Chinese nuke shield is first in world
Print Edition
A Chinese heavy machinery maker has produced the world’s first shielding equipment for the new-generation high-temperature gas-cooled nuclear reactor (HTGR).
The first shield is expected to be installed at the beginning of 2015 in Shidaowan Nuclear Power Station under construction in Shandong Province, which will be the world’s first HTGR nuclear power station when it begins operation in 2017.
Yesterday, Cao Keshun, spokesman for the Taiyuan Heavy Machinery Group Co, said the equipment includes a spent fuel trolley and a shielding case. The equipment weighs 330 tons and has an automatic positioning accuracy within 3 millimeters.
HTGR is an advanced nuclear reactor featuring several new safety measures. China has independent intellectual property rights over the development of the reactor in Shidaowan.
Conceptually, the HTGR has an outlet temperature of up to 1,000 degrees Celsius, Cao said.
The ground trolley, which transports used fuel, and shielding case are key equipment for the reactor, allowing for fully automated operation.
