GINNA 6-MONTH STATUS REPORT (FEBRUARY 2014)
FOR RELIABLE SPENT FUEL POOL INSTRUMENTATION 1 Introduction The R. E. Ginna Nuclear Power Plant, LLC (Ginna) Overall Integrated Plan (OIP) was submitted to the Nuclear Regulatory Commission (NRC) in February 2013 (Reference 1), documenting the requirements to install reliable spent fuel pool level instrumentation (SFP LI), in response to Reference 2.
Subsequently, a supplement to the Ginna O1P for SFP LI was submitted to the NRC in March 2013 (Reference 3). In August 2013 the Ginna OIP for SFP LI, Revision 1, was submitted to the NRC as part of the Six-Month Status Report (Reference 4). By letter dated August 29, 2013 (Reference 5), the NRC requested that CENG respond to a request for additional information (RAI) regarding the Ginna OIP for Reliable Spent Fuel Pool Instrumentation. By letter dated September 23, 2013 (Reference 6), CENG responded to the August 29, 2013 RAI. By letter dated December 5, 2013 (Reference 7), the NRC provided Ginna with its Interim Staff Evaluation (ISE) and RAI regarding the OIP for Reliable Spent Fuel Pool Instrumentation.
This attachment provides an update of milestone accomplishments since submittal of the last six-month status report (Reference 4), including any changes to the compliance method, schedule, or need for relief/relaxation and associated basis (if applicable). Since the submittal of the last status report in August 2013, Ginna has completed the engineering and design phase and has begun the detailed planning work associated with installation of the SFP LI. Factory acceptance testing of both the primary and backup SFP LI channels, with the waveguides configured for installation at Ginna, has been successfully completed. No significant changes to the compliance methodology have occurred since the September, 2013 RAI response (Reference 6) was submitted.

Since the August 2013 Ginna OIP for SFP LI, Revision I (Reference 4), and the September 2013 SFP LI RAI response (Reference 6), the NRC provided Ginna with its ISE and RAI regarding the OIP for Reliable Spent Fuel Pool Instrumentation (Reference 7). Open items and regulatory commitments that were identified in References 4 and 6 have been completed or superseded by responses or a commitment made in this submittal to provide the information requested by the ISE RAIs issued in Reference 7.
Table 2 provides a list of open items and regulatory commitments from References 4 and 6 that have been completed or superseded by the responses or commitment made in this submittal. Table 3 provides a status of the ISE RAIs.
The following is the list of completed ISE RAI responses:
- 1. ISE RAI #1: Please provide additional information describing how the proposed arrangement of the waveguides and routing of the cabling between the radar horns and the electronics in the Intermediate Floor (Elevation 253 ft. 0 in.) meets the Order requirement to arrange the SFP level instrument channels in a manner that provides reasonable protection of the level indication function against missiles that may result from damage to the structure over the SFP.
This RAI response is complete. All equipment located in areas that are vulnerable to externally generated missiles (Auxiliary Building Operating Floor and SFP area) maintains physical channel separation of at least the width of the shortest side of the SFP. This provides for natural protection from a missile disabling both systems. Horn antenna and waveguide are mounted and routed at opposite sides of the SFP. The transmitter and conduit for its respective cabling that are located on the operating floor are also physically separated by at least the width of the shortest side of the SFP. Further, all cabling for each channel are routed in separate conduit and the transmitter and conduit for the southeast channel are located inside the new fuel storage building.

GINNA 6-MONTH STATUS REPORT (FEBRUARY 2014)
FOR RELIABLE SPENT FUEL POOL INSTRUMENTATION Equipment located in the Intermediate Floor of the Auxiliary Building is not vulnerable to externally generated missiles that may result from damage to the structure over the SFP as the concrete Auxiliary Building Operating Floor provides protection from missiles that may result from damage to the structure over the SFP.
- 2. ISE RAI #3: For each of the mounting attachments required to attach SFP Level equipment to plant structures, please describe the design inputs, and the methodology that will be used to qualify the structural integrity of the affected structures/ equipment.
