  • Nuclear Forensic Science: Analysis of Nuclear Material Out of

    IntroductionNuclear Forensics of Uranium Ore ConcentratesRadiochronometry For Nuclear ForensicsNuclear Forensic CaseworkConclusionsDisclosure StatementNuclear forensic science, or nuclear forensics, is increasingly recognized by the international community as an integral part of a robust nuclear security program. It was specifically identified in the Communiqués and Work Plans of the last three Nuclear Security Summits (in 2010, 2012, and 2014; see http://www.state.gov/t/isn/nuclearsecuritysummit/index.htm) as an important focus area for research. The fundamental tenet underlying nuclear forensics is that identifying the origin of nuclear materials found outside regulatory control can help identify gaps and weaknesses in the physical security and/or safeguards of a particular country or facility, which can then be strengthened in response.1 In addition, any country or organization that considers thwarting international law or practice by trafficking in such nuclear materials might be deterred by the knowledge that their complicity in such trafficking is likely to be identified (Allison 2008).

  • Flow Switches - Intek, Inc.

    Overview of Flow SwitchesWhat Kind of Service Can Our Flow Switches provide?How Do They Work?What Models Are available?How Do I Get One?Flow switches play an important role in regulating the flow rate of fluids through a system. They perform this function by sending a trip signal to another system element (often a pump) that responds by modifying the fluid flow rate as needed. Flow switches are also used for indication of certain process conditions such as flow/no-flow to alert operating personnel by connecting them to indicator lights or audible alarms. Every flow switch has a set point, which is a maximum or minimum flow rate. The set point is typically user-adjustable. When the flow of media reaches the existing set point, the switch prompts the pump (or other mechanism) to turn on or off. The switch can be set to trigger in either low-to-high (e.g., trigger when flow goes from 0 to any flow) or high-to-low (e.g., trigger when flow goes to 0 from any flow value) to match the process requirements. This sequence of events results in the increase or decrease of the flow rate, depending on the requirements of the app...
