SUBJECT:

JOSEPH M. FARLEY NUCLEAR PLANT - NRC INTEGRATED INSPECTION REPORT 05000348/2005005, 05000364/2005005, AND 072000042/2005002

Dear Mr. Stinson:

On December 31, 2005, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your Joseph M. Farley Nuclear Plant, Units 1 and 2. The enclosed integrated inspection report documents the inspection findings, which were discussed on January 5, 2006, with Mr. Randy Johnson and other members of your staff.

The inspection examined activities conducted under your license as they relate to safety and compliance with the Commissions rules and regulations and with the conditions of your license.

The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel.

Based on the results of this inspection, two self-revealing findings of very low safety significance were identified both of which were determined to be violations of NRC requirements. Because these violations are of very low safety significance and were entered into your corrective action program, the NRC is treating these violations as non-cited violations (NCVs) consistent with Section VI.A of the NRC Enforcement Policy. If you contest these NCVs, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the United States Nuclear Regulatory Commission, ATTN:

Document Control Desk, Washington DC 20555-0001; with copies to the Regional Administrator, Region II; the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Resident Inspector at the Farley Nuclear Plant.

In accordance with 10 CFR 2.390 of the NRCs Rules of Practice, a copy of this letter, its enclosures, and your response (if any) will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of the

SNC 2 NRCs document system (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

SUMMARY OF FINDINGS

IR 05000348/2005-005, 05000364/2005-005, 072000042/200-5002; 10/01/2005-12/31/2005;

The report covered a three-month period of inspection by resident inspectors, a project engineer, reactor inspectors, an operations engineer, and health physicists. Two Green non-cited violations were identified. The significance of most findings is indicated by their color (Green, White, Yellow, or Red) using Inspection Manual Chapter (IMC) 0609, Significance Determination Process (SDP). Findings for which the SDP does not apply may be Green or be assigned a severity level after management review. The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process, Revision 3, dated July, 2000.

NRC-Identified and Self-Revealing Findings

Cornerstone: Mitigating Systems

C A Green, self-revealing non-cited violation (NCV) of 10 CFR 50.65(a)(4) was identified when the licensee failed to perform a required risk assessment following alignment of the 1-2K and 1-2L 600V load centers to their emergency power (Unit 1) supplies. This resulted in the risk being elevated from a Yellow to an Orange status without senior management concurrence and no additional compensatory actions.

This finding is more than minor because it impacted the Mitigating Systems Cornerstone attribute of equipment performance and adversely affected the cornerstone objective in that the licensee failed to perform a risk assessment following a change in actual plant configuration and did not establish compensatory measures consistent with the elevated outage risk. Based on an Incremental Core Damage Probability Deficit (ICDPD) of less than 1E-6, this finding is of very low safety significance (Green). This finding involved the cross cutting aspect of Human Performance in the area of Personnel for failure to follow procedure FNP-0-ACP-52.3.

(Section 1R13)

C A Green, self-revealing NCV of Technical Specification (TS) 5.4.1.a was identified for inadequate procedural controls to maintain reactor coolant system (RCS) water level instruments operable. The lack of adequate procedural controls resulted in one of the required water level instruments being isolated prior to lowering RCS water level.

This finding is greater than minor because it affected the procedure quality attribute and the Mitigating Systems Cornerstone objective, in that, procedural controls for operability of RCS level instrument were not appropriate to the circumstances. This finding was determined to be of very low safety significance because actual water level was at the level planned for the drain down. This finding involved the cross cutting aspect of Human Performance in the area of Organization in that procedural controls were not adequate. (Section 1R20)

Licensee-Identified Violations

None

a. Inspection Scope

Annual Review. The inspectors reviewed test results of FNP-0-ETP-4367, Performance Test for Unit 1 & 2 Colt-Pielstick (Large) Diesel Generator Jacket Water Heat Exchangers, for the 1B EDG to verify the licensee had adequately identified and resolved any potential heat exchanger deficiencies which could mask degraded performance, common cause heat sink performance problems that could increase risk, and heat sink performance problems that could result in initiating events or affect multiple heat exchangers in mitigating systems. The inspectors also reviewed UFSAR Section 9.5.5 and system design document A-181005, Diesel Generator System, to verify the acceptance criteria for FNP-0-ETP-4367 was appropriate. The inspectors walked down the 1B EDG room to verify the material condition of the heat exchangers was not degraded and that any existing deficiencies had been identified. The inspectors also reviewed the licensees CR database to verify that heat exchanger problems were being identified and resolved.

b. Findings

No findings of significance were identified.

