PACKAGE NUMBER 2 Description and Justification of Proposed Change Illinois Power is requesting a change to Technical Specification 3.3.7.5. The proposed change would add a note to item 14 on Table 3.3.7.5-1 to allow inoperability of primary containment isolation valve position indication when the valve / valve operator is electrically deactivated in the isolated position, such as when a containment isolarAon valve is deactivated and secured in the isolated position (for maintaining containment integrity) according to the provisions of ACTION "a" under Specification 3.6.4.
When any motor-operated cantainment isolation valve is electrically deactivated, its breaker is usually switched to the "0FF" position.
Power is consequently lost to the position indication circuit and all position indication in the main control room is lost. ACTION 82 associated with iten 14 of Table 3.3.7.5-1 will require a plant shutdown after 7 days if all position indication to a primary containment isolation valve is lost. ,
The intent of Technical Specification 3.3.7.5 (Table 3.3.7.5-1 item 14) is to ensure that indication is available in the main control room to enable the control room operators to assess containment integrity. The intent of this specification can be satisfied if the affected valve (s) are placed in the isolated position prior to being deactivated, and if appropriate administrative controls are in place to ensure that the control room operators can determine the valve's position if needed.
Intermittent reopening of these valves under administrative controls should be allowed since the control room operators will be directly '
involved in the valve manipulation and since such a provision is currently specified in Technical Specification 3.6.4.
Basis For No Significant Haznrds Consideration According to 10CTR50.92, a proposed change to the license (Technical Specifications) involves no significant hazards consideration if operation of the facility it. accordance with the proposed change would ,
not (1) involve a significant increase in the probability or consequences of an accident previously evaluated, or (2) create the l possibility of a new or different kind of accident from any accident l previously evaluated, or (3) involve a significant reduction in the !
margin of safety.
(1) The proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated because, under the provisions of the proposed change, the affected valve (s) will be in the isolated / conservative position (except as limitedly provided) . With the proposed change a means still exists that allows plant operators to know the position of an affected containment isolation valve (s). The proposed change is consistent ;
with the provisions of Technical Specification 3.6.4. "Containment l Isolation Valves."
I
- e Attech::nt 3 5 to U-601118 Page 6 of 87 (2) The proposed change does not create the possihA11ty of a new or different kind of accident from any accident previously evaluated because the proposed change introduces no new modes of operation with respect to existing requirements and provisions contained in the Technical Specifications. The proposed change does not involve any changes to the plant's as-built design.
(3) The proposed change does not involve a significa.qt rgduction in a ,
margin of safety because this change does not reduce the , capability of assessing containment isolation during accident conditions or i when otherwise required.

Basis for No Significant Hazards Consideration According to 10CTR50.92, a proposed change to the license involves no significant hazards consideratien if operation of the facility in ,
~
accordance with the proposed change would not (1) involve a significant '
increase in the probability or consequences of an accidant previously evaluated, or (2) create the possibility of a new or different kind of ,
accident from any accident previously evaluated, or (3) involve a significant' reduction in a margin of safety.
(1) The proposed changes do not involve a significant increase in the possibility or consequences of an accident previously evaluated :
because these changes are either (a) administrative (deleting extraneous or outdated information of ,
an administrative nature), or l r
i
Attacheont 3 i 1
to U-601118 Page 14 of 87 (b) are required to provide the correct setpoints and limits ,
determined to be appropriate for the as-built plant design and are consistent with the applicable safety analyses. They are based on the reviewed and approved test results from the Startup Test Program and have been incorporated into the appropriate plant design documents.
(2) The proposed changes do not create the possibility of a new or different kind of accident from any accident previously evaluated because the proposed values are consistent with plant design and/or are based on the operational performance of the as-built plant :
during the Startup Test Program. The values support a plant-specific design basis for Clinton, so their incorporation into the plant design documents and the CPS Technical Specifications doas mot create the possibility of a new or different kind cf accident from ecy previously evaluated.
(3) The proposed changes do not involve a slynificant reduction in a margin of safety because the values proposed have been determined to be consistent with plant design and the corresponding accident analyses. In some cases, the proposed values are values established to support a margin of safety since such values had not been previously established. The proposed changes do not therefore constitute a reduction in a margin of safety.

