NRC Request The Technical Specification (TS), Table 3.3.2.1-1 and associated TS Bases, define several separate "zones" of percent rated thermal power (%RTP) and minimum critical power ratio (MCPR), in which various trip functions are enabled or suppressed. The functional zones are defined by Conditions a, b, c and d. Condition e overlaps Conditions a, b and c. The associated TS Bases define "no-trip" zones (i.e., zones not requiring any trip function) at power levels below 30 percent for all MCPRs, at all power levels for MCPRs of 1.7 or greater, and at power levels above 90% for MCPR greater than or equal to 1.4. The proposed Allowable Values (AVs) protect against errors in determining which zone is in effect at any given time. The margin applied to the 30 percent limit ensures that an underestimation of thermal power when operating just above 30 percent will tend to result in the application of the Condition a setpoints rather than in the assumption of "low power no-trip" zone and the suppression of all trips. This is clearly conservative. But it is not clear whether Condition a setpoints or Condition b setpoints are more conservative for thermal power estimation errors when operating near 65 percent. Similarly, for Condition b and c near 85 percent. The inverse relationship of setpoint to power regime further confuses this matter (the low power trip setpoints are higher than the high power trip setpoints). In addition, the "high power no-trip" zone for power greater than or equal to 90 percent with MCPR greater than or equal to 1.4 seems to indicate, counter intuitively, that operation is safer above 90 percent than below 90 percent.
For all RBM Functions in TS Table 3.3.2.1-1 and for the "no-trip" zones in the TS Bases for the RBM (B3.3.2.1, page B3.3-45), please indicate whether overestimation or underestimation of thermal power is more conservative and provide the reasoning behind each determination. Show that the proposed margins are on the correct side (i.e., where the margins produce, rather than detract from, conservatism) of each zone boundary.
Explain why no margin is needed at the 90 percent power level.

~rg NLS2004006 Attachment I Page 2 of 10 NPPD Response:
Please refer to the graph on the following page along with the following explanation. The way that the setpoints for the various regions were determined has not changed from when Cooper converted from flow-biased RBM setpoints to the current three zone method. Instrument uncertainties are deducted from thle Analytical Limit (AL) to determnine the Allowable Value (AV) and Nominal Trip Setpoint (NTSP), per GE Setpoint Methodology. Additional tests are then applied to the NTSP (i.e. LER Avoidance, Required Limits Evaluation) and a final operating setpoint determnined. In the case for the transition from the 'No Rod Block Required' region less than 30% RTP to the loy power (LP) region, the conservative situation is to have the rod block in effect prior to reaching 30%, so the calculated AV is 27.5% and the setpoint is 26%. As mentioned, clearly this is conservative. For the transition from the low power setpoint (LPSP) to the intermediate power setpoint (IPSP) and the IPSP to high power setpoint (HPSP), the same calculational methodology was used, i.e. deducted instrument uncertainties from the AL to determline the AV and NTSP. In those two cases, it is conservative to have the transition region below the AL (and also below the AV) and use the rod block setpoint of the "higher region." Specifically, when moving from the LP region to the IP region, the rod block setpoint will shift from 118% down to 113% at 61% RTP, even though the rod block setpoint could be 118% up to the AV of 62.5% RTP. The same discussion holds for the transition from the IP region to the HP region. Additionally, an underestimation of thermal power when operating just above the AL will still result in a shift to the next higher region's rod block setpoint before reaching the AL, while an overestimation of thermal power will cause a shift to the next higher region at some point below the AL, both of which are more limiting.
The calculation Conclusion Section lists a set of permissible rod block values for AL, AV and Operating Setpoint, based on different MCPR Limits. From USAR Section XIV-7, Table XIV-7-2, the MCPR Limit for Rod Withdrawal Error for the current fuel cycle is 1.32. Therefore, the setpoints; for the various regions were selected based on a MCPR Limit of 1.30, which yields the lower rod block setpoints.
The proposed change to the "algebraic signs" in SR 3.3.2.1.4 and Table 3.3.2. 1-1 (Notes) is based on our determination that it is conservative to ensure that the rod block setpoint for the next higher region is in effect prior to the AL because that rod block setpoint is a lower value, and thus more limiting.
Even though the Rod Block Monitor function is not required above 90% when MCPR is greater than 1.4, there is no bypass for this region. The only conditions that will automatically bypass the RBM is operation below the Low Power Setpoint (analytical limit of 30%RTP) or a peripheral control rod selected for movement. Therefore, there is

