SUBJECT:

PERRY NUCLEAR POWER PLANT NRC INTEGRATED INSPECTION REPORT 50-440/03-04

Dear Mr. Kanda:

On June 30, 2003, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your Perry Nuclear Power Plant. The enclosed report documents the inspection findings which were discussed on June 27, 2003, with Mr. T. Rausch, General Manager, 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, the inspectors identified four issues of very low safety significance (Green). The four issues were determined to involve violations of NRC requirements. However, because of their very low safety significance and because they have been entered into your corrective action program, the NRC is treating these issues as Non-Cited Violations in accordance with Section VI.A.1 of the NRCs Enforcement Policy.

If you contest the subject or severity of a Non-Cited Violation, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555-0001, with a copy to the Regional Administrator, U.S. Nuclear Regulatory Commission - Region III, 801 Warrenville Road, Lisle, IL 60532-4351; the Director, Office of Enforcement, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001; and the Resident Inspector Office at the Perry Nuclear Power Plant.

Since the terrorist attacks on September 11, 2001, NRC has issued five Orders and several threat advisories to licensees of commercial power reactors to strengthen licensee capabilities, improve security force readiness, and enhance controls over access authorization. In addition to applicable baseline inspections, the NRC issued Temporary Instruction 2515/148, "Inspection of Nuclear Reactor Safeguards Interim Compensatory Measures," and its subsequent revision, to audit and inspect licensee implementation of the interim compensatory measures required by order. Phase 1 of TI 2515/148 was completed at all commercial nuclear power plants during calender year 2002 and the remaining inspection activities for Perry are scheduled for completion in 2003. The NRC will continue to monitor overall safeguards and security controls at Perry.

In accordance with 10 CFR 2.790 of the NRC's "Rules of Practice," a copy of this letter and its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's 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 05000440/03-04; FirstEnergy Nuclear Operating Company; 04/01/03 - 06/30/03; Perry

Nuclear Power Plant; Access Control to Radiologically Significant Areas, Other Activities.

The report covered a 3-month period of baseline resident and regional inspection. The inspection was conducted by resident inspectors and regional inspectors. This inspection identified four Green issues all of which involved Non-Cited Violations (NCVs). The significance of most findings is indicated by their color (Green, White, Yellow, 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 NRC management review.

The NRCs 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-Revealed Findings

Cornerstone: Mitigating Systems

Green.

A self-revealed violation of Technical Specification 5.4 occurred on May 7, 2003, when the licensed operator at the controls left the at-the-controls and operations area of the control room without using the appropriate procedure for shift and relief turnover. During the individuals absence, a control room annunciator was received. When the alarm was not acknowledged, two licensed operators who were also in the at-the-controls area (conducting an emergency diesel generator (EDG) surveillance run) observed the at-the-controls operators absence and responded to the annunciator. Operations management was not made aware of the personnel error until approximately 16.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> later at which time a condition report was generated and the individual was relieved of licensed operator duties pending incident review and remediation.

The finding was more than minor because it could reasonably be viewed as a precursor to a significant event. In other circumstances, a second licensed operator may not have been in the control room. Additionally, the failure to promptly identify a performance deficiency was not consistent with site expectations. The finding was of very low safety significance because the annunciator was expected due to inclined fuel transfer system operation and the licensed operator was out of the at-the-controls area for only approximately 20 seconds. (Section 4OA5)

Cornerstone: Occupational Radiation Safety

Green.

A finding of very low safety significance was self-revealed during work in the reactor water clean up (RWCU) heat exchanger (HX) room when the licensee failed to provide continuous radiological surveillance (electronic telemetry dosimetry) as required by Technical Specification 5.7.4 for a worker in an area where a major portion of the body could receive in 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> a dose

>3000 mrem.

The finding was more than minor because the failure to provide continuous monitoring in a high radiation area resulted in an individual workers unplanned, unintended dose, and resulted from actions or conditions contrary to licensee Technical Specifications. This finding was associated with the Programs and Processes and Human Performance attributes of the Occupational Radiation Safety Cornerstone and affected the cornerstone objective of ensuring the adequate protection of worker health and safety from exposure to radiation. The finding was of very low safety significance because it did not involve as-low-as-is-reasonably-achievable (ALARA) planning or work controls, there was no overexposure or a substantial potential for an overexposure, and the ability to assess dose was not compromised. This was a violation of Technical Specification 5.7.4. (Section 2OS1)

Green.

A finding of very low safety significance was self-revealed during work in the RWCU HX room when the licensee failed to place dosimetry to properly reflect the highest whole body dose for the working position as required by licensee procedure HPI-C0005, Radiation Work Permit Surveys and Surveillances.

The finding was more than minor because the failure to place dosimetry to properly reflect the highest whole body dose for the working position resulted in an individual workers unplanned, unintended dose and resulted from actions or conditions contrary to licensee procedures. This finding was associated with the Programs and Processes attribute of the Occupational Radiation Safety Cornerstone and affected the cornerstone objective of ensuring the adequate protection of worker health and safety from exposure to radiation. The finding was of very low safety significance because it did not involve as-low-as-is-reasonably-achievable (ALARA) planning or work controls, there was no overexposure or a substantial potential for an overexposure, and the ability to assess dose was not compromised. This was a violation of licensee procedure HPI-C0005. (Section 2OS1)

Green.

A finding of very low safety significance was NRC-identified during work in the drywell when the licensee failed to properly control access to a locked high radiation area (LHRA), as required by Technical Specification 5.7.2 and 5.7.3.

The finding was more than minor because the failure to adequately control access to Technical Specification LHRAs had an impact on radiological safety (external dose) and if not corrected would become a more significant concern given the elevated dose rates that occur in accessible areas during refueling outages. The finding was associated with the Programs and Processes attribute of the Occupational Radiation Safety Cornerstone and affected the cornerstone objective of ensuring the adequate protection of worker health and safety from exposure to radiation. The finding was of very low safety significance because it did not involve ALARA planning or work controls, there was no overexposure or a substantial potential for an overexposure, and the ability to assess dose was not compromised. This was a violation of Technical Specification 5.7.3. (Section 2OS1)

Licensee-Identified Violations

A violation of very low safety significance, which was identified by the licensee has been reviewed by the inspectors. Corrective actions taken or planned by the licensee have been entered into the licensees corrective action program. This violation and corrective action tracking number are listed in Section 4OA7.

