SUBJECT:
FERMI, UNIT 2 NRC INTEGRATED INSPECTION REPORT 50-341/03-006
Dear Mr. OConnor:
On June 30, 2003, the U.S. Nuclear Regulatory Commission (NRC) completed an integrated inspection at your Enrico Fermi, Unit 2. The enclosed report documents inspection findings which were discussed on July 11, 2003, with you, Mr. Cobb, and other members of your staff.
The findings were also discussed with S. Stasek and others on July 22, 2003.
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.
This report documents three self-revealing findings and one inspector identified finding of very low safety significance (Green). Three of these issues were determined to involve violations of NRC requirements. However, because of the very low safety significance and because they were entered into your corrective action program, the NRC is treating these issues as Non-Cited Violations (NCV) consistent with Section VI.A of the NRC Enforcement Policy.
If you contest any NCV in this report, 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 copies to the Regional Administrator, Region III; the Director, Office of Enforcement, U.S. Nuclear Regulatory Commission, Washington DC 20555-0001; and to the Resident Inspector at the Fermi 2 Nuclear Power Plant.
W. OConnor, Jr. -2-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 Fermi were completed on February 28, 2003. The NRC will continue to monitor overall safeguards and security controls at Fermi.
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 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).

Station. Maintenance Risk Assessments and Emergent Work Evaluation, Post Maintenance Testing, Surveillance Testing, Radioactive Material Control Program, Event Followup.
This report covers a 3-month period of baseline resident inspection and announced baseline inspections on April 11 and May 22, 2003. The inspection was conducted by regional inspectors and the resident inspectors. Four Green findings were identified. The significance of most findings is indicated by their color (Green, White, Yellow, Red) using Inspection Manual 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 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.
A. Inspection Findings
Cornerstone: Initiating Events
- Green.
A self revealed finding was identified for inappropriate maintenance on the breaker for the west station air compressor on December 20, 1999. This led to excessive cycling of the breaker and failure of the compressor coupling during compressor shutdown on March 13, 2003. This issue was considered more than minor because it affected an attribute and objective of the Initiating Events Cornerstone. No violation of regulatory requirements occurred because the issue occurred on plant support equipment, which was nonsafety-related.
A phase 2 risk assessment was performed and it was determined that the issue had low safety significance (Green) due to a low initiating event frequency of a Loss of Instrument Air with one of three station air compressors unavailable. (Section 1R19)
- Green.
The inspectors identified a Non-Cited Violation for failing to comply with 10 CFR 50.71(e). This violation was related to not updating the Updated Safety Analysis Report (USAR) with the effects of a safety analysis and evaluation performed by the licensee in support of approved license amendment 114, which allowed average reactor coolant system temperature to be between 200 and 212 degrees Fahrenheit for conducting in-service leakage tests and hydrostatic tests while in Mode 4. Specifically the licensees safety analysis and evaluation credited all control rods as fully inserted to ensure additional shutdown margin during these testing evolutions, but this condition (all rods inserted) was not incorporated into the USAR or licensee procedures.
This finding was more than minor because this condition permitted the conduct of control rod scram testing during hydrostatic and system leakage testing, which was different from the initial condition that all control rods were fully inserted as assumed in the analysis and evaluation for approved license amendment 114. The licensee provided this initial condition in their amendment request and the NRC staff used this initial condition in the safety evaluation for approval of license amendment 114. The failure to comply with 10 CFR 50.71(e) caused inappropriate pressure testing procedure changes and created a situation where less shutdown margin than originally evaluated and accepted by the NRC staff was present at times when these activities were conducted concurrently. As such, the performance of scram time testing during hydrostatic or system leakage testing would have required prior NRC approval in accordance with 10 CFR 50.59. The issue was considered of very low safety significance because the finding did not contribute to the likelihood of a primary or secondary system loss of coolant accident, it did not contribute to both the likelihood of a reactor trip and the likelihood that mitigation equipment or functions will not be available nor did it increase the likelihood of a fire or internal/external flood. Adequate shutdown margin had always been maintained. (Section R22)
- Green.
A self-revealed violation of 10 CFR 50, Appendix B, Criterion V, occurred on April 28, 2003, when operators improperly shifted reactor protection system busses and caused a loss of shutdown cooling. 10 CFR 50, Appendix B, requires, in part, that activities affecting quality shall be accomplished in accordance with prescribed procedures. The licensee developed Procedure 23.316 to shift reactor protection system busses and require depression of the open pushbutton for E1150-F008.
Contrary to these requirements, the operator failed to depress the pushbutton and caused a loss of shutdown cooling.
The inspectors determined that the violation is more than minor using the guidance provided in NRC Inspection Manual Chapters 0609 and 0612. Chapter 0609 provides guidance on evaluation of the significance of findings for a shutdown reactor. In accordance with Appendix G, Table 1 of 0609, loss of shutdown cooling is a finding of very low safety significance (Green). (Section 4AO3)
Cornerstone: Public Radiation Safety
- Green.
A self-revealing violation of 10 CFR 20.1802 was identified, when the licensee failed to maintain control of a measurable amount of licensed radioactive material (i.e., external radioactive contamination on a lanyard) identified during whole body counting of a contractor.
