1.0 DESCRIPTION
In accordance with the provisions of 10 CFR 50.90, Dominion Nuclear Connecticut, Inc.(DNC) submits a request for an amendment to the technical specifications (TSs) for Millstone Power Station Unit 2 (MPS2). The proposed amendment would modify TSs by relocating specific surveillance frequencies to a licensee-controlled program with the adoption of Technical Specification Task Force (TSTF)-425, Revision 3, "Relocate Surveillance Frequencies to Licensee Control -Risk Informed Technical Specification Task Force (RITSTF) Initiative 5b." Additionally, the change would add a new program, the Surveillance Frequency Control Program (SFCP), to TS Section 6, Administrative Controls.
The changes are consistent with NRC-approved Industry/TSTF Standard Technical Specifications (STS) change TSTF-425, Revision 3, (ADAMS Accession No.ML090850642).
The Federal Register notice published on July 6, 2009 (74 FR 31996), announced the availability of this TS improvement.
2.0 ASSESSMENT 2.1 Applicability of Published Safety Evaluation DNC has reviewed the safety evaluation provided in Federal Register Notice 74 FR 31996, dated July 6, 2009. This review included a review of the NRC staff's evaluation, TSTF-425, Revision 3, and the requirements specified in NEI 04-10, Rev. 1 (ADAMS Accession No. ML071360456).
Attachment 2 includes DNC documentation with regard to the technical adequacy of the probabilistic risk assessment (PRA) consistent with the requirements of Regulatory Guide (RG) 1.200, Revision 1 (ADAMS Accession No. ML070240001), Section 4.2.Attachment 2 also describes the PRA models without NRC-endorsed standards, including documentation of the quality characteristics of those models in accordance with RG 1.200.DNC has concluded that the justifications presented in the TSTF proposal and the safety evaluation prepared by the NRC staff are applicable to MPS2 and justify this amendment to incorporate the changes to the MPS2 TSs.2.2 Optional Changes and Variations The proposed amendment is consistent with the STS changes described in TSTF-425, Revision 3. However, DNC proposes variations or deviations from TSTF-425, as identified below.
Serial No.14-434 Docket No. 50-336 Attachment 1, Page 2 of 5 1. Revised (typed) TS pages are not included in this amendment request given the number of TS pages affected, the straightforward nature of the proposed changes, and outstanding MPS2 amendment requests that may impact some of the same TS pages. Providing only mark-ups of the proposed TS changes satisfies the requirements of 10 CFR 50.90 in that the mark-ups fully describe the changes desired. This represents an administrative deviation from the NRC staffs model application dated July 6, 2009 (74 FR 31996) with no impact on the NRC staffs model safety evaluation published in the same Federal Register notice. As a result of this deviation, the contents and numbering of the attachments for this amendment request differ from the attachments specified in the NRC staffs model application.
The proposed TS Bases changes are provided to the NRC for information only.2. The inserts provided in TSTF-425 are revised to fit the MPS2 TS format.The TSTF-425 insert for each relocated surveillance frequency is changed from "in accordance with the Surveillance Frequency Control Program to "at the frequency specified in the Surveillance Frequency Control Program." The insert provided in TSTF-425 to replace text describing the basis for each frequency relocated to the SFCP has been revised from "The Surveillance Frequency is based on operating experience, equipment reliability, and plant risk and is controlled under the Surveillance Frequency Control Program" to read"The(se) Surveillance Frequency(ies) is/are controlled under the Surveillance Frequency Control Program." This deviation is consistent with NRC guidance.
After NRC approval of the license amendment request (LAR) and as part of the LAR implementation, the existing MPS2 Bases information describing the basis for the relocated surveillance frequencies will also be relocated to a licensee-controlled program with the relocated surveillance frequencies.
In addition, other editorial changes to the existing TS wording and/or text inserts are being made. These administrative/editorial deviations of the TSTF-425 inserts and the existing TS wording are made to fit the MPS2 TS format.The approved programs for MPS2 are described in Section 6.0, "Administrative Controls," of the MPS2 TSs. The title descriptor in Table 4.7-2 (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 MPS2 TSs. To preclude future misunderstanding, DNC proposes to delete the word 'Program" from the title in Table 4.7-2. This change is reflected in the mark-up for Table 4.7-2 provided in Attachment 3.3. Attachment 4 provides a cross-reference between the NUREG-1432 surveillances included in TSTF-425 versus the MPS2 surveillances included in this amendment Serial No.14-434 Docket No. 50-336 Attachment 1, Page 3 of 5 request. Attachment 4 includes a summary description of the referenced TSTF-425 (NUREG-1432)/MPS2 TS surveillances which is provided for information purposes only and is not intended to be a verbatim description of the TS surveillances.
This cross reference highlights the following:
- a. NUREG-1432 surveillances included in TSTF-425 and corresponding MPS2 surveillances with plant-specific surveillance numbers, b. NUREG-1432 surveillances included in TSTF-425 that are not contained in the MPS2 TSs, and c. MPS2 plant-specific surveillances that are not contained in NUREG-1432 and, therefore, are not included in the TSTF-425 mark-ups.Since the MPS2 TSs are custom TSs, the applicable surveillance requirements and associated Bases numbers differ from the STSs presented in NUREG-1432 and TSTF-425, but with no impact on the NRC staffs model safety evaluation dated July 6, 2009 (74 FR 31996).For NUREG-1432 surveillances not contained in MPS2 TSs, the corresponding mark-ups included in TSTF-425 for these surveillances are not applicable to MPS2.This is an administrative deviation from TSTF-425 with no impact on the NRC staffs model safety evaluation dated July 6, 2009 (74 FR 31996).For MPS2 plant-specific surveillances not included in the NUREG-1432 markups provided in TSTF-425, DNC has determined that since these surveillances involve fixed periodic frequencies, relocation of these frequencies is consistent with TSTF-425, Revision 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.
In accordance with TSTF-425, changes to the frequencies for these surveillances would be controlled under the SFCP.There are several instances in the MPS2 TSs where the words 'and' and 'or' appear at the end of a surveillance requirement.
In most cases, these words are not intended to be logical connectors which place the constraints of the preceding surveillance requirement (often times event-driven) on the remaining portion of the surveillance but rather are used for purposes of readability and flow. This situation applies to the following SRs: 4.1.1.2, 4.1.3.1.1, 4.1.3.1.4b, 4.2.3.2b, 4.5.1d, 4.9.16 and 4.9.17.As currently written, SR 4.2.1.3b does not specify a surveillance frequency, however; it is performed at least once per 31 days, as required by its applicable station surveillance procedure.
As a result, the markup for this SR references the SFCP in accordance with TSTF-425.
Serial No.14-434 Docket No. 50-336 Attachment 1, Page 4 of 5 The SFCP provides the necessary administrative controls to require that surveillances related to testing, calibration, and inspection are conducted at a frequency to assure the necessary quality of systems and components is maintained, facility operation will be within safety limits, and the limiting conditions for operation will be met. Changes to frequencies in the SFCP would be evaluated using the methodology and PRA guidelines contained in NEI 04-10, Revision 1,"Risk-Informed Technical Specifications Initiative 5b, Risk-Informed Method for Control of Surveillance Frequencies" (ADAMS Accession No. ML071360456), as approved by NRC letter dated September 19, 2007 (ADAMS Accession No.ML072570267).
The NEI 04-10, Revision 1 methodology includes qualitative considerations, risk analyses, sensitivity studies and bounding analyses, as necessary, and recommended monitoring of the performance of structures, systems, and components (SSCs) for which frequencies are changed to assure that reduced testing does not adversely impact the SSCs. In addition, the NEI 04-10, Revision 1 methodology satisfies the five key safety principles specified in RG 1.177, "An Approach for Plant-Specific, Risk-Informed Decisionmaking:
Technical Specifications," dated August 1998, relative to changes in surveillance frequencies.
3.0 REGULATORY ANALYSIS 3.1 No Significant Hazards Consideration DNC has reviewed the proposed no significant hazards consideration (NSHC)determination published in the Federal Register dated July 6, 2009 (74 FR 31996).DNC has concluded that the proposed NSHC presented in the Federal Register notice is applicable to MPS2, and is provided as Attachment 5 to this amendment request, which satisfies the requirements of 10 CFR 50.91 (a).3.2 Applicable Regulatory Requirements A description of the proposed changes and their relationship to applicable regulatory requirements is provided in TSTF-425, Revision 3 and the NRC's model safety evaluation published in the Notice of Availability dated July 6, 2009 (74 FR 31996).DNC has concluded that the relationship of the proposed changes to the applicable regulatory requirements presented in the Federal Register notice is applicable to MPS2.3.3 Conclusions In conclusion, based on the considerations discussed above, (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
Serial No.14-434 Docket No. 50-336 Attachment 1, Page 5 of 5 4.0 ENVIRONMENTAL CONSIDERATION DNC has reviewed the environmental consideration included in the NRC staffs model safety evaluation published in the Federal Register on July 6, 2009 (74 FR 31996).DNC has concluded that the staffs findings presented therein are applicable to MPS2, and the determination is hereby incorporated by reference for this application.

