OVERVIEW / SIGNATURES1 Facility: Arkansas Nuclear One, Unit 1                                    Evaluation # FFN-2018-001 / Rev. #: 0 Proposed Change / Document:            EC 69811 Cycle 28 Reload, Core Operating Limits Report (COLR)
Refueling Boron (RFB) concentration limit change and reanalysis of the Moderator Dilution Accident (MDA) event during refueling conditions Since the MDA during refueling was required to be re-run to demonstrate that all required safety functions and design requirements are met, the change is considered to be adverse and must be screened in.
Description of Change:
EC 69811 Cycle 28 Reload Process Applicability Determination (PAD) identified an adverse change. The Cycle 28 reload report and reload technical document identified that the Analysis of Record (AOR) for the MDA event during refueling conditions was reanalyzed based on the Cycle 28 specific RFB concentration that is provided in the COLR. The guidance provided in CR-HQN-2015-00684 CA 4 and Revision 1 to NEI-96-07 which states: If the effect of a change is such that existing safety analyses would no longer be bounding and therefore UFSAR safety analyses must be re-run to demonstrate that all required safety functions and design requirements are met, the change is considered to be adverse and must be screened in, requires the change to the COLR RFB concentration limit and the MDA event during refueling be evaluated under the 10 CFR 50.59 process. This evaluation does not address the entire Cycle 28 reload, it will only address the COLR change to the Cycle 28 specific RFB concentration limit and the MDA event during refueling change.
Summary of Evaluation:
EC 69811, ANO-1 Cycle 28 PAD identified an adverse change. The adverse change is associated with the change in the RFB concentration limit reported in the COLR and the Cycle 28 reload reanalysis of the MDA event during refueling conditions based on the Cycle 28 COLR RFB concentration limit. The limit on the RFB concentration ensures the reactor remains subcritical during refueling (Mode 6). The RFB concentration limit specified in the COLR ensures an overall core reactivity of Keff  0.99 during fuel handling, with all control rods out (ARO) and fuel assemblies assumed to be in the most adverse configuration (least negative reactivity) allowed by unit procedure. The criteria for reactor protection for the MDA event during refueling is the core shall remain subcritical.
Boron, in the form of boric acid in the reactor coolant, controls excess reactivity. During refueling or maintenance operations when the reactor closure head has been removed (Mode 6), the Reactor Coolant System (RCS) boron concentration is procedurally controlled to assure a minimum Shutdown Margin (SDM) that is greater than the change in reactivity that would result from a dilution event. In these conditions, the sources of dilution water to the makeup tank and therefore to the RCS are isolated and the makeup pumps are not operating. To ensure the ability of the reactor to tolerate a moderator dilution during refueling, the consequences of accidentally filling the makeup tank with dilution water and starting the makeup pumps are evaluated. The results of this evaluation are used to demonstrate the COLR required RFB concentration limit is sufficient to prevent criticality following a dilution event.

QUALITY RELATED        EN-LI-101           REV. 15 NUCLEAR MANAGEMENT MANUAL                       INFORMATIONAL USE              PAGE 2 OF 7 10 CFR 50.59 Evaluations ATTACHMENT 9.1                                                                            50.59 EVALUATION FORM The evaluation of the dilution during a refueling accident demonstrates that the COLR required RFB concentration limit is sufficient to prevent criticality following a dilution event. This evaluation is performed for each new fuel cycle. The COLR RFB concentration limit is the boron concentration required to maintain the reactor subcritical by at least 1% k/k with all control rods removed from the core. A dilution event from the RFB concentration results in a reduced boron concentration. This reduced boron concentration is required to remain higher than the critical boron concentration for the refueled core configuration with the two most reactive control rods withdrawn.
The refueling evaluation assumes a conservatively small volume of RCS water will be diluted by the injection of a makeup tank full of deborated water. The volume of water assumed to be diluted corresponds to the minimum reactor vessel level allowed for maintenance activities with the fuel in the core, plus the volume of the smaller of the two decay heat removal loops (one of the loops must be in operation to allow the dilution water to mix with the vessel water). Water in the refueling canal is conservatively assumed not to be diluted. The change in concentration caused by the dilution is independent of the rate at which the dilution occurs.
Reference 3 specifies the COLR required RFB concentration limit to be used for Cycle 28 and indicates that this RFB concentration is sufficient to maintain the core subcritical by at least 1 %k/k with ARO.
The MDA during refueling evaluation is performed for each new cycle. For Cycle 28 this evaluation, as documented in the Reference 1 Reload Report, the Reference 2 Reload Technical Document, and the Reference 3 Core Load Plan, verified that the Cycle 28 specific COLR required RFB concentration is sufficient to protect from a dilution event. As previously stated, Reference 3 indicates that the Cycle 28 COLR required RFB concentration limit is sufficient to maintain the core subcritical by at least 1 %k/k with ARO and also reports that the core will remain subcritical by at least 1 %k/k in the event of a MDA during refueling.
Throughout this evaluation, any reference to MDA analysis specifically refers to the MDA analysis during refueling conditions (Mode 6).

