JAFNPP 3.0 Bas _es - Continued F. LCO 3.0.F establishes the allowance for restoring equipment to service under administrative controls when it has been removed from service or declared inoperable to comply with required actions. The sole purpose of this Specification is to provide an exception to LCO 3.0.B to allow testing to demonstrate: (a) the operability of the equipment being retumed to service; or (b) the operability of other equipment.
The administrative controls ensure the time the equipment is retumed to service in conflict with the requirements of the required actions is limited to the time absolutely necessary to perform the allowed testing. This Specification does not provide time to perform any other preventive or corrective maintenance.
An example of demonstrating the operability of the equipment being retumed to service is reopening a containment isolation valve that has been closed to comply with the required actions and must be reopened to perfomi the testing.
An example of demonstrating the operability of other equipment is taking an inoperabie channel or trip system out of the tripped condition to prevent the trip function from occurring during the performance of testing on another channel in the other trip system. A similar example of demonstrating the operability of other equipment is taking an inoperable channel or trip system out of the tripped condition to permit the logic to function and indicate tne appropriate response during the performance of testing on another channel in the same trip system.

If any of these three conditions cannot be satisfied, declare the associated ECCS inoperable.
An inoperable instrument channel need not be placed in the tripped condition where this would cause the Trip Function to occur. In these cases, if the inoperable instrument channel is not restored to operable status within the required time, declare the associated ECCS inoperable.
" This action applies to that trip system with the greatest number of inoperable instrument channels. If both systems have the same number of inoperable instrument channels, the ACTION can be applied to either trip system.
- 2. When a channel is placed in an inoperable status solely for performance of required surveillances, entry into associated Umiting Conditions For Operation and required actions may be delayed as follows: (a) for up to 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> for single channel Trip Functions; or (b) for up to 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> for the remaining Trip Functions provided the associated Trip Function maintains ECCS initiation capability.

INSTRUMENTATION SURVEILLANCE TEST INTERVALS, ALLOWABLE l QUT-OF-SERVICEllMESJWD_DIHER.CBARGES (JPTS-20-010) f
- 1. DESCRIPTIOfLAND PURPOSE OF THE PROPOSED CHANGES This application requests the following changes to the James A. FitzPatrick Technical- !
Specifications:
i
- 1. Incorporate the results of the General Electric Licensing Topical Reports, prepared under the direction of the BWR Owners Group, supporting an increase of the ,
sumeillance test intervals (STI), and the repair and testing allowable out-of-service times (AOT), for most of the instrumentation listed in the Technical Specifications. l
- 2. Remove instrument response time limits. ,
- 4. Make additional miscellaneous changes to the instrumentation sections.
I Because of the extensive nature of the changes, the exact wording of the proposed changes to the Technical Specifications (TS) are not provided in the following ;
description. The proposed changes are described in sufficient detail so that, when j
reviewed in conjunction with the revised TS pages in Attachment I and the marked-up TS pages in Attachment lit, a clear understanding of the changes to each specification '
and the referenced tables is provided. i Minor changes in format, such as type font, margins or hyphenation, are not described in j this submittal. These changes are typographicalin nature and do not affect the content !
of the Technical Specifications. ,
The proposed changes to the James A. FitzPatrick Technical Specifications are grouped [
into four categories. These categories and the intended purpose of the changes are as ;
follows
- 1. Incorocrate STI and AOT improvements - Category _1 i This application proposes an extension of the surveillance test intervals (STis) from weekly or monthly to quarterly for the functional tests for most of the instrumentation in the Technical Specifications. Additionally, allowable out-of-service times (AOT) are proposed for the instrumentation. These times, specified separately for both repair and test situations, represent the time that the instrument may be inoperable before entry into its Limiting Condition For Operation action statement. The bases for these changes are presented in seven NRC approved ,
General Electric Licensing Topical Reports (References 1 through 7), prepared l under the direction of the BWR Owners Group.
I I
l
.- l i
. Attachment li to JPN-94-050 SAFETY EVALUATION Page 2 of 39 The STI and AOT revisions will enhance plant safety by reducing the potential for l test related plant scrams, excessive test cycles on equipment, and operator errors. j l
- 2. flelacation ollnstwment Responselirne Limits - CategoIy_2 This application incorporates a line-item TS improvement that implements the guidance of Generic Letter 93-08, " Relocation of Technical Specification Tables of Instrument Response Time Limits" (Reference 24). The NRC guidance permits the relocation of the instrument response times from the TS to the Updated FSAR ,
(UFSAR). Maintaining the response times in the UFSAR permits changes under the regulatory provisions of 10 CFR 50.59 without the need to use the license amendment process. The change does not alter the surveillance requirements for these limits.
The change to the TS involves the deletion of the two TS tables that specify instrument response time limits (Table 3.1-2, " Reactor Protection System Instrumentation Response Times," and Table 3.2-9, " Primary Containment isolation System Actuation Instrumentation Response Times"). The response time limit requirements will be relocated to the UFSAR in the July 1995 annual update.
- 3. Delete APRM Downsca!e Scram - CateQQIy.3 This application proposes a change to delete the APRM downscale scram function i listed in Technical Specification Table 3.1-1, " Reactor Protection System (Scram) ir.strumentation Requirements." This function does not independently initiate a scram. The APRM downscale scram actually serves as an Intermediate Range Monitor (IRM) high flux scram interlock that bypasses the IRM high scram when both of the following conditions exist: (1) Reactor is in the RUN mode, and (2)
APRM power level is above the APRM downscale trip setpoint (above 2.5%). This interlock feature is described in section 7.5.5.4 and Table 7.5-4 of the UFSAR.
The change will permit removal of the APRM downscale scram from the design of
. the RPS system. Removal of this interlock feature will defeat the IRM high scram in the RUN mode irrespective of the APRM power level. The rod block and i' annunciator functions associated with the APRM downscale trip will remain.
The change will permit any one IRM channel per trip system and any one APRM 3 channel per trip system to be simultaneously bypassed, as intended by the plant !
design (UFSAR 7.5.5.3 and 7.5.7.4), avoiding the need to operate the plant in the
" half scram" condition. Due to the different number of APRM and IRM channels (six vs. eight) wme IRM channels share the same APRM channel. Consequently, some combinations of bypassed IRM and APRM channels results in less than the minimum number of required operable APRM downscale scrams. For these combinations, one of the failed channels cannot be bypassed, leaving the plant in a
" half scram" condition. The change will provide the IRM and APRM channel i bypass flexibility intended by the original plant design without the need to operate l the reactor in a " half scram" condition. j i

