MILLSTONE POWER STATION UNIT 3 SUPPLEMENT TO LICENSE AMENDMENT REQUEST TO RELOCATE TECHNICAL SPECIFICATION SURVEILLANCE FREQUENCIES TO LICENSEE CONTROLLED PROGRAM By letter dated July 5, 2011, Dominion Nuclear Connecticut, Inc. (DNC) submitted a license amendment request (LAR) for Millstone Power Station Unit 3 (MPS3). The proposed amendment would relocate certain technical specification (TS) surveillance frequencies to a licensee controlled program by adopting Technical Specification Task Force (TSTF)-425, Revision 3, "Relocate Surveillance Frequencies of Licensee Control
- Risk-Informed Technical Specification Task Force Initiative 5b." The proposed change would also add a new program, the Surveillance Frequency Control Program, to the TSs, in accordance with TSTF-425. TSTF-425 is approved for use by the U.S.
Nuclear Regulatory Commission (NRC) and was announced in the Federal Register on July 6, 2009 (74 FR 31996).
In a letter dated August 22, 2011, the NRC provided DNC an opportunity to supplement the LAR identified above. This was based on the NRC staffs acceptance review which identified proposed changes that did not meet the specific relocation criteria delineated in TSTF-425 Rev. 3. Due to schedule impacts associated with Hurricane Irene, the due date for this response was extended from September 7, 2011 to September 12, 2011. provides DNC's response to NRC letter dated August 22, 2011.
New marked-up TS and TS Bases pages for the revised changes are provided in Attachments 2 and 4, respectively, to replace the corresponding pages submitted previously. A revised Significant Hazards Consideration (SHC) Determination is provided in Attachment 3. The revised changes proposed herein do not affect the conclusion of the revised SHC.

Serial No.11-474 Docket No. 50-423 Supplement to SFCP Amendment Request Attachment 1, Page 1 of 4 Supplement to License Amendment Request To Relocate Technical Specification Surveillance Frequencies To Licensee Controlled Program By letter dated July 5, 2011, Dominion Nuclear Connecticut, Inc. (DNC) submitted a license amendment request (LAR) for Millstone Power Station Unit 3 (MPS3). The proposed amendment would relocate certain technical specification (TS) surveillance frequencies to a licensee controlled program by adopting Technical Specification Task Force (TSTF)-425, Revision 3, "Relocate Surveillance Frequencies of Licensee Control -
Risk-Informed Technical Specification Task Force Initiative 5b." The proposed change would also add a new program, the Surveillance Frequency Control Program, to the TSs, in accordance with TSTF-425. TSTF-425 is approved for use by the U.S. Nuclear Regulatory Commission (NRC) and was announced in the Federal Register on July 6, 2009 (74 FR 31996).
In a letter dated August 22, 2011, the NRC provided DNC an opportunity to supplement the LAR identified above. This was based on the NRC staff's acceptance review which identified proposed changes that did not meet the specific relocation criteria delineated in TSTF-425 Rev. 3. The proposed changes identified by the NRC that do not qualify for relocation are as follows:
Item 1 TS Table 4.3-3, "RadiationMonitoring Instrumentation for Plant Operations Surveillance Requirements," includes the MODES of applicability. Only surveillance frequencies meeting the requirements discussed above [exceptions listed in TSTF-425] may be relocated. Any unique information, such as the MODES of applicability,must be maintainedin the MPS3 TSs. Currently the entire table is proposed to be removed.
DNC Response The previously proposed changes to TS Table 4.3-3 have been revised to maintain TS Table 4.3-3 in TSs, including the MODES of applicability contained in the table.
Only the surveillance frequencies specified in TS Table 4.3-3 will be relocated. The new marked TS page for Table 4.3-3 is provided in Attachment 2.
Item 2 TS Table 4.3-6, "Remote Shutdown Monitoring InstrumentationSurveillance Requirements," does not require a channel calibrationof the Reactor Trip Breaker Indication instrument. The table also includes a note on Function No. 14, Source Range Count Rate, stating that the channel check is requiredbelow P-6 (intermediaterange neutron flux interlock setpoint). Only surveillance frequencies meeting the requirements discussed above may be relocated. Any unique
Serial No.11-474 Docket No. 50-423 Supplement to SFCP Amendment Request Attachment 1, Page 2 of 4 information must be maintainedin the MPS3 TSs. Currently DNC is proposing to remove the entire table.
DNC Response The previously proposed changes to TS Table 4.3-6 have been revised to maintain TS Table 4.3-6 in TSs, including the unique information identified above. Only the surveillance frequencies specified in TS Table 4.3-6 will be relocated. The new marked TS page for Table 4.3-6 is provided in Attachment 2.