REPORT DETAILS

Summary of Plant Status

The plant began the inspection period at 82 percent power in coastdown to refueling outage 9 (RFO9). On April 4, the licensee commenced lowering reactor power for RFO9. After reducing power to approximately 20 percent, the licensee inserted a manual scram at 2:20 a.m. on April 5. The plant reached Mode 4 later that same day. The plant entered Mode 5 at 10:15 p.m. on April 7 when the first reactor pressure vessel stud was detensioned. Following completion of outage activities, the reactor achieved criticality on May 28, but was shutdown later that same day to repair a leak in the steam bypass and pressure control system.

Following repairs, the unit achieved criticality on May 29, entered Mode 1 on May 30, synchronized to the grid on May 31, and reached 100 percent power on June 4. The unit remained at or near 100 percent power for the remainder of the assessment period.

.2 Observation of Unannounced Fire Drill

a. Inspection Scope

The inspectors observed an unannounced drill concerning a fire in the emergency service water (ESW) pump house on June 9. The drill was observed to evaluate the readiness of licensee personnel to fight fires. The inspectors considered licensee performance in donning protective clothing/turnout gear and self-contained breathing apparatus, deploying firefighting equipment and fire hoses to the scene of the fire, entering the fire area in a deliberate and controlled manner, maintaining clear and concise communications, checking for fire victims and propagation of fire and smoke into other plant areas, smoke removal operations, and the use of pre-planned fire fighting strategies in evaluating the effectiveness of the fire fighting brigade. In addition, the inspectors attended the post-drill debriefing to evaluate the licensee's ability to self-critique fire fighting performance.

b. Findings

No findings of significance were identified.

1R07 Heat Sink Performance

a. Inspection Scope

The inspectors reviewed the licensees analysis of their emergency core cooling system (ECCS) room coolers to ensure the licensee adequately accounted for differences between measured performance and expected conditions during accidents. The inspectors also reviewed the licensees inspection frequency to verify it was sufficiently frequent to detect degradation of the room coolers. Finally, the inspectors performed a walkdown of the room coolers to verify they were in good condition and filters were not fouled.

b. Findings

No findings of significance were identified

1R08 Inservice Inspection Activities

a. Inspection Scope

The inspectors evaluated the implementation of the licensees inservice inspection program for monitoring degradation of the reactor coolant system boundary and risk significant piping system boundaries, based on review of records and in-process observation of nondestructive examinations.

On April 22, the inspectors observed:

C Ultrasonic (UT) examination of a 10 inch diameter pipe to valve weld 1E51-0124 in the reactor core isolation cooling (RCIC) system in the reactor building drywell; and, C Dye penetrant examination of 2 inch diameter drain system welds 1N22-0031, 0031A, 0031B, 0031C, 0141 and 0142 in the reactor building drywell.

The inspectors review of records occurred on-site in Maintenance Building 100 located within the site protected area.

b. Findings

No findings of significance were identified.

1R13 Maintenance Risk Assessments and Emergent Work Control

a. Inspection Scope

The inspectors reviewed the licensees evaluation of plant risk, scheduling, configuration control, and performance of maintenance associated with planned and emergent work activities, to verify that scheduled and emergent work activities were adequately managed. In particular, the inspectors reviewed the licensees program for conducting maintenance risk assessments to verify that the licensees planning, risk management tools, and the assessment and management of on-line and shutdown risk were adequate. The inspectors also reviewed licensee actions to address increased on-line and shutdown risk when equipment was out-of-service for maintenance, such as establishing compensatory actions, minimizing the duration of the activity, obtaining appropriate management approval, and informing appropriate plant staff, to verify that the actions were accomplished when on-line and shutdown risk was increased due to maintenance on risk-significant structures, systems, and components. The following specific assessments were reviewed:

  • the maintenance risk assessment for the week of March 31, which included modification of the emergency closed cooling water (ECCW) system and associated ECCW train A inoperability;
  • the daily shutdown safety risk assessments for the week of April 7, which included a planned entry into an Orange risk category due to use of a freeze seal as a reactor coolant system pressure boundary during replacement of Valve EP (equipment piece) - 102 associated with hydraulic control unit 22-19;
  • the daily shutdown safety risk assessments for the week of April 14, during which substantial schedule revisions were required due to a 48-hour stop-work order applied to all work in contaminated areas, high radiation areas (HRAs) and LHRAs;
  • the daily shutdown safety risk assessments for the week of May 12, which included emergent ESW A work; and
  • the daily shutdown safety risk assessments for the week of May 19, which included a planned entry into a yellow risk configuration due to time-to-boil being less than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> and emergent inboard main steam isolation valve C work.

b. Findings

No findings of significance were identified.

1R14 Operator Performance During Non-Routine Plant Evolutions and Events

a. Inspection Scope

As discussed in Section 4OA3, on April 24, the licensee received unexpected fuel handling building (FHB) radiation and evacuation alarms after an irradiated fuel rod was inadvertently damaged during inspection activities. The inspectors reviewed and observed licensee recovery plans including problem solving team meetings, infrequently performed test and evolution briefings, and the rechanneling and movement of the damaged fuel bundle on April 26. Specifically, the inspectors verified the licensees recovery plans were consistent with operating instructions, ONIs, and emergency plan requirements; verified the infrequently performed test and evolution briefings met criteria specified in Plant Administrative Procedure (PAP)-1121, Conduct of Infrequently Performed Tests of Evolutions, Rev. 1; and verified the actual work met licensee standards and expectations with respect to procedure usage, crew communications, and work control.

b. Findings

No findings of significance were identified.

1R15 Operability Evaluations

a. Inspection Scope

The inspectors selected condition reports (CRs) related to potential operability issues for risk significant components and systems. These CRs were evaluated to determine whether the operability of the components and systems was justified. The inspectors compared the operability and design criteria in the appropriate sections of the Technical Specifications (TSs) and Updated Safety Analysis Report (USAR) to the licensees evaluations to verify that the components or systems were operable. Where compensatory measures were required to maintain operability, the inspectors verified that the measures were in place, would work as intended, and were properly controlled.