- 4. MiscellaDegus_ Changes - CategoIy_4 Changes that include editorial revisions, clarification improvements, relocation of material, and revisions to conform the TS to the actual plant design as described in the FSAR. .
The following describes the changes and their purpose. For ease of review, the discussion has been structured to parallel the order of presentation in the Technical Specifications. The page numbers specified in the heading of each change description pertain to the location of the subject material in the current Technical Specifications.
These page numbers are the same for the location of the subject material in the revised Technical Specifications unless otherwise noted in the discussion. The category of each change (CAT 1, 2, 3, or 4) is specified in each change description.

- 2. Page v: Delete Tables 3.1-2 and 3.2-9 from List of Tables. The change reflects the removal of instrument response time limits in accordance with NRC Generic Letter 93-08. Revise the table titles and page numbers to reflect changes described later in this section. (CAT 2 and 4)
- 3. Page vii: Delete Figures 4.1-1 and 4.2-1 from List of Figures. The change reflects the addition of new STI / AGTs based on several GE Licensing Topical Reports as discussed later in the safety evaluation. (CAT 1)
B. Specification 1.0. Definitions. Pagej
- 1. Page 5: Add a new definition: "T. Instrument Surveillance Frequency
, Notations / Intervals," that defines surveillance frequency notations and intervals.
The definition conforms with the definition in the Standard Technical Specifications (Reference 17), Table 1.1, page 1-7. The new definition permits the use of notations for surveillance intervals on the instrumentation tables subject to changes in this amendment application, and relates all surveillance intervals to a consistent and precise time pericd.
Further, the definition clarifies "once each operatic.g cycle", and simllar phrases, by relating the interval to the definition of the frequency notation "R". This will apply the definition of "R" to test frequencies based on operating cycle intervals as used throughout the Technical Specifications, in addition to the "once per operating cycle" requirement used on pages subject to this application. In this manner, a consistent and precise time period will be established for all operating cycle requirements in the TS. (CAT 4) 1

The AOT value conforms to General Electric Licensing Topical Report NEDC-30851P-A (Reference 1), pages 5-33; and NRC Safety Evaluation Report (Reference 8): Enclosure 2, page 1. The Limiting Condition for Operation (LCO) used in note 1 of Table 3.1-1 addresses an NRC concem (Reference 16) that a loss of scram function may occur if two or more channels are inoperable during the 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> AOT. The LCO uses the text, with some minor editorial changes, as that approved in an operating license amendment for the Duane Amold Energy Center (Reference 23). Failure of multiple channels in an RPS trip function may result in a loss of scram function if tripping the channels is delayed by the AOT. Note 1 requires confirmation within one hour of RPS functional capability after two or more channels become inoperable. Further, the LCO limits the inoperable channels in one of the trip systems to a 6 hour6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> AOT. (CAT I)

The turbine first stage pressure permissive listed in Table 4.1-1, page 45, is not listed in the STS used for the markup TS page in LTR NEDC-30851P-A.
However, the oermissive provides an interlock feature that bypasses the turbine control valve fast closure, and turbine stop valve closure, when turbine first stage pressure is below a point corresponding to 30% rated thermal power (FSAR 7.2.3.8), and therefore should be considered an integral part of the scram features subject to the quarteriy functional test interval.

The NRC inspector was concemed that the absence of these instruments from Table 3.2-1 may result in the inoperability of these instruments when primary ;
containment integrity is required by Specification 3.7.A.2. The relocation subjects i these instruments to the operability requirements of Specification 3.7.A.2. These ;

- RCIC turbine steam line high flow ,
- RCIC steam line low pressure l
- RCIC steam line/ area temperature, l
Add action statement F to the table for these valve isolation functions. Action 1 statement F is described in renumbered note 3. With less than the minimum !
number of instrument channels operable, action statement F requires that the. l affected penetration flowpath be isolated within one hour, and the affected system i declared inoperable. Closing an isolation valve on the penetration assures that the -l associated system (HPCI or RCIC) is isolated when a portion of the pipe break l protection is in a degraded condition.- Declaring the HPCI or RCIC system j inoperable, limits continued plant operation to the seven day AOT specified for an ;

