t December 1998

an REQUEST FOR ADDITIONAL INFORMATION REGARDING CONVERSION TO IMPROVED STANDARD TECHNICAL SPECIFICATIONS, SECTION 3.3 FOR FERMI 2 (TAC NO. MA1465)

General Ncig:

1. Throughout this request for additional information (RAI), references to a standard technical specification (STS) maan the standard version of the TS published by the NRC in NUREG-1433, " Standard Technical Specifications, General Electric Plants, BWR/4,"

Revision 1. References to an improved TS (ITS) mean the proposed converted TS submitted by the licensee.

2. For the more complex issues that were resolved after the December 1 through December 3 meeting, Enclosure 2 provides a discussion of the resolution.

General Comments 3.3-1 Generic LX-DOC 3.3.2.1: LA.2, LA.3, LB.1, LC.1; 3.3.3.1: LR.1, LR.2; Comment: Clarify that the proposed current technical specification (CTS) limits described in these Discussions of Change (DOCS) can be changed without affecting safe operation of the plant. These L-DOC discussions do not provide sufficient supporting evaluation ( e.g., contains unsubstantiated conclusions, vague statements i.e., "This change is acceptable because the Operability for .. . is unchanged") for the staff to conclude that the proposed less restrictive generic changes do not present a significant safety question in the ooeration of the plant and that the TS requirements that remain are consistent with current licensing practices, operating experience and plant accident and transient analyses. Note that the CTS requirements associated with DOC LB.1 were deleted by Amendment No.122 dated July 13,1998.

Revirion 2 to the conversion submittal will reflect the changes acsociated with the amendment and the staff will review the revision. Therefore, this portion of this question is resolved.

Detroit Edison Response:

J 3.3-2 Generic LA.1 DOC ITS: 3.3.1.1; 3.3.2.1; 3.3.2.2; 3.3.4.1; 3.3.5.1; 3.3.5.2;3.3.6.1; 3.3.6.2; 3.3.6.3 (LA.2); 3.3.7.1; 3.3.8.1 Comment: The CTS proposes to move trip set point LCO requirements to the TRM. DOC LA.1 does not adequately discuss the CTS trip set point changes. Provide a revised DOC that eveluates the CTS requirements as operational limits and the CTS Allowable Values as TS l operability limits. Explain how the ITS preserves the relationship between these limits and why it is sufficient to rely on the Allowable Values in determining trip channel operability for RPS instrumentation.

Detroit Edison Response:

E3 Global R DOC Comment: R DOCS provide discussion and justification for relocating CTS requirements. The Selection Criteria is correctly applied to these relocated requirements. The Summary ENCLOSURE 1

a s Disposition Matrix in the conversion submittal provides the name of the licensee document to which the CTS requirements are relocated but does not identify the regulation that will control future changes to the relocated requirements. Provide this information.

Detroit Edison Response:

3.3- 4 Generic A-DOC l A.10: 3.3.1.1 A.3: 3.3.2.1, 3.3.4.1, 3.3.5.1, 3.3.5.2, 3.3.6.1, 3.3.6.2, 3.3.7.1, 3.3.8.1 Comment: CTS specified Actions for set points not within limits are eliminated as an administrative presentation preference only. These Actions state " declare the channel inoperable until the channel is restored to Operable status." ITS contain all the requirements and Actions for channels, including the set points and the usage rules of TS adequately dictate that channels be declared inoperable. Revise these A-DOCS to clarify which limits and set ,

points are affected by the changes. I Detroit Edison Response:

3.3 5 Generic A-DOC A.11: 3.3.1.1 A.4: 3.3.5.1, 3.3.5.2, 3.3.8.1 A.5: 3.3.4.1, 3.3.6.1, 3.3.6.2 Comment: The CTS requirement to perform a " simulated automatic operation" of all channels is deleted in the ITS. The DOCS indicate this is acceptable because the deleted requirement is synonymous with the logic system functional test (LSFT) and/or channel functional test (CF7).

