AEC ad­mits four ob­jects fell into Nuke 2 re­ac­tor

The China Post - - LOCAL - BY SUN HSIN- HSUAN

Four items accidentally dropped into the re­ac­tor core dur­ing a ren­o­va­tion project for the Sec­ond Nu­clear Power Plant ( Nuke 2,

) in Septem­ber 2014, though the in­ci­dent was en­tirely left out of the Atomic En­ergy Coun­cil’s (AEC,

) con­struc­tion re­port, Demo­cratic Pro­gres­sive Party Leg­is­la­tor Cheng Li-chun ( ) re­vealed yes­ter­day morn­ing at the Leg­isla­tive Yuan.

Ac­cord­ing to Cheng, a bolt, a C- clamp, a C- clamp bolt and a drop hanger fell into the re­ac­tor core of Nuke 2 last Septem­ber when it un­der­went round of ren­o­va­tions.

The con­struc­tion re­port later con­ducted by the AEC, how­ever, failed to men­tion the in­ci­dent, con­clud­ing that the ren­o­va­tions “were car­ried out smoothly with­out de­fects,” added Cheng. The leg­is­la­tor went on to ques­tion the AEC’s qual­ity con­trols and its ap­proval of Nuke 2’s op­er­a­tion, say­ing, “fallen ob­jects can­not be re­trieved (from the re­ac­tor) once the power gen­er­a­tion process has be­gun.” Cheng went on to rhetor­i­cally ask, how can peo­ple trust that nu­clear power plants are safe ... with such false re­ports?

In re­sponse, AEC Chair­man Tsai Chuen-horng ( ) said that three out of the four items were re­trieved in Oc­to­ber 2014. More­over, while the fi­nal bolt re­mains un­found, Tsai claimed that the Tai­wan Power Com­pany (Taipower,

) con­ducted an in­spec­tion and determined that the bolt most likely fell into the re­ac­tor, but not into the core it­self.

Mean­while, the chair­man of the Nu­clear Science & Tech­nol­ogy As­so­ci­a­tion (NuSTA, ) said that all re­ac­tor cores are set up with fil­ters for sit­u­a­tions such as this, and there­fore even un­der the worst-case sce­nar­ios — which have now been ruled out by Taipower — the fil­ters will pre­vent ob­jects from fall­ing into the fuel bun­dle. Tsai said that given th­ese mea­sures, there are no safety con­cerns.

As the AEC re­port made no men­tion of the in­ci­dent, the coun­cil will take full re­spon­si­bil­ity for the er­ror and avoid any sim­i­lar faults in the fu­ture, Tsai said. He fur­ther ex­plained that all de­fi­cien­cies recorded in the con­struc­tion re­ports will be care­fully re­viewed be­fore any fu­ture ren­o­va­tions take place. “For ev­ery op­er­a­tion, the AEC sticks to this re­view­ing pro­ce­dure, there­fore con­struc­tion safety is al­ways taken se­ri­ously,” said Tsai.