Does the proposed Change:
: 1. Result in more than a minimal increase in the frequency of occurrence of an accident                Yes previously evaluated in the SAR?                                                                    No BASIS:
The Cycle 28 reload safety analysis required a Cycle 28 specific analysis of the MDA event during refueling conditions. This Cycle 28 specific MDA analysis during refueling conditions is the new reload AOR and was performed based on the change to the COLR RFB concentration limit.
The MDA event during refueling conditions relates to the Safety Analysis Report (SAR)
Section 14.1.2.4 analysis. SAR Section 14.1.2.4 assumes the dilution accident occurs. The change in the Cycle 28 COLR RFB concentration limit and the Cycle 28 MDA analysis based on the Cycle 28 COLR RFB concentration limit does not impact the occurrence of the dilution accident but is relevant to the accident results. The revised MDA analysis evaluates the impact of Cycle 28 specific reload related parameters on the severity of the accident to ensure the results remain within required limits. The Cycle 28 COLR RFB concentration limit and MDA analysis do not affect the accident initiators. The Cycle 28 MDA during refueling analysis confirms the COLR required RFB concentration is sufficient to protect from a dilution event during refueling conditions. The results of the analysis verify the core remains subcritical by at least 1 %k/k. The change does not create any new system interactions that could cause an accident.
The change in the Cycle 28 COLR RFB concentration limit and the Cycle 28 MDA analysis during refueling based on the COLR RFB concentration limit do not result in more than a minimal increase in the frequency of occurrence of an accident previously evaluated in the SAR.
: 2. Result in more than a minimal increase in the likelihood of occurrence of a malfunction             Yes of a structure, system, or component important to safety previously evaluated in the                No SAR?
BASIS:
The Cycle 28 COLR RFB concentration limit confirms the core remains subcritical by at least 1 %k/k with ARO during Mode 6. The Cycle 28 MDA analysis based on the COLR RFB concentration confirms the core remains subcritical by at least 1 %k/k in the event of a dilution accident. Therefore, there is no increase in the probability of fuel failure. No changes to the plant equipment are required due to the Cycle 28 COLR RFB concentration limit or MDA analysis. The Cycle 28 COLR RFB concentration limit and MDA analysis do not require any equipment important to safety to be operated in a different manner or at a higher duty. The Cycle 28 COLR RFB

Instrumentation accuracy and response characteristics are not impacted. The MDA analysis and COLR RFB concentration limit do not increase the probability of a malfunction of equipment important to safety.
The change in the Cycle 28 COLR RFB concentration limit and the Cycle 28 MDA analysis during refueling based on the COLR RFB concentration limit do not result in more than a minimal increase in the likelihood of occurrence of a malfunction of a structure, system, or component (SSC) important to safety previously evaluated in the SAR.
: 3. Result in more than a minimal increase in the consequences of an accident previously              Yes evaluated in the SAR?                                                                             No BASIS:
The COLR RFB concentration limit and MDA event during refueling conditions were analyzed for Cycle 28 using NRC approved analysis methods (BAW-10179P-A, Safety Criteria and Methodology for Acceptable Cycle Reload Analysis) under approved quality assurance programs. The analytical method used for Cycle 28 is the same as was used in previous cycles. The consequence of the dilution event is a decrease in shutdown margin (SDM). The Cycle 28 MDA analysis confirms that the COLR RFB concentration limit is sufficient to maintain the core subcritical by at least 1 %k/k in the event of a MDA during refueling conditions. There are no increases in the radiological dose consequences as no fuel failure is caused by the event.

The COLR required RFB concentration limit was confirmed to bound the MDA event during refueling conditions for Cycle 28. This confirms the Cycle 28 core can be operated safely and can be expected to meet license requirements for accident response. The function and duty of SSCs important to safety as assumed in safety analysis are not altered. The change to the Cycle 28 COLR RFB concentration limit and the MDA during refueling analysis do not place greater reliance on any specific plant SSC to perform a safety function. No changes in the assumptions concerning equipment availability or failure modes have been made and none are necessary for the change to the Cycle 28 COLR RFB concentration limit and the MDA during refueling analysis.
The change in the Cycle 28 COLR RFB concentration limit and the Cycle 28 MDA during refueling analysis based on the COLR RFB concentration limit do not result in an increase in the consequences of a malfunction of a SSC important to safety previously evaluated in the SAR.

