- ADDITIONAL INFORMATION COVER SHEET ADDITIONAL INFORMATION NO: Q 3.4.9-3 APPLICABILITY: CP, WC REQUEST: Difference 3.4.17 (Wolf Creek, Diablo Canyon and Comanche Peak)
Comment: TSTF-93 Rev. 3 was approved with a reviewer's note which says that for non-dedicated safety-related heaters which normally operate the frequency is 18 months and for dedicated safety-related heaters which normally don't operate the frequency is 92 days. Each of the plants is asking for the 18 month frequency but it is unclear from the submittals if they meet the criterion. Please provide information demonstrating consistency with the TSTF.
FLOG RESPONSE (original): DCPP and WCGS have two-groups of non-safety related pressurizer backup heaters. The pressurizer heaters, together with the pressurizer spray valves, are used to control RCS pressure.
For DCPP, the NRC recently approved (6/5/98) changing the CTS SR 4.4.3.2 from 92 day to
" Refueling Interval" in L:A 126/124.
For Comanche Peak, the pressurizer heaters used to satisfy the pressure control function are comprised of one proportional control group and three backup groups. The design and operation is consistent with the basis for an 18 month surveillance described in Section 6.Q of NUREG-1366 (which was the basis for TSTF-93). The heater groups are normally connected to the emergency power supplies (two to each Class 1E train of emergency power) and normally operate. CPSES will revise the 3.4.9 BASES to reflect the NUREG-1366 basis for the 18 month frequency.
FLOG RESPONSE (supplement): TSTF-93, Rev. 2, contains the following Reviewer's Note, "The frequency for performing Pressurizer heater capacity testing shall be either 18 months or 92 days, depending on whether or not the oplant has dedicated safety-related heaters. For dedicated safety-related heaters, which do not normally operate,92 days is applied. for non-dedicated safety-related heaters, which normally operate,18 months is applied." As used in this note, safety-related heaters means heaters which are powered from a class 1E electrical distribution bus. Normal operation includes operation during power operations, unit start-up and/or unit shutdown. Dedicated heaters are heaters whose only function is the mitigation of a design basis event. This is consistent with Generic Letter 93-05, "Line-item Technical Specifications improvements to Reduce Surveillance Requirements for Testing During Power Operation," which indicated that the capacity of pressurizer heaters should be tested once each refueling interval for those plants without dedicated safety-related heaters, in all cases where a FLOG plant has used the 18 month frequency in the ITS for performing pressurizer heater capacity testing, the requirements of the Reviewer's Note identified above have been met.

STS SR 3.6.1.1 ITS SR 3.6.1.1 and Associated Bases CTS 4.6.1.1.c/d and 3/4.6.1.2 require leak rate testing in accordance with the Containment Leakage Rate Testing Program which is based on the requirements of 10 CFR 50 Appendix J, Option B. STS SR 3.6.1.1 requires the visual examination and leakage rate testing be performed in accordance with 10 CFR 50 Appendix J as modified by approved exemptions. ITS SR 3.6.1.1 modifies STS SR 3.6.1.1 to conform to CTS 4.6.1.1.c/d and 3/4.6.1.2 as modified in the CTS markup. The STS is based on Appendix J, Option A while the CTS and ITS are based on Appendix J, Option B.
Changes to the STS with regards to Option A versus Option B are covered by a letter from Mr. Christopher 1. Grimes to Mr. David J. Modeen, NEl, dated 11/2/95 and TSTF-
- 52. While the ITS SR 3.6.1.1 differences from STS SR 3.6.1.1 are in conformance with the letter and TSTF 52 as modified by staff comments, the changes to the ITS Bases as well as ITS 3.6.2 and ITS 3.6.3 and their associated Bases are not in conformance. See Comment Number 3.6.3-28 for additional concems with regards to CTS 4.6.1.2.c and 4.6.1.2.d at Comanche Peak. Also see Comment Numbers 3.6.0-2,3.6.2-5, 3.6.3-27, 3.6.3.28 and 3.6.3-37.
Comment: Licensees should revise their submittals to conform to the 11/2/95 letter and TSTF-52 as modified by the staff. See Comment Numbers 3.6.0-2,3.6.2-5,3.6.3-27, 3.6.3.28, and 3.6.3-37.
FLOG RESPONSE: (original)The 11/2/95 letter from C. Grimes (NRC) to D. Modeen (NEI),
TSTF-52 proposed Revision 1 (which includes the changes proposed by the staff) were reviewed for incorporation into the ITS. Based on this review, the ITS Bases have been revised to incorporate proposed Revision 1 of TSTF-52. Revision 1 addresses the NRC comments on Revision 0 of this TSTF but has not been approved by the Tech Spec Task Force. The FLOG will continue to evaluate any NRC/ industry approved revisions to TSTF-52 and will incorporate applicable changes into the ITS submittal as appropriate.
FLOG RESPONSE: (Supplemental): As discussed at the meeting on October 13-14,1998 and in a conference call on November 19,1998, the NRC reviewer provided specific comments that have been incorporated into this supplemental response. The FLOG understands that with these changes the NRC staff approves incorporation of TSTF-52 into the iTS.
For CPSES, the incorporation of TSTF-52 negates changes made under licensee initiated change CP-3.6-005 and thus CP-3.6-005 is withdrawn.

