MILLSTONE POWER STATION UNIT 3

Serial No.13-138 Docket No. 50-423 Attachment 1, Page 1 of 8 By letter dated October 4, 2012, 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 to Licensee Control

- RITSTF [Risk-Informed Technical Specification Task Force Initiative] 5b." The proposed change would also add a new program, the Surveillance Frequency Control Program (SFCP), in accordance with TSTF-425. In a letter dated December 18, 2012, the NRC transmitted a request for additional information (RAI) to DNC related to the LAR. DNC responded to the RAI in a letter dated January 4, 2013. In a letter dated March 8, 2013, the NRC transmitted a second RAI to DNC related to the LAR. This attachment provides DNC's response to the NRC's RAI.

Question 1 The response to Question 5 of the RAI, dated January 4, 2013, discussed a process and noted a procedure. However, the response is future-looking, and the question is related to what has been done to-date to support the application. The original question is repeated. Gap #2. The disposition of this supporting requirements states this is a documentation issue only; however, no discussion is provided on the plant walkdowns and interviews mentioned in the supporting requirement. Please discuss these walkdowns and interviews which address this supportingrequirement (SR).

DNC Response System engineer interviews have been completed and documented to confirm the system analysis correctly reflects the as-built, as-operated plant for the following systems:

" Circulating Water System

  • Chemical and Volume Control System
  • High Pressure Safety Injection System
  • Reactor Plant Component Cooling Water System

" Service Water System The feedback provided in the interviews has been incorporated into the appropriate model notebooks and model files. The feedback for these systems was primarily editorial and did not have a significant impact on the model.

System walkdowns have also been completed and documented to confirm the system analysis correctly reflects the as-built, as-operated plant for the following systems:

  • Charging Pump Cooling System

Serial No.13-138 Docket No. 50-423 Attachment 1, Page 2 of 8

" Chemical and Volume Control System

" Reactor Plant Component Cooling Water System

" Safety Injection Pump Cooling System Walkdowns of these systems did not identify any modeling or documentation issues.

Question 2 The response to Question 6 of the RAI, dated January 4, 2013, states that Gap #3 (HR-G5) is based on outdated (circa 2006) talk-through documentation with Operations, and proposes to perform a sensitivity analysis on human errorprobabilities (HEPs) in lieu of updating operator survey information to support the basis for revised or new human failure events. The license amendment request proposes to use a sensitivity analysis using an a-priori multiple of 10; however, this a-prior approach cannot be known to represent a bounding sensitivity analyses for the HEPs. Therefore, since the last update to the HEPs which considered operatorsurvey information was performed a long time ago, ether complete the talk-throughs or provide assurance that the HEPs will be treatedin a bounding manner.

DNC Response Question 6 of the RAI, dated January 4, 2013, is associated with a technical adequacy gap in the ASME/ANS Supporting Requirement (SR) HR-G5 Category II, which states:

"When needed, BASE the required time to complete actions for significant

[human failure events] HFEs on action time measurements in either walkthroughs or talkthroughs of the procedures or simulator observations."

In 2012, a focused probabilistic risk assessment (PRA) peer review identified the MPS3 PRA model, M310A, did not meet the category II requirements for HR-G5. The peer review team identified the existing human reliability analysis documentation for talkthroughs with Operations was outdated (circa 2006). In addition, no new operator survey information was provided to support the basis for revised or new HFEs.

In March 2013, an operator walkthrough/talkthrough was performed with a MPS3 Operations Unit Supervisor for the significant HFEs as required to meet ASME/ANS SR HR-G5. In addition, operator walkthrough/talkthrough of the non-significant HFEs were performed. The [Electric Power Research Institute] EPRI HRA Calculator for MPS3 was revised to include the changes identified during the walkthrough/talkthrough. The final analysis resulted in no impact to the HEP values within the MPS3 PRA model.

Therefore, no sensitivity studies will be required to address SR HR-G5.

