ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

PG&E to dredge Diablo Canyon intake system
The owners of the Diablo Canyon nuclear power plant plan to dredge a massive buildup of shoaled sediment from its seawater intake cove.
Pacific Gas and Electric spokesperson Suzanne Hosn said, “The dredging project in the Diablo Canyon marina will remove approximately 70,000 cubic yards of sediment to prevent circumstances that could impact the power plant’s cooling system. Dredging will take place for the first time since operations began because of a rapid increase in sediment.”

The DAC file (Demande d'Autorisation de Création) is the principal document supporting the application for the licensing of ITER. It includes the Preliminary Safety Report (RPrS - Rapport Préliminaire de Sûreté) and the "Impact Study". On January 2008, the DAC was officially submitted to the French Nuclear Authority (ASN).To cope with the requests and recommendations given by the ASN to the earlier ITER Safety Options Report (DOS), CEA had taken commitments dealing with complementary information to be integrated into the RPrS. The necessary work had been implemented by EFDA (European Fusion Development Agreement) and, since its existence, by F4E (Fusion for Energy), in the EISS activities (European ITER Site Study) and in the European Safety Technology Work Programs. The executants of the work have been CEA-AIF (Commissariat à l'Énergie Atomique - Agence ITER France), several European Associations (CEA, CIEMAT, ENEA, FZK and VR/Studsvik) and industry. All of them have been working in full cooperation with ITER Organization (IO). In addition some long term R&D tasks, which will have to be performed in parallel to ITER construction, have been defined and their implementation started. Typical examples are dust management (production, mobilization, diagnostic and removal), combined hydrogen/dust explosion models development and validation, demonstration of the feasibility of prevention/mitigation of in-vessel hydrogen/dust
