AbstractAbstract
[en] This paper describes the three main types of research and development (R and D) international cooperations that exist at the French Commissariat a l'Energie Atomique (CEA) in the domain of nuclear reactors. These are: the valorization of French R and D, the direct or indirect support to industrial nuclear development, and the support of the French economical and industrial policies. The cooperation with Japan in the domain of light water and fast breeding reactors, future reactors, fuel cycle, and plutonium management is given as an example. (J.S.)

AbstractAbstract
[en] This educational document comprises 4 booklets in a folder devoted to the presentation of the ANDRA's activities in geological research laboratories. The first booklet gives a presentation of the missions of the ANDRA (the French agency for the management of radioactive wastes) in the management of long life radioactive wastes. The second booklet describes the approach of waste disposal facilities implantation. The third booklet gives a brief presentation of the scientific program concerning the underground geologic laboratories. The last booklet is a compilation of questions and answers about long-life radioactive wastes, the research and works carried out in geologic laboratories, the public information and the local socio-economic impact, and the storage of radioactive wastes in deep geological formations. (J.S.)

AbstractAbstract
[en] Plant life management for CANDU type reactors is essential part of good performance, in developing the scope for rehabilitation and life extension. Its implementation is essential for securing good operation past rehabilitation. It includes the following aspects of plant life management: technical, regulatory, utilities program and supporting research and development. Being a multifaceted task it integrates numerous activities and programs, namely, inspection, maintenance (surveillance, preventive maintenance), designer assessment of data, feedback from supporting research and development activities, information exchange among similar plants. It is a joint effort between Utilities (NBP, HQ, QNPC, NASA, RENEL, etc), AECL and AECB

AbstractAbstract
[en] In this paper the correlation between inspection effectiveness, inspection qualification and risk informed inspection will be treated in view of harmonisation of inspection of nuclear plant components. Through the different phases of the PISC programme the necessity has been demonstrated to show the effectiveness of the inspection through a formal process of qualification in order to ensure that a certain level of effectiveness has been reached. Inspection qualification is indeed the way to quantify the capability level of inspection techniques used. The targets to be met by the inspection is information which should be obtained from risk based analyses. (author)

AbstractAbstract
[en] The inner surface of vessels of pressurized water reactor is protected from corrosion by a stainless steel cladding hot-layer in many cuts. Therefore, the surface irregularities generate spurious echoes that can either mask or be misinterpreted for echoes from possible defects. Probes are calibrated on a specific reflector (side drilled holes in a steel block). The echo arising from it is used as a reference to quantify echoes measured during an examination. The study aims at simulating echographs of the vessel inspection so as to help the analysis of actual measurements. Three models are developed to compute echoes from cladding surface irregularities, echoes from planar defects and the reference echo, respectively. The radiated field is modelled using the Rayleigh integral, the integration of the incident beam with the cladded surface is treated under Kirchhoffs approximation and the reception of reflected waves involves reciprocity between radiation and reception. An extra physical hypothesis allows a fast algorithm to be developed for simulating the Bscan image obtained by transducer scan. The reference echo is also computed under Kirchhoffs approximation. The field refracted inside the material is modelled by an extension of the Rayleigh integral using the geometrical optics approximation. The model for computing diffracted echoes from crack tips is based upon the Geometric Theory of Diffraction. The model for predicting echoes from cladded surface irregularities has been validated by comparing theoretical predictions with experimental measurements. (author)

AbstractAbstract
[en] The period of 1993 1994 has seen the first experiences of the Vivitron and the multi detector E.U.R.O.G.R.A.M.They concern study of properties of superdeformed nuclei. The CRN is invested on the way of an other priority project for the decade to come: the preparation of experience near the future L.H.C collider at C.E.R.N.. Different contributions to researches, developments for detectors are explained. (N.C.)