This RAI response is complete. The sensor mount and the horn assembly mounts are qualified by calculation using the AISC 9th Edition design manual for steel construction. All anchorages are qualified using concrete anchor bolts and the manufacturer's design guide. The qualification of the anchorages is meant to be a demonstration of the feasibility of the chosen anchorage bolts and anchorage pattern. The final site anchorage is qualified using the site specific design guides.
The generic sensor calculation qualifies a simple C-channel steel section welded centrally on a 1/22 inch steel base plate. The base plate is anchored using four concrete anchor bolts. The generic sensor end support uses a generic seismic acceleration of lOg for the safe shutdown earthquake (SSE), which is meant to encompass the seismic response spectra of all the locations where these mounts are installed. The calculation assumes a maximum height of support to be 15 inches off of the wall. All mounts using a smaller length of C-channel are qualified by comparison.
Mounting of the SFP level transmitter wave guide at Ginna is addressed in calculation DA-ME-13-015., "Seismic Evaluation for SFP Level Indication Radar Guide Pipe and Supports" (Reference 9). Per Reference 9, piping shall be qualified as seismic category I in accordance with EWR 2512, "Design Criteria, Ginna Station Seismic Upgrade Program," (Reference 10) and the pipe supports shall be qualified to loading conditions which bound those specified in Reference
- 10. Protective steel is not credited for the seismic qualification of the wave guide pipe and shall be qualified for seismic 11/1 conditions.
ECP-13-000547, "Spent Fuel Pool Level Indication Modifications for Fukushima Response,"
(Reference 11) Form-015-7B-01 establishes installation criteria that all equipment installed at the SFP shall be mounted to retain its design configuration during and following the maximum seismic ground motion considered in the SFP structure (Mounting). All equipment installed shall not impact the operation of Seismic Category I equipment during or after a seismic event.
All equipment installed as part of this modification is qualified per IEEE 344-2004 (Reference
- 12) against the maximum seismic response spectra that envelopes the maximum seismic ground motion for the SSE. The Auxiliary and Standby Auxiliary Feedwater (SAFW) Buildings are Seismic Category I areas. All equipment is mounted as Seismic Class I or Class II/I. All electrical conduit supports are installed per GC-76.9, "Installation and Inspection of Electrical Equipment, Raceway and Electrical Supports," (Reference 13) per the standard Impell conduit support drawing series. The Control Panel mounting assembly will be mounted to unistrut using the hardware specified in drawing 02-9209819D (Reference 14).

FOR RELIABLE SPENT FUEL POOL INSTRUMENTATION
- 3. ISE RAI #4: Please provide analysis of the maximum expected radiological conditions (dose rate and total integrated dose) to which the equipment will be exposed. Also, please provide documentation indicating how it was determined that the electronics for this equipment are capable of withstanding a total integrated dose of Ix10 3 Rads. Please discuss the time period over which the analyzed total integrated dose was applied.
This RAI response is complete. Calculation Change Notice ECP-13-000547-CN-005, "Address Maximum Dose a SFP Level Transmitter for Fukushima Project," (Reference 15) calculates that the total integrated dose (TID) is 772 rad at the SFP level transmitter with the SFP level at the top of the racks for 7 days and that the bounding dose rate is 4 rad/hour. The calculation notes that this dose is very conservative as the level transmitter is not installed on the SFP deck, but rather is installed on the exterior surface of the SFP wall. With the additional shielding provided by the SFP wall, the TID would be significantly less.
AREVA Document No. 51-9202556, "Qualification Analysis of VEGAPULS 62 ER Through Air Radar," (Reference 16) states that the electronics for the SFP LI equipment must be located in an area that is shielded from the direct shine from the fuel, and bounce and scatter effects above the pool. For the purpose of this analysis, the radiation levels in the area do not exceed lxl03 rad.
NRC Bulletin 79-01B, "Environmental Qualification of Class IE Equipment," Table C-I, "Thermal and Radiation Aging Degradation of Selected Materials," (Reference 17) contains a listing of radiation thresholds for various materials. The most susceptible material, and therefore having the lowest threshold, was N-type metal oxide semiconductor (NMOS) electronics with a threshold of lx103 rad.