3/4.4.1 RECIRCULATION SYSTEM The impact of single recirculation loop operation upon plant safety is assessed and shows that single-loop operation is permitted if the MCPR fuel cladding safety limit is increased as noted by Specification 2.1.2, APRM scram and control rod block setpoints are adjusted as noted in Tables 2.2.1-1 and 3.3.6-2, respectively, MAPLHGR limits are decreased by the factor given in Specifica-tion 3.2.1, and MCPR operating limits are adjusted per Section 3/4.2.3.
l Additionally, surveillance on the volumetric flow rate of the operating recir- ;
culation loop is imposed to exclude the possibility of excessive o nternals !
vibration. surveillance on differential temperatures below ( 0 THERMAL 1 POWER or_ 0% rated recirculation loop flow is to sitigate the un thermal l 3og" stress on vessel nozzles, recirculation pump, and vessel bottom head during the :
extended operation of the single recirculation loop mode. l An inoperable jet pump is not, in itself, a sufficient reason to declare a re- l circulation loop inoperable, but it does, in case of a design-basis-accident, increase the blowdown area and reduce the capability of reflooding the core; thus, the requirement for shutdown of the facility with a jet pump inoperable.
Jet pump failure can be detected by monitoring jet pump performance on a pre-scribed schedule for significant degradation. Recirculation loop flow mismatch limits are in compliance with ECCS LOCA analysis design criteria for two recir-culation loop operation. The limits will ensure an adequate core flow coastdown from either recirculation loop following a LOCA. In the case where the mismatch limits cannot be maintained during two loop operation, continued operation is permitted in a single recirculation loop mode.
In order to prevent undue stress on the vessel nozzles and bottom head region, the recirculation loop temperatures shall be within 50*F of each other prior to startup of an idle loop. The loop temperature must also be within 50*F of the reactor pressure vessel coolant temperature to prevent thermal shock to the recirculation pump and recirculation nozzles. Sudden equilization of a tempera-ture difference > 100*F between the reactor vessel bottoa head coolant and the coolant in the upper region of the reactor vessel by increasing core flow rate would cause undue stress in the reactor vessel bottom head.
The objective of GE BWR plant and fuel design is to provide stable operation with margin over the normal operating domain. However, at the high power /lo,< ,
flow corner of the operating domain, a small probability of neutron flux limit cycle oscillations exists depending on combinations of operating conditions 1 (e.g., rod pattern, power shape). To provide assurance that neutron flux limit !
cycle oscillations are detected and suppressed, APRM and LPRM neutron flux -
noise levels should be monitored while operating in this region. l (f AHadalues. Finalv41ues tn be determined during Startuo Testino based onb g e threshold THERMAL POWER and recirculation loop flow which will sweep the T cold water from the vessel bottom head preventing stratification.
CLINTON - UNIT 1 B 3/4 4-1
Attachmsnt 3 to U-601118 Pags 29 of 87 PACKAGE NUMBER 4 Description and Justification of Proposed Change This proposed change is an administrative type of change to add clarifying information to the existing CPS instrumentation Technical Specifications. Two changes are actually proposed, but each affects common instrumentation while both provide additional detail to clarify existing requirements.
The first proposed change is requested to clarify the divisional assignment for the reactor vessel water level and drywell pressure instruments listed on Technical Specification Table 3.3.2-1, items 1.c and 1.f, and Table 3.3.3-1, items C.1.a. C.1.b and C.1.c. This is consistent with other instrumentation for which the divisional assignment was specified (items 1.b and 1.e of Table 3.3.2-1)* and helps to emphasize that some of the instrumentation for High Pressure Core Spray System (RPCS) is associated with two divisions. The proposed change is indicated on the attached marked-up pages and is further explained below.