NRC Request If the estimated MCPR were above 1.7, but the actual MCPR were less than 1.7, then Functions la, lb, Ic and le would be suppressed when in fact they should be active. This would be a non-conservative condition. A similar situation exists for the MCPR limit of 1.4 for power levels of 90 percent and above, associated with Function Id. Please explain how this condition is to be avoided, given that the proposed TS changes do not include the addition of margin to the MCPR limits.
NPPD Response The question implies that the system is not in-service during periods when the MCPR is
Michelle Honchank - 20)U4(U.wrpP ae above 1.7. However, this is not the case. The system is in' service whenever the reference power level is above the Low Power Setpoint, regardless of the calculated MCPR.

NRC Request The mark-up for pages B3.3-45 of the TS Bases shows the 30 percent limit changed to 27.5 percent. The description in the TS Bases should show the objectives of the TS settings, not necessarily the TS settings themselves. The TS value is proposed to be changed from 30 percent to 27.5 percent to ensure that the power-related adjustment in trip setpoint does indeed occur at or below 30 percent despite anticipated uncertainty in the power estimation. As far as the bases are concerned, the objective is to establish a limit at 30 percent. It would seem the TS Bases should not be changed here. Please explain the proposed change.
NPPD Response CNS agrees with the comment. The 30 % number will be retained in TS Bases. The bases is discussing the results of an analysis which has a bases value of 30%. We are adjusting the setpoint and allowable value to address instrumentation uncertainty.

NRC Request Please show that the margin between each proposed AV and the corresponding Analytical Limit (AL) is adequate to include all uncertainties remaining in the instrument sensor and channel following calibration. Confirm that the AVs are not affected by the "LER Avoidance Evaluation" or by any other setpoint adjustment based upon operational considerations.
NLS2004006 Attachment I Page 5 of 10 NPPD Response By the definition of GE Setpoint Methodology (NEDC-31336P-A, General Electric Instrument Setpoint Methodology), the margin between the AV and AL is a statistical combination of all uncertainties identified except instrument drift. The margin between AL and the NTSP is the statistical combination of all uncertainties identified. The LER Avoidance Evaluation is an adjustment (if necessary) of the trip setpoint (NTSP) away from the AV to assure that there is sufficient margin to avoid violating the AV during surveillance testing. Likewise, any other setpoint adjustments based on operational considerations would be away from the AV to provide additional margin.

NRC Request
Michelle Honchank - 2UU4UUb.wpa l-ae vage ts I Calculation Section 2.2: The units for the RBM Trip Function AL's are not specified. We presume these to be % RTP. The units for the AL's for the various Trip Setpoints (SP's) are also not specified. Since the Low Trip SP values are higher than the High Trip SP values, these cannot be % RTP. Since they are above 100 percent, they cannot be %
Calibrated Span. Please describe the units and scaling, and provide a brief explanation as to how the associated trip signals are derived. For example: Is there a separate comparator for each of the three neutron monitors, with one of the three comparators enabled on the basis of power level? Is there just one comparator with analog input selected from among the three neutron monitors on the basis of power level?
NPPD Response The preset limits vary with power. The system monitors local thermal power by generating a signal from the Local Power Range Monitors (LPRM) in the detector assemblies which surround the rod selected for movement. The system receives a "rod select" signal from Reactor Manual Control System (RMCS).
It routes the LPRM outputs from the LPRM assemblies adjacent to the selected rod to the averaging circuit. The system adjusts the averaged signal to equal a constant reference signal. The gain change circuit increases the gain of the averaged signal until its output equals, or exceeds, the constant reference signal. The system then compares this signal to a power-biased trip setpoint. This power biased trip setpoint has three different values.
The value used is based on the Average Power Range Monitor (APRM) Reference channel power. A rod withdrawal block is generated if the normalized LPRM signal rises above the power-biased trip setpoint. On the selection of a rod, the control circuitry controls the sequence of events which prepares the RBM system for proper operation.
This sequence of events is called the "Nulling Sequence".
NLS2004006 Page 6 of 10 Low power setpoint (LPSP) provides the reference for the RBM auto bypass (30% of rated power). Below LPSP the RBM is bypassed.
Intermediate power setpoint (IPSP) provides a fixed reference of 65% rated power.
Between LPSP and lPSP, the Low Trip Setpoint is in effect.
High power setpoint (HPSP) provides a fixed reference of 85% rated power. Between IPSP and HPSP, the Intermediate Trip Setpoint is in effect. Above HPSP the High Trip Setpoint is in effect.
These setpoints provide a reference for rod block signals. Each time power level increases (on the reference APRMs) the RBM setpoints automatically change to a lower trip setpoint as discussed below.
Low Trip Setpoint (LTSP):