For current generation operating reactors, the staffs definition of a mild radiation environment for electronic components, such as semiconductors, or any electronic component containing organic materials as a total integrated dose of less than lxl03 rad (NUREG-1793 (Reference 18),
Chapter 3 Section 3.11.3.2.1).
This is further confirmed in Regulatory Guide 1.209 (Reference 19), Section B, which states "ionizing dose radiation hardness levels for MOS IC families range from about 10 gray (Gy) or 1 kilorad (krad) for commercial off-the-shelf (COTS) circuits to about 105 Gy (104 krad) for radiation hardened circuits."
Dose rates used for testing electronics using MIL-STD-883J, Method 1019.9 (Reference 20) are 50 rad/second or greater. The fact that this standard test does not test for dose rates lower than 50 rad/second, except as explained below, indicates that high dose rates that are lower than 50 rad/second are not a concern for electronic devices. At very low dose rates, some electronics that contain bipolar of BiCMOS or mixed-signal devices can be susceptible to Enhanced Low Dose Rate Sensitivity (ALDRS). For these devices MIL-STD-883J, Method 1019.9 also requires testing at low dose rate < 0.01 rad/second. However, it has been shown that at dose levels up to 104 rad there are no true dose rate effects. Therefore, at the total integrated dose estimated for the area where the electronics will be located, low dose rate sensitivity is not a concern.

FOR RELIABLE SPENT FUEL POOL INSTRUMENTATION
- 4. ISE RAI #7: Please provide information describing the evaluation of the comparative sensor design, the shock test method, test results, and forces applied to the sensor applicable to its successful tests, demonstrating the referenced previous testing provides an appropriate means to demonstrate reliability of the sensor under the effects of severe shock.
This ISE RAI is complete. Reference 16 documents that the VEGAPULS 62 ER through air radar sensor is similar in form, fit and function to the VEGAPULS 66 that was shock tested in accordance with MIL-S-901D (Reference 21). The test report is contained in AREVA Doc.
38-9193058 (Reference 22). Differences in construction are mainly in the smaller size of the VEGAPULS 62 ER. The shape of the housing, its material construction (precision cast stainless steel), the mass and form factor for the electronics modules, the materials and method for mounting the electronics into the sensor housing are the same between the VEGAPULS 66 and the VEGAPULS 62 ER. The incoupling and antennas for VEGAPULS 62 ER are smaller and lighter than for VEGAPULS 66 and therefore less susceptible to shock. Therefore, the shock testing is considered to be applicable to the VEGAPULS 62 ER sensor and the PLICSCOM indicator.
The MIL-S-90 ID test consisted of a total of nine (9) shock blows, three (3) through each of the three (3) principal axes of the sensor, delivered to the anvil plate of the shock machine. The heights of hammer drop for the shock blows in each axis were one (1) foot, three (3) feet and five (5) feet. The Level Indicator was energized and operating throughout the test. At the completion of each shock blow, in addition to visual inspection for evidence of physical damage and leakage, the Level Indicator was also checked for electrical malfunction. There was no apparent physical damage, leakage or electrical malfunction as a result of the shock blows.
In addition to the MIL-S-901D testing, the VEGAPULS 62 ER sensor has been shock tested in accordance with EN 60068-2-27 (Reference 23). (100g, 6 millisecond (ms)), ten (10) shock blows applied along a radial line through the support flange. Test results document that the requirements were fulfilled.
- 5. ISE RAI #8: Please provide information describing the evaluation of the comparative sensor design, the vibration test method, test results, and the forces and their frequency ranges and directions applied to the sensor applicable to its successful tests, demonstrating the referenced previous testing provides an appropriate means to demonstrate reliability of the sensor under the effects of high vibration.
This ISE RAI is complete. Reference 16 documents that the VEGAPULS 62 ER through air radar sensor is similar in form, fit and function to the VEGAPULS 66 that was vibration tested in accordance with MIL-STD-167-1 (Reference 24). The test report is contained in AREVA Doc.
38-9193058 (Reference 22). Differences in construction are mainly in the smaller size of the VEGAPULS 62 ER. The shape of the housing, its material construction (precision cast stainless steel), the mass and form factor for the electronics modules, the materials and method for mounting the electronics into the sensor housing are the same between the VEGAPULS 66 and the VEGAPULS 62 ER. The incoupling and antennas for VEGAPULS 62 ER are smaller and lighter than for VEGAPULS 66 and therefore less susceptible to vibration. Therefore, the vibration testing is considered to be applicable to the VEGAPULS 62 ER sensor and the PLICSCOM indicator.

