(DRAFT) REQUEST FOR ADDITIONAL INFORMATION KEWAUNEE POWER STATION LICENSE AMENDMENT REQUEST (TAC No. ME7110):

MODIFYING THE TECHNICAL SPECIFICATIONS (TS) AND THE CURRENT LICENSING BASIS (CLB)

TO INCORPORATE CHANGES TO THE CURRENT RADIOLOGICAL ACCIDENT ANALYSIS (RAA) OF RECORD (KNOWN AS CHI-OVER-Q)

DOCKET NO. 50-305 By letter dated August 30, 2011, Dominion Energy Kewaunee (DEK) submitted a license amendment request (LAR)-244 (ADAMS Accession No. ML11252A521) to revise the Kewaunee Power Station (KPS) Operating License by modifying the Technical Specifications (TS) and the current licensing basis (CLB) to incorporate changes to the current radiological accident analysis (RAA) of record. This proposed amendment would revise the current RAA for the design-basis accidents (DBAs) described in Chapter 14 of the KPS Updated Safety Analysis Report (USAR). This amendment would also fulfill a commitment made to the NRC in response to Generic Letter 2003-01, Control Room Habitability.

In the course of their technical review, the Accident Dose Technical Branch (AADB and the Containment and Ventilation Technical Branch (SCVB) have requested further information items to enable completion of their respective Safety Evaluation efforts. These items are provided in draft form for you to review for clarification. We seek to confirm your understanding of the items and the determination of a firm date for response, typically within 30 days of the date of this Request for Additional Information (RAI). The items we seek are attached.

Please contact me by 5/17/2012 to confirm: (1) that the items are clear to you and to the responsive DEK staff without further discussion or (2) that a clarifying conference call is needed. Upon determination that the RAI items are clear and confirmation of when responses to these items are due, these draft RAI items will be considered to be in final form.

ME7110 is a complex project and we (Craig Sly of DEK and myself) have discussed methods for (1) improved movement of RAI information, (2) improved responsiveness to NRC staff requests, and (3) more flexibility for DEK to schedule RAI response activity, over that associated with more rigidly defined RAI milestone events. This and subsequent RAI traffic will be tracked by an individual identifier to provide the associated response by the individualized request by date.

Docketing will take place on groups of RAI item responses based on close completion schedules rather than close issuance schedules, as is now customary. Thus, if DEK can respond with individual information in 5 days, the request by date will be shortened and will be received sooner than the rest of the items, although its docketing event might coincide with the original set of items or with those RAI items originating from another Technical Branch.

We will periodically assess when this new process is of mutual benefit while conforming to the regulation for processing amendment requests and their associated RAIs.

The RAI items requested by SCVB (Reviewer Torres) are assigned the following tracking numbers.

ME7110-RAII-SCVB-Torres-004-2012-06-15 ME7110-RAII-SCVB-Torres-005-2012-06-15 ME7110-RAII-SCVB-Torres-006-2012-06-15 ME7110-RAII-SCVB-Torres-007-2012-06-15 ME7110-RAII-SCVB-Torres-008-2012-06-15 ME7110-RAII-SCVB-Torres-009-2012-06-15 ME7110-RAII-SCVB-Torres-010-2012-06-15 ME7110-RAII-SCVB-Torres-011-2012-06-15 ME7110-RAII-SCVB-Torres-012-2012-06-15 After reviewing the request for a license amendment to revise the technical specifications to adopt of TSTF-51, TSTF-312 & TSTF-448 for Kewaunee Power Station, the Containment and Ventilation Branch (SCVB) determined that additional information is needed in order to continue the review.

SCVB RAI 4 (ME7110-RAII-SCVB-Torres-004-2012-06-15)

As presented in Table 3.6-1 of Attachment 4, Basic Data and Assumptions for Locked Rotor Accident (LRA), unfiltered inleakage at 800 cfm is not assumed until the control room is isolated at 60 minutes following the onset of an accident. Provide justification for assuming zero inleakage during the first 60 minutes while the control room is not isolated, discuss the potential radiation dose from inleakage during this time period.

SCVB RAI 5 (ME7110-RAII-SCVB-Torres-005-2012-06-15)

Table 3.2-5 Basic Data and Assumptions for LOCA, identifies containment spray coverage as being 100%. Please define what you mean by containment spray coverage and identify the surfaces and surface area taken into consideration. Please justify the assumption of 100% spray coverage.