When power level is below 65% (below IPSP), the rod block trip setpoint is <
120%.
Intermediate Trip Setpoint (ITSP):
When power level is above 65% but below 85%, the rod block trip setpoint is automatically changed to < 115%.
High Trip Setpoint (HTSP):
When power level is above 85%, the rod block trip setpoint changes to < 110.5%.
The units for the "power setpoints" (LPSP, IPSP, HPSP) are a reference input from an APRM channel, and are in units of percent of rated thermal power (%RTP).
The units for the "trip setpoints" (LTSP, ITSP, HTSP) are the indicated value based on a full scale of 125. Therefore, the units are divisions of full scale.

NRC Request Calculation Section 2.2 note "**": The TSs show the limit as 90 percent, not 89 percent.
Please explain.
NLS2004006 Attachment I Page 7 of 10 NPPD Response The 90% listed to in TS Table 3.3.2. 1-1 notes c, d and e refer to a change in the operating region for the Rod Block Monitor. However, the RBM does not actually change operation at this point, it continues to function as it did below 90%. The note is referring to the Downscale Trip Setpoint (DTSP) with an analytical limit of 89%. The DTSP will generate a control rod block if the selected RBM channel power is too low from its most recent normalized calibration conditions. This assures that the normalization performed at the time of rod selection remains valid before permitting withdrawal of the rod.
Therefore, the 90% value listed in the TS table notes is not the same thing as the 89%
DTSP.

NRC Reguest Calculation Section 2.2 note "**": There appears to be missing text between the final two lines. Please clarify.
Michelle Honcharik - 2004006.wpd._age1u n
NPPD Response The last sentence of the note "The DTSP limit is not utilized in any licensing bases Rod Withdrawal Error (RWE) analysis or that the range is restricted by design to values considered in the RWE analysis." is a combination of statements from two GE documents. The first ones states "Also, the DTSP limit is not utilized in any of the licensing basis RWE analyses." as part of the justification for changing the Analytical Limit from 91% to 89%. The second one defines 'no limitations' in a table which gives trip level settings for the various RBM functions, but does not list a value for DTSP other than N/L; "N/L - no limitations; means either that the setpoint does not affect the RWE analysis or that the range is restricted by design to values considered in the RWE analysis." The last half of the sentence does not add to the discussion and may be deleted in a future revision.
- 8.
NRC Request Calculation Section 2.2 note "***": TS Table 3.3.2.1-1 Function le, Condition e, indicates that an MCPR limit (less than 1.7) does apply to the Downscale Trip Setpoint.
Please resolve this apparent conflict between the calculation and TS.
NPPD Response Condition e associated with function le refers to the plant operating conditions when the downscale function is required. The MCPR Limits listed in Section 2.2 of the calculation show what the AL should be to protect the fuel during a rod withdrawal accident.