Accordingly, the new note 1 to Table 3.2-2 is revised to conform with the following features of the action statement in Table 3.3.3-1 of the STS (Reference 17):
- a. The current action statement (note 1) requires that the trip system be placed in the tripped condition if at least one of the channels is inoperable. This is not the intent of the action statement, since placing a trip system in the tripped condition would initiate ECCS. The revised action statement (note ia) specifies a trip of the inoperable channel as the appropriate response to an inoperable condition. Tripping the inoperable channel will complete the safety function of the channel and permits the operable portion of the logic to function as designed (initiate ECCS in response to an actuation signal). (CAT 4)
- b. The current action statement requires the reactor to be placed in the cold condition within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> if the LCO is not satisfied. The current requirement can be interpreted in a manner that is inconsistent with the requirements of Technical Specification 3.5.F which identifies ECCS subsystem operability requirements when in cold shutdown. The revised action statement removes this inconsistent action requirement by declaring the " associated ECCS inoperable" when an inoperable instrument channel is not placed in the tripped condition within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

The change reflects the as-built configuration of the control rod block initiation logic (UFSAR 7.7.4.3). The control rod block (CRB) logic is designed as a "1 out of n" logic, where n is the total number of CRB channels. Only one input need be in the trip condition on either logic to effect a rod block signal. For example, the APRM rod block trip logic is based on one out of six, not one out of three taken twice logic. The change conforms to STS (Reference 17), Table 3.3.6-1, page 3-51 and 3-52. (CAT 4)

Attachment il to J' PN-94-050 SAFETY EVALUATION Page 18 of 39 Split the current note 1 into two notes (notes 1 and 2). Note 1 presents the operating mode requirements for the CRBs. This change does not change the operability requirement of the current specification. Note 2 presents the AOTs and action statements for the CRBs in a manner that conforms to the STS (Reference 17): pages 3/41-18, 3/4 3-51, and 3/4 3-52, except that the 7 day AOT for the Action B instruments (RBM) is retained since this is a plant specific value. Some minor editorial. changes have been incorporated into the action statements in note 2 to establish consistency with the required action language used for the other tables in TS 3.2. New note 2 replaces the AOTs in existing notes 1 and 10 (note 10 is therefore deleted). The change is also consistent with the NRC Safety Evaluation Report (Reference 14). The new AOTs / A,ction Statements differ in substance from the current TS as follows:
a) The required action for Action A instruments is the same as the current TS except for (1) the deletion of accelerated testing requirements for the operable system when less than the minimum nunsber of operable channel are operable, and (2) adds a one hour time period to implement a required trip. The changes conform to the STS (Reference 17).
The accelerated testing requirement is unnecessary based on the absence of a similar provision in the General Electric Licensing Topical Report GENE-770 1-A, and STl/AOT amendments approved for other plants (Reference 23).
Frequent testing will reduce instrument reliability due to increased out-of-service time to perform the testing, and increases the risk of test-induced trips. (CAT 1) b) The required action for Action B instruments (RBM) requires that the reactor not be operating in the Umiting Control Rod Pattern, which is consistent with TS 3.3.B.5 on page 94.'

- 11. SAEEIUMP11CAllDNS_0E.IHE PROPOSED _CBANGES The proposed changes to the James A. FitzPatrick Technical Specifications are grouped into four categories. The safety implications associated with each of these change categories are as follows:
- 1. Incorporate STI aud.AOT Improvatnents_ .CategoIy 1 The amendment will extend the Reactor Protection System (RPS), Primary Containment isolation System (PCIS), Emergency Core Cooling System (ECCS),
Control Rod Block (CRB), and Recirculation Pump Trip (RPT) instrumentation functional test intervals from weekly or monthly to quarterly as described in the previous section. The interval for the functional test of the automatic scram contactors will change from "every refueling outage" to " weekly" using either the channel functional test or the RPS Channel Test Switches. The bases for this change is documented in General Electric Licensing Topical Report NEDC-30851P-A (Reference 1) which concludes that a common cause failure of the scram contactors is a major contributor to RPS unavailability.
Additionally, allowable out-of-service times, as described in the previous section, are specified for the instrumentation These times, specified separately for both repair and test situations, represent the time that the instrument may be rendered inoperable before entry into its associate Limiting Condition For Operation action statements.
The bases for these changes are presented in generic evaluations developed by the BWR Owners Group, submitted to the NRC in seven GE Licensing Topical Reports (References 1 through 7), and approved by NRC Safety Evaluation Reports (References 8 through 15). These generic evaluations are applicable to the FitzPatrick design as documented in References 26 through 31.
The generic evaluations utilize fault tree modeling to estimate the impact of the proposed STI and AOT changes on the instrument system failure frequency. The acceptance criteria used in the analyses for the proposed changes is based on a net change in risk. The net change in risk is the difference between the increase in risk that results from the longer STI / AOT, and the decrease in risk that results from the reduced likelihood of inadvertent scrams due to a reduction in testing. The generic evaluations concluded that the net change in risk is negligible. Further, the evaluations concluded that the overall effect of the proposed changes provides a net increase in plant safety when all factors are considered. This increase in plant safety is achieved by reducing the potential for: (a) unnecessary plant scrams (reduced challenges to plant shutdown systems and improved plant availability); (b) excessive test cycles on equipment (reduced wear-out potential); and (c) diversion of plant personnel and resources on unnecessary testing (potential safety and operational improvement).
The NRC Safety F. valuations Reports (References 8 through 15) concluded that the GE Licensing Topical Reports provide an acceptable generic basis for supporting plant-specific Technical Specification changes. The SER further states that each applicant for a license amendment must confirm the plant-specific applicability of the
I Attachment 11 to JPN-94-050 SAFETY EVALUATION Page 25 of 39 generic evaluations. A plant specific evaluation was performed for each instrumentation category. The evaluations compared the instrumentation design configurations and surveillance requirements to the generic model used in the GE Ucensing Topical Reports. Differences were identified and assessed as to their impact on instrumentation reliability calculated for the generic models. Additionally, the setpoint drift expected under the extended STis was evaluated to determine the acceptability of current setpoint calculations. Provided below is a summary of the plani specific evaluations performed by the Authority (References 26 through 31) that address the proposed changes.