The finding was more than minor because it was associated with the Program and Process and Human Performance attributes of the Public Radiation Safety Cornerstone and affected the cornerstone objective in ensuring adequate protection of public health and safety from exposure to radioactive materials released into the public domain. The whole body count vendor operators apparent lack of knowledge as to the requirements to control measurable amounts of radioactive material, which was exacerbated by less than adequate radiation protection oversight of the vendor and procedure deficiencies, led to the unrestricted release of measurable radioactive material. However, this finding, associated with the licensees radioactive material control program, was of very low safety significance in that public radiation exposure was not greater than 0.005 rem and the licensee did not have more than five radioactive material control occurrences (in the previous 8 quarters). An associated Non-Cited Violation of 10 CFR 20.1802 was identified for the failure to control licensed radioactive material in an unrestricted area and not in storage. (Section 2PS3)
Licensee-Identified Violations
Violations of very low safety significance, which were identified by the licensee have been reviewed by the inspectors. Corrective actions taken or planned by the licensee have been entered into the licensees corrective action program. These violations and corrective action tracking numbers are listed in Section 40A7 of this report.
REPORT DETAILS
Summary of Plant Status
At the beginning of the inspection, the plant was shutdown during a planned refueling outage (RF09). At the conclusion of the outage, operators commenced an orderly plant startup. The reactor was critical on May 7, 2003 at 12:28 p.m. Startup continued and the plant entered Mode 1 on May 9, 2003 at 4:17 p.m. On May 14, 2003, the plant reached 100 percent power where it remained at or near for the duration of the inspection except for two pre-planned down powers to approximately 75 percent for rod pattern adjustments on May 19, 2003 and May 30,

The inspectors also verified that the impact of the testing had been properly characterized in the risk assessment, the test was performed as written, the testing prerequisites were satisfied, and that the test data was complete. Following the completion of the test, the inspectors verified that the system was returned to its normal standby configuration.
b. Findings
No findings of significance were identified.
.2 Post Maintenance Testing of the West Station Air Compressor
a. Inspection Scope
The inspectors reviewed control room logs, work requests, and CARDs, and interviewed system engineering and operations personnel to understand the circumstances surrounding the failure of the west station air compressor that occurred during post maintenance testing.
b. Findings
Introduction:
A Green finding was identified for conducting inappropriate maintenance on the breaker for the west station air compressor that led to excessive cycling of the breaker and failure of the compressor coupling during compressor shutdown, an issue considered greater than minor because it affected the Initiating Events Cornerstone.
Description:
Breaker 72A-3D refurbishment on the west station air compressor was performed on December 20, 1999, under Work Request V298960311. During that activity, maintenance personnel installed an incorrect breaker primary closing spring (Asea Brown Boveri Part Number No. 50402B vice Part No. 650216A11). The correct spring was stronger and had fewer coils. The incorrect spring size would prevent the breaker from remaining closed to provide power to the compressor motor. Instead, the breaker would cycle open and close, thereby interrupting power to the motor.
On October 22, 2002, during shutdown of west station air compressor P5001D003, the breaker cycled on and off several times, the coordinated manual control switch light flickered and the ammeter oscillated between 0 and 200 amps. Condition Assessment Resolution Document 02-16323 was initiated for tracking purposes only, meaning that no work requests were generated to repair the problem. Again on November 9, 2002, the breaker began cycling and CARD 02-16378 was written to address this condition.
Following this event, the licensee decided to place the west station air compressor on non-preferred use, meaning that operations personnel would select either the center or the east station air compressor to operate the station air system. Planners initiated Work Request 0000Z023462 to correct the condition. Troubleshooting proceeded under that work request and, on February 26, 2003, breaker cycling occurred again. Attempts to resolve the problem were unsuccessful because on March 13, 2003, during a post maintenance test run, the west station air compressor motor began sparking, smoking and glowing red on the portion of the shaft that enters the motor housing. The compressor was immediately shut down and investigation into the failure was started under CARD 03-00203.
A visual inspection was conducted on the coupling where the licensee discovered a crack. Upon disassembly, the licensee noticed severe torque induced damage on the compressor shaft. The licensee contacted and discussed the results of their investigation with the vendor, Centac. The licensee determined that the most probable cause of the coupling failure and shaft damage was the breaker cycling.
An induction motor is used to operate the compressor and stored internal voltage is characteristic of this type of motor. If the motor is restarted before the internal voltage has dissipated, the resultant large voltage can cause a corresponding coupling torque 20 times the rated design value. Centac Operation and Maintenance Notes 11-96 provided examples of sheared couplings, shafts or gearing as worst case examples while twisted pinions and detached impellers occurred during momentary power loss, such as during a breaker cycling. The licensee determined that the incorrect spring size, installed in December of 1999, was the cause of the breaker cycling condition.
The correct spring was installed and the compressor was tested satisfactorily.
Corrective actions to the CARD included addressing this issue in electrical maintenance training and inspecting breakers removed in RF09 for correct closing spring sizes.
