Demolizione del vecchio camino e costruzione del nuovo
completed

Demolition of the old chimney and construction of the new chimney

During the operation period, the chimney was used to channel the discharge of gaseous effluents coming from the turbine, the reactor and the Radwaste, all operating in vacuum condition and, thus, requiring a controlled exit point.

FUEL AND WASTE MANAGEMENT

All the irradiated fuel was removed for being later reprocessed. Radioactive waste is safely managed and stored in temporary repositories on the site, while conventional materials, mostly metals and concrete, are reused or recycled.

​​​​​​

ENVIRONMENT

To ensure environmental sustainability, all interventions are designed, implemented and monitored so as not to produce any impact, neither radiological nor conventional, on the environment.

History

Garigliano nuclear plant of Sessa Aurunca was built in four years (1959-1963) by SENN, National Electro-nuclear Company, based on the project of the engineer Riccardo Morandi; the plant started producing electric energy in April 1964. The plant, a BWR (Boiling Water Reactor) belongs to the first generation of nuclear plants, with an electric capacity equal to 160 MWe. This reactor was the first BWR built in Europe. In 1965, the plant was acquired by Enel. The plant continued being operating until 1978, when it was halted for maintenance operations. In 1982 the plant was finally closed. Since then, the safety of structures and plants was maintained to ensure people and environment protection. The plant has produced 12.5 billion kWh of electric energy. In 1999, Sogin acquired the plant to carry out its decommissioning. In 2009, the plant has obtained the Environmental Compatibility Decree (EIA), namely the provision allowing its decommissioning according to the Decommissioning Proposal submitted by Sogin in 2001. As stated by the Ministry of Cultural Heritage and Activities, the EIA involves maintaining the turbine and reactor buildings - designed by the engineer Riccardo Morandi and designated “architectural national heritage” – after the completion of decontamination and dismantling operations. Garigliano plant was the second of the four Italian nuclear plants, after Trino, to receive the decommissioning Decree in September 2012, approved by the Ministry of Economic Development upon the advice of the Nuclear Security Authority and other competent institutions.