BASES
- . BACKGROUND The containment consists of the concrete reactor building, its steel liner, and the penetrations through this structure. The ;
structure is designed to contain radioactive material that <
. may be released from the reactor __ core following adliEERb i Neice Besh-testsitardifsCcMaJntccidentammutt-f0BW h3y' ~i)6 Additionally, this structure provides shielding from the fission products that may be present in the containment atmosphere following accident conditions.
1 The containment is a reinforced concrete structure with a cylindrical wall, a flat foundation mat tirLtEa'reactoricavity; pit pgjection, and a shallow Msphetical dome roof. The inside surface of the containment is lined with a carbon steel liner to r ensure a high degree of leak tightness during operating and accident conditions. -

The concrete reactor building is required for structural integrity of the containment undervfsafgh']las79]Q:1de@ _ cp n =
QDBA conanlons. The steel liner and its penetra<;1ons 0 3.6.1 06 establish the leakage limiting boundary of the containment.
Maintaining the containment OPERABLE limits the leakage of fission product radioactivity from the containment to the ,
environment. SR 3.6.1.1 leakage rate requirements comply 0 3.6.1-06 with 10 CFR 50, Appendix E 0ptienZB (Ref. 1), as modified by approved exemptions.
The isolation devices for the penetrations in the containment boundary are a part of the containment leak tight barrier. To maintain this leak tight barrier:
- a. All penetrations required to be closed during accident conditions are either:
- 1. capable of being closed by an OPERABLE automatic containment isolation system, or (continued)

APPLICABLE The safety design basis for the containment is that the SAFETY ANALYSES containment must withstand the pressures and temperatures of the limiting DBA without exceeding the design leakage rate.
The DBAs that result in a challenge to containment OPERABILITY from high pressures and temperatures are a loss of coolant accident (LOCA), a steam line break and a rod ejection CP 3.6 06 accident (REA) (Ref. 2~hnd 23,). In addition, release of significant fission product radioactivity within containment can occur from a LOCA or REA.

