SUMMARY OF FINDINGS
IR 05000285/2009005; 10/31/2009 - 12/31/2009; Fort Calhoun Station, Integrated Resident and Regional Report; Access Control to Radiologically Significant Areas.
The report covered a 3-month period of inspection by resident inspectors and two announced baseline inspections by regional based inspectors. One Green noncited violation of significance was identified. The significance of most findings is indicated by their color (Green, White, Yellow, or Red) using Inspection Manual Chapter 0609, "Significance Determination Process." Findings for which the significance determination process 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 4, dated December 2006.
A. NRC-Identified Findings and Self-Revealing Findings
- Green.
The inspectors identified a noncited violation of 10 CFR 19.12 for failure to provide adequate instruction to declared pregnant workers. Specifically, the licensee did not provide adequate information concerning the potential health protection problems and risk associated with exposure of an embryo/fetus to radiation and/or radioactive materials. The licensee entered this issue into their corrective action program as Condition Report CR 2009-5854.
The inspectors determined that the failure to provide adequate instruction to declared pregnant workers is a performance deficiency. The finding is more than minor because it is associated with the occupational radiation safety cornerstone attribute and adversely affects the objective to ensure adequate protection of worker health and safety from exposure to radiation during routine civilian nuclear reactor operation. Using the Occupational Radiation Safety Significance Determination Process, the inspectors determined this finding to be of very low safety significance because the finding did not involve ALARA planning and work controls, did not result in an overexposure, did not present a substantial potential for overexposure, and did not compromise the licensee's ability to assess dose. Additionally, the finding had a crosscutting aspect in the area of human performance, resources component, because the licensee failed to ensure the procedures related to declared pregnant workers included adequate instructions concerning the increased health concerns related to radiation exposure to the embryo/fetus H.2(c) (Section 2OS2).
B. 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 licensee's corrective action program. These violations and condition report numbers are listed in Section 4OA7.
REPORT DETAILS
Summary of Plant Status
The unit began this inspection period in Mode 1 at full rated thermal power and operated at approximately 100 percent until October 31, 2009. On November 1, 2009, the plant was shutdown for Refueling Outage number 25. On December 18, 2009, reactor criticality was achieved. The main generator was synched to the grid on December 20, 2009, and reactor power was raised to approximately 30 percent to stabilize secondary chemistry. Power ascension was halted at 49 percent power due to a steam leak in MS-475 (High Pressure Turbine Instrument Tap Root Valve) on December 21, 2009. Power was reduced to approximately 8 percent and the turbine was taken offline to repair MS-475. Following repairs to MS-475, the main generator was again synched to the grid on December 22, 2009. Reactor power was steadily raised to 66 percent on December 23, 2009. The unit returned to 100 percent power on December 29, 2009, and remained at that power level for the remainder of the inspection period.
REACTOR SAFETY
Cornerstones: Initiating Events, Mitigating Systems, Barrier Integrity, and Emergency Preparedness
1R04 Equipment Alignments
.1 Partial Walkdown
a. Inspection Scope
The inspectors performed partial system walkdowns of the following risk-significant systems:
- December 18, 2009, Portions of the emergency diesel generators prior to the plant's transition to mode 2
- December 29, 2009, Portions of the low pressure safety injection system The inspectors selected these systems based on their risk significance relative to the Reactor Safety Cornerstones at the time they were inspected. The inspectors attempted to identify any discrepancies that could affect the function of the system, and, therefore, potentially increase risk. The inspectors reviewed applicable operating procedures, system diagrams, Updated Safety Analysis Report, technical specification requirements, administrative technical specifications, outstanding work orders, condition reports, and the impact of ongoing work activities on redundant trains of equipment in order to identify conditions that could have rendered the systems incapable of performing their intended functions. The inspectors also inspected accessible portions of the systems to verify system components and support equipment were aligned correctly and operable. The inspectors examined the material condition of the components and observed operating parameters of equipment to verify that there were no obvious deficiencies. The inspectors also verified that the licensee had properly identified and resolved equipment alignment problems that could cause initiating events or impact the capability of mitigating systems or barriers and entered them into the corrective action program with the appropriate significance characterization. Specific documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of two partial system walkdown samples as defined in Inspection Procedure 71111.04-05.
b. Findings
No findings of significance were identified.
1R05 Fire Protection

- Verifying appropriate performance criteria for structures, systems, and components classified as having an adequate demonstration of performance through preventive maintenance, as described in 10 CFR 50.65(a)(2), or as requiring the establishment of appropriate and adequate goals and corrective actions for systems classified as not having adequate performance, as described in 10 CFR 50.65(a)(1)
The inspectors assessed performance issues with respect to the reliability, availability, and condition monitoring of the system. In addition, the inspectors verified maintenance effectiveness issues were entered into the corrective action program with the appropriate significance characterization. Specific documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of two quarterly maintenance effectiveness samples as defined in Inspection Procedure 71111.12-05.
b. Findings
No findings of significance were identified.
