Abstract

The site of INGA offers the opportunity to construct a series of connected dams capable to produce 45.050 MW. To date, only two connected dams have been constructed namely Inga I and II. Inga III project is still in progress. This paper presents the challenge of sediment transport in channels of intakes water for turning turbines and stagnant water of unknown origin in some dam’s plots faced by INGA site. The NDT on concrete, radiotracers and nucleonic gauges or X rays density gauges are among methods particularly used to solve some problems posed by the above challenge for the maintenance of the two connected dams. Specifically, the paper is reporting, by giving some collected data respectively produced by the DR Congo General Atomic Energy Commission through the CREN-K (Centre Régional d’Etudes Nucléaires de Kinshasa), Kinshasa University and the Congolese Company of Electricity (SNEL), the fruitful partnership between SNEL and CREN-K for the period going from 1986 up to 2022.
