ENCLOSURE A Application for Technical Specification Improvement to Adopt TSTF-476, Revision 1, "Improved Banked Position Withdrawal Sequence (BPWS) Control Rod Insertion Process (NEDO-33091)"
1.0 DESCRIPTION
This letter is a request to amend Operating License DPR-49 for the Duane Arnold Energy Center (DAEC). The proposed changes would revise the Bases sections of Technical Specification (TS) 3.1.6, "Rod Pattern Control," and 3.3.2.1, "Control Rod Block Instrumentation," along with TS Table 3.3.2.1-1, "Control Rod Block Instrumentation," to allow reference to an improved, optional Banked Position Withdrawal Sequence (BPWS) for use during reactor shutdown. The new BPWS is described in Topical Report NEDO-33091-A, Revision 2, "Improved BPWS Control Rod Insertion Process,"
dated July 2004, and approved by the NRC by a Safety Evaluation (SE) dated June 16, 2004 (ML041700479). Technical Specification Task Force (TSTF) change traveler TSTF-476, Revision 1, "Improved BPWS Control Rod Insertion Process (NEDO-33091)"
was announced for availability in the Federal Register on May 23, 2007 (72 FR 29004) as part of the consolidated line item improvement process (CLIIP).
2.0 PROPOSED CHANGE
S Consistent with NRC-approved TSTF-476, Revision 1, the proposed TS change includes:
- 1. Revised TS Section 3.1.6 Bases to allow use of an optional BPWS during plant shutdown.
- 2. Revised TS Section 3.3.2.1 Bases to allow reprogramming of the rod worth minimizer during the optional BPWS shutdown sequence.
- 3. Revised TS Table 3.3.2.1-1, "Control Rod Block Instrumentation," which adds a footnote that allows operators to bypass the rod worth minimizer if conditions for the optional BPWS shutdown process are satisfied.
3.0 BACKGROUND
The background for this application is as stated in the model SE in NRC's Notice of Availability published on May 23, 2007 (72 FR 29004), the NRC Notice for Comment published on May 3, 2006 (71 FR 26118) and TSTF-476, Revision 1.
ENCLOSURE A
4.0 TECHNICAL ANALYSIS
FPL Energy Duane Arnold LLC (FPL Energy Duane Arnold) has reviewed NEDO-33091-A, Revision 2, and the staff's SE dated June 16, 2004, as well as TSTF-476, Revision 1, and the model SE published on May 23, 2007 (72 FR 29004) as part of the CLIIP Notice for Comment. FPL Energy Duane Arnold has applied the methodology in NEDO-33091-A, Revision 2 to develop the proposed TS changes. FPL Energy Duane Arnold has also concluded that the justifications presented in TSTF-476, Revision 1 and the model SE prepared by the NRC staff are applicable to the DAEC, and justify this amendment for the incorporation of the changes to the DAEC TS.
5.0 REGULATORY ANALYSIS
A description of this proposed change and its relationship to applicable regulatory requirements and guidance was provided in the NRC Notice of Availability published on May 23, 2007 (72 FR 29004), the NRC Notice for Comment published on May 3, 2006 (71 FR 26118), and TSTF-476, Revision 1.
5.1 Regulatory Commitments As discussed in the model SE published in Federal Register on May 23, 2007 (72 FR 29004) for this technical specification improvement, the following plant-specific verifications/commitments were performed. The safety evaluation for NEDO-33091-A explained that the potential for the control rod drop accident (CRDA) will be eliminated by the following changes to the operational procedures, which FPL Energy Duane Arnold has made:
- 1. Before reducing power to the low power setpoint (LPSP), operators shall confirm control rod coupling integrity for all rods that are fully withdrawn. Control rods that have not been confirmed coupled and are in intermediate positions must be fully inserted prior to power reduction to the LPSP. No action is required for fully-inserted control rods.
If a shutdown is required and all rods, which are not confirmed coupled, cannot be fully inserted prior to the power dropping below the LPSP, then the original/standard BPWS must be adhered to. The original/standard BPWS can be found in Licensing Topical Report (LTR) NEDO-21231, "Banked Position Withdrawal Sequence," January 1977, and is referred to in NUREG-1433 and NUREG-1434.
- 2. After reactor power drops below the LPSP, rods may be inserted from notch position 48 to notch position 00 without stopping at the intermediate positions.
However, GE Nuclear Energy recommends that operators insert rods in the same order as specified for the original/standard BPWS as much as is reasonably possible. If a plant is in the process of shutting down following
ENCLOSURE A improved BPWS with the power below the LPSP, no control rod shall be withdrawn unless the control rod pattern is in compliance with standard BPWS requirements.
In addition to the procedure changes specified above, the staff previously concluded, based on its review of NEDO-33091-A, that no single failure of the boiling water reactor control rod drive (CRD) mechanical or hydraulic system can cause a control rod to drop completely out of the reactor core during the shutdown process. Therefore, the proper use of the improved BPWS will prevent a CRDA from occurring while power is below the LPSP. FPL Energy Duane Arnold has verified, in accordance with NEDO-33091-A, Revision 2, that no single failure of the boiling water reactor CRD mechanical or hydraulic system can cause a control rod to drop completely out of the reactor core during the shutdown process.
