3.6.3 SR Note is included as a clarification of the ITS presentation of SRs: specifying that ITS Table 3.3.6.31 be referred to determine which SRs apply for each Function. As such, its inclusion is an administrative presentation preference.

iriitrumentation. The arming" instrumentation for the LLS Function (reactor pressure and SRV tail pipe pressure) is not addressed in the CTS requirements for the LLS Function. ITS Table 3.3.6.3 includes Function 1 and 3 for these arming" Functions. These additional requirements include Operability, Surveillance, and Action requirements.
In the case of the SRV tail-pipe arming Function, the ITS 3.3.6.3 Action B is provided, and is based on maintaining a high degree of reliability for the I
supporting function, while minimizing the potential for any unnecessary forced shutdown. Since opening any one of 15 SRVs l
will suffice to arm both LLS valves, the actions allow for continued operation with multiple inoperable tail pipe pressure 7s channels. The Actions include requirements to ensure that within

DISCUSSION OF CHANGES ITS: SECTION 5.7 - HIGH RADIATION AREA ADMINISTRATIVE A.1 In the conversion of the Fermi 2 current Technical Specifications (CTS) to the pre osed plant specific Improved Technical Specifications (.TS), certain wording preferences 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 6.12.1 has been modified to better clarify the wording and provide correct section reference to 10 CFR 20.1601 (i.e. "c") for regulatory guidance on High Radiation Areas. Since the requirements are not changed. this is an administrative change with no impact on safety. A.3 CTS 6.12.1.c footnote has been modified in a Note to ITS 5.0 which clarifies the wording and intent of this CTS footnote. Since this is a clarification of intent which is consistent with current Technical Specifications. this change is administrative and will not impact safety. ~' ' ~ A.4 Not used. l TECHNICAL CHANGES MORE RESTRICTIVE None FERMI - UNIT 2 1 REVISION 14 08/26/99l

E o e ECCS Instrumentation B 3.3.5.1 BASES APPLIC/6LE SAFEfY ANAL (SES. LCO. 6.d igELipyltu - (antinued) analysis of the recirculation line break (Ref.1). The core cooling function of the ECCS, along with the scram action of the RPS. ensures that the fuel peak cladding temperature remains below the limits of 10 CFR 50.46. The Reactor Steam Dome Pressure-Low signals are initiated from four pressure transmitters that sense the reactor dome pressure. The Allowable Value is low enough to prevent overpressuring the equipment in the low pressure ECCS, but high enough to ensure that the ECCS injection prevents the fuel peak cladding temperature from exceeding the limits of 10 CFR 50.46. Four channels of Reactor Steam Dome Pressure-Low Function are only required to be OPERABLE when the ECCS is required to be OPERABLE to ensure that no single instrument failure can preclude ECCS initiation. Refer to LCO 3.5.1 and LCO 3.5.2 for Applicability Bases for the low pressure ECCS subsystems. 1.d. 2.h. Manual Initiation b 3 The Manual Initiation channel provides manual initiation ~~ E capability by means of individual component controls. There-R is one manual initiation channel for each of the CS and LPCI subsystems (i.e.. two for CS and two for LPCI). The Manual Initiation Function is not assumed in any accident or transient analyses in the UFSAR. However, the Function is retained for overall redundancy and diversity of the low pressure ECCS function as required by the IRC in the plant licensing basis. c4 There is no Allowable Value for this Function since the channels are mechanically actuated based solely on the position of the individual components. Each channel of the Manual Initiation Function is only required to be OPERABLE Y when the associated ECCS is required to be OPERABLE. Refer to LC0 3.5.1 and LCO 3.5.2 for Applicability Bases for the low pressure ECCS subsystems. 1 FERMI UNIT 2 B 3.3.5.1-10 Revision 14 08/26/99 i L

