14. Radon and Tritium Monitoring in Nuclear Reactor Facilities Radon monitoring is performed to; alert personnel to the potential for personal contamination due to radon alert personnel to the potential for degradation in the performance of alpha CAMs alert personnel to unacceptably high levels of radon in the facility

15. Radon and Tritium Monitoring in Nuclear Reactor Facilities Tritium monitoring is performed to; alert personnel to the potential for inhalation of tritium alert personnel to the potential malfunction of plant liquid process equipment

16. Radon and Tritium Monitoring Outside Nuclear Reactor Facilities Radon monitoring is performed to establish environmental background levels of alpha and beta emitters in the ambient air.

17. Radon and Tritium Monitoring Outside Nuclear Reactor Facilities Tritium monitoring is performed to; establish a baseline level of tritium in the ambient air and water outside the facility boundary alert personnel to the potential malfunction of plant liquid process equipment

18. Special Applications for Tritium Monitors Inside Nuclear Reactor Facilities Simultaneous and separate monitoring of elemental tritium and tritium oxide can be used to identify the presence of leaks in the hydrogen recombiner in the facility. Elemental tritium will only exist for a short period of time before it either combines with an oxygen atom or it replaces a hydrogen atom on a water molecule.

19. Special Applications For Tritium Monitors For The ITER Project ITER will require a lot of tritium to start. This leads to the need for tritium monitors inside the facility, around its perimeter, and at those locations producing tritium for ITER. Tritium monitors with high working ranges will be needed for ITER in addition to conventional tritium monitors ITER is scheduled to start producing power in 2018.

20. Special Applications For Tritium Monitors For DOE DOE is continuing with refurbishing the US nuclear arsenal. The tritium in those devices must be replaced about every 15 years. The gamma radiation from the device drives the need for tritium monitors with active gamma compensation.

21. Special Applications For Tritium Monitors For DOE DOE produces and maintains a supply of elemental tritium for our weapons program. Since the elemental tritium combines with oxygen readily there is a need to simultaneously monitor for elemental tritium and tritium oxide. The presence of elemental tritium outside its containment indicates that tritium is leaking from its containment.

22. Small Transportable Nuclear Power Reactors

23. What is in the future for these power reactors ? It seem unlikely the NRC will grant operating licenses for these types of nuclear power reactors. It seems unlikely the final cost for these types of nuclear power reactors could equal that of the new commercial nuclear power reactors. Small Transportable Nuclear Power Reactors

24. Resurgence in Uranium Mining

25. Resurgence in Uranium Mining The EPA estimates there will be 10,000 to 15,000 more uranium miners in the US by 2015. The EPA is considering lowering the allowable radon exposures for uranium miners.

31. Worker Protection for Uranium Mining Radon and Airborne Uranium Monitoring Routine area radon and uranium monitoring with sophisticated instruments Radon monitoring before opening a new area to workers Personal radon and uranium monitors for workers

32. Public and Environmental Protection for Uranium Mining There is a need for a CAM for Continuously Monitoring for Airborne Alpha and Beta Activity at High Volumetric Sampling Rates.

33. Public and Environmental Protection for Uranium Mining In-Situ Mining In-Situ mining leaches the uranium ore from the underground deposit and greatly reduces the volume of above ground waste.

34. Public and Environmental Protection for Uranium Mining Open Pit Mining Reduces the risk to the workers by providing better ventilation and reduces other risks in underground mining Exposes more rock dust and uranium ore that could increase the spread of those into the environment Australias Olympic Dam mine is converting to an open pit operation

35. Public and Environmental Protection for Uranium Mining Closing and covering an open pit mine at the end of its useful life could provide the best permanent solution for protecting the public and the environment. In-Situ mining could also minimize the mines affect on the public and the environment.

44. Uranium Fuel Cycle Facilities These Facilities need Radon and Airborne Radioactivity Monitoring. Due to the presence of gamma radiation from the uranium the radon monitors need active gamma compensation.

45. Nuclear Fuel Reprocessing Better Ventilation Radiation Monitoring Airborne Radioactivity Monitoring Criticality Monitoring

46. Nuclear Fuel Reprocessing The present US political position is to NOT reprocess nuclear fuel. A small amount of plutonium and uranium are being used to produce MOX (mixed oxide fuel) but the output is small compared to the need.
