v SURVEILLANCE SR 3.7.2.1 REQUIREMENTS This SR verifies that MSIV closure time is s 5 seconds. The MSIV closure time is assunied in the accident and containment e analyses. This Surveillance is normally performed upon o returning the unit to operation following a refueling
' . outage. Based on ASME Code Section XI (Ref. 5), the MSIVs 9 are not closure time tested at power.
b ni The Frequency is in accordance with the Inservice Testing Program. This test is conducted in MODE 3 with the unit at h operating temperatore and pressure. This SR is modified by
@! a Note that allows entry into and operation in MODE 3 prior to performing the SR. This allows a delay of-testing until MODE 3. to establish conditions consistent with those under which the acceptance criterion was generated.
SR 3.7.2.2 1his SR verifies that each MSIV can close on an actual or simulated actuation signal. This Surveillance is normally performed upon returning the unit to operation following a refueling outage. The frequency of MSIV testing is every 18 months. The 18 month Frequency for testing is based on 7 $,
s the refueling cycle. Operating experience has shown that V % these components usually pass the Surveillance when O performed at the 18 month Frequency. Therefore. this 8I Frequency is acceptable from a reliability standpoint. 1

DISCUSSION OF CHANGES TO CTS ITS SECTION 3.7 - PLANT SYSTEMS A, CTS SR 4.7.1.3.1 and SR 4.7.1.3.2 are conditional dependin on whether the CST or Essential Service Water (SX) System is the supp y source for the AF pumps. CTS 3.7.1.3 Action b directs the demonstration of the SX System as operable for a backup supply to AF. ITS SR 3.0.1 indicates that SRs do not have to be performed on inoperable equipment and ITS 3.7.6 Condition A includes the requirement to demonstrate by administrative means the operability of the backup system. which in this case would be the SX System. Therefore. deletion of the references to CST or SX System as the source for AF is an administrative change associated with ITS format. During this reformatting, no technical changes (either actual or interpretational) were made to the TS. unless identified and justified.
Aa CTS 3.7.1.5 Mode 1 Actions address an inoperable but open MSIV. Byron and Braidwood are not licensed for three loo) operation. Therefore indefinite operation would not permitted wit 1 a closed MSIV. Therefore, the deletion of the words "but open" is administrative in nature. There is no technical change (either actual or interpretational) made.
The CTS Mode 1 Actions include a requirement to be in Hot Standby (Mode
- 3) within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in Hot Shutdown (Mode 4) within the following 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> if an inoperable MSIV is not restored to OPERABLE r status. Once the unit is in Mode 2 (within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />), the CTS Action for
'j, Modes 2 and 3 would apply. CTS 3.7.1.5 includes the same Actions for Modes 2 and 3. ITS. Conditions A and B are associated with Mode 1. while Conditions C and D are associated with Modes 2 and 3. In ITS if Condition B was entered (Be in Mode 2). as soon as Mode 2 was reached Condition D would be applicable and would require shut down to Mode 4 ,
(per the Required Actions of Condition E). Therefore the requirements I of CTS Actions are covered by ITS 3.7.2 Actions and this change is administrative in nature. No technical changes were made to the TS, unless identified and justified.
M' o An CTS 3.7.1.5 Modes 2 and 3 Actions state that the provisions of CTS Specification 3.0.4 are not applicable. In addition CTS SR 4.7.1.5 9 states that the provisions of Specification 4.0.4 are not applicable.
b The CTS requirements allow entry into the Mode of Applicability to M perform the surveillance to verify perability. The CTS has been i revised to delete the reference to pecification 3.0.4. and 4.0.4. This D has been replaced with the Note for ITS SR 3.7.2.1 and SR 3.7.2.2 which g requires the SRs only in Modes 1 and 2. ITS relies upon the guidance of SR 3.0.4 and wording of the SRs to allow the performance of these SRs in Mode 3. This is merely a reformatting of existing requirements. During this reformatting, no technical changes (either actual or interpretational) were made to the TS unless identified and justified.