Additionally, the inspectors verified, where appropriate, compliance with bounding limitations associated with the evaluations. The inspectors reviewed:

  • an engineering evaluation of the consequences of discrepancies in ECCS room cooler calculations on ECCS room equipment;
  • an operability determination associated with potential vortexing at the fuel oil transfer system eductor suction nozzle which would prevent adequate transfer of fuel oil from the EDG fuel oil storage tanks; and
  • an operability evaluation concerning an adverse trend in RCIC lube oil sample results.

b. Findings

No findings of significance were identified.

1R16 Operator Workarounds (OWAs)

.1 Cumulative Review

a. Inspection Scope

The inspectors evaluated the overall effectiveness of the licensee OWA program. The inspectors reviewed the licensees CRs in order to determine if issues identified in the corrective action program were also reviewed as part of and captured in the licensees OWA program. Additionally, the inspectors discussed the effect of active OWAs with operators and operations management. Finally, the inspectors reviewed OWAs closed during RFO9 to verify the adverse conditions were corrected as scheduled and to assess the effectiveness of the corrective actions.

b. Findings

No findings of significance were identified.

.2 Lost Control Rod Position Indication

a. Inspection Scope

The inspectors observed the operators response to a control rod with intermittent valid position indication. As a result of the problem, the operators lost the ability to move control rods. The inspectors observed licensee actions to bypass the affected control rods, communicate the condition to shift personnel and restore the ability to move controls. The inspectors verified the actions were consistent with procedural guidance and technical specification requirements.

b. Findings

No findings of significance were identified.

1R17 Permanent Plant Modifications

a. Inspection Scope

The inspectors reviewed Engineering Change Package 02-0213A which implemented a plant modification to permanently eliminate the interconnection between the A loop of ECCW and the nuclear closed cooling system. The inspectors reviewed associated safety evaluations and design criteria to evaluate the impact of the modification on the design basis, licensing basis, and interfacing systems. The inspection included observation of installation activities and discussions with key project personnel.

Additionally, the inspectors reviewed the final system configuration against revised system drawings and control room panel depiction.

b. Findings

RADIATION SAFETY

Cornerstone: Occupational Radiation Safety

2OS1 Access Control to Radiologically Significant Areas (71121.01)

.1 Review of Licensee Performance Indicators for the Occupational Exposure Cornerstone

a. Inspection Scope

The inspectors reviewed the licensees performance indicators (PIs) to determine whether or not the conditions surrounding the PIs had been evaluated, and identified problems had been entered into the corrective action program for resolution.

b. Findings

No findings of significance were identified.

.2 Plant Walkdowns and Radiation Work Permit Reviews

a. Inspection Scope

The inspectors identified three radiologically significant work areas within radiation areas, high radiation areas and airborne radioactivity areas in the plant and reviewed work packages which included associated licensee controls and surveys of these areas to determine if radiological controls including surveys, postings and barricades were acceptable. These work areas were walked down and surveyed (using an NRC survey meter) to verify that the prescribed radiation work permit (RWP), procedures, and engineering controls were in place, that licensee surveys and postings were complete and accurate, and that air samplers were properly located.

The inspectors reviewed the RWPs and work packages used to access these and other high radiation work areas to identify the work control instructions and control barriers that had been specified. Technical Specification HRA and LHRA requirements were used as the licensees standards for the necessary barriers. Electronic dosimeter alarm set points for both integrated dose and dose rate were evaluated for conformity with survey indications and plant policy. Workers were interviewed to verify that they were aware of the actions required when their electronic dosimeters noticeably malfunctioned or alarmed.

The inspectors reviewed the available RWPs for airborne radioactivity areas to determine if there was a potential for individual worker internal exposures of >50 mrem committed effective dose equivalent. Barrier integrity and engineering controls performance such as high-efficiency particulate air ventilation system operation were evaluated. Work areas having a history of, or the potential for, airborne transuranics were evaluated to verify that the licensee had considered the potential for transuranic isotopes and provided appropriate worker protection. The adequacy of the licensees internal dose assessment process for internal exposures >50 mrem committed effective dose equivalent was assessed.

b. Findings

No findings of significance were identified.

.3 Problem Identification and Resolution

a. Inspection Scope

The inspectors reviewed the licensees self-assessments, audits, Licensee Event Reports, and Special Reports related to the access control program to verify that identified problems were entered into the corrective action program for resolution. This included 15 corrective action reports related to access controls and three HRA radiological incidents when available (non-PIs identified by the licensee in HRAs

<1R/hr). Staff members were interviewed and corrective action documents were reviewed to verify that follow-up activities were being conducted in an effective and timely manner commensurate with their importance to safety and risk based on the following:

  • initial problem identification, characterization, and tracking;
  • disposition of operability/reportability issues;
  • evaluation of safety significance/risk and priority for resolution;
  • identification of repetitive problems;
  • identification of contributing causes;
  • identification and implementation of effective corrective actions;
  • resolution of NCVs tracked in the corrective action system; and
  • implementation/consideration of risk significant operational experience feedback.

The inspectors evaluated the licensees process for problem identification, characterization, prioritization, and verified that problems were entered into the corrective action program and resolved. For repetitive deficiencies and/or significant individual deficiencies in problem identification and resolution, the inspectors verified that the licensees self-assessment activities were capable of identifying and addressing these deficiencies.

The inspectors reviewed licensee documentation packages for all PI events occurring since the last inspection to determine if any of these PI events involved dose rates

>25 R/hr at 30 cm or >500 R/hr at 1 meter. Barriers were evaluated for failure and to determine if there were any barriers left to prevent personnel access. Unintended exposures >100 mrem total effective dose equivalent (or >5 rem shallow dose equivalent or >1.5 rem lens dose equivalent) were evaluated to determine if there were any regulatory overexposures or if there was a substantial potential for an overexposure.

b. Findings

No findings of significance were identified.

.4 Job-In-Progress Reviews

a. Inspection Scope

The inspectors selected three jobs being performed in radiation areas, airborne radioactivity areas, or HRAs for observation of work activities that presented the greatest radiological risk to workers. This involved work that was estimated to result in the highest collective doses, and included diving activities in the spent fuel pool, and other work areas where radiological gradients were present.

The inspectors reviewed radiological job requirements including RWP requirements and work procedure requirements, and attended ALARA job briefings. Job performance was observed with respect to these requirements to verify that radiological conditions in the work area were adequately communicated to workers through prejob briefings and postings. The inspectors also verified the adequacy of radiological controls including required radiation, contamination, and airborne surveys for system breaches; radiation protection (RP) job coverage which included audio and visual surveillance for remote job coverage; and contamination controls.

