This attachment provides an update of milestone accomplishments and open items since submittal of the OIP including any changes to the compliance 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 Plan 3 Milestone Schedule Status The following table provides an update to Attachment 2A of the Overall Integrated Plan. The table provides the activity status of each item, and whether the expected completion date has changed. The dates are planning dates subject to change as design and implementation details are developed.
The revised milestone target completion dates for 'Develop Strategies' and 'Unit 1 Outage Implementation' do not impact the Order implementation date.

4 Changes to Compliance Method By letter dated February 28, 2013, Dominion provided an Overall Integrated Plan (OIP) to address Beyond-Design-Basis (BDB) events at North Anna Power Station (North Anna) Units 1 and 2 (Reference 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 in the 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 - PWR Portable 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 of 2-SI-MOV-2890B (SI Train B). Figure 4 of the OIP still reflects the connection strategy for Unit 1, only the associated valve numbers that reflect the opposite SI train are different 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 for RCS injection for inventory and reactivity control has been moved from a Phase 3 activity to a Phase 2 activity. The details and descriptions provided in Section C.3 of the OIP for RCS injection for the Phase 3 activity continue to be the same for the Phase 2 strategy for RCS injection, including the time at which natural circulation capability is lost, 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 /> has been chosen, which provides significant margin (by a factor of 2) prior to loss of natural circulation and the start of reflux boiling.
Serial No. 12-162D Docket Nos. 50-338/339 Six Month Status Report - Order EA-12-049 Attachment Page 3 of 16 c) Details of the strategy for the portable diesel generators (DGs) used to re-power the 120VAC 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 per unit will be sized to accommodate the necessary electrical loads for that unit and will power both BDB distribution panels for that unit. Thus, the deployment of two 120/240VAC DGs per unit as shown in Figure 7 of the previously submitted OIP is no longer being pursued, and a revised Figure 7 is attached. Figure 8 is revised to show the location of the single 120/240VAC DG for each unit and the location of the associated unit's connection receptacles and is also attached. Figure 10 was a typical schematic of the connections from one of two 120/240VAC DGs. A revised Figure 10 showing the current connections for the 120/240VAC DG (Unit 1 only) is attached. A spare 120/240VAC DG will be purchased; however, as stated in the OIP, the 480VAC DG 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. Per Footnote 1 to Table 1, the quantities were based on the assumption that two storage buildings would be available to store BDB equipment pending completion of the study to determine the details of the BDB Storage Building(s). Open Item No. 6 has been completed, and the decision to have one storage building is documented in Section 6 of this update. A revised Table 1 is attached.
As discussed in the previous item b), North Anna will purchase and store BDB RCS Injection Pumps for use in the Phase 2 RCS Inventory strategy. These pumps are being 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 required relief/relaxation has been identified at this time.
