AbstractAbstract
[en] Insurance for large nuclear installations covers mainly four types of risk: third party liability which in accordance with the nuclear conventions, is borne by a nuclear operator following an incident occurring in his installation or during transport of nuclear substances; material damage to the installation itself, which precisely is not covered by third party liability insurance; machinery breakdown, i.e. accidental damage or interruption of operation. Only the first category must be insured. In view of the magnitude of the risk, nuclear insurance resorts to co-insurance and reinsurance techniques which results in a special organisation of the nuclear insurance market, based on national nuclear insurance pools and on the Standing Committee on Atomic Risk of the European Insurance Committee. Conferences of the chairmen of nuclear insurance pools are convened regularly at a worldwide level. (NEA)

L'assurance des grandes installations nucleaires couvre essentiellement quatre sortes de risques: la responsabilite civile qui est a la charge, conformement aux conventions nucleaires, d'un exploitant d'installation nucleaire a la suite d'un accident survenu dans son installation ou au cours d'un transport de substances nucleaires; les dommages materiels causes a l'installation elle-meme et qui, precisement, ne sont pas couverts par l'assurance responsabilite civile; le bris de machine, c'est-a-dire les degats accidentels d'origine mecanique ou electrique; les pertes indirectes ou pertes d'exploitation. Seule la premiere de ces categories doit obligatoirement etre assuree. L'assurance nucleaire a recours, compte tenu de l'importance du risque, aux techniques de la co-assurance et de re-assurance. Il en resulte une organisation particuliere du marche de l'assurance nucleaire qui repose sur les pools nationaux d'assurances des risques nucleaires et sur la commission permanente du risque atomique du Comite Europeen des Assurances. Sur le plan mondial, des conferences des presidents des pools d'assurances nucleaires sont convoquees regulierementOriginal Title

AbstractAbstract
[en] A numerical approach is presented for modelling two-dimensional laminar and turbulent recirculating flows which are confined within complex curvilinear geometries. Vorticity-stream function formulation is used for the mass and momentum equations. Turbulent stresses are modelled using Boussinesq's eddy viscosity concept. The eddy viscosity is calculated from the k-epsilon turbulence model. For handling irregular internal shapes, the flow equations are transformed into a generalized curvilinear coordinate system. The numerical model has been applied to compute flows confined to various complex curvilinear geometries for Reynolds numbers ranging from 10 to 100,000

AbstractAbstract
[en] Numerious review articles have already been published on the biological effects of deuterium. The most important of these effects are briefly recalled with special emphasis on the consequences of deuteriation on living organisms. The toxicity of low doses of deuterium is examined, particularly in the light of a hypothesis associating deuterium with ageing processes. The natural variations of deuterium concentration are considered in this connection. The use of the isotopic properties for modifying the pharmacological efficiency of various substances is also examined. In conclusion, the authors discuss the effects of two other stable isotopes, carbon-13 and oxygen-18. (author)

AbstractAbstract
[en] Following the work undertaken by Duchesne et al., a synthesis of the results obtained since 1968 is presented. Differences up to 10 per mil are observed in the isotopic ratio 13C/12C of the CO2 exhaled by various animals as a function of their diet and especially of the presence in their diet of vegetables characterized by a C4 photosynehetic pathway (such as maize). Weak but significant variations of the CO2 isotopic ratio are also observed during starvation, after injection of hormones which regulate the glycaemia or even simply in relation to the metabolic rhythms of normal digestion; these variations seem to be correlated with the modifications arising in the relative proportion of substrates from which carbon dioxide is formed. Small isotopic fractionations, appearing mainly in bones and fats, were also shown by combustion of various tissues. Moreover, a change in diet (use of corn) affects clearly, not only the exhaled CO2, but also, within a few days, the mean 13C content of organs, mainly in the case of the liver. These metabolic fractionations remain, however, limited enough to use the 13C content, naturally a little higher, of C4 photosynthetic vegetables as a tracer in order to follow some metabolic processes. An application of this is presented by way of a flucose tolerance test

AbstractAbstract
[en] The present study was conducted to evaluate the combined effect of low-dose gamma irradiation and antimicrobial coating on the shelf life of pre-cooked shrimp (Penaeus spp.). Antimicrobial coatings were obtained by incorporating various concentrations of thyme oil and trans-cinnamaldehyde in coating formulations prepared from soy or whey protein isolates. Coated shrimps were stored at 4±1°C under aerobic conditions and were periodically evaluated for aerobic plate counts (APCs) and Pseudomonas putida. Sensory evaluations were performed for appearance, odor, and taste using a hedonic test. Results showed that gamma irradiation and coating treatments had synergistic effects (p < = 0.05) in reducing the APCs and P. putida with at least a 12-day extension of shelf life. Without irradiation, the inhibitory effects of the coating solutions were closely related to the concentration of thyme oil and trans-cinnamaldehyde. No detrimental effects of gamma irradiation on organoleptic parameters (appearance, odor, and taste) were observed. However, incorporation of thyme oil and trans-cinnamaldehyde reduced the acceptability scores for taste and odor