- air locks. ,
The containment air locks satisfy Criterion 3 of of the NP,0 Policy ;
StatG~nt 10CFR5013_6ic)J2M19 LC0 Each containment air lock forms part of the containment pressure boundary. As part of the containment prejsgrelboundary, the air j lock safety function is related to control of the containment '
leakage rate resulting from a DBA. Thus, each air lock's -
structural integrity and leak tightness are essential to the successful mitigation of such an event.
Each air lock is required to be OPERABLE. For the air lock to be considered OPERABLE, the air lock interlock mechanism must be OPERABLE, the air lock must be in compliance with the Type B air lock leakage test, and both air lock doors must be OPERABLE. The interlock allows only one air lock door of an air lock to be opened at one time. This provision ensures that a gross breach of containment does not exist when containment is required to be OPERABLE. Closure of a single door in each air lock is sufficient to provide a leak tight barrier following postulated events. Nevertheless, both doors are kept closed when the air lock is not being used for normal entry into end g exit from containment.
APPLICABILITY In MODES 1, 2, 3. and 4, a DBA could cause a release of radioactive material to containment. In MODES 5 and 6, the probability and consequences of these events are reduced due to the pressure and temperature limitations of these MODES.
Therefore, the containment air locks are not required in MODE 5 to prevent leakage of radioactive material from containment. The requirements fct the containment air locks during MODE 6 are addressedinLC03.9.33,"ContainmentPenetrations."

The interval is modified in ITS SR 3.6.2.2 from 6 months to 24 months.
This modification is in accordance with TSTF-17; however, the Bases changes are not in accordance with TSTF-17.
Comment: Revise the ITS Bases to be in accordance with TSTF-17 or justify the deviations.
FLOG RESPONSE (original): The ITS Bases for SR 3.6.2.2 has been modified to conform to TSTF-17, Revision 1, and reads, "..used for entry and exit (procedures require strict adherence to single door opening), this test is only required to be performed every 24 months. The 24 month Frequency is based on the need to perform this surveillance under the conditions that apply during a plant outage and the potential for loss of containment OPERABILITY when the Surveillance is performed with the reactor at power. The 24 month Frequency for the interlock is justified based on generic operating experience. The Frequency is based on enginee5ng judgement and is considered adequate given that the interlock is not challenged during the use of the airlock."
FLOG RESPONSE (revised): The ITS 3.6.2 Bases have been revised for the associated surveillance requirements consistent with TSTF-17, Rev.1.

i SR 3.6.2.2 The air lock interlock is designed to prevent simultaneous opening of both doors in a single air lock. Since both the inner and outer doors of an air lock are designed to withstand the maximum expected ,
post accident containment pressure, closure of either door will 4
support containment OPERABILITY. Thus, the door interlock feature

Periodic testing of this interlock demonstrates that the interlock will function as designed and that simultaneous opening of the inner and outer doors will not inadvertently occur. Due to the ptrely

This specification is based on GDCs 55, 56, and 57 which addresa the proper isolation for each "line" that penetrates containment. It is recognized that multiple lines can share the same penetration.
Licensees have always been required to assure that proper protection is provided for each line or flow path that passes through containment even if multiple flow paths share the same penetration. In this specification, the term
" penetration" has always meant each flow path that penetrates containment. Adding the words " flow path" to the specification clarifies this meaning.

' M isolation valve." Valves credited as containment isolation valves which are power operated (i.e. can
- be remotely operated) that do not receive a containment isolation signal do not have an isolation time as assumed in the accident ,
- analyses since they require operator action. Therefore. deleting .j reference to power operated isolation valve time testing reduces 1 i- the potential for misinterpreting the requirements of this SR i j while maintaining the assumptions of the accident analysis. i
! 3.6 8 Revises the completion time for the restoration of containment i
!- pressure from I hour to [8] hours. The [8] hour completion time i
{ is consistent with the current TS. The [8] hours [is consistent