1R08 Inservice Inspection (ISI) Activities

a. Inspection Scope

Piping Systems ISI. The inspectors reviewed the implementation of the licensees ISI program for monitoring degradation of the reactor coolant system boundary and the risk significant piping system boundaries. The inspectors selected a sample of American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code,Section XI required examinations and Code components in order of risk priority. The inspectors reviewed records and conducted independent inspections for the following nondestructive examination (NDE) activities to evaluate compliance with Technical Specifications (TS), ASME Section XI, and ASME Section V requirements, 1989 Edition, and to verify that indications and defects (if present) were appropriately evaluated and dispositioned in accordance with the requirements of ASME Section XI, IWB-3000 or IWC-3000 acceptance standards.

Visual Testing (VT):

  • APRI-4501 through 4504-1DM, Pressurizer Relief Nozzle and Three Pressurizer Safety Nozzles, ASME Class 1

The inspectors performed a review of an ISI related problem that was identified by the licensee and entered into the corrective action program. The inspectors reviewed the CR to confirm that the licensee had appropriately described the scope of the problem and had initiated corrective actions.

Boric Acid Corrosion Control Program (BACCP) ISI. The inspectors reviewed the licensees BACCP to ensure compliance with commitments made in response to NRC Generic Letter 88-05, Boric Acid Corrosion of Carbon Steel Reactor Pressure Boundary and Bulletin 2002-01, Reactor Pressure Vessel Head Degradation and Reactor Coolant Pressure Boundary Integrity.

The inspectors reviewed records and walked down of parts of the reactor building that are not normally accessible during at-power operations to evaluate compliance with licensee BACCP requirements and verify that the boric acid visual examinations focused on locations where boric acid leaks can cause degradation of safety significant components and that degraded or non-conforming conditions were properly identified in the licensees corrective action system.

The inspectors reviewed the licensees procedures for implementation of the boric acid corrosion control program to ensure that they were in compliance with available industry guidance. The inspectors reviewed the following eight engineering evaluations completed for boric acid found on reactor coolant system piping and components to verify that the minimum design code required section thickness had been maintained for the affected component(s). The inspectors also reviewed licencee corrective actions implemented for evidence of boric acid leakage to confirm that they were consistent with requirements of Section XI of the ASME Code and 10 CFR 50, Appendix B, Criterion XVI.

b. Findings

Introduction.

A Green, self-revealing non-cited violation (NCV) of 10 CFR 50.65(a)(4)was identified when the licensee failed to perform a required risk assessment following alignment of the 1-2K and 1-2L 600V load centers to their emergency power (Unit 1)supplies. This resulted in the risk being elevated from a Yellow to an Orange status without senior management concurrence and no additional compensatory actions.

Description.

On October 14, the licensee aligned 1-2K and 1-2L to their emergency power supplies in preparation for upcoming train outages during the Unit 2 refueling outage. The loads on these busses were mainly supportive of the Service Water (SW)system and consisted of SW Booster Pumps, SW Battery Chargers, SW Cyclone Separator, and motor operated valves allowing SW Emergency Recirculation to the SW pond. This activity had been included in the risk assessment, but was moved ahead of the prescribed time; therefore, the risk assessment was not accurate for actual plant conditions.

Procedure FNP-0-ACP-52.3, Mode 1, 2, 3 Risk Assessment, required that the Shift Supervisor (SS) perform a risk assessment for all unscheduled activities. The nights SS attempted to update the risk assessment, but was unsuccessful. On October 15, the days SS successfully calculated an Orange risk condition which required Operations Shift Superintendent and Operations Manager concurrence before authorizing work.

Believing this to be in error, the SS performed multiple outage risk calculations but was unable to clear the Orange risk condition with 1-2K and 1-2L on their emergency power supplies. The SS then realigned 1-2K and 1-2L to their normal power supplies to clear the Orange risk condition.

Analysis.