Radiological work in high radiation work areas having significant dose rate gradients was reviewed to evaluate the application of dosimetry to effectively monitor exposure to personnel and to verify that licensee controls were adequate. These work areas involved areas where the dose rate gradients were severe (diving activities and the HX room) which increased the necessity of providing multiple dosimeters and/or enhanced job controls.

b. Findings

Introduction:

The inspectors identified a NCV of TS 5.7.4 having very low safety significance (Green) for failing to provide continuous radiological surveillance (electronic telemetry dosimetry) for a worker in an area where a major portion of the body could receive in 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />, a dose >3000 mrem. This issue was self-revealed. The inspectors also identified a NCV of Procedure HPI-C0005 having very low safety significance (Green) for failing to place dosimetry to properly to reflect the highest whole body dose for the working position. This issue was also self-revealed.

Description:

On April 14, a pipe fitter (Worker A) received an unintended radiation exposure while working in the RWCU HX room. The plant was in RFO9 and the RWCU system was out of service for chemical decontamination. RP personnel were supporting work in the RWCU HX room which involved rotating the remaining three (of 16)spectacle flanges, which were located close to the HXs, as part of the chemical decontamination process. Substantial radiation dose gradients existed in the room as a result of hot spots on the HXs and associated piping. RP support personnel for this portion of the work consisted of an ALARA specialist, a lead RP technician (RPT) and a RP specialist (RPS). An Infrequently Performed Test or Evolution briefing and an ALARA briefing for the flange work were conducted. The workers were issued telemetry dosimetry (wireless remote monitoring system) to track their dose as the licensee had determined that telemetry dosimetry would be the only method for tracking worker exposure for this job. The electronic dosimeter set-points were 1000 mrem total dose and 15000 mrem/hour dose rate. Approximately 10 workers were on the telemetry dosimetry monitoring system. A television camera was located inside the RWCU room and provided visual monitoring of the workers. However, this camera was controlled by licensee personnel on the refueling floor and not by the RP staff controlling this job. The ALARA specialist and the RPT were outside of the RWCU room and the lead RPT was stationed just inside the room. One worker (A) noted to the RP staff that his telemetry screen entry was a different color than all of the other workers. Worker A then noticed that his name was no longer on the telemetry computer screen and he so informed the RPS. He was told that his name would come back later. A short time later Worker A noted to the RP staff that his name was still not on the telemetry read out. The worker was told that his name would probably show up again when he entered the RWCU room and he was told to talk to the lead RPT about the issue. The RPS did not expect Worker A to enter the RWCU room for work because he believed that the worker would notify the lead RPT inside the RWCU room that he was having a dosimetry problem and would be replaced. Worker A did not discuss his telemetry problem with the lead RPT and entered the RWCU room with the other two workers. However, the RP staff outside of the RWCU room did not realize that all three workers entered the area. Once inside, Workers A and B were in close proximity to each other but Worker A was not at his assigned flange and was unable to locate his correct work site. After some time he returned to the entrance of the room. The third worker (C) climbed a scaffold to upper elevations of the room to work on his flange. After Worker A returned to the alcove just inside the RWCU room to ask about the location of his work area, Worker B was reaching his limit of 800 mrem for the entry and all workers were told to return to the low dose waiting area just inside of the room. Worker B told Worker A where the flange was that Worker A was to work on, and Worker B left the area. Worker C asked for his dose and was told 57 mrem by the RPT who was outside of the room acting as the LHRA gate guard. Worker A also asked for his dose and was told 57 mrem, which he questioned. He was told that his reading was low and that he could return to work.

Both Workers A and C returned to work. Worker C then finished his task and exited the area. The RPS, who periodically had been observing the workers on a TV monitor that had a view of the lower area, had assumed that the worker who was showing increased dose on the telemetry (Worker C) was the same person he had seen on the monitor.

When the RPS noticed that a worker was still in the area with no one now in a dose field on the telemetry screen, he told the lead RPT to remove the worker from the RWCU room. When Worker A exited the room his electronic dosimeter registered 1834 mrem.

Worker A was in a significant radiological gradient at his assigned work site due to hot spots on the HX and on piping close to his work area. The licensees dose reconstruction determined that the portion of the body that was in the highest radiation field was the workers head. However, the licensee did not place the workers dosimetry on his head, but placed the dosimetry on the workers chest, which was the licensees standard practice.

Analysis 1: The inspectors determined that failing to provide continuous surveillance for workers in a HRA, where a major part of the body could receive in 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> a dose

>3000 mrem, was a performance deficiency warranting a significance evaluation. The inspectors concluded that the finding was greater than minor in accordance with IMC 0612, Power Reactor Inspection Reports, Appendix B, Issue Disposition Screening, issued on June 20, 2003. The issue is more than minor because the failure to provide continuous monitoring in HRAs resulted in an individual workers unplanned, unintended dose, and resulted from actions or conditions contrary to licensee TSs. The inspectors determined that the issue was associated with the Programs and Processes and Human Performance attributes of the Occupational Radiation Safety Cornerstone, and affected the cornerstone objective of ensuring adequate protection of worker health and safety from exposure to radiation from radioactive material during routine civilian nuclear reactor operations.

The inspectors completed a significance determination of this issue using IMC 0609, Significance Determination Process (SDP), dated March 21, 2003, Appendix C, Occupational Radiation Safety Significance Determination Process, dated June 24, 2003. The inspectors determined that the finding did not involve ALARA planning or work controls, there was no overexposure or a substantial potential for an overexposure, and the ability to assess dose was not compromised. The inspectors determined that there was no substantial potential for an overexposure because:

(1) a barrier analysis indicated that the worker would have been removed from the RWCU room before a regulatory overexposure would have occurred; and,
(2) the licensees dose calculations, based on a time and motion study which provided a realistic assessment of the workers dose, showed that the individual did not receive an overexposure and that a minor change in the circumstances would not have resulted in an overexposure. Consequently, the inspectors concluded that the SDP assessment for this finding was of very low safety significance (Green).

Enforcement 1: TS 5.7.4 requires, in part, that for individual areas accessible to personnel such that a major portion of the body could receive in 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />, a dose

>3000 mrem, entry shall require an approved RWP which will specify dose rate levels in the immediate work area and the maximum allowable stay time for individuals in that area. In lieu of the stay time specification of the RWP, continuous surveillance, direct or remote, such as use of closed circuit TV cameras, may be made by personnel qualified in RP procedures to provide positive exposure control over activities within the areas.

