SUBJECT: BIG ROCK POINT INSPECTION REPORT 050-00155/06-001 (DNMS)
Dear Mr. Haas:
On September 14, 2006, the NRC completed inspection activities at the Big Rock PointRestoration Project. The purpose of the inspection was to determine whether decommissioning activities were conducted safely and in accordance with NRC requirements. Specifically, duringon-site inspections on May 8 and 9, June 2, June 13 through 15 and July 5, 2006, the inspector evaluated decommissioning and demolition activities, management oversight of decommissioning activities, radioactive waste management, radiological safety, self-
assessments, and radiological surveys. In addition, NRC in-process/confirmatory surveys wereconducted by an NRC inspector on June 2 and July 5, 2006, and on June 13 through 15, 2006by personnel from the Oak Ridge Institute of Science and Education (ORISE). Soil samples were also collected for radiological analysis by the NRC on June 2 and July 5, 2006, and byORISE during each of the confirmatory survey inspections. At the conclusion of on-site inspections on May 9, June 2, June 15 and July 5, 2006, the inspector discussed the inspection findings with you and/or members of your staff. On September 13, 2006, the inspector completed an in-office review of laboratory analysis results for soil samples collected during the May through July inspections. The inspector conducted a telephone exit interview with you on September 14, 2006, to discuss the results of the in-office review of the laboratory results.This inspection consisted of an examination of decommissioning activities at the Big Rock PointRestoration Project as they relate to safety and compliance with the Commission's rules and regulations. Areas examined during the inspection are identified in the enclosed report.

Cameron, ChiefDecommissioning Branch, Division of Nuclear Materials Safety 2EnclosureEXECUTIVE SUMMARYConsumers Energy CompanyBig Rock Point Restoration ProjectNRC Inspection Report 050-00155/06-001(DNMS)These routine decommissioning inspections involved a review of the Consumers EnergyCompany's and its contractors' performance related to decommissioning activities, management oversight of decommissioning activities, radioactive waste management, final status surveys, and radiological safety. During this inspection period, major activities included building demolition, shipment of radioactive waste for disposal, and final status surveys of excavated areas.Decommissioning Performance and Status Review*The inspector determined that the licensee's meetings and pre-job briefs were properlyfocused and work was performed in a safe manner. The licensee and its contracted workforce conducted work safely and in accordance with good radiological work practices, surveys were performed by qualified personnel, and radiological material was appropriately controlled. (Section 1.0)Solid Radioactive Waste Management*The inspector determined that the licensee adequately controlled radiologicallycontaminated demolition debris. (Section 2.0)Inspection of Final Surveys*A review of licensee survey records and independent in-process confirmatory surveysfor residual radioactive contamination throughout the Big Rock Point site confirmed that the licensee is performing remediation and final status surveys consistent with the License Termination Plan (LTP). None of 52 soil samples collected identified radiological contamination in excess of the derived concentration guideline levels (DCGLs) for cesium-137 and cobalt-60 as described in the licensee's LTP. Licensee records also demonstrated that tritium levels in the ground water have remained below the EPA drinking water standard since 2000. (Section 3.0)Self-Assessment, Auditing and Corrective Action*The inspector reviewed three instances in which the licensee responded to incidentsinvolving the transportation of contaminated waste from Big Rock Point. In all three instances the licensee's response was immediate, appropriate and addressed all concerns. (Section 4.0)

3EnclosureReport Details 11.0Decommissioning Performance and Status Review (71801)1.1Inspection ScopeThe inspectors attended and observed the conduct of licensee meetings regardingdecommissioning activities, including numerous pre-job briefs regarding final status surveys of excavated areas. The inspectors performed plant tours to observe licensee soil remediation, demolition and survey activities to verify that the licensee and its contracted workforce conducted work safely, were qualified to perform their work, and that radioactively contaminated material was controlled. 1.2Observations and FindingsThe licensee's meetings were attended by all personnel participating in the work to beperformed, adequately covered issues and concerns, provided safety briefings for each activity, and ensured that expectations were communicated to the work force. Although safety concerns regarding radiological materials at the site had significantly decreased, licensee management continued to stress safe nuclear work practices. During site tours licensee staff were observed adhering to radiological and safetyboundaries, field activities were performed safely and had adequate supervisory oversight, and radioactively contaminated material was appropriately controlled. The licensee implemented required work practices and key activities were effectively coordinated with all on-site work groups. Surveys were performed by qualified radiation protection technicians and survey instrumentation was calibrated and source-checked in accordance with procedures. 1.3ConclusionThe inspector determined that the licensee's meetings and pre-job briefs were properlyfocused and work was performed in a safe manner. The licensee and its contracted workforce conducted work safely and in accordance with good radiological work practices, surveys were performed by qualified personnel, and radiological material was appropriately controlled. 2.0Solid Radioactive Waste Management (86750)
2.1Inspection ScopeThe inspector reviewed the licensee's control and handling of contaminated demolitiondebris.