NRC Request Assumption 3.2: Please justify the claim that seismic effects are insignificant. Note that the zero period acceleration (ZPA) is a property of the mounting location, not of the device itself; and must be at least equal to the floor ZPA, which is likely greater than the ground ZPA. It is not clear that this is an inconsequential value.
NPPD Response GE document NEDC-31336P-A, General Electric Instrument Setpoint Methodology, sections 3.19 and 3.20 provide guidance for assumptions for the RBM and APRM.
Neither section discusses seismic effect. Additionally, the prior setpoint calculation for the APRM and RBM was performed by GE, and included an assumption that stated "GE APRM/RBM equipment accuracy specification includes the uncertainties due to seismic effect on the equipment located in the relay room panels. The panels are qualified as a unit." Therefore, seismic effect is not included as a separate item in the setpoint

- 10.
NRC Request Calculation Assumption 3.3: Uncertainties are usually two-sigma values. The assumption that the standard deviation is only 1/3 - rather than z - of the uncertainty seems non-conservative. This is especially true since the accuracy of the calibration standard is assumed to be only as good as the test equipment that it is used to calibrate. In addition, it is not clear how the fact that "100 percent testing" is implemented relates to the question of whether the associated uncertainties are two-sigma or three-sigma values.
Please clarify and justify Assumption 3.3.
NPPD Response The assumption that individual calibration accuracy terms are three-sigma values is from a CNS specific, GE setpoint guidance document This document also uses the term controlled by 100% testing to signify that the calibration tests performed on both the instrument itself and all of the calibration standards are actual performance results and not sample results that are statistically applied to a batch of instruments or standards.
Additionally, by assuming that the calibration standard's uncertainty is equal to the calibration tool's uncertainty, NPPD is adding additional conservatism to the determination of the Allowable Value.
- 11.
NRC Request Calculation Assumption 3.9: The important quantity is the expected variation in current with the design basis variation in voltage, not necessarily just a 1 percent variation in voltage. Is this effect not already addressed in the overall accuracy specification for the detection system?
NLS2004006 Page 9 of 10 NPPD Response: Yes, it is addressed. Per GE document NEDC-31336P-A, General Electric Instrument Setpoint Methodology, sections 3.20 and 4.5, the sensor accuracy is included.
- 12.
NRC Request Calculation Assumption 3.11: This addresses a fundamental design issue that seems too important to be covered in an assumption, and it begs the question of why such an assumption should be required. Is the installed equipment the same as that originally provided by General Electric or not? If it is not actually the same equipment, in what sense is it "the same?" Why is the calculation not simply based explicitly upon the actually-installed equipment?
NPPD Response The equipment installed is the same as originally provided by General Electric.
Michelle Honcharik - 2004006.wpd q.~.-
Page 1.2 I
- 13.
NRC Reguest Calculation Assumption 3.14: Please show that the temperature and humidity effects are negligible, based upon the design conditions at the equipment locations and upon the anticipated limiting effects of temperature and humidity upon the equipment.
NPPD Response GE document NTEDC-31336P-A, General Electric Instntment Setpoint Methzodology, sections 3.19 and 3.20 provide guidance for the environmental effects assumptions for the RBM and APRM. For the RBM, "There will not be an environmental effect during the RWE (Rod Withdrawal Error) transient before the rod block function is completed."
Similar wording is provided for the APRM in section 3.20, "There will not be an environmental effect during the Design Basis Events before the scram function is complete. Therefore, the harsh environment effect is not applicable." Therefore, temperature and humidity effects do not need to be considered.
- 14.
NRC Request Calculation Assumption 3.16: Flow element uncertainty would normally be expressed in terms of the uncertainty in the differential pressure produced for a given flow rate. The actual flow measurement uncertainty includes uncertainty in the measurement of that differential pressure as well as in the behavior of the venturi itself. Please confirm that the assumed 2 percent uncertainty is the composite flow measurement channel uncertainty, not just the element uncertainty. Please explain how the uncertainty in this specific application is known to be bounded by the analyses in the referenced documents.
NLS2004006 Page 10 of 10 NPPD Response The venturi uncertainty is 2% of flow based on the design specification. However, the overall flow loop uncertainty is 2.965% of flow as determined in the first half of Step 4 on page 15 of 64. This value is then 'converted' in the second half of Step 4 to an equivalent power level of 1.957%. Additionally, the factory test report results for the flow venturi's states "the average flow rate for each run should be within -- 0.25% of the true value" which indicates that the flow uncertainty assumed in the calculation is conservative.
- 15.
NRC Request Calculation Assumption 3.18: Please clarify. The uncertainty in the output of the summer would be equal to the combination of the uncertainties in the input signals combined wvith the additional uncertainty introduced by the summer itself. It is not clear that the summer uncertainty is included here.
M~q9ichlleoncharik-2OO4OO6~.ypd ag 3
NPPD Response The uncertainty of the flow loop is a combination of the uncertainties of the 2 flow elements, 2 flow transmitters, and the flow unit (which includes the summer) and is calculated in step 4.1.3.3.4..L b on pages 14 and 15 of 64, and in Appendix B. The assumption simply assumes that the As Left Tolerance (ALT) on the output of the summer is equal to twice the ALT of the two summer input values. Refer to diagram on page 23 and the values for ALTio and ALT,1 I on page 21 of the calculation.
- 16.
NRC Request Calculation Assumption 3.20: Show that the design basis limits on control room temperature are bounded by the temperature variation assumed in the derivation of the accuracy specification.
NPPD Response The GE design and performance specification for the APRM's specifies the uncertainty to be used based on environmental conditions (temperature and humidity), either in the "restricted" case or the "full" case. *For the 'restricted case' (which is used in the calculation), the temperature range is 60-90'F and humidity range of 40-50%RH. If the Control Room ambient temperature should increase above 90'F, station procedures direct the operator to commence a normnal plant shutdown, and if temperature exceeds 950F, to scram the reactor.