S.ER Requiremeal Demonstrate by use of current drift information provided by the equipment vendor or plant-specific data, that the drift characteristics for instrumentation used in the RPS channels in the plant are bounded by the assumptions used in l NEDC-30851-P-A when the functional test interval is extended from monthly to quarterly.
The NRC staff provided additional guidance in a letter from C. E. Rossi (NRC) to R. F. Janecek (BWR Owners Group), dated April 27,1988, which states that:
"... licensees need only confirm that the setpoint drift which could be expected under the extended STls has been studied and either (1) has been shown to remain within the existing allowance in the RPS and ESFAS instrument setpoint calculation of (2) that the allowance and setpoint have been adjusted to account for the additional expected drift."
Baat-Specific Response ,
Actual plant setpoints are set conservatively with respect to the Technical Specification limits to accommodate for the uncertainty associated with each particular instrument channel and associated test interval. Trip settings are adjusted, as necessary, when the instrument channel is calibrated and/or functionally tested. At the FitzPatrick plant, RPS calibrations, except for the LPRMs, occur at three months or longer intervals. Since the setpoints are set to accommodate the longer calibration intervals, the setpoint drift will be
l Attachment il to JPN-94-050 SAFETY EVALUATION Page 26 of 39 acceptable between the quarterly functional test. The LPRM output is checked daily using a heat balance and adjusted as necessary to maintain an acceptable level of setpoint drift.
Confirmation that postulated setpoint drift associated with the longer functional test interval is within existing safety margins was established by reviewing the instrument calibration and functional test results (Reference 26).
- c. SER Requitement Confirm that the differences between the parts of the RPS that perform the trip functions in the plant and those of the base case plant were included in the analysis for the plant using the procedures of Appendix K of NEDC-30851-P-A, or provide plant-specific analyses to demonstrate that there is no appreciable change in RPS availability or public risk.
Plant -Specdic_ Evaluation NEDC-30851P-A concludes that RPS failure frequency is predominately a function of common cause failures of the scram contractors. There are no significant variations between the FitzPatrick RPS scram contractor configuration and the generic model. The FitzPatrick RPS differs from the generic model in sensor logic, sensor relays, scram valve design, backup and manual scram actuation, and technical specification requirements. These differences were identified, and evaluated in accordance with NEDC-30851P-A, Appendix K, procedures (Reference 26). This evaluation found the design l differences to have a negligible effect on RPS failure frequency, based on the case studies presented in NEDC-30851P-A, Appendix K.

The FitzPatrick plant is a BWR/4 NSSS with an ECCS, PCIS, CRB, and RPT l relay instrumentation design which is very similar to the BWR 3/4 base case I model used in the generic instrumentation reliability analyses (NEDC-30851P-A, l Supplements 1 and 2, NEDC-30936P-A, NEDC-31677P-A, GENE-770-06-1, and GENE-770-06-2-A).

l i
Attachment 11 to JPN-94-050 SAFETY F. VALUATION Page 27 of 39 There are no significant differences between the generic model (NEDC-31677P-A) and the FitzPatrick design for PCIS instrumentation common to the RPS.
The only significant differences between the generic model and the FitzPatrick design for non-common PCIS instrumentation are the number of sensor variables that isolate RWCU, and the logic for actuating Secondary Containment isolation. These differences were evaluated using the case studies contained in NEDC-31677P-A and were found to have an insignificant effect on isolation functiori failure frequency (Reference 29).
Their are no significant differences between the generic model and the FitzPatrick design for CRB instrumentation. The generic evaluations (References 1 and 7) for the CRB function are applicable to plants with either Rod Block Monitors (RBM) or Rod Withdrawal Limiters (RWL) since they provide equivalent protection. The Fitzpatrick plant uses the Rod Block Monitor (RBM) for the CRB function (Reference 30).
The BWR/4 RPT system design considered in the generic evaluated (GENE-770-06-1), is a two-out-oi-two taken once logic per trip system for either reactor low water level or reactor high pressure. The Fitzpatrick RPT system is initiated by a one-out-of-two logic taken twice, from the same signals. The Fitzpatrick logic design is bounded by the generic evaluation since it is inherently more reliable (Reference 31).