1R13 Maintenance Risk Assessments and Emergent Work Control
a. Inspection Scope
The inspectors reviewed licensee personnel's evaluation and management of plant risk for the maintenance and emergent work activities affecting risk-significant and safety-related equipment listed below to verify that the appropriate risk assessments were performed prior to removing equipment for work:
- October 19, 2009, Orange risk activity associated with the auxiliary building fire header being out of service
- November 3, 2009, Compensatory measures associated with loss of one channel of reactor vessel level indication The inspectors selected these activities based on potential risk significance relative to the reactor safety cornerstones. As applicable for each activity, the inspectors verified that licensee personnel performed risk assessments as required by 10 CFR 50.65(a)(4)and that the assessments were accurate and complete. When licensee personnel performed emergent work, the inspectors verified that the licensee personnel promptly assessed and managed plant risk. The inspectors reviewed the scope of maintenance work, discussed the results of the assessment with the licensee's probabilistic risk analyst or shift technical advisor, and verified plant conditions were consistent with the risk assessment. The inspectors also reviewed the technical specification requirements and inspected portions of redundant safety systems, when applicable, to verify risk analysis assumptions were valid and applicable requirements were met. Specific documents reviewed during this inspection are listed in the attachment.
These activities constitute completion of two maintenance risk assessments and emergent work control inspection samples as defined in Inspection Procedure 71111.13-05.

b. Findings
Introduction.
The inspectors identified a Green noncited violation of 10 CFR 19.12 for failure to provide adequate instruction to declared pregnant workers. Specifically, the licensee did not provide adequate information concerning the potential health protection problems and risk associated with exposure of the embryo/fetus to radiation and/or radioactive materials.
Description.
During a review of the licensee's declared pregnant worker program, the inspectors noted that the licensee's program did not contain sufficient guidance to properly inform the declared pregnant worker of the additional health problems associated with radiation exposure to the embryo/fetus. The form utilized by the licensee required the individual to state they were declaring either their pregnancy or their anticipated pregnancy. At that point, the individual would sign the form and an investigative whole body count would be performed. The form would then be forwarded to a dosimetry technician who would enter the appropriate administrative exposure limits into the computer. The form did not have a requirement to ensure the worker was aware of the reduced radiation exposure limits and potential risks to the embryo/fetus. The licensee indicated that they did not specifically brief the worker on the potential risk of radiation exposure to the embryo/fetus at the time of the pregnancy declaration.
Analysis.
The inspectors determined that the failure to provide adequate instruction to declared pregnant workers is a performance deficiency. The finding is more than minor because it is associated with the Occupational Radiation Safety Cornerstone attribute and adversely affects the objective to ensure adequate protection of worker health and safety from exposure to radiation during routine civilian nuclear reactor operation. Using the Occupational Radiation Safety Significance Determination Process, the inspectors determined this finding to be of very low safety significance because the finding did not involve ALARA planning and work controls, did not result in an overexposure, did not present a substantial potential for overexposure, and did not compromise the licensee's ability to assess dose. Additionally, the finding had a crosscutting aspect in the area of human performance, resources component, because the licensee failed to ensure the procedures related to declared pregnant workers included adequate instructions concerning the increased health concerns related to radiation exposure to the embryo/fetus H.2(c).
Enforcement.
Title 10 CFR 19.12.a(2), states that all individuals who in the course of employment are likely to receive in a year an occupational dose in excess of 100 millirem shall be instructed in the health protection problems associated with exposure to radiation and/or radioactive material. Contrary to the above, the licensee failed to provide sufficient instructions to declared pregnant workers. Instructions provided did not ensure the worker was aware of the increased sensitivity to radiation of the embryo/fetus, nor ensure the worker was aware of the decreased radiation limits during the time of the pregnancy. Because the finding is of very low safety significance and has been entered into the licensee's corrective action program as Condition Report 2009-5854, this violation is being treated as a noncited violation consistent with Section VI.A.1 of the NRC Enforcement Policy: NCV 0500285/2009005-01, "Failure to Provide Adequate Instruction to Pregnant Workers."
OTHER ACTIVITIES
4OA1 Performance Indicator Verification
.1 Data Submission Issue
a. Inspection Scope
The inspectors performed a review of the performance indicator data submitted by the licensee for the fourth Quarter 2009 performance indicators for any obvious inconsistencies prior to its public release in accordance with Inspection Manual Chapter 0608, "Performance Indicator Program."