Serial No.14-434 Docket No. 50-336 ATTACHMENT 2 Documentation of Probabilistic Risk Assessment (PRA)Technical Adequacy DOMINION NUCLEAR CONNECTICUT, INC.MILLSTONE POWER STATION UNIT 2 Serial No.14-434 Docket No. 50-336 Attachment 2, Page 1 of 14 Documentation of Probabilistic Risk Assessment (PRA)Technical Adequacy Quality of the PRA Regulatory Guide (RG) 1.200, "An Approach for Determining the Technical Adequacy of Probabilistic Risk Assessment Results for Risk-Informed Activities," provides the regulatory guidance for assessing the technical adequacy of a probabilistic risk assessment (PRA) model. Revision 2 of this RG (Reference
- 1) endorses (with comments and qualifications) the use of American Society of Mechanical Engineers (ASME)/American Nuclear Society (ANS) RA-Sa-2009, "Addenda to ASME RA-S-2008 Standard for Level 1/Large Early Release Frequency Probabilistic Risk Assessment for Nuclear Power Plant Applications," (Reference 2), NEI 00-02, "PRA Peer Review Process Guidelines," (Reference 3), and NEI 05-04, "Process for Performing Follow-On PRA Peer Reviews Using the ASME PRA Standard" (Reference 4). Revision 1 of this RG (Reference
- 5) had endorsed the internal events PRA standard ASME RA-Sb-2005,"Addenda to ASME RA-S-2002 Standard for Probabilistic Risk Assessment for Nuclear Power Plant Applications," (Reference 6). For the internal events PRA, there are no significant technical differences in the standard requirements between Revision 1 and Revision 2 of RG 1.200, and therefore assessments using the internal events standard of Revision 1 are acceptable.
To support approval and implementation of a Surveillance Frequency Control Program (SFCP) at Millstone Power Station Unit 2 (MPS2), Dominion Nuclear Connecticut, Inc.(DNC) evaluated the MPS2 PRA model using the guidance of RG 1.200 to ensure it is capable of determining the change in -risk due to changes to surveillance frequencies of systems, structures and components (SSCs), using plant-specific data and models.Capability Category II (CC II) of the standard is required by NEI 04-10 (Reference
- 7) for the internal events PRA. Any identified deficiencies to those requirements are further assessed to determine impacts to proposed changes to surveillance frequencies, including the use of sensitivity studies, where appropriate.
The MPS2 internal events PRA model received a formal industry peer review in 2000.The purpose of the PRA peer review process is to provide a method for establishing the technical quality of a PRA model for the spectrum of potential risk-informed plant licensing applications for which the PRA model may be used. The PRA peer review process used a team composed of industry PRA and system analysts, each with significant expertise in both PRA development and PRA applications.
This team.provided both an objective review of the PRA technical elements and a subjective assessment, based on their PRA experience, regarding the acceptability of the PRA elements.
The team used a set of checklists as a framework within which to evaluate the scope, comprehensiveness, completeness, and fidelity of the PRA products available.
The MPS2 review team used the "Combustion Engineering Owner's Group (CEOG) Peer Review Process Guidance" as the basis for the review. This review was Serial No.14-434 Docket No. 50-336 Attachment 2, Page 2 of 14 performed prior to issuance of an ASME PRA standard.
With the exception of one significance level B finding and observation (F&O), the significance level A and B F&Os from this peer review have been resolved.
NEI 05-04 characterizes only significance level A and B F&Os as "findings." In 2007, DNC performed a self-assessment of the MPS2 internal events PRA model using the ASME PRA standard, ASME RA-Sb-2005, and the guidance in RG 1.200, Revision 1. This self-assessment was re-performed in 2011 using the updated ASME PRA standard, ASME/ANS RA-Sa-2009.
Subsequently, in September 2012, Westinghouse completed a focused scope peer review of the upgraded PRA model of record, M209A, to evaluate its compliance with ASME/ANS RA-Sa-2009 and RG 1.200, Revision 2.Open items and findings resulting from the CEOG industry peer review, DNC's self-assessments, and the Westinghouse focused scope peer review, are provided in Table 1. These open items and findings represent the gaps between DNC's internal events PRA model and the PRA standard supporting requirements (SRs). For each gap, the table provides the ASME/ANS SR, Review Type and Issue Description, Disposition, and Impact to MPS2 PRA Model and Resolution.
Modeling gaps are classified as No Impact, Low Risk Significant, or Risk Significant to the application (based on their Fussell-Vesely (FV) importance value using a threshold value of 5E-3).The findings identified in the 2012 peer review and the significance level A and B F&Os identified in the 2000 peer review that have been resolved are available for review.PRA Model Maintenance and Update The MPS2 PRA model of record, M209Ac, and associated documentation have been maintained as a living program. The model is routinely updated approximately every 3 to 5 years to reflect the current plant configuration, additional plant operating history, and new component failure data. The M209Ac PRA model is highly detailed, including a wide variety of initiating events, modeled systems, operator actions, and common cause events. The PRA model quantification process used for the MPS2 PRA is based on the event tree/fault tree methodology, which is a well-known methodology in the industry.Dominion employs a structured approach to establishing and maintaining the technical adequacy and plant fidelity of the PRA models for the operating Dominion nuclear generating sites. This approach includes both a proceduralized PRA maintenance and update process, and the use of self-assessments and independent peer reviews. The following information describes this approach as it applies to the MPS2 PRA model.There are several procedures and GARDs (Guidance and Reference Documentation) that govern Dominion's PRA program. These documents define the process to Serial No.14-434 Docket No. 50-336 Attachment 2, Page 3 of 14 delineate the types of calculations to be performed, the computer codes and models used, and the process (or technique) by which each calculation is performed.