This finding is more than minor because it impacted the Mitigating Systems Cornerstone attribute of equipment performance and adversely affected the cornerstone objective in that the licensee failed to perform a risk assessment following a change in actual plant configuration and did not establish compensatory measures consistent with the elevated outage risk. This finding was evaluated using IMC 0609, Appendix K, Maintenance Risk Assessment Significance Determination Process, and based on an Incremental Core Damage Probability Deficit (ICDPD) of 1.03E-6 and no Risk Management Actions, this finding was initially assessed as greater than Green.

However, the licensees risk assessment model had not been updated to reflect a recent design change, which removed the SW booster pumps as the SW pump lubrication and cooling water source. Using a revised risk assessment model, which included this design change, the ICDPD was recalculated to be less than 1E-6, resulting in this finding being of very low safety significance (Green). This finding involved the cross cutting aspect of Human Performance in the area of Personnel for failure to follow procedure FNP-0-ACP-52.3.

Enforcement.

10 CFR 50.65(a)(4) requires that the licensee shall assess and manage the increase in risk that may result from proposed maintenance activities. Procedure FNP-0-ACP-52.3 implemented the requirements of 10 CFR 50.65 (a)(4) by requiring a risk assessment for all unscheduled activities. Contrary to the above, on October 14, 2005, a risk assessment was not performed after 600V load centers 1-2K and 1-2L were placed on their emergency power supplies. Because this finding is of very low safety significance and has been entered into the licensees corrective action program as CR 2005110094, this violation is being treated as an NCV in accordance with Section VI.A.1 of the NRC Enforcement Policy: NCV 05000364/2005005-01, Failure to Perform Risk Assessment.

1R15 Operability Evaluations

a. Inspection Scope

The inspectors reviewed the following five operability evaluations to verify they met the requirements of licensee procedures FNP-0-AP-16, Conduct of Operations and FNP-0-ACP-9.2, Operability Determination for technical adequacy, consideration of degraded conditions, and identification of compensatory measures. The inspectors reviewed the evaluations against the design bases, as stated in the UFSAR and Functional System Descriptions (FSDs) to verify system operability was not affected.

b. Findings

No findings of significance were identified.

1R19 Post Maintenance Testing

a. Inspection Scope

The inspectors reviewed the criteria contained in licensee procedures FNP-0-PMT-0.0, Post Maintenance Test Program, to verify post-maintenance test procedures and test activities for the following five systems/components were adequate to verify system operability and functional capability.

b. Findings

No findings of significance were identified.

1R20 Refueling and Other Outage Activities

a. Inspection Scope

Refueling Activities. The inspectors reviewed the following activities related to the Unit 2 refueling outage for conformance to licensee Procedure FNP-0-UOP-4.0, General Outage Operations Guideline, and FNP-1-UOP-4.1, Controlling Procedure for Refueling.

Surveillance tests were reviewed to verify results were within the TS required specification. Shut-down risk, management oversight, procedural compliance, and operator awareness were evaluated for each of the following activities. Documents reviewed are listed in the Attachment.

C Outage Risk Assessment C Cooldown C Core offload and reload C Reactor coolant instrumentation C Electrical system alignments and bus outages C Reactor vessel disassembly and assembly activities C Outage-related surveillance tests C Containment Closure C Low Power Physics Testing and Startup Activities C Clearance Activities C Decay Heat Removal and Spent Fuel Pool Cooling

b. Findings

Introduction.

A Green, self-revealing NCV of Technical Specification (TS) 5.4.1.a was identified for inadequate procedural controls to maintain reactor coolant system (RCS)water level instruments operable. The lack of adequate procedural controls resulted in one of the required water level instruments being isolated prior to lowering RCS water level.

Description.

On October 19, Unit 2 RCS water level was drained below the indicated pressurizer level in preparation for head removal. The drain down was conducted using procedure FNP-2-SOP-1.6, Draining The Reactor Coolant System. During the time the drain down occurred, the time to boil in the vessel was less than 15 minutes. Both trains of RHR were in service, but the steam generators were not available.

A temporary RCS level instrument was installed using FT-416 to provide an independent water level indication once the pressurizer was drained. The other independent water level indication came off a single tap of an RCS loop and provided indication on a tygon hose and LT-2965. Following shift turnover, control room operators observed that FT-416 was reading six feet below LT-2965. The licensee investigated this condition and found that the variable leg isolation valve was closed and the reference leg was disconnected. With the variable leg isolation valve closed, FT-416 would not have indicated any changes in RCS water level. This condition was not identified by control room operators during the drain down. The licensee determined that, prior to the drain down, control room operators had requested that instrumentation technicians vent LT-416 from the Pressurizer Relief Tank (PRT). This was accomplished by disconnecting the upper level connection from the PRT. However, due to miscommunications, the technician disconnected the upper connection and had also closed the variable leg isolation valve.