GINNA 6-MONTH STATUS REPORT (FEBRUARY 2014)
FOR RELIABLE SPENT FUEL POOL INSTRUMENTATION The MIL-STD-167-1 vibration test procedure applies to equipment found on Navy ships with conventional shafted propeller propulsion. The test frequencies ranged from 4 Hz to 50 Hz with amplitudes ranging from 0.048" at the low frequencies to 0.006" at the higher frequencies. This procedure is not applicable to high-speed or surface effect ships that are subject to vibrations for high-speed wave slap, which produce vibration amplitudes and frequencies in excess of the levels on conventional Navy ships.
The potential vibration environment around the SFP and surrounding building structure might contain higher frequencies than were achieved in the testing discussed above. Additional testing of the VEGA PULS 62 ER sensor was performed in accordance with EN 60068-2-6 (Reference
- 25) Method 204 (except 5g, 500 Hz). Test results document that the testing requirement were met. This additional testing is considered to provide a stand-alone demonstration of the resistance to vibration of the VEGAPULS 62 ER sensor and further substantiates the results of the MIL STD-167-1 testing.
- 6. ISE RAI #9: Please provide information describing the evaluation of the comparative display panel ratings against postulated plant conditions. Also provide results of the manufacturer's shock and vibration test methods, test results, and the forces and their frequency ranges and directions applied to the display panel associated with its successful tests.
This RAI response is complete. The VEGADIS 61 and VEGADIS 62 displays feature housings that are similar in size, materials, and form factor to the VEGAPULS 62 ER sensor, contain a terminal base attached with two screws similar to the electronics module in the VEGAPULS 62 ER, and contain a LCD display module that installs into the housing similar to the PLICSCOM in the VEGAPULS 62 ER. Therefore, these devices are considered to have the same resistance to shock and vibration as the VEGAPULS 62 ER and PLICSCOM as described in the ISE RAI #7 and ISE RAI #8 responses above.
Evaluation of the comparative display panel ratings against postulated plant conditions by Ginna is performed as part of the Vendor Engineering Product Review per procedure CNG-CM-1.01-2003, "Acceptance of Vendor Engineering Products" (Reference 26). For example, AREVA Document No. 32-9208751, "AREVA Spent Fuel Pool Level Monitoring -
Horn and Transmitter Support," (Reference 27) was owner accepted and documents that "The accelerations used by AREVA are conservative and are higher than the evaluated accelerations at Ginna, with a Factor of Safety (FS) > 4.
- 7. ISE RAI #10: Please provide the results of seismic testing for shock and vibration effects to demonstrate the reliability of the components within the power and control panel under shock and vibration conditions.
This RAI response is complete. The components used in the power control panel are listed in the Table 4. Table 4 provides the shock and vibration test and/or analysis for each component.

FOR RELIABLE SPENT FUEL POOL INSTRUMENTATION Three components that were not shock or vibration tested by the manufacturers were included in a power control panel that was successfully seismically tested in accordance with the requirements of the IEEE Standard 344-2004 (Reference 12). The seismic test levels reached peaks of 19g in the x direction, 20g in the y direction, and 21 g in the z direction. The test response spectra exceeded IOg at all upper frequencies up to 100 Hz beyond which they were not recorded.
Also, these components are mounted to vibration dampeners to further minimize the transfer of external vibration to these components. There are no known reasons that would cause vibration to increase in an Extended Loss of All Power (ELAP) event.
- 8. ISE RAI #11: Please provide analysis of the seismic testing results and show that the instrument performance reliability, following exposure to simulated seismic conditions representative of the environment anticipated for the SFP structures at GNPP, has been adequately demonstrated.