The NF-AA-PRA series of GARDs and procedures provide a detailed description of the methodology necessary to: " Perform PRA for the Dominion nuclear fleet, including Millstone, North Anna and Surry Power Stations" Create and maintain products to support licensing and plant operation concerns for the Dominion nuclear fleet* Provide PRA model configuration control* Create and maintain configuration risk evaluation tools for the Dominion nuclear fleet An administratively controlled process is used to maintain configuration control of the MPS2 PRA models, data, and software.
In addition to model control, administrative mechanisms are in place to assure that plant modifications, procedure changes, system operation changes, and industry operating experience (OE) are appropriately screened, dispositioned and scheduled for incorporation into the model in a timely manner. These processes help assure that the MPS2 PRA reflects the as-built, as-operated plant within the limitations of the PRA methodology.
The PRA model is periodically reviewed and updated to incorporate any changes in plant design or operation.
Plant modifications and procedure changes are reviewed periodically to determine if they impact PRA model and if any PRA modeling and/or documentation changes are warranted.
These reviews are documented, and if any PRA changes are potentially needed, they are added to the PRA Configuration Control (PRACC) database for PRA evaluation and implementation tracking.Scope of the PRA Each proposed change to a relocated surveillance frequency will be evaluated using the guidance contained in NEI 04-10 to determine its potential impact on risk, due to impacts from internal events, fires, seismic, other external events, and from shutdown conditions.
In cases where a PRA of sufficient scope or quantitative risk models are unavailable, either bounding analyses or other conservative quantitative evaluations will be performed.
A qualitative screening analysis may be used when the surveillance frequency impact on plant risk is shown to be negligible or zero.As noted above, MPS2 has an internal events PRA model which has received a peer review, self assessment, and a focused scope peer review, MPS2 does not have a PRA model for internal fire events or for external events. In accordance with NEI 04-10, Revision 1, the licensee will perform an initial qualitative screening analysis, and if the qualitative information is not sufficient, a bounding analysis will be performed.
The bounding analysis will be performed in accordance with NEI 04-10, Revision 1, Step Serial No.14-434 Docket No. 50-336 Attachment 2, Page 4 of 14 1Ob, and will be based on risk insights and analysis documented in the MPS2 Individual Plant Examination of External Events (IPEEE) report with consideration of the IPEEE accident sequences, as well as relevant OE and additional risk insights obtained since the IPEEE study, in the context of the current plant configuration and operation.
For shutdown events, a qualitative assessment of the changes in the surveillance frequencies will be performed using guidance from NEI 04-10, Revision 1.PRA Methodology The PRA methodology used at MPS2 includes a determination of whether a SSC affected by a proposed change to a surveillance frequency is modeled in the PRA model. Where a SSC is directly or implicitly modeled, a quantitative evaluation of the risk impact is performed.
The failure probability of the impacted SSCs, including the impact of the selected testing strategy (i.e., staggered or sequential testing) on common cause failure modes, is adjusted accordingly based on the proposed change to the surveillance frequency.
Where a SSC is not modeled in the PRA, bounding analyses are performed to characterize the impact of the proposed change to the surveillance frequency.
Potential impacts on the risk analyses due to screening criteria and truncation levels are addressed by sensitivity studies identified in NEI 04-10.Assumptions for Time Related Failure Contributions Failure probabilities of SSCs modeled in the PRA model may include both a standby time-related contribution and a cyclic demand-related contribution.
For SSCs affected by a proposed change to a surveillance frequency, NEI 04-10 guidance provides for adjustment of the time-related failure contribution.
This is consistent with RG 1.177, Section 2.3.3, which permits separation of the failure rate contributions into demand and standby for evaluation of surveillance frequency changes. If the available data does not support distinguishing between the time-related failures and demand failures, then the change to a surveillance frequency is conservatively assumed to impact the total failure probability of the SSC, including both standby and demand contributions.
The SSC failure rate (per unit time) is assumed to be unaffected by the change in test frequency and will be confirmed by the monitoring and feedback that is required after the surveillance frequency change is implemented.
The process requires consideration of qualitative sources of information with regards to the potential impact of surveillance frequency changes on SSC performance, including; industry and plant-specific OE, vendor recommendations, industry standards, and code-specified test intervals.
Therefore, the process is not reliant upon risk analyses as the sole basis for the proposed changes.The potential benefits of reduced surveillance frequency, which include reduced unavailability, less potential for restoration errors, reduced potential for test-caused Serial No.14-434 Docket No. 50-336 Attachment 2, Page 5 of 14 transients, and reduced test-caused wear of equipment, will be qualitatively assessed, but not quantitatively assessed.Sensitivity and Uncertainty Analyses In accordance with NEI 04-10, sensitivity studies will be performed to assess the impact of uncertainties from key assumptions of the PRA, uncertainty in the failure probabilities of the affected SSCs, impact on the frequency of initiating events, and any identified deviations from CC II of the PRA standard.
When the sensitivity analyses identify a potential impact on a proposed change, revised surveillance frequencies are considered along with any qualitative considerations that could impact the results of the sensitivity studies. Continued monitoring and feedback of SSC performance is required once a revised surveillance frequency is implemented.