This review was performed as part of the inspectors' normal plant status activities and, as such, did not constitute as a separate inspection sample.
b. Findings
No findings of significance were identified.
.16 Occupational Exposure Control Effectiveness (OR01)
a. Inspection Scope
The inspectors sampled licensee submittals for the occupational radiological occurrences performance indicator for the period from the fourth quarter 2008 through the third quarter 2009
. To determine the accuracy of the performance indicator data reported during those periods, performance indicator definitions and guidance contained in NEI Document 99-02, "Regulatory Assessment Performance Indicator Guideline," Revision 5, was used. The inspectors reviewed the licensee's assessment of the performance indicator for occupational radiation safety to determine if indicator related data was adequately assessed and reported. To assess the adequacy of the licensee's performance indicator data collection and analyses, the inspectors discussed with radiation protection staff, the scope and breadth of its data review, and the results of those reviews. The inspectors independently reviewed electronic dosimetry dose rate and accumulated dose alarm and dose reports and the dose assignments for any intakes that occurred during the time period reviewed to determine if there were potentially unrecognized occurrences. The inspectors also conducted walkdowns of numerous locked high and very high radiation area entrances to determine the adequacy of the controls in place for these areas.
These activities constitute completion of one sample of the occupational radiological occurrences as defined in Inspection Procedure 71151-05.
b. Findings
No findings of significance were identified.
.17 Radiological Effluent Technical Specifications/Offsite Dose Calculation Manual Radiological Effluent Occurrences (PR01)
a. Inspection Scope
The inspectors sampled licensee submittals for the Radiological Effluent Technical Specifications/Offsite Dose Calculation Manual Radiological Effluent Occurrences performance indicator for the period from the fourth quarter 2008 through the third quarter 2009. To determine the accuracy of the performance indicator data reported during those periods, performance indicator definitions and guidance contained in NEI Document 99-02, "Regulatory Assessment Performance Indicator Guideline," Revision 5, was used. The inspectors reviewed the licensee's issue report database and selected individual reports generated since this indicator was last reviewed to identify any potential occurrences such as unmonitored, uncontrolled, or improperly calculated effluent releases that may have impacted offsite dose. The inspectors reviewed gaseous effluent summary data and the results of associated offsite dose calculations for selected dates between the fourth quarter of 2008 through the third quarter of 2009 to determine if indicator results were accurately reported. The inspectors also reviewed the licensee's methods for quantifying gaseous and liquid effluents and determining effluent dose.
These activities constitute completion of one sample of the radiological effluent technical specifications/offsite dose calculation manual radiological effluent occurrences as defined in Inspection Procedure 71151-05.
b. Findings
No findings of significance were identified.
OA2 Identification and Resolution of Problems
Cornerstones: Initiating Events, Mitigating Systems, Barrier Integrity, Emergency Preparedness, Public Radiation Safety, Occupational Radiation Safety, and Physical Protection
.1 Routine Review of Identification and Resolution of Problems
a. Inspection Scope
As part of the various baseline inspection procedures discussed in previous sections of this report, the inspectors routinely reviewed issues during baseline inspection activities and plant status reviews to verify that they were being entered into the licensee's corrective action program at an appropriate threshold, that adequate attention was being given to timely corrective actions, and that adverse trends were identified and addressed. The inspectors reviewed attributes that included the complete and accurate identification of the problem; the timely correction, commensurate with the safety significance; the evaluation and disposition of performance issues, generic implications, common causes, contributing factors, root causes, extent of condition reviews, and previous occurrences reviews; and the classification, prioritization, focus, and timeliness of corrective actions. Minor issues entered into the licensee's corrective action program because of the inspectors' observations are included in the attached list of documents reviewed.
These routine reviews for the identification and resolution of problems did not constitute any additional inspection samples. Instead, by procedure, they were considered an integral part of the inspections performed during the quarter and documented in Section 1 of this report.
b. Findings
No findings of significance were identified.
.2 Daily Corrective Action Program Reviews
a. Inspection Scope
In order to assist with the identification of repetitive equipment failures and specific human performance issues for follow-up, the inspectors performed a daily screening of items entered into the licensee's corrective action program. The inspectors accomplished this through review of the station's daily corrective action documents.
The inspectors performed these daily reviews as part of their daily plant status monitoring activities and, as such, did not constitute any separate inspection samples.
b. Findings
No findings of significance were identified.
4OA3 Event Follow-up
.1 (Closed) LER 05000285/2009003-00, Void in Safety Injection Piping During Operation Due to Inadequate Procedural Guidance

These observations took place during both normal and off-normal plant working hours.