SCVB RAI 6 (ME7110-RAII-SCVB-Torres-006-2012-06-15)

There appears to be a dichotomy between some statements made in the LAR and the change requiring isolation of the alternate intake which is used to justify not crediting radiation monitor R-23 and removing it from technical specifications. The alternate control room intake could now be opened using the note in TS 3.7.10. The presence of the note challenges the provided justification for the removal of R-23 which partially relies on the permanent closure of the alternate control room intake. Please clarify the treatment of the alternate control room intake considering the following statements contained in the LAR.

Page 29 of Attachment 4 states: As a result of the analyses documented in this License Amendment Request (LAR), the alternate control room intake will be restricted from use. This restriction is required because of the X/Q that would result due to the close proximity of the alternate intake to various release points; one of which is < 10 m from the alternate intake.

Administrative controls will be in place to assure the alternate control room intake is closed and prohibit its use during normal operation, following an accident, or while moving recently irradiated fuel.

, page 73 states: A single Kewaunee Power Station (KPS) Fuel Handling Accident (FHA) scenario models the bounding FHA which does not credit mitigating systems (e.g.,

radiation monitor isolation, bypass and closure signals, or ventilation filtration) and maximizes source term, dispersion and dose. This bounding scenario provides the basis to allow all penetrations to be open under administrative control while moving recently irradiated fuel. The results of this analysis show that control room isolation is required prior to moving recently irradiated fuel assemblies in order to maintain operator dose within 5 rem TEDE.

Technical Specification (TS) 3.7.10, "Control Room Post Accident Recirculation (CRPAR)

System" contains a note that applies to openings in the CRE boundary that could be rapidly restored to the design condition, such as doors, dampers, hatches, floor plugs, and access panels. This Note only applies to openings in the CRE boundary that can be rapidly restored to the design condition, such as doors, dampers, hatches, floor plugs, and access panels.

SCVB RAI 7 (ME7110-RAII-SCVB-Torres-007-2012-06-15)

Given that Attachment 4 states that control room isolation is required in order to maintain operator dose within 5 rem TEDE (including the alternate control room intake) please confirm that the note will not be used to open the control room. If the control room is allowed to be opened, please provide the methodology that will be used to verify that the time to close the opening does not impact the design basis analyses and the methods which are being used to determine the time of closure and insure that the boundary integrity is restored to its design state (i.e. leakage is not greater than the design value). In addition, please state whether the methods used to perform this assessment includes all current design basis assumptions. If not, please state which assumptions are to be changed and justify not using the design bases to perform this assessment.

SCVB RAI 8 (ME7110-RAII-SCVB-Torres-008-2012-06-15)

The KPS UFSAR states: The operator can add fresh air to the Control Room under post-accident conditions by first verifying that conditions at the intake plenum will not cause contamination of the Control Room atmosphere, then manually opening the selected outside air damper and the damper at the suction of the post-accident recirculation fans. Excess air is exhausted to the Turbine Room through a backdraft damper. The operator can confirm the incoming fresh/recirculation air mix is not contaminating the Control Room atmosphere by observing a radiation monitor channel in the Control Room. Damper control switches are spring return to the normal position so that when the damper control switches are released the dampers automatically return to the recirculation configuration. (KPS UFSAR Rev 23, page 9.6-

12)

Since this is an isolation design, the control room needs to supplement the breathable air after a week to 10 days to keep the air habitable. Is the radiation monitor that being credited in the

UFSAR for fresh air the same monitor that being proposed to be removed from credit in the radiological analyses (R-23)? Since the radiological analyses assume that the control room will remain isolated throughout the accident and that no extra radiation (other than unfiltered inleakage) will enter the control room, how do you intend to monitor for fresh air?

Please note that in accordance to Safety Review Plan 6.4,Section III.3.IV which refers to duel inlets for the emergency zone, the NRC staff would not allow full credit for operator action to take in only un-contaminated air.

SCVB RAI 9 (ME7110-RAII-SCVB-Torres-009-2012-06-15)

TS 3.3.6-APPLICABILITY-In the Bases of TSTF-51 it is stated that The Manual Initiation, Automatic Logic and Actuation Relays, Containment Isolation - Phase A, and Containment Radiation Functions are required OPERABLE in MODES 1, 2, 3, and 4, and during movement of [recently] irradiated fuel assemblies [(i.e., fuel that has occupied part of a critical reactor core within the previous [x] days)] within containment. Under these conditions, the potential exists for an accident that could release significant fission product radioactivity into containment.

