Facilities Radiation Protection Section Facilities Radiological Safety and Safeguards Branch Division of Radiation Safety and Safepards Areas Inweted: Special, announced inspection by a region-based inspector to determine the status of remediation activities at the site.
Results: The remediation activities were proceeding on schedule and the licensee expected to have the remediation activities completed by November 16,1992 and a survey report issued to the NRC by December 1,1992. Within the scope of the inspection, no safety concerns or violetion of regulatory requirements were identified.

Iklalls 1.0 Individuals Contacted R. L. Churchill, Program Manager M. J. Elliott, Manager of Environmental Engineering M. Henault, Remediation Contractor F. J. Veale, Manager of Safety, Industrial. Hygiene and Environmental Engineerin, 2.0 Site Tour During this inspection, the inspector observed remediation activities in process, it was noted that the entire area between the Building 11 and Building 12 parking lots was affected by these activities. The affected area covered about 2.5 acres. Of this, about 0.5 acres was excavated to about 10 feet deep as shown in Attachment 1.
Piles of overburden soil covered about one acre.
The inspector noted that the licensee had established a contamination control change line; that individuals working in the affected area were wearing breathing zone air samplers; 4
and that at least four environmental air samples had been installed in the area. One environmental air sampler was located in the Northeast corner of the site, another was located on the north edge of the site, and, a third sampler was located on the south edge of the site. The last sampler was relocated, as necessary adjacent to work areas.
3.0 Review of Air Snmpline Results 3.1 Breathine Zone Air Samnies The inspector reviewed the licensee's records of breathing zone air sampling results for the time period September 15 to October 31.1992. The results indicated that the workers were not exposed to any significant airborne radioactivity.
The maximum exposure was about 2 maximum permissible concentration - hours (mpc-hrs) expcsure for uranium.
The maximum permissible concentration for insoluble uranium specified in 10 CFR 20, Appendix B, Table 1, Column 1 is 1.0E-10 microcuries per cubic centimeter.
No inadequacies were identified.
3.2 Environmental Air Samnies The inspector reviewed the licensee's records of environmental air sampling results for the time period September 15 to October 31,1992. Typical results indicated the presence of about one to two percent of the maximum permissible concentration (MPC) for uranium specified in 10 CFR 20, Appendix B, Table 2, Column 1 in air. The maximum air concentration measured was about 20% of the applicable MPC. The applicable MPC for insoluble uranium in air is 4.0E-12 microcuries per cubic centimeter.

4.0 Future Actions 4.1 Licensee The licensee expected to complete site remediation activities by November 15, 1992. The final shipment of contaminated soil was expected to leave the site no later than November 16, 1992. Following the completion of remediation activities, the licensee expected to initiate the final " bottom of the hole" surveys. These surveys will include soil sampling and analyses. That survey report was expected to be completed and sent to the NRC Region 1 office for review on or before December 1,1992.
Upon completion of verification surveys by the NRC, the licensee will fill the excavated areas on site and will conduct a final survey and soil sample analysis of the entire affected area. Upon completion of that survey, a final survey report will be prepared and submitted to the NRC. That report will also contain a 3
residual radindon dose evaluation and a request for license termination.
4.2 NRC Upon receipt of the " bottom of the hole" survey report, the NRC will evaluate the report and arrange for a verification survey to be conducted by the NRC contractor, the Oak Ridge Institute for Science and Education. That survey is expected to take place during the week of December 14, 1992. NRC also expects to conduct a final verification survey of the affected area of the site during the spring of 1993.,
i 5.0 Licensee Discussions In lieu of an exit interview, the inspector held continuing discussions with the individuals identified in Paragraph 1.0 throughout the inspection on November 3,1992. These discussions provided the licensee representatives with the results of the inspection.
