|Repository Waste Subcommittee to Sponsor Workshop on Hydride Re-Orientation in Zirconium Alloys
ASTM International Subcommittee C26.13 on Repository Waste will sponsor a workshop, “Hydride Re-Orientation in Zirconium Alloys,” which will be held Jan. 31 to Feb. 1, 2007, during ASTM’s January Committee Week in Costa Mesa, Calif. Subcommittee C26.13 is under the jurisdiction of ASTM International Committee C26 on Nuclear Fuel Cycle.
Workshop sessions will address the main issues related to the topic with a goal of formulating an intellectual framework of ideas supporting design and procedural solutions. Some of the suggested areas to be explored are:
• The considerable uncertainty about the critical stress in Zircaloy cladding,
• The amount of radial hydride required to degrade the cladding mechanical properties,
• Effects of this degradation, and
• Whether spent fuel rods can attain stresses above the critical level in storage and/or transportation.
The workshop will begin with 15-minute presentations by each invited speaker on a topic of their choice that relates to the subject of the workshop. The workshop chairpersons will summarize the key questions and issues presented during these presentations. These questions/issues will serve as the topics for the working group sessions. All participants will then discuss these topics and group them into three or four main discussion topics. A series of breakout sessions will be held to discuss the four main topics and the workshop will close with discussions and actions on developing the path forward. //
