1) documenting the diverseand flexible strategies (FLEX) for North Anna Power Station in response to NRC OrderNumber EA-12-049 (Reference 2). This attachment provides an update of milestone accomplishments and open items since submittal of the OIP including any changes to thecompliance method, schedule, or need for relief/relaxation and the basis, if any.2 Milestone Accomplishments The following milestone has been completed since the development of the Overall Integrated Plan, and is current as of July 31, 2013.0 Submit Integrated Plan3 Milestone Schedule StatusThe following table provides an update to Attachment 2A of the Overall Integrated Plan. Thetable provides the activity status of each item, and whether the expected completion date haschanged.

The dates are planning dates subject to change as design and implementation details are developed.

1) as required by Order Number EA-12-049, dated March 12, 2012(Reference 2). The following are changes to the compliance method information provided inthe North Anna OIP; however, the changes continue to meet NEI 12-06 (Reference 3):a) Details of the connection strategy for RCS injection, as described in Section C.3 -PWRPortable Equipment Phase 3, have changed for North Anna Unit 2 only. The installed tie-in location has been moved from a position downstream of motor-operated valve(MOV) 2-SI-MOV-2890A

[Safety Injection (SI) Train A] to a position downstream of2-SI-MOV-2890B (SI Train B). Figure 4 of the OIP still reflects the connection strategyfor Unit 1, only the associated valve numbers that reflect the opposite SI train aredifferent for Unit 2. Therefore, since the change does not impact the connection

strategy, OIP Figure 4 is not being revised.b) Changes to the timing of the RCS injection strategy have been made. The strategy forRCS injection for inventory and reactivity control has been moved from a Phase 3activity to a Phase 2 activity.

The details and descriptions provided in Section C.3 of theOIP for RCS injection for the Phase 3 activity continue to be the same for the Phase 2strategy for RCS injection, including the time at which natural circulation capability islost, i.e., approximately 33 hours3.819444e-4 days <br />0.00917 hours <br />5.456349e-5 weeks <br />1.25565e-5 months <br /> based on WCAP-17601 (Reference

5) and ETE-NAF-2012-0150 (Reference 7). For conservatism and margin to account for uncertainty within the calculations and unanticipated deployment issues, a time of 16 hours1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br /> hasbeen chosen, which provides significant margin (by a factor of 2) prior to loss of naturalcirculation and the start of reflux boiling.

Serial No. 12-162DDocket Nos. 50-338/339 Six Month Status Report -Order EA-12-049 Attachment Page 3 of 16c) Details of the strategy for the portable diesel generators (DGs) used to re-power the120VAC vital bus circuits, as described in Section F1.2 -PWR Portable Equipment Phase 2, have changed for North Anna Units 1 and 2. A single 120/240VAC DG perunit will be sized to accommodate the necessary electrical loads for that unit and willpower both BDB distribution panels for that unit. Thus, the deployment of two120/240VAC DGs per unit as shown in Figure 7 of the previously submitted OIP is nolonger being pursued, and a revised Figure 7 is attached.

Figure 8 is revised to showthe location of the single 120/240VAC DG for each unit and the location of theassociated unit's connection receptacles and is also attached.

Figure 10 was a typicalschematic of the connections from one of two 120/240VAC DGs. A revised Figure 10showing the current connections for the 120/240VAC DG (Unit 1 only) is attached.

Aspare 120/240VAC DG will be purchased;

however, as stated in the OIP, the 480VACDG is considered the alternate re-powering source for instrumentation.

d) The quantities of BDB equipment stated in OIP Table 1, PWR Portable Equipment Phase 2, and OIP Table 2, PWR Portable Equipment Phase 3, have changed.

PerFootnote 1 to Table 1, the quantities were based on the assumption that two storagebuildings would be available to store BDB equipment pending completion of the study todetermine the details of the BDB Storage Building(s).

Open Item No. 6 has beencompleted, and the decision to have one storage building is documented in Section 6 ofthis update. A revised Table 1 is attached.

As discussed in the previous item b), North Anna will purchase and store BDB RCSInjection Pumps for use in the Phase 2 RCS Inventory strategy.

These pumps arebeing added to the revised Table 1 for Phase 2 equipment.

5 Need for Relief/Relaxation and Basis for the Relief/Relaxation Dominion expects to comply with the Order implementation date and no requiredrelief/relaxation has been identified at this time.6 Open Items from Overall Integrated PlanThe following table provides a summary of the open items documented in Attachment 28 ofthe OIP and the status of each item.Overall Integrated Plan Open Item01 # Description StatusVerify response times listed in timeline and perform staffing Not started.1 assessment.