The channels or trip functions affected by the proposed change provide an isolation trip and they also provide an Emergency Core Cooling System (ECCS) actuation trip. These particular channels are associated with the actuation of HPCS and provide for automatic isolation of the associated test return line. Although HPCS is the Division III ECCS, the channels providing the automatic trip function are located within the Division III and Division IV Nuclear Systems Protection System (NSPS) cabinets or circuitry. Currently, the phrase, "(ECCS Division III)," is inserted adjacent to the functional description specified for the applicable channels in Table 3.3.2-1. It has been determined that specifying "(HPCS - NSPS Div. III and IV)" is more accurate as it indicates that some of these channels are in (NSPS) Division III and some are in (NSPS) Division IV even though HPCS is generally considered to be a Division III ECCS. A similar change is proposed for Table 3.3.1-1 by adding note (g) as shown.
It should be noted that Division IV instruments were taken into account when the Technical Specifications were developed and are a part of the Minimum Operable Channels Per Trip System requirement. They have always been taken into account in the Clinton surveillance procedures. The proposed change, therefore, does not reflect a new requirement and does not change the intent of the affected Technical Specifications or the manner in which they have always been implemented.
- The affected instrumentation performs an isolation function upon a trip condition and so is appropriately listed in the Primary and Secondary Containment Isolation section of the noted Table (Table 3.3.2-1 CRVICS Instrumentation). Because several "Reactor Vessel Water Level-Low Low, Level 2" and "Drywell Pressure-High" channels or trip functions are listed in this section of the Table, clarifying information was provided to distinguish, for example, one "Drywell Pressure-High" trip function from another.
. . i Attachmsnt 3 I to U-601118 I Page 30 of 87 The second proposed change would provide clarification of the combinational logic scheme for the Reactor Vessel Water Level-Low, Low l Level 2 and Dyrwell Pressure-High channels. (Table 3.3.2-1, items 1.c j and 1.f, and Table 3.3.3-1, items C.1.a and C.I.b.) This enhancement is requested to ensure that the corresponding ACTION statements are l properly followed if one or more of the affected channels is declared l J
inope rable .
The logic scheme is unique in that although the protective action (trip) is effected upon either a high drywell pressure or' low reactor water level condition, the combinational logic is different than other one-out-of-two-twice logic schemes. The logic scheme is shown on attached Figure 7.3-8 from the CPS FSAR. Furthermore, for the isolation function, no outboard or inboard trip system configuration exists because. the protective action only closes the single test return line valve for HPCS within ECCS Division III. Clarification is therefore desired to specify how the term "trip system" applies to this configuration with respect to the ACTION statements presently specified in the Technical Specifications.
IP proposes that notes with the following wording be added to Tables 3.3.2-1 and 3.3.3-1 of the CPS Technical Specifications:
Four reactor vessel water level (drywell pressure) trip channels are logically combined in a one-out-of-two-twice configuration.
For the purposes of the associated ACTION, each one-out-of-two logic is defined as a separate trip system.
Separate notes, one for the drywell pressure channels and one for the reactor water level channels, are proposed to avoid confusing the logic with other one-out-of-two twice schemes in which drywell pressure channels and reactor water level channels are alternately combined within the one-out-of-two logics such as exists for the containment isolation logic and ECCS Division 1 and 2 actuation logic. The Minimum OPERABLE Channels Per Trip System requirement was based on the existing logic configuration. The proposed change therefore does not change the intent of the Technical Specification and is proposed only for the purpose of clarifying existing requirements.
Basis For No Significant Hazards Consideration for Change (1)
According to 10CFR50.92, a proposed change to the license (Technical Specifications) involves no significant hazards consideration if operation of the facility in accordance with the proposed change would not (1) involve a significant increase in the probability or ,
consequences of an accident previously evaluated, or (2) create the possibility of a new or different kind of accident from any accident previously evaluated, or (3) involve a significant reduction in a margin 4
of safety.

Attachm:nt 3 to U-601118 Page 31 of 87 (1) The proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated because this change in merely administrative in nature and does not affect any accident analyses. The intent and implementation of the affected Technical Spacifications remains unchanged.
(2) The proposed change does not create the possibility of a new or different kind of accident from any previously evaluated because this change is administrative and is consistent with plant design.
(3) The nroposed change does not involve a significant reduction in a margin of safety because this is an administrative enhancement to operation that provides clarifying information consistent with plant design and the intent of the affected Technical Specification. The troposed change does not reflect any physical changes to the corresponding plant instrumentation. The proposed change therefore does not affect any margin of safety.