Analysis:
The inspectors determined that the finding was a performance deficiency because maintenance personnel installed the incorrect primary closing spring during breaker 72A-3D refurbishment for the west station air compressor. The finding was greater than minor because it affected an attribute and objective of the Initiating Events Cornerstone in that the error resulted in the ultimate failure of the west station air compressor. Updated Final Safety Analysis Report Section 9.3.1.3, Safety Evaluation, states that maximum plant availability and control air system reliability are ensured by providing three station air compressors. In addition, if left uncorrected, this finding could result in a more significant safety concern (i.e., a plant transient).
During SDP Phase 1 screening of the issue, the inspectors determined that one less compressor incrementally increased the likelihood of an initiating event and that the failed compressor contributed to the likelihood of unavailable mitigating equipment.
Using the current risk-informed inspection notebook for Fermi 2 (Revision 0) for the Phase 2 SDP analysis, the inspectors determined that this finding was potentially greater than very low safety significance. Specifically, the inspectors determined that this issue caused the likelihood for transients involving a loss of the compressed air system to be increased by an order of magnitude using Usage Rule 1.3 of IMC 0609, Appendix A, Attachment 2.
The initiating event likelihood was evaluated for a greater than 30-day period because the condition had existed since December 1999. However, after a review of additional information, the inspectors determined that a Phase 3 analysis was required. As a result, the inspectors requested assistance in determining risk from the NRC Regional Senior Reactor Analyst (SRA). The SRA informed the inspectors of a refinement to the Fermi 2 SDP notebooks based on a recent bench marking trip the SRA conducted at Fermi in April 2003. During that trip, the SRA recognized that the loss of one of three compressors for an indefinite period represented a low initiating event frequency of a Loss of Instrument Air and, therefore, this issue was considered of low safety significance and a Green finding (FIN 50-341/2003-06-01).
Enforcement:
No violation of regulatory requirements occurred. The inspectors determined that the finding did not represent a non-compliance because it occurred on nonsafety-related, plant support equipment.
1R20 Refueling and Outage
a. Inspection Scope
The inspectors observed control room activities associated with the shutdown for the scheduled refueling outage including removing equipment from service, inserting control rods, completing mode specific surveillance testing, and monitoring reactor coolant temperature. The inspectors attended daily outage meetings, reviewed outage control center and control room operator logs, and conducted daily control room tours to ensure that shutdown safety was maintained throughout the outage, reactor coolant system instrumentation provided accurate information, the decay heat removal systems were functioning properly, and inventory and reactivity controls were maintained. The inspectors conducted periodic observations of outage related work activities to ensure that work activities were performed in accordance with plant procedures. The inspectors performed tours of the Turbine Building, Reactor Building, and Drywell to verify that procedural requirements regarding fire protection, foreign material exclusion, and the storage of equipment near safety-related structures, systems, and components were maintained. The inspectors observed refueling activities to verify that the licensee adhered to established procedures and Technical Specification requirements for handling of irradiated fuel. The inspectors verified that the licensee maintained secondary containment in accordance with Technical Specification requirements.
The following major activities were observed or performed:
- Fuel bundle oriented incorrectly in Spent Fuel Pool, CARD 03-12015
- The inspectors reviewed the licensees restart restraint process and verified closure of selected issues. Issues reviewed included the RHR reservoir service water pumps bolt and column degradation and the gasket material (foreign material intrusion) identified in the reactor pressure vessel
- Routine drywell tours
- Attended Outage Planning Meetings
- Verified Defense-in-Depth for shutdown cooling
- Refueling Operations
- Drywell closeout Inspection
- Verified Shutdown Cooling Tagouts
- Verified Completion of Restart Restraint Items
b. Findings
No findings of significance were identified.
1R22 Surveillance Testing
.1 Routine Surveillance Testing
a. Inspection Scope
The inspectors observed surveillance testing or reviewed test data for risk-significant systems or components to assess compliance with Technical Specifications, 10 CFR 50, Appendix B, and licensee procedure requirements. The testing was also evaluated for consistency with the UFSAR. The inspectors verified that the testing demonstrated that the systems were ready to perform their intended safety functions. The inspectors reviewed whether test control was properly coordinated with the control room and performed in the sequence specified in the surveillance instruction, and if test equipment was properly calibrated and installed to support the surveillance tests. The procedures reviewed are listed in the attached List of Documents Reviewed. The specific surveillance activities assessed were:
C Reactor pressure vessel hydrostatic and system leakage test
- EDG 11 slow start surveillance test
b. Findings
No findings of significance were identified.
.2 Scram Timing Tests Conducted During Reactor Pressure Vessel Leakage Test
a. Inspection Scope
The inspectors questioned the acceptability of conducting control rod scram time tests during system leakage test of the reactor pressure vessel with average reactor coolant temperatures above 200 degrees Fahrenheit. The inspectors interviewed operations and licensing personnel and the staff from the office of Nuclear Reactor Regulation to understand whether moving control rods with reactor pressure vessel temperatures elevated above 200 degrees Fahrenheit was acceptable. To aid in the issue disposition, the inspectors reviewed the Code of Federal Regulations, Improved Technical Specifications and associated amendment requests and Bases and Amendment 114 to Special Operations Technical Specification 3/4.10.7, Hydrostatic Leak Test.
b. Findings
Introduction A Green NCV was identified for the failure to comply with 10 CFR 50.71(e) related to not updating the Updated Safety Analysis Report (USAR) with the effects of a safety analysis and evaluation performed by the licensee in support of an approved license amendment (License Amendment 114), which allowed average reactor coolant system temperature to be between 200 and 212 degrees Fahrenheit for conducting inservice leak tests and hydrostatic tests while in Mode 4. Specifically the licensees safety analysis and evaluation credited all control rods as fully inserted during these testing evolutions; however, the licensee did not keep all control rods fully inserted, but performed control rod scram time testing during the period when reactor coolant temperature was above 200 degrees.
