|
|
State the circumstances where items exposed to a within flux may be activated |
-Items within the primary shield complex of the RC -Items within the RC containing dissimilar metals -Components within the RC containing heavy metals -Items within the RC containing high concentrations of zinc |
|
|
State the radiological implications of items such as spot coolers that handle large volumes of air. |
Concentrators- components whose design characteristics typically contribute to a disruption in the flow of system fluid causing radioactive particles to settle out and collect |
|
|
Explain how radioactivity becomes fixed in painted surfaces |
Radioactive liquids contain small quantities of suspended insoluble metal oxides which can easily become embedded in the pores of paint when wetted by radioactive liquids |
|
|
State the article number where the identification/release requirements associated with RAM can be found |
Article 701 |
|
|
List the methods used to minimize the generation of radioactive waste from planning to completion of work. |
-Pre-plan work to minimize the amount of materials and equipment taken into CSCAs -Cover or sleeve tools and equipment to the maximum extending practicable to prevent contamination -Reuse tools and equipment already in the organizations RAM inventory as much as practicable -Segregate potentially contaminated material, non-radioactive material, and known contaminated material at the site -Survey material that can be released at the worksite Handle and package waste per TWD -Maintain good housekeeping practices |
|
|
State when and where waste should be segregated |
-At the job site -As it is generated |
|
|
List the different ways radioactive material should be sepersted |
-Compressible from non-compressible -Highly contaminated waste from low contamination level waste -Wet waste from dry waste -Hazardous from non-hazardous waste -Asbestos from non-asbestos waste |
|
|
List radioactive waste characterization types |
-Common consumable Material (CCM) -Standard Recycled Material (SRM) -Other Recycled Material (ORM) -Non-Hazardous Radioactive waste (NHRW) |
|
|
State the types of radioactive waste that can be characterized by CNPM RADCON-W-2 |
Hazardous Waste Mixed Material Mixed Waste |
|
|
List and explain techniques used to minimize the generation of mixed material/mixed waste |
Segregation- involves performing proper segregation of radioactive waste at the job site as identified by the TWD that generates the waste, the CNPM chapters, and trained attributes. Source reduction- to avoided specifying the use of hazardous materials unprocessed that have the potential of generating mixed waste and to implement reuse or recycling options Work practices- involves using trained work practice minimization techniques Up-front planning- cognizant engineering code is required to characterize radioactive waste generated by TWDs |
|
|
List the packing requirements for solid radioactive watste |
-Segregate waste -Hand-Pack bags with solid waste into containers, with high radiation levels along the centerline -Inspect containers inside and out -Take airborne, contamination, and radiation surveys Deal the containers with gasket -Estimated number of cuties inside each container -Complete records for each container |
|
|
State the purpose of RAM accountability system |
-Ensure RAN is not lost or improperly handled during transfer outside of RCAs -Account for all RAM stored outside of RCAs |
|
|
State when RAM accountability is required |
All RAM outside of RCAs is required to be under accountability, except -RAM transferred by crane from on RCA to another -RAM transfers outside of RCA -RAM accumulated at s worksite under the custody of production personnel with periodic RCT coverage -RAM moved from a worksite to a storage container, or moved between storage containers. |
|
|
List RCT responsibilities with respect to RAM accountability |
-Responsible for the accuracy of radiological survey information on the radioactive material tag (RAMT) -May initiate or close accountability -Provide oversight to ensure they temporary RAM storage areas are established properly -Provide oversight to ensure that RAM is properly packaged and identified -Provide oversight to ensure -RAM is properly moved/transferred |
|
|
Discuss the special considerations applied to RAM marking and tagging requirements when stored within CSCAs or glovebags |
Tools known to be contaminated: -Radioactive material stickers -Durable yellow or yellow and magenta tape -Yellow plastic coating -Yellow paint Tools without known contamination: -exempt from from marking/taggin |
|
|
Describe the accountability, packaging, marking, and tagging requirements for RAM when being moved within an RCA |
-RAM being moved within an RCA does not need to be placed in the RAM accountability system -RAM must be packaged in yellow wrapping material, with all openings sealed, to contain loose surface contamination -Marked as RAM -Must have a RAM tag attached -An appropriate Appendix N attached for radioactive waste |
|
|
Describe the accountability, packaging, marking and tagging requirements for RAM when being moved between CPAs |
-Needs to be placed into RAM accountability system -RAM must be packaged in yellow wrapping material, with all openings sealed, to contain loose surface contamination -Marked as RAM -RAM transfers through food preparation or messing spaces is permitted when no other route is available |
|
|
Describe the requirements used wen moving items with high radiation levels |
-Personnel associated with HRA transfer attend a job briefing -Personnel handling HRA RAM wear both TLD and PD -Cognizant engineer determines radiation and HRA boundaries -RCT accompanies HRA transfer to perform radiation surveys along boundaries -HRA guards HRA boundary -After move, RCT performs radiation survey of affected boundaries |
|
|
Discuss the procedure used to inventory RAM |
-Visually verifying each piece of RAM is in its indicated storage location as listed on the radioactive material control log -Performing a quality control check of the RAMT -Performing a quality control check of the packaging |
|
|
State the RCT immediate actions to be taken upon a loss of RAM |
-Immediately conduct a RAM search -Notify senior management |
|
|
State the commands actions to be taken upon a list of RAM |
-Immediately initiate investigation of likelihood of unmonitored personnel inside or outside of the organization receiving internal or external radiation exposure from lost RAM -Notify NAVSEA 08 if RAM is lost and likely to be accessed by unmonitored personnel -Notify local, state and federal agencies if NAVSEA directs it |
|
|
List the requirements for transporting RAM within the organization by vehicles |
-The use of bicycles and POVs is prohibited -RAM must be loaded in a way to minimize exposure to driver -Secure RAM to prevent loss or damage -Transporting RAM should be accomplished in a direct fashion, using approved traffic routes, without interruption |