Serial No.13-138 Docket No. 50-423 Attachment 1, Page 3 of 8 Question 3 In response to Question 7 of the RAI, dated January 4, 2013, it is noted that the MPS3 probabilistic risk assessment (PRA) Internal Flooding notebook states: "Thus, only equipment within the area that may be affected by spray or jet impingement damage are assumed to fail, and there is no propagation to other areas and no damage due to submersion." Providejustification for the assumption that action can be taken such that there is no propagationor submersion.

DNC Response The flooding zones within MPS3 have been re-evaluated to augment the modeling of human-induced flooding events during maintenance activities. The review identified five flood areas and flood sources where new maintenance-induced flooding events could potentially occur. When these new events were added to the model, collectively, the average maintenance core damage frequency (CDF) and large early release frequency (LERF) values increase by significantly less than 1%. Since the MPS3 PRA, M310A has not been updated to include the newly identified maintenance-induced flooding events, a sensitivity study will be performed when needed to support PRA assessments in the SFCP.

The sentence referenced in the RAI from the MPS3 PRA Internal Flooding notebook IF.2 has been revised to state, "Flood zones have been assessed to ensure that spray, jet impingement, submersion, and propagation were evaluated and documented as required."

Question 4 Gap #9 is related to the potential for flood barrier unavailability and flood pathways through floor drain check valves. Please discuss your assessment and the risk significance of the flood barrierunavailability and the floor drain check valves for the application in more detail, as well as planned updates, if necessary, to the flood PRA model based on the assessment.

DNC Response Technical adequacy Gap #9 is associated with ASME/ANS SR IFSN-A8 Category II, which states:

"IDENTIFY inter-area propagation through the normal flow path from one area to another via drain lines; and areas connected via backflow through drain lines involving failed check valves, pipe and cable penetrations (including cable trays),

doors, stairwells, hatchways, and [heating, ventilation and air conditioning] HVAC

Serial No.13-138 Docket No. 50-423 Attachment 1, Page 4 of 8 ducts. INCLUDE potential for structural failure (e.g., of doors or walls) due to flooding loads."

The 2012 focused peer review team stated, "There are indications throughout the IF.1 and IF.2 documents that inter-area propagation was appropriately considered, although there is no single location in one of the documents where inter-area propagation paths are listed."

The MPS3 internal flooding notebooks (IF.1 and IF.2) have been revised to support easier retrieval and understanding of inter-area propagation through normal flow paths, including drain line backflow and potential flood barrier structural failure/unavailability. A review of the inter-area propagation paths did not identify any new flooding events.

Revision of the documentation addresses the peer review's findings and no update to Model M310A is planned or necessary.

Question 5 For fire events and external events risk assessment, responses to Questions 10 and 11 of the RAI, dated January 4, 2013, state that information from the Millstone Individual Plant Examination of External Events (IPEEE) report will be screened. In addition, the responses to Questions 10 and 11 of the previous RAI indicate that the IPEEE information will be qualitativelyassessed.

a. Please clarify which methods (e.g., an IPEEE method or other)would be used if a bounding analysis is to be performed for fire events or extemal events.
b. If a bounding analysis is to be performed for fire events or external events, discuss steps of your analysis process which help to ensure the analysis is bounding and considers the currentplant configurationand operation DNC Response DNC is committed to evaluating changes to surveillance frequencies in accordance with the guidance provided in NEI 04-10, Rev. 1. NEI 04-10 methodology allows a qualitative screening or bounding analysis to provide justification for acceptability of proposed surveillance frequency changes. Since the MPS3 PRA model does not currently include fire and other external events, the NEI 04-10 guidance will be used to evaluate the potential risk impact of external events associated with surveillance frequency changes. Specifically, external event information from the Millstone Individual Plant Examination of External Events (IPEEE) report will be initially screened.

The information will be reviewed and qualitatively assessed based on engineering judgment to determine the impact of the external events on surveillance frequency changes. If the qualitative information is deemed not to be sufficient then a bounding analysis will be performed.

