qy@nW ~69 ITS SECTION 5.2 ORGANIZATION Description ofIssue 5.2-1 NRC Comments TVAResponse The term "health physics" in CTS 6.2.1d and 6.2.2e is changed to "radiological controls" in ITS 5.2.1d and 5.2.2d with no justification for the change from the CTS "health physics." The term "health physics" in STS 5.2.1d and 5.2.2d is changed to "radiological controls" in ITS 5.2.1d and 5.2.2d. JD P3 states that this is because it is the current licensing basis, but CTS 6.2.1d and 6.2.2e use the term "health h sics." The material is contradicto Provide further justification for using the term "radiological controls" instead of"health h sics."
TVAhas substituted the term radiological controls in Improved Technical Specifications ITS) for the term "health physics" used in the STS because the associated function and organization is known at Browns Ferry as radiological controls. This change is consistent with the Tennessee Valley AuthorityTopical Report, TVA-NPOD89-A, Nuclear Power Organization Description, referenced in UFSAR section 13.2.4 for the onsite or anization.
Description of Issue 5.2-2 NRC Comments TVAResponse The bracketed STS 5.2.2a requirements for the number ofnon-licensed operators at a two-unit station when both units are shutdown is deleted in the conversion to ITS 5.2.2a with no discussion ofits a
licabilit to the Browns Fe
's three-unit site.
Provide a discussion ofthe applicability ofthe STS bracketed information for BFN.
AAer further review, TVAhas incorporated the bracketed requirements, modifying it slightly to reflect the fact that Browns Ferry has three units. The proposed change is less restrictive than CTS Table 6.2.A. A new DOC L1 has been added to address this chan e.
Description of Issue 5.2-3 NRC Comments TVAResponse CTS 6.2.2d requires two licensed reactor operators (RO) and a licensed senior reactor operator (SRO) in the control room when in MODE 1, 2, or 3. ITS 5.2.2b requires at least one RO and one SRO in the control room when in MODE 1, 2, or 3. Deleting the second re uired RO is not ustified and is a less restrictive chan e.
Provide discussion and 'ustification for this less restrictive chan e
TVAagrees with the comment. Ajustification for this less restrictive re uirement OC L2 has been added.
ITS SECTION 5.2 ORGANIZATION Description of Issue 5.2-4 NRC Comments TVAResponse I
CTS Table 6.2.A Note b allows a shift crew composition ofone less than specified for a time not to exceed two hours. ITS 5.2.2c does not limitthe short complement to one, a less restrictive change.
Though consistent with the STS, this less restrictive change has not been 'ustified.
Provide discussion and 'ustification for this less restrictive chan e.
TVAagrees with this comment. Ajustification for this less restrictive re uirement OC L3 has been added.
Description ofIssue 5.2-5 NRC Comments TVAResponse CTS Table 6.2.A Note b does not permit any shift crew position to be unmanned upon shiR change due to an oncoming shift crewman being late or absent.
ITS 5.2 does not retain this requirement, a less restrictive removal ofrequirements that is not specifically discussed or 'ustified in LAl.
Provide discussion and justification.for this less restrictive removal of re uirement.
A specific less restrictive requirement (DOC L4)justification has been added to address this comment.
ITS SECTION 5.4 PROCEDURES Description ofIssue 5.4-1 NRC Comments TVAResponse CTS 6.8.2 requires annual drills for a) emergency conditions involving release ofradioactivity and b) failures ofsafety-related systems or components.
The justification states these requirements are im lemented b the Radiolo ical Emer enc Plan.
Does the Radiological Emergency Plan implement an annual drillfor failures ofsafety-related systems or components?
Provide additional justification for this less restrictive removal ofrequirements, verifying where the requirement for an annual drillfor failures ofsafety-related s stems or corn onents willbeim lemented.
DOC LA2 has been revised to provide additional justification to address the issues in this NRC comment.

Description of Issue 5.5-2 NRC Comments TVAResponse CTS 4.7.B.1 requires demonstrating acceptable pressure drop for the combined HEPA filters and charcoal adsorber banks ofthe standby gas treatment system and testing the inlet heaters "at least once per year." ITS 5.5.7 establishes the required testing "at least once per 18 months." This extension ofthe surveillance test interval is not
'ustified as a less restrictive chan e.
Provide ustification for this less restrictive chan e.
Ajustification for this less restrictive change has been included (DOC L3 Description of Issue 5.5-3 NRC Comments TVAResponse CTS 4.7.B.1c requires demonstrating the air distribution across the standby gas treatment system HEPA filters and charcoal adsorbers is uniform within 20%. This requirement is not transferred to ITS 5.5.7 but is moved to the Technical Requirements Manual. No justification was provided for this change in DOC LAl. DOC LA1 simply rovides a ve briefdescri tion ofsome ofthe chan es it covers.
Provide a justification specific to this less restrictive moving ofa re uirement.
The requirement contained in CTS 4.7.B.1c willbe deleted. A
'ustification for this deletion has been included DOC L2 Description of Issue 5.5-4 NRC Comments TVAResponse CTS 3.8.A.6 requires suspending additions ofradioactive waste ifthe specified limits are exceeded, reducing the activity in the tank to within limit, and reporting the occurrence in the next annual Radioactive Efnuents Release Report.