This has the potential to have an impact on HFE quantifications.

I +/- 4 4 10 LE-C2, LE-C7 Finding F&O LE-C2-01 Focused Scope Peer Review: The MPS2 Severe Accident Mitigation Guidelines (SAMGs) were evaluated to determine what post-core damage operator actions might be credited.Of the 10 operator actions in the SAMGs, only two were found to be potentially applicable to post-core damage credit. Of these two operator actions, the HEP for the SGTR scenario was set to 1.0 based on timing concerns (time to perform vs.time available).
The other operator action for the containment isolation failure analysis was determined to be feasible but could not be located.Also, some implied operator actions in the containment isolation failure (1) For the SGTR scenario, the SAMG operator action to feed a dry steam generator for scrubbing of fission products has not yet been added to the MPS2 model.(2) The valves in the containment isolation analysis, identified as having implied operator actions, are associated with containment spray and safety injection.
These motor operated valves (MOVs), which are in series with check valves, do not get a containment isolation signal to close and, as such, should not have been credited in the containment isolation analysis.
These valves should be removed from the analysis and therefore, no HEP calculation is Impact: The impact of item 1 results in an insignificant decrease in LERF. The operator action to feed a dry steam generator for scrubbing of fission products needs to be realistically treated.The impact of item 2 results in an insignificant increase in LERF after the model is changed to remove the MOVs requiring manual action to close.Low Risk Significant Resolution:

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/TSTF Traveler, TSTF-425, Revision 3, "Relocate Surveillance Frequencies to Licensee Control-RITSTF Initiative 5b." 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 Millstone Power Station Unit 2 TS format.Basis for proposed no significant hazards consideration:
As required by 10 CFR 50.91 (a), DNC's 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.14-434 Docket No. 50-336 Attachment 5, 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, 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, DNC will perform a probabilistic risk evaluation using the guidance contained in NRC approved NEI 04-10, Rev. 1, in accordance with the Surveillance Frequency Control Program. 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, DNC concludes that the requested changes do not involve a significant hazards consideration as set forth in 10 CFR 50.92(c), Issuance of Amendment.

The CEA motion inhibit permits CEA motion within the requirements of LCO 3.1.3.6,"Regulating Control Element Assembly (CEA) Insertion Limits," and the CEA deviation circuit prevents regulating CEAs from being misaligned from other CEAs in the group. With the CEA motion inhibit inoperable, a time of 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> is allowed for restoring the CEA motion inhibit to OPERABLE status, or placing and maintaining the CEA drive switch in either the "off' or"manual" position, fully withdrawing all CEAs in group 7 to < 5% insertion.
Placing the CEA drive switch in the "off' or "manual" position ensures the CEAs will not move in response to Reactor Regulating System automatic motion commands.
Withdrawal of the CEAs to the positions required in the Required ACTION B.2 ensures that core perturbations in local burnup, peaking factors, and SHUTDOWN MARGIN will not be more adverse than the Conditions assumed in the safety analyses and LCO setpoint determination.
Required ACTION B.2 is modified by a Note indicating that performing this Required ACTION is not required when in conflict with Required ACTIONS A.1 or C. 1.Continued operation is not allowed in the case of more than one CEA misaligned from any other CEA in its group by > 20 steps, or one or more CEAs untrippable.
This is because these cases are indicative of a loss of SHUTDOWN MARGIN and power distribution changes, and a loss of safety function, respectively.
OPERABILITY of the CEA position indicators (Specification 3.1.3.3) is required to determine CEA positions and thereby ensure compliance with the CEA alignment and insertion limits and ensures proper operation of the CEA Motion Inhibit and CEA deviation block circuit.The CEA "Full In" and "Full Out" limit Position Indicator channels provide an additional independent means for determining the CEA positions when the CEAs are at either their fully inserted or fully withdrawn positions.
Therefore, the ACTION statements applicable to inoperable CEA position indicators permit continued operations when the positions of CEAs with inoperable position indicators can be verified by the "Full In" or "Full Out" limit Position Indicator channels.

nsert 2a The maximum CEA drop time permitted by Specification 3.1.3.4 is the assumed CEA drop time used in the accident analyses.
Measurement with Tavg > 515°F and with all reactor coolant pumps operating ensures that the measured drop times will be representative of insertion times experienced during a reactor trip at operating conditions.