Since the setpoints are set to accommodate the longer calibration intervals, the setpoint drift will be acceptable between the quarterly functional tests. Therefore, changing the functional test interval from weekly or monthly to quarterly does not impact the :

Confinnation that postulated setpoint drift associated with the longer functional test interval is within existing safety margins was established by reviewing the instrument calibration and functional test results (References 27, 29, 30, and 31).

SAFETY EVALUATION ,
Page 28 of 39 Mowable Out-of-Service Time Bases The test allowable out-of-service times (AOT) provide a reasonable period of time to perform testing on an instrument channel made inoperable to perform required surveillance. An instrument channel removed from service (made inoperable) to ,
perform required surveillance must be restored to service (made operable) in less than or equal to the six hour AOT, unless the instrument channel is found to be in need of repair At that time, the instrument channel is declared inoperable and the repair AOT is entered.
When the repair AOT is entered for an inoperable instrument channel, a verification that sufficient instrument channels remain operable or tripped to maintain trip capability for that trip function is performed (if one or more additional instrument channels for the same trip function are also inoperable) and, within the time period specified in the repair AOT, the instrument channel: a) must be restored to service in an operable status or, b) must be placed in a tripped status or, c) the associated trip system must be tripped. If the required actions are not completed within the time-period specified by the repair AOT, then the specified action for that trip function must be taken within the time period stated in the ACTION (e.g., insert all operable control rods within four hours; isolate the main steam lines within eight hours; declare the associated ECCS inoperable; place the reactor in the startup/ hot standby mode within the next six hours).
When the repair AOT is entered, the entire time period specified by the AOT is available, even though it might become apparent that the repair cannot be completed within the allowed time, because analysis performed in support of the Licensing Topical Reports assumed that the entire time period specified in the AOT was used in each case. While it is expected that the entire time period specified by the AOT will seldom be needed, allowing the entire time period specified to be used in determining when required actions must be completed avoids situations where interpretation is necessary, and simplifies training in the use of the new AOTs.
The values for the proposed test ano repair AOTs are based on the Ucensing Topical Reports previously referenced. The AOT text proposed for the five instrument groups (RPS, PCIS, ECCS, CRB, and ATWS RPT) differ to reflect: (1) each instrument group's unique AOT value as presented in the Topical Reports , (2) the action statements associated with the function of the instrument group, and (3) distinctions in the trip logic of each instrument group. The objective of the proposed Technical Specifications is to optimize consistency in the AOT text for the different instrument groups to the extent possible. Compliance with this objective minimizes the complexity of the TS which will improve operator understanding of the AOTs, reduce the potential for a TS violation resulting from a misinterpretation, and simplify operator training in the use of the TS.
Accordingly, a similar repair AOT text was applied to four of the instrument groups (all except the CRB). The text conforms to the AOT approved for the RPS AOT for Duane Amold (Reference 23), and Nine Mile Point 1 and 2 (References 33 and 34),
except for some minor editorial changes. The AOT recognizes the impact of multiple channel failures on trip function operability. The LCO for the AOT precludes the use '
of an AOT in excess of one hour for those situations where the multiple channel
Attachmsnt 11 to JPN-94-050 SAFETY EVALUATION Page 29 of 39 failures reder the trip function inoperable. Only when the failure does not prevent trip function capebility will the full AOT recommended by the Topical Reports be permitted. In this nonner, the application of the AOT is maximized without jeopardizing the operat>My of the trip function. Additionally, this approach minimizes the potential for operation with an instrument channel or trip system in the tripped condition which increases the potential for a plant transient. The LCO for the AOT meets these objectives by requiring, within one hour of a multiple instrument channel failure, confirmation of trip function capability. If confirmation cannot be satisfied within the one hour period, the action statement is entered. This AOT concept is not applicable to the CRB instrument group due to its unique design; i.e., only one trip system and no action required beyond placing the channel in the tripped condition.
The restrictions on the use of the repair AOT for multiple channel failures conforms to the STS in NUREG-1433 (Reference 18). The STS limits the AOT to one hour if multiple channel failures results in loss of trip capability. Refer to the following sections of NUREG-1433.
RPS LCO 3.3.1.1.C PCIS LCO 3.3.6.1.B ATWS-RPT LCO 3.3.4.2.B ECCS LCO 3.3.5.1.B, C, D, E, F, and G All of the instrument groups use the 6 hour6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> test AOT based on the Topical Reports previously referenced. The text of the test AOT conforms to the text used in NUREG-1433 (Reference 18), and approved for Duane Amold (Reference 23) and NMP-2, except as noted below. For multiple channel trip systems, the AOT is permitted only when the removal of the channel from service to test does not prevent trip function capability. Only single channel trip systems, and trip systems based on a two-out-of-two-taken-once logic, as specified in the AOT statement, are excluded from this restriction. Several deviations from the AOT text used in NUREG-1433 are proposed for the PCIS trip functions. These deviations are described, along with their bases, in change description O.7.
- 2. Belocation of Instrument Response Time Limits - CategoIy_2 The change deletes the RPS and MSIV isolation instrumentation response time limits from the Technical Specifications. The July 1995 UFSAR update will incorporate the response time limit requirements. These changes conform with the NRC guidance presented in Generic Letter 93-08 (Reference 24). The surveillance requirement in ,
TS 4.1.A and TS 4.2.A that confirms the response time limits every eighteen months remains unchanged. The plant surveillance procedures for response time testing (ISP-102 through ISP-111) include acceptance criteria that reflects the response time limits in Tables 3.1-2 and 3.2-9.
Incorporation of these requirements into the UFSAR will assure that the NRC is maintained informed of this design feature. Any changes to the response time limits contained in the UFSAR will be evaluated under 10 CFR 50.59.