On April 14, the licensee used remote telemetry dosimetry as the only means of monitoring worker dose in the RWCU room. The telemetry system for one worker failed and the licensee was unable to monitor that workers radiological exposure. However, since the licensee conducted an immediate general work stand down to reevaluate RP job coverage, and documented this issue in its corrective action program (Root Cause Analysis Report: Unintended Exposure for RWCU Heat Exchanger Work; Condition Reports 03-02073, 03-02086, 03-02216, 03-03013, 03-02761, and 03-02255), and because the violation is of very low safety significance, the violation is being treated as a NCV (NCV 50-440/03-04-01).

Analysis 2: The inspectors determined that failing to place the workers dosimetry on that portion of the body that would be subjected to the highest dose rates was a performance deficiency warranting a significance evaluation. The inspectors concluded that the finding was greater than minor in accordance with IMC 0612, Power Reactor Inspection Reports, Appendix B, Issue Disposition Screening, issued on June 20, 2003. The issue is more than minor because the failure to place the dosimetry on that portion of the workers body that was in the highest dose rate resulted in an individual workers unplanned, unintended dose, and resulted from actions or conditions contrary to licensee procedures. The inspectors determined that the issue was associated with the Programs and Processes attribute of the Occupational Radiation Safety Cornerstone and affected the cornerstone objective of ensuring the adequate protection of worker health and safety from exposure to radiation from radioactive material during routine civilian nuclear reactor operations.

The inspectors completed a significance determination of this issue using IMC 0609, Significance Determination Process, dated March 21, 2003, Appendix C, Occupational Radiation Safety Significance Determination Process, dated June 24, 2003. The inspectors determined that the finding did not involve ALARA planning or work controls, there was no overexposure or a substantial potential for an overexposure, and the ability to assess dose was not compromised. The inspectors determined that there was no substantial potential for an overexposure because:

(1) a barrier analysis indicated that the worker would have been removed from the RWCU room before a regulatory overexposure would have occurred; and,
(2) the licensees dose calculations, based on a time and motion study which provided a realistic assessment of the workers dose, showed that the individual did not receive an overexposure and that a minor change in the circumstances would not have resulted in a substantial potential for an overexposure. Consequently, the inspectors concluded that the SDP assessment for this finding was of very low safety significance (Green).

Enforcement 2: TS 5.4.1 required, in part, that written procedures/instructions shall be established, implemented, and maintained covering the following activities recommended in Regulatory Guide 1.33, Revision 2, Appendix A, which included procedures for the RP program implementation. Procedure HPI-C0005, Radiation Work Permit Surveys and Surveillances, Section 6.5.1.3.a, required that dosimetry is placed properly to reflect the highest whole body dose for the working position. On April 14, the licensee sent a worker into the RWCU HX room, in which significant dose rate gradients existed, without placing the dosimetry on the area of the body that would have been exposed to the highest dose rates. As a result of this, the workers dosimeters did not accurately reflect the workers actual dose. However, since the licensee conducted an immediate general work stand down to reevaluate RP job coverage, and documented this issue in its corrective action program (TLD/MG 25 percent Dose Discrepancy Evaluation for CR 03-02216 RWCU HX Room; Condition Reports 03-02216 and 03-02073) and because the violation is of very low safety significance, the violation is being treated as a NCV (NCV 50-440/03-04-02).

.5 High Risk Significant, High Dose Rate HRA and Very High Radiation Area (VHRA)

Controls

a. Inspection Scope

The inspectors reviewed the licensees performance indicators for high risk, high dose rate and HRAs, and for VHRAs to verify that workers were adequately protected from radiological overexposure. Discussions were held with the RP Manager concerning high dose rate/HRA and VHRA controls and procedures, including procedural changes that had occurred since the last inspection, in order to verify that any procedure modifications did not substantially reduce the effectiveness and level of worker protection.

The inspectors discussed with RP supervisors the controls that were in place for special areas that had the potential to become VHRAs during certain plant operations, to determine if these plant operations (fuel transfer operations) required communication beforehand with the RP group, so as to allow corresponding timely actions to properly post and control the radiation hazards. During plant walkdowns, the posting and locking of entrances to high dose rate HRAs, and VHRAs were reviewed for adequacy.

b. Findings

Introduction:

An NRC-identified Green finding and an associated NCV were identified for the failure to properly control access to a LHRA, as required by TS 5.7.2.

Description:

On April 9, a radiation worker received an unexpected dose rate alarm while in an upper level of the drywell near the safety relief valves while performing a walkdown in preparation for safety relief valve work. The worker received a dose rate alarm of 328 mrem/hr with the alarm setpoint at 300 mrem/hr. The licensee had not fully surveyed the area of the drywell that the worker was in. Follow-up surveys revealed an area near nozzle N6A on an E12 line that was reading 6 rem/hr on contact and 2.5 rem/hr at 30 cm. Upon discovery, the area was guarded and the licensee verified that no one was in the immediate area. This area was then posted as a LHRA, was provided with a flashing light and a boundary.

Analysis:

The inspectors determined that failing to adequately control access to a TS LHRA was a performance deficiency warranting a significance evaluation. The inspectors concluded that the finding was greater than minor in accordance with IMC 0612, Power Reactor Inspection Reports, Appendix B, Issue Disposition Screening, issued on June 20, 2003. The issue is more than minor because the failure to adequately control access to a TS LHRA had an impact on radiological safety (external dose) and if not corrected would become a more significant concern given the elevated dose rates that occur in accessible areas during RFOs. The inspectors determined that the issue was associated with the Programs and Processes attribute of the Occupational Radiation Safety Cornerstone and affected the cornerstone objective of ensuring the adequate protection of worker health and safety from exposure to radiation from radioactive material during routine civilian nuclear reactor operations.

The inspectors completed a significance determination of this issue using IMC 0609, Significance Determination Process, dated March 24, 2003, Appendix C Occupational Radiation Safety Significance Determination Process, dated June 24, 2003. The inspectors determined that the finding did not involve ALARA planning or work controls, there was no overexposure or a substantial potential for an overexposure, and the ability to assess dose was not compromised. Consequently, the inspectors concluded that the SDP assessment for this finding was of very low safety significance (Green).

