Combined effects of radioactive, chemical and thermal releases to the environment1975
AbstractAbstract
[en] A comparison was made of the behavioural responses to temperature of Atlantic mackerel, Scomber scombrus, bluefish, Pomatomus saltatrix, and tautog, Tautoga onitis, held under controlled laboratory conditions. When the temperature was either raised or lowered from normal levels, juvenile and adult bluefish and adult Atlantic mackerel, all pelagic species, responded similarly by increasing swimming speed as much as 61-190%. This response was interpreted as a manifestation of behavioural avoidance of a particular level of temperature, indicative of capability for directive movements relative to ambient thermal conditions. Comparing the response of pelagic species to earlier work on tautog, a demersal species, it was clear that avoidance capability is dependent upon the behavioural repertoire of the individual species. The significance of the results, regarding distribution of fish and response potential under thermal stress, is discussed. (author)

AbstractAbstract
[en] According to all the facts known until now, it may be stated that with the current cooling powers up to about 3,000 MW, the waste heat released through wet cooling towers results in no disadvantageous consequences for the environment. This is also valid for the concentration of several cooling towers of comparable size. Small changes of individual meteorological elements in the immediate neighborhood can no more be considered a hazard for the environment than negligible increases of temperature and rainfall in large cities and industrial agglomerations, known since a long time ago. It therefore seems justified to no longer consider the waste heat emission of large cooling towers set up in a flat, well ventilated terrain as an important part in the official licensing procedure and to carry out the time-consuming efficiency calculations only in individual cases or with especially unfavorable ground conditions. Climatic effects of a larger extent cannot be excluded if by application of higher cooling powers and concentration of groups of power stations the energy supply to the atmosphere occurs on larger areas and with higher vertical energy flows. Until now, the long-term effects on the regional climate which may arise as a consequence of the vapor release of a larger number of wet cooling plants by a change of the low-energy radiation conversion in the atmospheric boundary layer, cannot be assessed. By this mechanism lasting changes of the temperature level, the atmospheric stratifications, and the cloud climatology will be possible by means of variations of the conditions of insulation and emission of radiation.

Nach allen bekannten Tatsachen laesst sich feststellen, dass bei den heute ueblichen Kuehlleistungen bis etwa 3.000 MW die ueber Nasskuehltuerme abgegebene Abwaerme keine nachteiligen Folgen fuer die Umgebung mit sich bringt, auch fuer die Zusammenfassung mehrerer Kuehltuerme in vergleichbarer Groessenordnung. Kleine Veraenderungen einzelner meteorologischer Elemente im unmittelbaren Nahbereich koennen ebensowenig als Gefaehrdung der Umwelt betrachtet werden wie die seit langem bekannten geringfuegigen Temperatur- und Niederschlagserhoehungen in Grossstaedten und industriellen Ballungsraeumen. Es erscheint deshalb gerechtfertigt, die Abwaermeemission grosser, im ebenen, gut beluefteten Gelaende aufgestellter Kuehltuerme nicht mehr als schwerwiegenden Teilbereich in behoerdlichen Genehmigungsverfahren zu betrachten und die aufwendigen Wirkungsberechnungen nur noch in Einzelfaellen bei besonders unguenstigen Gelaendeverhaeltnissen vorzunehmen. Klimatische Auswirkungen groesseren Ausmasses sind nicht auszuschliessen, wenn durch Uebergang zu hoeheren Kuehlleistungen und Zusammenfassung von Kraftwerksgruppen die Energiezufuhr in die Atmosphaere auf groesseren Flaechen und mit hoeheren vertikalen Energiefluessen erfolgt. Nicht abzuschaetzen sind bisher die regionalklimatischen Spaetfolgen, die sich infolge des Wasserdampfausstosses einer groesseren Anzahl von Nasskuehlanlagen durch Veraenderung des langwelligen Strahlungsumsatzes in der atmosphaerischen Grundschicht einstellen koennen. Es werden hierdurch auf dem Wege ueber Aenderungen der Ein- und Ausstrahlungsbedingungen anhaltende Veraenderungen des Temperaturniveaus, der atmosphaerischen Schichtungen und der Bewoelkungsklimatologie moeglich sein.

AbstractAbstract
[en] Many studies have been carried out both in France and abroad to determine the magnitude of the thermal effects due to cooling of conventional or nuclear open-circuit electricity-generating stations. After an account of the main effects observed and the information derived from these results the discussion centres on the conclusions drawn from American research by the two bodies responsible for checking the impact of nuclear stations on the environment in the United States. The possible effects on aquatic organisms exposed to hot water discharges are of two kinds: the direct thermal effects (changes in the metabolism, growth rate and period of sexual maturity increase in mortality, etc..) and the indirect thermal effects (asphyxia due to a drop in the dissolved oxygen concentration, changes in the sensitivity to certain toxic substances, in resistance to infection, in the food chain)

De nombreuses etudes ont ete realisees tant en France qu'a l'etranger afin de determiner l'importance des effets thermiques dus a la refrigeration des centrales electriques classiques ou nucleaires en circuit ouvert. Apres avoir decrit les principaux effets observes et en avoir tire les enseignements, il est cite les conclusions tirees des etudes americaines par les deux organismes qui controlent aux Etats-Unis l'impact des centrales nucleaires sur l'environnement. On distinguera dans les effets possibles sur les organismes aquatiques soumis aux rejets d'eaux chaudes: les effets thermiques directs (modification du metabolisme, du taux de croissance, de la periode de maturite sexuelle, augmentation de la mortalite, etc...) et les effets thermiques indirects (reactions asphyxiques dues a une baisse de concentration en oxygene dissous, variation de la sensibilite a certaines substances toxiques, modification de la resistance aux infections, modification de la chaine alimentaire)Original Title

AbstractAbstract
[en] Various aspects of the relationship between nuclear energy and the sea are examined in this chapter since, at this moment in time, the sea appears to be a source of cooling water for nuclear power stations; nuclear propulsion has upset a certain number of data on naval forces and the uranium ressources in the water of the seas are sometimes mentioned. But the sea could also become the depository for radioactive waste. Therefore care must be taken to preserve the quality of the marine environment by preventing sizeable amounts of radioactive matter from contaminating it
[fr]
On examine dans ce chapitre differents aspects des relations entre energie nucleaire et ocean. En effet l'ocean apparait actuellement comme une source d'eau de refroidissement pour les centrales nucleaires; la propulsion nucleaire a bouleverse un certain nombre de donnees sur les forces navales et les ressources en uranium de l'eau des oceans sont parfois evoquees. Mais l'ocean pourrait devenir aussi le receptacle des dechets radioactifs. Il faut donc veiller a preserver la qualite du milieu marin en evitant que des quantites importantes de corps radioactifs ne viennent le contaminerOriginal Title