Ma CTS LCO 3.9.11 APPLICABILITY states "Whenever irradiated fuel assemblies are in the storage 2001." ITS LC0 3.7.15 APPLICABILITY revises the CTS by stating. "W1enever fuel assemblies are stored in the g spent fuel pool ." The CTS APPLICABILITY was only when irradiated fuel 3
was stored in the pool. The ITS is more restrictive since the y elimination of the word " irradiated" now requires that the APPLICABILITY g- is for anytime new or irradiated fuel is in the pool. This change is consistent with NUREG-1431.
H, g (Byron Only) CTS LCO 3.7.5 Action e.l.a requires restoration of the level switch to OPERABLE status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or verification that the UHS basin level is greater than or equal to 90% within the next hour
! after the time one UHS cooling tower b min switch is determined to be
! inoperable. ITS 3.7.9 Required Acti ? ' requires this action to be completed within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> (versus R %% in the CTS) after the
! Z determination that one SX makeup pump 1s inoperable, whether due to an L > -inoperable basin level switch or other cause. The reduction in j g Completion Times for the inoperable tower basin switch is a more restrictive change to the requirements.that currently apply to the facility.
~
l Ma (Byron Only) CTS LCO 3.7.5 Action e permits contin'ued' operation for an 7 .s indefinite period with one cooling tower basin level switch ino)erable.
i ITS 3.7.9 Required Action C.2 requires verification of an operaale associated makeu) source for the UHS cooling tower basin within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> and C.3 limits t1e time the plant may continue to operate with one basin l
g level switch inoperable. RA C.3 limits plant operations to 7 days if both units are in Mode 1. 2. 3. or 4 and 14 days if one unit is in
> Mode 5, 6. or defueled with an inoperable SX makeup aump. This limit on
! k the amount of time that a unit may operate with one JHS cooling tower basin level switch inoperable is an additional restriction on plant operations.
Mu (Byron Only) CTS LC0 3.7.5 Action e.2.a indicates that the provisions ,
of Specification 3.0.4 are not a]plicable when both UHS cooling tower l- basin level switches are inoperaale. ITS 3.7.9 Action D, which would be 2 applicable if two UHS cooling tower basin level switches are inoperable.
does not provide a similar allowance. This is an additional restriction j k on plant operations.

STS SR 3.6.3.1 and associated Bases discussions ITS 3.6.3 Action D ITS SR 3.6.3.1 and associated Bases discussions STS 3.6.3 RA E.1, E.2 and E.3 have been revised in ITS 3.6.3 ACTION D to delete the option ofisolating a penetration flow path with a purge valve not within the leakage limits and associated ras. The only option is the current licensing basis of restoring the valve to OPERABLE status in 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or begin an orderly plant shutdown. Also, the STS SR 3.6.3.1 exception for opening one purge valves while in Condition E is deleted. Justification B.3, Bases B.3 and Bases P.13 state this exception is already accommodated in Condition A Required Actions. This is not understood because if a purge valve is leaking, then Condition A cannot be entered. Thejustification must be further explained. Comment: Provide additional discussion and justification for this CTS change.
Comed Response to issue-Revised Response: Comed's response at the 4/1/98 meeting was to evaluate adopting the NUREG for ITS 3.6.3 Required 7 Action E and SR 3.6.3.1. Comed is retaining the changes associated with ITS Revision A based on current licensing basis.
Original Response: " Condition A" has been changed to " Condition D" in Section 3.6 LCO JFD B3 and Bases JFD B3. The JFDs have been revised to state, "This exception is adequately addressed by Condition D Required Actions, without the necessity for the complexity introduced by this exception." The exception in SR 3.6.3.1 is unnecessary since SRs do not f
y have to be performed on inoperable equipment or components, i.e., when Condition D is entered.

