SUBJECT:
R.E. GINNA NUCLEAR POWER PLANT, LLC - NRC INTEGRATED INSPECTION REPORT 05000244/2013002
Dear Mr. Pacher:
On March 31, 2013, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your R.E. Ginna Nuclear Power Plant, LLC (Ginna). The enclosed inspection report documents the inspection results, which were discussed on April 12, 2013, with you 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.
This report documents one NRC-identified finding of very low safety significance (Green). This finding was determined to involve a violation of NRC requirements. However, because of the very low safety significance, and because it was entered into your corrective action program, the NRC is treating this finding as a non-cited violation (NCV), consistent with Section 2.3.2 of the NRC Enforcement Policy. If you contest the NCV in this report, you should provide a response within 30 days of the date of this inspection report, with the basis of your denial, to the Nuclear Regulatory Commission, ATTN.: Document Control Desk, Washington, DC 20555-0001; with copies to the Regional Administrator, Region I; the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Resident Inspector at Ginna. In accordance with 10 CFR 2.390 of the NRCs Rules of Practice, a copy of this letter, its enclosure, and your response (if any) will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records component of the NRCs Agencywide Documents Access Management System (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).
Sincerely,
/RA/

SUMMARY
IR 05000244/2013002; 01/01/2013 - 03/31/2013; R.E. Ginna Nuclear Power Plant, LLC (Ginna); Operability Determinations and Functionality Assessments.
This report covered a 3-month period of inspection by resident inspectors and announced inspections performed by regional inspectors. Inspectors identified one finding of very low safety significance (Green), which was a non-cited violation (NCV). A findings significance is indicated by a color (i.e., greater than Green, or Green, White, Yellow, Red) and determined using Inspection Manual Chapter (IMC) 0609, Significance Determination Process (SDP),
dated June 2, 2011. Cross-cutting aspects are determined using IMC 0310, Components Within Cross-Cutting Areas, dated October 28, 2011. All violations of NRC requirements are dispositioned in accordance with the NRCs Enforcement Policy, dated January 28, 2013. The NRCs program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process, Revision 4.
Cornerstone: Initiating Events
- Green.
The inspectors identified a NCV of Ginna Operating License Condition 2.C.(3), Fire Protection, for failure to implement and maintain in effect all fire protection features described in licensee submittals referenced in and as approved or modified by the NRCs Safety Evaluation Report, dated February 1979 and subsequent supplements. Specifically,
Constellation did not identify, account for, or evaluate 250 pounds of non-fire retardant treated plywood that has likely been installed in the screen house building (fire zone SH-2)since original construction and 434 pounds of other combustible material in the screen house. Immediate corrective actions included entering this issue into the corrective action program (CR-2013-001507 and CR-2013-001714). Additional planned corrective actions include revising the combustible loading analysis and replacing the installed plywood with a non-combustible material.
The inspectors determined that the failure to treat all wood with fire retardant and maintain its combustible loading analysis accurate and up-to-date was more than minor, because it was associated with the protection against external factors attribute of the Initiating Events cornerstone and affected the cornerstone objective to limit the likelihood of events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Specifically, Constellation did not identify non-fire retardant treated wood and accurately account for the amount of combustibles present in the screen house and was required to recalculate the areas combustible loading to assure the assumptions made in Ginnas exemption request from the technical requirements of Section III.G.3 of 10 CFR 50,
Appendix R, were still met. Additionally, this issue is similar to example 3I described in IMC 0612, Appendix E, Examples of Minor Issues. The inspectors evaluated the finding using IMC Attachment 0609.04, Initial Characterization of Findings, and IMC 0609 Appendix F,
Fire Protection Significance Determination Process, because the finding involved a failure to adequately implement fire prevention and administrative controls. A low degradation rating was assigned to this finding because the combustible loading of the screen house remained within its current LOW range, and the fire protection program element was expected to display nearly the same level of effectiveness as it would have without the degradation. Therefore, the inspectors determined the finding is of very low safety significance (Green). In accordance with IMC 0612, the finding does not have a cross-cutting aspect, because the performance deficiency likely occurred during original plant construction and is not reflective of present plant performance.

.3 Biennial Review
a. Inspection Scope
The following inspection activities were performed using NUREG-1021, "Operator Licensing Examination Standards for Power Reactors," Revision 9, Supplement 1, and Inspection Procedure Attachment 71111.11, Licensed Operator Requalification Program and Licensed Operator Performance.