25, 2003 POWER DISTRIBUTION LIMITS BASES by the ACTION statements since these additional restrictions provide adequate provisions to assure that the assumptions used in establishing the Linear Heat Rate, Thermal Margin/Low Pressure and Local Power Density -High LCOs and LSSS setpoints remain valid. An AZIMUTHAL POWER TILT > 0.10 is not expected and if it should occur, subsequent operation would be restricted to only those operations required to identify the cause of this unexpected tilt.Core power distribution is a concern any time the reactor is critical.
The Total Integrated Radial Peaking Factor -FTr LCO, however, is only applicable in MODE 1 above 20% of RATED THERMAL POWER. The reasons that this LCO is not applicable below 20% of RATED THERMAL POWER are: a. Data from the incore detectors are used for determining the measured radial peaking factors. Technical Specification 3.2.3 is not applicable below 20% of RATED THERMAL POWER because the accuracy of the neutron flux information from the incore detectors is not reliable at THERMAL POWER< 20% RATED THERMAL POWER.b. When core power is below 20% of RATED THERMAL POWER, the core is operating well below its thermal limits, and the Local Power Density (fuel pellet melting) and Thermal Margin/Low Pressure (DNB) trips are highly conservative.
The surveillance requirements for verifying that FTr and Tq are within their limits provide assurance that the actual values of FTr and Tq do not exceed the assumed values. Verifying FTr after each fuel loading prior to exceeding 70% of RATED THERMAL POWER rovides additional assurance that the core was properly loaded.3/4.2.6 DNB MARGIN Insert 2b The limitations provided in this specification ensure that the assumed margins to DNB are maintained.
The limiting values of the parameters in this specification are those assumed as the initial conditions in the accident and transient analyses; therefore, operation must be maintained within the specified limits for the accident and transient analyses to remain valid.MILLSTONE

The OPERABILITY of these systems is required to provide the overall reliability, redundance and diversity assumed available in the facility design for the protection and mitigation of accident and transient conditions.

Plant operation with an inoperable pressurizer high pressure reactor protection channel in the tripped condition is restricted because of the potential inadvertent opening of both pressurizer power operated relief valves (PORVs) if a second pressurizer high pressure reactor protection channel failed while the first channel was in the tripped condition.
This plant operating restriction is contained in the Technical Requirements Manual.The reactor trip switchgear consists of eight reactor trip circuit breakers, which are operated in four sets of two breakers (four channels).
Each of the four trip legs consists of two reactor trip circuit breakers in series. The two reactor trip circuit breakers within a trip leg are actuated by separate initiation circuits.
For example, if a breaker receives an open signal in trip leg A, an identical breaker in trip leg B will also receive an open signal. This arrangement ensures that power is interrupted to both Control Element Drive Mechanism buses, thus preventing a trip of only half of the control element assemblies (a half trip). Any one inoperable breaker in a channel will make the entire channel inoperable.
The surveillance requirements specified for these systems ensure that the overall system functional capability is maintained comparable to the original design standards.

ACTION Statement 8 applies to two inoperable automatic bypass removal channels.
If the bypass removal channels cannot be restored to OPERABLE status, the associated RPS channel may be considered OPERABLE only if the bypass is not in effect. Otherwise, the affected RPS channels must be declared inoperable, and the bypass either removed or the bypass removal channel repaired.
Also, ACTION Statement 8 provides for the restoration of the one affected automatic trip channel to OPERABLE status within the allowed outage time specified under ACTION Statement 2.ACTION Statements 7 and 8 contain the term "disable the bypass channel." Compliance with ACTION Statements 7 or 8 is met by placing or verifying the Zero Mode Bypass Switch(es) in"Off." No further action (i.e., key removal, periodic verification, etc.) is required.
These switches are administratively controlled via station procedures; therefore the requirements of ACTION Statements 7 and 8 are continuously met. periodically SR 4.3.1.1.2 and SR 4.3.2.1.2 specify a CHANNEL FUN TIONAL TEST of the bypass-Insert 2a function and automatic bypass removal once within 92 d s prior to each reactor startu The total bypass function shall be demonstrated OPERABLE at. least @nee on+during CHANNEL CALIBRATION testing of each channel affected by bypass operation.
he CHANNEL FUNCTIONAL TEST is similar to the CHANNEL FUNCTIONAL TESTS already required by SR 4.3.1.1.1 and SR 4.3.2.1.1, except the CHANNEL FUNCTIONAL TEST is applicable only to bypass functions and is performed once within 92 days prior to each startup.The MPS2 RPS is an analog system while the design of the MPS2 ESFAS includes both an analog portion and a digital portion. With respect to the analog portion of the systems, a successful test of the required contact(s) of a channel relay may be performed by the verification of the change of state of a single contact of the relay. This clarifies what is an acceptable CHANNEL FUNCTIONAL TEST of a relay. This is acceptable because all of the other required contacts of the relay are verified by other TS tests at least once per refueling interval with applicable extensions.
Proper operation of bypass permissives is critical during plant startup because the bypasses must be in place to allow startup operation and must be removed at the appropriate points during power ascent to enable certain reactor trips. Consequently, the appropriate time to verify bypass removal function OPERABILITY is just prior to startup. The allowance to conduct this test within 92 days of startup is based on the reliability analysis presented in topical report CEN-327, "RPS/ESFAS Extended Test Interval Evaluation," which is referenced in NUREG-1432 and is applicable to MPS2. Once the operating bypasses are removed, the bypasses must not fail in such a way that the associated trip function gets inadvertently bypassed.
This feature is verified by the trip function CHANNEL FUNCTIONAL TESTS SR 4.3.1.1.1 and SR 4.3.2.1.1.
Therefore, further testing of the bypass function after startup is unnecessary.

The ESFAS includes four sensor subsystems and two actuation subsystems for each of the functional units identified in Table 3.3-3. Each sensor subsystem includes measurement channels and bistable trip units. Each of the four sensor subsystem channels monitors redundant and independent process measurement channels.
Each sensor is monitored by at least one bistable.The bistable associated with each ESFAS Function will trip when the monitored variable exceeds the trip setpoint.
When tripped, the sensor subsystems provide outputs to the two actuation subsystems.
The two independent actuation subsystems each compare the four associated sensor subsystem outputs. If a trip occurs in two or more sensor subsystem channels, the two-out-of-four automatic actuation logic will initiate one train of ESFAS.