PACKAGE NUMBER 5 Description and Justification of Proposed Change Illinois Power (IP) is requesting a change to Clinton Power Station (CPS) Technical Specifications to remove the isolation requirements for isolating the Containment Monitoring (CM) and Process Sampling Systems (PS) upon receiving a Containment Building Exhaust High Radiation signal. This will require changes to Technical Specifications 3/4.3.2 (Table 3.3.2-1 item 1,h, lable 3.3.2-2 item 1.h, Table 3.3.2-3 item 1.h, and Table 4.3.2.1-1 icem 1.h) and 3/4.6.4 (Table 3.6.4-1) in accordance with the attached marked-up pages from the CPS Technical Specifications.
The current Technical Specifications require that the CM and PS systems automatically isolate from a Containment Building Exhaust High Radiation Signal. This trip function is required to be operable in OPERATIONAL CONDITIONS 1, 2, and 3, when handling irradiated fuel in the primary or secondary containment, during CORE ALTERATIONS, and during operations with a potential for draining the reactor vessel.
IP requests deletion of these requirements for the following reasons:
- 1) The CM and PS systems are designed to be operable at post-accident radiation levels. The CM and PS systems are closed loops and have small diameter (3/4 inch) containment penetrations, and they will isolate on a Loss of Coolant Accident (LOCA) signal. The LOCA isolation function will not be affected by this proposed change.
- 2) There are no regulatory bases or engineering justification for isolation of the CM and PS systems upon a Containment Building Ventilation Exhaust High Radiation signal. Discussionc with the Architect Engineer (Sargent and Lundy) indicate that addition of this isolation logic was an overconservative application of regulatory requirements regarding containment isolation capability.
Regarding the marked-up pages, the proposed change deletes the CM/PS isolation function as described so there would no longer be any need to distinguish the CM/PS isolation function (currently part (2) of item h]
from the VR/VQ isolation function [ currently part (1)). Therefore, "Containment Building Exhaust Radiation - High" adequately describes the isolation function since it would be understood that this isolation function only applies to the affected VR/VQ valves. That is, items (1) and (2) may be deleted because there would no longer be any need to subdivida item h. All of the remaining information lef t for item h on Tables 3.3.2-1, 3.3.2-2 and 3.3.2-3 applies to the "Containment Building Exhaust Radiation - High" description and should be brought into line with these words with respect to their vertical position on the tables.

According to 10CFR50.92, a proposed change to the license (Technical-Specifications) involves no significant hazards consideration if operation of the facility in accordance with the proposed change would not (1) involve a significant increase in the probability or consequences of an accident previously evaluated, or (2) create the possibility of a new or different kind of accident from any accident previously evaluated, or (3) involve a significant reduction in a margin of safety.
(1) The proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated because the capability for automatic isolation of the CM and PS systems in response to a LOCA remaina unchanged. Furthermore, the CM and PS systems are designed to be operable and intended to be used under post-accident radiation conditions. Both of the systems are closed loops outside containment and have very small diameter (3/4 inch)containmentpenetrations.
(2) The proposed change does not create the possibility of a new or different kind of secident from any &ccident previously evaluated because the proposed change is applicable only to the design basis established for isolation of the ?S and CM systems with respect to design basis accidents previously evaluated. The proposed change involves no other design changes or introduces any new modes of ,
operation that would require evaluation of an accident not previously evaluated.
(3) The proposed change does not involve a significant reduction in a margin of safety since the original system design has been determined to be an overconservative application of the i requirements of NUREG 0737, section II.E.4.2. l

Attcchz:nt 3 to U-601118 Page 54 of 87 PACKAGE NUMBER 6 Description and Justification of Proposed Change This proposed change affects Technical Specification 3.3.2 (Table 3.3.2-1, item 1.g and Table 4.3.2.1-1 item 1.g) which requires the Containment Building Fuel Transfer Pool Ventilation Plenum Radiation Monitors (1RIX-PR008A-D) to be operable when handling irradiated fuel in primary or secondary containment, during CORE ALTERATIONS and operations with a potential for draining the reaesor vessel (note "f"), and during OPERATIONAL CONDITIONS 1, 2, and 3 (Power Operation, Startup and ilot Standby, respectively). Illinois Power requests that this Technical Specification be changed to be consistent with the intended purpose of these monitors by requiring operability when handling irradiated fuel in the primary containment (building) during CORE ALTERATIONS and operations with the potential for draining the reactor vessel. ACTION 29 associated with OPERATIONAL CONDITIONS 1, 2, and 3 should also be deleted.