Examination Results Requalification written exam results were reviewed to determine if pass/fail rates were consistent with the guidance of IMC 0609, Appendix I, Operator Requalification Human Performance Significance Determination Process. (Note: Annual requalification operating test results were previously reported in NRC Integrated Inspection Report 05000244/2012005.)
The review verified that the individual pass rate on the written examination was greater than 80 percent (pass rate was 100 percent).
More than 80 percent of the individuals passed all portions of the requalification exam (overall pass rate when combined with previously reported operating test results was 89.7 percent).
Written Examination and Operating Test Quality and Administration The inspectors reviewed a sample of comprehensive written exams that facility staff administered to the operators in January and February 2013.
The inspectors reviewed the operating test (three scenarios and six job performance measures [JPMs]) associated with the onsite inspection week and an additional operating test (three scenarios and four JPMs) associated with a subsequent examination week.
The inspectors observed facility training staff administer dynamic simulator exams and JPMs during the week of December 3, 2012. These observations included facility evaluations of crew and individual operator performance during the simulator exams and individual performance of JPMs.
The inspectors assessed whether facility staff properly safeguarded exam material, and whether test item repetition was excessive.
Remedial Training and Re-examinations The inspectors reviewed one remedial training package and its respective re-examination. This review was associated with an operator who had failed a written exam in February 2011.
Conformance with License Conditions The inspectors reviewed a sample of Ginna reactivation records and proficiency watch standing records to ensure that 10 CFR 55.53 license conditions and applicable program requirements were met. The inspectors also reviewed a sample of records for requalification training attendance and a sample of medical examinations for compliance with license conditions and NRC regulations.
Simulator Performance The inspectors reviewed simulator performance and fidelity for conformance to the reference plant control room. A sample of simulator deficiency reports was also reviewed to ensure facility staff addressed identified modeling problems.
Problem Identification and Resolution The inspectors reviewed recent operating history documentation found in inspection reports, licensee event reports, Ginnas CAP, and the most recent NRC plant issues matrix. The inspectors also reviewed specific events from Ginnas CAP which indicated possible training deficiencies to verify that they had been appropriately addressed. The NRC resident staff was also consulted for insights regarding licensed operators performance.
b. Findings
No findings were identified.
1R12 Maintenance Effectiveness
a. Inspection Scope
The inspectors reviewed the samples listed below to assess the effectiveness of maintenance activities on structure, system, and component (SSC) performance and reliability. The inspectors reviewed CAP documents and maintenance rule basis documents to ensure that Constellation was identifying and properly evaluating performance problems within the scope of the maintenance rule. For the samples selected, the inspectors verified that the SSCs were properly scoped into the maintenance rule in accordance with 10 CFR 50.65 and verified that the (a)(2)performance criteria established by Constellation staff was reasonable. As applicable, for SSCs classified as (a)(1), the inspectors assessed the adequacy of goals and corrective actions to return these SSCs to (a)(2). Additionally, the inspectors ensured that Constellation staff was identifying and addressing common cause failures that occurred within and across maintenance rule system boundaries.

1R13 Maintenance Risk Assessments and Emergent Work Control
a. Inspection Scope
The inspectors reviewed station evaluation and management of plant risk for the maintenance and emergent work activities listed below to verify that Constellation performed the appropriate risk assessments prior to removing equipment from service.
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 Constellation personnel performed risk assessments as required by 10 CFR 50.65(a)(4) and that the assessments were accurate and complete. When Constellation performed emergent work, the inspectors verified that operations personnel promptly assessed and managed plant risk. The inspectors reviewed the scope of maintenance work and discussed the results of the assessment with the stations probabilistic risk analyst to verify plant conditions were consistent with the risk assessment. The inspectors also reviewed the TS requirements and inspected portions of redundant safety systems, when applicable, to verify risk analysis assumptions were valid and applicable requirements were met.

1R15 Operability Determinations and Functionality Assessments
a. Inspection Scope
The inspectors reviewed operability determinations for the following degraded or non-conforming conditions:
B EDG lube oil (L/O) system low pressure on February 1, 2013 B EDG fuel oil system low pressure on February 4, 2013 B MFW pump leaking SW strainer to L/O cooler on February 15, 2013 Combustible loading analysis accounting for previously unidentified installed plywood in the screen house on March 1, 2013 Auxiliary building block walls not properly pinned on March 12, 2013 The inspectors selected these issues based on the risk significance of the associated components and systems. The inspectors evaluated the technical adequacy of the operability determinations to assess whether TS operability was properly justified and the subject component or system remained available such that no unrecognized increase in risk occurred. The inspectors compared the operability and design criteria in the appropriate sections of the TSs and UFSAR to Constellations evaluations to determine whether the components or systems were operable. Where compensatory measures were required to maintain operability, the inspectors determined whether the measures in place would function as intended and were properly controlled by Constellation. The inspectors determined, where appropriate, compliance with bounding limitations associated with the evaluations.
b. Findings
Introduction.
