[en] Sonar - an automated service for selective dissemination of information (SDI) - developed by the Centro de Informacoes Nucleares (CIN) of the Comissao Nacional de Energia Nuclear (CNEN) is described. Emphasis is given to the multibase feature of the system based on the parametric interface between the system and an external data base reading subroutine. (Author)

[en] A comparison between the old and now CNEN (Brazilian Nuclear Energy Commission) organizational structure was performed. The new structure lead to a new IPEN (Nuclear and Energetics Research Institute) organization and also to gave use to a Radioprotection Engineering Area, The principal modification raised a second block already in accomplishment. The main aim of the Radioprotection Engineering Area is to turn personnel team interested, concerned, dexterous, dynamic and competitive on their activities besides to provide it of a continuously improvement and updating about technical activities in radiation protection. From these results an evaluation of possible drawbacks and ways to overcome them will be performed. (author)

[en] The need of technical or managerial information which are selected, analyzed and synthesized led to the creation of the Information Analysis Service from CNEN. This service deals with nuclear energy and related areas. It aims at helping the researchers and managers in obtaining the information necessary for their respective work. The services already implemented and available are described. (Author)

[en] The authors present a progress report on the design and construction of the Brazilian synchrotron light source facility, which is based on a 1.15 GeV (nominal energy) electron storage ring. To date, the first part of the LINAC injector (50 MeV) has been completed and is in operation. Prototypes for all the ring main components - magnets, vacuum chambers, kickers and septa, power supplies, control system, beam position monitors, RF cavity - have been developed in-house and characterized. An update of the production of these components, which is already under way, is presented here. A report will be given on the experience acquired with laser cutting technique for the production of laminated magnets, pioneered by LNLS