4Enclosure2.2Observations and FindingsThe inspector observed the loading of intermodal transport containers onto six railcarsfor shipment to Utah for disposal. Sufficient personnel were present and attentive to the work to ensure the intermodals were safely loaded. A radiation protection technician verified the intermodals were loaded in the correct sequence, and conducted radiation surveys of the shipment.
2.3ConclusionThe inspector determined that the licensee adequately controlled radiologicallycontaminated demolition debris. 3.0Inspection of Final Surveys (83801)
3.1Inspection ScopeLicensee records of previously performed final status surveys were reviewed, as was alicensee document addressing onsite tritium monitoring wells. Independent radiological confirmatory surveys and soil sampling was conducted throughout the site, including the reactor building and turbine building excavation areas. Analyses were performed on radiologically contaminated soil samples provided by the licensee to assess the adequacy of the licensee's radioanalytical capability.3.2Observations and FindingsTwenty-nine licensee final status survey records were reviewed, which included nine soilexcavation areas and 20 surveys of soil for backfilling into the excavation areas. All 29of the final status surveys demonstrated that the soil excavated areas and the soils forbackfilling were less than the derived concentration guideline levels (DCGLs) for soil of11.93 picocuries per gram (pCi/g) for cesium-137 (Cs-137) and 3.21 pCi/g for cobalt-60 (Co-60) as described in the licensee's License Termination Plan (LTP). The inspectors also reviewed the licensee's Engineering Analysis Work Sheet, EA-BRP-RAE-0604, Tritium in Non-Committed Monitoring Wells. Based on the sample data provided, the inspectors concurred with the licensee's conclusion that the 5 wells discussed in the analysis were consistently at least 5 percent below the Environmental Protection Agency(EPA) drinking water standard for tritium since January 2002 and could be closed. The remaining wells required by the LTP will remain operable.The Oak Ridge Institute for Science and Education (ORISE) conducted independentin-process confirmatory surveys for the NRC of selected survey units (SUs) thr oughoutthe site. The surveys were performed over 20 to 80 percent of the accessible ground surfaces within the SUs using sodium iodide (NaI) scintillation detectors. Some of the areas scanned included the reactor building and turbine building excavation areas, the 5Enclosurebeach and parking areas, and the former transmission line corridor. The soil surfacescanning only identified 2 to 3 small areas of radiological contamination in areas where the licensee had not conducted final status surveys, and these areas of contaminationwere promptly remediated by the licensee. ORISE also collected 46 surface soil samples from judgmentally selected locationsthroughout the site. In addition, during inspections on June 2 and July 5, 2006, an NRC Region III inspector conducted independent in-process confirmatory surveys andcollected six soil samples in portions of the reactor building, turbine building and service building excavation areas. The soil samples collected by the NRC were analyzed byORISE for Co-60 and Cs-137, and the soil samples collected by ORISE were analyzed for tritium (hydrogen-3), Co-60, Cs-137, europium-152, europium-154, europium-155 and manganese-54. The analyses of the soil samples collected during the inspections identified no contamination in excess of the licensee's DCGLs for Cs-137 and Co-60. The licensee also provided ORISE with three previously collected surface soil samplesso that ORISE could verify the adequacy of the licensee's radiological counting capability. There was acceptable agreement between the licensee's and ORISE'sanalytical results for these samples.A report was issued by ORISE dated September 25, 2006, detailing the scope andresults of their survey and sampling activities at Big Rock Point (see ADAMS ML062728126). A separate report was issued by ORISE on August 4, 2006, that provided the results of the radiological analyses of the six soil samples collected by the NRC (see ADAMS ML062200299).3.3ConclusionA review of licensee survey records and independent in-process confirmatory surveysfor residual radioactive contamination throughout the Big Rock Point site confirmed that the licensee is performing remediation and final status surveys consistent with the LTP. None of 52 soil samples collected identified radiological contamination in excess of the DCGLs for Cs-137 and Co-60 as described in the licensee's LTP. Licensee records also demonstrated that tritium levels in the ground water have remained below the EPA drinking water standard since 2000.4 .0Self-Assessment, Auditing and Corrective Action (40801)
4.1Inspection ScopeThe inspector reviewed the licensee's response to two incident's involving rail shipmentsof radioactive waste to Utah and one incident involving the transport of radioactive waste to Tennessee by truck.