FY 2006 budget and AP1000 construction schedule Good morning, The purpose of this note is to let you know (1) what the FY2006 proposed budget is for construction inspection infrastructure, (2) previous FY2006 budget assumption and ramifications, and (3) to provide background on an AP1 000 CD that I placed in the mail for you.
FY2006 Proposed Budget My group (New Reactors Section) is currently in the process of developing the FY2006 budget for new reactors. The proposed FY2006 budget for inspection manual chapter development is the same as FY2005. There is also some regional budget to help support regional review of COL application guidance.
The overall regional budget for FY2006 is 2.9 FTE which is consistent with the FY2005 budget. The FY2006 budget allows for 1 FTE in Region II and 1II, 0.2 FTE in Region I and 0.7 FTE in Region IV.
(0.1FTE of Region IV's budget also assumes a small amount of work to support the tail end of the Grand Gulf ESP review).
FY2006 Change in Assumption The program review committee (PRC) (consisting of senior NRC managers) has determined that they will supply no resources in FY 2006 to support a COL application reivew. This information has not yet been shared with industry and goes against what NEI is telling us (i.e., expect one COL application in mid to late calendar year 2006). I guess that the PRC is rolling the dice that if we do receive a COL application it will be late in the fiscal year and that we will be able to delay the start of the review until FY2007.
Anyway the reason that the PRC assumption is important is because there is a large amount of inspection resources tied to the beginning of a COL application. The budget assumption for a COL application is that modular fabrication would begin around the same time as the COL application is submitted. This assumption leads to heavy regional and headquarters resource expenditures (approx 15 FTE for the 1st year of a COL application - 7 FTE to write plant specific procedures and 8 FTE to do inspections in the field). These budget numbers are based on the future licensing and inspection readiness assessement SECY paper. I'm not sure how and if we will adjust these numbers as more information comes to light regarding the status of a COL application, but I wanted to make you aware of the obvious (i.e., a COL application could have a large impact on regional resources)
AP1000 CD I sent all of you in the mail a CD that contains two AP1000 video files. The first file shows the construction sequence for the nuclear island through the first 3 months (starting with concrete placement). The modules first appear "green" the day that they are placed and turn to pink after their placement is completed. The second video is a flythrough of one of the first large modules placed on the nuclear island. The videos are non-proprietary and are consistent with the presentations that Westinghouse has shown us in the past regarding the rapid pace of construction.
Please let me know if you have any questions about the above.
- Thanks, Joe
