[en] As organizations grow more complex in operation and more global in scope, assets and technical integrity become key success factors. A company's asset integrity business process needs to be mapped in order to 1) provide a proper overview of operation and business processes, 2) identify all critical interfaces and 3) ensure that all gaps and overlaps in processes are eliminated. Achieving asset integrity requires companies to sustain their activities and identify the hazards, weaknesses and objectives of their strategic assets. Technical integrity emphasizes a complete overview of technical conditions and related information, and the ability of the companies to document the technical state of its assets. It is based on an integrated view of the current state of operations, and the identification of all critical interfaces, in order to ensure that all gaps and unnecessary overlaps in processes are eliminated. Companies look increasingly at their asset integrity management system as a means to extend the life of their assets, beyond the original design conditions and production capacity. Establishing an asset integrity management system requires the documentation of the company's technical integrity management, a strategy and the processes for carrying it out, identifying gaps; selecting corrective interventions and conducting follow up actions. The paper discusses various aspects of asset integrity management, including its planning and implementation. We begin with an introduction to asset technical integrity, provide some theoretical backgrounds, present a model we call 5C and conclude with a summary and discussion.
[en] Usually the safety of nuclear power plants is regarded as a technical question. Thereby humans only as a part of the man-machine system play a safety-relevant role usually. On this picture, the national regulation of this safety, the 'nuclear supervision' is designed. An innovative investigation of the Yale School of Management has concerned with the incidents around the so-called Millstone reactors in Waterford, Connecticut, and the economic collapse of the regional supplier Northeast Utilities (NU). The change of the corporate culture of the operator of the nuclear power station to a shareholder value orientation has released this 'enterprise disaster'. This investigation permits a first insight into the changed requirements on supervision, which goes beyond the nuclear supervision and which includes the price control in view of this change of the corporate culture
[en] Since 2004, the Direction General of the the energy and raw materials asks every years the prefects to evaluate the situation of the wind power in the departments. This 2007 inquiry confirms the positive development of the wind energy in France. A synthesis of the four last year is presented. (A.L.B.)
[en] D'amico risk groups have been classified to estimate the probability of biochemical recurrence after treatment for localized prostate cancer. The evolution of patients that have received external radiotherapy were analyzed according to the risk group. The medical records of 50 patients between 2003 and 2004 have been assessed and has observed the evolution of Prostatic Specific Antigen after treatment ends, at Hospital Calderon Guardia. Adverse reactions resulting from radiotherapy treatment and the organs most affected by the same have been documented nith the possibility to compare the results of similar studies in the literature. The best performance is given by receiving concomitant hormonal therapy that high risk patients of D'amico without receiving. (author)
[es]Los grupos de riesgo de D'amico han sido clasificados para estimar la probabilidad de recidiva bioquimica posterior al tratamiento para el cancer de prostata localizado. La evolucion de pacientes que han recibido radioterapia externa se ha analizado segun el grupo de riesgo. Las historias clinicas de 50 pacientes entre los años 2003 y 2004 se han evaluado y se ha observado la evolucion del antigeno prostatico especifico despues de finalizado el tratamiento, en el Hospital Calderon Guardia. Las reacciones secundarias derivadas del tratamiento con radioterapia y los organos mas afectados por el mismo han sido documentadas con la posibilidad de comparar los resultados de estudios similares en la literatura. La mejor evolucion es dada al recibir hormonoterapia concomitante que pacientes de alto riesto de D'amico sin recibirla. (autor)
[en] Escuela de Ingenieria Electrica at the Universidad de Costa Rica has developed a procedure for the improved use of a PASCO brand Spectrophotometer of the Laboratorio de Fotonica y Tecnologia Laser Aplicada. The program has used DataStudio for the application in radiometric surveys in LAFTLA. Important conclusions have been obtained by the assembly of optical experiments, software and data collection and analysis, such as the behavior of a emitting source radiation known as black body and its relation to the temperature, wavelength and intensity of light. The user guide has been detailed exposing calibrations of the sensors, the definition of constants needed for obtaining parameters and assembly and commissioning of the equipment. (author)

[en] In an effort to solve the problem of discrepant half life data sets, several statistical data handling procedures were recommended in the past for the purpose of evaluation, adjusting the previously evaluated data or eliminating the discrepant entries from a group of data sets. However, considerable problem faced by the data evaluator is finding the best method of achieving a recommended value from a discrepant set of data and its associated uncertainty. We have measured in this study the activity of 137Cr, 90Sr, 134Eu and 57Co sealed sources from which their half-lives were evaluated. We also used Normalised Residual, Raja vel, Weighted Mean, Unweighted Mean and Bootstrap Statistical techniques to determine the half-lives and compared it with experimental values obtained. Salient features of the statistical techniques and the experimental measurements are discussed and new half life values hereby recommended for the nuclides.
[en] In this summarized presentation, after having indicated the distribution of radioprotection events among different sectors (electricity, transport, nuclear industry, industry and services, medicine, research), the author indicates that her presentation (not included) will more precisely analyze these data, and thus comment the main causes and origins of these incidents which are recorded in a database belonging to the ASN (the French Nuclear Safety Authority)
[en] The appropriate managing of hazardous wastes is a problem little dealed in the wastes management in the country. A search of available information was made about the generation and handling to internal and external level of the hazardous wastes by national industries. It was worked with eleven companies of different types of industrial activities for, by means of a questionnaire, interviews and visits, to determine the degree of integral and suitable handling of the wastes that they generate. It was concluded that exist only some isolated reports on the generation of hazardous industrial wastes and handling. The total quantity of wastes generated in the country was impossible to establish. The companies consulted were deficient in all stages of the handling of their wastes: generation, accumulation and storage, transport, treatment and final disposition. The lack of knowledge of the legislation and of the appropriate managing of the wastes is showed as the principal cause of the poor management of the residues. The lack of state or private entities entrusted to give services of storage, transport, treatment and final disposition of hazardous wastes in the country was evident. (author)
[es]El manejo apropiado de los desechos peligrosos es un problema poco abordado en la gestion de residuos en el pais. Una busqueda de informacion disponible fue realizada sobre la generacion y manejo a nivel interno y externo de los desechos peligrosos por parte de las industrias nacionales. Se trabajo con once empresas de diferentes tipos de actividades industriales para, mediante un cuestionario, entrevistas y visitas, determinar el grado de manejo integral y adecuado de los desechos que generan. Se concluyo que existen solamente algunos informes aislados sobre la generacion de desechos industriales peligrosos y su manejo. La cantidad total de desechos generados en el pais fue imposible establecerla. Las empresas consultadas presentaron deficiencias en todas las etapas del manejo de sus desechos: generacion , acumulacion y almacenamiento, transporte, tratamiento y disposicion final. La falta de conocimiento de la legislacion y del manejo apropiado de los desechos se muestra como la principal causa del mal manejo de los residuos. La falta de entidades estatales o privadas encargadas de dar servicios de almacenamiento, transporte, tratamiento y disposicion final de desechos peligrosos en el pais fue evidente. (autor)
