Security Requirements for Nuclear Research and Test Reactors • Security • All research and test reactors are designed and operated so that material is not easily handled or dispersed, thus protecting against potential radiological exposure or theft of material. These reactors have a limited amount of radioactive material on site and therefore pose a low risk from radiation and theft of nuclear material. The NRC inspects the reactor’s security and emergency plans, as well as its operations and design to ensure protection of public health and safety.
• Security requirements are based on a graded approach with increasing requirements for material that is more attractive for theft or diversion and for facilities that have larger inventories of radiological material. • Prior to September 11, 2001, all reactors had security plans or procedures and emergency plans as required by NRC regulations. Following the terrorist attacks on 9/11, the NRC advised licensees to consider taking additional security measures. Later NRC imposed additional security measures on research and test reactors by Confirmatory Action Letter.
• • While the specifics of these measures are not publicly available for security reasons, in general, they include: enhancements in screening of personnel; systems for controlling access to the facility; observation of activities within the facilities; alarms or other devices to detect unauthorized presence; operability of communication systems; vehicle and package searches; and heightened coordination with appropriate local, State, and Federal resources liaisons with the FAA and law enforcement authorities to report unusual overflights or potential threats.
Small Transportable Nuclear Power Reactors
Small Transportable Nuclear Power Reactors 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.
Resurgence in Uranium Mining
World Uranium Production Tons of Uranium 2007 2008 Canada 9476 9000 Kazakhstan 6637 8521 Australia 8611 8430 Namibia 2879 4366 Russia 3413 3521 Niger 3153 3032 Uzbekistan 2320 2338 USA 1654 1430 World total 41, 282 43, 853
United States Uranium Production Tons of Uranium 2007 2008 USA 1654 1430 World total 41, 282 43, 853 US Uranium Current Production is Primarily From 4 Mines. 90% of US Uranium Mining is In-Situ.

Worker, Public, and Environmental Protection for Uranium Mining • Controlled Ventilation • Radon and Airborne Uranium Monitoring • Portable and Personal Continuous Air Monitors • In-Situ Mining • Open Pit Mining
Worker Protection for Uranium Mining Controlled Ventilation • Air volume turnover rates should be > 7 per hour • Ventilation velocities should be < 0. 1 m/sec • But, underground temperatures might call for a higher ventilation rate to keep the miners cool
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
Worker Protection for Uranium Mining Radon and Airborne Uranium Monitoring WWW. BLADEWERX. COM
Public and Environmental Protection for Uranium Mining Airborne Uranium Continuous Air Monitors WWW. BLADEWERX. COM
Public and Environmental Protection for Uranium Mining In-Situ mining leaches the uranium ore from the underground deposit and greatly reduces the volume of above ground waste.
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 • Australia’s Olympic Dam mine is converting to an open pit operation
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 mine’s affect on the public and the environment.
