Round table about the application in France of the new EURATOM directive establishing the basic radioprotection standards; Table ronde sur l'application en France de la nouvelle directive EURATOM fixant les normes de base en radioprotection
Started in 2008, the updating works of the existing EURATOM directives are now completed with the publication in December 5, 2013 of the new 2013/59 Euratom Directive in the Official Journal of the European Union. The new directive establishes the basic protection standards relative to the health protection against io…
Review of the generic aging lessons learned (GALL) report for U.S. NPPs
Generic aging lessons learned (GALL) report is a technical basis document issued by U.S. nuclear regulatory commission (NRC) for guiding the review of license renewal application (LRA) of its domestic nuclear power plants (NPPs). By form of tabulations, GALL report addresses the correlation among materials, environmen…
High technology application detanatsionnyh cover forming an abrasive solids layer
The technology applied to the tool surfaces filing detonation coatings that improve tool life significantly reduce the manufacturing cost per unit of output, as well as requiring much less manufacturing space. Hardcourt as an abrasive material has a higher corrosion resistance, wear resistance and red hardness than st…
Surface hardened threaded pipe parts made of high-strength aluminum alloy 1953T1 fatigue resistance
Outstripping superficial plastic deforming various regimes influence on polycyclic fatigue of threaded pipe specimens made of high-strength aluminum alloy 1953T1 has been examined. It’s been shown that the most optimal type of hardening is rolling regime when pipe piece wall depth decrease by 1,5 mm. It’s established…