Analysis.

This finding is greater than minor because it affected the procedure quality attribute and the Mitigating Systems Cornerstone objective, in that, procedural controls for operability of RCS level instrument were not appropriate to the circumstances. This finding was determined to be of very low safety significance because actual water level was at the level planned for the drain down. This finding involved the cross cutting aspect of Human Performance in the area of Organization in that procedural controls were not adequate.

Enforcement.

TS 5.4.1.a requires that written procedures be implemented covering the activities listed in Regulatory Guide (RG) 1.33, Revision 2, Appendix A, February 1978.

RG 1.33, Appendix A, 9. d. 4. includes procedures for draining the reactor coolant system. Contrary to the above, on October 19, the licensee failed to provide procedures appropriate to the circumstances, which resulted in required water level instrument being inoperable when lowering RCS water level. Because this finding is of very low safety significance and has been entered into the licensees corrective action program as CR 2005110381, this violation is being treated as a NCV in accordance with Section VI.A.1 of the NRC Enforcement Policy: NCV 05000364/2005005-02, Failure to Provide Adequate Procedural Controls.

1R22 Surveillance Testing

a. Inspection Scope

The inspectors reviewed surveillance test procedures and either witnessed the test or reviewed test records for the following eight surveillance tests to determine if the tests adequately demonstrated equipment operability and met the TS requirements. The inspectors reviewed the activities to assess for preconditioning of equipment, procedure adherence, and valve alignment following completion of the surveillance. The inspectors reviewed licensee procedures FNP-0-AP-24, Test Control; FNP-0-M-050, Master List of Surveillance Requirements; and FNP-0-AP-16, Conduct of Operations; and attended selected briefings to determine if procedure requirements were met.

RADIATION SAFETY

Cornerstone: Occupational Radiation Safety

2OS1 Access Control To Radiologically Significant Areas ===

a. Inspection Scope

Access Controls. Licensee activities for controlling and monitoring worker access to radiologically significant areas and tasks were evaluated. The inspectors evaluated changes to and adequacy of procedural guidance; directly observed implementation of established administrative and physical radiological controls; appraised radiation worker and health physics technician (HPT) knowledge of and proficiency in implementing radiation protection activities; and assessed occupational exposures to radiation and radioactive material.

The inspectors directly observed controls established for workers and HPT staff in airborne radioactivity area, radiation area, high radiation area (HRA), locked high radiation area (LHRA), and very high radiation area (VHRA) locations. Controls and their implementation for LHRA and VHRA keys and for storage of irradiated material within the Unit 2 spent fuel pool (SFP) area were reviewed and discussed in detail.

Reviewed Unit 2 refueling outage tasks included reactor vessel head disassembly, removal from containment and temporary storage activities; removal of a penetration sample from the old reactor vessel head; steam generator sludge lance tasks; fuel off-load; scaffolding activities; radioactive filter change-out; and radioactive waste (radwaste) handling and storage. The inspectors attended pre-job briefings and reviewed radiation work permit (RWP) details to assess communication of radiological control requirements to workers. Occupational worker adherence to selected RWPs and HPT proficiency in providing job coverage was evaluated through direct observations and interviews with licensee staff. Electronic dosimeter (ED) alarm set points and worker stay times were evaluated against area radiation survey results with a focus on reactor vessel head disassembly and removal. Worker exposure as measured by ED and by licensee evaluations of skin doses resulting from discrete radioactive particle or dispersed skin contamination events since January 1, 2005, and during the current refueling outage activities were reviewed and assessed independently. For HRA tasks involving potentially significant dose rate gradients, e.g., reactor vessel head penetration sampling, the inspectors evaluated the potential for use of dosimeter multi-badging to monitor worker exposure.