Item 3 TS Table 4.3-7, "AccidentMonitoring Instrumentation Surveillance Requirements,"
contains two notes regardingthe channel calibrations(not the frequency of the channel calibration). Only surveillance frequencies meeting the requirements discussed above may be relocated. Any unique information must be maintainedin the MPS3 TSs. Currently DNC is proposingto remove the entire table.
DNC Response The previously proposed changes to TS Table 4.3-7 have been revised to maintain TS Table 4.3-7 in TSs, including the unique information identified above. Only the surveillance frequencies specified in TS Table 4.3-7 will be relocated. The new marked TS pages for Table 4.3-7 are provided in Attachment 2.
Item 4 TS Table 4.7-1, "SecondaryCoolant System Specific Activity Sample and Analysis Program,"requires Isotopic Analysis for Dose Equivalent 1-131 Concentrationat varying frequencies dependent on the Gross RadioactivityDetermination. The threshold cannot be relocatedand must be retainedin TSs. Currently DNC is proposing to remove the entire table.
DNC Response The proposed changes to TS Table 4.7-1 have been revised to maintain TS Table 4.7-1 in TSs, including the concentration thresholds in the table. Only the surveillance frequencies specified in TS Table 4.7-1 will be relocated. The new marked TS page for Table 4.7-1 is provided in Attachment 2.
Item 5 TS SR [surveillance requirement]4.1.1.1.2.1 (b), describes some of the requirements associatedwith an inoperable control rod(s). The SR is event-driven with a time component requiring that shutdown margin shall be determined acceptable, with increasedallowance for the withdrawn worth of the immovable or untrippablecontrol rod(s), with considerationfor several factors every 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
CurrentlyDNC is proposing to relocate this event-driven SR.
Serial No.11-474 Docket No. 50-423 Supplement to SFCP Amendment Request Attachment 1, Page 3 of 4 DNC Response In this case, the presence of the word "and" in the preceding SR (i.e., 4.1.1.1.2.1a) is not intended to be a logical connector which places the constraints of this event-driven surveillance on the remaining portion of the surveillance (i.e., 4.1.1.1.2.lb).
Station procedures require SR 4.1.1.1.2. lb to be performed at the specified frequency while in Modes 3, 4 and 5 and is not event-driven; therefore, no change to the original markup is required.
This situation (where use of the words "and" and "or" are not intended to be used as logical connectors) also applies to the following SRs: 4.1.1.2.1, 4.1.3.5, 4.2.2.1.2d, 4.2.2.1.4d, 4.2.3.1.2, 4.2.3.1.3, 4.4.9.3.1a, 4.5.2g, 4.6.5.1.1. Accordingly, no changes to the previously submitted markups are required.
Item 6 In addition, DNC is proposing to make changes outside of the scope of the model submittal (74 FR 31996). These additionalchanges were not addressed in the Significant Hazards Consideration. Please submit a supplement to the Significant Hazards Considerationto address these additionalchanges.
DNC Response A revised Significant Hazards Consideration (SHC) Determination is provided in Attachment 3. This revised SHC addresses the MPS3 specific surveillance frequencies that are outside of the scope of the model submittal (74 FR 31996).
Along with the corrections described above, additional replacement pages are included in Attachment 2 to correct or amend the TS markups previously submitted in the July 5, 2011 LAR. As a result of the changes proposed in this supplement, certain markups previously submitted are no longer necessary. These pages are provided in Attachment 2 and labeled "For Information Only" to identify the pages which can be removed from the July 5, 2011 submittal.

MILLSTONE POWER STATION UNIT 3
Serial No.11-474 Docket No. 50-423 Supplement to SFCP Amendment Request Attachment 3, Page 1 of 2 REVISED NO SIGNIFICANT HAZARDS CONSIDERATION Description of Amendment Request:
This amendment request involves the adoption of approved changes to the standard technical specifications (STS) for Westinghouse Pressurized Water Reactors (NUREG-1431), to allow relocation of specific technical specification (TS) surveillance frequencies to a licensee controlled program. The proposed changes are described in Technical Specification Task Force (TSTF) Traveler, TSTF-425, Revision 3 (ADAMS Accession No. ML090850642), "Relocate Surveillance Frequencies to Licensee Control - RITSTF Initiative 5b" and are described in the Notice of Availability published in the Federal Register on July 6, 2009 (74 FR 31996).