The inspectors identified a Green NCV of Ginna Operating License Condition 2.C.(3), Fire Protection, for failure to implement and maintain in effect all fire protection features described in licensee submittals referenced in and as approved or modified by the NRCs safety evaluation report, dated February 1979 and subsequent supplements. Specifically, Constellation did not identify, account for, or evaluate non-fire retardant treated plywood and other combustibles in the screen house building (fire zone SH-2). As a result, a credible fire scenario involving the identified combustibles could affect equipment important to safety and required a recalculation of the combustible loading analysis.
Description.
On March 1, 2013, the inspectors identified that several electrical panels were mounted on non-fire retardant plywood bases in the screen house; these plywood bases have likely been in place since the plant was originally constructed. The inspectors identified approximately 100 square feet of non-fire retardant treated 0.75-inch plywood, weighing approximately 230 pounds, which was not included in the combustible loading analysis for this fire area. This plywood has safety-related equipment mounted to itthe A and B screen house direct current (DC) distribution panels and the local SW pump selector switches. Both DC panels are large enough that they are considered ignition sources. Using its fire modeling database zone of influence calculator and assuming flame radiation for a 98th percentile heat release rate, Constellation determined that safety-related bus 18 could be impacted by the fire because of its close proximity to the identified plywood (within approximately 8 feet).
Constellation assumed that a fire affecting bus 18 would also affect safety-related bus 17, thereby impacting all four safety-related SW pumps. In addition to the two safety-related DC distribution panels, buses 17 and 18, and the four SW pumps, the motor-driven fire pump and the diesel-driven fire pump control panels could also be affected by this fire scenario. This fire could also cause a short to ground on the conductor in cables L0725 and L0472, which run into bus 18, and cause the normal supply breaker to safety-related bus 14, which contains breakers for emergency core cooling system equipment, to spuriously open.
EPM-FPPR, Ginna Station Fire Protection Program Report Volumes 1, 2 and 3, Revision 008.0 states, Administrative controls shall be established and maintained to minimize the amounts of combustibles that a safety-related/safe shutdown area may be exposed to. These controls shall governwood used in safety-related/safe shutdown areas to assure that it is treated with flame retardant, and lists DA-ME-98-004, Combustible Loading Analysis, Revision 010, dated May 21, 2012, as the evaluation used as part of the basis for Ginnas exemption from the technical requirements of Section III.G.3 of 10 CFR 50, Appendix R, which requires the installation of a complete area-wide fixed fire suppression system. Ginna evaluation DA-ME-98-004 assumed incorrect quantities of combustibles in its analysis of the screen house. Specifically, the calculation assumed 50 pounds of wood present in the screen house; approximately 583 pounds of wood and 101 pounds of other previously unidentified combustible materials were identified by the inspectors and Constellations extent-of-condition review. The combustible loading analysis had calculated a total combustible loading of 9,122 BTU/ft2 for the entire screen house building (fire area SH) and a total combustible loading of 8,841 BTU/ft2 for the screen house building operating floor (fire zone SH-2).
Based on the fire loading added by the wood and other identified materials, the final calculated total combustible loading increased to 9,525 BTU/ft2 for fire area SH and 9,440 BTU/ft2 for fire zone SH-2, which contained the majority of the previously unidentified combustibles. In accordance with EP-3-P-0132, Fire Protection Appendix R Conformance Verifications, Revision 00800, the combustible loading is still considered in the LOW range. Additionally, alternate shutdown capability that is independent of the fire area has been provided.
Immediate corrective actions included entering this issue into the CAP as CR-2013-001507 and CR-2013-001714. Additional planned corrective actions include revising DA-ME-98-004 and replacing the installed plywood with a non-combustible material.
Analysis.