Description:
On September 5, 1997, the licensee requested (as noted in Letter NRC-97-0107) a special test exception to allow in-service leak testing and hydrostatic testing to be performed at temperatures greater than 200 degrees Fahrenheit but less than or equal to 212 degrees Fahrenheit in Mode 4. Mode 4 is defined in Technical Specifications, in part, as average reactor coolant temperature less than or equal to 200 degrees Fahrenheit. The next higher mode, Mode 3, was defined, in part, as average reactor coolant temperature greater than 200 degrees Fahrenheit. This request was considered an exigent Technical Specification change to support an October 3, 1997, mid-cycle outage to replace a leaking fuel assembly.
2, No Significant Hazards Consideration, of Letter NRC-97-0107 stated that hydrostatic testing at temperatures between 200 and 212 degrees Fahrenheit will not significantly increase the probability of an accident previously evaluated due, in part, to all control rods fully inserted and nearly water-solid conditions. Therefore, the stored energy in the reactor core coolant would be very low and the potential for causing fuel failures with a subsequent increase in coolant activity was minimal. On September 30, 1997, the NRC issued Amendment 114, to change Technical Specification 3/4.10.7. In the Safety Evaluation, the staff agreed that permitting the average reactor coolant temperature to be between 200 and 212 degrees Fahrenheit while performing the leak test would not substantially affect the results of potential accidents that may occur with the average reactor coolant temperature since the hydrostatic leak tests are performed near water solid and with all control rods inserted.
The change was implemented but the associated Technical Specification Bases were not changed to state the rods would be inserted during the leakage tests.
Procedure 43.000.009, Reactor Pressure Vessel System Leakage Test, was used by the licensee to satisfy the pressure test and it was revised on October 13, 1997, allowing the test to be performed at temperatures between 200 and 212 degrees Fahrenheit. Nevertheless, step 5.1.2 of Procedure 43.000.009 provided the option of conducting Procedure 54.000.003, Control Rod Scram Insert Time Test, during the leakage test. Allowing scram timing tests to be performed contradicted the analysis statement that the test was performed with all control rods fully inserted as described in 2 of Letter NRC-97-0107. However, during the October 1997 outage, operators conducted the leakage test under Infrequently Performed Test or Evolution 97-05 where operators raised reactor coolant system temperature between 200 and 212 degrees Fahrenheit and scram time tests were not performed.
The licensee did not revise the USAR with the effect of the safety analysis/evaluation that supported license amendment 114. Consequently, since this information was not in the USAR, the information was not available while preparing new Procedure 24.137.21,Reactor Pressure Vessel System Leakage Test, which replaced Procedure 43.000.009. Step 5.1.2 of Procedure 24.137.21 also permitted scram time testing of the control rods even though the licensing basis for TS 3/4.10.7 specified that all control rods would be fully inserted with reactor pressure vessel temperature between 200 and 212 degrees Fahrenheit during the hydrostatic test.
Between 1998 and 1999, the licensee began to convert current Technical Specifications to Improved Technical Specifications. While evaluating the less restrictive changes to Technical Specifications 3/4.10.7, the special operations specification in improved Technical Specifications 3/4.10.1, Inservice Leak and Hydrostatic Testing Operation, did not restrict the hydrostatic test temperature to a maximum of 212 degrees Fahrenheit, and this restriction was removed The condition that the control rods be fully inserted during hydrostatic testing as specified in Amendment 114 was not specifically evaluated while processing amendment 134, for the technical specification conversion.
Since all subsequent revisions to Procedure 24.137.21 allowed scram timing tests to be performed during the reactor pressure vessel leakage test, and the improved Technical Specification bases did not specify a restriction that all control rods were inserted during hydrostatic testing, operators potentially continued to perform scram time testing at average reactor coolant temperatures greater than 200 degrees Fahrenheit since 1998.
Recently, operators conducted scram time testing above 200 degrees Fahrenheit during Refueling Outage 9. Given the existence of amendment 114, the inspectors challenged the acceptability of performing the scram timing test during the hydro test at temperatures greater than 200 degrees Fahrenheit. On July 9, 2003, the licensee initiated CARD 03-11742 to document the inspectors questions.
Analysis:
This finding was greater than minor because this condition allowed a procedure change that permitted the conduct of control rod scram testing (i.e., withdrawal of selected control rods) concurrent with operation under the provisions of Technical Specification 3/4.10.7, that would have otherwise required prior NRC approval in accordance with 10 CFR 50.59. The conduct of control rod scram testing concurrent with operation under the provisions of Technical Specification 3/4.10.7 impacts the equipment lineup (inserted reactivity) assumed as the initial condition for a safety analysis/evaluation for an approved license amendment. This initial condition (all rods fully inserted) was credited in the licensees application for amendment 114 and the NRC staff safety evaluation documenting approval of the license amendment 114.
