On a cherche d’autre part a en donner une presentation elementaire, accessible aux lecteurs peu familiarises avec les problemes de thermalisation; dans cet esprit l’expose a une forme didactique, et comporte des rappels de notions bien grtuit comme par exemple le formalisme de Westcott. The resonance self-shielding corrections for the 0. First, a set of actual critical experiments were chosen which contained the various material and geometric properties present in typical LWR transport containers.

For a better exploitation of these reactors a modular computer code Apollo-II has been developed. We present an accurate calculation of the mass spectrum of supersymmetric particles, a calculation of the relic density of supersymmetric black matter, and the constraints that we can infer from models.

The global analysis of bearing loads and displacements is done with a numerical model, in which the plastic jacked pipe is idealized as a beam, batient the effect of the soil is idealized by spring elements with non-linear force displacement characteristics. Two methods for pin power reconstruction were developed: The determination of stress in a rotating disk plane myr symmetry normal to the axis of rotation has been studied by a number of investigators.

The experimental uncertainties, even if lightly superior to those previously edited, remain inferior to the uncertainties of the calculated values.

These transients arise rgatuit flow or reactivity jtr occurring in a part of the core.

Les resultats cherches sont approximatifs. In the second part we find by a variation method a formula for estimating the Laplacian of a batimenf, which may be divided into parallelepipeds for which the Laplacian are given. Magnetic resonance only workflow and validation of dose calculations for radiotherapy of prostate cancer.


A process of re-estimating the 56 Fe nuclear data was implemented on the basis of feedback from these two experiments and the RDN code. An existing numerical model is extended with regard to the new findings and while taking vertical displacements into account.

In this model, the processes are displayed in the single apparatus and coupled to each other in the systemic context. The passive magnetic suspensions operate using attractive or gratiit forces exerted callcul permanent magnets. This is accomplished by determining the code’s bias, or systematic error, through a comparison of computational results to accepted values obtained experimentally. Thanks to our developments, it has been made possible, for the fist time, to calculate the continuous adjoint flux for an actual and complete reactor core configuration.

The two biggest obstacles to a stronger market penetration of absorption refrigerators are their high cost and the size of the apparatus, which are due to the inaccurate methods for plant design. This work presents the methodology used for the evaluation of experimental data, some results obtained cwlcul the application of these methods, and some examples of the data available in the Handbook.

Not only ca,cul they can readily achieve measuring accuracies in the parts-per-million range, but they also incorporate sophisticated algorithms for the transformation calculation of the measured resistance or voltage to temperature. None of these models has ever been validated by comparison with the actual real life practice of recycling.

Calculation of control rods in rectangular reactor, and applications ; Calcul des barres de conteole dans un reacteur rectangulaire et applications This paper describes a new method for evaluating the error in the results of computation of an algorithm. Development and validation of a criticality calculation scheme based on French deterministic transport codes.

The objective of the proposed method is a better knowledge of the spatial energy distribution SED supplied by multimodal cavities. When your moving at home or in a shop who has time to stop and add fractions convert them to decimals and divide into metric or standard numerals. This allows to improve accuracy of the neutron transport calculations that may help in designing the high performance commercial VHTRs.


The calculation is developed in accordance with the AP Commonly-used functions are applied to represent the off-axis softening, increasing primary fluence with increasing angle ‘the horn effect’and electron contamination. In order to achieve this the following topics are discussed.

The mechanical effects due to the strains, thermal or not, of steel structures supporting or surrounding graphite blocks. For the current study the functions were applied to a cargo ship’s full scale propeller, on which the severe cavitation erosion was reported.

The comparison of calculations and measurements shows that the computer code calculations resulted in both overestimations and underestimations of the external doses for different recycling activities.

Animal studies are highly relevant for basic medical research, although their usage is discussed controversially in public. Nous utilisons enfin, cette batimrnt pour calculer l’antireactivite des barres perpendiculaires a l’axe dans une pile cylindrique. The different elongate structures used by the hydrocarbon industry are, in most cases, subjected ta a cathodic protection system consisting of sacrificial anodes or an impressed current.

Useful for take-offs, estimating, budgets, material lists, etc. A test of validity is suggested with the aid of which the applicability of the calculational models can be checked in any concrete case, and the misleading of the reactor operators by gross misinterpretation of the radiochemical data can be avoided.

The computational approaches used for the estimation of the photon energy deposition is examined. For conversion functions, the calculation error is at least ten times smaller than the thermometer effective resolution for the particular probe type. Local differences in batimfnt calculations were concluded not to have clinical relevance. The benchmark exercise has resolved a potentially dangerous inadequacy in dissolver calculations.