The proposed changes are consistent with NRC-approved Industry/lTSTF Traveler, TSTF-425, Revision 3, "Relocate Surveillance Frequencies to Licensee Control-RITSTF Initiative 5b." For MPS3 plant-specific surveillances not included in the NUREG-1431 mark-ups provided in TSTF-425 (identified in Attachment 4), DNC has determined that since these surveillances involve fixed periodic frequencies, relocation of these frequencies is consistent with TSTF-425, Rev. 3, and with the NRC's model safety evaluation dated July 6, 2009 (74 FR 31996), including the scope exclusions identified in Section 1.0, "Introduction," of the model safety evaluation.
The proposed changes relocate surveillance frequencies to a licensee controlled program, the Surveillance Frequency Control Program (SFCP). The changes are applicable to licensees using probabilistic risk guidelines contained in NRC-approved NEI 04-10, "Risk-Informed Technical Specifications Initiative 5b, Risk-Informed Method for Control of Surveillance Frequencies," (ADAMS Accession No. 071360456). In addition, administrative/editorial deviations of the TSTF-425 inserts and the existing TS wording are being proposed to fit the custom TS format.
Basis for proposed no significant hazards consideration: As required by 10 CFR 50.91 (a), the Dominion analysis of the issue of no significant hazards consideration is presented below:
- 1. Do the proposed changes involve a significant increase in the probability or consequences of any accident previously evaluated?
Response: No.
The proposed changes relocate the specified frequencies for periodic surveillance requirements to licensee control under a new Surveillance Frequency Control Program. Surveillance frequencies are not an initiator to any accident previously evaluated. As a result, the probability of any accident previously evaluated is not significantly increased. The systems and components required by the TSs for which the surveillance frequencies are relocated are still required to be operable, meet the acceptance criteria for the surveillance requirements, and be capable of performing any mitigation function assumed in the accident analysis. As a result, the consequences of any accident previously evaluated are not significantly increased.
Therefore, the proposed changes do not involve a significant increase in the probability or consequences of an accident previously evaluated.
Serial No.11-474 Docket No. 50-423 Supplement to SFCP Amendment Request Attachment 3, Page 2 of 2
- 2. Do the proposed changes create the possibility of a new or different kind of accident from any previously evaluated?
Response: No.
No new or different accidents result from utilizing the proposed changes. The changes do not involve a physical alteration of the plant (i.e., no new or different type of equipment will be installed) or a change in the methods governing normal plant operation. In addition, the changes do not impose any new or different requirements. The changes do not alter assumptions made in the safety analysis. The proposed changes are consistent with the safety analysis assumptions and current plant operating practice.
Therefore, the proposed changes do not create the possibility of a new or different kind of accident from any accident previously evaluated.
- 3. Do the proposed changes involve a significant reduction in the margin of safety?
Response: No.
The design, operation, testing methods, and acceptance criteria for systems, structures, and components (SSCs), specified in applicable codes and standards (or alternatives approved for use by the NRC) will continue to be met as described in the plant licensing basis (including the final safety analysis report and bases to TS), since these are not affected by changes to the surveillance frequencies. Similarly, there is no impact to safety analysis acceptance criteria as described in the plant licensing basis. To evaluate a change in the relocated surveillance frequency, Dominion will perform a probabilistic risk evaluation using the guidance contained in NRC approved NEI 04-10, Rev. 1, in accordance with the TS SFCP. NEI 04-10, Rev. 1, methodology provides reasonable acceptance guidelines and methods for evaluating the risk increase of proposed changes to surveillance frequencies consistent with Regulatory Guide 1.177.
Therefore, the proposed changes do not involve a significant reduction in a margin of safety.
Based upon the reasoning presented above, Dominion concludes that the requested changes do not involve a significant hazards consideration as set forth in 10 CFR 50.92(c), Issuance of Amendment.

3/4.2.2 and 3/4.2.3 HEAT FLUX HOT CHANNEL FACTOR and RCS FLOW RATE AND NUCLEAR ENTHALPY RISE HOT CHANNEL FACTOR The limits on heat flux hot channel factor, RCS flow rate, and nuclear enthalpy rise hot channel factor ensure that: (1) the design limits on peak local power density and minimum DNBR are not exceeded and (2) in the event of a LOCA the peak fuel clad temperature will not exceed the 2200'F ECCS acceptance criteria limit.
Each of these is measurable but will normally only be determined periodically as specified in Specifications 4.2.2 and 4.2.3. This periodic surveillance is sufficient to ensure that the limits are maintained provided:
- a. Control rods in a single group move together with no individual rod insertion differing by more than +/-12 steps, indicated, from the group demand position;
- b. Control rod groups are sequenced with overlapping groups as described in Specification 3.1.3.6;
- c. The control rod insertion limits of Specifications 3.1.3.5 and 3.1.3.6 are maintained; and
- d. The axial power distribution, expressed in terms of AXIAL FLUX DIFFERENCE, is maintained within the limits.