The primary to secondary LEAKAGEs determined using continuous process radiation monitors or radiochemical grab sampling i ccordance with the EPRI guidelines (Reference 5).BACKGROUND
[frequency specified in the Surveillance Frequency Control Program Components that contain or transport the coolant to or from the reactor core make up the reactor coolant system (RCS). Component joints are made by welding, bolting, rolling, or pressure loading, and valves isolate connecting systems from the RCS.During plant life, the joint and valve interfaces can produce varying amounts of reactor coolant LEAKAGE, through either normal operational wear or mechanical deterioration.
The purpose of the RCS Operational LEAKAGE LCO is to limit system operation in the presence of LEAKAGE from these sources to amounts that do not compromise safety. This LCO specifies the types and amounts of LEAKAGE.10 CFR 50, Appendix A, GDC 30 (Reference 1), requires means for detecting and, to the extent practical, identifying the source of reactor coolant LEAKAGE. Regulatory Guide 1.45 (Reference
- 2) describes acceptable methods for selecting leakage detection systems.The safety significance of RCS LEAKAGE varies widely depending on its source, rate, and duration.
Therefore, detecting and monitoring reactor coolant LEAKAGE into the containment area is necessary.
Quickly separating the IDENTIFIED LEAKAGE from the UNIDENTIFIED LEAKAGE is necessary to provide quantitative information to the operators, allowing them to take corrective action should a leak occur detrimental to the safety of the facility and the public.A limited amount of leakage inside containment is expected from auxiliary systems that cannot be made 100% leaktight.
Leakage from these systems should be detected, located, and isolated from the containment atmosphere, if possible, to not interfere with RCS LEAKAGE detection.
This LCO deals with protection of the reactor coolant pressure boundary (RCPB) from degradation and the core from inadequate cooling, in addition to preventing the accident analysis radiation release assumptions from being exceeded.
The consequences of violating this LCO include the possibility of a loss of coolant accident (LOCA).MILLSTONE

Surveillance Requirement 4.5.5.2 Testing must be performed to ensure the solubility and buffering ability of the TSP after exposure to the containment environment.
Passing this test verifies the TSP is active and provides assurance that the stored TSP will dissolve in borated water at postulated post-LOCA temperatures.
This test is performed by submerging a sample of 0.6662 +/- 0.0266 grams of TSP from one of the baskets in containment in 250 +/- 10 milliliters of water at a boron concentration of 2482 +/- 20 ppm, and a temperature of 77 +/- 5'F. Without agitation, the solution is allowed to stand for four hours. The liquid is then decanted, mixed, and the pH measured.
The pH must be > 7.0.The TSP sample weight is based on the minimum required TSP mass of 12,042 pounds, which at the manufactured density corresponds to the minimum volume of 223 ft 3 (The minimum Technical Specification requirement of 282 ft 3 is based on 223 ft 3 of TSP for boric acid neutralization and 59 ft 3 of TSP for neutralization of hydrochloric and nitric acids.), and the maximum sump water volume (at 77°F) following a LOCA of 2,046,441 liters, normalized to buffer a 250 +/- 10 milliliter sample. The boron concentration of the test water is representative of the maximum possible concentration in the sump following a LOCA. Agitation of the test solution is prohibited during TSP dissolution since an adequate standard for the agitation intensity cannot be specified.
The dissolution time of four hours is necessary to allow time for the dissolved TSP to naturally diffuse through the sample solution.
In the containment sump following a LOCA, rapid mixing will occur, significantly decreasing the actual amount of time before the required pH is achieved.
The solution is decanted after the four hour period to remove any undissolved TSP prior to mixing and pH measurement.
Mixing is necessary for proper operation of the pH instrument.

To be OPERABLE, the two trains of the containment spray system shall be capable of taking a suction from the refueling water storage tank on a containment spray actuation signal and automatically transferring suction to the containment sump on a sump recirculation actuation signal. Each containment spray train flow path from the containment sump shall be via an OPERABLE shutdown cooling heat exchanger.
The containment cooling system consists of two containment cooling trains. Each containment cooling train has two containment air recirculation and cooling units. For the purpose of applying the appropriate ACTION statement, the loss of a single containment air recirculation and cooling unit will make the respective containment cooling train inoperable.
Either the containment spray system or the containment cooling system is sufficient to mitigate a loss of coolant accident.
The containment spray system is more effective than the containment cooling system in reducing the temperature of superheated steam inside containment following a main steam line break. Because of this, the containment spray system is required to mitigate a main steam line break accident inside containment.
In addition, the containment spray system provides a mechanism for removing iodine from the containment atmosphere.
Therefore, at least one train of containment spray is required to be OPERABLE when pressurizer pressure is_> 1750 psia, and the allowed outage time for one train of containment spray reflects the dual function of containment spray for heat removal and iodine removal.Surveillance Requirement 4.6.2... 1 .a verifies the correct alignment for manual, power operated, and automatic valves in the Containment Spray System flow paths to provide assurance that the proper flow paths will exist for containment spray operation.
This surveillance does not apply to valves that are locked, sealed, or otherwise secured in position, since these valves were verified to be in the correct position prior to locking, sealing, or securing.
A valve that receives an actuation signal is allowed to be in a nonaccident position provided the valve automatically repositions within the proper stroke time. This surveillance does not require any testing or valve manipulation.
Rather, it involves verification that those valves capable of being mispositioned are in the correct position. 31 day freqtt-,y is appropriate b the... alve a ,perated MILLSTONE

Surveillance Requirement 4.6.2.1.1 .b, which addresses periodic surveillance testing of the containment spray pumps to detect gross degradation caused by impeller structural damage or other hydraulic component problems, is required by the ASME OM Code. This type of testing may be accomplished by measuring the pump developed head at only one point of the pump characteristic curve. This verifies both that the measured performance is within an acceptable tolerance of the original pump baseline performance and that the performance at the test flow is greater than or equal to the performance assumed in the unit safety analysis.
The surveillance requirements are specified in the Inservice Testing Program. The ASME OM Code provides the activities and frequencies necessary to satisfy the requirements.
Insert 2b Surveillance Requirements 4.6.2.1.1 .c and 4.6.2. 1.1 .d demonstrate that each a tomatic containment spray valve actuates to the required position on an actual or simulated a tuation signal (CSAS or SRAS), and that each containment spray pump starts on receipt of n actual or simulated actuation signal (CSAS). This surveillance is not required for valves th are locked, sealed, or otherwise secured in the required position under administrative controls.