The inspectors determined that Constellations failure to implement and maintain in effect all fire protection featuresspecifically, identifying and treating all wood with fire retardant and maintaining an accurate combustible loading analysis for fire zone SH-2was a performance deficiency that was within Constellations ability to foresee and correct and should have been prevented. The inspectors determined that the failure to treat all wood with fire retardant and maintain its combustible loading analysis accurate and up-to-date was more than minor, because it was associated with the protection against external factors attribute of the Initiating Events cornerstone and affected the cornerstone objective to limit the likelihood of events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Specifically, Constellation did not identify non-fire retardant treated wood and accurately account for the amount of combustibles present in the screen house and was required to recalculate the areas combustible loading to assure the assumptions made in Ginnas exemption request from the technical requirements of Section III.G.3 of 10 CFR 50, Appendix R, were still met. Additionally, this issue is similar to example 3I described in IMC 0612, Appendix E, Examples of Minor Issues. The inspectors evaluated the finding using the IMC Attachment 0609.04, Initial Characterization of Findings, Issued June 19, 2012. The attachment instructs the inspectors to utilize IMC 0609 Appendix F, Fire Protection Significance Determination Process, issued February 28, 2005, when the finding involves a failure to adequately implement fire prevention and administrative controls. A low degradation rating was assigned to this finding because the combustible loading of the screen house remained within its current LOW range, and the fire protection program element was expected to display nearly the same level of effectiveness as it would have without the degradation. Therefore, the inspectors determined the finding is of very low safety significance (Green).
In accordance with IMC 0612, the finding does not have a cross-cutting aspect because the performance deficiency likely occurred during original plant construction and is not reflective of present plant performance.
Enforcement.
Ginna Operating License Condition 2.C.(3), requires, in part, Constellation to implement and maintain in effect all fire protection features described in the licensees submittals referenced in and as approved or modified by the NRCs Fire Protection Safety Evaluation dated February 14, 1979, and safety evaluation supplements dated December 17, 1980, February 6, 1981, June 22, 1981, February 27, 1985, and March 21, 1985, or configurations subsequently approved by the NRC. EPM-FPPR, Ginna Station Fire Protection Program Report Volumes 1, 2 and 3, Revision 008.0, states, ensure all wood products are fire retardant treated, and lists DA-ME-98-004, Combustible Loading Analysis, Revision 010, dated May 21, 2012, as the evaluation used as part of the basis for Ginnas exemption from the technical requirements of Section III.G.3 of 10 CFR 50, Appendix R, which requires the installation of a complete area-wide fixed fire suppression system. Contrary to the above, for many years until March 2013, Constellation did not identify, account for, or evaluate 250 pounds of non-fire retardant treated plywood and 434 pounds of additional combustible material in the screen house building (fire zone SH-2). As a result, the combustible loading analysis for the area needed to be recalculated to assure assumptions made in Ginnas exemption request from the technical requirements of Section III.G.3 of 10 CFR 50, Appendix R, were still met. Immediate corrective actions included entering this issue into the CAP to evaluate replacing the installed plywood with a non-combustible material. Because this violation is of very low safety significance (Green), and Constellation entered this issue into their CAP (CR-2013-001507 and CR-2013-001714), this violation is being treated as an NCV consistent with Section 2.3.2 of the Enforcement Policy.

RADIATION SAFETY
Cornerstone: Public Radiation Safety and Occupational Radiation Safety
2RS1 Radiological Hazard Assessment and Exposure Controls
a. Inspection Scope
During the period March 11 to 14, 2013, the inspectors conducted the following activities to verify that Constellation was properly implementing physical, administrative, and engineering controls for access to locked high radiation areas and other radiological controlled areas (RCAs) during normal operations. Implementation of these controls was reviewed against the criteria contained in 10 CFR 20, relevant TSs, and Ginnas procedures.
Plant Walkdown and Radiation Work Permit (RWP) Reviews The inspectors toured accessible RCAs in the SG mausoleum, the intermediate building, auxiliary building, and various radwaste and contaminated equipment storage buildings.
Independent radiation surveys were performed on selected areas to confirm the accuracy of survey data and the adequacy of postings. Locked high radiation areas located in these areas were verified to be properly secured, posted, and monitored during plant tours.
The inspectors identified radiological-significant jobs scheduled to be performed in the RCAs. The inspectors reviewed the applicable RWPs, as low as reasonable achievable (ALARA) job reviews, and the electronic dosimeter dose and dose rate alarm set points for the associated tasks to determine if the radiological controls were acceptable and if the set points were consistent with plant policy. Jobs reviewed included cleaning of the A CCW HX (RWP 13-1/2), turbine building floor grinding (RWP 13-1/7), and installation of A and C charging pump motors (RWP 13-21). For the jobs reviewed, the inspectors determined if dosimetry was appropriately specified and properly located on the body and if air samples were taken for jobs that had the potential for generating airborne contamination; i.e., turbine building floor grinding (RWP 13-1/7).