Postings for access to radiologically controlled areas and physical controls for the Unit 2 containment and for Unit 1 and Unit 2 reactor auxiliary building (RAB) locations designated as LHRAs and VHRAs were evaluated during facility tours. The inspectors independently measured radiation dose rates or directly observed conduct of licensee radiation surveys and results for Unit 2 containment equipment and work locations, Unit 2 drumming/storage room, selected Unit 1 and Unit 2 RAB locations, and the temporary old reactor head storage location adjacent to the Old Steam Generator Storage Facility (OSGSF). Results were compared to current licensee surveys and assessed against established postings and radiological controls.

Licensee controls for airborne radioactivity areas with the potential for individual worker internal exposures of greater than 30 millirem Committed Effective Dose Equivalent were evaluated. For selected RWPs identifying potential airborne areas associated with refueling outage activities, the inspectors evaluated the implementation and effectiveness of administrative and physical controls including air sampling, barrier integrity, engineering controls, and postings. Licensee identification and assessment of potential radionuclide intakes by workers between January 1, 2005 through November 10, 2005, were reviewed and discussed.

Radiation protection activities were evaluated against UFSAR, TS, and 10 Code of Federal Regulations (CFR) Parts 19 and 20 requirements. Specific assessment criteria included UFSAR Section 11, Radioactive Waste Management, and Section 12, Radiation Protection; 10 CFR 19.12; 10 CFR 20, Subpart B, Subpart C, Subpart F, Subpart G, Subpart H, and Subpart J; TS Sections 5.4, Procedures, and 5.7, High Radiation Area Controls; and approved procedures. Documents reviewed are listed in the Attachment.

Problem Identification and Resolution. Licensee corrective action program (CAP)documents associated with access control to radiologically significant areas were reviewed and assessed. The inspectors evaluated the licensees ability to identify, characterize, prioritize, and resolve the identified issues in accordance with NMP-GM-GL-02, Corrective Action Program Details and Expectations Guideline, Version 2.0.

Licensee CR documents associated with access controls, personnel monitoring instrumentation, and personnel contamination events were reviewed. Documents reviewed are listed in the Attachment.

b. Findings

No findings of significance were identified.

OTHER ACTIVITIES

4OA1 Performance Indicator Verification

b. Findings

No findings of significance were identified.

4OA2 Identification and Resolution of Problems

.1 Daily Review

As required by Inspection Procedure 71152, "Identification and Resolution of Problems," and to help identify repetitive equipment failures or specific human performance issues for follow-up, the inspectors performed a daily screening of items entered into the licensees corrective action program. This review was accomplished by reviewing daily hard copy summaries of CRs and by reviewing the licensees electronic CR database.

.2 Annual Sample Review

a. Inspection Scope

The inspectors performed a detailed review of the history of issues resulting from water entering electrical pull boxes and damaging electrical cabling. In 2004, the 2E Service Water pump failed to start due to a corroded conductor that carries the signal to close the breaker and start the pump. CR 2004001493, AI 2004202088, and WOs S400424601 and S400424701 were reviewed to verify safety concerns were properly classified and prioritized for resolution; technical issues were evaluated and dispositioned to address operability and reportability; apparent cause determinations were sufficiently thorough; extent of condition, generic implications, common causes and previous history was adequately considered; and appropriate corrective actions (short and long-term) were implemented or planned in a manner consistent with safety and compliance. The inspectors also evaluated the documents against the requirements of the licensees corrective action program as delineated in Procedure NMP-GM-003, Corrective Action Program, and 10 CFR 50, Appendix B.

b. Findings and Observations

No findings of significance were identified. The inspectors reviewed FNP-0-GMP-60.1, General Inspection of Outdoor Electrical Duct Run Pull Boxes, and that a requirement to check all safety related pullboxes on a five year frequency had been included. Based on a review of the licensees responses to the sampled splices, discussion with the system engineer, and plant management, the inspectors concluded that the implementation of the corrective actions were thorough and adequate.

.3 Semi-Annual Trend Review

a. Inspection Scope

The inspectors performed a review of the licensees CAP and associated documents to identify trends that could indicate the existence of a more safety significant safety issue.

The inspectors review focused on CRs with corrective action that were not sufficiently comprehensive to reduce the likelihood or prevent recurrence of the condition. The review also considered the results of the daily inspector CAP item screening discussed in Section 4OA2.1, licensee trending efforts, and licensee human performance results.