Normal plant operation and maintenance activities are not expected to trigger performance of this surveillance requirement.
However, activities, such as an inadvertent spray actuation that causes fluid flow through the nozzles, a major configuration change, or a loss of foreign material control when working within the respective system boundary may require surveillance performance.
An evaluation, based on the specific situation, will determine the appropriate method (e.g., visual inspection, air or smoke flow test) to verify' no nozzle obstruction.
Surveillance Requirement 4.6-.2.1 2a demonstrates that each containment air recirculation and cooling unit can be operated in slow speed for > 15 minutes to ensure OPERABILITY and that all associated controls are functioning properly.

Any changes to this list will be reviewed under 1OCFR50.59 and approved by the committee(s) as described in the QAP Topical Report.The OPERABILITY of the containment isolation valves ensures that the containment atmosphere will be isolated from the outside environment in the event of a release of radioactive material to the containment atmosphere or pressurization of the containment.
Containment isolation within the time limits specified ensures that the release of radioactive material to the environment will be consistent with the assumptions used in the analyses for a LOCA.The containment isolation valves are used to close all fluid (liquid and gas) penetrations not required for operation of the engineered safety feature systems, to prevent the leakage of radioactive materials to the environment.
The fluid penetrations which may require isolation after an accident are categorized as Type P, 0, or N. The penetration types for each containment isolation valve are listed in FSAR Table 5.2-11, Containment Structure Isolation Valve Information.
Type P penetrations are lines that connect to the reactor coolant pressure boundary (Criterion 55 of 1OCFR50, Appendix A). These lines are provided with two containment isolation valves, one inside containment, and one outside containment.
Type 0 penetrations are lines that are open to the containment internal atmosphere (Criterion 56 of 1 OCFR50, Appendix A). These lines are provided with two containment isolation valves, one inside containment, and one outside containment.

Type N penetrations are lines that neither connect to the reactor coolant pressure boundary nor are open to the containment internal atmosphere, but do form a closed system within the containment structure (Criterion 57 of 1 OCFR50, Appendix A). These lines are provided with single containment isolation valves outside containment.
These valves are either remotely operated or locked closed manual valves.With one or more penetration flow paths with one containment isolation valve inoperable, the inoperable valve must be restored to OPERABLE status or the affected penetration flow path must be isolated.
The method of isolation must include the use of at least one isolation barrier that cannot be adversely affected by a single active failure. Isolation barriers that meet this criterion are a closed and de-activated automatic valve, a closed manual valve, and a blind flange. A check valve may not be used to isolate the affected penetration.
If the containment isolation valve on a closed system becomes inoperable, the remaining barrier is a closed system since a closed system is an acceptable alternative to an automatic valve.However, ACTIONS must still be taken to meet Technical Specification ACTION 3.6.3.1 .d and k-the valve, not normally considered as a containment isolation valve, and closest to the containment wall should be put into the closed position.
No leak testing of the alternate valve is necessary to satisfy the ACTION statement.
Placing the manual valve in the closed position , sufficiently deactivates the penetration for Technical Specification compliance.
Closed system isolation valves applicable to Technical Specification ACTION 3.6.3.1 .d are included in FSAR Table 5.2-11, and are the isolation valves for those penetrations credited as General Design Criteria 57, (Type N penetrations).

In the event the affected penetration is isolated in accordance with 3.6.3.1 .d, the affected penetration flow path must be verified to be isolated on a periodic basis, (Surveillance Requirement 4.6.1.1 .a). This is necessary to assure leak tightness of containment and that containment penetrations requiring isolation following an accident are isolate/ The freq, ,. of-on"- per 31 days in this srveillane, for v.ri. ying that eaeh affccWed fc1iltow path is isolated is eprpit onsiderirng the valves are aperated under admI atiVc nr an. tho probability eftheir misalignment is low.Insert 2a the purposes of meeting this LCO, neither the containment isolation valve, nor any alternate valve on a closed system have a leakage limit associated with valve OPERABILITY.

This requirement is necessary to meet the assumptions used in the accident analyses and limit the SITE BOUNDARY radiation doses to within the limits of 10 CFR 50.67 during LOCA conditions.
The laboratory testing requirement for the charcoal sample to have a removal efficiency of_ 95% is more conservative than the elemental and organic iodine removal efficiencies of 90%and 70%, respectively, assumed in the DBA analyses for the EBFS charcoal adsorbers in the Millstone Unit 2 Final Safety Analysis Report.

While the use of any supply side SW temperature indication is adequate to ensure compliance with the analysis assumptions, precision instruments installed at the inlet to the reactor building closed cooling water (RBCCW) heat exchangers will normally be used.Therefore, instrument uncertainty need not be factored into the surveillance acceptance criteria.All in-service instruments must be within the limit. If all of the precision instruments are out of service, alternative instruments that measure SW supply side temperature will be used. In this case, an appropriate instrument uncertainty will be subtracted from the acceptance criteria.Since Long Island Sound temperature changes relatively slowly and in a predictable fashion according to the tides, it is acceptable to monitor this temperature when there is ample (>5oF) margin to the limit.

A minimum run time of 60 minutes is required to stabili engine temperatures, while minimizing the time that the diesel generator is connected to the offsite source. Although no power factor requirements are established by this surveillance, th diesel generator is normally operated at a power factor between 0.8 lagging and 1.0. The 0.8 value is the design rating of the machine, while 1.0 is an operational limitation.
This surveillance is modified by five Notes. Note I indicates that diesel engine runs for Insert 2a this surveillance may include gradual loading, as recommended by the manufacturer, so that mechanical stress and wear on the diesel engine are minimized.

Recovery from the transient caused by the loss of a large load could cause diesel engine overspeed, which, if excessive, might result in a trip of the engine. This surveillance demonstrates the diesel generator load response characteristics and capability to reject the largest single load without exceeding a predetermined frequency limit. The single largest load for each diesel generator is identified in the FSAR (Tables 8.3-2 and 8.3-3).This surveillance may be accomplished by either: a. Tripping the diesel generator output breaker with the diesel generator carrying greater than or equal to its associated single largest post-accident load while paralleled to offsite power or while solely supplying the bus; or b. Tripping the equivalent of the single largest post-accident load with the diesel generator solely supplying the bus.The time, voltage, and frequency tolerances specified in this surveillance are based on the response during load sequence intervals.
The 2.2 seconds specified is equal to 40% of the 5.5 second load sequence interval associated with sequencing of the largest load (Safety Guide 9).The voltage and frequency specified are consistent with the design range of the equipment powered by the diesel generator.

