ASTM International recently developed its, Roadmap in Support of Commercial Nuclear Power, to provide a practical set of plans for updating ASTM nuclear energy standards in conjunction with the Nuclear Energy Standards Coordination Collaborative (NESCC). The ultimate goal of the roadmap, a document that spells out these plans in detail, is to ensure a safe and economical source of electricity for now and in the future. A link to the Roadmap can be found in the ASTM Nuclear Portal at…, Technical Contact:, Stephen Byrne, Phone: 860-342-7363; pnsbyrne@yahoo.com, ASTM Staff Contact:, Joe Koury, Phone: 610-832-9804; jkoury@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org R elease #9321

New ASTM Nuclear Fuel Cycle Standard Provides Guidelines for Gathering Physical and Rheological DataObtaining data from the measurement and calculation of physical and rheological properties of radioactive solutions, slurries and sludges is essential in developing appropriate simulants for the design and testing of retrieval, transport, mixing and storage systems for treating radioactive materials. A new ASTM International standard provides guidelines for gathering this data. ASTM C1752 , Guide…

New Section of Website Collects ASTM Nuclear-Related Work in a Single Source ASTM International standards play an important role throughout the nuclear energy industry. In order to tie together the nuclear-related activity being conducted across its committees, ASTM has added a nuclear portal to its website ( www.astm.org ). The portal, which gathers together all of ASTM’s standards developing…

Sealant manufacturers will use a new ASTM International standard to evaluate new products and changes to these products due to exposure to weather. The new standard, ASTM C1735 , Test Method for Measuring the Time Dependent Modulus of Sealants Using Stress Relaxation, is under the jurisdiction of Subcommittee C24.20 on General Test Methods , part of ASTM International Committee C24 on Building…, ASTM Committee C24 Next Meeting:, Jan. 8-10, 2012, Ft. Lauderdale, Fla., Technical Contact:, Christopher C. White, Ph.D., National Institute of Standards and Technology, Gaithersburg, Md., Phone: 301-975-6016; christopher.white@nist.gov, ASTM Staff Contact:, Stephen Mawn, Phone: 610-832-9726; smawn@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #9005

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…

New Advanced Ceramics Standards from ASTM Cover Fracture Mirror Size Analysis, Tensile Strength DataSubcommittee C28.01 on Mechanical Properties and Performance, part of ASTM International Committee C28 on Advanced Ceramics, has recently approved two new standards, ASTM C1678 , Practice for Fractographic Analysis of Fracture Mirror Sizes in Ceramics and Glasses, and ASTM C1683 , Practice for Size Scaling of Tensile Strengths Using Weibull Statistics for Advanced Ceramics., ASTM C1678 —Bringing Consistency to Fracture Mirror Size Analysis, Fracture mirror size analysis is a powerful quantitative tool for the interpretation of broken ceramic and glass articles. While this type of analysis can be used to determine the stress in a part at the instant of fracture, inspection and interpretation procedures have often varied, resulting in uncertainty in stress estimates. ASTM C1678, Practice for Fractographic Analysis of Fracture Mirror…, ASTM C1683 —Scaling Strength Values, ASTM C1683, Practice for Size Scaling of Tensile Strength Using Weibull Statistics for Advanced Ceramics, provides methodology to convert fracture strength parameters estimated from data obtained with one test geometry to strength parameters representing other test geometries. Stephen Duffy, chair of civil engineering, Cleveland State University, and C28 member, says that companies producing…