These requirements are not transferred to ITS 5.5.8 but are moved to the Technical Requirements Manual. No justification was provided for this change in DOC LA1. DOC LA1 simply provides a very briefdescription of some ofthe chan es it covers.
Provide a justification specific to this less restrictive moving of a re uirement.
The previously submitted justification (DOC 5.5 LA1) has been revised to rovide additional detail.
ITS SECTION 5.5 PROGRAMS AND MANUALS Description of Issue 5.5-5 NRC Comments TVAResponse CTS 4.8.A.6 requires analyzing samples ofthe contents ofany outside liquid radwaste storage tanks at least once per 7 days when there are additions to the tank. These specific requirements are not transferred to ITS 5.5.8. Rather, ITS 5.5.8 contains general requirements for a surveillance program for verifying the quantity of radioactivity contained in outdoor liquid radwaste tanks.
Deleting the s ecific re uirements in CTS 4.8.A.6 was not 'ustified.
Provide a 'ustification for deletin this re uirement The specific requirements contained in CTS 4.8.A.6 willbe relocated to the Technical Requirements Manual (TRM). The previously submitted justification (DOC LA1) has been revised to reflect this relocation.
Description of Issue 5.5-6 NRC Comments TVAResponse STS 5.5.10a requires testing new diesel fuel oil before adding it to storage tanks. ITS 5.5.9 does not contain this requirement although the justification in P 1 1 states that the fuel oil is tested before adding it to the 7 da tanks.
For standardization and consistency, the staF would prefer to see the STS requirements retained in the Browns Ferry ITS. What is the impediment to including these requirements in the ITS, ifthe testing is alread bein done?
Adoption ofthe STS provisions would result in a considerable increase in testing requirements for diesel fuel oil, which based on plant experience with existing TS requirements and testing, would not produce a significant increase in assurance offuel oil quality.
Further detail is provided below.
CTS 4.9.A.l.e requires a quarterly test ofthe fuel oil for the emergency diesel generator 7-day tanks to verify compliance with ASTM-D-975-1989. BFN has eight EDGs each ofwhich has a 7-day tank. Each EDG directly draws fuel from a day tank which is integral with the EDG skid. When the oil level in any ofthe day tanks falls below a predetermined setpoint, oil is automatically transferred from the associated 7-day tank to the appropriate day tank. When the level in the 7-day tank falls below a predetermined limit, oil is manually transferred from Fuel Oil Storage Tank ¹2 to the appropriate 7-day tank. As noted in Pl 1, the oil in Fuel Oil Storage Tank ¹2 is verified to meet ASTM-D-975-1989 prior to storage in the tank. Hence, the make-up source for the 7-day tanks is tested for ualit
ITS SECTION 5.5 PROGRAMS ANDMAIAJALS TVAResponse 5.5-6 continued STS 5.5.10 would require that a reduced scope test ofthe 7-day tank fuel oil be performed on a monthly basis.
Therefore, STS provisions, ifimplemented, would significantly increase the oil testing requirements over the quarterly testing required by CTS.
Operating experieace with the CTS quarterly sampling ofeach ofthe 7-day tanks as augmented by the testing ofthe 82 oil tank indicates that the current oil testing program maintains acceptable fuel quality for the EDGs. More fi'equent testing in accordance with STS provisions would require a considerable increase in resources with no obvious expected improvement in terms ofincreased assuraace ofoil quality. Based on these consideratioas, BFN considers that retention ofthe CTS fuel oil testing requirements as proposed in the ITS is a
ro riate.
Description of Issue 5.5-7 NRC Comments TVAResponse STS 5.5.4.b has been modified in ITS 5.5.4.b to adopt the CTS which includes changes to conform to the latest 10 CFR Part 20 revision. However, it appears that the transfer ofthe CTS language was not entirely accurate.
CTS 6.8.4.b states, "Limitations oa the concentrations ofradioactive material released in liquid efHuents to UNI&STRICTEDAREAS conforming to 10 times the concentration values stated in 1D CFR 20.10001-20.2401, Appendix B, Table 2, Column 2." ITS 5.5.4.b states, "Limitations on the concentrations ofradioactive material released in liquid eQluents to unrestricted areas, conforming to 10 times the concentration values stated in 10 CFR 20, A endix B Table 2, Column 2."
Revise the ITS to retain the correct CTS reference for 10 CFR Part 20.
The existing reference to 10 CFR 20 in CTS 6.8.4.b was based on a previous version of 10 CFR 20. The revised reference contained in the submittal is correct for the current version of 10 CFR 20.
Therefore, the ITS should aot be changed Rom the original submittal.
DOC A10 has been added to cl this oint.
ITS SECTION 5.5 PROGRAMS AND MANUALS Description of Issue 5.5-8 NRC Comments TVAResponse ITS 5.5.7 adds Insert 5.0-11A to the program description ofSTS 5.5.8 for the VFTP. Most ofthe additional information in the insert is based on CTS. However, the addition ofthe reference to Section Sa ofRe lato Guide 1.52, Rev. 2, is not discussed.