In other circumstances, the grid voltage may be such that the diesel generator excitation levels needed to obtain a power factor of 0.9 may not cause unacceptable voltages on the emergency buses, but the excitation levels are in excess of those recommended for the diesel generator.
In such cases, the power factor shall be maintained as close as practicable to 0.9 lagging without exceeding the diesel generator excitation limits.SR 4.8.1.1.2.c.4 This surveillance demonstrates the diesel generator capability to reject a rated load without overspeed tripping.

This test simulates the loss of the total connected load that the diesel generator experiences following a rated load rejection and verifies that the diesel generator will not trip upon loss of the load. While the diesel generator is not expected to experience this transient during an event, this response ensures that the diesel generator is not degraded for future application, including reconnection to the bus if the trip initiator can be corrected or isolated.This surveillance is performed by tripping the diesel generator output breaker with the diesel generator carrying the required load while paralleled to offsite power.TIh 18 menth n.y is based an engineering judgment, taking into conside--;ratioon unit conad-itiefnls rcgquirced to per-fcrm:

This surveillance demonstrates the diesel generator operation during a loss of offsite power actuation test signal in conjunction with an ESF actuation signal, including shedding of the nonessential loads and energization of the emergency buses and respective loads from the diesel generator.
It further demonstrates the capability of the diesel generator to automatically achieve the required voltage and speed (frequency) within the specified time. The diesel generator auto-start time of 15 seconds is derived from requirements of the accident analysis to respond to a design basis large break LOCA. The surveillance should be continued for a minimum of 5 minutes in order to demonstrate that all starting transients have decayed and stability has been achieved.
The requirement to verify the connection of permanent and auto-connected loads is intended to satisfactorily show the relationship of these loads to the diesel generator loading logic. In certain circumstances, many of these loads cannot actually be connected or loaded without undue hardship or potential for undesired operation.
In lieu of actual demonstration of connection and loading of loads, testing that adequately shows the capability of the diesel generator system to perform these functions is acceptable.

SR 4.8.1.1.2.c.6 This surveillance demonstrates that diesel generator noncritical protective functions (e.g., high jacket water temperature) are bypassed on a loss of voltage signal concurrent with an ESF actuation test signal. During this time, the critical protective functions (engine overspeed, generator differential current, low lube oil pressure [2 out of 3 logic], and voltage restraint overcurrent) remain available to trip the diesel generator and/or output breaker to avert substantial damage to the diesel generator unit. An EDG Emergency Start Signal (Loss of Power signal or SIAS) bypasses the EDG mechanical trips in the EDG control circuit, except engine overspeed, and switches the low lube oil trip to a 2 of 3 coincidence.
The loss of power to the emergency bus, based on supply breaker position (A302, A304, and A505 for Bus 24C; A410, A41 1, and A505 for Bus 24D), bypasses the EDG electrical trips in the breaker control circuit except generator differential current and voltage restraint over current. The noncritical trips are bypassed during design basis accidents and provide an alarm on an abnormal engine condition.
This alarm provides the operator with sufficient time to react appropriately.
The diesel generator availability to mitigate the design basis accident is more critical than protecting the engine against minor problems that are not immediately detrimental to emergency operation of the diesel generator.

Surveillance Note 2 specifies that the start of the diesel generator from a standby condition is not required if this surveillance is performed in conjunction with SR 4.8.1.1.2.c.5.
Since this test is normally performed in conjunction with SR 4.8.1.1.2.c.5, the proposed note will exclude the requirement to start from a standby condition to minimize the time to perform this test. This will reduce shutdown risk since plant restoration, and subsequent equipment availability will occur sooner. In addition, it is not necessary to test the ability of the EDG to auto start from a standby condition for this test since that ability will have already been verified by SR 4.8.1.1.2.c.5, which will have just been performed if the note's exclusion is to be utilized.
If this test is to be performed by itself, the EDG is required to start from a standby condition.

The 5 minute period provides sufficient time to demonstrate stability.
Since the specified actuation signal (ESF signal without loss of offsite power) will not cause the emergency bus loads to be shed, and will not cause the diesel generator to load, the surveillance ensures that permanently connected loads and autoconnected loads remain energized from the offsite electrical power system (Unit 2 RSST or NSST, or Unit 3 RSST or NSST).

Postulated accident conditions which could cause an increase in spent fuel pool reactivity are: a single dropped or mis-loaded fuel assembly, a single dropped or mis-loaded Consolidated Fuel Storage Box, or a shielded cask drop onto the storage racks. A spent fuel pool soluble boron concentration of 1400 ppm is sufficient to ensure Keff < 0.95 under these postulated accident conditions.
The required spent fuel pool soluble boron concentration of > 1720 ppm conservatively bounds the required 1400 ppm. The ACTION statement ensure that if the soluble boron concentration falls below the required amount, that fuel movement or shielded cask movement is stopped, until the boron concentration is restored to within limits.An additional basis of this LCO is to establish 1720 ppm as the minimum spent fuel pool soluble boron concentration which is sufficient to ensure that the design basis value of 600 ppm soluble boron is not reached due to a postulated spent fuel pool boron dilution event. As part of the spent fuel pool criticality design, a spent fuel soluble boron concentration of 600 ppm is sufficient to ensure Keff < 0.95, provided all fuel is stored consistent with LCO requirements.
By maintaining the spent fuel pool soluble boron concentration
> 1720 ppm, sufficient time is provided to allow the operators to detect a boron dilution event, and terminate the event, prior to the spent fuel pool being diluted below 600 ppm. In the unlikely event that the spent fuel pool soluble boron concentration is decreased to 0 ppm, Keff will be maintained
<1.00, provided all fuel is stored consistent with LCO requirements.
The ACTION statement ensures that if the soluble boron concentration falls below the required amount, that immediate action is taken to restore the soluble boron concentration to within limits, and that fuel movement or shielded cask movement is stopped. Fuel movement and shielded cask movement is stopped to prevent the possibility of creating an accident condition at the same time that the minimum soluble boron is below limits for a potential boron dilution event./-periodic The surveillance of the spent fuel pool boron concentration within 24 ho s of fuel movement, consolidated fuel movement, or cask movement over the cask layotrea, verifies that the boron concentration is within limits just prior to the movement.