The MDA during refueling analysis is part of the reload safety analyses for Cycle 28 that are performed to demonstrate compliance with design basis limits for fuel cladding, RCS pressure boundary, and containment fission product barriers. The Cycle 28 COLR RFB concentration limit was confirmed to maintain the core subcritical by at least 1%k/k in the event of a moderator dilution accident during refueling conditions. Therefore, the COLR RFB concentration limit and the Cycle 28 MDA during refueling analysis do not affect the ability of the fuel cladding to maintain its integrity as a fission product barrier.

The COLR was changed to reflect the Cycle 28 specific RFB concentration limit. The Cycle 28 reload safety analysis required a Cycle 28 specific analysis of the MDA event during refueling conditions. This Cycle 28 specific MDA during refueling analysis is the new AOR. The MDA during refueling analysis evaluates the impact of Cycle 28 specific reload related parameters on the severity of the accident to ensure the results remain within required limits. Both the RFB concentration and the MDA during refueling analysis use the same NRC approved method (BAW-10179P-A) of evaluation as previous cycles under an approved quality assurance program.
The methods are described in SAR Section 14.1.2.4.3. No new methods were required to calculate the COLR RFB concentration or for the MDA during refueling analysis.
The change in the Cycle 28 COLR RFB concentration limit and the Cycle 28 MDA during refueling analysis based on the COLR RFB concentration limit do not result in a departure from a method of evaluation described in the SAR used in establishing the design bases or in the safety analyses.
If any of the above questions is checked Yes, obtain NRC approval prior to implementing the change by initiating a change to the Operating License in accordance with NMM Procedure EN-LI-103.

The program is described in new SAR Section 18.1.35. Both fouling and loss of material are adequately managed by the Service Water (SW) integrity program and the oil analysis programs, so further inspection under the PSPM program for 2P-89A, 2P-89B, and 2P-89C are not required to manage aging effects of the High Pressure Safety Injection pump bearing cooling units. During development of a repetitive activity for the Emergency Diesel Generator (EDG) and Alternate AC Diesel Generator (AACDG) expansion joints to perform nondestructive examination (NDE) ultrasonic thickness (UT) readings on the expansion joints, it was determined that UT readings of the metal expansion joints was not possible based on the closeness of the convolutions and size of the joints.

Expansion joints are examined concurrently with other related EDG inspections, and the frequency of inspection for the expansion joints is in accordance with the PSPM program. The 2C-7 Atlas COPCO model LT-20-30 twin cylinder reciprocating starting air unit and the 2M-10 heatless regenerative desiccant dryer system were replaced with an air compressor/dryer system which utilizes a Sauer model WP65L compressor and air products membrane dehydrator. An air dryer with dew point measurement is not available on the new unit. The new unit is equivalent to the existing compressor/dryer (2C-7A).
Preventative maintenance (PM) is performed on each unit to ensure significant moisture is not entrained in the system; however, dew point on the AACDG starting air dryer will not be monitored.

This commitment was deleted by letter 2CAN041801.
Subsequent review has determined that it would have been more appropriate to clarify the commitment rather than delete it; therefore, the commitment is being reinstated as clarified below.
Clarification: The ANO-2 RVH Penetration Program was based on NRC Order EA 009. Since program Aging     Maintain the Reactor Vessel Head inception, the NRC has promulgated 10 CFR 50.55a, 17927   12/02/2003 06/27/2018                                               introducing a rule that all pressurized water reactor Management   (RVH) Penetration Program licensees include the requirements of American Society of Mechanical Engineers Code Case N-729, Alternative Examination Requirements for PWR Vessel Upper Heads with Nozzles having Pressure-Retaining Partial-Penetration Welds, in the Inservice Inspection (ISI) Program. Entergy has augmented the ISI program with N-729 requirements as required by 10 CFR 50.55a(g)(6)(ii)(D)(1) through (4),
thereby superseding the requirements of EA-03-009.
Consequently, since the inspections required by the RVH Penetration Program have been superseded by 10 CFR 50.55a, the specific commitment as outlined in the LRA is being clarified to meet the ASME Code Case N-729 instead of the NRC Order EA-03-009.