What is the reason for adding the reference to Section 5a, rather than leavin the eneral reference as in the STS?
Current licensing basis does not commit Browns Ferry to meet the requirements ofRegulatory Guide 1.52. Therefore, all references to Regulatory Guide 1.52 have been removed &om ITS and ITS has been revised to be more consistent with CTS requirements in this area.
Refer to the revised ITS pages and accompanying justifications for more detail.
Description of Issue 5.5-9 NRC Comments TVAResponse ITS 5.5.7.c requires demonstrating that a laboratory test ofa sample ofcharcoal adsorber shows the methyl iodide penetration less than the specified value, at a specified flowrate and relative humidity.
The CTS do not appear to contain the restrictions on relative humidi, but no discussion ofthis chan e was rovided.
Provide a justification ofthis change, stating how the value in the ITS was derived.
ARer further review, Browns Ferry has decided to reinstate CTS requirements.
Therefore, ITS 5.5.7.c has been revised to delete the specification on relative humidity. It simply requires the sample to be tested in accordance with ASTM D3803-19&9.
Description ofIssue 5.5-10 NRC Comments STS 5.5.2a and b requires a Primary Coolant Sources Outside Containment program with preventive maintenance and leak test requirements.
ITS 5.5.2 implements this program, however, ITS, 5.5.2a does not contain the preventive maintenance requirements and ITS 5.5.2b adds a restriction on the leak rate testing "to the extent permitted by system design and radiological conditions." The justi6cation states that these changes are consistent withBFN's current ro amsforminimizin leaka e.
Provide additional justi6cation for this STS deviation based on system design and operational constraints.
What are your current commitments to the NRC regarding primary coolant sources outside containment?
ITS SECTION 5.5 PROGRAMS AND MANUALS TVAResponse 5.5-10 continued Browns Ferry's current commitment for controlling leakage of systems which may contain highly radioactive fluids during a serious transient or accident is contained in UFSAR, Section 6.6, and states, "The CSCS (Core Standby Cooling Systems) piping and components in the Reactor Building are monitored by routine inspections, general housekeeping practices, and system operability testing which maintains system leakage to an as-low-as-possible level. Browns Ferry does not have a specific commitment to have a separate preventive maintenance program for leak reduction, but rather uses the normal program for the ECCS and the leak reduction strategy discussed above.
Therefore, the ITS as proposed deviates from the STS to remain consistent with our current methods and commitments.
Additionally, section 5.5.2.b is modified to indicate that system leak rate tests are conducted to the extent permitted by system design and radiological conditions.
Since Browns Ferry CTS do not have equivalent provisions for a leak reduction program, we believe that the ITS should be made more specific in this regard to ensure effective im lementation.
ITS SECTION 5.6 REPORTING REQUIREMENTS Description of Issue 5.6-1 NRC Comments TVAResponse CTS 6.9.1.2.b requires annual reporting to the NRC ofany main steam reliefvalve that opens in response to reaching its setpoint or due to operator action to control reactor pressure.
The justification neither details why this requirement is in the CTS, states whether this requirement is moved elsewhere (and the attendant controls on the requirement where moved), nor states that the requirement is being deleted entirel Provide additional justification for this less restrictive removal of requirements, stating what willhappen to the requirement when the ITS are im lemented.
AAer further review, we have determined that the specific requirements ofCTS 6.9.1.2.b can be deleted. Ajustification (DOC L2 has been added.
Description ofIssue 5.6-2 NRC Comments TVAResponse LA3 states that the source test reporting requirements ofCTS 6.9.1.6 are being moved to an unidentified licensee controlled document.
No ustification is bein rovided for this chan e.
Provide a justification for this less restrictive moving ofrequirements, identifying the document that willcontain this requirement and the corres ondin control mechanism.
The requirements contained in CTS 6.9.1.6 willbe relocated to the TRM. The previously submitted justification (DOC LA3) has been revised to reflect this relocation.
Changes to the TRM are controlled in accordance with 10 CFR 50.59.
Description ofIssue 5.6-3 NRC Comments TVAResponse The criteria in the NRC Final Policy Statement and 10 CFR 50.36 do not apply to the Administrative Controls section oftechnical s ecifications. The criteria onl a
1 to LCOs.
Revise the justifications for these items to describe less restrictive changes (movement ofrequirements).
Identify, specifically, the documents to which these requirements willbe moved and the associated control mechanisms.
Justifications (DOC R1-R4) have been revised to address the NRC comment.
ITS SECTION 5.7 HIGH RADIATIONAREA Description ofIssue 5.7-1 NRC Comments TVAResponse CTS 6.8.3.2 provides requirements for "areas that are accessible to personnel and that have radiation levels greater than 1 rem in 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />." ITS 5.7.2 references "areas that are accessible to personnel and that have radiation levels ~ 1000 mrem/hr."
Revise ITS 5.7.2 to change "> 1000 mrem/hr" to "> 1000 mrem/hr" to be consistent with CTS.
TVAagrees with the NRC comment and has revised ITS 5.7.2 as described in NRC comment 5.7-1 to be consistent with CTS.