The inspectors evaluated the effectiveness of contamination controls by touring work areas, reviewing survey data, and observing practices at various work locations in the auxiliary building, turbine building, and in contaminated material storage buildings.
Locked High Radiation Area Controls The inspectors reviewed procedures related to the control of high dose rate and locked high radiation areas. The inspectors discussed these procedures with radiation protection (RP) supervision to determine if any changes made to these procedures reduced safety measures.
Airborne Controls The inspectors reviewed the preparations made in response to possible changing radiological conditions in the turbine building which may have resulted from the floor grinding. The inspectors reviewed the preparations made for this task including installing tent containments, use of high-efficiency particulate air portable filtration systems, portal contamination monitors, and air samplers for work areas.
During plant tours, the inspectors verified that continuous air samplers were operating and located in areas where potential airborne contamination could occur.
Contamination and Radioactive Material Control During plant tours, the inspectors verified that contaminated materials were properly bagged, surveyed, labeled, and segregated from work areas. The inspectors verified that drums containing radioactive materials were properly labeled identifying the drum contents and associated radiation level.
The inspectors observed workers using contamination monitors to determine if various tools and equipment were potentially contaminated and met criteria for releasing the materials from the RCAs.
The inspectors reviewed the site procedure used to inventory and leak test radioactive check sources. The inspectors reviewed current source inventories and leak test results to confirm that sources were properly controlled, met the leak test acceptance criteria, and were accounted.
External Dosimetry The inspectors verified that detailed procedures associated with dosimeter use were implemented, including routine optically stimulated luminescent dosimeter issuance, multi-badging, and extremity dosimeter use. The inspectors verified that procedural controls were in place for external effective dose equivalent determinations that would be used for high dose gradient tasks and verified through observations that dosimeters were worn on the workers body location receiving the highest dose rate. The inspectors reviewed CRs related to the proper use of dosimetry to determine if the cause was properly determined and that the corrective actions were effective to preclude recurrence.
Radiation Worker and Radiation Protection Technician Performance During tours of RCAs, the inspectors questioned radiation workers and RP technicians regarding the radiological conditions at the work site and the radiological controls that applied to their task. Additionally, radiological-related CRs were reviewed to evaluate if the incidents were caused by repetitive radiation worker or technician errors and to determine if an observable pattern traceable to a similar cause was evident.
The inspectors observed pre-job RWP briefings to determine if workers were properly informed including identification of the radiological conditions associated with their tasks, electronic dosimetry dose and dose rate set points, and contamination controls and dose mitigation measures.
Problem Identification and Resolution The inspectors evaluated the CAP for assuring that radiological hazard assessments and related controls were effective and properly implemented by reviewing relevant CRs, personnel contamination event reports, and electronic dosimetry alarm reports. The inspectors evaluated whether the problems were identified in a timely manner, extent-of-condition and cause evaluations were performed, when appropriate, and corrective actions were effective to preclude repetitive problems.
b. Findings
No findings were identified.
2RS2 Occupational ALARA Planning and Controls
a. Inspection Scope
During the period March 11 to 14, 2013, the inspectors performed the following activities to verify that Constellation staff was properly implementing operational, engineering, and administrative controls to maintain personnel exposure ALARA for activities performed during routine plant operations. Implementation of these controls was reviewed against the criteria contained in 10 CFR 20 and Ginna procedures.
Radiological Work Planning The inspectors reviewed pertinent information regarding site cumulative exposure history, the exposure challenges for the fall 2012 refueling outage, current exposure trends, and the 5-year ALARA exposure reduction plan.
In reviewing Ginnas ALARA program, the inspectors evaluated the departmental interfaces between RP, operations, maintenance crafts, and engineering to identify missing ALARA program elements and interface problems. The evaluation was accomplished by interviewing site staff, reviewing station ALARA committee meeting minutes, and attending an ALARA committee meeting. Additionally, the inspectors attended a training session provided to the engineering department by the RP department regarding industry unplanned exposure experiences.
Verification of Dose Estimates The inspectors reviewed the assumptions and basis for the 2012 outage exposure plan.
The inspectors evaluated the implementation of procedures associated with monitoring and re-evaluating dose estimates when the forecasted cumulative exposure for tasks was approached during the outage.
The inspectors reviewed the ALARA post-job reviews for all 2012 outage projects whose actual exposure exceeded 5 roentgen equivalent man (rem). Included in this review were scaffolding installation and removal (RWP 12-5612) and refueling activities (RWPs 12-5618/12-9618).