The failure to comply with 10 CFR 50.71(e) and the resultant inappropriate procedure change created a situation where less shutdown margin than originally evaluated and accepted by the NRC staff was present when these activities (control rod testing and hydrostatic testing) were conducted concurrently. Thus this finding affects the Initiating Events Cornerstone of the Reactor Safety Strategic Performance Area. Using Phase 1 of Manual Chapter 0609, Significance Determination Process, Appendix A, 1, the inspectors determined this issue was of very low significance (Green)because the finding did not contribute to the likelihood of a primary or secondary system loss of coolant accident, does not contribute to both the likelihood of a reactor trip and the likelihood that mitigation equipment or functions will not be available nor increase the likelihood of a fire or internal/external flood.
Enforcement:
10 CFR 50.71(e) states, in part, that the licensee shall revise the USAR to include the effects of all safety evaluations performed by the licensee either in support of requested license amendments or in support of conclusions that changes did not involve an unreviewed safety question. Contrary to the above, the licensee failed to revise the USAR with the effects of a safety analysis and evaluation in support of approved license amendment 114, which allowed average reactor coolant system temperature to be between 200 and 212 degrees Fahrenheit for conducting in-service leakage tests and hydrostatic tests while in Mode 4, Technical Specification 3/4.10.7.
Specifically the licensees safety analysis and evaluation credited all control rods as fully inserted during these testing evolutions. Because the failure to revise the USAR with this information is of very low safety significance and has been entered into the licensee corrective action program (CARD 03-11742), this violation is being treated as an NCV, consistent with Section VI.A of the NRC Enforcement Policy (NCV 50-341/2003-006-02).

.1 Plant Walkdowns, Radiological Boundary Verification, and Radiation Work Permit
(RWP) Reviews
a. Inspection Scope
The inspectors reviewed the stations implementation of physical and administrative controls over access to radiologically restricted areas, including worker adherence to these controls, by reviewing station procedures, RWPs, electronic dosimetry alarm set points, and walking down radiologically significant areas (radiation areas, high radiation areas (HRAs), and locked HRAs) of the station. Specifically, areas in the Reactor Building (including the Drywell and Steam Tunnel), Turbine Building, and On-Site Storage Facility were observed to verify these areas were posted and controlled in accordance with 10 CFR Part 20, licensee procedures, and Technical Specifications.
The inspectors also reviewed RWPs with the potential for internal dose assignments of 50 millirem committed effective dose equivalent or more, to assess the appropriateness of engineering controls employed to minimize dose. Through day 14 of RF09, the licensee had not assigned any internal dose greater than 50 millirem committed effective dose equivalent. Therefore, the inspectors reviewed licensee tracking reports and assessed the adequacy of internal dose assessments for two personal contamination events resulting from under vessel control rod drive replacement activities.
b. Findings
No findings of significance were identified.
.2 Identification and Resolution of Problems
a. Inspection Scope
The inspectors reviewed CARDs completed in conjunction with the refueling outage which focused on access control to radiologically significant areas, radiation worker practices, and radiation protection (RP) technician practices. The inspectors reviewed these documents to assess the licensees ability to identify repetitive problems, contributing causes, the extent of conditions, and implement corrective actions intended to achieve lasting results.

2OS2 As-Low-As-Is-Reasonably-Achievable (ALARA) Planning and Controls (71121.02)
.1 Radiological Work/ALARA Planning
a. Inspection Scope
The inspectors reviewed the stations procedures for radiological work/ALARA planning and scheduling, and evaluated the dose projection methodologies and practices implemented for the RF09 refueling outage, to verify that sound technical bases for outage dose estimates existed. Specifically, the inspectors reviewed radiologically significant (i.e., collective dose estimates of 5.0 person-rem or greater) RWP/ALARA planning packages, including:
- Control Rod Drive Exchange (RWP No. 03-1117)
- In-Service Inspections (RWP No. 03-1112)
- Insulation Removal, Repair, and Replacement (RWP No. 03-1110)
- Install and Remove Scaffold, Power, and Lights in Drywell and Steam Tunnel (RWP No. 03-1105)
- Install and Remove Temporary Shielding and Install Permanent Shielding in Drywell (RWP No. 03-1103)
- Perform Refuel Activities on Reactor Building Level 5 (RWP No. 03-1251)
- E11FO50A and E11FO50B - Perform Softseat Replacement in lieu of Hardseat Modifications (RWP No. 03-1127)
The inspectors reviewed these seven radiologically significant RWP/ALARA planning packages to verify that adequate person-hour estimates, job history files, lessons learned, industry experiences, and the use of mockups (where applicable) were utilized in the ALARA planning process and to confirm that these elements were integrated into the associated RWPs.
b. Findings
No findings of significance were identified.