6.0 NO SIGNIFICANT HAZARDS CONSIDERATION FPL Energy Duane Arnold has reviewed the proposed no significant hazards consideration determination published on May 23, 2007 (72 FR 29004) as part of the CLIIP. FPL Energy Duane Arnold has concluded that the proposed determination presented in the notice is applicable to the DAEC and the determination is hereby incorporated by reference to satisfy the requirements of 10 CFR 50.91(a).
7.0 ENVIRONMENTAL EVALUATION FPL Energy Duane Arnold has reviewed the environmental consideration included in the model SE published on May 23, 2007 (72 FR 29004) as part of the CLIIP. FPL Energy Duane Arnold has concluded that the staff's findings presented therein are applicable to the DAEC and the determination is hereby incorporated by reference for this application.

DAEC 3.3-20 TSCR-093
Rod Pattern Control B 3.1.6 BASES APPLICABLE Control rod patterns analyzed in Reference 1 follow the Banked SAFETY Position Withdrawal Sequence (BPWS). The BPWS is applicable ANALYSES from the condition of all control rods fully inserted to 10% RTP (continued) (Ref. 2). For the BPWS, the control rods are required to be moved in groups, with all control rods assigned to a specific group required to be within specified banked positions (e.g., between notches 08 and 12). The banked positions are established to minimize the maximum incremental control rod worth without being overly restrictive during normal plant operation. Generic analysis of the BPWS (Ref. 1) has demonstrated that the 280 cal/gm fuel damage limit will not be violated during a CRDA while following the BPWS Mmode of operation. The generic BPWS analysis (Ref. 8) also evaluates the effect of fully inserted, inoperable control rods not in compliance with the sequence, to allow a limited number (i.e., eight) and distribution of fully inserted, inoperable control rods. The Reduced Notch Worth Procedure (RNWP) (Ref. 9) is an extension of the BPWS and may be used at DAEC during control rod withdrawal to avoid high notch worth scrams.
When performing a shutdown of the plant, an optional BPWS control rod sequence (Ref. 10) may be used provided that all withdrawn control rods have been confirmed to be coupled. The rods may be inserted without the need to stop at intermediate positions since the possibility of a CRDA is eliminated by the confirmation that withdrawn control rods are coupled. When using the Reference 10 control rod sequence for shutdown, the Rod Worth Minimizer may be reprogrammedto enforce the requirementsof the improved BPWS control rod insertionprocess, or bypassed in accordance with the allowance provided in the Applicability Note for the Rod Worth Minimizer in Table 3.3.2.1-1.
In order to use the Reference 10 BPWS shutdown process, an extra check is required in orderto considera control rod to be "confirmed"to be coupled. This extra check ensures that no Single OperatorErrorcan result in an incorrectcoupling check.
Forpurposes of this shutdown process, the method for confirming that control rods are coupled varies depending on the position of the control rod in the core. Details on this coupling confirmation requirementare provided in site procedures, which conform to Reference 10. If the requirementsfor use of the BPWS control rod insertion process contained in Reference 10 are followed, the plant is considered to be in compliance with BPWS requirements, as requiredby LCO 3.1.6.
Rod Pattern Control satisfies Criterion 3 of 10 CFR 50.36(c)(2)(ii).

SAFETY ANALYSES, LCO, (Ref. 3). When operating < 90% RTP, analyses (Ref. 3) have and shown that with an initial MCPR __1.70, no RWE event will result APPLICABILITY in exceeding the MCPR SL. Also, the analyses demonstrate that when operating at _>90% RTP with MCPR >_1.40, no RWE event will result in exceeding the MCPR SL (Ref. 3). Therefore, under these conditions, the RBM is also not required to be OPERABLE.
- 2. Rod Worth Minimizer The RWM enforces a rod pattern which is consistent with the Banked Position Withdrawal Sequence (BPWS) to ensure that the initial conditions of the CRDA analysis are not violated. The analytical methods and assumptions used in evaluating the CRDA are summarized in References 4, 5, 6, 7, and 11. The standard BPWS requires that control rods be moved in groups, with all control rods assigned to a specific group required to be within specified banked positions. Requirements that the control rod sequence is in compliance with the BPWS are specified in LCO 3.1.6, "Rod Pattern Control."
When performing a shutdown of the plant, an optional BPWS control rod sequence (Ref. 11) may be used if the coupling of each withdrawn control rod has been confirmed. The rods may be inserted without the need to stop at intermediatepositions. When using the Reference 11 control rod insertionsequence for shutdown, the Rod Worth Minimizer may be reprogrammedto enforce the requirementsof the improved BPWS control rod insertionprocess, or it can be bypassed if it is not programmed to reflect the optional BPWS shutdown sequence, as permitted by the Applicability Note for the RWM in Table 3.3.2.1-1.
The RWM Function satisfies Criterion 3 of 10 CFR 50.36 (c)(2)(ii).
Since the RWM is a hardwired system designed to act as a backup to operator control of the rod sequences, only one channel of the RWM is available and required to be OPERABLE (Ref. 7).
Special circumstances provided for in the Required Action of LCO 3.1.3, "Control Rod OPERABILITY," and LCO 3.1.6 may necessitate bypassing the RWM to allow continued operation with inoperable control rods, or to allow correction of a control rod (continued)