Revise the DOC to explain how this justification relates to ITS requirements.

3.3.1.1- 2 DOC A.3 CTS 3.3.1, Actions a.2and a.3, and footnotes

  • and "

Comment: This DOC equates TS Action requirements with " directions on options for compliance" and states that " detailed direction for these options" are not included in ITS 3.3.1.1; rather " optional Actions presented rely upon the guidance of LCO 3.0.2." Comment: This DOC provides an obscure discussion for an administrativo change. It relates CTS requirements, taken out of context, to undocumented interpretations of !TS Section 3.0 generic requirements.

i. Comment: LA.3 states: " CTS 3.3.1, Action a.1 addresses the necessary requirements for a loss

! of RPS scram capability (one trip system with more than one inoperable channel in any I l Functional Unit." ITS Condition C includes loss of trip capability in either one or both trip

! systems. The CTS uses two Actions (a.1 and b) to address the same set of inoperable conditions. Revise DOC LA.3 discussion to address loss of RPS functional capability changes included in all CTS Actions.

Detroit Edison Response:

l 3.3.1.1- 9 DOC LA.5 l

Comment: What is the safety basis justification for not requiring that the shorting links be removed if the shutdown margin requirements in TS are not met. What is the safety basi',

justification for not increasing the required number of operable average power range mon.? ors (APRMs) to 4 per trip system from three per trip system and the number of operable intermediate range monitors (IRMs) to 6 per trip system from three per trip system if the shorting links are removed in Mode 5. This LA DOC needs to be restructured to specifically address the 3-f

's

't safety basis for the change. A statement of the safety function of the shorting links is missing from the narrative. The focus of the DOC should prove that the TS requirements that remain in the proposed ITS are sufficient to ensure safe operation of the plant. The conclusion states that

" relocation of shorting link removal requirements continues to provide adequate protection of the public....." Explain how " removed requirements" are able to continue to provide adequate protection of the public.

Detroit Edison Response:

Detroit Edison Response: l 3.3.1.1- 11 CTS 4.3.1.3 DOC LA.10 ITS SR 3.3.1.1.17 Comment: CTS 4.3.1.3 requires "each" reactor trip functional unit demonstrated within its Response Time limit (except Reactor Vessel Steam Dome Pressure - High and Reactor Vessel Low Water Level). Corresponding ITS SR 3.3.1.1.17 is required for all RPS functions except .

. IRMs, APRM Neutron Flux - High Setdown, APRM-Inoperable, Drywell Pressure - High, Main l Steam Line Radiation-High, Scram Discharge Volume Water Level- High, Reactor Mode Switch

- Shutdown Position, and Manual Scram. LA.10 specifies relocating RPS Response Time  !

testing requirements to plant procedures for those RPS trip Functions that have no specific acceptance criteria located in the Technical Requirements Manual (TRM). This DOC does not adequately justify the relocation of CTS requirements. It is not clear that testing requirements moved to plant procedures are not associated with Updated Final Safety Analysis Report (UFSAR) requirements, such as TRM requirements. The moved RPS testing requirements should be discussed separately, providing a technical basis for removal of each testing requirement from the ITS. Revise LA.10. See also RAls 3.3.6.1-6 and 3.3.6.2-3. Combine the responses to these three RAls if that appears appropriate.

3.3.1.1 13 CTS Actions (a) and (b)

DOC LC.1 Comment: The first part of the original question was resolved during the December 1 through December 3 meeting. The second part of the question remains: The first bullet in this DOC should be revised to state that CTS Action a.1 is for "one or more" channels inoperable. The second bullet in this DOC should '1ote that the ITS allows a 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> repair allowed outage time (AOT) for "any" inoperable channel.