Illinois Power proposes adding an additional note (if) to Tables 3.3.2-1 and 4.3.2.1-1 to replace the current "f" note in the respective "APPLICABLE OPERATIONAL CONDITIONS" and "0PERATIONAL CONDITIONS IN WHICH SURVEILLANCE REQUIRED" columns for the Containment Building Fuel Transfer Pool Ventilation Plenum Radiation Monitors. The note reads as follows:
f f When handling irradiated fuel in the primary containment (building) and during CORE ALTERATIONS and operations with a potential for draining the reactor vessel.
As required by NUkEG-0800 (The Standard Review Plan) Subsection 15.4.7.III.4, process radiation monitors 1RIX-PR008A-D are provided only to mitigate the consequencas of a fuel handling accident inside the primary containment by providing prompt radiation detection and automatic containment isolation capability. These monitors are located as far upstream in the HVAC exhaust system as practical in order to ensure adequate response for prevention of a puff release of radioactivity due to a opent fuel accident from leaving the containment.
Two other process radiation monitors (Containment Building Exhaust and Containment Building Continuous Containment Purge Exhaust) are downstream of 1RIX-PR008A-D and monitor the entire containment exhaust air flow. Thus, the function of monitoring containment exhaust air under all normal operating conditions is adequately performed by two fully redundant safety-grade radiation monitoring systems. Therefore, IRIX-PR008A-b are not required for the purpose of monitoring containment exhaust air during conditions other than when fuel handling is in progress. The possibility of having a fuel handing accident inside the containment is directly related to fuel handling operations but has no direct relationship to plant operating conditions. Regardless, FSAR section 9.1.2.1.2 states that the upper fuel storage pool will contain no fuel during power operations; therefore, no fuel handling can take place inside the primary containment during OPERATING CONDITIONS 1, 2, or 3. CPS Procedure 3001.01, APPROACH TO CRITICALITY, step 6.5, ensures that this co=mitment is fulfilled.
l Attechn:nt 3 ;
to U-601118 l Pcge 55 of 07 l i
The proposed "##" note is a revision of the original "f" note in which the words "or secondary containment" were deleted and "(building)" was inserted. This was done because the affected monitors, i.e., the Containment Building Fuel Transfer Pool Ventilation Plenum radiation monitors, which are located inside the containment building, would not respond or provide the protective action in response to a fuel handling accident inside secondary containment (i.e. , the fuel building) . They, therefore, should not be required to be OPERA 3LE'when handling irradiated fuel in the secondary containment (as opposed to the primary containment).
Maintaining these instruments operable is relatively labor intensive.
Detector calibration, and therefore containment entry, is required every six months to meet Equipment Qualification requirements. Requiring these monitors to be operable when no fuel handling is in progress in the areas monitored by these instruments takes resources away from other -
tasks.
Basis For No Significant Hazards Consideration According to 10CTR50.92, a proposed change to the license (Technical Specifications) involves no significant hazards consideration if operation of the facility in accordance with the proposed change would not (1) involve a significant increase in the probability or consequences of an accident previously evaluated, or (2) create the possibility of a new or different kind of accident from any accident previously evaluated, or (3) involve a significant reductirn in a margin of safety.
(1) The proposed change does not involve a significant incresse in the probability or consequences of an accident previou91y evaluated because the affected radiation monitor will supply the necessary containment isolatien signals following a fuel hs.ndling cecident ,
inside the containment building. Other designated radiation monitors are the primary instruments for initiscing a containment isolation during GPERATING CONDITIONS 1, 2, and 3. Operability of these instruments is not affected by this change.