l LLS Instrumentation B 3.3.6.3 j . l} wGch APPLICABILITY 'The LLS instrumentation is recuired to be OPERABLE in MODES 1, 2, and 3 since consicerable energy is in the nuclear system ~and the SRVs may be needed to provide pressure relief. If the SRVs are needed, then the LLS function is required to ensure that the primary containment design basis is maintained. In MODES 4 and 5, the reactor pressure is low enough that the overpressure limit cannot be a>proached by assumed operational transients or accidents. Tius, LLS instrumentation and associated pressure relief is not required. ACTIONS Al The failure of any reactor steam done pressure instrument channel to provide the arming, SRV opening and closing pressure set)oints for an individual LLS valve does not affect the a)111ty of the other LLS SRV to perform its LLS function. A LLS valve is OPERABLE if the associated logic has one Function 1 channel, two Function 2 channels, and at least three Function 3 channels OPERABLE. Therefore,14 '3 days is provided to restore the inoperable channel (s) to ) OPERABLE status (Required Action A.1). If the inoperable channel (s) cannot be restored to OPERABLE status within the allowable out of service time, Condition C must be entered and its Required Action taken. The Required Actions do not allow placing the channel in trip since this action could result in an instrumented LLS valve actuation. The 14 day Completion Time is considered appropriate because of the redundancy in the design (two LLS valves are provided and any one LLS valve can perform the LLS function) and the very low probability of multiple LLS instrumentation channel failures, which renders the remaining LLS SRV inoperable, -g occurring together with an event requiring the LLS function during the 14 day Completion Time. l B.1. B.2. and B.3 Although the LLS circuitry is designed so that operation of a single tailpi)e pressure switch will result in arming both LLS logics: eac1 tailpipe pressure switch provides an input to both LLS logics. Since any overpressure event will normally open at least five SRVs and actuate their associated pressure switch inputs, the LLS logic and instrumentation remains capable of performing its safety function even with several SRV tailpipe pressure switch ) l FERMI UNIT-2 B 3.3.6.3-4 Revision 14, 08/26/99 L A
C i s, LLS Instrumentation B 3.3.6.3 BASES ACTIONS (continued) instrument channels inoperable. Therefore, it is acceptable f{M hours, per Required Action B.1 and B.2. verification and/or for plant operation to continue provided that within 24 I restoration is made to ensure at least: a) one tailpipe g pressure switch in each Division OPERABLE on' one OPERABLE l N SRV in the lowest SRV setpoint group: and b) at least 11 i OPERABLE SRVs have at least one OPERABLE tailpipe pressure lm switch. Therefore, it is acceptable for plant operation to-4 continue even with only one tailpipe pressure switch l 21 OPERABLE on each SRV. However, this is only acceptable lD provided each LLS valve is OPERABLE. (Refer to Required Action A.1 and C.1 Bases). I Required Action B.3 requires restoration of both tailpipe I pressure switches on = 11 OPERABLE SRVs. including 4 SRVs g out of the 5 lowest relief setpoint OPERABLE SRVs. to i s OPERABLE status, prior to entering MODE 2 or 3 from MODE 4. This will ensure that sufficient switches are OPERABLE at the beginning of a reactor startup (this is because the switches are not accessible during plant operation). The p Required Actions do not allow placing the channel in trip since this action could result in an inadvertent LLS valve actuation. As noted. LC0 3.0.4 is not applicable thus l allowing entry into MODE 1 or 2 from MODE 2 or 3 with inoperable channels. This allowance is needed since the channels only have to be repaired prior to entering MODE 2 or MODE 3 from MODE 4. A Note has been provided in the Condition to modify the Required Actions and Completion Times conventions related to e LLS Function 3 channels. Section 1.3. Completion Times. O specifies that once a Condition has been entered. subsequent divisions, subsystems, components, or variables expressed in >g the Condition, discovered to be inoperable or not within limits, will not result in separate entry into the Condition. Section 1.3 also specifies that Recuired Actions g of the Condition continue to apply for each adcitional failure, with Completion Times based on initial entry into the Condition. However, the Required Actions for inoperable LLS Function 3 channels provide appropriate compensatory 4 measures for separate inoperable Condition entry for each SRV with inoperable tailpipe pressure switches.
