China’s nuclear industry and high‑speed trains are world class

And the state has been crucial in making them so

Within the cavernous factory of Dongfang Heavy Machinery Company (dfhm), a state‑owned firm based in Guangdong province, lies what looks like a suit of armour built for a mis‑shapen giant. In fact, they are parts built to contain something even more fearsome—nuclear reactors and the high‑pressure, high‑temperature steam that they produce. Some are still being worked on. Some are almost ready to head off, by barge, to sites along the southern coast where China is expanding its nuclear‑power industry with greater ambition than any other country in the world.

In 1996, with the help of Framatome, a French firm with a lot of nuclear history, China built a reactor at Ling Ao, 60km (37 miles) from Hong Kong. Part of the deal was that Framatome would share its know‑how. It helped a local firm that had previously made boilers learn how to make the hulking metre‑thick metal vessels that can safely contain a nuclear reaction. That firm became dfhm. As well as the main reactor vessels, it also now makes the steam generators which turn the nuclear heat into something which can drive turbines and make electricity. Zou Jie, a dfhm executive, says his firm’s products are now competitive with Framatome’s.

One reason for this progress is that China’s nuclear industry has gained experience quickly. In the past 20 years China has built nuclear plants faster than any other country; its nuclear capacity is now 43gw, third only to that of France (63gw) and America (99gw). Unlike in those two countries, though, China’s capacity is growing. And whereas in 1996 just 1% of the value of its first nuclear plants came from domestic firms, that figure is now 85%.

Die Bahn kommt – in China wirklich

Posted by hkarner - 15. Dezember 2019

In Rekordzeit hat China sein Schnellzugnetz ausgebaut, heute verfügt das Land über mehr Gleiskilometer als der Rest der Welt zusammen. Viele Menschen steigen vom Flugzeug um. Noch ist die CO2-Ersparnis gering, doch das soll sich ändern.

Von Georg Fahrion, Peking, Spiegel.de

An einem Dezembertag schließen sich auf dem Shanghaier Bahnhof um 11.59 Uhr die Zugtüren, um Punkt zwölf rollt der G12 nach Peking los. In nur viereinhalb Stunden wird der Zug 1318 Kilometer zurücklegen, eine Distanz wie von der Ostsee zum Mittelmeer. Während der Fahrt reißt das WLAN kein einziges Mal ab.

Bequeme Sitze, großzügige Beinfreiheit, und acht Minuten nach Abfahrt beginnt der Bordservice: Eine Stewardess überreicht jedem Fahrgast ein Getränk, Cracker und Wasabi-Erbsen. Wenig später feudelt eine Frau in schwarzer Dienstmädchenuniform den tadellos sauberen Boden im Großraumwaggon. Um 12.22 Uhr zeigt ein Display an, dass die Höchstgeschwindigkeit erreicht ist: 339 km/h. Den Rest des Beitrags lesen »