Enforcement:

TS 5.7.2 requires, in part, that areas accessible to personnel with radiation levels such that a major portion of the body could receive in1 hour a dose

>1000 mrem, shall be provided with locked or continuously guarded doors to prevent unauthorized entry. TS 5.7.3 provides that individual areas where no enclosure exists for the purpose of locking, and where no enclosure can reasonably be constructed around the individual areas, need not be controlled by a locked door or gate, but shall be barricaded, posted, and a clearly visible flashing light shall be activated at the area as a warning device.

Until April 9, the inspectors determined that the licensee had failed to adequately control access to the upper area of the drywell. However, since the licensee immediately posted the area, established a boundary and flashing light, and documented this issue in its corrective action program (Condition Report 03-01877), and because the violation is of very low safety significance, the violation is being treated as a NCV.

(NCV 50-440/03-04-03).

.6 Radiation Worker Performance

a. Inspection Scope

During job performance observations, the inspectors evaluated radiation worker performance with respect to stated RP work requirements and evaluated whether workers were aware of the significant radiological conditions in their workplace, the RWP controls and limits in place, and that their performance accounted for the level of radiological hazards present.

Radiological problem reports, which found that the cause of the event was due to radiation worker errors, were reviewed to determine if there was an observable pattern traceable to a similar cause, and to determine if this perspective matched the corrective action approach taken by the licensee to resolve the reported problems. These problems, along with planned and taken corrective actions, were discussed with the RP Manager.

b. Findings

No findings of significance were identified.

.7 RPT Proficiency

a. Inspection Scope

During job performance observations, the inspectors evaluated RPT performance with respect to RP work requirements and evaluated whether they were aware of the radiological conditions in their workplace, the RWP controls and limits in place, and if their performance was consistent with their training and qualifications with respect to the radiological hazards and work activities.

Radiological problem reports which found that the cause of the event was RPT error were reviewed to determine if there was an observable pattern traceable to a similar cause, and to determine if this perspective matched the corrective action approach taken by the licensee to resolve the reported problems.

b. Findings

No findings of significance were identified.

2OS2 ALARA Planning And Controls (71121.02)

.1 Inspection Planning

a. Inspection Scope

The inspectors reviewed plant collective exposure history, current exposure trends, ongoing and planned activities in order to assess current performance and exposure challenges. This included determining the plants current 3-year rolling average collective exposure in order to help establish resource allocation and to provide a perspective of significance for any resulting inspection finding assessment.

The inspectors reviewed the outage work scheduled during the inspection period, and associated work activity exposure estimates, including the five work activities which were likely to result in the highest personnel collective exposures. Site specific trends in collective exposures and source-term measurements were determined. Procedures associated with maintaining occupational exposures, ALARA and processes used to estimate and track work activity specific exposures were reviewed.

b. Findings

No findings of significance were identified.

.2 Radiological Work Planning

a. Inspection Scope

The inspectors evaluated the licensees list of work activities ranked by estimated exposure that were in progress and selected the five work activities of highest exposure significance using the following criteria:

  • The inspectors reviewed the ALARA work activity evaluations, exposure estimates, and exposure mitigation requirements in order to verify that the licensee had established procedures, and engineering and work controls that were based on sound RP principles in order to achieve occupational exposures that were ALARA. This also involved determining that the licensee had reasonably grouped the radiological work into work activities, based on historical precedence, industry norms, and/or special circumstances.
  • The inspectors compared the results achieved, including dose rate reductions and person-rem used, with the intended dose established in the licensees ALARA planning for these work activities. Reasons for inconsistencies between intended and actual work activity doses were reviewed. The interfaces between operations, RP, maintenance, maintenance planning, scheduling and engineering groups, were evaluated to identify interface problems or missing program elements. The integration of ALARA requirements into work procedure and RWP documents was evaluated to verify that the licensees radiological job planning would reduce dose.
  • The inspectors compared the person-hour estimates, provided by maintenance planning and other groups to the RP group, with the actual work activity time requirements, in order to evaluate the accuracy of these time estimates.

Shielding requests from the RP group were evaluated with respect to dose rate reduction along with engineering shielding responses follow up. The inspectors evaluated if work activity planning included consideration of the benefits of dose rate reduction activities, such as shielding provided by water filled components/piping, job scheduling, and shielding and scaffolding installation and removal activities. The licensees post-job (work activity) reviews were evaluated to verity that identified problems were entered into the licensees corrective action program.

b. Findings

No findings of significance were identified.

.3 Verification of Dose Estimates and Exposure Tracking Systems

a. Inspection Scope

The inspectors reviewed the assumptions and bases for the current annual collective exposure estimate including procedures, in order to evaluate the licensees methodology for estimating work activity-specific exposures and the intended dose outcome. Dose rate and man-hour estimates were evaluated for reasonable accuracy.

The licensees process for adjusting exposure estimates or re-planning work, when unexpected changes in scope, emergent work or higher than anticipated radiation levels were encountered, was evaluated. This included determining that adjustments to estimated exposure (intended dose) were based on sound RP and ALARA principles and not adjusted to account for failures to control the work. The frequency of these adjustments was reviewed to evaluate the adequacy of the original ALARA planning process.

The licensees exposure tracking system was evaluated to determine whether the level of exposure tracking detail, exposure report timeliness, and exposure report distribution was sufficient to support control of collective exposures. RWPs were reviewed to determine if they covered too many work activities to allow work activity specific exposure trends to be detected and controlled. During the conduct of exposure significant work, the inspectors evaluated if licensee management was aware of the exposure status of the work and would intervene if exposure trends increased beyond exposure estimates.

b. Findings

No findings of significance were identified.