Serial No.13-138 Docket No. 50-423 Attachment 1, Page 5 of 8 DNC will perform bounding analysis in accordance with Step 10b, Bounding Analysis Below IE-07/yr CDF and 1E-08/yrLERF?, of NEI 04-10 Rev. 1, which states, in part:

"Alternative evaluations for the impact from external events and shutdown events are also deemed acceptable at this point. For example, if the ACDF and ALERF values have been demonstrated to be very small from an internal events perspective based on detailed analysis of the impact of the SSC being evaluated for the STI change, and if it is known that the CDF or LERF impact from external events (or shutdown events as applicable) is not specifically sensitive to the SSC being evaluated (by qualitative reasoning), then the detailed internal events evaluations and associated required sensitivity cases ... can be used to bound the potential impact from external events and shutdown PRA model contributors.

As an another example, if the ACDF and ALERF values have been demonstrated to be very small from an internal events perspective based on detailed analysis of the impact of the SSC being evaluated for the STI change, and if it is known that the plant CDF and LERF results of the external event or shutdown PRA are much smaller than the corresponding values for the internal event full power PRA, (that is, less than 10%), then the results of the internal events analysis alone would suffice for the STI consideration."

If the above NEI 04-10 guidance is not sufficient to address the bounding analysis requirements, then a quantitative bounding analysis will be performed using tools currently in use to support the Significance Determination Process (SDP). For example, in recent years Dominion has performed several fire PRA evaluations and would implement the same process for any STI changes, if necessary.

1. The IPEEE fire analysis will be reviewed to determine whether the SSCs associated with the STI may impact fire risk.
2. If the STI will be fire risk impacting, a fire PRA bounding analysis will be developed to allow calculation of the delta risk by generating an accident sequence analysis that credits the affected SSCs. The bounding fire analysis will be based on IPEEE methodologies to calculate fire initiating event frequencies and will use mitigating system and operator action analyses completed for the current internal events MPS3 PRA model. This will ensure the analysis reflects the current plant configuration and operation.
3. Then sensitivity calculations will be performed using the accident sequence model to calculate the STI change delta CDF and delta LERF and to identify dominant fire risk contributors associated with the STI change.
4. Reasonable variations to the appropriate basic event values associated with the dominant fire risk contributors will then be made to determine the potential bounding fire risk impact of the STI change. This bounding evaluation process is consistent with the guidance provided in NEI 04-10, Step 1Ob. The basis for the changes made will be documented in the PRA analysis supporting the STI change.

Serial No.13-138 Docket No. 50-423 Attachment 1, Page 6 of 8

5. The delta CDF and delta LERF results of the sensitivity calculations will be compared to 1 E-7/yr CDF and 1E-8/yr LERF.

The process outlined above will be used for required bounding analysis of other external events.

Question 6 SR 4.2.4.2 is only performed if >75% power AND one power range channel is inoperable (Frequenciesthat are related to specific condition) and cannot be relocated to the Surveillance Frequency Control Program (SFCP).[Part 1] Also, Table 4.7.1, Secondary Coolant System Specific Activity Sample and Analysis Program,proposes to relocate a "ProgramFrequency"to the SFCP. This is prohibitedbecause it is a program requirement (Frequencies that reference other approved programs for the specific interval).[Part 2] And even if they could be relocated, note that 2(a) and (b) are conditional (SR performance is dependent upon on (1) Gross Radioactivity Determination SR results. I had a similar issue with the Oconee TSTF-425 license amendment request where the licensee proposed relocating an Oconee TS Chapter 5 component "test interval," that is located in the Standard Technical Specification (Section 3, Surveillance), to the SFCP.[Part3]

DNC Response Part 1 Because of format variations in the MPS3 TSs (NUREG -0452 format), the frequency in SR 4.2.4.2, Quadrant Power Tilt Ratio [QPTR] appears conditional; however, comparison of this surveillance with the QTPR surveillance in TSTF-425 (i.e., SR 3.2.4.2) for Westinghouse plants (NUREG-1431 format) shows that these surveillance requirements are identical, therefore, permitted to be relocated to the SFCP.