.2 Job Site Inspections and ALARA Controls
a. Inspection Scope
The inspectors observed work activities in the radiologically restricted areas that were performed in radiation areas, HRAs, and locked HRAs to evaluate the use of ALARA controls. Specifically, the inspectors reviewed radiological surveys, attended pre-job radiological briefings, and assessed job site ALARA controls, at least in part, for the following work activities:
- Control Rod Drive replacement (RWP No. 03-1117)
C Inspection of the East Main Steam Reheater (RWP No. 03-1207)
C Removal of the Main Steam Bypass Valve and transfer to the rebuild area (RWP No. 03-1207)
C In-vessel visual inspection of the Control Rod Drive blades on Reactor Building Level 5 (RWP No. 03-1251)
C Traversing In-Core Probe room entry for explosive valve detonation and replacement, fire detector operability/sensitivity test, and visual inspection of penetrations (RWP No. 03-1152)
Worker instruction requirements, including protective clothing, engineering controls to minimize dose exposures, the use of predetermined low dose waiting areas, as well as the on-the-job supervision by the work crew leaders and RP technicians, were observed to determine if the licensee had maintained the radiological exposure for these work activities ALARA. Enhanced job controls including RP technician use of electronic teledosimetry and cameras was also evaluated to assess the licensees ability to maintain real-time doses ALARA in the field. Additionally, the inspectors observed the implementation of dosimetry placement changes necessitated by significant dose rate gradients under the reactor vessel during control rod drive replacement activities (per the requirements of RWP No. 03-1117).
b. Findings
No findings of significance were identified.
.3 Radiation Worker/RP Technician Performance
a. Inspection Scope
The inspectors observed radiation workers performing the activities described in Section 2OS2.2 and evaluated their awareness of radiological conditions, personal electronic dosimetry alarm set points, and their implementation of applicable radiological controls. Additionally, the inspectors observed RP technician control over these work activities to evaluate if the technicians were aware of the radiological conditions in their workplace, the RWP controls/limits in place for the work activities, and that they appropriately communicated any significant changes in radiological conditions to the workers whose activities they were overseeing.
b. Findings
No findings of significance were identified.
.4 Verification of Dose Estimates, Dose Trending, and Dose Tracking Systems
a. Inspection Scope
The inspectors reviewed the licensees total outage dose estimates, selected individual job dose estimates and the related dose trending for the refueling outage. As of April 9, 2003, (day 12 of an estimated 29 day outage), the licensee had recorded a collective dose of 57.965 person-rem compared to the estimate of 66.500 person-rem for that point in RF09 (and a total estimate of 110.000 person-rem for the outage). The inspectors reviewed and discussed with RP staff the scope change for RWP 03-1127 (50A/50B valve seat modification), and associated re-evaluation of the ALARA plan, to evaluate the licensees ability to assess the effectiveness of an ALARA plan in a timely manner and institute changes in the plan or its execution, as warranted. The licensees dose tracking system was also reviewed to determine if the level of dose tracking detail, dose report timeliness, and report distribution were sufficient to support the control of collective and individual dose for the outage.
b. Findings
No findings of significance were identified.
.5 Identification and Resolution of Problems
a. Inspection Scope
The inspectors reviewed licensee CARDs completed in conjunction with the RF09 outage which focused on ALARA planning and controls. The inspectors additionally reviewed a recent Nuclear Quality Assurance Audit of the RP program (focusing on Nuclear Quality Assurances review of ALARA planning and controls).

2PS3 Radioactive Material Control Program (71122.03)
Review of an Unrestricted Release of Radioactive Material Occurrence During Contractor Whole Body Counting In-processing
a. Inspection Scope
The inspectors reviewed the circumstances associated with the unrestricted release of low-level radioactive material (i.e., external contamination on a lanyard) that occurred on March 20, 2003, following whole body counting of contractors as part of their station in-processing. Specifically, the inspectors reviewed the licensees initial CARD, investigative documents (including worker statements and a time line of the event),whole body count and survey data, and the incident was discussed with the radiation protection manager and several members of the RP staff.
b. Findings
Introduction:
A self-revealing Green finding and an associated Non-Cited Violation (NCV) were identified for the failure to maintain control of a measurable amount of radioactive material (i.e., external radioactive contamination on a lanyard) identified during whole body counting of contractors during station in-processing.
Description:
On March 20, 2003, a whole body count vendor operator was conducting whole body counting of contract personnel as part of their station in-processing in the General Training and Orientation Center (GTOC). The GTOC is located outside of the stations Protected Area but is within the Owner Controlled Area (OCA) of the station.
At approximately 11:39 a.m., the first contract individual was identified as having a positive whole body count (WBC) with Mn-54, Co-58, and Cs-137 (6.3 nanocuries (nCi),6.4 nCi, and 2.4 nCi, respectively). The vendor operator instructed the contractor to remove his lanyard and conducted a second WBC which was negative for the presence of measurable radioactivity. Subsequently, the vendor operator returned the lanyard to the contractor with the instructions that ...he discard the old lanyard, since it may be mildly contaminated. At approximately 12:12 p.m., a second contractors WBC was positive for the presence of radioactivity (approximately 9.8 nCi Co-60). The vendor operator had the contractor remove his fleece vest and repeated the WBC. The follow-up WBC was negative for the presence of measurable radioactivity, and, similarly, the vendor operator returned the fleece vest to the contractor with a suggestion that he launder the vest. At approximately 1:59 p.m., a third contractors WBC indicated possible positive activity with a 143 keV peak. The contractor indicated that his boots may have been previously contaminated, thus the vendor operator performed another WBC of the contractor with his boots removed; the follow-up WBC was negative for the presence of measurable radioactivity.
