Invented in the early 1990s, the tomographic gamma scanner is used in the nondestructive assay of radioactive waste contained in drums or cans. In the last 10 years, TGS technology has been industrialized, with systems operating in South Korea, the United States and Europe. A new ASTM International test provides users with a means of streamlining TGS procedures and practices, and it will be…

A proposed new standard being developed by ASTM International Committee E17 on Vehicle-Pavement Systems will be the first to describe how truth-in-data should be applied to traffic monitoring data collection, summarization and reporting. WK25280 , Practice for Highway Traffic Monitoring Truth-in-Data, is under the jurisdiction of Subcommittee E17.52 on Traffic Monitoring. Current traffic…

Being able to compile and interpret data on how traffic turns through an intersection could have an impact on future environmental and safety decisions regarding intersection geometry and traffic control. However, until recently no standard has existed to properly obtain and use this data. Now, ASTM International Committee E17 on Vehicle-Pavement Systems has approved E2667 , Practice for…

A type of lime that has been used in construction since ancient Roman times is now covered by an ASTM International standard. ASTM International Committee C07 on Lime has approved ASTM C1707 , Specification for Pozzolanic Hydraulic Lime for Structural Purposes. The new standard is under the jurisdiction of Subcommittee C07.02 on Specifications and Guidelines. According to Margaret Thomson, the…

The use of rolling devices can provide a means to evaluate the adhesion of weather seals, for quality control in new installations, general evaluation of existing installations, and the investigation of water and air leakage through building enclosures. In order to better facilitate the use of rolling devices, ASTM International Committee C24 on Building Seals and Sealants is developing a…

A proposed new ASTM International standard will provide a method for a comparative evaluation of limestone sources available for use in flue gas desulfurization (FGD) applications. The proposed standard, WK20129 , Test Method for Evaluating Limestone for Use in Wet Flue Gas Desulfurization Applications by Reactivity, is being developed by Subcommittee C07.05 on Chemical Tests, part of ASTM…

In response to requests from fuel producers around the world, ASTM International Committee C26 on Nuclear Fuel Cycle has developed a standard for using the total evaporation method to determine uranium or plutonium composition. The new standard, C 1672 , Test Method for Determination of Uranium or Plutonium Isotopic Composition or Concentration by the Total Evaporation Method Using a Thermal…

Neutron absorbers have been used for criticality control in spent nuclear fuel pools and in spent fuel transportation casks for decades. However, since the late 1980s, as spent fuel storage pools have been filled, utilities have transferred spent fuel into dry dual-purpose (storage/transportation) canisters. The neutron absorbers used in dual-purpose canisters are subjected to different operating…
