For several years, the French Atomic Energy Commission (CEA) has developed modelling tools for ultrasonic NDT configurations. Implemented within the CIVA software for multiple technique NDT data acquisition and processing [1,2], these models are not only devoted to laboratory uses but also dedicated to ultrasonic operators without special training in simulation techniques. This approach has led us to develop approximate models carrying out the compromise between as accurate as possible quantitative predictions and simplicity, speed and intensive use in an industrial context.

The French Atomic Energy Commission (CEA), Valduc Centre, has developed an aerial system of gamma cartography named HELINBUC. This equipment enables, in a few hours, the establishment of a map of radioactivity over areas several dozen to several hundreds of hectares in size, by identifying radioelements present, with a sensitivity between the level of natural radioactivity and that of artificial radioactivity resulting from a large-scale accident.

Hurd and Saint-James [H5] of the French Atomic Energy Commission have shown that TBP diluted with kerosene is a selective solvent for the fractional extraction of zirconium from hafnium. These workers recommend using an organic phase consisting of 60 v/o (volume percent) TBP and 40 percent refined kerosene, and an aqueous phase 3 TV in nitric acid and...

Monomers with low molecular weights will diffuse into the wood more rapidly than polymers such as PEG. In a second phase, their in situ radiation curing will form wood consolidants that are much stronger than PEG. However, this method requires very heavy irradiation equipment, which is usually available only in nuclear research centers. The irradiation cell dimensions and the 7-source geometry limit the size of the artifacts. For mainly these reasons, the radiation process was applied in very few institutions and in most cases only at the experimental level. The Nucleart Laboratory, which routinely conserves waterlogged wood by this technique, is located in the Grenoble Nuclear Research Center of the French Atomic Energy Commission. 

Long-term studies performed by the CEA (French Atomic Energy Commission) resulted in the formulation of the so-called R7 and T7 glasses. Characterization studies have verified the main properties of the final products and have established the glass specifications. The vitrified waste specifications were subjected to peer review by an independent commission of nuclear specialists. 

Phenix is France s experimental fast breeder reactor that is located in Marcoule and is operated by the French Atomic Energy Commission (CEA). The CEA, has decided to renovate the aging plant to extend the life expectancy of the reactor. The program reqnires field inventory and inspection of equipment to support the component life-span evaluation studies. The presence of liquid sodium and the high temperature of the reactor coolant system even at cold shutdown - between 150 and 180°C - make inspection of Fast Breeder Reactors (FBR) a difficult technical challenge. Framatome-ANP has in particular conqileted fom innovative nondestructive tests at Phenix ...