These quarterly resident inspector observations of security force personnel and activities did not constitute any additional inspection samples. Rather, they were considered an integral part of the inspectors' normal plant status review and inspection activities.
b. Findings
No findings of significance were identified.
.2 Temporary Instruction 2515/172, "Reactor Coolant System Dissimilar Butt Welds" (Closed)
Temporary Instruction 2515/172 was previously performed at Fort Calhoun Station in April 2008. The results of the previous inspections are documented in Inspection Report 05000285/2008003.
Following guidance of Temporary Instruction 2515/172, the inspectors have completed all NRC activities associated with this Temporary Instruction.
a. Licensee's Implementation of the Materials Reliability Program (MRP)-139 Baseline Inspection i. During Refueling Outage 24, in spring 2008, the licensee identified the existence of Alloy 82/182, nozzle-to-safe-end butt welds, in the reactor hot leg and cold leg nozzles. MRP-139 baseline inspections on the dissimilar metal butt welds were performed in the current Refueling Outage 25, November 2009. The inspectors reviewed the baseline inspections and verified that the inspections were completed in accordance to MRP-139. No relevant indications were identified during the inspection of the reactor hot leg and cold leg nozzles ii. Currently, the licensee is not planning to deviate from the requirements of MRP-139 and all future examinations are scheduled in accordance with this document.
b. Volumetric Examinations i. The inspectors reviewed the baseline ultrasonic examinations of the reactor hot leg and cold leg nozzles, as indicated in Section "IP 71111.08" of this report. The licensee determined that no relevant indications were identified during the examination.
ii. This item is not applicable because the licensee did not employ weld overlays.
iii. The certification records of ultrasonic examination personnel used in the examination were reviewed. All personnel records indicated that they were qualified under the Electric Power Research Institute Performance Demonstration Initiative.

On January 14, 2010, the inspectors presented the inspection results to Mr. T. Nellenbach, and other members of the licensee staff. The licensee acknowledged the issues presented. The inspector asked the licensee whether any materials examined during the inspection should be considered proprietary. No proprietary information was identified.
OA7 Licensee-Identified Violations The following violations of very low safety significance (Green) were identified by the licensee and are violations of NRC requirements which meet the criteria of Section VI of the NRC Enforcement Policy, NUREG-1600, for being dispositioned as NCVs.
.1 Technical Specifications 5.11.2 requires that locked doors shall be provided to prevent unauthorized entry into areas with radiation greater than 1000 millirem per hour and the keys shall be maintained under the administrative control of the Shift Manager and/or the Manager, Radiation Protection.
Contrary to this requirement, on November 13, 2009, a radiation protection technician inadvertently placed a key to the hand-hole covers of the 'B' steam generator into the trash receptacle when exiting the containment building. The key was found approximately two hours later. This was identified in the licensee's corrective action program as Condition Report 2009-5650. This finding is of very low safety significance because there was no indication that the key was used by unauthorized personnel to access the steam generator hand-holes.
.2 Technical Specification 5.8.1 requires the licensee to establish, maintain, and implement written procedures covering the applicable procedures recommended by Regulatory Guide 1.33, Revision 2, Appendix A, 1978.
Section 7.e(1) of Appendix A lists procedures for access control to radiation areas including a radiation work permit system. The licensee's Radiation Work Permit 09-2522, states that workers are to contact radiation protection for current survey data and a briefing prior to entering a posted high radiation area. Contrary to this requirement, on November 17, 2009, two workers were observed crossing a boundary to a high radiation area. When questioned about the briefing, the individuals stated they had not received a briefing for entry into the room. The individuals were excluded from entering the radiologically controlled area until interviews could be performed. This was indentified in the licensee's corrective action program as Condition Report 2009-5813. This finding is of very low safety significance because there was no overexposure, no potential for overexposure, and the licensee's ability to assess dose was not compromised.
.3 Title 10 CFR Part 50, Appendix B Criterion V, "Instructions, Procedures, and Drawings", states in part, "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."
Contrary to the above, the licensee failed to review and identify Safety Injection System high point vents during the development of the system drain and refill procedure. A resulting void in the high pressure safety injection pump SI-2B cooled suction line rendered SI-2B inoperable from approximately May 18, 2008 until April 30, 2009. This finding had very low safety significance because the alternate high pressure safety injection train SI-2A/2C was available during the period the gas void existed in the cooled suction piping to high pressure safety injection pump SI-2B. This finding was identified in the licensee's corrective action program as Condition Report 2009-2069 and was reported as LER 05000285/2009003-00.