There are no safety considerations associated with this change since it does not involve any changes to the response time limits, surveillance requirements, or procedural changes that impact plant operations.
Although the APRM downscale trip is listed as an RPS scram (Tables 3.1-1 and 4.1- l 1), it does not directly initiate a reactor trip. The trip performs an interlock function associated with the IRM high flux scrarn. The interlock prevents the IRM high flux scram function from being defeated in the Run operating mode until the APRM downscale setpoint has cleared (power above 2.5%).
The bases for deleting the APRM downscale scram function is presented in a :
General Electric evaluation performed for the Dresden and Quad Cities plants ,
(Reference 22) and is repeated in the following paragraphs. This evaluation is applicable to the FitzPatrick plant based on similarity to the Dresden design. This function existed on several early plants but has been deleted from later plant designs. It is no longer required by the STS and has been deleted from the Technical Specifications of several plants that originally included it in their design. '
References 20 and 21 identify two license amendments that removed this scram feature from other BWR plants.
Deletion of the APRM downscale scram function will permit all available combinations of inoperable IRM and APRM channels to be simultaneously bypassed, as intended by the plant design (UFSAR 7.5.5.3 and 7.5.7.4). Due to the different number of APRM and IRM channels (six vs. eight), some IRM channels share the same APRM channel in the APRM downscale scram logic. Consequently, some bypass combinations of inoperable IRM and APRM channels would result in less than the minimum number of required operable APRM downscale scram trips, precluding bypass capability for one of the inoperable channels. Under these circumstances, the plant must remain in a " half scram" condition. Removal of this 1 trip function will avoid the need to operate the plant in the " half scram" condition, with l the associated risk of a plant transient, for certain inoperable IRM/APRM i combinations. l l
Removal of the APRM downscale scram function from the Technical Specifications is not a safety concem for the following reasons-
- a. The design basis accident in this region of operation is the control rod drop accident (CRDA). The only scram function that the FSAR takes credit for in the mitigation of the CRDA is the APRM 15% power fixed high neutron flux scram (startup mode) which is assumed to occur at 120% power (UFSAR 14.6.1.2).
- b. If the mode switch is changed to the Run mode prematurely during startup, or if the reactor power is reduced too far before changing the rnode switch to the !
Startup mode, the control rod block associated with the APRM downscale trip l will activate, precluding further control rod withdrawal. This control rod block feature is required by the Technical Specifications (Table 3.2-3), and is not ,
altered by the requested change. I 1

- c. During cold plant startups, prematurely changing to the Run mode will likely result in MSIV closure and consequent scram due to insufficient steam pressure.
Currently, the plans are to implement a modification to remove the APRM downscale scram function, contingent on NRC approval of this amendment request, during refueling outage Reload 12/ Cycle 13 (scheduled to start in early 1997). The surveillance requirements currently specified for the APRM downscale scram function will continue during the period between the issuance of the amendment and the completion of the modification removing this function.
- 4. Miscellaneous Changes - CategofyJ The miscellaneous changes are grouped into four subcategories and evaluated as follows:
- a. Editorial Changes Editorial changes include the relocation of text, renumbering of table notes, and corrections in nomenclature. These changes are necessitated by other text changes in this application, and do not change any Technical Specification requirement. Changes: A.1, A.2, B.2 D.2, D.5, F.9, F.10, F.11, F.12, F.13, F.14, G.2, G.4, G.10,1.3, 0.1, 0.10, P.1, Q.3, O.8, R.4, T.4, U.4, V.3, W.2 and X.2.
- b. Clarifications The clarification changes either (1) establish consistency with the actual design of the plant instrumentation as described in the UFSAR, (2) establish consistency between different TS requirements, or (3) define TS requirements more explicitly. By enhancing the accuracy and clarity of the text, the changes will assure a correct interpretation of the TS instrumentation requirements, essential to the safe operation of the plant. The changes in this group are as follows:
(1) Use of notations for the surveillance frequencies assures a precise and cleariy defined time interval. The change conforms to the STS (Reference 17). Change: B.I.
(2) Establish consistency among the Limiting Conditions For Operation (LCO) for related systems by conforming to the more conservative LCO.
Changes: P.S.b, and P.7.
(3) Changes to reflect the actual design of instrumentation described in the UFSAR.
This includes the change that relates the requirement for the minimum number of operable control rod block channels to " trip function" rather
Attachment il to JPN-94-050 SAFETY EVALUATION Page 32 of 39 than " trip system." While the rod block logic circuitry is arranged as two similar logic circuits, (i.e., one-half of the sensors provide inputs to one logic circuit, that other half to the other logic circuit), either logic circuit independently provides a rod block signal to inhibit rod withdrawal. The current Technical Specifications splits the channels into two groups for each CRB function for the purpose of establishing the minimum number of operable instrument channels per trip system. This prohibits the bypass of more than one channel per group. Under the proposed change, the total number of channels within a CRB function that may be bypassed will remain at two. However, any two of the channels could be bypassed without consideration of its grouping. Therefore, the reliability of the CRB function will not be compromised by the change.
The change will permit the bypass of all available combinations of two IRM channels or two APRM channels using their associated bypass switches, as intended by the plant design (UFSAR 7.5.5.3 and 7.5.7.4).
As wired, certain combinations of bypassed IRM or APRM channels are not permitted by the current CRB Table 3.2-3. For these combinations, inoperable channels resulting in a " half-scram" condition cannot be bypassed. This constraint on the ability to bypass all available combinations of two IRM channels, or two APRM channels, increases the potential for an unnecessary plant transient. The change is consistent with the design of the control rod block system (UFSAR 7.7.4.3), and with the STS (Reference 17), Table 3.3.6-1, page 3-51.
Changes: F.4, G.3, M.1, M.2, M.3, 0.3, 0.4, 0.5, 0.6, P.3, P.4, P.5.a, 0.1, 0.4, U.3, V.2 and W.3.'
(4) Limiting Condition for Operation 3.0.F is added to clearly define the conditions under which inoperable equipment, or equipment removed from service, may be returned to service for the sole purpose to perform testing to demonstrate its operability or operability of other equipment. The LCO requires the application of administrative controls to limit the time to that necessary to perform the testing. Use of this provision permits the repair ,
and retum of equipment to service following the appropriate testing, and i reduces the potential of plant transients that result from operation with instrument channels in the tripped condition. Changes: C, D.4.
5 (5) A note is added to the quarterly calibration requirement for the RWCU Area High Temperature instrument channel in Table 4.2-1 to describe the i
~ '
calibration method for the temperature sensors. The method consists of comparing the active temperature signal with a redundant temperature signal.
Injection of a known temperature signal into RTD's and thermocouples to perform a calibration cannot be performed from a remote location due to I the nature of these devices. The temperature sensors for most instrument and controls systems are calibrated by removing the sensor and placing it into a known temperature bath. However, this method of calibration for the eight RWCU Area High Temperature sensors conflicts with ALARA 1

