- 1) for the Callaway Plant, documenting the diverse and flexible strategies (FLEX), in response to NRC Order Number EA-12-049 (Reference 2). This enclosure provides an update of milestone accomplishments since submittal of the OIP (Reference 1), including any changes to the compliance method, schedule, or need for relief/relaxation and the basis, if any. Refer to Section 8 of this enclosure for a list of References.
2 Milestone Accomplishments The following milestones have been completed since the development of the OIP (Reference 1 ), and are current as of July 31, 2013.
- PWROG has issued the NSSS-specific guidance
- ECA-0.0, Rev 2+, Loss of all AC Power
- Submittal of six-month status report for implementation of order EA-12-049 (this document) 3 Milestone Schedule Status The following table provides an update to Attachment 2 of the OIP (Reference 1). 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 do not impact the Order EA-12-049 (Reference
- 2) implementation date.

- 1. 4.1 Nitrogen Backup Capacity The Ameren Missouri FLEX response (Reference I) identified that Callaway Plant is designing a modification that will supplement the existing backup nitrogen capacity.
The concept was to provide sufficient nitrogen bottle capacity to provide nitrogen for 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> of operation.
In lieu of this modification, Ameren Missouri is revising its Phase I FLEX Strategy to provide a portable air compressor to supply the Atmospheric Relief Valves (ARVs) and the Turbine Driven Auxiliary Feedwater Pump (TDAFP) Flow Control Valves with compressed air. The installed nitrogen backup supply has sufficient capacity for approximately 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> of operation.
The portable air compressor is planned to be connected to test connections upstream of the nitrogen accumulator tanks that supply the back-up nitrogen to these valves. The portable air compressors will be powered from a Phase 2 portable generator.
4.2 NK Battery Load Shed The Ameren Missouri FLEX response (Reference I) indicated that after NK (Class IE I25-VDC) load shedding, only ARVs ABPVOOOI and ABPV0002 would have DC power available for operation and the Control Room would only be able to remotely control Auxiliary Feedwater (AFW) to Steam Generator (SG) A and D. The original strategy was to open the disconnects to Class IE I25 VDC Batteries NK13 and NKI4 to preserve these batteries until after Class IE I25-VDC Batteries NKII and NKI2 were depleted.
However, to preserve symmetrical cooldown Class IE I25-VDC Batteries NKI3 and NKI4 will be load shed except for the power to ARVs ABPV0003 and ABPV0004, as well as power to the TDAFP Flow Control Valves for SG Band SG D. Preliminary evaluation by Engineering indicates that this load is a low power draw from the batteries and would not cause a significant reduction in the amount oftime NK13 and NKI4 are able to supply I25-VDC power. 4.3 Storage/Protection of Equipment The Ameren Missouri FLEX response (Reference I) identified two locations for storage of Callaway Plant FLEX equipment.
Callaway Plant is evaluating the use of one (I) storage location meeting the requirements ofNEI I2-06, Sections 4 through 9. 4.4 Deployment of Phase 2 480 V AC Diesel Generators The Ameren Missouri FLEX response (Reference I) identified that FLEX connection panels would be installed in Corridor 130I of the Auxiliary Building 2000 elevation and the plant west wall of the Control Building.
Permanent sealed penetrations with grommets will be made in the walls of these buildings to provide access to the FLEX panels. Further evaluation has determined that it is not necessary to install the permanent sealed penetrations to the outside walls. In lieu of the wall penetrations, the cables from the Phase 2 portable 480-V AC diesel generators will be run through existing doorways.
Page 3 of6 Enclosure to ULNRC-06024 4.5 Deployment of Phase 3 4160 VAC Diesel Generators The Ameren Missouri FLEX response (Reference
- 1) identified that to facilitate connection of the generator cables to the Class 1E 4160-V AC switchgear, two new sealed penetrations will be installed in the west wall of the control building.
Further evaluation has determined that it is not necessary to install the permanent sealed penetrations to the outside walls. In lieu of the wall penetrations, the cables from the Phase 3 portable 4160-V AC diesel generators will be run through existing doorways.
5 Need for Relief/Relaxation and Basis for the Relief/Relaxation As described in Reference 1, Ameren Missouri is evaluating seismically qualifying the Condensate Storage Tank (CST) or installing a 670,000 gallon seismically qualified and missile protected CST. Ameren Missouri is evaluating the need for relaxation of Section N.A.2 of Order EA-12-049 regarding full implementation no later than two (2) refueling cycles after submittal of the OIP, so that the option to install a new seismically qualified and missile protected CST may be pursued. Refer to Open Item 5 in Section 6 below. If an extension is requested, the specific details will be provided to the NRC in a separate submittal.
The Ameren Missouri FLEX response (Reference
- 1) also stated that Ameren Missouri is crediting use of the RCP SHIELD Seal in our FLEX Strategies.
There is an industry identified issue, documented under 10CFR50 Part 21, with the current performance ofthis seal. The vendor (Westinghouse) has developed a plan to improve the RCP SHIELD Seal performance.
Ameren Missouri is evaluating the need for relaxation from the requirement of Section N.A.2 of Order EA-12-049 regarding full implementation no later than two (2) refueling cycles after submittal of the OIP, so that the option to credit the RCP SHIELD Seals may be pursued. The current required implementation date for Callaway Plant is the Fall 2014 refueling outage. An extension of one additional refueling cycle may be requested which would move the implementation date to the spring of 2016, still within the maximum allowed time frame of December 2016. The extension would provide additional time to resolve the RCP Seal performance issue and to fully design and safely implement modifications to the Callaway Plant. A new Open Item, OI8 has been created to track resolution of this issue and is included in Section 6 below. If an extension is requested, the specific details will be provided to the NRC in a separate submittal.