FNAH will be maintained within its limits provided Conditions a. through d. above are maintained. The relaxation of FNAH as a function of THERMAL POWER allows changes in the radial power shape for all permissible rod insertion limits.
The FNAH as calculated in Specification 3.2.3.1 is used in the various accident analyses where FNAH influences parameters other than DNBR, e.g., peak clad temperature, and thus is the maximum "as measured" value allowed.
The RCS total flow rate and FNAH are specified in the CORE OPERATING LIMITS REPORT (COLR) to provide operating and analysis flexibility from cycle to cycle. However, the minimum RCS flow rate, that is based on 10% steam generator tube plugging, is retained in the Technical Specifications.

Margin is maintained between the safety analysis limit DNB nd t design limit DNBR. This margin is more than sufficient to offset the effect of rod bow nd an other DNB penalties that may occur. The remaining margin is available for plant de gn flex* ility.
When an FQ measurement is taken, an allowance for bo experim ntal error and manufacturing tolerance must be made. An allowance of 5% is appr nate for a ull core map taken with the incore detector flux mapping system and a 3% allow nce is appr riate for manufacturing tolerance.
The heat flux hot channel factor, FQ(Z), is measued periodically sing the incore detector system.
These measurements are generally taken with e core at or near steady state conditions. Using the measured three dimensional power distri tions, it is possible to derive FQM(Z), a computed value of FQ(Z). However, because this val represents a steady state condition, it does not include the variations in the value of FQ( that are present during nonequilibrium situations.
To account for these possible variation the steady state limit of FQ(Z) is adjusted by an elevation dependent factor appropriate to either OC or base load operation, W(Z) or W(Z)BL, that accounts for the calculated worst ca e transient conditions. The W(Z) and W(Z)BL, factors described above for normal operat' n are specified in the COLR per Specification 6.9.1.6. Core monitoring and control under no steady state conditions are accomplished by operating the core within the limits of the appropr' te LCOs, including the limits on AFD, QPTR, and control rod insertion. Evaluation of the s ady state FQ(Z) limit is performed in Specification 4.2.2.1.2.b and 4.2.2.1.4.b while evaluation onequilibrium limits are performed in Specification 4.2.2.1.2.c and 4.2.2.1.4.c.
When RCS flow rate a d FNAH are measured, no additional allowances are necessary prior to comparison with the imits of the Limiting Condition for Operation. Measurement errors for RCS total flow rate nd for FNAH have been taken into account in determination of the design DNBR value.
The measureme t error for RCS total flow rate is based upon performing a precision heat balance and using the suit to calibrate the RCS flow rate indicators. To perform the precision heat balance, the strumentation used for determination of steam pressure, feedwater pressure, feedwater perature, and feedwater venturi AP in the calorimetric calculations shall be calibrated at lcaet cn.- per I8 menths. Potential fouling of the feedwater venturi which might not be detected could bias the result from the precision heat balance in a non-conservative manner.
Any fouling which might bias the RCS flow rate measurement can be detected by monitoring and 4 trending various plant performance parameters. If detected, action shall be taken before performing subsequent precision heat balance measurements, i.e., either the effect of the fouling shall be quantified and compensated for in the RCS flow rate measurement or the venturi shall be cleaned to eliminate the fouling.

For slave relays, or any auxiliary relays in ESFAS circuits that are of the type Potter & Brumfield MDR series relays, the SLAVE RELAY TEST is performed at an "R" frequency (at least once every 18 months) provided the relays meet the reliability assessment criteria presented in WCAP-13878, "Reliability Assessment of Potter and Brumfield MDR series relays," and WCAP-13900, "Extension of Slave Relay Surveillance Test Intervals." The reliability assessments performed as part of the aforementioned WCAPs are relay specific and apply only to Potter and Brumfield MDR series relays. Note that for normally energized applications, the relays may have to be replaced periodically in accordance with the guidance given in WCAP-13878 for MDR relays.
REACTOR TRIP BREAKER This trip function applies to the reactor trip breakers (RTBs) exclusive of individual trip mechanisms. The LCO requires two OPERABLE trains of trip breakers. A trip breaker train consists of all trip breakers associated with a single RTS logic train that are racked in, closed, and capable of supplying power to the control rod drive (CRD) system. Thus, the train may consist of the main breaker, bypass breaker, or main breaker and bypass breaker, depending upon the system configuration. Two OPERABLE trains ensure no single random failure can disable the RTS trip capability.
