With legislators and civic groups expressing their concern over the safety of nuclear waste treatment, Vice Minister of Economic Affairs Woody Duh (杜紫軍) said at the Legislative Yuan in Taipei yesterday that the ministry is planning to set up an independent nuclear waste treatment center.
At a meeting of the legislature’s Social Welfare and Environmental Hygiene Committee, legislators across party lines asked how the ministry, Taiwan Power Co (Tai-power, 台電) and the Atomic Energy Council (AEC) plan to deal with nuclear waste and whether they can ensure safety.
AEC Deputy Minister Chou Yuan-ching (周源卿) said 16,671 spent fuel bundles — high-level radioactive waste — produced by the three operating nuclear power plants are being kept in the plants’ spent fuel pools.
Duh said that because the pools at the first and second nuclear power plants in New Taipei City’s Jinshan (金山) and Wanli (萬里) districts are unable to store all the spent fuel bundles produced in the plants’ lifespan of 40 years, the bundles are to be moved to dry cask storage facilities that are now being built as midterm storage sites.
According to Taipower’s Spent Nuclear Fuel Final Disposal Program Plan, which is now evaluating potential rock formations, the final disposal site is to be decided by 2038 and ready to use by 2055, he said.
As for low-level radioactive waste disposal facilities, Chou said an estimated total number of about 740,000 barrels — including 292,048 barrels produced during their 40-year lifespan and 455,783 barrels produced during the decommissioning process — are to be created by the three nuclear power plants.
Duh said that about 100,000 barrels are stored on Lanyu (蘭嶼, Orchid Island) and others are being kept in storage facilities at the three power plants.
He added that the ministry in 2012 named Taitung County’s Tajen Township (達仁鄉) and Kinmen’s Wuchiu Township (烏坵鄉) as potential sites for building a final depository, but the two local governments have not agreed to hold local referendums to decide the site.
According to Yilan Charlei Chen Foundation president Chen Hsi-nan (陳錫南), who was invited to present to the committee, the design of Taiwan’s dry cask storage does not allow spent fuel bundles to be removed or transported to other sites, because it lacks sufficient vibration-proof and crash-proof material.
The oldest dry cask storage facilities in the US have only been used for 26 years, so Taipower cannot prove that the facilities can keep the spent fuel safe from leakage for 40 years, Chen added.
Meanwhile, He Li-wei (賀立維), a nuclear expert who worked at the Institute of Nuclear Energy Research, said seven hydrogen explosions occurred when the institute tried to remove fuel bundles from pools 26 years ago in Taoyuan County’s Longtan Township (龍潭).
Taipower vice president Chen Pu-tsan (陳布燦) said that although the oldest dry cast storage facilities in the US are just 26 years old, they were designed to be used for more than 40 years, and so are the ones designed for Taiwan.
Duh said three months ago, the ministry decided to establish an independent administrative institution to deal with nuclear waste issues, and public hearings are being held to collect opinions.
BACK TO NORMAL? The move would be part of a gradual easing of curbs monitored by the CECC, which would retain the quarantine mandate if case numbers rise again The Cabinet yesterday approved a plan to next month reopen Taiwan’s borders to all visitors and lift the quarantine mandate for arrivals, provided the nation’s COVID-19 situation does not escalate. The changes are likely to take effect on Oct. 13 as part of a phased easing of border controls that is to start on Thursday next week when a negative polymerase chain reaction test result would no longer be needed, Cabinet spokesman Lo Ping-cheng (羅秉成) told a news conference. Arriving travelers would instead be given four rapid antigen home test kits, Lo said. The three-day quarantine requirement followed by four days of mandatory
‘NO SURRENDER’: A blockade or outlying island seizure would be an act of war, and China’s drills last month have emboldened Taipei in its response plans, an official said The Republic of China Army Command Headquarters has agreed to purchase 5,000 Kestrel close-range anti-armor missiles worth NT$400 million (US$12.63 million) from the Chungshan Institute of Science and Technology, according to the military’s latest arms purchase bid notice. The army asked the institute to complete the order within 13 months, a military source said on condition of anonymity. Kestrel missiles are designed to penetrate armored vehicles and are used in anti-surface warfare, as they feature optical sights and night vision, and can be operated in all weather conditions. The missile has a 400m range, or a 150m range when used for breaching brick
IF THE CHIPS ARE DOWN: The US secretary of state warned that a disruption to the supply of Taiwanese semiconductors would play havoc with the global economy If Taiwan were attacked, the global economy would face devastation, as that is where most of the world’s semiconductors are produced, US Secretary of State Antony Blinken said on Sunday. In an interview that aired on the 60 Minutes television program, Blinken was asked whether instability across the Taiwan Strait would be felt around the world. Blinken said that China has been increasingly aggressive against Taiwan, posing a threat to peace and stability in the region, while economically the world would feel the effects of such aggression. Blinken was interviewed for the program after meeting with Chinese Minister of Foreign Affairs Wang Yi
‘ABSURD’: UN Resolution 2758 expelled the Chiang Kai-Shek government without mentioning Taipei, something the Chinese minister did not acknowledge, Taipei said Taiwan yesterday criticized Chinese Minister of Foreign Affairs Wang Yi (王毅) for “intentionally misinterpreting” a 1971 UN resolution to misrepresent Taiwan’s status to the global community. In his address on Saturday to the UN General Assembly, Wang cited Resolution 2758 as a basis for Beijing’s claim that Taiwan is part of China. He said that Beijing considers Taiwan an “inseparable part of China’s territory since ancient times.” “Only when China is completely reunified can there be enduring peace across the Taiwan Strait... Any move to obstruct China’s reunification is bound to be crushed by the wheels of history,” Wang said. General Assembly Resolution 2758
