NOLDOR S.R.L. offers consultancy services, statistical analysis, development of mathematical simulation models  mainly in the field of hydrology, though is also possible to spread these activities to other applications. Some examples are exposed bellow.

Nuclear power plants in Atucha

A comprehensive hydrological study for Atucha I nuclear power station was carried out including a general analysis about the fluvial framework in the surroundings of  the plants. Later, a study on extreme floods and drought flows was performed on the base of a historical analysis and an important data collection coming from several gauge stations. This information was used to develop a statistical analysis of extreme values and determination of maximum probable events. The future conditions in Parana river and the downstream effects  for different hydraulic works were evaluated afterwards. The report also included a study on curve rectification and a comprehensive analysis about fluvial sedimentology and sediment transport in the nuclear plant canal for cooling water. Finally, a hydrologic balance was carried out involving the analyse of pluvial regime, soils, groundwater and evapotranspiration.

This work was complemented by an extreme drought flow analysis including a study about the hydrologic and hydraulic characteristics in Parana de las Palmas river followed by an analysis of the fluvial regime, tide propagation, winds and extremes events. The cooling water inlet canal for the nuclear power plant was analysed in deep involving geothermic, structural and morphologic characteristics, sedimentation and bed dredging. Making part of the recommendations and conclusions, a floods and drought flows forecast model was provided. Both studies led to the preparation of a complete theoretical work (more than one hundred pages) titled in Spanish "Análisis estadístico de valores extremos. Aplicaciones en hidrología" ("Extreme Value Statistical Analysis. Applications in Hydrology") which can be freely downloaded in this site. Download file.

A study on fluvial traffic and navigation in Parana river was developed as a part of a safety and licensing studies for Atucha II nuclear power station. It included an analysis of the general situation in Parana river and its main harbours. A complete enumeration of ships sailing this river was presented involving different kind of vessels and big ships, especially those carrying hazardous or flammable materials. After analysing different navigation conditions a simulation mathematical model was proposed. Its main goal was to evaluate the risk of eventual collisions and probability of explosions near the nuclear plant.

This project led to the development simulation software for analysis of explosion risk after a ship collision.

Nuclear power plant in Embalse

In occasion of starting the operation of Rio Grande hydroelectric complex, a preventive analysis for Embalse nuclear power station was done. It was related with the safety of such a central.

A study regarding the sitting of storage silos for irradiated fuel elements coming for Embalse nuclear plant was developed.

NOLDOR's staff also participated in evaluation of thermal dissipation for the silos to be used for cobalt-60 storage.



A hydrologic study for sitting of low energy a nuclear power plant (CAREM reactor type) was carried out. San Luis, Argentina.

Irradiation plants

A study about ozone production in cobalt-60 irradiation plants was envisaged.


A feasibility study about application of ionising radiation sources for sewage treatment was done. With this work the project and construction for the Sewage Treatment Plant (PIBA) started, Tucuman, Argentina. There was also some collaboration in the basic design and preliminary calculations for such a plant.

Another comprehensive hydrologic study with regard the sitting of PIBA was developed. This work included analysis of weather, hydrogeology, impact of hydroelectric stations, seismic, floods and so on. As in other cases, statistical, deterministic and stochastic analysis  were included.