This ISE RAI is complete. A VEGAPULS 62 seismic shake test was performed to the requirements of IEEE 344-2004 (Reference 12) for elements of the VEGAPULS 62 ER through air radar to levels anticipated to envelop most if not all plants in the United States. The equipment qualified included the VEGAPULS 62 ER sensor, PLICSCOM indicating and adjustment module, VEGADIS 62 display, Power Control Panel, rotatable horn waveguide assembly, waveguide piping including standard and repair flanges, and pool end and sensor end mounting brackets. The system was monitored for functionality before and after the resonance search and seismic tests. The required response spectra used for the five Operating Basis Earthquakes (OBEs) and one SSE in the test were taken from EPRI TR-107330 (Reference 29),
Figure 4-5.
In the test of the VEGAPULS 62 ER, the seismic required response spectra (RRS) used for the testing was in accordance with the RRS curve from EPRI TR-107330 (Reference 29) at 5%
damping (see Appendix D). This RRS is intended to envelop not only the seismic level for items mounted to building structure, but also the much higher levels that can be experienced for items mounted in or on cabinets due to the additional seismic amplification from cabinet resonances.
Evaluation of the seismic testing results by Ginna is performed as part of the Vendor Engineering Product Review per procedure CNG-CM-1.01-2003, "Acceptance of Vendor Engineering Products" (Reference 26). For example, AREVA Document No. 32-9208751, "AREVA Spent Fuel Pool Level Monitoring - Horn and Transmitter Support," (Reference 27) was owner accepted and documents that: "The accelerations used by AREVA are conservative and are higher than the evaluated accelerations at Ginna, with an [FS] > 4."
The waveguide piping between the horn end section and the sensor is supported by mounts provided and qualified by Ginna. The mounts provided by Ginna are not in the scope of AREVA Document No. 51-9202556 (Reference 16). The seismic test configuration had 10'-7 1/." between supports for the waveguide piping with standard flanges and 6'-31/2/2" between supports for the waveguide piping with repair flanges. These distances represent the maximum allowable distances between supports to maintain seismic qualification. Flanges were located both centrally between supports and near one support to test both conditions. Therefore, flanges may be located at any point between the supports.

GINNA 6-MONTH STATUS REPORT (FEBRUARY 2014)
FOR RELIABLE SPENT FUEL POOL INSTRUMENTATION Ginna Design Analysis DA-ME-13-015, "Seismic Evaluation of SFP Level Indication Radar System Guide Pipe and Supports," (Reference 9) documents that the SFP Level Indication piping is acceptable as designed for all sustained, occasional and thermal loading conditions and that the pipe supports are structurally adequate under all the loading combinations as specified within EWR 2512, "Design Criteria, Ginna Station Seismic Upgrade Program" (Reference 10).
DE-ME-13-015 Assumption 5.8 (Reference 9) documents that the Vendor has qualified their standard bolted flange design seismically to a maximum span of 10'-71/2/2". Ginna's proposed design includes a maximum span of 14'-l". This is acceptable based on the low stress levels calculated within this design analysis and the significant difference of the response spectra for the Ginna Auxiliary Building 315' elevation (5g peak) compared to the EPRI TR-107330 (Reference
- 29) response spectra (14g peak) used to qualify the waveguide components, a FS of 2.8.
Increasing the span by 33% is expected to increase the moment, and resulting stress levels, by a factor of 1.77, based on the beam equation for a uniform loading condition.
Additionally, an envelope of the response spectra for the 271' and 315' elevations in the Auxiliary Building is conservatively used. The response spectra for the 278' elevation is expected to be much closer to the 271' response spectra (1.2g peak, FS of 11.7), as the local ground elevation is 271' and SFP concrete structure extends from the 278' elevation down to bedrock. The significant increase in accelerations from the 271' to the 3 15' elevation is due to the transition of the structure from below grade concrete structure to above grade steel framed structure.
Additional support is provided by straps which are not credited for the seismic qualification will be installed on the protective steel structures at the transfer slot. Although not credited, these straps will provide additional support for the waveguide pipe.
A small portion of the 315' response spectra curve is greater than the curve of the generic EPRI spectra; however, this is at very low frequencies (< 2 Hz). Based on the models in DA-ME-1 3-015, Attachments B & C (Reference 9), the 1st mode of the actual configuration of the waveguide piping is outside of this range.