(2) The proposed cht.nge does not create the posribility of a new or different kind af accident from any previously evaluated because this change involves changing the operability requirements only for the noted monicor. The monitor will be r2 quired to be operable only when it is needed to perform its deoign function consistent with the accident (fuel handling accider.t inside the primary containment building) for which its rerponse is required. No other changes in piant operation are required. This change will make the Technical Specifications reflect the actual plant design and will ,
not change the plant's physical configuration.
(3) The propos2d change does not involve a significant reduction in the margin of safety because while in OPERATING CONDITIONS 1, 2 and 3 !
sufficiene redundant process radiation instrumentation is available to initis,te a containment isolation when a high radiation condition exists. The proposed change does not impact the operability or trip setpoints for these instruments.

. o Attcchsent 3 to U-601118 Page 63 of 87 PACKAGE NUMBER 7 Description and Justification of Proposed Change This proposed change is to clarify Technical Specification 3/4.7.2 "Control Room Ventilation System" by adding an Equipment Identification Number (EIN) to Specification 4.7.2.h. This will ensure that the visual inspection (to verify integrity of the noted flexible connection) is performed on the correct fan and thereby eliminates any possibility of misinterpretation of the Specification.
It should be noued that although both the OVC04CA(B) and OVC03CA(B) fans are associated with the recirculation filter system, the requirement for visually verifying the integrity of the Recirculation Filter Housing flexible connection is applicable only to the OVC03CA(B) fan because that fan is located at the exit of the filter housing. A loss of integrity of the floxible hose connection to the OVC03CA(B) fan could allow unfiltered air to enter the habitability boundary since such air would bypass the filter system. The OVC04CA(B) fan also has a flexible connection, but because it is located upstream of the filter housing, air leaking into the system through this connection would not bypass the filter system. In-leakage through the latter connection is a component of the leakage required to be verified as required by the first part of this surveillance requirament. That is, the latter connection is alresdy included within the test scope of the test described in the first part of Specification 4.7.2.h and therefore does not need to be visually inspected like the OVCO3CA(B) f an.
Basis For No Significant Hazards Consideration According to 10CFR50.92, a proposed change to the license (Technical Specifications) involves no significant hazards consideration if operation of the facility in accordance with the proposed change would not (1) involve a significant increase in the probability or consequences of an accident previously evaluated, or (2) create the possibility of a new or different kind of accident from any accident previously evaluated, or (3) involve a significant reduction in a cargin of safety. l (1) The proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated because this proposed change is merely a clarification of an existing Specification and does affect any accident analyses.
(2) The proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated I
because no design changes or new modes of operation are affected by the proposed change. The scope of the proposed change is strictly ;
limited to clarifying an existing Specification. No new accident l scenario is created.
(3) The proposed change does not involve a significant reduction in a margin of safety because this is an administrative change clarifying the intent and scope of an existing Specification and does not affect a margin of safety. l

. 1 Attcchesnt 3 to U-601118 Page 68 of 87 PACKAGE NUM3ER 8 Description and Justification of Proposed Change The purpose of this proposed change to the CPS Technical Specifications is to revise the Trip Setpoint. Allowable Value and instrument-zero point specified for the suppression pool water level instrument associated with Table 3.3.3-2, (item C.1.e) and Table 3.3.5-2 (item d).
ISee attached marked-up pages 3/4 3-41, 3-42, and 3-61 from the CPS Technical Specifications). Initial performance of the plant calibration procedure revealed that, due to an error in the installation design, the desired calibration range for the noted instrument loop did not properly correspond to the calibration range of the installed transmitters. The effect of this was that the values indicated in inches (water column) by the analog trip modula (ATM) for the Trip Setpoint and A11cvable Value did not match the values specified in inches (water column) in the Technical Specifications. This was temporarily resolved by inserting a note into the calibration procedure acknowledging the apparent discrepancies. This reaolution was allowed because the instrument would still trip at the water level (in terms of elevation) for which the trip was required to occur.
A modification was originally proposed to relocate the transmitter, but it was decided that the problem could be remedied crithout relocating the sensor by redesignating the instrument-sero point and correspondingly respecifying the associated Trip Satpoint and Allowable Value. The instrvrent would still continue to operate satisfactorily for the minimum range of water level (elevation) required. The effect of redesignating the instrument-zero point is to shift the ATM-indicated water level values by 15 inches. The Technical Specification thus needs to be changed to reflect the ATM-indicated values. That is, under.the revised Technical Specification, the ATM-indicated values for the Trip Setpoint and Allowable Value would match the values indica:ed by the Technical Specification Table.
