Michael C Wynn <[email protected]> Sent by: [email protected] 07/07/2011 10:40 AM Please respond to [email protected] To "[email protected]" <[email protected]> cc Subject Powernet: Bulk Volumetric Material Release from Protected or Controlled Areas Millstone Power Station would like to know concerning release of bulk volumetric materials from the Protected or Controlled Areas the following questions: 1. What are the radiological controls at your station for activities in areas outside the RCA, but within the Protected Area (also known as Restricted Area for radiation protection purposes), that involve renovation, repair, excavation, drilling, digging or cutting of material, components or soil that contain or may contain radioactive material? It depends on the level of radioactive material. Generally there is no dose or contamination issue, so bulk materials are radiologically evaluated for unconditional release. What are the radiological controls for these activities in the Controlled Area (as defined in 10 CFR 20)? Usually only segregating for subsequent disposal or disposition. 2. If applicable, is there guidance on determining: ?contain or may contain radioactive material?? All materials inside the Protected Area would be analyzed for radiological content. 3. Is any allowance made for residual Cs-137 in soil from weapons fallout that is not considered licensed radioactive material from plant operations? Cook Plant has analyzed for environmental fallout levels of Cs-137 and is very close to the environmental effluent LLD. If identified at or below this level, it is not considered to be from plant operations. 4. How is RP notified of these types of activities outside the RCA? Stated on the Work Order. 5. If an RWP is required: An RWP is generally not requied since it is not a dose or contamination issue. a. What general controls are specified? b. Are all supplemental personnel (for example roofers, laborers) required to have full radiation worker qualification, or a lower level such as escorted radiation worker? No. c. Do the workers log-on the exposure control system with an electronic dosimeter for the RWP and wear the dosimeter during work activities? No. Thank you all in advance for you help. Michael C.