3.3.1.1-16 CTS Action 7 DOC L.3 Comment: This DOC states that the associated actions for the Mode Switch in Shutdown are deleted consistent with NUREG-1433. NUREG-1433 requires Reactor Mode Switch - Shutdown Position to be operable (LCO 3.3.2.1) when the mode switch is in the shutdown position. CTS Action 7 requires verification that insertable control rods are inserted. Action 7 becomes LCO 3.3.2.1, Required Action E.2 in the ISTS. Revise L.3 to be consistent with NUREG requirements.

Justification For Difference (JFD) P.5 l

l Comment: The CTS require the licensee to verify overlap between the source range monitor l (SRM) and IRM channels during reactor startups. The STS SR 3.3.1.1.6 requires this overlap

! testing with the frequency stated as " Prior to withdrawing SRMs from the fully inserted position."

The frequency in ITS SR 3.3.1.1.6 is revised to read " Prior to fully withdrawing the SRMs from the core." The licensee considers this interpretation to be consistent with the CTS. However, all of the recent BWRs have adopted the STS version of the SR. There are no plant-specific l reasons cited by the licensee for this deviation from the STS. The licensee should adopt the l STS or provide plant-specific reasons for the deviation from the STS. l Detroit Edison Response:

The corresponding ITS 3.3.2.1 Applicability for the Rod Block Monitor is " THERMAL POWER greater than or equal to 30%". Adopting the STS would have resulted in an applicability statement that read " THERMAL POWER greater than or equal to 30% RTP". This difference in Applicability is not discussed orjustified.

The corresponding STS 3.3.2.1, Required Action C.2.1.2, also uses "per calender year" for this presentation. ITS 3.3.2.1 Required Action C.2.1.2 changes this presentation to "in the previous

l 12 months". DOC A.4 discussed this change as being an editorial wording preference. This change is considered unnecessary but requires a generic change before implementation.

, DOC L.3, P.5 l Comment: CTS require compliance with the " prescribed control rod pattem" by a second i licensed operator or other technically qualified number of the unit technical staff when the Rod l Worth Minimizer is inoperable. CTS surveillance 4.1.4.1.d establishes the prescribed control rod l pattom as the " Banked Position Withdrawal sequence," also referred to as the BPWS. Fermi l ITS, however, propose to deviate from the STS BPWS actions. The licensee proposed similar changes in ITS 3.1.3, 3.1.6, and 3.10.8. In RAI 3.1.3 (see the October 26,1998, RAI) the staff requested the licensee to revise the Bases for ITS 3.1.3 and 3.10.8 to more clearly define what is meant by " prescribed withdrawal sequence." Similar action should be taken for the ITS 3.3.2.1 Bases.

Detroit Edison Response:

l 3.3.2.1-4 CTS 3.3.1, Action 7; Table 3.3.6-1, Action 63 DOC A.1, JFD P.1 l

Comment: The ITS justifications state that the actions for the Control Rod Block Instrumentation Mode Switch in Shutdown position are consistent with CTS. In adopting CTS, ITS deletes LCO 3.3.2.1 Action E.1 (Suspend control rod withdrawal) and E.2 (Initiate action to fully insert all

, insertable control rods in core cells containing one or more fuel assemblies) and replaces these l I

actions with proposed Action E.1, " Initiate action to insert a control rod block." ITS Action E.1 is j not acceptable as a plant specific replacement for NUREG-1433 Action E.1. However, CTS Table 3.3.1-1 (Reactor Mode Switch-Shutdown Position) Action 7 requirements are consistent ,

with NUREG-1433 LCO 3.3.2.1 Condition E.2; CTS Action 7 requires verification that insertable i control rods are inserted. Therefore the proposed deviation from NUREG-1433 Action E.1 TS is not acceptable. Revise L.3 to be consistent with NUREG requirements. The response to this ]

RAI should be consistent with the response to RAI 3.3.1.1-16.

t Detroit Edison Response:

3.3.2.1-5 ITS Bases references DOC Comment: ITS proposes to adopt topical reports included in the ISTS. Although not specifically discussed in the licensee's submittal, the staff accepts the application of topical report NEDO-21231 because this report is referenced in section 15.4.9.6 of the UFSAR, the analysis for the control rod drop accident. Similarly, the staff accepts application of NEDC-30851 and NEDC-30851, Suppl. 2 because application of these topical reports was reviewed and approved by the NRC under Amendment No. 75 to the Fermi TS. However, the application of topical reports GENE-770-06-01 and GENE-770-06-01 has not been properly justified. Provide I

, , l l

references of staff safety evaluations approving these topical reports topical reports for use at  !