The change only electronically affects the instrument loop indication and does not change the design basis for the trip function. That is, the actual suppression pool level (in terms of elevation) at which the trip function should occur will remain unchanged.
Basis for No Significant Hazards Consideration According to 10CFR50.92, a proposed change to the license (Technical Specifications) involves no significant hazards consideration if operation of the facility in accordance with tne proposed change would not (1) involve a significant increase in the probability or consequences of an accident previously ev.luated, or (2) create the possibility of a new or different kind of accident from any accident previously evaluated, or (3) involve a significant reduction in a margin of safety.

to U;601118- l Page 69 of 87 l (1) The proposed change does not involve s'significant increase in the probability or consequences of an accident previously evaluated ,
because the proposed changes do not change the actual level (in terms of elevation) at which the affected instrument is designed to trip. That is, the analytical basis from which the Trip Setpoint and Allowable Value were determined remains unchanged.
(2) It has been dstermined that the proposed change does not create the .
L possibility of a new or different kind of accident from any previously evaluated because no changes to plant operatioa or ~
changes to the design function of the instrument are proposed. No consideration of new or additional accident scenarios is required. 9 (3) The proposed change does not involve a reduction in a margin of safety because the proposed change does not change the relationship .
2 between the Trip Setpoint. Allowable Value, instrument-sero . point l and analytical limit. The design basis for the Trip Setpoint is t
unchanged. The proposed change to the Technical Specification reflects a change'to the instrument loop that will more closely match the sensor range to the range indicated by the trip unit thus ,
enhancing satisfactory operation of the instrument loop and satisfactory performance of the instrument loop calibration.

o s Attachmtnt-3 to U-601118 Page 83 of 87 PACKAGE NUMBER 11 Description and Justification of Propose'd Change Illinois Power (IP) is requesting a change to Technical Specification Table 3.3.2-2, item 2.h to increase the Trip Setpoint and Allowable Value for Turbine Building Temperature Monitors 1E31-N563A, B, C, and D.
The proposed change would increase the Trip Setpoint from $ 131.2*F to
$143.2*F and the Allowable Value from 6138'F to S150*F.
Instruments 1E31.-N563A, B, C, and D monitor ambient temperatures in the Turbine Building Steam Tunnel between columns K-N, rows 109-116, and ,
elevations 762'-0" and 796'-0". These temperature monitors initiate a mair steam line isolation when the ambient temperature exceeds the trip setpoint. (The main steam line isolation will subsequently initiate a -
reactor scram when the reactor mode switch is in the RUN position.)
According to the design basis provided by the architectural engineer (AE) for Clinton, a maximum normal operating temperature of 122*F was assumed for the setpoint calculations. The temperature increase resulting'from a steam leak equivalent to 25 spa after two minutes was determined to be 16*F. These values, together with a drift allowance of 16.8'F, were included in the instrument setpoint calculations performed in accordance with Regulatory Guide 1.105, "Instrument Setpoints." ,
These calculations established the current'setpoint of 131.2*F for the ,
1E31-N563A, B, C and D instruments:
Maximum normal operating temperature = 122*F i Temperature increase for a 25 gpm leak @ 2 min. = 16'F Allowable value = 138'F Drift Allowance = - 6.8'F i
Resultant setpoint = 131.2'F The AE noted that radiological considerations were not included in the determination of this setpoint since it was not the bounding concern in this situation and since radiation monitors are installed in the exhaust ductwork from the tunnel and in the common station vent to which the exhaust is directed. (The exhaust process radiation monitor is designed i to detect an airborne concentration of 0.1 times the Maximum Permissible {
Concentration (MPC) and to alarm at 1.0 MPC to ensure that 10CFR20 limits are not exceeded at the restricted area boundary).