i REQUEST: DOC 7-08 M CTS 1.7.a CTS 3.6.1.7.b ,
CTS 3.6.1.7 ACTION b CTS 4.6.1.7.3 ;
STS SR 3.6.3.2 and Associated Bases ,
CPSES CTS 3.6.1.7.b requires the 18 inch containment pressure relief discharge isolation valves be OPERABLE. The CTS does not have a surveillance other than a leakage test (CTS ;
i 4.6.1.7.3) that verifies OPERABILITY of these valves. However, the wording of CTS 3.6.1.7 ACTION b and CTS 4.6.1.7.3 implies that these valves are normally closed, but can be opened ;
during operation for specific reasons. Thus, OPERABILITY would verify that the valves are closed. STS SR 3.6.3.2 is not used in the CPSES ITS. Based on CTS 1.7.a. CTS 3.6.1.7.b, ,
CTS 3.6.1.7 ACTION b, and CTS 4.6.1.7.3, the Staff believes that STS SR 3.6.3.2 is applicable j to CPSES ITS and that DOC 7-08 M should apply.
Comment: Revise the CTS /ITS markup to include STS SR 3.6.3.2 and associated .
Bases. Provide the appropriate discussion and justification for this More Restrictive change. , ;
FLOG response (original): The surveillance requirement STS SR 3.6.3.2 would require verification that the containment pressure relief valve is closed except when open for pressure l I
control, ALARA or air quality considerations for personnel entry or for surveillance that requires the valves to be open. This requirement is not contained in the CPSES CTS based on the following justification currently included in CPSES CTS Bases for 3/4.6.1.7 CONTAINMENT <
VENTILATION SYSTEM: l "The use of the Containment Ventilat'on System during operations is restricted to the 18-inch pressure relief discharge isolation valves (with an effective diameter of 3 inches) :
since, these venting valves are capable of closing during a LOCA or steam line break j accident. Therefore, the Exclusion Area dose guideline of 10CFR100 would not be exceeded in the event of an accident during containment venting operation."
The valves are designed and qualified to be open during MODES 1 through 4 in accordance !
with SRP 6.2.4 (Rev. 2, July 1981)" Containment Isolation System" and BTP CSB 6-4 (Rev. 2, July 1981)" Containment Purging During Normal Plant Operation." A debris screen covered by <
an orifice plate which restricts the effective opening to s 3 inches is provided to ensure the !
. valves can close in the event of a LOCA and the valves are designed to close within 5 seconds ,
I of a containment isolation signal. Hence, the current Licensing basis and the CTS do not require a containment pressure relief valve to be considered inoperable if open for any reason.
Therefore, STS SR 3.6.3.2 should not be considered applicable to CPSES and is not a condition for the containment isolation valves to be OPERABLE.

, FLOG response (supplement): The 18-inch pressure relief valve was discussed at the meeting on October 13-14,1998, at which time the NRC Containment Systems technical reviewers noted that several plants had been licensed with unrestricted usage of this valve. For CPSES, the NRC Staff concluded in Supplement No. 23 to NUREG-0797 (CPSES SER) that
- the design of the 18-inch pressure relief valve met the guidelines of BTP CSB 6-4 and that .
unrestricted usage of the valve was acceptable. l ATTACHED PAGES:

l CTS 3.6.1.1 ACTIONS CTS 4.6.1.1.a !
ITS 3.6.3 ACTIONS ITS SR 3.6.3.3, SR 3.6.3.4 and Associated Bases CTS 4.6.1.1.a verifies that all penetrations not capable of being closed by OPERABLE automatic isolation valves and required to be closed during accident conditions are closed by valves, blind fianges, or deactivated automatic valves secured in their positions. The corresponding ITS SRs for this CTS surveillance are ITS SR 3.6.3.3 for valves outside i containment and ITS SR 3.6.3.4 for valves inside containment. IF CTS 4.6.1.1.a cannot be met, the ACTIONS of CTS 3.6.1.1 are entered which require restoration of valve OPERABILITY within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> or shutdown within the following 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />. If ITS SR 3.6.3.3 or ITS SR 3.6.3.4 cannot be met, the ACTIONS of ITS 3.6.3 are entered which allows for one valve inoperable between 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> and 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> depending on the type of penetration to restore valve OPERABILITY before shutdown commences. This Less Restrictive change to the CTS ic not justified.
Comment: Revise the CTS markup to show this Less Restrictive change and provide the appropriate discussions and justifications.
FLOG RESPONSE (original): Diablo Canyon, Commanche Peak, Wolf Creek, and Callaway have evaluated this issue and have concluded that no change in requirements occurred, the content of CTS SR 4.6.1.1.a was moved to ITS SR 3.6.3.3 and ITS SR 3.6.3.4 with the required action time being moved to ITS LCO 3.6.3 ACTION B (see DOC 01-02-A).
l Additionally, some implicit valve OPERABILITY aspects of CTS SR 4.6.1.1.s were combined with CTS LCO 3.6.3 ACTION and are now shown as ITS LCO 3.6.3 ACTION A, B and C for l DCPP. CTS SR 4.6.1.1.a was written to provide assurance that"all penetrations not capable of being closed . . are secured." Containment OPERABILITY is associated with penetration flow paths per the CTS Bases 3/4.6.1.1 which states " CONTAINMENT INTEGRITY ensures that releases ... will be restricted to those leakage paths ... assumed in the safety analysis." The flow path (penetration) must be unsecured for the condition of CTS SR 4.6.1.1.a to not be met.
Under CTS LCO 3.6.3 - ACTION, one inoperable containment isolation valve (a valve unsecured /out of position for a penetration "not capable of b ing closed during an accident")
would provide 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> to restore the valve or secure the fu path. This was not changed under ITS 3.6.3 ACTION A. One " penetration" not meeting the cc >$ dons of CTS SR 4.6.1.1.a (two valves unsecured /out of position in the same flow path) wou.d provide one hour to secure one valve closed in order to restore containment OPERABILITY. This was also retained under ITS 3.6.3 ACTIONS B.
DOC 01-02-A will be revised to read " Conditions A, B, and C and Surveillance Requirements (SR) 3.6.3.3 and SR 3.6.3.4."
FLOG RESPONSE (supplement): The original response provided for this comment continues to reflect the position of the FLOG members and is the understanding being used in the e implementation of these specifications. The changes are still considered to be administrative.
After discussion with the NRC staff and to facilitate the conversion review, an LS DOC and its associated NSHC are being provided.

-f-1 03 A The action statements are revised to incorporate the NUREG 1431 equal alternative isolation method of a " check valve with the flow through the valve secured." This isolation method is provided in NUREG 1431 and is cor.sidered an acceptable variation of a de-activated automatic valve.
1 04 LS-1 A note is added to valve and blind flange survcillance requirements consistent with NUREG 1431. The note allows verification of valves, flanges and isolation devices located in high radiation areas to be verified by use of administrative means. This change is less restrictive in that the current TS SR 4.6.1.1 has an exception to valves, blind flanges, and deactivated automatic valves which are located inside containment and are locked, sealed, or otherwise secured in the closed position. These valves shall be verified closed during each' COLD SHUTDOWN.
However, under the current TS, if an area outside of ,
containment became a high radiation area, entry into the I area would still be required to verify the closed positions. The ITS would allow verification of all areas ;1 e that are high radiation areas or become high radiation i areas by administrative means once they had been verified !