However, in your mark-up, dated July 25, 2011 (ML11222A123) the words an accident that could release significant is not included. In order to be in compliance with TSTF-51 please update your mark-up to include these words, or provide acceptable justification explaining why it is not necessary.

SCVB RAI 10 (ME7110-RAII-SCVB-Torres-010-2012-06-15)

The NRC staff understands that credit for the control room ventilation intake radiation monitor R-23, which provides control room isolation, is being removed. And that, only the current fuel handling accident (FHA) and locked rotor accident (LRA) events use and credit the R-23 system for control room isolation. The proposed new FHA requires that the control room be isolated prior to moving recently irradiated fuel therefore R-23 is no longer required for that accident. A proposed operator action will be required one hour following a LRA to isolate the control room.

You stated that one hour is sufficient time for the operator to identify the accident, take necessary emergency steps in response to the accident, and direct action to isolate the control room and start the control room post accident recirculation system (CRPARS). Please provide a discussion demonstrating continued compliance with 10 CFR 20.1701.

SCVB RAI 11 (ME7110-RAII-SCVB-Torres-011-2012-06-15)

In order for a licensee to correctly implement TSTF-51-A, Rev 2, it needs to include Insert O Reviewers Note into the Applicability Section of TS Bases 3.9-4 Containment Penetrations.

The proposed Bases for Kewaunee TS 3.9-4, omit the inclusion of such a note. The note requires that the licensee make a commitment consistent with draft NUMARC 93- 01, Revision 3, Section 11.2.6 Safety Assessment for Removal of Equipment from Service During Shutdown Condition, subheading Containment-Primary (PWR)/Secondary (BWR). The staff notes that in Page 26 of Attachement 2 to Kewaunees LAR dated August 30, 2011 (ADAMS No.

ML11252A651), the licensee has made an equivalent commitment to NUMARC 91-06 in regard to the assessment of fuel handling/core alterations, ventilation system and radiation monitor availability, with respect to the filtration and monitoring of releases from the fuel. If the note is not to be included, please justify the omission of Insert O in TS Bases 3.9-4. (Note: The NRC staff considers it acceptable to provide a Reviewers Note in the applicable TS bases committing to NUMARC 91-06)

SCVB RAI 12 (ME7110-RAII-SCVB-Torres-012-2012-06-15)

Included in Kewaunees LAR dated August 30, 2011(ADAMS No. ML11252A521) is a new TS Section 5.5 Programs and Manual. Subheading 5.5.9 Ventilation Filter testing Program (VFTP), to the associated TS states Demonstrate for each of the safety related systems listed below that an inplace test of the HEPA filters shows a penetration and system bypass < 1.0%

when tested in accordance with Regulatory Position C.5.c of the Regulatory Guide 1.52, Revision 2, and ANSI N510-1975 at the system flowrate specified below + 10%. The proposed penetration bypass is inconsistent with the bypass stated in Regulatory Position C.5.c in Reg Guide 1.52 Rev 2, which states The in-place DOP test for HEPA filters should conform to Section 10 of ANSI N510-1975 (Ref. 2). HEPA filter sections should be tested in place (1) initially, (2) at least once per 18 months thereafter, and (3) following painting, fire, or chemical release in any ventilation zone communicating with the system to confirm a penetration of less than 0.05% at rated flow.

In addition, subheading 5.5.9.b states Demonstrate for each of the safety related systems listed below that an inplace test of the charcoal adsorber shows a penetration and system bypass <

1.0% when tested in accordance with Regulatory Position C.5.d of the Regulatory Guide 1.52, Revision 2, and ANSI N510-1975 at the system flowrate specified below + 10%. Regulatory Position C.5.d of the Reg. Guide 1.52, Rev 2 states The activated carbon adsorber section should be leak tested with a gaseous halogenated hydrocarbon refrigerant in accordance with Section 12 of ANSI N510-1975 (Ref. 2) to ensure that bypass leakage through the adsorber section is less than 0.05%.

Please justify the proposed penetration and leakage bypass of < 1.0% taking into consideration that it differs from Regulatory Position C.5.c and C.5.d which states a penetration and leakage bypass of < 0.05%.
