novità dalla cina
https://www.hdblog.it/tecnologia/artico ... incidente/ , è un fatto importante perché sono i primi rettori al mondo EPR di classe 3+ , sì li catalogano così. Sono nuovi di pacca , frutto della migliore tecnologia al mondo ,sono di framatome che ne sta costruendo un paio in Uk, eppure .... eppure continuano a dare molti problemi come i reattori di precedente generazione e non risolvono nessuno dei problemi strutturali del nucleare come ad esempio le scorie. Però dovrebbero essere strutturalmente più sicuri
quello che è sicuro invece è l'atteggiamento omertoso delle autorità cinesi e che i reattori della stessa classe che si stanno costruendo in Usa hanno , a causa dei crescenti costi , portato al fallimento di Westinghouse Electric Company .

2015 accounting difficulties
In 2015, concerns were expressed that the value of assets and goodwill in Westinghouse were overstated. Following an accounting scandal in which profits were overstated at Toshiba, leading to the CEO resigning, Toshiba stated that the Westinghouse nuclear business was more profitable than at acquisition in 2006.[20][21]
In December 2016, Toshiba said it expected to write down its investment in Westinghouse by US$2.5 billion,[22] adding that it was possible that their investment in Westinghouse could ultimately have a negative worth, due to cost overruns at U.S. nuclear reactors it was building.[23] In February 2017, Toshiba revealed unaudited details of a 390 billion yen ($3.4 billion) loss, mainly in its US nuclear business which was written down by 712 billion yen ($6.3 billion). On 14 February 2017, Toshiba delayed filing financial results, and Toshiba chairman Shigenori Shiga, formerly chairman of Westinghouse, resigned.[24][25][26] Toshiba considered selling the Westinghouse nuclear business.[27]
2017 Chapter 11 bankruptcy

On 29 March 2017, Toshiba's Westinghouse filed for Chapter 11 bankruptcy, citing a yearly loss for Toshiba that could exceed $9 billion, almost three times its previous estimate.[28][6] The Wall Street Journal reported that four nuclear reactors being built in the southeastern U.S. would be left to an unknown fate.[29] In July, 2017, the co-owners of the V.C. Summer plant announced that the project was terminated.[30] On September 24, 2017, the Post & Courier reported that Westinghouse had hired unlicensed workers to create mechanical and electrical blueprints for the V.C. Summer expansion without having a professional engineer sign off on them which was in violation of state law.[31] The blueprints were often faulty and led to significant delays.[32] The U.S. government had given $8.3 billion of loan guarantees on the financing of the four nuclear reactors being built in the U.S.[6]
Besides the issues with the AP1000 design, the fuel manufacturing division has been profitable, but not enough to cover corporate overheads and support the other divisions. Research and development investment in fuel manufacturing has been low, which has impacted the quality and comparative performance of its fuel compared to competitors.[33]