! CTS 4.6.1.2.c CTS 4.6.1.2.d STS SR 3.6.1.3.11 and Associated Bases (NUREG 1434) l STS SR 3.6.1.3.14 and Associated Bases (NUREG 1433)
E ITS B3.6.1 Bases - SR 3.6.1.1 i
CPSES CTS 4.6.1.2.c requires a leak test with gas at not less than P, or a hydrostatic f test at not less than 1.1P, for certain Safety injection valves. CPSES CTS 4.6.1.2.d requires a hydrostatic test at not less than 1.1P, for certain containment spray valves.
Amendment 51 for Unit 1 and Amendment 37 for Unit 2 converts the CTS from 10 CFR 50 Appendix J Option A to 10 CFR 50 Appendix J Option B. CTS 4.6.1.2.c and l
4.6.1.2.d were retained during that conversion. The CTS markup shows these j surveillances ,as being relocated to the Containment Leakage Rate Testing Program and
- ' the Bases for ITS SR 3.6.1.1. DOC 2-05 LG justifies the relocation based on the level of detail in the TS not being consistent with NUREG-1431. Consistency with NUREG-1431 is not an acceptable justification for relocating material from the CTS to a licensee j
controlled document. In the development of NUREG-1431 a specific SR with regards to I hydrostatically testing containment isolation valves for leakage was not included because the WOG stated that most units did not have any valves that were hydrostatically tested. This was not the case for the BWRs (NUREGs 1433 and 1434) which had hydrostatically tested valves. In that case, STS SR 3.6.1.3.11 (NUREG-1434) and STS SR 3.6.1.3.14 (NUREG-1433) were included in the NUREGs. Changes to the STS with regards to Option A versus Option B are covered by a letter from Mr.
Christopher I. Grimes to Mr. David J. Modeen, NEl dated 11/2/95 and TSTF-52 as modified by the staff. Neither document deleted or relocated those BWR SRs, but retained the SRs in a modified form. In addition, the SE associated with Amendments 51 and 31 states that the changes are in accordance with the 11/2/95 staff letter. Thus, the Staff requires that CTS 4.6.1.2.c and 4.6.1.2.d be retained.
Comment: Revise the CTS /ITS markups to show CTS 4.6.1.2.c and 4.6.1.2.d as being
- retained as SRs in ITS 3.6.3. Provide additional discussions and justifications as necessary for this change.
FLOG response: (original) Current CPSES surveillance requirements CTS 4.6.1.2.c and 4.6.1.2.d are retained and have been added to the markup of ITS 3.6.3," Containment isolation
' Valve," as new surveillance requirements SR 3.6.3.12 and SR 3.6.3.13, respechvely. CTS Bases information supporting these surveillances has similarly been retained by adding it to the ITS Bases for SR 3.6.3.12 and SR 3.6.3.13.
.. Further, DOC 2-05 A has been revised to read; "CPSES surveillance requirement CTS 4.6.1.2.c for leak testing of specified safety inje: tion valves is renumbered and retained as new ITS SR 3.6.3.12. This change would not change the existing requirement but simply renumbers and
"CPSES surveillance requirement CTS 4.6.1.2.c for leak testing of specified safety injection valves is renumbered and retained as new ITS SR 3.6.3.12. This change would not change the existing requirement but simply renumbers and !
modifies the format to be consistent with the ITS. This change would be I classified as Administrative (A)." ;
Also, DOC 2-07 A has been added to read; "CPSES surveillance requirement CTS 4.6.1.2.d for leak testing of specified containment spray valves is renumbered and retained as new ITS SR 3.6.3.13.
This change would not change the existing requirement but simply renumbers and modifies the format to be consistent with the ITS. This change would be ,
classified as Administrative (A)." ;
Also, see the FLOG responses to Comments 3.6.1-1 and 3.6.3-2 regarding the .
relocation of the CONTAINMENT INTEGRITY definition requirements.
- FLOG RESPONSE: (supplement) SR 3.6.3-12 and SR 3.6.3-13 have been revised to add the words "to be within limits" in reference to the surveillance leakage limits which are specified in the Bases. The revision makes the surveillance wording consistent with standard STS surveillance terminology.
Also, JFD 3.6-24 has been revised to be JFD 3.6-25 since JFD 3.6-24 had previously been used by another FLOG member for a separate change. .

