The minister confirmed that thick, seasonal fog that rolls in from the sea had caused a build-up of salty crystals on insulators covering transmission lines and led to a malfunction at the plant, sparking a fire when back-up generators were engaged.

"Although Taipower had scheduled a clean-up of the current insulators between March 17 and March 20, it was caught by surprise by the incident on the night of March 17," Lin said.
Indeed, Lin was at pains not to describe the incident as a nuclear accident, instead preferring to call it a power transmission problem, adding that there was no radiation leak.
While not blaming Taipower directly for the incident, he did say there was "room for Taipower to improve" and suggested increasing the frequency of maintenance work on transmission lines and replacing damaged insulators.
Power supply was restored to the plant within two hours of the stoppage, according to Taipower.
Lin said it would take three weeks to repair the damage and additional time after that to run tests.
This latest incident was likely to spark renewed debate over whether Taiwan should rely on nuclear power for energy. In February, President Chen Shui-bian's (陳水扁) anti-nuclear government bowed to opposition pressure and decided to resume construction of a US$5.5 billion nuclear plant, the nation's fourth.

A category four emergency could lead to an overall evacuation of local residents, according to Taipower's security guidelines.
Taipower said it had declared a category 3A emergency because the power outage lasted more than 15 minutes.

"This incident will strengthen Taipower's ability to deal with such events," Hsi said, adding that with improved maintenance measures it was unlikely such an incident would occur again.

She warned that this poses a grave risk to the future management of the nation's Fourth Nuclear Power Plant.
Lin, however, said the Fourth Nuclear Power Plant will be much safer than the other three, and said he would not give an order to stop construction of the Fourth Nuclear Power Plant, despite the incident.
A signaling system malfunction disrupted high-speed rail (HSR) services beginning at 8am today, with trains temporarily reduced to three northbound and three southbound trains per hour as authorities conduct inspections. The malfunction occurred on a section of track in Miaoli County during pre-operation checks early this morning, forcing northbound and southbound trains to use a single track, the HSR operator said. The regular schedule has been replaced with three hourly trains offering only nonreserved seating in each direction, stopping at every station, it said, adding that business class cars would still have reserved seating. Departures from terminal stations are scheduled at the top
Taiwan is still in the process of assessing the possibility of recruiting workers from Eswatini, the Ministry of Foreign Affairs said yesterday, adding that its goal is to help Eswatini upgrade its vocational training centers. If there are plans to recruit workers from Eswatini, safeguarding national security, protecting public health and ensuring the employment rights of Taiwanese would be prerequisites, Department of West Asian and African Affairs Director-General Yen Chia-liang (顏嘉良) told a news conference. Key considerations would also include filling labor shortages in specific industries, and fostering bilateral professional and technical exchanges, he said. Yen was asked about the progress of labor
VERBOSE VESSELS: A CGA cutter and a China Coast Guard exchanged verbal barbs for more than a day in Taiwanese-controlled waters before the Chinese vessel left The Taiwanese and Chinese coast guards had a standoff near the strategically located Pratas Islands (Dongsha Islands, 東沙群島) in the north of the South China Sea, the Coast Guard Administration (CGA) said yesterday. The two sides engaged in intense radio exchanges over sovereignty claims during the 33-hour standoff. China Coast Guard vessel 3501 eventually left the restricted waters, 26.6 nautical miles (49.2km) west of the Pratas Islands, at 5pm yesterday, the CGA said. Lying approximately between southern Taiwan and Hong Kong, the Taiwan-controlled Pratas are seen by some security experts as vulnerable to Chinese attack due to their distance — more than
A US uncrewed surface vessel (USV) encountered multiple Chinese warships during an autonomous transit of the Taiwan Strait, US defense company Seasats said in a statement on Wednesday. Seasats announced that a Lightfish USV had completed the first autonomous transit of the Taiwan Strait. Over five days, the USV traversed the entire length of the Strait while constantly monitoring surface vessel traffic, the company said. The Lightfish encountered multiple Chinese warships, one of which was a Chinese People’s Liberation Army Navy (PLAN) Type 056 corvette, it said. The Chinese vessels were operating “well within Taiwan’s exclusive economic zone without transmitting their identity via the