- __ _ -_ _ _ . . . _ _ _ . . ~ . _ . . _ _ _ _ . . _ - . l l DISCUSSION OF CHANGES TO CTS i ITS SECTION 3.3 INSTRUMENTATION ( 3 k* g.! An By letter dated October 6. 199S. Comed received License Amendment
; 104 (Byron) / 96 (Braidwood) which changed CTS Table 3.3-4 Functional :
Unit 6.g. Auxiliary Feedwater Pump Suction Pressure - Low. Trip Setpoint I and Allowable Value (and LC0 3.7.1.3 to raise the CST level, which is addressed ir another ITS Section). The clouded portions of the CTS l markup reflect this change. This change was requested as a result of 1 l Comed identifying an operability concern involving the postulated i l failure of Safety Category II CST piping in the turbine building during i a seismic event. This postulated failure of the non-seismic piping l N l could eventually result in atmospheric pressure (14.7 psia) in the AF ' C suction line. This would minimize the potential for an automatic switch
' over of the AF water supply from the CST to SX water, since the previous 9 Trip Setpoint value was 14.1 psia (1.22" Hg vac). In response to the N operability concern, the minimum administrative CST level and the 1 M physical height of the CST were raised. Additionally, the above I a
mentioned CTS License Amendment increased the AF pump Suction Pressure - 1 i Low Trip Setpoint and Allowable Value to greater than or equal to 1 3 18.1 psia and 17.4 psia, respectively. as well as increasing the minimum required CST level. These setpoints ensure that the automatic switch , over of the AF supply would occur when required, j An CTS Table 3.3-1 Actions 10 and 13 are revised (see also DOC L ) to include a Note precluding a MODE change into MODE 5 with the kod Control System capable of rod withdrawal or all rods not fully inserted for ITS iO Functions 18. 19. and 20. This Note is inserted in conjunction with a revision to LCO 3.0.4 (refer to Section 3.0 DOC ls). As a result of the-change to LCO 3.0.4 all ITS Actions were evaluated for individual acceptability of this change. Based on this evaluation where MODE change restrictions were determined to be required in MODES 5 and 6. or - W in MODES 1. 2. 3. and 4 during unit shutdown Notes containing the
> appropriate MODE change restrictions are added to the individual
$. Specifications. The Note that is added to ITS 3.3.1 Condition C is a result of this evaluation. Since the technical aspects of this change are addressed in Section 3.0. this change is considered administrative in this Section.
N A3 CTS and STS use the term " Intermediate Range Neutron Flux" for the P-6 0 RTS interlock. In ITS, the P-6 interlock is referred to as " Source
.l Range Block Permissive." This change was made so that the TS agree with 6 plant design and terminology. The Byron /Braidwood Main Control Room g annunciator and Bypass Permissive Panel windows, as well as plant procedures, reference " Source Range Block Permissive" for the P-6 4 interlock. This change is considered editorial in nature and does not g involve a technicai change (either actual or interpretational) to the TS.
BYRON /BRAIDWOOD UNITS'1 & 2 3.3 Sa 10/27/98 Revision 0
DISCUSSION OF CHANGES TO CTS ITS SECTION 3.3 INSTRUMENTATION L lb l A3 CTS Table 2.2-1 for Functional Unit 19.b (P-7) lists the inputs into
,c l P-7. namely Functional Unit 19.b.1 (P-10) and Functional Unit 19.b.2 (P-13). Functional Unit 19.b.1 and Functional Unit 19.b.2 have been 7.! deleted since they are redundant to CTS Table 2.2-1 Functional Units t ; 19.d (P-10) and 19.e (P-13). The Allowable Values in CTS Table 2.2-1
.d ! for Functional Unit 19.d and Functional Unit 19.e have been retained in j ITS Table 3.3.1-1 for Function 17.d (P-10) and Function 17.e (P-13).
% i During this reformatting. no technical changes (either actual or 1 interpretational) were made to the TS unless they were identified and justi fied. The change is consistent with NUREG-1431.
l A3 In CTS Table 3.3-3. Functional Unit 1.d for " Pressurizer Pressure-Low l (Above P-11)" and Functional Units 1.e and 4.d for " Steam Line Pressure-Low (Above P-11)" have an Applicability of Modes 1. 2. and 3# where footnote (#) states that the trip function may be blocked in Mode 3 below the P-11 setpoint. Functional Unit 4.e for " Steam Line Pressure Negative Rate - High (below P-11)" has an Applicability of Mode 3## where footnote (##) states that the trip function is automatically blocked above P-11 and may be blocked below P-11 when the steam line pressure-low SI is not blocked. In ITS Table 3.3.2-1. Function'1.d for " Pressurizer Pressure - Low" and Function 1.e for " Steam Line Pressure - Low" have an Applicability of (c) v Modes 1. 2. and 3(a) where footnote (a) states above the P-11 interlock, Function 4.d.1 for " Steam Line Pressure - Low" has an Applicability of D' Modes 1. 2(g), and 3(a)(f)(g) where footnote (a) states above the P-11 interlock. footnote (g) states except when all MSIVs and MSIV bypass y ti valves cre closed, and footnote (f) states below the P-11 interlock with Qg Function 4.d.2 not enabled. Function 4.d.2 for " Steam Line Pressure - tj Negative Rate - High" has an Applicability of Mode 3(d)(g) where footnote (d) states below the P-11 interlock with Function 4.d.1 blocked. This change is necessary due to the reformatting of the requirements j contained in the ITS. This change is perceived as the intent of the CTS i wording, is considered editorial in nature and does not involve a technical change (either actual or interpretational) to the TS unless otherwise noted. An CTS Table 4.3-1 Functional Units 7 through 16. and CTS Table 4.3-2 Functional Units 1 through 7 and 9. have been revised by a Note stating. 3 "This Surveillance shall include verification that the time constants are adjusted to the prescribed values." This Note is consistent with
'h C-- current operating practices and is therefore consistent with NUREG-1431.