.4 Job Site Inspections and ALARA Control

a. Inspection Scope

The inspectors selected five work activities in radiation areas, airborne radioactivity areas, or HRAs for observation, emphasizing work activities that presented the greatest radiological risk to workers. Jobs that were expected to result in the highest collective doses were observed and included diving activities in the spent fuel pool, and work in areas that involved potentially changing or deteriorating radiological conditions. The licensees use of ALARA controls for these work activities was evaluated using the following:

  • The licensees use of engineering controls to achieve dose reductions was evaluated to verify that procedures and controls were consistent with the licensees ALARA reviews, that sufficient shielding of radiation sources was provided for, and that the dose expended to install/remove the shielding did not exceed the dose reduction benefits afforded by the shielding.
  • Job sites were observed to determine if workers were utilizing the low dose waiting areas and were effective in maintaining their doses ALARA by moving to the low dose waiting area when subjected to temporary work delays.
  • The inspectors attended work briefings and observed ongoing work activities to determine if workers received appropriate on-the-job supervision to ensure the ALARA requirements were met. This included verification that the first-line job supervisor ensured that the work activity was conducted in a dose efficient manner by minimizing work crew size, ensuring that workers were properly trained, and that proper tools and equipment were available when the job started.
  • Exposures of individuals from selected work groups were reviewed to evaluate any significant exposure variations which could exist among workers, and to determine whether these significant exposure variations were the result of worker job skill differences, or whether certain workers received higher doses because of poor ALARA work practices.

b. Findings

No findings of significance were identified.

.5 Radiation Worker Performance

a. Inspection Scope

Radiation worker and RPT performance was observed during work activities being performed in radiation areas, airborne radioactivity areas, and HRAs that presented the greatest radiological risk to workers. The inspectors evaluated whether workers demonstrated the ALARA philosophy in practice by being familiar with the work activity scope and tools to be used, by utilizing ALARA low dose waiting areas, and that work activity controls were being complied with. Also, radiation worker training and skill levels were reviewed to determine if they were sufficient relative to the radiological hazards and the work involved.

b. Findings

No findings of significance were identified.

.6 Problem Identification and Resolution

The inspectors reviewed the licensees self-assessments, audits, and Special Reports related to the ALARA program since the last inspection, to determine if the licensees overall audit programs scope and frequency for all applicable areas under the Occupational Cornerstone met the requirements of 10 CFR 20.1101(c).

The inspectors verified that identified problems were entered into the corrective action program for resolution, and that they had been properly characterized, prioritized, and resolved. This included dose significant post-job (work activity) reviews and post-outage ALARA report critiques of exposure performance.

Corrective action reports related to the ALARA program were reviewed and staff members were interviewed to verify that follow-up activities had been conducted in an effective and timely manner commensurate with their importance to safety and risk using the following criteria:

  • initial problem identification, characterization, and tracking;
  • disposition of operability/reportability issues;
  • evaluation of safety significance/risk and priority for resolution;
  • identification of repetitive problems;
  • identification of contributing causes;
  • identification and implementation of effective corrective actions;
  • resolution of NCVs tracked in the corrective action system; and
  • Implementation/consideration of risk significant operational experience feedback The licensees corrective action program was also reviewed to determine if repetitive deficiencies and/or significant individual deficiencies in problem identification and resolution had been addressed.

b. Findings

No findings of significance were identified.

OTHER ACTIVITIES (OA)

4OA1 Performance Indicator (PI) Verification

Cornerstones: Initiating Events and Mitigating Systems

a. Inspection Scope

The inspectors reviewed reported first quarter 2003 data for unplanned power changes and heat removal system unavailability, PIs using the definitions, and guidance contained in Nuclear Energy Institute (NEI) 99-02, Regulatory Assessment Indicator Guideline, Revision 2. The inspectors reviewed station logs, event notification reports, licensee event reports, CRs, and TS logs to verify the accuracy of the licensees data submission.

b. Findings

No findings of significance were identified.

4OA2 Identification and Resolution of Problems

.1 Routine Review of Identification and Resolution of Problems

a. Inspection Scope

From April 14 through April 15, the inspectors performed a review of a sample of inservice inspection related problems that were identified by the licensee and entered into the corrective action program. The inspectors conducted this review in an office on the second floor of Maintenance Building 100 within the site protected area. The inspectors reviewed these corrective action program documents to confirm that the licensee had appropriately described the scope of the problems. Additionally, the inspectors review included confirmation that the licensee had an appropriate threshold for identifying issues and had implemented effective corrective actions. The inspectors performed these reviews to ensure compliance with 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, requirements. The specific corrective action documents that were reviewed by the inspectors are listed in the attachment to this report.

b. Findings

No findings of significance were identified.

.2 Annual Sample Review

a. Inspection Scope

During RFO9, licensee personnel identified a condition where contractor personnel removed and detorqued bolts for a CDRM that was not scheduled for work. The inspectors reviewed the associated CR and root cause for the event. In addition, the inspectors performed a walkdown of the subject CRDM, interviewed key personnel and reviewed applicable procedures.

b. Findings

The inspectors concluded that the root cause performed on the event identified a reasonable set of apparent causes. However, one of the causes, contractor oversight, was an area of emphasis prior to the outage. This event represents an instance where the corrective actions associated with improving contractor oversight failed to prevent recurrence of contractor related problems. In addition, the corrective actions associated with the event may be too narrowly focused on under vessel activities, thus limiting the effectiveness of the corrective actions.

4OA3 Event Followup

a. Inspection Scope

The inspectors observed control room personnel responding to FHB radiation and evacuation alarms received after an irradiated fuel rod was inadvertently damaged during licensee inspection activities on April 24. The inspectors arrived in the control room within minutes of the event and observed the follow-up actions by the licensee including operator briefings, monitoring of plant conditions, completion of required ONI actions, and emergency plan review. The inspectors reviewed the licensees emergency plan to verify the event was appropriately characterized as an Alert and that notification of county, state, and federal agencies occurred in a timely manner. As part of the event follow-up, the inspectors observed plant chart recorders, compared requirements of ONIs with observed licensee performance, and reviewed personnel statements from both control room and FHB personnel.

Although the activation of the licensees technical support center was not procedurally required due to the Alert entry conditions dissipating rapidly as radiation levels quickly returned to normal levels, the licensee chose to staff the facility to assist in the development of a recovery plan. The inspectors observed technical support center personnel performance to verify adequacy of communications and compliance with administrative problem solving procedures.

b. Findings

Following declaration of an Alert on April 24, the inspectors identified that the licensee failed to classify the Alert within 15 minutes. This was identified as an Unresolved Item (URI) pending determination whether any violation of NRC requirements occurred, and a determination as to the significance, if any violation is determined to have occurred.

At about 11:00 a.m. on April 24, a fuel pin broke on the fuel handling floor during inspection activities. Shortly thereafter, the FHB Gaseous Radiation Monitor sounded.

