.ASurvey Area RequirementsFinal Status Survey, Release Record 09C 11North East Protected AreaSurvey DescriptionFinal Status Survey 09C, 1 encompasses 1989 m2 at or below the grade elevation presentduring plant power operations in the north east section of the Protected Area. No materials ofplant origin remain in the survey area.HistoryDuring power operations the Protected Area supported the components and systems necessaryfor electrical generation. The location of Survey Unit 9 is adjacent to the transport route used tomove spent resin and filter media for radiological survey and offsite removal. Structures andenclosures formerly located in this area were once used for the storage of contaminatedmaterials. A detailed review of the history and radiological characterization of survey Unit 9 isprovided in Appendix 2B and 2E of the LTP (License Termination Plan).Current Radiological StatusScoping measurements and supporting surveys performed in the Protected Area followingremoval of subsurface components and demolition debris do not indicate the presence ofelevated levels of residual radioactivity in this survey area. Based on operational history andformer locations of radioactive systems and material transport pathways, the radiological statusof this survey unit is Class 1.Post-Construction ExpectationsFinal Status Survey 09C1 1 will be performed in the following activity sequence:1. Walkdown: Environmental Services Survey Group (ESSG) personnel will perform awalkdown assessment to ensure survey area preparations are complete and confirmthat the following post-construction expectations have been satisfied as applicable:" Groundwater and Surface water control is adequate" All construction debris has been removed from the survey area* The survey location status meets all applicable safety requirements2. Survey Area Isolation and Control: Control measures will be established to ensure thatany potential ongoing decommissioning activities in adjacent locations do not impact thecurrent survey area status. Isolation and control measures include postings, barriers,access points, and the evaluation of ongoing work activities in adjacent areas.Survey Area RequirementsFSS 09Ci 1Page 1 of 2

DATA QUALITY OBJECTIVESFinal Status Survey, Release Record 09C1 1North East Protected AreaSTATE THE PROBLEMThe Problem:To demonstrate that the level of residual radioactivity in Class 1 Survey Unit 09 does notexceed the release criteria of 25 mrem/year Total Effective Dose Equivalent (TEDE) asspecified in the License Termination Plan (LTP).Stakeholders:The primary stakeholders interested in the answer to this problem are ConsumersEnergy Co., and the general public as represented by the Michigan Department ofEnvironmental Quality (MDEQ), and the US Nuclear Regulatory Commission (USNRC).The Planning Team:The planning team consists of members of the BRP Environmental Services SurveyGroup (ESSG). The primary decision maker will be the Final Status Survey Supervisor.The Final Status Survey Supervisor will obtain input from the site Construction Groupand Scheduling Group for issues relating to schedule and costs.Schedule:Approximately five (5) working days are projected to implement the survey and to collectand analyze field data.Resources:The primary resources needed to determine the answer to the problem are two (2)technicians to perform fieldwork, one (1) technician to prepare the samples and conductlaboratory analyses, and two (2) survey team members to prepare and review thedesign, generate maps, coordinate field activities and evaluate data.2.IDENTIFY THE DECISIONSeveral decisions need to be defined to address the stated problem.PrincipalStudy Question (1):Does the mean concentration of residual radioactivity in the survey unit exceed therelease criteria stated above?Decision (1):Determine whether the mean concentration of residual radioactivity in the surveyexceeds the release criteria stated in the problem.Actions (1):Alternative actions include failure of the survey unit, remediation, or no action required.Data Quality ObjectivesFSS 09C I1Page 1 of 5
PrincipalStudy Question (2):Do any areas of elevated activity in the survey unit exceed the release criteria?The Decision (2):Determine if any areas of elevated activity in the survey unit exceed the release criteria.Actions (2):Alternative actions include confirmation and investigation, performing the elevatedmeasurement comparison (EMC), remediation, or no action required.PrincipalStudy Question (3):Is the potential dose from residual radioactivity in the survey unit ALARA as stated?The Decision (3):Determine if the potential dose from residual radioactivity in the survey unit is ALARA.ALARA requirements for soil remediation are defined in Chapter 4 of the LTP.Actions (3):Alternative actions include remediation or no action required.3.IDENTIFY INPUTS TO THE DECISIONInformation Needed:Characterization measurements are required to define the radionuclides present anddetermine the extent and variability of residual radioactivity in the survey area for designand implementation of the survey. Survey area classification, ALARA analysis, potentialradionuclides of interest, and site-specific DCGL values are also required inputs to thedecision process. The primary information required for evaluation is the analyticalresults of survey measurements.Source of the Information:The soil sample data to be used for survey development are the radionuclide-specificmeasurements of representative soil samples collected for radiological characterizationand excavated soil surveys conducted to