- 9. ISE RAI #12: Please provide the NRC staff with the final configuration of the power supply source for each channel so the staff may conclude the two channels are independent from a power supply assignment perspective.
This ISE RAI is complete. Each control panel will receive an independent non-safety related 120VAC power feed. Power for the northeast channel's control panel will be from ACPDPAF02 (located in the southeast corner of the SAFW building), circuit 8. This panel is fed from Motor Control Center (MCC) E, which is powered from Bus 15. Power for the southeast channel's control panel will be from the planned ACPDPAF05 panel located in the new Diesel Driven Auxiliary Feedwater (DDAFW) building. This panel will be fed from the Rochester Gas &
Electric (RG&E) 12 kilovolts (kV) Sodus Line or KDG08 (SAFW Beyond Design Basis Diesel Generator) through breaker 52Dl/SAFW as selected by automatic transfer switch 83/SAFW.
Each control panel also contains an internal battery backup that is independent from the station's alternating current (AC) and direct current (DC) distribution systems, which will ensure continued level indication on a Station Black scenario by powering the indication in the SAFW building and on the PLISCOM. Since the new DDAFW building will not be available during the Page 9 of 19

Once the new DDAFW building is completed, power for the southeast channel's control panel will be re-located.
- 10. ISE RAI #13: Please provide the results of the calculation depicting the battery backup duty cycle requirements, demonstrating battery capacity is sufficient to maintain the level indication function until offsite resource availability is reasonably assured.
This ISE RAI is complete. The Control panel contains eight Tadiran Model TL-5920 C-cell lithium batteries that provide backup power when normal 120VAC power is not available. The battery storage life is reported by the manufacturer to be up to 20 years. The battery life for worst case condition of 20 milliamps (mA) discharge rate is derived from the manufacturer technical data sheet. Examining the Capacity vs. Current curve for 20 mA discharge rate, it is seen that for
-30 0 C (-22 0 F), the lifetime is 2.7 Amp-hours (Ah), or 135 hours0.00156 days <br />0.0375 hours <br />2.232143e-4 weeks <br />5.13675e-5 months <br />. Because the chart considers discharge is when voltage drops from the nominal 3.6 volts down to 2.0 volts, a correction factor must be applied to determine lifetime to the point when voltage begins to significantly drop below nominal (considered to be below the full voltage point). The Discharge Characteristics @
25'C curve shows that at 20 mA discharge rate, discharge to 2 volts occurs at 6.8 Ah whereas the voltage starts to significantly drop at approximately 6.6 Ah, or 97% of total discharge. Applying this factor to the lifetime determined above, the corrected lifetime is 131 hours0.00152 days <br />0.0364 hours <br />2.166005e-4 weeks <br />4.98455e-5 months <br /> at -30'C. The lifetime increases significantly at lower discharge rates or at higher temperatures. Lifetimes at the temperatures for a 20 mA discharge rate are summarized in the Table 5.

These items are non-multiplying and, in general, are parasitic to the spent fuel rack local reactivity. Some of the items which fall under this category that can be safely stored in the spent fuel pool are: Dummy Canisters containing Non-SNM, Consolidation Hardware, Dummy Fuel Assemblies, Trash Basket containing full length control rods, etc. The general rule for safely storing these types of items is that any non-multiplying and non-fissile item can be safely stored in any cell location.
Any of these "other items" stored in the SFP will not contribute to a higher dose at the SFP operating floor greater than that bounded by the dose rate and integrated dose analysis as discussed in the ISE RAI #4 response above.
Procedure [P-OPS-6, "Control of Spent Fuel Pool Activities," (Reference 32) requires approval and tracking for all items entering the SFP water except the Tri Nuc equipment and filters, portable skimmer, fuel handling tools, RCCA tools, trash can lid tool, trash cans, Special Nuclear Material and Associate Components (SNMAC), temporary supplemental lighting and cameras, radiation protection underwater survey equipment. Information required includes reason for storage, location and method of storage, dose rate on contact and at 30 centimeters (cm), planned removal date and, if needed, any restrictions or compensatory actions to guard against inadvertent personnel exposure. If storage will be greater than 30 days from the initial SFP entry date, permission from the Operations Manager is required.
