Based on applications and communications received by the Nuclear Regulatory Commission (NRC), more than 30 new nuclear power reactors are expected to be under construction by 2020. In addition, more than 100 existing reactors must be re-licensed—including an assessment of the integrity of the reactor core after 50 years of operation.
Because it has been more than 25 years since a new nuclear power reactor has been constructed in the United States, material science and construction techniques have changed substantially, and many of the construction codes and techniques and documentary standards of the past century need to be updated. New and advanced nuclear reactor designs, for example, require standards in areas such as fire protection, seismic requirements, and graphite-core support structures.
The NESCC was formed to address these needs. In addition to NIST and ANSI, the panel is supported by the NRC, the Department of Energy (DOE) and more than 30 private sector standards development organizations, professional societies and industry associations.
The new report explains the rationale for the collaboration; a review of the draft group charter; a discussion of the NESCC’s organizational structure; and identification and discussion of potential standards topics for technical task groups to address. NESCC is accepting proposals throughout the summer for task groups; interested individuals may contact NIST’s Ambler Thompson (firstname.lastname@example.org; (301) 925-2333). The chosen task groups will meet during the next NESCC meeting, scheduled for the week of Dec. 7, 2009.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