The inspectors reviewed the licensee quarterly trend reports for May 2005 - July 2005, and August 2005 - October 2005, daily CRs, selected completed CRs, Maintenance Rule (a)(1) list, equipment health reports, and quality assurance reports to identify issues not recognized by the licensee. The inspectors compared and contrasted their results with the results contained in the licensees quarterly trend reports. Corrective actions associated with a sample of the issues identified in the licensees trend report were reviewed for adequacy. The inspectors also evaluated the reports against the requirements of the licensees CAP procedures FNP-0-AP-30.0, Corrective Action Reporting and NMP-GM-002-GL05, Corrective Action Program Trend Coding and Analysis Guideline, and the requirements of 10 CFR 50, Appendix B.

b. Assessments and Observations No findings of significance were identified. The inspectors noted that the licensee had identified adverse trends with mispositioned components and equipment clock resets.

These were the two most significant issues noted by the inspectors during the semi-annual review period. These were continuing into the next quarter (November 2005, December 2005) and had not been analyzed by the licensee as their trend quarter had not ended.

a. Inspection Scope

The inspectors reviewed the licensees final response to NRC Bulletin 2004-01, dated July 26, 2004. The inspectors verified that the licensees inspection activities conducted during this outage were consistent with their response.

The inspectors conducted an independent observation of the susceptible welds on the top of the pressurizer to ensure that the physical conditions of the pressurizer penetrations and welds were adequately inspected, and that there were no problems with debris, insulation, dirt, boron from other sources, physical layout, or viewing obstructions, which could have interfered with the identification of boric acid leakage.

Specifically, the inspectors observed three safety valve nozzles, the common relief valve nozzle, and the spray line. The inspectors also reviewed licensee records of the inspection of these nozzles.

b. Findings

No findings of significance were identified. Reporting Requirements are as follows:

a. For each of the examination methods used during the outage, was the examination:

1. Performed by qualified and knowledgeable personnel?

Yes. The licensee used a knowledgeable staff member certified as Level II, VT-2 examiner. The qualification and certification procedure referenced the industry standard ANSI/ANST CP-189, Standard for Qualification and Certification of Nondestructive Testing Personnel.

3. Able to identify, disposition, and resolve deficiencies?

Yes. The inspectors concluded that the licensees direct visual examinations were capable of detecting leakage from cracking in pressurizer penetrations if it had existed. This conclusion was based upon the inspectors' direct observations of pressurizer penetration locations, which were free of debris or deposits that could mask evidence of leakage in the areas examined. The inspectors also verified that the licensees procedures included guidance for proper disposition and investigation of any identified deficiencies.

4. Capable of identifying the leakage in pressurizer penetration nozzle or steam space piping components, as discussed in NRC Bulletin 2004-01?

The inspectors verified that the licensees examination personnel were capable of identifying any leakage in pressurizer penetration nozzles.

b. What was the physical condition of the penetration nozzle and steam space piping components in the pressurizer system?

Through observations, the inspectors verified that the metal reflective insulation had been removed. The licensee personnel performed a direct visual inspection of these pressurizer penetrations. Based on this examination, the area examined was generally clean and free of debris or deposits or other obstructions which could mask evidence of leakage.

c. How was the visual inspection conducted?

The licensees inspection personnel used the direct visual examination technique.

d. How complete was the coverage?

The licensee was able to view the entire circumference, 360°, around each penetration.

e. Could small boron deposits, as described in the Bulletin 2004-01, be identified and characterized?

The examination personnel were appropriately trained and qualified to identify small boron deposits as described in the bulletin.

f. What material deficiencies (i.e., cracks, corrosion, etc.) were identified that required repair?

There were no deficiencies identified that required repair.

g. What, if any, impediments to effective examinations, for each of the applied methods, were identified?

There were no impediments for an effective examination.

h. If volumetric or surface examination techniques were used for the augmented inspections, what process did the licensee use to evaluate and dispose any indications that may have been detected as a result of the examinations?

Not Applicable. No augmented surface or volumetric examinations were performed.

In accordance with the licensees response, only a Bottom Mounted Vessel (BMV)examination was conducted during this outage, and there were no indications identified that required further examination.

I. Did the licensee perform appropriate follow-up examinations for indications of boric acid leaks from pressure-retaining components in the pressurizer system?

Not Applicable. There were no indications of boric acid leaks from susceptible pressure-retaining components.