Fermi-2.

i This issue affects ITS 3.3.2.1,3.3.5.2,3.3.6.3, and 3.3.7.1. Note that for ITS 3.3.5.2, the staff approved the application of NEDC-30936 to the reactor core isolation cooling (RCIC) system instrumentation in Amendment No. 75. However, reference to GENE-770-06-02 in the Bases is not appropriate without staff approval of the application of that topical report to Fermi.

For the remaining LCOs, the licensee has adopted extended AOTs or SR frequencies that are based on GENE-770-06-01. Either adopt the CTS AOTs and SR frequencies or justify the i application of the topical report to Fermi 2. (See also RAls 3.3.6.3-1,3.3.7.1-1, and 3.3.7.1-6)

Detroit Edison Response:

3.3.6.2- 6 L.2 DOC L.2 concludes that ITS Required Actions C.1.1 and C.2.1 implement CTS Table 3.3.2-1, Actions 24 and 27 to require Secondary Containment Integrity be established with standby gas treatment operating. L.2 states that ITS Required Actions C.1.2 and C.2.2 provide options to declare the associated secondary containment isolation valves inoperable and/or declare ,

associated SGT subsystem inoperable. Further, L.2 concludes that these alternate Actions for the loss of secondary containment isolation function will ensure continued safe operation, consistent with the allowed actions for inoperabilities of the systems affected by the inoperable instrumentation. Therefore, this less restrictive change will have a negligible impact on safety.

Comment: ITS Actions provide three options to placing the plant in a safe condition if secondary containment isolation instrumentation cannot be restored to operable status or tripped. The options are to isolate secondary containment, or declare the secondary CIVs  ;

inoperable and start one SGT subsystem or declare SGT inoperable. Revise DOC L.2 to l discuss the less restrictive ITS requirements that result from replacing the requirement to establish Secondary Containment Integrity with standby gas treatment operating to each of the requirements provided by ITS required actions C.1, C.2 and C.3.

ITS LCO 3.3.7.1 3.3.7.1- 1 DOC M.4 JFD P.4 Comment: ITS Table 3.3.7.1-1 lists the requirements for the control room emergency filtration system (CREFS) instrumentation. Function 1 is Reactor Vessel Water Level- Low, Low Level 2

, Function 2 is drywell pressure and Function 3 is Fuel Pool Ventilation Exhaust - Radiation High. The FSAR assumes these functions initiate CREFS, but they do not appear in the CTS.

The ITS assigns the STS 24-hour repair AOT (Condition B) and 6-hour test AOT for each function and a 92-day test frequency for Functions 1 and 2. In the STS the 24-hour repair AOT, the 92-day surveillance test interval and the 6-hour test AOT are based on topical report GENE-770. The ITS justifications discussed in DOC M.4 and JFD P.4 do not establish a clear safety-basis for proposed CTS changes. M 4 is a general statement that the added functions do not impact safe operation of the plant. DOC P.4 states that GENE-770-01 in not adopted for Function 1 of CREFS. This P.4 statement implies that GENE-770 is adopted for Functions 2 and 3 since these functions share Condition B which allows a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> restoration time.