practices since entry into high radiation areas (ranges from 100.t0 500 E mr/hr in the general area of the temperature sensor) would be required to remove, test, and replace the sensors. For this reason, a comparison method of calibration is used. This involves a comparison of the output of the temperature sensors used for the trip function with another temperature sensor that monitors the same parameter. The acceptance p criteria currently used is s 10 F differential. Change: T.3 and W.1
This change relocates the operability and surveillance requirements for the HPCI and RCIC isolation actuation instrumentation from the ECCS tables (Tables 3.2-2 and 4.2-2) to the Primary Containment Isolation tables (Tables 3.2-1 and 4.2-1). The proposed location is the appropriate location for these -
instruments, and conforms to the STS (Reference 17). The change resolves an NRC concem expressed in Reference 19 that the current location does not assure that the instruments are operable when primary containment integrity is _
required. While the Authority interprets the current TS as requiring the operability of the HPC! / RCIC isolation instruments when containment integrity-is required, the change will enhance the clarity of this requirement. Changes:
0.2, P.8, T.1, and U.1.
Ill. EVALUATION OF SIGNIELCANT HAZARQS_C_QNSIDERATION Operation of the FitzPatrick plant in accordance with the proposed Amendment would not involve a significant hazards consideration as defined in 10 CFR 50.92, since it would not:
- 1. involve a significant increase in the probability or consequences of an accident previously evaluated because:
- a. Incoroorate STI and AOT Improvement - Categorv 1 The proposed changes are limited to an extension of the surveillance testing intervals and allowable out-of-service times of plant instrumentation. The changes do not introduce any new modes of plant operation, make any physical changes, or alter any operational setpoints. Therefore, the changes do not degrade the performance of any safety system assumed to function in the accident analysis. Consequently, there is no effect on the probability of occurrence of an accident.
Regarding the consequences of an accident, the GE Ucensing Topical Reports (References 1 through 7) concluded that the proposed extensions in the STI and AOT for the safety system instrumentation results in an insignificant change in the core damage frequency. The extension of the STI / AOTs results in a slight increase in the unavailability of the safety functions. However, this effect is offset by a reduction in the probability of inadvertent plant trips due to
- Attachment il to JPN-94-050 SAFETY EVALUATION Page 34 of 39 reduced testing. The overall effect on the probability of an accident is negligible. While the effects of reducing unnecessary cycles on safety system instrumentation is not quantifiable, the effect will be to further reduce the core damage frequency. The NRC concurred in their SERs (References 8 through
- 15) with these conclusions. Consequently, there is not a significant increase in the consequences of an accident.
- b. Helocation of the InstrumeD1_BBSp0Dse_ lima. Limits _ Cittegorv 2 The change involves the use of an attemate regulatory process for controlling the instrument response time limits. The change does not introduce any new modes of plant operation, make any physical changes, alter any operational setpoints, or change the surveillance requirements.
- c. Delete APRM Downscale_StrlLm - CategoIyj The design basis accident applicable to the startup power region is the Control Rod Drop Accident (CRDA). The FSAR does not credit the APRM downscale scram in the termination of this accident. Accident mitigation is provided by the APRM fixed high neutron flux scram. Therefore, elimination of this scram function has no adverse affect on previously evaluated accidents.
- d. MiscellaneousStianges - CategoryJ The changes do not introduce any new modes of plant operation, make any physical changes, or alter any operational setpoints. The changes involve enhancements that clarify the Technical Specification requirements. ,
- 2. create the possibility of a new or different kind of accident from those previously evaluated because:
- a. Incorocrate STI and AOT improvements - Categorv_1 The proposed changes do not introduce any new accident initiators or failure mechanisms since the changes do not introduce any new modes of plant operation, make any physical changes, or alter any operational setpoints. The changes reduce the probability of accidents initiated by test-induced plant trips.
- b. Belocation_of the Response Time Limits - Categoty_2 - j J
The change involves the use of an attemate process for controlling the )
instrument response time limits. The change does not introduce any accident initiators since it does not involve any new modes of plant operation, make any physical changes, alter any operational setpoints, or change the surveillance requirements.