Part 2 The approved programs for MPS3 are described in Section 6.0, "Administrative Controls," of the MPS3 TSs. The title descriptor in Table 4.7.1 (i.e., Secondary Coolant System Specific Activity Sample and Analysis "Program.") may be misconstrued since there are no program requirements for secondary coolant specific activity sampling and analysis in Section 6.0 of the TSs. To preclude future misunderstanding, DNC proposes to delete the word 'Program" from the title in Table 4.7.1. This change is reflected in the mark-up for Table 4.7-1 provided in Attachment 2.

Serial No.13-138 Docket No. 50-423 Attachment 1, Page 7 of 8 Part 3 In DNC's submittal of October 4, 2012, DNC proposed to relocate the surveillance frequencies contained in Section 2a and 2b of Table 4.7-.1 to the SFCP. The NRC states above that these frequencies are conditional and therefore cannot be relocated to the SFCP. Upon review of these requirements, DNC agrees that the frequency in Section 2a is conditional and not a candidate for relocation. However, the frequency in Section 2b is associated with the normal condition of dose equivalent 1-131 < 10% of allowable limit and therefore can be relocated to the SFCP. This is consistent with the standard TSs changes for dose equivalent 1-131 (i.e., SR 3.7.18.1) presented in TSTF-425 for Westinghouse plants. The revised mark-up for Table 4.7-1 is provided in .

Question 7 The response to Question 13 of the RAI, dated January4, 2013, is unacceptable. The Frequency (the "when') can be located in the SFCP - NOT the Surveillance Requirement ("what" is being tested) i.e., "each train shall be tested." This is very clearly identified in the FR Notice for Availability. The frequency (62 days) and the reference to the staggered'test basis can be replaced by "the frequency specified in the Surveillance Frequency Control Program," as the licensee identified in the RAI response.

DNC Response The proposed TS mark-ups for Table 4.3-1 (i.e., Notation 7) and Table 4.3-2 (i.e.,

Notation 1) have been revised to relocate the surveillance frequency to the SFCP while still maintaining reference on "what is being tested." Since these table notations are no longer being deleted in their entirety, the notation numbers have been added back into the applicable table.

Similarly, the markup for SR 4.3.1.2 has been revised to address the same issue described above in Question 7. Specifically, the surveillance frequency in SR 4.3.1.2 is still proposed for relocation; however, the requirement on what to test is being maintained.

The revised marked-up TS pages reflecting these changes are provided in Attachment 2.

Additional Information During the RAI clarification call between the NRC and DNC on February 5, 2013, the NRC questioned relocating the surveillance frequencies for SRs 4.4.1.2.1, 4.4.1.3.1 and 4.4.1.4.1.3 to the SFCP since the frequencies appeared to be conditional/event-driven.

Serial No.13-138 Docket No. 50-423 Attachment 1, Page 8 of 8 Upon review of these surveillances, DNC concludes that relocation of these surveillance frequencies to the SFCP is consistent with the TSTF-425 changes for Westinghouse plants (see SRs 3.4.5.3, 3.4.6.3 and 3.4.7.3) and therefore qualifies for relocation.

In addition, DNC has reviewed the MPS3 TS markups submitted to the NRC in letter dated October 4, 2012, to ensure the surveillance frequencies, originally proposed for relocation to the SFCP, do not meet any one of the four exclusion criteria defined in TSTF-425. Because of the format of Millstone's custom TS, the wording of some SRs seem to be conditional, but review concludes these surveillances are performed under normal operating conditions and are not associated with abnormal or degraded conditions. Therefore, relocation of SRs 4.4.6.2.1, 4.4.9.3, 4.6.3.2, 4.8.1.1.2, 4.8.2.1.d, 4.8.2.1 .e, 4.10.2.1.1, and 4.10.2.1.2 to the SFCP is consistent with TSTF-425.

However, the review also determined three SRs are not eligible for relocation to the SFCP. SR 4.7.1.2.1.b is controlled by the station's inservice testing program and therefore not eligible for relocation. SRs 4.7.5.b and 4.10.1.1 are associated with a specific condition and therefore are not eligible for relocation. New marked-up TS pages are provided in Attachment 2 for these SRs. The TS page for SR 4.10.1.1 is included and labeled "for Information only" to identify that no changes are being made to this page and it can be removed from the October 4, 2012 submittal.
