In order to reduce water consumption in the nuclear power plant in Angra, Eletronuclear will replace all conventional taps for hydraulic-mechanical ones in the bathrooms of the surveillance area. The measure is an initiative of the Maintenance of Infrastructure Management (GIM.A), responsible for the sanitation system of the company’s units in Angra dos Reis.
After a study of technical and financial feasibility, Eletronuclear decided to purchase eco-efficient taps. The thought of a replacement for sensor faucets was there, but the hydraulic-mechanical, besides being cheaper, are easy to install and to do the maintenance, do not require adjustments in the hydraulic system and are resistant to depredation.
In total, 66 new taps will be acquired, and the return on investment will take place 11 months after installation. According to Denis Castro, engineer and coordinator of the project, the measure will enable savings of at least R$ 17,000 (EUR 4,637) per year. Moreover, it will avoid the annual waste of about 7000 m3 of drinking water as all the water in the nuclear power plant is treated.
This is equivalent to:
The forecast is that all new faucets will be installed by the end of this year. Initially, the replacement will occur only in the controlled area of nuclear power, but the idea is to expand the project also to the protected area and other buildings under the responsibility of Eletronuclear, such as the administration of the villages, the Itaorna Information Center and the Center Training.
The project was realized due to Denis’ specialization in energy efficiency. Full with ideas to be applied at Eletronuclear, the engineer, along with his team, decided to put into practice the knowledge acquired.
Even before making the replacement of these faucets, the team is already working on three other projects with environmental focus. “The first concerns the construction of a single sewage station in the nuclear power plant, where it will be possible to reuse the treated effluent to irrigate gardens, for example. The second aims to reuse rain water after being filtered and chlorinated. And the third one provides the use of photovoltaic panels for energizing the electric carts used in the villages, “he said.