The proposed ITS Bases adopt the basis statements provided for the STS Actions without adopting the STS Actions. The proposed ITS Action B.2 24-hour repair AOT is retained from the STS but the STS action to " trip the channel" is replaced with " restore the channel." The 6-hour repair AOT in proposed ITS Action C.2 is retained from the STS but the STS action to " trip the channe!" is replaced with " restore the channel." The STS actions are based on the remaining redundancy and diversity of the instrumentation available to provide CREFS actuation. The STS repair AOTs are based on topical reports. The topical reports are referenced in the Bases without a DOC reference to a staff SE approving use of the topical reports for Fermi-2. Therefore, these preferences to changing the NUREG are not acceptable based on current documentation. (See also RAI 3.3.2.1-5)

Discussion of Change (DOC) LA.12 ITS Surveillance Requirement (SR) 3.3.1.1.17 Original Comment: The proposed CTS changes are not acceptable. The design sensor

! response time is the specified limit in CTS. This limit is based on staff review and acceptance of

- a topical report NEDO-32291 and must be retained in the note to SR 3.3.1.1.17. This precludes  !

substituting other topical report acceptance criteria such as historical data for response time  !

{ testing for manufacturers data. Revise SR 3.3.1.1.17 to include " design sensor response 1

time."

f Resolution: In the ITS, the portion of the CTS footriote related to design response time is

} relocated to the Bases. The staff has determined thPt the Bases provide adequate control of this parameter. Therefore, this question is resolved.

justification for the STS deviation. l Resolutic.1: The plant-specific design differences at Fermi 2 that led to this deviation from the l STS are explained in the Bases and in the Updated Final Safety Analysis Report.

3.3.1.1-22 STS SR 3.3.1.1.10 l Original Comment: STS SR 3.3.1.1.10 requires calibration of certain RPS trip units every 92 l days. ITS SR 3.3.1.1.10 changes the surveillance requirement to " verify the trip unit setpoint" l every 92 days. This requirement originated in CTS Table 4.3.1.1-1 as footnote k, to verify trip j unit set points as part of a channel functional test (CFT). It is assumed that the CTS CFT l provides instructions for out-of-tolerance trip settings, however, ITS SR 3.3.1.1.10 only requires

! verification of trip set points as a stand-alone requirement. The STS SR 3.3.1.1.10 requirement to " calibrate" the trip units is a more correct translation of the CTS requirement. Provide i

additional discussion and justification for the STS deviation, or implement the STS presentation of the surveillance requirement. (RAls 3.3.1.1-22, 3.3.5.1-1, 3.3.5.2-3, 3.3.6.1-3, 3.3.6.2-1, and 3.3.7.1-2 are related.)

l Resolution: The CTS requirement to verify the trip unit set point was reviewed and approved by the NRC in Amendment No. 75. The licensee carried this requirement over into ITS. The Bases describe what the verification entails, including reouirements to adjust the set point if it is outside the limits of the Allowable Value or the limits accounted for in the appropriate set point methodology. This is acceptable to the staff. This resolution applies to all six affected LCOs.

3.3.1.2-8 ITS SR 3.3.1.2.5 and SR 3.3.1.2.6 DOC A.2

, Original Comment: A Note is added to ITS SR 3.3.1.2.5 and SR 3.3.1.2.6 which deletes signal-to-noise ratio determination when the source range monitor (SRM) count rate is greater than, or equal to,3.0 cps. This change, classified as an administrative change (DOC A.2), actually resuhs in a less restrictive requirement, and should be discussed and justified as a less

! restrictive change. CTS 4.3.7.6 (c) and CTS 4.9.2 (c) require verification that the SRM count rate is at least 3.0 cps with the detector fully inserted, and does not omit the requirement to verify the count rate under any condition. Therefore, the Note added to ITS SR 3.3.1.2.5 and SR 3.3.1.2.6 is less restrictive. Addition of this SR Note also results in a deviation from the STS which is not technically justified. Provide additional discussion and justification for the less  ;

e 3e e turbine trip instrumentation (LCO 3.3.2.2). However, the ITS does not propose application of the )

l topical to this LCO. Provide additional discussion for this selective use of topical report AOT and '

surveillance test interval extensions.

