Identification of Spent Fuel Pool Water Levels Each unit at Vogtle Generating Plant its own fuel pool. spent fuel pools are within the Seismic Category 1 handling building. The pool is approximately 41 ft constructed of and lined with a 1/4-in. plate.
Contiguous to each spent fuel pool is a short canal to the transfer The transfer canal is connected to the canal inside the containment by the fuel tube. All movement spent fuel transfer are underwater, and the waterways are of depth to maintain a nominal 10 ft of shielding water above active fuel. A metal gate with gasket assembly the spent fuel the fuel transfer This allows transfer to without with the water level in fuel pool (see Attachment 1).
- 1. Level adequate to support operation of the normal fuel pool cooling system - Fuel pool level when suction loss occurs can be conservatively defined as SFP cooling low level set point 2 which is above the elevation at top of fuel pool cooling suction line that is at approximately 214'-11" (References 11, 14 through
- 2. Level adequate to provide substantial radiation shielding for a person standing on spent fuel pool operating deck - Elevation 1/8" is approximately _0" above 1/8", the point of fuel both Unit 1 and 2 (plus or minus 1 (Reference 10 - FSAR Section 9.1.2.2 figure 9.1.2-1 (Sh. 1 of 2) and References 11 & 12).
- 3. Level where fuel remains covered - Elevation 1/8/J is the nominal of the fuel rack 10 FSAR Section 9.1.2.2 and 9.1.2-1 (Sh. 1 of 2)

.. The will be continuous from top of the spent fuel racks at elevation 9.1.2-1 10f and KPTPrp
.. Instrument level sensing components (probe) will located in SFP directly adjacent to the fuel. The module will of located in a non-harsh environment area VEGP-1 & 2 RSFPI Integrated Plan 5 of 15 2/27/2013 12:21 PM
- The display shall provide a continuous indication of spent fuel pool water level at the Display location. In the event the link to the Display is lost, a field accessible signal/Indication (remote to the Display location) will be available for determination of pool level.
- The electronic processing module and the Display will be installed in a location that will meet the criteria established in NEI12 -02 and endorsed by NRC JLD-ISG-2012-03. The specific location of the electronic processing module and the Display has not been determined yet.
V. Reliability Reliability of the primary and backup instrument channels will be assured by conformance with the guidelines of NRC JLD-ISG-2012-03 or NE112-02, as discussed in Section 3.4, Qualification and 3.8 Testing. Reliable level indication will be functional during all times when used fuel is in the SFP cons istent with NEI 12-02 Section 4.3, Testing and Calibration .
VI. Instrument Channel Design Criteria Instrument channel design will meet the guidelines of NRC JLD-ISG-2012-03 and [\\EI12-02 and applicable sections of the plant FSAR with the exceptions and clarifications as detailed below.
A. Arrangement SFP level probes will be installed separate from each other in the SFP . Primary and backup level indication will be installed in the Main Control Room, at the alternate shutdown panel, or another appropriate and accessible location (reference NEI12-06) that complies with the NE112-02 following characteristics. SNC has not determined the exact location at this time and has several options that provide various benefits. For example, the Main Control Room is the NRC preferred location while an appropriate accessible location in the plant would provide information to personnel in the plant at a location closer to the pool and mitigation equipment. Both existing and new barriers will be used to provide a level of protection for the cable located on the refueling floor from falling debris missiles generated by the event.
Probes will consist of a small diameter stainless steel cable mounted within a protective sleeve (stilling well). The cable will end just above the fuel racks . Based on the light weight of the probe, it is assumed that the probe will survive the event with little or no damage . Likewise, the pool wall or spent fuel will not be damaged by any interaction with the protective sleeve during the event.
Specific channel level sensing components physical properties and installation details will be provided later after the engineering and design phase is completed.
The probe support (including stilling well) will be designed to shield the probe from event generated missiles (falling debris). The design of the probe and probe support will allow the fuel handling machine to pass over it without interference.
VEGP-1 & 2 RSFPI Integrated Plan Page 6 of 15 2/27/2013 12:21 PM
Cabling for power supplies and indications for each channel will be separated for missile protection (falling debris) and routed in separate conduits from cabling for the other channel.
B. Mounting Per NEI 12-02 Section 3.3, Mounting, the new equipment will be mounted to maintain the current Seismic Class of the Spent Fuel Pool which is Seismic Class I (Reference 13).
Thus, the new equipment will be seismically qualified to Class I. In addition, the mounting of the primary and backup channel components throughout the plant will meet the criteria of the structure it will be routed through or attached to. (refer to Qualification details below relating to cable and raceway installation criteria)
- c. Qualification The components/cables/connections for both primary and backup channels will be reliable at the temperature, humidity, and radiation levels consistent with the spent fuel pool water at saturation conditions for seven (7) days. Saturation temperature at the bottom of the SFP assuming normal water level will be approximately 250°F. Post event temperature at sensors located above the SFP is assumed to be 212°F. Post event humidity in the fuel pool floor near and above the SFP is assumed to be 100% with condensing steam. The components/cables/connections will be qualified for expected conditions at the installed location assuming the SFP has been at saturation for an extended period. The components/cables/connections located in the vicinity of the SFP will be qualified to withstand peak and total integrated dose radiation levels for their installed location assuming that post event SFP water level is equal to the top of irradiated fuel for a time no greater than six (6) hours. It is anticipated that the station personnel can align one of the three (3) SFP Cooling Strategies as detailed in NEI 12-06 if conditions are degrading as indicted by decreasing SFP level.
Conduit design in the SFP area will be installed to Seismic Category 1 criteria. Both existing and new barriers will be used to provide a level of protection for the cable located on the refueling floor from missiles. The existing and new raceway used to route the cable to the Display will be installed to Seismic Class 1 criteria. Augmented quality requirements, similar to those applied to fire protection, will be applied to the components installed in response to this Order.
The specific values to use for the shock and vibration qualification will be determined in the design phase of the implementation using FSAR and Design Basis information.
Components of the instrument channels installed in the SFP area will be qualified for shock and vibration using one or more of the following methods (note different methods may be used for the various sub components of the primary and back-Up instrument channels):