The inspectors evaluated whether the actual exposure was greater than 50 percent of the estimated exposure and whether the station ALARA committee promptly evaluated the effectiveness of exposure controls as the estimated dose was approached.
The inspectors evaluated the basis for dose revisions for various outage project dose estimates that resulted from exposure challenges; e.g., expanded project scope and emergent work.
The inspectors reviewed the exposures for the 10 workers who received the highest doses for 2012 to confirm that no individual exceeded the regulatory annual limit or the performance indicator criteria.
Job Site Inspections The inspectors reviewed the dose estimates provided in an ALARA challenge board and RWPs for the installation of the A and C charging pump motor variable frequency drives, a job-in-progress.
During the inspection period, the inspectors observed workers perform tasks supporting replacement of the charging pump motor drives, grinding of the turbine building floor, and cleaning of the CCW HX. Workers were questioned regarding their knowledge of job site radiological conditions and ALARA measures applied to their tasks.
Source Term Reduction and Control The inspectors reviewed the status and historical trends for the reactor coolant system source term. Through review of survey maps and interviews with the ALARA engineer, the inspectors evaluated recent source term measurements and control strategies.
Specific strategies employed during the fall 2012 outage included use of macro-porous clean-up resin, enhanced chemistry controls, system flushes, maximizing SG water levels, and temporary shielding.
For ongoing operations, the inspectors assessed the effectiveness of temporary shielding and tank/pipe flushing for reducing auxiliary building area dose rates that were affected by the residual irradiated metallic debris material from the removal of reactor baffle plate bolts. The inspectors evaluated the effectiveness of the residual irradiated metallic debris material clean-up project by reviewing survey maps and postings.
Problem Identification and Resolution The inspectors reviewed elements of the CAP related to implementing the ALARA program to determine if problems were being entered into the program for timely resolution. CRs related to programmatic dose challenges, personnel contaminations, dose and dose rate alarms, and the effectiveness in predicting and controlling worker exposure were reviewed.
b. Findings
No findings were identified.
2RS4 Occupational Dose Assessment
a. Inspection Scope
During the period March 11 to 14, 2013, the inspectors reviewed occupational doses to ensure they were appropriately monitored and assessed. The inspectors used the requirements in 10 CFR Part 20, the guidance in Regulatory Guide (RG) 8.13, Instructions Concerning Prenatal Radiation Exposures, RG 8.36, Radiation Dose to Embryo Fetus, RG 8.40, Methods for Measuring Effective Dose Equivalent from External Exposure, TSs, and Ginnas procedures required by TSs as criteria for determining compliance.
Audits and Self Assessments The inspectors reviewed the results of Constellations RP program audits and self assessments related to internal and external dosimetry. A review was conducted of procedures associated with dosimetry operations including issuance and use of external dosimetry, assessment of internal dose, and evaluation of dose assessment for radiological incidents.
The inspectors evaluated the procedural requirements for determining when external dosimetry and internal dose assessments were required.
External Dosimetry The inspectors evaluated whether Constellations dosimetry vendor was accredited with the National Voluntary Laboratory Accredited Program. The inspectors evaluated the onsite storage of the optically stimulated luminescent dosimeters before issuance, during use, and before processing and reading. The inspectors also reviewed the guidance provided to radiation workers with respect to care and storage of dosimeters.
The inspectors assessed the methods used to determine the background radiation contribution to the dosimeter and how the background correction factor is applied to determine the dose of legal record.
Internal Dose Assessment The inspectors reviewed implementation of the internal dose assessment program.
Included in this review were calculations of derived air concentrations from airborne monitoring and bioassay techniques. These methods were applied in response to an incident in which the isotopic results from a personnel lapel air sampler indicated the presence of trace contamination during the fall 2012 outage. To accurately assess dose to the worker, Constellation analyzed the lapel air sample, conducted whole body counting, and initiated in-vitro (urine and fecal) analyses. The final committed effective dose equivalent was determined to be less than 1 mrem. The inspectors evaluated the techniques used to establish the uptake to the individual and the resulting dose.
Declared Pregnant Workers The inspectors assessed the process used by Constellation to inform workers of the risks of radiation exposure to the embryo/fetus, the regulatory aspects of declaring a pregnancy, and the specific process to be used for monitoring and controlling exposure to a declared pregnant worker. The inspectors reviewed Constellations documentation and monitoring results for one declared pregnant worker who was employed during the inspection period.
b. Findings
No findings were identified.