REQUEST: STS B3.6.7 Bases - BACKGROUND j ITS B3.6.7 Bases - BACKGROUND
. l The last paragraph in STS B3.6.7 Bases - BACKGROUND has been deleted from i CPSES ITS B3.6.7 Bases - BACKGROUND. Since ITS changes to the STS Bases l were made based on changes to the STS on plant specific system design, or on current licencing basis as specified in the CTS, the deletion does not seem to fall into any of these categories. The paragraph provides a description of how the Spray Additive System operates when activated, and is applicable to CPSES.
Comment: Revise the ITS markup to include this paragraph modified to specify plant ;
specific parameters or provide a discussion and justification for its deletion based on system design, operational constraints or current licensing basis.
FLOG response: (original) The change to the B3.6.7 Bases - BACKGROUND is based on plant specific system design and licensing basis. However, a plant specific description of the eductor design is provided in place of the deleted sentence to provide comparable details for CPSES.The spray additive system, including the eductors, is designed to ensure the contents of the Chemical Additive Tank is injected into containment given any single active failure.
Consequently, in the short term, the pH of a train of spray can vary from acidic to strong basic.
The low spray pH can only occur during injection prior to switchover to recirculation. The equilibrium sump solution pH is alsove 7 and adequate spray pH for long term iodine retention is achieved with the onset of the spray recirculation mode. The high spray pH can only occur after switchover to recirculation from the sump when spray additive is added to recirculated sump water. The high pH condiNo transient is bounded by the hydrogen generation analysis.
FLOG RESPONSE:(revised) The Background discussion of the Spray Additive System has been revised to restore the deleted paragraph as modified to be specific to CPSES.

ADDITIONAL INFORMATION COVER SHEET ADDITIONAL INFORMATION NO: Q3.6.7-16 APPLICABILITY: CP REQUEST: ITS B3.6.7 Bases- SR 3.6.7.5 CPSES ITS B3.6.7 Bases SR 3.6.7.5 adds the following sentences: " Flow of between 50 and 100 gpm through the eductor test loops (supplied from the RWST) simulates flow from the Chemical Additive Tank. The flow rate through the eductors is not critical because the entire Chemical Additive Tank contents is injected prior to isolation." The latter sentence is confusing. In one sense it implies that the SR is not needed tiow rate...not critical." In another sense it implies that even if the flow rate is substantially less than 50 gpm, the contents of the tank will be injected before the system isoiates.
See Comment Number 3.6.7-17 for a related concem.
Comment: Provide a discussion and justification for this change based on system design, operation constraints or current licensing basis. See Comment Number 3.6.7-17.
FLOG response: (original) The CTS require that RWST test water flow rates of between 50 gpm and 100 gpm through the eductor test loop of each train of the spray additive system be varified at least once per 5 years. The CTS BASES only describe the long term pH requirements for the spray additive system. The specified flow rates of 50 and 100 gpm are arbitrary and were not used in any safety analysis. The long term sump pH is not affected by the specific eductor flow rates since the design ensures the entire contents of the Chemical Additive Tank (CAT) are injected prior to isolation. Only short term spray pH is affected by the eductor flow rates. As described in the response to 3.6.7-12, above, the short term pH range is not significant. In fact, lower eductor flow rates are better for the short term since that would minimize the maximum spray pH. High eductor flow rates from the CAT were established by pre-operational testing and used for the bounding pH transient analyses. Flow testing through the RWST test loop is neither precise nor required to verify critical parameters. This surveillance is only required to ensure the eductors are not blocked and are capable of educting. The ITS BASES do not require additional changes.

APPLICABLE The safety design basis for the containment is that the SAFETY ANALYSES containment must withstand the pressures and temperatures of the.
limiting DBA without exceeding the design leakage rate.
The DBAs that rewit in a challenge to containment OPEPABILITY from high pressures and temperatures are a loss of coolant -
accident (LOCA), a steam line break and a rod ejection m3.646 accident (REA) (Ref la 23). In addition, releax J significant fission uct radioactivity within containment can occur from a LOCA or REA. In the DBA analyses, it is assumed that the containment is OPERABLE such that, for these DBAs involving release of fission product radioactivity, release to the environment is controlled by the rate of containment leakage. The containment was designed with an allowable leaka of 3.6.0-02
@JM of containment air weight per day (Ref. 32 .
This leakage rate, used to evaluate offsite doses resulting CP 3.6 06 from accidents, is defined in 10 CFR 50, Appendix J2 Optjojr 0 3.6.1 06 R](Ref.1),asL,: the maximum allowable containment leakage rate at the calculated peak containment internal pressure (P ) resulting from the limiting DBA.
