AbstractAbstract
[en] Radiation control panels with programmed systems have developed at the CEA over the last few years. Each monitored location is provided with an monitoring station containing: - a radiation detector and associated electronics (the output signal is normalised calibrated pulses), - an alarm unit to warn personnal of any danger inside the detection zone covered

AbstractAbstract
[en] Radiation control panels with programmed systems have been developed at the CEA. Each monitoring station contains a radiation detector and associated electronics and an alarm unit to warn personnel of any danger within the detection zone. The need to make the control panels more reliable and available and, at the same time, more flexible has led to the use of a microprocessor in each unit. The monitoring station thus became autonomous, processing the signal from its detector and translating it into dose equivalent rate or contamination level and triggering the light and sound signals. The central mini-computer, which formerly handled the alarm system, is given over to record-keeping tasks and may be dispensed with in small-scale facilities. (H.K.)

AbstractAbstract
[en] The B.F.S.A. plutonium monitor (monitor with sequential filter to measure plutonium and other transuranium element aerosols) includes two units: the CFSA sampler with sequential filter for alpha aerosols, and the processing unit in conjunction with its signalling unit. The main parameters of the CFSA and its principle being presented, the description of the sampler is given

AbstractAbstract
[en] The problem of the ''alarm'' detection of radiative contamination by plutonium and other transuranic elements has not been satisfactorily solved with the equipment development over the last few years (EAR, MDPu, DFF.Pu ...): - inadequate detection sensitivity (flow rate, detectors, energy decay of particles in the filter element or in the detection space, influence of background); - problems of aerosol capture and collection with unsuitably designed instruments; - research and development too centred on Pu 239 detection alone. A more thorough approach to the requirements of reprocessing plants, plutonium recycling laboratories, CEA users with material to replace or new facilities to equip has shown up the need to develop a captor and an RC signal post for the measurement of atmospheric contamination by plutonium and other transuranic aerosols, especially Pu 238. Preliminary work has shown that such an apparatus must be designed with a new detection head by which a flow rate of 100 l/mn may be obtained under satisfactory sampling and collection conditions

Le probleme de la detection ''alarme'' de la contamination atmospherique par le plutonium et autres transuraniens n'a pas ete resolu de facon satisfaisante avec les materiels developpes ces dernieres annees (EAR, MDPu, DFF.Pu ...): - sensibilite de detection insuffisante (debit, detecteurs, degradation en energie des particules dans le support filtrant ou dans l'espace de detection, influence de bruit de fond naturel); - problemes de captation et de collection des aerosols au niveau des appareils mal apprehendes; - effort de recherches et de realisation trop axes sur la seule detection du Pu 239. Une approche plus approfondie des besoins des usines de retraitement, des laboratoires au cours du recyclage du plutonium, des utilisateurs du CEA qui ont a renouveler leur materiel ou a equiper de nouvelles installations, a montre la necessite de developper un capteur et une balise TCR pour la mesure de la contamination atmospherique par les aerosols du plutonium et autres transuriens, en particulier pour le Pu 238. Les travaux preliminaires accomplis ont mis en evidence la necessite de concevoir un tel type d'appareil en utilisant une nouvelle tete de detection qui permette d'obtenir un debit de 100 l/mn dans des conditions de prelevement et de collection satisfaisantesOriginal Title

AbstractAbstract
[en] The nuclear basic plants of the CEA group are very diversified: experimental reactors, hot laboratories, particle accelerators, fuel reprocessing plants, etc... These nuclear basic plants have always been highly controlled and monitored radiologically, with an instrumentation which has changed with the time. Instrumentation of the third generation is described here

AbstractAbstract
[en] Developments in radiation protection systems which have occurred within the CEA are described. Such systems enable irradiation and contamination risks to be quantitatively determined and monitored. A monitoring station is defined to be a suitable radiation detector (with its associated electronics) and audible and visible means of alerting personnel. The outputs from all the monitoring stations are fed to a central control station where they are recorded and acted upon. The practical experience obtained using microprocessors on the monitoring stations and a minicomputer in the central station is discussed; 30 units are connected to the central minicomputer in order to control an effluent treatment plant. (U.K.)