D. Independence The primary and backup instrument channels are of the same technology, are permanently installed, separated by distance or barriers, and utilize independent power supplies from different buses/switchgear.
E. Power Supplies Each channel will normally be powered from independent (different buses/switchgear) 120V AC power sources and will have a dedicated battery backup. The battery backup will be dedicated to each channel, should have the capability of automatically switching and operating on backup batteries and will have manual switching as a minimum. A minimum battery life of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> will be provided to allow for power restoration from portable equipment (refer to attachment 2 for a typical sketch). Refer to Safety Function Support section of the SNC Integrated Plan February 28,2013, submittal for NRC Order EA-12-049 for details on the power strategy from portable FLEX Diesel Generators (DGs) .
F. Accuracy Instrument channels will be designed such that they will maintain their design accuracy without recalibration following a power interruption or change in power source.
SNC plans for the instrument design accuracy to be within +/- 1 inch, or as close as reasonably achievable, over the entire range for the expected environmental and process conditions. Accuracy will consider SFP post event conditions, e.g., saturated water, steam environment, or concentrated borated water. Additionally, the instrument accuracy of the GWR technology will be sufficient to allow trained personnel to determine when the actual level exceeds the specified level of each indicating range (levels 1, 2 and 3) without conflicting or ambiguous indication. The accuracy will be within the resolution requirements of Figure 1 of NEI 12-02 .
G. Testing Instrument channel design will provide for routine testing and calibration consistent with Order EA-12-051 and the guidance in NEI 12-02.
- SNC plans for the design to facilitate in-situ testing and lor calibration of the Static or non-active installed (fixed) sensors
- SNC plans for the design to facilitate the microprocessor based channel features to be capable of testing while mounted in the pool.
- Existing work control processes will be used to control maintenance and testing.
(e.g., Preventive Maintenance (PM) Program, Surveillance Program, Vendor Contracts, or work orders)
- Other testing and calibration requirements are located in Program Controls testing sub section below.

H. Display Primary and backup indication will be provided in the Main Control Room, at the alternate shutdown panel, or another appropriate and accessible location (reference NEI12-06) that complies with the NE112-02 characteristics. If multiple display locations are powered from the instrument loop, then the guidance in NE112-02 regarding multiple displays will be followed (refer to attachment 2 for a typical sketch).
VII. Instrument Channel Program Criteria Instrument channel program criteria will be consistent with the guidelines of NRC JLD-ISG-2012 03 and NEI 12-02.
A. Training A systematic approach will be used to identify the population to be trained and to determine both the initial and continuing elements of the required training. Personnel will complete training prior to being assigned responsibilities associated with this instrument.
B. Procedures Procedures will be developed using guidelines and vendor instructions to address the maintenance, operation, and abnormal response issues associated with the new SFP instrumentation consistent with NEI12-02.
Procedures will address a strategy to ensure SFP water level addition is initiated at an appropriate time consistent with implementation of NEI12-06, Diverse and Flexible Coping Strategies (FLEX) Implementation Guide (References 5 and 7).
C. Testing and Calibration Processes will be established and maintained for scheduling and implementing necessary testing and calibration of the primary and backup spent fuel pool level instrument channels to maintain the instrument channels at the design accuracy.
Testing and calibration of the instrumentation will be consistent with vendor recommendations and any other documented basis. Calibration will be specific to the mounted instrument and the monitor. Out of service time as identified in NEI 12-02 will be incorporated consistent with the programmatic process used for compliance with NRC Order EA-12-049 (Order to Modify Licenses With Regard to Requirements for Mitigation Strategies for Beyond Design Basis External Events).
VIII. Need for Relief and Basis Southern Nuclear is not requesting relief from the requirements of Order EA-12-051 or the guidance in NE112-02 at this time, except as discussed herein.
Consistent with the requirements of Order EA-12-051 and the guidance in NE112-02 as endorsed by NRC JLD-ISG-2012-03, the six-month reports will delineate progress made, any VEGP-l & 2 RSFPI Integrated Plan Page 10 of 15 2/27/2013 12:21 PM