The licensee evacuated the FHB, drywell, and containment areas in response to the alarm and entered their Off-Normal Instruction for Fuel Handling Accidents. Initially, control room personnel were unaware of the cause of the alarm and the personnel they had been in contact with on the fuel handling floor were not aware of the damaged fuel pin. Between 11:20 a.m. and 11:30 a.m., a senior reactor operator (SRO) supporting the shift manager (SM) confirmed that a fuel pin had been broken. Using the Emergency Plan, the SRO determined that the entry conditions for an Alert had been met. At 11:30 a.m. and after another SRO had reviewed and endorsed his conclusion, the SRO informed the SM that a fuel pin had been broken and the conditions were satisfied for entry into an alert classification. While the SRO was reviewing entry conditions for an Alert, the FHB radiation alarm had cleared. At 11:50 a.m. the SM declared an Alert and immediately exited the Alert because radiation levels had returned to normal and the fuel pin had been placed in a safe configuration, i.e the conditions for an Alert were no longer met. The inspectors concluded that the event classification took at least 20 minutes which appeared to exceed the 15-minute goal of the licensees emergency plan.

This issue was considered an URI pending review by region based specialists.

Appendix B of IMC 0609 stipulates that findings will not be issued for Emergency Action Level classifications in excess of 15 minutes if the delay occurred because of activities necessary to protect the health and safety of the public. The region based specialists need to evaluate the event and make this determination. Once the determination is made, the safety significance must be determined in accordance with IMC 0609.

Pending completion of these activities, the issue is considered an URI (URI 50-440/03-04-04). The licensee has entered this issue into their corrective action program as CR 03-02408.

4OA5 Other Activities

A self-revealed violation of TS 5.4 occurred on May 7, when the licensed operator at-the-controls left the at-the-controls and operations area of the control room without using the appropriate procedure for shift and relief turnover.

On May 7, shortly before 4:40 a.m., two licensed operators conducted a temporary relief turnover for the at-the-controls position. At approximately 4:40 a.m., the licensed operator who had assumed the at-the-controls position left the at-the-controls and operations area of the control room for approximately 20 seconds to obtain initials from an instrumentation and control technician on a fuse replacement checklist. During the individuals absence, a control room annunciator was received. When the alarm was not acknowledged, two licensed operators who were also in the at-the-controls area (conducting an EDG surveillance run) observed the at-the-controls operators absence and one responded to the annunciator. The annunciator was expected due to operation of the inclined fuel transfer system. The at-the-controls operator returned to the at-the-controls area and completed a temporary relief turnover with the original at-the-controls operator a few minutes later. The operator who had left the at-the-controls area completed his shift and departed the site. The operator did not inform the supervisory SRO of the event prior to departing the site. The other two operators in the area, conducting the EDG run, did not inform the supervising SRO since they assumed the at-the-controls operator would. Operations management was not made aware of the personnel error until approximately 16.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> later at which time a condition report was generated and the individual was relieved of licensed operator duties pending incident review and remediation.

The inspectors determined that failing to perform a shift turnover prior to leaving the at-the-controls area represented a performance deficiency necessitating a significance evaluation. The inspectors applied the criteria in IMC 0612, Power Reactor Inspection Reports, Appendix B, Issue Disposition Screening, and concluded that the finding was greater than minor because it can reasonably be viewed as a precursor to a significant event. Operators are relied upon, in part, to detect and respond to changing plant conditions and serve to both prevent accidents and mitigate the effects of accidents should one occur. In other circumstances, a second licensed operator may not be in the control room and the alarm condition may not have been expected. Additionally, the failure to promptly identify a performance deficiency was not consistent with site expectations. The finding is of very low safety significance because the annunciator was expected due to inclined fuel transfer system operation and the licensed operator was out of the at-the-controls area for only approximately 20 seconds.

The performance deficiency associated with this event was the failure to follow procedures for shift and relief turnover. TS 5.4 required implementation of procedures required by Regulatory Guide 1.33. Regulatory Guide 1.33 required procedures for shift and relief turnover. The licensee developed PAP-0126, Shift Staffing and Shift Relief, Rev. 2, for shift staffing and shift relief and this procedure included instructions for relief of the licensed operator at-the-controls including temporary reliefs. Contrary to TS 5.4 requirements, this procedure was not used prior to the licensed operator at-the-controls leaving the at-the-controls and operations area of the control room on May 7. As a result, a control room annunciator was not acknowledged until another licensed operator, fortuitously in the at-the-controls area for another evolution, responded to the annunciator. The licensee entered this finding into the corrective action program (CR 03-03032). Because of the very low safety significance and because the issue has been entered into the licensees corrective action program, it is being treated as a NCV, consistent with Section VI.A.1 of the NRC Enforcement Policy (NCV 50-440/03-04-05).

4OA6 Meetings

.1 Exit Meeting

The inspectors presented the inspection results to Mr. T. Rausch, General Manager, and other members of licensee management at the conclusion of the inspection on June 27. The inspectors asked the licensee whether any materials examined during the inspection should be considered proprietary. No proprietary information was identified.

.2 Interim Exit Meetings

  • Inservice Inspection IP 71111.08 with Mr. W. Kanda on April 23;
  • Emergency Preparedness inspection with Mr. D. Bauguess on June 17; C Access Control and ALARA with Mr. W. Kanda and Mr. T. Rausch on April 17 and June 12; and telephone discussion with Mr. R. Coad on July 1.

4OA7 Licensee-Identified Violations

The following violation of very low safety significance (Green) was identified by the licensee and was a violation of NRC requirements which met the criteria of Section VI of the NRC Enforcement Policy, NUREG-1600, for being dispositioned a NCV.

C TS 5.4 requires that procedures be developed and implemented for repair and replacement of control rod drives. Contrary to these requirements, the licensee failed to follow procedures for repair and replacement of CRDMs. Specifically, the licensee removed six of eight bolts and detorqued the remaining two bolts for CRDM 22-35, even though this CRDM was not in the scope for repair or replacement. The licensee discovered that these bolts were removed while working on an unrelated repair of local power range monitor. Following detection of the missing bolts, the licensee suspended core alterations and replaced the missing bolts and CRDMs gasket. Had the licensee not detected the missing bolts, the potential existed for the CRDM to leak at power. Because the licensee detected the missing bolts while still in Mode 5 and corrected the deficiency, the inspectors considered this violation to be of very low safety significance.