1
Attachment il to JPN-94-050 SAFETY EVAL.UATION Page 35 of 39 accidents and their removal does not introduce an accident initiator. The limiting accident evaluated in the FSAR for the startup power region is the control rod drop accident. This accident is assumed to occur irrespective of the scram functions provided to terminate this accident.
- d. Miscellaneous _ Changes - Category _4 The changes do not introduce any new accident initiators or failure mechanisms since the changes do not alter the physical characteristics of any plant system or component. The changes involve enhancements that clarify the Technical Specification requirements.
- 3. involve a significant reduction in the margin of safety because:
- a. IDcD_rporate STI and AOT improvements _CategoIy_1 The proposed changes do not alter the manner in which safety limits, limiting safety system settings, or limiting conditions for operation are determined. The affected instrumentation setpoints already account for the effects of drift and include sufficient allowance for an extension in the STis. The evaluations presented in the referenced Licensing Topical Reports concluded that the overall effect of the proposed changes provides a net increase in plant safety.
The improvement is achieved by reducing the potential for: (a) test related plant scrams (reduced challenges to plant shutdown systems and improved plant availability); (b) excessive test cycles on equipment (reduced wear-out potential); (c) operator errors (AOT provides reasonaole time for making repairs and tests); (d) scrams that occur when inoperable channels are tripped because insufficient repair time exists; and (e) diversion of plant personnel and resources on unnecessary testing (potential safety and operational improvement).
- b. Belocation of the Response Time Limits - Category 2 _
The change involves the use of an attemate regulatory process for controlling the instrument response time limits. The change does not introduce any new
, modes of plant operation, make any physical changes, alter any operational setpoints, or change the surveillance requirements.
- c. Relete APRM Downscale Scram - Categoly_3 The only scram function that the UFSAR takes credit for in the mitigation of the limiting accident (control rod drop accident) is the APRM 15% power fixed high neutron flux scram. This scram function, as well as the IRM high flux scram function in the startup mode which could also terminate this accident, are not affected by this change. Only the APRM downscale scram, for which the UFSAR takes no credit in the termination of any analyzed event, is eliminated by this change. The APRM downscale control rod block is not affected by this change. Elimination of the APRM downscale scram will avoid the need to operate the plant in a " half scram" condition for certain IRM/APRM channel bypass combinations, therefore eliminating the potential for an inadvertent plant

transient. For these reasons, the change does not involve a significant reduction in the safety margin.
- d. Miscellan'eous Changes CateQQIyl The changes assure compliance with the Technical Specifications by improving its clarity and accuracy. For these reasons the changes will improve the plant's .
margin of safety.
IV. IMPLEMENTATION OF THE PROPO_ SED _CtLANGES Implementation of the proposed changes will not adversely affect the ALARA or Fire Protection Program at the FitzPatrick plant, nor will the changes impact the environment.
V. COECLQSlQN
' The changes, as proposed, do not constitute an unreviewed safety question as defined in 10 CFR 50.59. That is, they:
1.- will not increase the probability nor the consequences of an accident or malfunction of equipment important to safety as previously evaluated in the Safety Analysis Report;
- 2. will not increase the possibility of an accident or malfunction of a type different from any previously evaluated in the Safety Analysis Report; and
- 3. will not reduce the margin of safety as defined in the basis for any technical specification.
The changes involve no significant hazards consideration, as defined in 10 CFR 50,92.

The primary containment hydrogen and oxygen concentration sample supply and '
' return lines, as well as the gaseous and particulate sample supply and return lines, utilize inboard and outboard isolation valves that are both closed by a single trip system. Hydrogen and oxygen concentration sample supply and return isolation valve control circuits are :'
provided with the capability to override automatic isolation to allow sampling during and following an accident. Penetrations which are isolated by a single automath icolation valve (and a remote manual or check valve) utilize a single trip system to effect dosure of the automatic isolation valve.
10se1EE The main steam line high temperature isolation function utilizes 16 sensors (instrument channels), with 4 sensors located at each of 4 different areas in the vicinity of the rnain steam lines. The 4 instrument channels associated with each of the 4 areas are arranged in a 1-out-of-2-taken-twice logic. Thus a main steam line break in any of the 4 areas will effect closure of all 8 main steam line isolation valves.

i The HPCI high temperature isolation function utilizes 16 sensors (instrument channels) located in the vicinity of the HPCI equipment and piping. The 16 instrument channels provide inputs into two trip systems, eight instrument channels per trip systemc One trip system is 1 associated with the inboard isolation valve and the other trip system is associated with the outboard isolation valves. Trip logic for each trip system is one-out-of-eight-taken-once logic for the high temperature isolation function. The logic for the RCIC high temperature isolation ,