This event was self-revealing when, at approximately 2:15 p.m., the RP Instrument Supervisor and a principle radiological engineer went out to the GTOC to check on the vendor operator and they were subsequently informed about the recent positive WBCs and apparent external contaminations. The RP Instrument Supervisor initiated an investigation and was able to take control of the contaminated materials/clothing from two of the individuals who were still within the OCA by approximately 5:30 p.m.
However, the first contractor had apparently left the OCA with the externally contaminated lanyard. Radiation Protection management was able to contact the first contractor later that evening; the contractor indicated that he was still in possession of the lanyard, and RP management requested that he place the lanyard in a bag and bring it into the station the following morning (March 21, 2003). However, when the contractor returned the lanyard to the station, follow-up surveys and gamma spectroscopic analyses could not identify the radioactive material on the lanyard, in the contractors automobile, or in the bag and briefcase the contractor said he had placed the lanyard in overnight. Extensive licensee surveys of the WBC room and the GTOC did not identify any additional detectable radioactive material.
The licensees investigation revealed that the vendor operator was apparently not cognizant of the procedural and regulatory requirements to take control of any measurable radioactive material outside of the radiologically restricted areas. The licensee additionally identified that there was less than adequate vendor oversight by the RP department and procedure deficiencies which contributed to the occurrence.
Analysis:
The inspectors determined that the issue was associated with the Program and Process and Human Performance attributes of the Public Radiation Safety Cornerstone and affected the cornerstone objective in ensuring adequate protection of public health and safety from exposure to radioactive materials released into the public domain. Also, the issue involved an occurrence in the licensees radioactive material control program that is contrary to both NRC regulations and licensee procedures.
Therefore, the issue was more than minor and represents a finding which was evaluated using the significance determination process (SDP) for the Public Radiation Safety Cornerstone.
The inspectors determined that the vendor operators apparent lack of knowledge as to the requirements to control measurable amounts of radioactive material, which was exacerbated by less than adequate RP oversight of the vendor and procedure deficiencies, led to the unrestricted release of measurable radioactive material into the public domain (outside the OCA). As such, the inspectors determined utilizing Manual Chapter 0609, Appendix D, Public Radiation Safety SDP, that the finding involved radioactive material control, but transportation was not involved. Additionally, public radiation exposure was not greater than 0.005 rem (5 millirem) and the licensee did not have more than five radioactive material control occurrences (in the previous 8 quarters). Consequently, the inspectors concluded that the SDP assessment for this finding was of very low safety significance (Green).
Enforcement:
Title 10 CFR 20.1802 requires that the licensee shall control and maintain constant surveillance of licensed material that is in a controlled or unrestricted area and that is not in storage. On March 20, 2003, the licensee failed to maintain control of a measurable amount of licensed radioactive material (i.e., external radioactive contamination on a lanyard) identified during whole body counting of a contractor. This failure constitutes a violation of 10 CFR 20.1802. However, because the licensee documented this issue in its corrective action program (CARD 03-00690) and because the violation is of very low safety significance, it is being treated as an NCV (NCV 50-341/03-006-03).

4OA2 Identification and Resolution of Problems
.1 Review of Identification and Resolution of Problems for Inservice Inspection Related
Issues
a. Inspection Scope
From April 7, 2003 through April 11, 2003, 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 in an on-site office on the second floor of the Availability Improvement Building 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 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

b. Findings
(Closed) LER 50-341/02-005-00: Non-Conservative Setpoint for Stability Option III (OPRM) Period Based Algorithm.
On November 21, 2002, the General Electric Company informed the licensee that the stability Option III period based detection algorithm range for minimum period detection (Tmin) values may be non-conservative. General Electric recommended that the average power range monitor, oscillation power range monitor (OPRM) upscale trip (Technical Specification Limiting Condition for Operation 3.3.1.1, Function 2.f) be considered inoperable for plants with Tmin set at greater than 1.2 seconds. The licensee had Tmin set at 1.4 seconds so their OPRMs were declared inoperable.
General Electrics 10 CFR Part 21 Notification concerning this issue states, With Tmin set to 1.2 seconds or lower, the OPRM is considered to be operable. Additionally, the report also provided guidance on the setting of the maximum period detection (Tmax)value, stating, The OPRM is considered operable for values of Tmax set to 3.0 seconds or higher. At the time, the licensee had Tmax set at 3.0 seconds.
Technical Service Request 32279 was initiated to change the OPRM Tmin and Tmax values to 1.2 and 1.4, respectively for all four OPRMs. Work requests 000Z023654, 000Z023657, 000Z023658, and 000Z023659 were performed to make the necessary changes. The inspectors verified that the setpoints were changed, as required, on all OPRMs. The LER was reviewed by the inspectors and no findings of significance were identified. The licensee documented this issue in CARD 02-18019. This LER is closed.
