L'ormai ex centrale atomica di Muehleberg non presenta più un rischio nucleare. Tutti gli elementi di combustibile esaurito sono infatti stati trasferiti al centro di stoccaggio temporaneo di Würenlingen, in Argovia. Lo comunica l'azienda elettrica bernese BKW.
Per trasportare i 418 elementi sono stati necessari 66 viaggi a partire dall'aprile 2022. L'operazione è stata completata 16 mesi prima della scadenza fissata. La radioattività sul sito della centrale, spenta nel dicembre 2019, è così stata ridotta di oltre il 99%.
Ora l'impianto non contiene più materiali nucleari fissili e non necessita più di raffreddamento. Nei prossimi anni l'obiettivo sarà quello di eliminare la radioattività residua sul sito.
L'eliminazione degli elementi combustibili è la condizione essenziale per passare alla seconda fase di smantellamento, per la quale BKW ha già chiesto l'autorizzazione all'Ispettorato federale della sicurezza nucleare. Al termine di questo secondo stadio il sito sarà completamente esente da qualsiasi radioattività.
Mühleberg: completata una prima tappa del processo di smantellamento della centrale dismessa