Pg ITS SR 3.3.1.11 Bases is revised to add " ..and obtaining the detector plateau curves, evaluating those curves. and comparing the curves to the manufacturer's data." This change provides a more accurate description of how this SR is accomplished. l Pu NUREG-1431 SR 3.3.1.16 Bases states. "The analyses model the overall or total elapsed time, from the point at which the parameter exceeds the trip setpoint value at the sensor to the point at which the equipment i reaches the required functional state (i.e., control and shutdown rods i
-m fully inserted in the reactor core)." The statement. "(i.e., control
'(R./
) and shutdown rods fully inserted in the reactor core)" is being deleted.
- The ITS Definition for Reactor Trip System (RTS) Response Time specifically states. "The RTS Response Time shall be that time interval from when the monitored parameter exceeds its RTS trip setpoint at the LU channe1 sensor until loss of stationary gripper coil voltage." This u l conflicts with the example provided in the SR, which identifies the l 3 final measurement state as " rods fully inserted." When the stationary o gripper coil voltage is lost the control rods are not yet fully i h- inserted. therefore, this change eliminates potential confusion. and establishes consistency with the Definition. ,

CTS DOCS l 9
i l DISCUSSION OF CHANGES TO CTS ITS SECTION 3.7 PLANT SYSTEMS Au CTS LC0 3.7.1.1 Action a requires restoration of an inoperable MSSV.. NUREG-1431 does not contain the restoration action, but rather relles ; upon the guidance of LCO 3.0.2 which allows the restoration of a 1 parameter within the time limits of the specified Required Actions. The CTS has been revised to delete this restoration action since the option to restore an inoperable component currently exists in the ITS. During l this reformatting, no technical changes (either actual or interpretational) were made to the TS. unless identified and justified. The change is consistent with NUREG-1431 as modifiea by WOG-83. Ay CTS SR 4.7.3.1 requires verification that each valve (manual. power-operated, or automatic) servicing safety-related is in its correct position. The Byron and Braidwood CC System does not include l any automatic valves. Therefore, the CTS Reference to " automatic" does not have any technical meaning and ITS SR 3.7.7.1 does not include the words automatic. Because the ITS SR accurately reflects the design and intent of the CTS requirement. no technical changes were made to the TS. unless identified and justified. Au By letter dated October 15, 1998, a revision to the Byron and Braidwood CTS for the Nonaccessible Area Exhaust Filter Plenum Ventilation System was received (Amendment # 105 for Byron / Amendment # 97 for Braidwood). Any revisions to the request as a result of the conversion to the ITS are annotated and justified separately. A. A note is added to CTS LCO 3.7.7 (ITS LCO 3.7.12) that allows the Nonaccessible Area Exhaust Filter Plenum Ventilation System alignment requirement to be suspended intermittently under administrative controls for purposes of train realignment. The Nonaccessible Area Exhaust Filter Plenum Ventilation System is required to have two trains aligned for operation and one train aligned in standby because the system design cannot support operation of three trains simultaneously. This note is added to clarify that during realignment of the system there may be a short time period when three inlet dampers may be open or two inlet dampers may be closed. This is an administrative change with no impact on safety because the clarification provided by the Note is consistent with the existing interpretation of the CTS. l lV BYRON /BRAIDWOOD UNITS 1 & 2 3,7 11 10/29/98 Revision Q \ .- .

An The Explosive Gas and Storage Tank Radioactivity Monitoring Program ! e r includes a clarification statement denoting that the provisions of (R 3.0.2 and SR 3.0.3 are applicable to this Program. This statement of applicability clarifies the allowance for surveillance frequency extensions and allowance to perform missed surveillances. This change
-j is necessary since the CTS requirements. CTS LCO 3.11.1.4 and CTS d
3 LC0 3.11.2.5. are being relocated from the TS, and the program described in ITS Specification 5.5.12 is being added where the statements of ; applicability are generally not applied. Since this change maintains current requirements, it is considered a change of presentation method ' only. During this reformatting, no technical changes (either actual or ! interpretational) were made to the TS unless they were identified and l justified. This change is consistent with NUREG-1431. l
'A 3 CTS 6.2.2.b is being deleted. The requirements of 10 CFR 50.54(m)(iii) !
and 50.54(k) adequately provide for shift manning. These regulations. l 50.54(m)(iii). require. "when a nuclear power unit is in an operational MODE other than cold shutdown or refueling. as defined by the unit's , Technical Specifications. each licensee shall have a person holding a i senior operator license for the nuclear power unit in the control room ) g at all times. In addition to this senior operator, for each fueled i

STS 5.2.2b requirements will be met througl compliance with these regulations and is therefore, deleted from the CTS and not incorporated into the ITS.