6Enclosure4.2Observations and FindingsOn June 14 and 15, 2006, the licensee was loading 42 intermodals of contaminateddemolition debris onto six rail cars in Petoskey, Michigan, prior to shipping them to Utah for disposal. While the crane was loading the 32 nd intermodal, the brakes released ontwo of the rail cars, which included the car on which the intermodal was being loaded.
Due to the grade where the rail cars were parked, the two cars started to slowly rolling. Because the crane was still attached to the intermodal, which had already been set andpinned in place, the crane operator turned the crane and let his line play out until he wasappropriately positioned to stop the rail cars. The rail cars rolled about 80 feet before being stopped. The licensee's immediate actions after pulling the rail cars back intoplace was to set all the hand brakes and block the wheels. As an additional precaution, another crane that was available was attached to the cars to also prevent movement until the remaining intermodals were loaded and the rail cars were shipped. Personnel from the railroad indicated that the air brakes, which had been set, had slowly bled off to the point they could no longer hold the rail cars in place as additional weight was added.On June 16, 2006, as the 42 intermodals were being shipped, 17 rail cars derailed nearFarwell, Michigan, from the same train that was hauling the intermodals from Big Rock Point. Although none of the rail cars carrying the 42 intermodals derailed, the news media implied that they had, and stated that they were carrying water that was used tocool the reactor at Big Rock Point. The licensee responded by immediately sending someone to the scene to verify the condition of the intermodals, including verifying that they were not involved in the derailment. They were also aggressive in contacting the news media and NRC to ensure the correct information was available regarding thewaste shipment.On March 11, 2006, a tractor-trailer hauling contaminated demolition debris from BigRock Point to Tennessee crashed on Interstate 75 near West Chester, Ohio. The material was being shipped as a DOT exempt quantity so the vehicle was not placarded.
The shipping papers indicated a maximum concentration of 3 pCi/g of Cs-137. Although none of the load spilled during the accident, the tractor-trailer disconnected from thewrecker as the wrecker attempted to pull the tractor-trailer back onto the road, fallingback and causing part of the debris to be spilled. The licensee responded immediatelyby dispatching personnel to the scene. The spilled waste was cleaned up and placedinto twelve 55-gallon drums. The rest of the waste was transferred to a new truck, and that truck and another truck carrying the 55-gallon drums were both out of Ohio by thatnight. Followup surveys conducted by personnel from the State of Ohio indicated there was no residual contamination at the accident site in excess of twice background.4.3ConclusionThe inspector reviewed three instances in which the licensee responded to incidentsinvolving the transportation of contaminated waste from Big Rock Point. In all three instances the licensee's response was immediate, appropriate and addressed all concerns.
7Enclosure5.0Exit Meeting SummaryThe inspector presented preliminary inspection findings to members of the licenseemanagement team at the conclusion of onsite inspection activities on May 9, June 2, June 15 and July 5, 2006. A telephone exit interview was conducted with the Site General Manager on September 14, 2006, to discuss the results of the in-office review of the laboratory soil sample analysis results. The licensee did not identify any documents or processes reviewed by the inspector as proprietary.ATTACHMENT: SUPPLEMENTAL INFORMATION Attachment 8SUPPLEMENTAL INFORMATIONPARTIAL LIST OF PERSONS CONTACTEDConsumers Energy Company* Kurt Haas, Site General Manager* Ken Pallagi, Radiation Protection & Environmental Services Manager