determine suitability for transport of excavatedsoil to the SVA. The soil samples obtained were judgmentally selected as a result ofmultiple surveys conducted during the excavation and transport process. The ALARAanalysis for potential soil remediation is provided in LTP, Section 4.4. Site-specificDCGL values and BRP radionuclides of interest are defined in LTP Chapter 5, Table 5-1and Procedure RM-76, FinalStatus Survey Design.The survey will be conducted in accordance with applicable regulatory guidance asestablished in LTP Chapter 5 for Class 1 areas. Soil samples will be utilized forradionuclide-specific measurements in this evaluation.4.BOUNDARIES OF THE STUDYBoundaries of the Survey:The target population for this survey is the total thickness of prepared soil in the surveyarea of 1989 M 2 .Data Quality ObjectivesFSS 09C11Page 2 of 5
Temporal Boundaries:Scanning and sampling in this survey unit will only be performed during daylight hoursunder dry weather conditions. Surface soils must be free of significant snow cover andstanding water prior to surface scanning. Soils must be in a non-frozen state orfragmented for collection to satisfy BRP procedural sampling requirements. Theanticipated start date for the survey is September 13, 2006.Constraints:Cold weather or rainy conditions may effect the operation of electronic equipment.Adverse weather conditions that include accumulations of rain or snow may limit areaaccess and delay survey efforts.5.DEVELOP A DECISION RULEThe following decision rules have been developed to define a logical process forchoosing among alternative actions for the principal study questions associated with thissurvey area.Decision Rule (1):If all reported concentrations for residual radioactivity are less than the site-specificDCGL's and the unity rule has been satisfied for each sample, then the survey unitmeets release criteria. No further action is required.Decision Rule (2):If the mean value of activity in the survey unit is greater than the DCGL, then the surveyunit fails to meet the release criteria.1 Remediate, resurvey, and evaluate the resultsrelative to the decision rule.Decision Rule (3):If the mean activity in the survey unit is less than the DCGL and any individual samplemeasurement exceeds this value, conduct the Sign Test and the elevated measurementcomparison (EMC) per LTP, Chapter 5 and Procedure RM-76, Final Status SurveyDesign. If the EMC and the Sign Test have been satisfied then the survey unit meetsthe release criteria and no further action is required. If the EMC or the Sign Test has notbeen satisfied then remediate the area(s) of elevated activity, resurvey as appropriate,and evaluate the results relative to the decision rule.Decision Rule (4):If the potential dose from residual radioactivity in the survey unit is ALARA, then nofurther action is necessary. If the potential dose from residual radioactivity in the surveyunit is not ALARA, then remediate and resurvey.6.SPECIFY TOLERABLE LIMITS ON DECISION ERRORSThe Null Hypothesis:It is assumed that residual radioactivity in the survey unit exceeds the release criterion.multiple radionuclides are present the mean activity value is determined as the average of theweighted sum. The DCGL of the weighted sum is 1.1 WhenData Quality ObjectivesFSS 09C11Page 3 of 5
Type I Error(a):The a error is the maximum probability of rejecting the null hypotheses when it is true.Thea error is defined in the LTP at a value of 0.05 (5%) and cannot be changed to aless restrictive value unless prior approval is granted by the USNRC. The a error valueof 0.05 will be used for survey planning and data assessment for this survey area.Type II Error(/3):The 83 error is the probability of accepting the null hypothesis when it is false. A valueof 0.05 (5%) will be used for survey planning and data assessment for this survey area.The Lower Bound of the Gray Region (LBGR):The LBGR is initially set at one-half the DCGLw for this survey unit. The LBGR may beadjusted during survey design to achieve an optimum relative shift between 1.0 and 3.0.Relative Shift (A/a):The relative shift will be maintained within the range of 1.0 and 3.0 by adjusting theLBGR as appropriate.7.OPTIMIZE DESIGN FOR OBTAINING DATAStatistical TestSign Test:Radionuclides of potential plant origin also present in soil as background activityresulting from fallout constitute only a small fraction of the DCGL. Therefore, the SignTest will be used where applicable in the survey evaluation to determine if the surveyarea meets the requirements for unrestricted release.Number of Samples Determined:The number of samples required for this survey will be determined based on the relativeshift as defined by the requirements of the Sign Test (LTP, Chapter 5.) and ProcedureRM-76, Final Status Survey Design. The LBGR is initially set at one-half the DCGLw andmay be adjusted as necessary for optimizing the survey design to achieve a relative shiftbetween 1.0 and 3.0. Sample point locations are to be determined using a random start,systematic square grid spacing.Judgmental Sampling:Co-60 is the most limiting radionuclide for identification by surface scanning; judgmentalsurface and subsurface core samples will be collected in any location that exceeds thescan investigation level.Scan Coverage:Scanning for this survey area will provide 100% coverage.Number of Samples for Quality Control:A minimum of 5% of the sample population will be collected for quality evaluation.These samples may include sample splits, sample recounts, or third party sampleData Quality ObjectivesFSS 09C1 1Page 4 of 5