.2 Momentary Loss of Shutdown Cooling
a. Inspection Scope
On April 28, 2003, the inspectors evaluated the control room staff response to a loss of shutdown cooling due to operator error. The inspectors observed plant parameters and operator activities associated with restoration of decay heat removal. The inspectors reviewed operations logs and interviewed operators to understand the circumstances surrounding the unexpected momentary loss of shutdown cooling.
b. Findings
Introduction:
A self-revealed Green NCV was identified for failure to comply with 10 CFR 50, Appendix B, Criterion V, related to operators failing to depress the open push button for E1150-F008, the RHR Outboard Suction Isolation Valve, when restoring Reactor Protection System (RPS) B power. As a result of this failure, the valve closed when RPS B power was restored and the plant lost shutdown cooling.
Description:
On April 28, 2003, the licensee was restoring RPS B in accordance with Procedure 23.316. During the power restoration process, the outboard RHR insolation valve would close unless the valves open button was depressed prior to power restoration. Contrary to the procedural instruction, the operator failed to depress the open button and the valve closed as designed. The valve isolated the suction flow path for RHR thus causing a loss of the shutdown cooling. The licensee recognized the loss of shutdown cooling and restored decay heat removal within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />.
Analysis:
The performance deficiency associated with this event was the failure to follow procedures for shifting RPS busses. The inspectors compared this finding to those listed in Appendix E of Manual Chapter 0612 and concluded it most closely matched Item 4.b and was more than minor because it caused a plant transient - loss of shutdown cooling. The inspectors compared the finding to Appendix G of NRC Inspection Manual 0609 and concluded that finding screened as Green. This finding identified a loss of shutdown cooling. However, Appendix G does not require a quantitative analysis for loss of shutdown cooling for the plant conditions of greater than 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> to boil. The finding is of very low safety significance (Green) based on the guidance of Appendix G.
Enforcement:
10 CFR 50, Appendix B, requires, that activities affecting quality shall be prescribed by documented instructions, procedures or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures or drawings. The licensee developed Procedure 23.316 to shift RPS busses and it required depression of the open pushbutton for E1150-F008. Contrary to these requirements, the operator failed to depress the pushbutton and caused a loss of shutdown cooling. The licensee entered this finding into the corrective action program (CARD 03-17206). 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 50-341/03-006-04).
4OA5 Other
The inspectors reviewed the final report for the March 18, 2003, Plant Evaluation performed by an inspection team from the Institute of Nuclear Power Operations. No further inspection was deemed necessary by NRC inspectors, and no assessment was made of the results of the inspection.
4OA6 Meetings
.1 Exit Meeting
The inspectors presented the inspection results to Mr. OConnor and other members of licensee management at the conclusion of the inspection on July 11, 2003. The inspectors asked the licensee whether any material examined during the inspection should be considered proprietary. No proprietary information was identified.
.2 Interim Exit Meetings
Interim exits were conducted for:
- Radiation Protection inspection with Mr. Cobb on April 11, 2003.
C Inservice Inspection with Mr. OConnor on April 11, 2003.
C Safeguards inspection with Mr. S. Peterman on May 22, 2003.
.3 Re-Exit Meeting
The inspectors reviewed the inspection findings with S. Stasek and others to communicate final characterization of the issues. The meeting was held on July 22, 2203.
4OA7 Licensee-Identified Violations
The following violations of very low significance were identified by the licensee and are violations of NRC requirements which meet the criteria of Section VI of the NRC Enforcement Manual, NUREG-1600, for being dispositioned as NCVs.
C Technical Specification 3.6.1.3 requires that a primary containment penetration be isolated within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />, if the associated primary containment isolation valve is not operable. Contrary to this, on March 19, 2003, a drywell floor drain sump outboard containment isolation valve was inoperable, and the penetration was not isolated within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />. This was identified in the licensees Corrective Action Program as CARD 03-11287. This finding is of very low safety significance because it does not represent an open pathway in the physical integrity of the reactor containment.
C 10 CFR 50, Appendix B, Criterion V, requires procedures for activities affecting quality. Contrary to this, on March 5, 2003, no procedures were established to prevent insulators from removing a small amount of insulation from Divisions 1 and 2 RHR heat exchanger piping while the plant was at power, thereby affecting the environmental qualification of pot-accident sampling system containment isolation valves. This condition existed for 14 days. This was identified in the licensees Corrective Action Program as Condition Assessment Resolution Document 03-14848. This finding is of very low safety significance because of the small amount of insulation removed, the low probability of design basis accident occurring while the insulation was removed and no impact on valve operability.
C 10 CFR 50, Appendix B, Criterion XVI, requires that measures be established to assure that conditions adverse to quality are promptly identified and corrected.
Contrary to this requirement, licensee inspections of the residual heat removal (RHR) reservoir on April 5, 2003, as a part of corrective actions to the failure of bolts on the number 2 circulating water pump, identified that adequate inspections had not been established in the RHR reservoir to identify and prevent micro biologically induced corrosion that degraded bolts, fasteners and welds on both divisions of service water pump suction columns at the ultimate heat sink. The conditions causing slow degradation of components had been developing for the life of the plant. This issue was identified in the licensees Corrective Action Program as CARD 03-14451. This finding is of very low safety significance because, although some degradation had begun on all ten service water pumps in the reservoir, no actual loss of safety function occurred for any of the pumps.