A'y The CTS Table 4.4-2 10 CFR 50.72 (b)(2) reporting requirement is deleted. Deletion of the CTS requirement does not change the requirement to report results that satisfy the criteria of 10 CFR 50.72 (b)(2).

l TECHNICAL CHANGE LESS RESTRICTIVE "Soecific" ("L," Labeled Comments / Discussions) _l
' Commonwealth Edison Company (Comed) has evaluated each of the proposed Technical Specification changes identified as " Technical Change - Less Restrictive (Specific)" in accordance with the criteria set forth in
! 10 CFR 50.92 and has determined that the proposed changes do not involve a l significant hazards consideration.
The bases for the determination that the proposed changes do not involve a significant hazards consideration is an evaluation of these changes against each of the criteria in 10 CFR 50.92. The criteria and the conclusions of the evaluation are presented below.
- 1. Does the change involve a significant increase in the probability or consequences of an accident previously evaluated?
Some of the information in the CTS is descriptive in nature and incorporates redundant information as stated in the 10 CFR. Standard Review Plan. Regulatory Guides or other NRC regulations. This redundant information pertains to various equipment. system (s). actions. Programs or surveillances. The NRC has previously approved removing this q redundant information and detail from the CTS to a licensee controlled Cf document. reference the appropriate NRC regulation in a Program, or simply referencing the approariate NRC Standard (i.e. 10 CFR or Regulatory Guide). The NRC 1as agreed that the inclusion of this redundant information in the ITS is not necessary to adequately protect the health and safety of the public. Although this information is being moved or referenced. 10 technical requirements or commitments for compliance are being changed. The only change is that instead of providing this redundant information in the ITS. credit is being taken for the same information and requirements in the appropriate NRC
. Standards. This is considered to be a Less Restrictive change since the information is being removed from the CTS and not being included in the ITS.
This relaxation will not alter the operation of any plant equipment. reduce any Comed commitments to appropriate NRC Standards, nor increase any failure probability for evaluated accidents in the UFSAR. The probability that equipment failures resulting in an analyzed event will occur is unrelated to this change. As such, the probability of occurrence for a previously analyzed accident is not significantly increased.

1 i l l l I i 'n NO SIGNIFICANT HAZARDS EVALUATION l Q ITS SECTION 5.0 ADMINISTRATIVE CONTROLS l 2. Does the change create the possibility of a new or different kind of l accident from any accident previously evaluated? i The proposed change does not involve a physical alteration to the plant. No new equipment is being introduced and no installed equipment is being operated in a new or different manner. There is no alteration to the parameters within which the plant is normally operated nor in the setpoints which initiate protective or mitigative actions. No technical change is being proposed to the procedures governing normal plant operation of those relied upon to mitigate a design basis event. l Removing the redundant information and requirements from the CTS and l taking credit for the appropriate NRC Standard (i .e. 10 CFR or l j Regulatory Guides} does not alter any Comed commitments for compliance with the appro]riate NRC Standards nor introduce any new failure modes. In addition, t1e changes do not alter assumptions made in the safety analysis and licensing basis. Therefore, the change does not create the possibility of a new or different kind of accident from any accident previously evaluated.
- 3. Does the change involve a significant reduction in a margin of safety?
,. The margin of safety is determined by the design and qualification of / the plant equipment, the operation of the plant within analyzed limits, \ and the point at which protective or mitigative actions are initiated.
Removing the duplicative information and requirements from the CTS and taking credit for the appropriate NRC Standard (i.e. 10 CFR or Regulatory Guides) does not alter any Comed commitments for compliance with the NRC Standards. The proposed change has no effect on the assumptions of the design basis accident. This change has no impact on the safe operation of the plant. There are no design changes or equipment performance parameter changes associated with this change. No l setpoints are affected, and no change is being proposed in the plant operational limits as a result of this change Therefore. this change does not involve a significant reduction in the margin of safety. l l B'rRON/BRAIDWOOD UNITS 1 & 2 5.0 21d 10/30/98 Revision 0