These trip functions must be OPERABLE in MODE 1 or 2 when the reactor is critical. In MODE 3, 4, or 5, these RTS trip functions must be OPERABLE when the RTBs or associated bypass breakers are closed, and the CRD system is capable of rod withdrawal.
BYPASSED CHANNEL* - Technical Specifications 3.3.1 and 3.3.2 often allow the bypassing of instrument channels in the case of an inoperable instrument or for surveillance testing.
A BYPASSED CHANNEL shall be a channel which is:

The Emergency Core Cooling System (ECCS) has several piping cross connection points for use during the post-LOCA recirculation phase of operation. These cross-connection points allow the Recirculation Spray System (RSS) to supply water from the containment sump to the safety injection and charging pumps. The RSS has the capability to supply both Train A and B safety injection pumps and both Train A and B charging pumps. Operator action is required to position valves to establish flow from the containment sump through the RSS subsystems to the safety injection and charging pumps since the valves are not automatically repositioned. The quarterly stroke testing (Technical Specification 4.0.5) of the ECC/RSS recirculation flowpath valves discussed below will not result in subsystem inoperability (except due to other equipment manipulations to support valve testing) since these valves are manually aligned in accordance with the Emergency Operating Procedures (EOPs) to establish the recirculation flowpaths. It is expected the valves will be returned to the normal pre-test position following termination of the surveillance testing in response to the accident. Failure to restore any valve to the normal pre-test position will be indicated to the Control Room Operators when the ESF status panels are checked, as directed by the EOPs. The EOPs direct the Control Room Operators to check the ESF status panels early in the event to ensure proper equipment alignment. Sufficient time before the recirculation flowpath is required is expected to be available for operator action to position any valves that have not been restored to the pretest position, including localmanual valve operation. Even if the valves are not restored to the pre-test position, sufficient capability will remain to meet ECCS post-LOCA recirculation requirements. As a result, stroke testing of the ECCS recirculation valves discussed below will not result in a loss of system independence or redundancy, and both ECCS subsystems will remain OPERABLE.
When performing the quarterly stroke test of 3SIH*MV8923A, the control switch for safety injection pump 3SIH*PIA is placed in the pull-to-lock position to prevent an automatic pump start with the suction valve closed. With the control switch for 3SIH*PIA in pull-to-lock, the Train A ECCS subsystem is inoperable and Technical Specification 3.5.2, ACTION a., applies. This ACTION statement is sufficient to administratively control the plant configuration with the automatic start of 3SIH*P1A defeated to allow stroke testing of 3SIH*MV8923A. In addition, the EOPs and the ESF status panels will identify this abnormal plant configuration, if not corrected following the termination of the surveillance testing, to the plant operators to allow restoration of the normal post-LOCA recirculation flowpath. Even if system restoration is not accomplished, sufficient equipment will be available to perform all ECCS and RSS injection and recirculation functions, provided no additional ECCS or RSS equipment is inoperable, and an additional single failure does not occur (an acceptable assumption since the Technical Specification ACTION statement limits the plant configuration time such that no additional equipment failure need be postulated). During the injection phase the redundant subsystem (Train B) is fully functional, as is a significant portion of the Train A subsystem. During the recirculation phase, the Train A RSS subsystem can supply water from the containment sump to the Train A MILLSTONE - UNIT 3 B 3/4 5-2b Amendment No. +-00, 4-7, 445-7

3/4.7.6 DELETED 3/4.7.7 CONTROL ROOM EMERGENCY VENTILATION SYSTEM BACKGROUND The control room emergency ventilation system provides a protected environment from which operators can control the unit following an uncontrolled release of radioactivity, hazardous chemicals, or smoke. Additionally, the system provides temperature control for the control room envelope (CRE) during normal and post-accident operations.
The control room emergency ventilation system is comprised of the CRE emergency air filtration system and a temperature control system.
The control room emergency air filtration system consists of two redundant systems that recirculate and filter the air in the CRE and a CRE boundary that limits the inleakage of unfiltered air. Each control room emergency air filtration system consists of a moisture separator, electric 4' heater, prefilter, upstream high efficiency particulate air (HEPA) filter, charcoal adsorber, downstream HEPA filter, and fan. Additionally, ductwork, valves or dampers, and instrumentation form part of the system.
The CRE is the area within the confines of the CRE boundary that contains the spaces that control room occupants inhabit to control the unit during normal and accident conditions. This area encompasses the control room, and other non-critical areas including adjacent support offices, MILLSTONE - UNIT 3 B 3/4 7-10 Amendment No. 44-9, 446, 444, 244,
