Report Details1 1.0 Decommissioning Support Activities 1.1 Status of Decommissioning (71801, 83750)

a. Inspection Scope The inspectors evaluated decommissioning activities to ensure they were conducted in a manner that protected the health and safety of workers and the general public.

b. Observations and Findings The inspectors observed numerous decommissioning activities during several comprehensive plant tours. The activities observed by inspectors included: scabbling of building surfaces, decontamination and surveys of equipment and building surfaces, radiation protection work practices, movement of heavy loads, demolition activities, and licensee oversight of decommissioning work. During the plant tours, the inspectors discussed work hazards with health physics technicians and workers to verify they understood the radiological issues pertinent to their assigned work.

The licensees staff and contractors were cognizant of the radiological conditions in their work area and aware of what actions could cause the radiological conditions to change.

In addition, the licensees staff and contractors communicated effectively, demonstrated appropriate concern for industrial safety, conducted work in accordance with applicable procedural requirements, and employed adequate work practices to ensure safety. The inspectors noted that the material condition of facilities and equipment was acceptable and housekeeping within the controlled area was adequate.

The inspectors observed that the licensees staff and contractors wore appropriate anti-contamination clothing and dosimetry, followed the proper technique when removing their anti-contamination clothing, and performed exit monitoring adequately.

c. Conclusion The inspectors determined that licensee and contractor personnel were cognizant of the radiological conditions in their assigned work area. The inspectors concluded that the licensee and its contractors conducted decommissioning activities in a manner that protected the health and safety of workers and the general public.

1.2 Self-Assessment, Auditing and Corrective Actions (40801)

a. Inspection Scope The inspectors evaluated the management teams disposition of select condition reports.

A list of acronyms used in the report is included at the end of the report.

b. Observations and Findings The inspectors observed site management assess numerous condition reports (CRs),

including: C-BRP-04-069, C-BRP-04-0073, C-BRP-04-080, C-BRP-04-091, and C-BRP-04-092. The management team assessed each CR in accordance with applicable procedural requirements to determine if all the information was available regarding the issue, to characterize the issue, to determine if the root cause was appropriate, and to identify the appropriate corrective or follow-up action necessary to resolve the issue. Once the management team understood the significance of each issue they were able to develop appropriate corrective actions to address the cause(s)

and prevent recurrence.

The issues reviewed by the inspectors were either safety and health or radiological concerns identified by the workers or managers. Based upon a review of the information associated with the CRs, the inspectors determined that the corrective actions proposed by the management team were responsive to the identified concerns.

c. Conclusions The licensees management team adequately characterized CRs and developed appropriate corrective actions to prevent recurrence. The inspectors concluded that licensee management adequately implemented the CR program.

2.0 Radiological Safety 2.1 Inspection of Final Surveys (83801)

a. Inspection Scope The inspectors reviewed the licensees documentation and interviewed the staff regarding the conduct of and the results associated with the decommissioning survey activities.

b. Observations and Findings The inspectors reviewed the following Information, Survey, and Verification work packages:

1. Work Package 2003-0084, Turbine Building, B-3, Room 126/127; 2. Work Package 2003-0085, Turbine Building, Room 105/111; 3. Work Package 2003-0085A, Turbine Building, Room 105/111; 4. Work Package 2003-0086, Turbine Building Room 112 Turbine Lube Oil Tanks; 5. Work Package 2003-0091, Turbine Building Room 113 Stairwell No. 8;"

The inspectors noted that each completed work package contained pre-demolition radiological survey results, verification survey results, historical basis for survey area classification, instrumentation calibration information, survey grid layouts, and photographs of the survey areas. The inspectors also noted the work packages were complete and contained sufficient detail to support the conclusions contained within the package.

The inspectors determined that the survey package included sufficient information to document that surveys were conducted in accordance with the licensees decommissioning procedures. The inspectors observed that the verification survey teams adequately conducted their surveys and were independent of the survey teams conducting screening and final surveys.

c. Conclusions The inspectors concluded that the licensee implemented the radiological survey program in accordance with approved decommissioning procedures.

2.2 Solid Radioactive Waste Management and Transportation of Radioactive Materials (86750)

a. Inspection Scope The inspectors evaluated the licensees method for processing waste and shipment of low-level radioactive waste.

b. Observations and Findings The inspectors reviewed a licensee document dated August 20, 2003, entitled Release of Materials to the Waters Landfill Through the Bulk Material Counting System. This document addressed the release of legacy asphalt and concrete material that had been stored along the old power line right-of-way. The inspectors determined that the August 20, 2003, document adequately addressed the handling of the legacy asphalt and concrete material.

The inspectors observed the preparation of a low-level radioactive waste shipment and determined that the transport vehicle was properly placarded and the individual containers were appropriately prepared and labeled. The inspectors conducted independent and confirmatory radiation surveys of the loaded vehicle and obtained survey results consistent with the licensees pre-shipment survey results. The inspectors reviewed the shipping papers associated with the shipment and determined that the papers contained the required information and were readily available and stored as required.

c. Conclusions The inspectors concluded that the licensee met regulatory requirements for the processing and shipping of low-level radioactive waste for disposal.

2.3 Radioactive Waste Treatment, and Effluent and Environmental Monitoring (84750)

a. Inspection Scope The inspectors evaluated the licensees collection of soil samples and obtained split samples for independent analysis to evaluate the licensees environmental monitoring program.

b. Observations and Findings The inspectors observed the licensee collect soil samples in conjunction with conducting final status surveys of soil excavated as a result of construction activities. The licensees environmental management staff ensured the area had been properly prepared before sampling. The 18 sites selected for sampling were an accordance with approved decommissioning procedures. The inspectors noted that the licensees procedures and techniques for the collection of environmental soil samples were adequate.

The inspectors conducted independent and confirmatory radiological surface scans. In addition, the inspectors randomly selected 3 of the 18 soil samples collected by the licensees staff to split for independent NRC analysis at the Oak Ridge Institute of Science and Education (ORISE).

The results of the analyses are listed in Table 2.3. The inspectors compared the analytical results obtained by the NRCs contractor, licensee, and ORISE for cobalt-60 (Co-60) and cesium-137 (Cs-137) and noted that all three samples contained less than the minimum detectable concentration (MDC) of Co-60 and slightly greater than the MDC of Cs-137. However, the Co-137 concentrations were consistent with background levels.
