2.03 Inplant General it amplino <br />General air sampling to determine airborne uranium and radium-226 <br />concentrations in the licensed facilities was conducted in <br />accordance with License Condition 13.4.7.1, Radiological Health and <br />Safety Procedure 2-7, and License Amendment 1s4. <br />Routine sampling under RHbS Procedure 2-7 is conducted on a monthly <br />basis at the drum filter in the ore sorter and on a quarterly basis <br />at the two locations at the water treatment plant. A fourth sample <br />location, designated NDF, has been added to monitor airborne <br />concentrations in the immediate vicinity of the new drum. filter <br />system located at the wastewater treatment facility. The NDF <br />location will be monitored routinely during drum filter operation. <br />The Procedure 2-7 revision will be submitted with the rest of tha <br />RH6S Procedure revisions. <br />Airborne concentrations at the four sampling locations for the <br />reporting period are presented on the following pagan. The NDF <br />location was sampled once in the first quarter of 1993 during a <br />trial run period far the new drum filter. The new drum filter has <br />not operated since the first quarter of 1993 pending a rebuild of <br />the deep-bed pressure filters in the wastewater treatment plant. <br />Sample results at all locations are less than 1.0$ MPG. The only <br />identifiable trends can be attributed to seasonal fluctuations <br />linked to increased building tightness during cold weather. <br />