Operating experience to date has shown that the ambient temperature that typically exists in the area of the subject instruments is 120-125'F when the reactor is operating at 90-100% rated thermal power. Since Clinton has not yet operated at a sustained full reactor power level during summer conditions, the peak normal oper.cing temperature in the applicable area may be higher. If a drift of - 6.8'F from the currently specified setpoint of 131.2'F is assumed, resulting in an effective l l setpoint of 124.4'F, an unwanted trip or at least a very small operating j l margin is practically ensured. !

to U-601118 Page 84 of 87 Illinois Power has determined that increasing the current trip setpoint
, and Allowable Value by 12'F will provide an adequate operating margin. .
I A 12"F increase is based on a re-evaluation of the setpoint using the same methodology as before except that the new setpoint corresponds to a l steam leak equivalent to 25 gpm after 5 minutes. As noted earlier, the !
original setpoint was based on a 25 gpm equivalent leak for 2 minutes, f
The time limit for the assumed leakage rate is established through sound engineering judgment by striking a balance between the minimum time needed before a leak can be detected without causing an inadvertent or unwanted isolation and the maximum time allowed for the leakage ;
condition to be recognized. A leakage time of 5 minutes is still considered acceptable and consistent with this intent. ,
The resultant Allowable Value of 150*F is justified for the following l reasons:
(1) Potential unnecessary channel trips due to high localized ambient temperature (especially caused by a reduction in or a loss of non-safety area cooling capacity) should be reduced. This will reduce the number of cycles and challenges to the Main Steam Isolation Valves, Safety / Relief Valves, Primary Containment, and other safety systems caused by the resultant inadvertent main steam line isolations and subsequent reactor scrams.
(2) Safety related components (Leak Detection sensors, pressure and limit switches) located in the Turbine Building Steam Tunnel between columns K-N and rows 109-116, from elevation 762'-0" to 796'-0" were evaluated for the higher temperature of 150'F. The results of this evaluation were that there were no adverse effects upon the affected components or structures. Therefore, localized temperatures of 150*F cause no adverse environmental impact on safety-related systems, structures, or components.
(3) Radiological protection is still provided by the Process Radiation Monitoring System and associated alarm functions.
(4) The assumed leakage rate of 25 gal / min. (which remains unchanged) is within the capacity of the Feedwater delivery system, which is designed to provide 115.5% of the full power feedwater flow of approximately 29,300 gal / min.
(5) The main steam line turbine building temperature monitors associated with the main steam line isolation trip function are located in each of five different areas of the turbine building (four sensors per location) near the main steam lines. The proposed change is applicable to only one of these areas. No changes are proposed at this time for the setpoints associated with the instruments in the other four areas.

Attachmsnt 3 to U-601118 I Page 85 of 87 Basis For No Significant Hazards Consideration According to 10CFR50.92, a proposed change to the license (Technical Specifications) involves no significant hazards consideration if operation of the facility in accordance with the proposed change would not (1) involve a significant increase in the probability or consequences of an accident previously evaluated.' (2) create the possibility of a new or different kind of accident from any accident previously evaluated, or (3) involve a significant reduction in a margin of safety.
(1) It has been determined that the proposed change poses no significant increase in the probability or consequences of an accident previously evaluated because a) localized temperatures of 150*F will cause no adverse environmental impact on systems, structures or components necessary for safe shutdown, (b) the proposed change does not impact the probability of occurrence of a leak, (c) only one of five turbine building areas in the vicinity of the main steam lines is affected by the proposed change, and (d) the trip setpoints for the monitors in the affected area are still based on the leakage rate assumed for the original setpoint and a leakage time determined to be acceptable such that the proposed change does not constitute a significant change in leak detection capability. In addition, the proposed change should decrease the probability of inadvertent main steam line isclations and reactor scrams. Radiation detection will continue to be provided as designed.
(2) The proposed changa does not create the possibility of a new or different kind of accident from any accident previously evaluated
~
because the proposed change introduces no new modes of operation, failure modes or changes to any equipment other than the affected monitors (for which the effects on the applicable accident scenarios have been evaluated).
(3) The proposed change does not involve a significant reduction in a margin of safety because the leak detection capability provided by the affected monitors will not be significantly reduced by the proposed change to the monitor setpoints. Other temperature j monitors, as well as the associated radiation monitors, will not be affected at all, l