AbstractAbstract
[en] It is known that heavy water has multiple effects in biological systems but these are still far from being fully understood especially those concerning perturbations in basal metabolism. It was shown that there exist isotopic effects which affect the 13C/12C ratio of exhaled CO2 in the case of intermediary metabolism variations induced, for instance, by starvation or hormone injections. It was then interesting to study how heavy water affects this metabolism by the way of modifications at the level of the 13C content of CO2. For this purpose, rats, receiving heavy water in such a way that their blood reaches a 27% content in D2O, were observed and the 13C/12C of their CO2 was measured daily. An important 13C variation was detected following the increase as well as the decrease of the 2H content variations. Unfortunately, it was shown that this effect was mainly related to a variation in 17O content of the CO2 from which the mass is affected in the same way as from a 13C variation. This 17O enrichment comes from the fact (apparently usually neglected) that deuterium enriched waters have not exactly the same content in oxygen isotopes as natural waters. Despite the necessity of this important correction for 17O, a residual effect of 13C variation is still observed

AbstractAbstract
[en] The efficiency of carvacrol, thymol, trans-cinnamaldehyde (Tc) and tetrasodium pyrophosphate (Tp) on the radiosensitization of Escherichia coli and Salmonella typhi in chicken breast was determined. Chicken breast were dipped in a bath of working cultures of E. coli or S. typhi (5x107 CFU/ml). Active compounds were added at the concentration corresponding to ((1)/(30)) of the minimal inhibitory concentration. Samples were packed under air and gamma irradiation was done at doses from 0.1 to 0.7 kGy. The efficiencies of the active compounds against E. coli were 32%, 10%, 3% and 0% for thymol, Tp and carvacrol, respectively. For S. typhi, the efficiencies in the chicken breast were 47%, 19%, 17% and 11% for Tc, Tp, carvacrol and thymol, respectively. Without active compounds, D10 values were 0.145 kGy for E. coli and 0.64 kGy for S. typhi as compared to 0.098 kGy for E. coli and 0.341 kGy for S. typhi in presence of Tc. Under modified atmospheric packaging condition and in presence of Tc, D10 values were reduced to 0.046 for E. coli and to 0.110 for S. typhi

AbstractAbstract
[en] The present study was conducted to evaluate the efficiency of gamma irradiation combined with modified atmosphere packaging as an alternative treatment to ensure the innocuity and the shelf life extension of pre-cured vegetables. Grated carrots were inoculated with Escherichia coli (106 CFU/g) and packed under air or under MAP condition (60% O2, 30% CO2 and 10% N2). The packages were then, gamma irradiated at doses from 0.15 to 0.9 kGy and stored at 4±1 deg. C. E. coli counts were periodically evaluated during 50 days of storage. Results showed that at day 1, an irradiation treatment at a dose of 0.15 kGy reduced by 3 and 4 log the microbial level representing a level of 3 and 2 log CFU/g when samples were irradiated under air and under MAP respectively. However, a level of 3 log CFU/g was detected in both treated samples after 7 days of storage. When samples were irradiated at doses ≥0.3 kGy no E.coli were detected during the whole storage in samples treated under MAP. However, when samples were treated under air, a level of 1-2 log CFU/g of E.coli was detected after 5 days of storage

Study of the thermal behavior of a latent heat cold storage unit operating under frosting conditions

AbstractAbstract
[en] A study is performed of the thermal behavior of a latent heat cold storage unit operating under frosting conditions. This unit is employed to maintain the temperature inside the refrigerated compartment of a truck below 265 K. The system consists of parallel plates filled with a phase change material (PCM) that absorbs heat from the flow of warm moist air. A mathematical model for the system is first presented and, next, validated with numerical and experimental data. It is then exploited to assess the effects of design parameters and operating conditions on the performance of the system. The recommended thickness and distance separating the PCM plates are found to be 50x10-3 and 30x10-3 m, respectively. The results indicate that the performance of the unit is enhanced by turbulent air flow in spite of the increased pressure loss and accentuated frost growth. The unit also performs well even when the surrounding relative humidity is 100%