Resolution: The application of GENE-770-06-01 has not been approved for Fermi 2.

Therefore, it would not be appropriate to apply this topical report to the feedwater main turbine trip instrumentation. This issue is addressed for the rod block instrumentation in 3.3.2.1-5.

3.3.2.2-2 CTS 3/4.3.9 Actions (b) and (c) l ITS ?. 3.2.2 C C C L.3 Comment: The iTS LCO 3.3.2.2 is writton for a three channel feedwater/ main turbine trip plant i design. Fermi-2 uses a 4 channel (one-out-two taken twice) 7.ctuation logic with a CTS AOT j allowance of 7 days for one inoperable channel and a 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> AOT allowance for two inoperable l channels.- LCO 3.0.3 applies if more than two channels are inoperable. The ITS proposes to I extend the CTS AOT to allow 7 days for a second inoperable channel as long as trip capability is l preserved. This proposed change deviates from the CTS and STS. The justification provided in DOC L.3 is based on NUREG-1433 as a " " standard" provisions for inoperabilities that result in the remaining Operable logic constituting a 2-out-of 2 trip." Revise L.3 to delete the reference to the NUREG as a pre-approved regulatory document for CTS changes and provide reliability and safety discussions to justify extending the repair time for the second inoperable channel to 7 days from 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.

l Resolution: During the December 1 through December 3,1998, meeting, the staff concluded j l that the proposed ITS is acceptable. In the STS, loss of one channel places the logic in a i two-out-of-two arrangement to trip. For Fermi, if one channel is inoperable in each of the trip i systems then the logic is also placed in a two-out-of-two arrangement to trip. Therefore, it is j appropriate to allow the 7-day AOT in this situation.

3.3.5.1- 4 ITS Action A, B and C Or8ginal Comment: CTS Action 30 applies to core spray, low pressure coolant injection and high pressure coolant injection instrument functions which detect plant conditions requiring

< emergency core cooling system (ECCS) actuation. Action 30 becomes Actions A, B and C in ITS. The Bases support the ITS 24-hour period to repair or trip inoperable channels as allowances that accommodates the Fermi 2 design for Functions 2.e,2.f and 2.g which detect breaks and Function 2.d for loop select logic. The Bases references topical report NEDC-30936-P-A. Provide a NEDC-30936-P-A citation giving the staff approved 24-hour repair or trip times, as applicable, for ITS functions 2.d. 2.e,2.f and 2.g.

Resolution: These functions were specifically addressed in the licensee submittal dated August 20,1990, for the application of the various topical reports on instrument test frequencies and allowed outage times. The staff reviewed and approved this application in Amendment No. 75 to the Fermi 2 TS.

Original Comment
STS LCO 3.3.6.1 includes repair allowances based on adopting NEDC-30851-P-A. Confirm that use of NEDC-30851 is approved for Fermi 2 CTS and provide l topical report NEDC-30851 citations to show that the topical report does not credit a 6-hour repair allowed outage time (AOT) for channels that when tripped would cause an isolation.

Revise DOC LC.1 to replace reference to ITS Action B with Action C. (See also 3.3.6.2-4)

Resolution: Amendment No. 75 reviewed and approved the application of this topical report to Fermi. The text of the topical report and its tables indicate that the staff approved a 12-hour repair AOT for isolation instruments common to RPS or to both RPS and ECCS and a 24-hour l

repair AOT for isolation instruments common to ECCS. However, the model TSs included the 6-hour AOT for those cases in which tripping the channel would cause the isolation. In the STS, only the 12-hour and 24-hour AOTs discussed in the topical report are applied. In the ITS, the licensee conforms to the topical report. Therefore, the ITS version .s acceptable. The issue of l references to Action B versus Action C is addressed in 3.3.6.1-5 (3.3.6.2-5). )
